He is a large, muscular middle-aged man with broad shoulders, a tiny waist, dark skin and a bald head. His eyes are normally hidden behind a pair of small, round-framed sunglasses that have two upwards spikes on their temples. He has thick black eyebrows. His nose is large and wide, with a jawline to match. His mouth is also quite big with full lips and deep laugh-lines.
He wears the standard outfit for the American Colony, consisting of a long button-down with zigzag hems, downwards-slanting zippers across both breasts and upwards-slanting zippers on both thighs. Brody wears his buttoned to the top and with the sleeves folded upwards. He also has standard pants, tucked into knee-height black boots. He's got a spiked collar-style necklace with studs and more zigzag pattern. Around his waist, there are two side-release buckle belts, holding up several pouches filled with work tools. He has a shotgun slung across the small of his back. [8]

Brody is pacifistic and dislikes needless bloodshed, similar to Ukyo . This was seen when he simply laughed off suspicions of Gen's deceit and scolded one of his soldiers for being quick to want to pursue the enemy, rather than save their leader and enemy after they were trapped. Because of this attitude, the Kingdom of Science believed him to be the best person suited for negotiating with the plan of establishing Corn City and Senku even gave him the revival fluid recipe to show good faith. Even when forced to have the Kingdom of Science gunned down, he shed tears of regret for his act.
When discussing terms with Minami Hokutozai , he wanted to sternly let her know that his colony were in charge, though backed off after Nikki Hanada stepped in and intimidated him. Amused by the girls' ferocity, Brody agreed to ally with them and establish Corn City. [9]

As a middle aged man, Byakuya grew his hair just above the nape of his neck and has a buzz-cut beard and mustache. His hair is white with dark tips, and his eyes are brown, similar to Senku.
During his time on Treasure Island, he adopted to wearing his former astronaut uniform as a cloak.
Before he died of old age while panning for metals, his appearance greatly resembled a much taller version of Kaseki with the exception of not being bald, most noticeably the beard, facial features, and overall build.

Byakuya was a very supportive and caring father, who loved his son Senku. He went as far as selling his car to give Senku the materials he needed to pursue his passion for science. He was a caring person who was willing to work hard in order to give Senku a great future.
Byakuya was a kind, playful, and mischievous man who always found a way to amuse himself and keep things lighthearted, no matter the stakes. He was a firm believer in fun and levity being crucial to humanity's survival. He was a courageous man who did whatever he could to help other people, always finding something to do with his talents and skills.
His sense of humor could be somewhat dark, but unfailingly, Byakuya would always shed light on what were otherwise heartbreaking circumstances. His unbreakable will allowed him to withstand the loss of his friends, his son, and his world, something that very few people could do. This unbreakable resolve was something that he passed down to his son, along with a lack of regard for formality or decorum, preferring to be honest, earnest, yet never failing to be kind to others.
A teacher to the end, he sent his son a coded message in The Hundred Tales passed down to his descendants in Ishigami Village , knowing that Senku would be able to discover the record that was placed inside his grave marker. During the recording, he made sure that Senku and whoever was with him knew about the amazing things of modern time. Byakuya also gave lessons to the children of his former colleagues that would pass down to new generations.
Byakuya was charming, his belief in the power of fun to sustain humanity catching on to everyone he met. His strength of spirit caused him to become a natural leader, inspiring the people he met, and in turn being inspired by others. Ultimately, Byakuya seemed to embody the spark of humanity's best traits: honor, hope, compassion, curiosity, adaptability, and daring.

Carbo is a handsome young man with spiky blonde hair. He keeps it up using a rope around his forehead, similar to the one Chrome wears like a hachimaki. A single strand falls between his eyes like Magma 's does. His nose is slim and his mouth is of an average size. His eyebrows are very short and tend to be slightly inclined. His eyes are extremely narrow and he has visible tear troughs. Carbo's usual expression makes him look like a sly delinquent.
He wears a long-sleeved, dark green tunic that reaches his ankles, tied with a rope belt. His sleeves are usually rolled to the elbow, and the collar is popped in such a way that it covers his neck.

Carbo is brusque and occasionally uses clipped speech, such as "y'think" (you think). [4] He is never shown being helpful in any way, mostly hanging around the village waiting for things to happen.


Dr. Stone

Carlos is a muscular young adult with curly black hair which he covers with a white bandana. He wears a white unbuttoned shirt and has earrings on both sides.

Carlos seems to be of energetic, gleeful character. He seeks Luna's attention and praises her often.
Carlos is shown to have great persistence keeping himself awake for thousands of years in order to serve Luna.
He appears to have morals, as he and Max were startled by Stanley's intent on killing the enemies' science leader.


Dr. Stone

Chalk is a small dog with perfectly white fur and no markings. His ears flop over a little and his nose is fully black. His fur is quite short, the only exception being his tail which is slightly bushy. Chalk wears the village rope around his neck as a collar, marking him as one of the Ishigami villagers.
When Chalk gets older, he gains darker markings across his back, upper head and on the outside of his legs similar to a shiba inu. His ears have also perked up rather than stay floppy like they were as a puppy, and his tongue no longer lolls out of his mouth.

Chalk is quite a playful dog, frequently found playing with the foxtail millet. He rarely barks, but if he does it's to get someone's attention or out of excitement rather than from being scared or surprised.


Dr. Stone

Charlotte is a young woman with a short bob and light-colored hair. Her hair is smooth on her head, ending in slightly spiky ends at the back, with her bangs gently framing her face and a single thick strand falling across the middle. Her eyebrows are straight and thin, and they taper towards the end. Charlotte's eyes are half-moon-shaped and tilted slightly inward, giving her a bit of a bored expression. Her petrification marks are two symmetrical lines under her eyes, like the tears on mime makeup.
Her outfit is a black skin-tight latex unitard with a turtleneck collar. It has a zipper running down the back of it, ending at the base of her spine between a square of buttons. She has a wide belt with extra protrusions at her hips. She wears a set of gloves the same style as Stanley's, with a large cuff and studs along the edge. When she was first introduced, she wore similar tasseled armor to Stanley in addition to her unitard.
After the 7-year timeskip, Charlotte's new outfit would see the addition of the Americans' standard zigzag-patterned uniform tucked into the belt around her waist. Following her revival, Charlotte had lost her petrification scars. [3]

Charlotte is a dedicated and extremely loyal person, especially when it comes to Stanley. She usually seems serious and plays by the rules, but she isn't afraid to banter during the dogfight with Ryusui . She is quite confident in her abilities, believing the enemy was foolish enough to challenge her. However, it is shown that even she can become frustrated, as she was in disbelief when the enemy overcame her in their aerial battle.
However, unlike some of her comrades, Charlotte isn't completely unsympathetic. After Suika saves her, Charlotte begins to hesitate when accepting the order to kill all on sight, due to the enemy showing her mercy. [5]


Dr. Stone

Chelsea is a young woman with a ponytail ending in pronounced swirls. She has short bangs that are swept outward in both directions, with smaller pieces of hair sticking out in front of her ears. She has wide, round, cutesy eyes and her upper lip seems to always be in a '3' shape.
Initially, Chelsea was dressed in a large pumpkin, similar to Suika 's helmet. She used it to store her tools in. In addition, Chelsea has the "fuzzy sickness", resulting in a terrible squint.
Soon after meeting, Senku and the others create a set of glasses for her, also outfitting her with a generic explorers outfit consisting of shorts, a large belt, and a jacket with rolled sleeves and several pockets. She replaced her singular large pumpkin with a smaller one smashed over her pith helmet, and another medium-sized pumpkin as a knapsack. A smaller pumpkin rests on her belt, presumably to act as another container. She also wears a whip on her hip. Her socks are pulled up to just below her knees, and her ankle boots have a single button clasp with no laces.

Chelsea is a happy girl who seems friendly and excited, especially after seeing people for the first time after petrification. She also insists she is "besties" with Dr. Xeno after bumping into him in the national park prior to the petrification event, which might show it doesn't take much to befriend her. [9]
While Chelsea is generally enthusiastic and composed by most things she has shown a comedic shock as seen when she freaked out by Senku suggesting they create a fax machine.
Her straightforward and carefree attitude when talking earns her a nickname of "Chelsea the Blunt" by Gen when she ask Luna directly about her weight. This makes her seem a little rude when combined with her tendency to point at people.
In alignment with her amicable personality, Chelsea opposes Xeno's ideas of ruling the world with an iron fist. [10]


Dr. Stone

Chrome is a young man of average height and build. He has round, brown eyes and matching spiky brown hair, and he keeps a rope tied around his head like a headband. He's most often seen with a cheerful expression.
His usual outfit consists of a short-sleeved, dark blue shirt, matching pants, a rope belt, and two cross-body satchels that contain materials he's collected. When he was first introduced, Chrome donned a cape that matched the color of his outfit, hemmed with rope.
Later in the series, his outfit it upgraded to less primitive satchels that have eyelets on the straps [17] , and a shirt with the logo of the Kingdom of Science on the sleeves. His headband is also remade by Suika , and has more frayed edges. [7]

Chrome is a highly energetic person with a lot of passion and curiosity. He is genuinely interested in science, although at first, he only knows it as sorcery. Chrome is confident in his intellect, enough so to go toe to toe with Senku despite getting destroyed in a battle of wits. [18] He also has a tendency to refer to something as "bad" when he thinks it is cool or amazing.
Chrome has a deep love of science, though he admits his expertise and knowledge lies mainly in exploration, particularly pertaining to rocks and minerals and gathering them. [16] He even becomes offended when Ryusui refers to Chrome as an amateur explorer. [19] He was amazed by new things such as vehicles, inventions, and being petrified. He is loyal to his friends and, while lacking in physical abilities compared to some of the other characters, he is still able to think of clever solutions out of dangerous situations.

Chrome's enthusiastic passion.

Chrome is also exceedingly brave and loyal, managing to withstand Tsukasa 's threats and refusing to speak about Ishigami Village or the progress of Senku's inventions. [20] In addition, while he is usually a loudmouth, he knows when to keep his mouth shut. He loves science and, in many ways, is an accomplished scientist in his own right, managing to create chemical reactions from the rocks he collected through frequent trial and error [16] (reactions which were only made known in the seventeenth century).
As someone with a lot of drive, Chrome is naturally quite combative, and his first instinct seems to be challenging people who may encroach on his self-imposed roles in the Kingdom. This is evident when he first hears of Senku, [21] when Tsukasa wants to "erase science", [22] when Why-man appears, [23] when Chelsea appears, [24] [25] when Ryusui suggests he's a less capable explorer, [19] and when Taiju dares imply natural diamonds are stronger than science-made. [26]
Chrome appears rather naive when it comes to romantic affairs, or perhaps he's simply not interested in romance. He is unaware of what people are implying between him and Ruri, [27] [28] [29] [30] [31] [32] but seems to think marriage is the next step once he's finished all his inventive projects. [33]
In addition, he is naturally inquisitive and loves helping make inventions. When he was left out of making the automobile, he was notably disheartened. When he managed to ride a hot air balloon for the first time, he was both amazed and frustrated by the progress of the modern era prior to petrification and wanted to learn about it. Also, in spite of his naivety when it comes to the outside world, he is shown to be wary of those he distrusts, evident when he did not trust him and Senku being alone in a cave with Magma as he believed Magma would attempt to murder them.
Chrome is selfless, especially when it comes to his friends, as he entered the village tournament that would determine Ruri 's husband even though he's not a fighter, but did not mind who married her so long as she would be cured. [34] He refused to stay behind in the gathering of sulfuric acid for Ruri, being angered at Senku for wanting to do so. Instead, he was willing to put his life on a line looking after Senku, and expected the latter to do the same for him. [35]
Though at first threatened by the arrival of Senku, [36] another "sorcerer," the two quickly become close friends due to their mutual love of science [37] and he becomes Senku's main ally and confidant in Ishigami Village when it comes to their plans and inventions as the three often use their science and manipulation to find ways of creating a bloodless war against Tsukasa's Tsukasa Empire and later to go against the Why-man .
Chrome shares some of Senku's deviousness, but not to the same degree as Gen does. Regardless, thanks to his levelheaded thinking and analytical prowess, Chrome is the only member of the Five Wise Commanders to not be a pre-petrification human.


Dr. Stone

Connie was a short, slim woman with pale skin and a delicate face. She had hair that was short around the front safe for two bangs reaching down to her cheeks, and two long braids at either side of her head that were tied near the ends, and the remainder puffed like a pompom. Her eyes were small with a more or less almond shape, and a dark, reddish-pink in color. Connie had a generally thin build, save for her notably wide hips.
As an astronaut aboard the ISS, she wore a purple polo shirt and fitted shorts with the customary Velcro strips of the ISS crew.  After living on Treasure Island for some time she could be seen wearing a raggedy blue dress visually similar to the ones that would become popular among women at Ishigami Village . Of all people in modern times, Shovel wears her hair in a way that is somewhat reminiscent of Connie's.


Dr. Stone

Darya had short, blonde hair similar to a bowl cut terminating on downward spikes on her forehead. She had large lavender eyes and eyebrows that were just a thin arched line, full lips, and pale skin. Her face was thin with puffy cheeks. [3] Her figure was moderately curvy.
Upon introduction she wore pants with Velcro strips as it's typical for the ISS crew, and a pale blue polo shirt, with the collar unbuttoned. After living on Treasure Island for some time, Darya grew her hair out and her clothes became tattered, also wearing a long skirt instead.

Darya has been shown to be quite aggressive. She is very protective of her research, considering them like her babies.
Although she would occasionally make fun of her husband, she was highly supportive of him, and would cheer for him when he stepped forward to take a leading position. She was otherwise playful and teasing, often joking about being the one granting the crew of the ISS permission to breathe oxygen.
Other than her research, she was not attached to personal items, and was happy to hand over her wedding ring, so its diamond could be used to cut a record made of glass.
She was also quick to act when it came to rescuing her friends, being fearless to the risks involved. It was her who pushed for a second emergency landing with the Soyuz capsule to rescue Shamil , Connie and Lillian when their capsule landed on the open ocean and tipped over leaving the hatch under water. Later on, she would also venture out to sea with Yakov hoping to reach the mainland and find medicine to treat Connie's pneumonia; they were never seen again.
Kohaku took plenty from her personality far down the family tree, including her habit of making a "3" shape with her upper lips which was mostly shown in the reboot .


Dr. Stone

Dia is a woman with long blonde hair that drapes softly over her shoulders, parted towards the left side. A few of the front segments are slightly shorter and fall across her face. She has thin eyebrows that taper towards the outer ends with a high arch. Her eyes are heavy-lidded and have a single eyelash coming out of the ends, giving her a seductive cat's eye look. Her lower lashes are also quite thick. She has a small button nose and very full lips, with her lower lip larger than her upper one. She has slight smile lines around her mouth, giving her an air of mature elegance.
She wears a long blue dress, reaching below her calves, with a fluffy white fur shawl across her shoulders. The neckline is cut quite low, exposing her cleavage. She wears the village rope tied directly under her bust rather than on her waist.

Not much is known about her personality as she is never shown speaking nor reacting to anything.


Dr. Stone

En is a short, fat woman with bobbed blonde hair with two-tiered bangs, the middle part being the shortest and the sides curling inwards. Her eyes are small and almond-shaped, and her eyebrows are of uniform thickness and arched. She has a small nose. Her mouth has no visible lips, but has pronounced nasolabial folds at the corners of her mouth and dimples on both sides. En's face shape is oval with large cheeks and a double chin.
She wears the village rope around her neck, tied at the front. Her dress is sleeveless with a high collar, and the same shade of olive-green as Sagan's tunic.

Like Ganen, En seems to prioritize food and be a gourmand. Unlike her husband, however, she seems to be a rather happy, joyful person and is always shown smiling.


Dr. Stone

Francois is a short person of very petite build and ambiguous gender. They have a round face with sharp eyes and often sport a serious expression, their hair is always arranged in neat corkscrew curls and likely much longer than it appears to be. Francois has a petrification scar in the shape of a star on the back of each hand, but they're rarely visible as they often wear gloves.
Francois is typically seen in their butler uniform; a dark blazer with striped cuffs and padded shoulders, a striped sash, a light colored ascot, medium length and slightly flared pants, and light colored boots with tall heels. When baking [11] or cooking [12] they wear a white long-sleeved baker's uniform, likely over their regular butler's attire and they also sport a white baker's hat.
The star-like scars on their hands disappeared after their second revival, but they soon recreate them with war paint alongside the rest of the Kingdom of Science following Tsukasa 's revival.

Francois is an incredibly hardworking and driven individual, with an outstanding ability to work under duress, they truly take pride in their work and never fail to tackle any challenge that may arise.
They usually appear pleasant, calm and collected, as it's part of their work ethos, but like with anything they do, they don't skimp on showing emotion when its due. Francois truly loves their job as a butler and they take great pride in delivering the best service possible. Their job is so entwined with their everyday life that it crosses the barrier to being their general lifestyle and they are very keen to expand their already vast skill set.
Francois generally enjoys making people happy with their service, and often thinks one step ahead, preparing things before they are even asked for. Francois also has a tendency to hide their fatigue and only take breaks when no-one can see them. [13]


Dr. Stone

Ganen is a man with short blonde hair that sticks up at the front. He is slightly overweight and has a double chin. His eyes are small but round, and his eyebrows are small but thick and arched. He seems to take after his mother and is generally found smiling (unless he's being overworked by Senku ).
Like most of the villagers, he wears a deep blue tunic with a rope around the waist. Similarly to his father, he also has a rope across his body; however, Ganen's holds two leather pouches rather than being decorative.


Dr. Stone

Garnet is a young woman with long blonde hair and large red eyes with visible eyelashes. Her lips are more prominent and darker than her sisters'. She also has bangs that reach the tops of her cheekbones and frame her face with an errant thick strand falling between her eyes. Her eyebrows are thin and tilt downward.
Her outfit consists of a long, turquoise-blue, tube-top-style dress with no sleeves. It has a high slit on the right side which is held together with a thin brown string, going up to her hip. The top hem is slightly rolled over, exposing the undyed brown underside. She also wears a matching fabric collar around her neck, attached with a piece of rope wrapped around her neck and tied in a bow on the right side. Another rope is tied around her right thigh, exposed by the slit.
Additionally, she has a passing resemblance to her ancestor, Lillian Weinberg . According to Kohaku , she and her sisters are the prettiest women in the village. [3]

Garnet appears to have a similar personality to her other two sisters as she is usually seen discussing boys. She seems to talk slightly more than the others. Out of the three, she prefers physically strong men.


Dr. Stone

Gen is a slim young man of average height with pale skin and strong hands and not much else. [12] His hair is bicolored, with the left half being short and black and the right half being white with longer strands around his face. Prior to his petrification, all of his hair was black, but it was already partially white before becoming petrified. [13] His eyes are dark and shadowed as if with eyeliner or fatigue, and angled upwards into a sharp, cunning slant. His eyebrows are stubby, lacking a tail.
His petrification scar is a jagged mark running down from his left eye with a mouth-like wedge across his cheekbone. This line varies in appearance depending on what Gen is doing, such as becoming flower-like when mimicking a woman's voice [14] or extra jagged while scheming. [15] His petrification scar is healed by his second depetrification. After Tsukasa's revival, he used paint to recreate his scar. [16]
He wears a lavender-pink Japanese-style overcoat over a wheat-colored yukata, tied with an unhemmed and jagged brick-orange obi under a thin rope, tied at the front. Gen wears undyed but fitted pants that gather slightly at the ankles. He lacks proper footwear and walks barefoot.
Later, Gen replaces his outfit with a similar overcoat over a yukata, but rather than it being laced up at the front of his neck, it's tied with a necktie, and his sash is a piece of fabric rather than rope. He also wears sack-like shoes similar to Senku's original ones. [17]

Gen is a proficient liar and skilled manipulator, with no fixed policies regarding his approach to life, [18] making him dangerous as a foe and untrustworthy as an ally. He is the self-proclaimed world's smoothest talker, and of course, he uses all these traits to reliably help his friends over and over again.
He takes pride in his abilities as both a magician, and as a mentalist, with his knowledge of the human psyche. He is a skilled actor, fiercely in control of his body and emotions even when in danger: he remains rational and calm at spear-point, [19] poleaxe-point, [20] gunpoint, [21] or deep in enemy territory, undergoing questioning. [22] He is confident and is shown to have nerves of steel, even in the face of death. In all cases, he only shows the parts of him he wants to show, owing to his manipulation tactics. However, this façade is not always present, as Gen appears to react freely in shock whenever Senku brings up his next planned invention. [23]
While not as academically gifted as Senku, Gen shows an average understanding of modern innovations and scientific knowledge, acting as the bridge between a scientist and a layman. [24] He uses his abilities to promote cooperation and enthusiasm, motivate allies, conduct negotiations, and outsmart enemies. He tends to shift between acting as a ditzy airhead when it suits him (such as to avoid work or going into battle) [25] [26] and an intelligent manipulator.
His predictive skills allow him to adapt and prepare for potential situations, such as preparing blood bags before getting beaten up by Magma. [27] These skills also allow him to choose the best path for negotiation, such as openly offering to lie to Tsukasa about Senku's death to earn his favor, [28] pretending Senku had a gift for Minami to obtain her Revival Fluid , [29] , and tricking Ryusui into paying them for the privilege of being on the hot air balloon despite needing his expertise anyways. [30]
He tends to act self-absorbed and perverted, as seen when he considered sticking by Tsukasa for the purpose of having a harem, hitting on Kohaku , and later Amaryllis , [31] though he gives off a gentlemanly air even when being honest about such. While he frequently portrays an aura of selfishness, hard self-interest, manipulation, and deviousness, Gen is a good person who can't bring himself to harm others. His outward appearance is masked by his mastery in psychology, but his actions speak of loyalty, determination, kindness [32] and even sacrifice at times.
He is good with people of all ages, Kaseki being one of his cherished people whom he spends a lot of time with as Kaseki enjoys his aid. [3] He also gets along with Suika and together they succeeded in protecting the village. [33] In addition, he is also quite genuine in his admiration of others, respectfully recounting Lillian Weinberg's renowned singing skills to the people of Ishigami village in reverential tones.
Gen is also rather quirky, frequently hamming things up as if it were a performance and can often be seen speaking in playful Pig Latin . This comes out most prominently when he's surprised or shocked. [34]


Dr. Stone

Genbu is a very tall man with long, dark hair which he wears swept back. The ends of his hair appear to stick out in wild tendrils. He has a long goatee that is tied at the end with a small piece of rope. He wears the village rope around his waist, where it holds two knives similar to the ones Kohaku uses. His features are sharp, with steep eyebrows and visible cheekbones. His neck is also much longer proportionally than most of the other villagers' necks.

Despite his grumpy portrait, all of Genbu's depictions show him as jovial. He also accepts Senku as the new Village Chief without too much discussion, but it could just be eagerness to have an excuse to party.


Dr. Stone

Ginro is a rather short, androgynous young man with medium-length blond hair that covers the left side of his face. Unlike his brother, he seems to take strongly after his mother in looks, having round, green eyes and soft facial features, and unlike many of the other warriors, is not very muscular. Due to these traits, he is able to convincingly pass himself off as a girl and uses this in conjunction with a disguise to (reluctantly) join the harem selection and infiltrate the Petrification Kingdom . According to Matsukaze, he resembles his former lord, who is said to be a distant relative. [9]
Ginro wears a blue karate gi-like uniform and belt. He, like his brother Kinro, carries his spear wherever he goes.

Ginro is the coward [10] of the two guard brothers, immediately showcased when he gets visibly more startled than Kinro by Kohaku's threats of attacking them unless they let Senku into the village. [11] Another example being when he considered the possibility of having everyone run away from the village to avoid a fight with the Tsukasa Empire , though after Kohaku points out that only a scum bag would consider it as the elderly and children wouldn't be able to keep up, he claims he didn't think of such an idea. He can be very full of himself and is selfish, such as when he abruptly decided to try and beat Senku in the village games and take the spot of village chief. He's easily distracted by shiny things and Senku's antics, which ends with him usually working to further the scientist’s schemes. [12]
Another aspect of his personality is that he is much more sincere in his cowardice and is open about his feelings, showing no hesitation to admitting to being scared of things like soap bubbles, bugs, and poison gas. His sincerity is something he seems to be aware of and he finds lacking in other people, he questioned Senku and Chrome acting so fearless in what could easily be a fatal mission , which he describes as being reckless until being comforted and corrected by Kaseki , who's also shown to be open about his shortcomings. He's also tried to pass this sincerity onto his brother, suggesting early on that he should tell Kohaku about his poor vision so she wouldn't treat him so harshly about his deficiencies in fighting because of it.
There are two main sides to him: a kinder, gentler side that cares for his friends and family, and a scummier side to himself. There are times when his scummy meddling side wins over his nicer side, such as when he enters the village tournament to determine who would be village chief and wed Ruri . While he initially does so to protect Ruri from Magma , once he learns she is satisfied with marrying whoever wins, Ginro immediately decides to win so he can be chief and order people around, have ramen everyday, give everyone a harem, and be a "good chief," in his own words. The villagers are so disturbed that when he loses to Senku, they immediately cheer, despite the fact they do not approve of Senku as an outsider. Similarly, when the Perseus sets sail, he refuses to board for fear of such a dangerous journey, though he pretends to swim after the ship in order to impress some girls. In addition, he tends to enjoy meddling in Chrome and Ruri's relationship. At one point, in an extra, he even suggests that he, Chrome, Kinro, and Senku attack Kohaku together to see who is stronger and claims it is "fair" since Kohaku is much stronger than all of them individually. [13]
Ginro shows regret for his cowardice often and genuinely cares about his friends, to the point where he runs off to help Senku and Chrome in a dangerous situation where they were attempting to acquire sulfuric acid from Sulfurina , a natural sulfuric acid spring located inside a crater where highly poisonous gases accumulate. Similarly, he refuses to cut the bridge leading into the village despite knowing that doing so would block the entrance to Hyoga 's forces, because his brother Kinro, who was wounded and hanging from the bridge, would have to be sacrificed. Later on, when his brother faces the prospect of being petrified, Ginro manages to overcome his fear to protect his brother with help from Suika. This proves that despite having a scummy, cowardly side, he will endure any tough situation to protect his friends and family. He also showed this when he received great information on the Leader of the Petrification Kingdom, after which he was mortally wounded by Ibara. He was willing to accept his fate after Kohaku saved him.
He can be lazy, as he tends to slack off during his duties as a guard. He often complains when he and Kinro have to lend manpower to Senku's inventions, which physically exhaust them, and celebrated alongside Kinro when Senku built a power plant that would decrease their work.
When it comes to romantic affairs, Ginro is shown to be focusing primarily on a woman's superficial qualities, a trait his brother Kinro greatly despises. [14] Though he's never been shown involved in any romance of his own, he ranks high in the top village hunks according to the village girls. He can get very nosy about other people's romantic affairs, aggressively inquiring while under the impression that Senku was about to discuss the type of woman he likes when he expressed some intrigue about Homura , who was spying on them. His intrusions in other people's relationships don't always lack tact or common sense, however, such as when he suggested that Chrome should use the first ever telephone call in the stone world to confess his feelings to Ruri, an idea that several people seemed to back, and they were visibly disappointed when Chrome didn't go forward with it. Previously, he had taken the chance to quietly comfort Ruri during the village games by assuring her that Chrome was going to win, saying he could tell she wanted him to be victorious (and therefore become her husband); this lasted a short time before his ambition took over and he attempted to win himself.
He also shows a perverted side, imagining what it would be like to marry Ruri, and also fantasizing about the "forbidden love" that would be Ruri marrying Kohaku, her sister. He showed interest in the use of an x-ray to peek under women's clothes during the construction of the Perseus, and towards the end of the Treasure Island Arc, he got himself distracted in contemplation of Kohaku's breasts while in the middle of thanking her and others for saving his life. Similarly, he enjoys showing off, particularly in front of cute girls, as he imagined himself looking cool while facing off during the village tournament, though in reality, he was beaten badly before winning. He similarly swam to the Perseus to make it look like he was brave and wanted to join his friends on their dangerous journey to the outside world when, in reality, he believed he would not be able to reach the ship and would return to the island looking like a hero and getting several girls to like him.

Hagane is a man with thick untamed eyebrows, downturned eyes, short spiky hair, and a wide jaw with a very pronounced mentolabial fold. His hairline is a pronounced 'M' shape like many of the male villagers, possibly indicating slight balding.
He wears an outfit similar to Magma 's: a dark blue shirt with a V-neck and cropped pants of the same colour. He has rope tied around his waist.


Dr. Stone

As noted by Ginro , he looks nearly the same as his son Soyuz , but with the key difference being that he had hair on his head, a beard, and had no scars. [1]

Dr. Stone

Homura is a short and thin young woman with long pink hair, worn in a high ponytail that sticks upwards, reminiscent of a bouquet of flowers. Her bangs curve around her face, with the longer strands ending at her cheekbones. She has sharp red eyes, small pink eyebrows, and full lips, and she's usually expressionless. Her face is very round. Homura's petrification scar is a jagged line originating from her groin down her thigh, ending about halfway.
She wears a pink paneled dress with a white fur trim along the boat neckline. The dress is split into four segments, beginning just below her breasts, tied closed around her waist with string but left open below that, exposing her thighs and hips. Her shoes are tall thigh-high boots of the same pink material that her dress is made of, the tops and bottoms of which are jagged and open like petals on a flower. There is a black seam running down the front of them all the way from the top to the tip of her toe. The soles are made from a similar material to the Ishigami villagers' shoes, but Homura's heel is entirely at the front, forcing her to walk on tip-toes.
She also has a small brown leather backpack that contains fire-starting materials for arson purposes. A few long sticks jut out the sides so that they're accessible at all times.
Following her second revival, her scar has disappeared.

Homura possesses a strong loyalty towards Hyoga to whom she has been implied to have romantic feelings for. She will complete her task regardless of how arduous it is, such as watching over the Ishigami Village by herself. She is cautious, observant, and intelligent, managing to remember the names and faces of all the villagers during her lookout. When she noticed Chrome, Magma and Gen were gone, she was able to quickly figure out since Gen (who had no physical strength or scientific knowledge) went with them that it meant he would be involved with negotiations and that the three were heading to the Tsukasa Empire. She also demonstrated caution when Senku offered her cotton candy, though relented and ate some.
She proves to hold great intelligence as she is hard to trick or track, managing to notice the tungsten Senku smeared on her to track her and washing it off along with trying to tire Kohaku out by talking while she was chasing her so she would run out of breath. She often maintains a cool composure, rarely getting flustered even when captured or held hostage. She is rather competent and can be merciless like Hyoga, at one point managing to burn the entire Ishigami Village while Hyoga and his forces distracted them. However, Senku suggests that she is not fully evil and can be converted to their side with enough effort (though so far it hasn't been successful as she is still loyal to Hyoga).
After Hyoga is revived to teach weapons training, he asks that she be revived as well. While she remains loyal to Hyoga, she now also works for the Kingdom of Science, as he does.
On a side note, she has a soft spot for sweets, as she ate Senku 's cotton candy despite being wary of it and, in chapter 155, seemed quite tempted by the sweet smell of vanilla.


Dr. Stone

Hyoga is a tall and fairly built young man with short, loosely hanging white hair. For unknown reasons, he is seen squinting most of the time, though in the rare instances he isn't, he's seen to have sharp, dangerous looking eyes. Under his mask, he's also shown to have noticeably full lips.
He wears bird feathers around his neck, tan gloves, and a black mask covering his nose and mouth because of his terrible de-petrification scar. He goes shirtless, though wears a long black cloak that covers most of his midsection, and dons a baggy grey warrior-skirt with an elaborate white sash tied around his waist to act as a belt. Unlike many from the Tsukasa Empire , he wears shoes as well- tan colored knee high boots that match his gloves.
Upon his second revival by Senku, the scar on his mouth was completely healed. [8] He did not repaint his scars. [9]

Hyoga has an easy going attitude towards everything. Even in situation that do not work in his favor, he still remains calm. When Gen betrayed him, Hyoga did not seem bothered by it even though his weapons were destroyed mid-battle. While he claims to share the same values as Tsukasa when it comes to only reviving the young and creating a community where no one takes from others, Hyoga himself is an elitist who believes in social darwinism. He categorizes humans as either enlightened (or strong) and unenlightened (or weak). He believes that the "brainless incompetent masses" should not be allowed to live and that only those who excel should be allowed to live. While he does follow a form of social darwinism, he does not believe it is only the physically strong who should survive, as he wanted Senku to join him in his endeavors and become the strongest duo, indicating he respected Senku's intelligence and understood his capabilities. He is very manipulative and cunning, managing to hide his desire to murder Tsukasa and usurp his title as strongest primate by working alongside him until he found a weakness. He seems to be observant, managing to instantly tell that Kinro has bad eyesight simply from seeing Kinro squint. He is cruel, merciless, and uncaring, having nearly murdered Tsukasa right after he reunited with his sister as she became a weakness and he knew Tsukasa would do anything to protect her. Even before that, when he chased Senku and his friends, he and his troops reached an area full of sulfur gas. He kicks his subordinates down into the ground where the sulfur was to "test" and see how dangerous the sulfur was, not caring for their lives. When Tsukasa laments their deaths and names them, Hyoga does not even show a hint of remembering who they were until Tsukasa pointed out they were the ones who died by the sulfur gas. He had earlier shown contempt for his underlings, referring to them as mush brains and frequently insulting them and considered them little more than disposable pawns. He tends to refer to things as being done "properly" or not.
Despite his lack of care for those who he deems "useless" or those who oppose him along with having a strong Darwinist belief in only the strongest deserving to live, he does have a few good qualities. He genuinely respects those who he feels does things "properly." He recognized Kinro's strategy of staying onto the bridge as the number of Tsukasa's forces were disadvantageous and fighting on the bridge would force the battle to be one on one. Similarly, he genuinely respects Homura and puts complete faith in her abilities, referring to her as the only underling who did things "properly." Also, he deeply respected Senku and wanted him on his side enough so that even when Senku refused, rather than kill him, he wanted to torture Senku into agreeing. Later, by chapter 132, he has softened his view so that rather than outright eliminate the statues of the people he deems "worthless," he would simply let them stay statues. In addition, he agrees to side with Senku rather than Moz because he realized Moz was an unworthy untrustworthy harem seeker who only valued beautiful women and not people based on strength, abilities or intelligence. He even places faith in science and Senku, and his faith is well placed.
After his third release from petrification, Hyoga seems to have become a loyal member of the Kingdom of Science, requesting that Homura and Moz be depetrified to confirm his alliance. He even appeared to make bygones with Tsukasa after the latter wanted him to help with training.


Dr. Stone

Ibara is an extremely tall and muscular middle-aged man that stands at almost double the height of Kirisame . He has a thin face with sunken cheeks, a prominent nose, a thin, twirled mustache, and a long goatee tied near the end. Triangle-patterned tattoos run along his body, from the top of his head along his spine to the fronts of his shins and feet. Similar to Soyuz and his father, he has larger-than-average earlobes.
He wears a white robe with a stone or metal collar, tied at the waist with a dark sash. He wears two stone pauldrons with spikes around the top edge of them and a similar-looking hat. His shoes are heavily platformed and add a lot to his imposing height.

Ibara is merciless and manipulative, only caring about what he himself stands to gain. He is paranoid due to him hiding the secret that the true leader is petrified and as such is swift and cruel in dispatching threats. Despite his paranoia, Ibara's true nature is a dark, scheming persona that gives off a terrifying presence.
He does not value his followers, no matter their loyalty, as shown when he wanted the entire island petrified despite his own people on it and even petrified Kirisame once his evil nature is exposed. He occasionally takes risks, such as when he petrified the whole island under the assumption that the Kingdom of Science had more revival fluid . [6] Additionally, Ibara seemed unworried about the truth about the head being revealed upon his own defeat.

Ibara's first appearance.

He is also a pervert, grabbing women for his harem and claiming them as his "reward" for all the hard work he has done, despite obvious protests. In addition, he tried to grab Kohaku to feel her up and almost had his hand snapped by her before Moz intervened, [7] and later to supposedly teach Ginro about love before "satisfying" the master. [8]
Ibara was the one who created the rule to not make new things, as this would allow the islanders to fight back and kill him; he additionally forbade leaving, knowing full well that he would end up dying alone as most of the islanders despise him. He is also callous and an "ask questions later" type. Upon finding the boat belonging to the Kingdom of Science off the shore, he has them petrified, despite it being obvious they weren't from the island and stole their supplies and clothing. While he deems science as sorcery, he can be very cautious when dealing with it, as he quickly deduced Moz allied with the invaders after spotting an earpiece and later fled upon seeing Hyoga revived.
Ibara enjoys battle, as while an initially angry Senku ran from him, he realized he was actually setting a trap. He is not above giving his enemies compliments, as he was impressed by Senku's plans.
He displays his cruelty when he shows no remorse or hesitation about murdering infants. Even though he enjoys using the Medusa device, he is still fearful of its power being used against him. When Senku attempted to use a phone to activate the Medusa device, he quickly discarded it in fear, although the device failed to activate due to not being close enough to the source of the voice command. He takes great pride in his intelligence, thinking about how he is always cautious. He also believes that those who are arrogant because of their intelligence are the first ones to fall, which is ironic considering he clearly thinks highly of himself, which Senku reiterates back to him when the former outwits Ibara before finally petrifying the evil minister.


Dr. Stone

Jasper has mid-length white hair and a small black goatee. He has a long, straight nose and a stern expression. He wears a piece of rope tied around his neck and wears dark green clothes.

Jasper is a calm and soft-spoken man. He is very loyal to the village and as such is tasked with guarding the village's priestess, Ruri . As with most villagers, Jasper is wary of Senku at first, but eventually comes to accept him as an integral part of the village.


Dr. Stone

Joel is a young man with a bowl cut and two errant hairs sticking out of the top of his head forming a '12'. His eyes are white with no visible pupil, almond-shaped, and have dark shadows underneath. They are also mostly hidden by his bangs. His eyebrows and nose are both narrow. His mouth seems quite small, with no visible lips.
His outfit is heavily clock-themed, consisting of a graduated collar with a set of heart-shaped clock hands dangling down the front, a black long-sleeved shirt with '9' on the left arm and '3' on the right in swirled writing, and a white apron with side pockets and a '6' on the front in a similar font. The numbers along with the clock hands on his chest creates a simplified clock across his whole body. He also wears black pants, shiny leather shoes and has a watchmaker's loupe (magnifying eyeglass) strapped to his head. Upon arrival at the American Colony 's base, he made himself a watch to wear as well.

Joel is very confident in his abilities, showing great pride in himself. He believes a man who minds his time should always wear a watch as it's proof of good taste. He prefers to work in silence, albeit without a desk, squatting on the floor.
Depending on who he is interacting with, Joel's mannerisms change drastically. With women, Joel is very shy and stutters, not saying much. This is because he spent his whole life working and never learnt how to act around women. In contrast, Joel is quite rude, cocky, and verbose when interacting with other men, showing them no respect whatsoever. However, he will show respect to fellow artisans as he wanted to share a toast of wine with Kaseki over the success of their mission.


Dr. Stone

Kaseki is a short old man with a large, white beard. He's completely bald, with bushy white downturned eyebrows that get thicker towards the ends. His eyebrows normally cover his eyes, leaving only shadows visible. He has a large, bulbous nose and slightly pointed ears. Marks of age cover his face: forehead creases, bags under his eyes, crow's feet, and smile lines.
His outfit consists of a brown tunic and hood, similar to a Christian monk's habit. He has a pouch tied around his waist with his craftsman's tools held at the front. Like the rest of the villagers, he wears white platform sandals.
Although initially appearing to be frail, when fired up, he bursts through his clothes, revealing a muscular body. This transformation usually results in him wearing only the lower half of his outfit and showing off the village rope that is tied around his neck. During this transformation, his eyebrows furrow and tilt upwards, flaring at the ends, and leaving at least one eye visible.

Kaseki is an honest older man who is prideful in his work and skill as an artisan. Unassuming unless provoked, he displays boundless energy when excited about his work.
Originally wary of Senku , Kaseki quickly becomes a loyal and prominent member of the Kingdom of Science . His love for crafting since his childhood helps him form strong bonds with advocates of science. Having been relatively isolated for much of his life due to his interests, he now considers Senku and Chrome as close friends, despite their age differences. [14] He is alike to them in the fact Kaseki is passionate about his craft and despairs when it fails.
A genius craftsman, Kaseki picks up techniques with little effort. Upon seeing glass for the first time, he immediately understood how to work best with the material. [15]
Kaseki, as one of the oldest members of the Kingdom of Science, is relatively wise. He often imparts wisdom on the other members and is unafraid to admit his own shortcomings. [16]
Despite his pride, Kaseki often seeks external validation for his work, particularly from women. [17] [18]


Dr. Stone

Kinro is a muscular young man of slightly above-average height with brown hair, green eyes, a scar on his right cheek and a lock of long hair that hangs between his eyes. He often has a scowl on his face partially caused by his nearsightedness.
He wears a sleeveless royal blue karate gi-like uniform with a rope belt. On his back, he wears a buckler emblazoned with the village's star pattern.
After the tournament to determine the chief of Ishigami Village , Kinro begins wearing a pair of glasses to correct his nearsightedness. He also carries a katana strapped to his side after Hyoga's raid.
When Yuzuriha built a fashion store, Kinro wore a modern outfit. [11]

Kinro is the stern half of the two guard brothers. He takes his job seriously and is not easily distracted. He believes in hard work and despises laziness or cheating of any form, even if for a noble cause, such as being the only one against entering more of their allies to fix the Village Games so the Kingdom of Science would win despite them needing to win in order to cure Ruri .
He's dedicated to upholding the rules, refusing Senku's entry into the village, despite him saving Kohaku 's life. [10] [12] He maintains his principles even when a huge portion of the village gets bribed by Senku's ramen, vehemently refusing to participate in any "sorcerous" activities or try "sorcerer" food. [13] In the village tournament, after using Suika 's eyeglasses made by Senku to fight against Magma , he consults with Jasper about the mask's legality, feeling as though he unfairly cheated. Though initially suspicious of Senku [14] , he becomes a loyal member of the Kingdom of Science, vouching for Senku to the rest of the village. This also proves that, despite his adherence to rules, he is not prejudiced towards others and is capable of seeing the good in them.
Kinro's reasoning skills are a bit poor in the beginning. He refused to believe there was life outside the village aside from those banished. Plus, he overlooked the fact that it would be impossible for Senku to be a banished person as he is similar in age to him and never met him before. Again, the rule wouldn't apply to those descended from those banished as they didn't commit crimes towards the village.
In addition, he proves that, despite being a "stick in the mud" most of the time, he is genuinely loyal to his friends and is dedicated to his duty as a guard, especially in protecting the other villagers. When Kohaku asked for his help in winning the grand bout to help her sister, he was perfectly willing to help. He also often helps Senku with his man-powered generator by utilizing his labor, though is happy when it becomes automated and he doesn't have to work himself to death on it anymore.
When the village is attacked by Hyoga and his forces, he is willing to sacrifice himself by having Ginro cut the bridge that holds him and Hyoga's goons to ensure they cannot harm the village. Even when heavily injured, he immediately goes back to guard duty the next day as he feels that, as the guard, he shouldn't lay around and use his injury as an excuse to shirk his duties (though his injury was serious and definitely needed more than a day to heal). He is straight-laced to a fault and tends to act as Ginro's conscious to motivate him.
Prideful to a fault, he refuses to disclose his "blurry eye disease" even though it puts him at a severe disadvantage in combat. [15] After being frightened by Senku's soap bubbles [16] , he claims that he was merely reacting cautiously to the unknown. He tends to react mostly stoically to most things and does his best to keep his calm at all times.
Despite his serious temperament, Kinro often acts emotionally. Senku successfully bribes Kinro into letting him pass by gilding his spearhead. Afterwards, Kinro shows a strong emotional attachment to the spear. [17] He often gets annoyed and worn out by Senku's experiments at his expense. After Senku creates a generator that eases his work, Kinro is excited, despite his normal disdain for laziness. In addition, he is genuinely excited by the automobile Senku makes alongside the other guys. When Minami hinted at a possible attraction of his to Kirisame, he became nervous and could only vouch for her skill. He values less shallow qualities in a woman compared to Ginro. [18]
Kinro seems to be manipulated easily, likely due to his purity and honor. Gen Asagiri made use of this when he manipulated Kinro into eventually helping Senku power an electricity generator. [19]
As a member of the Kingdom of Science, he learns to overcome some of his stubbornness. Initially dismissing arithmetic as unnecessary and impractical for combat, he is quick to join Senku's literacy school, telling Ginro that learning to write is an increasingly important part of communication.


Dr. Stone

Kirisame is a slender woman comparable to Kohaku in height, with black dreadlocks and caps at the tips. She wears stone ornaments in her hair, similar to cat ears in shape. She has narrow, green-colored eyes and is usually expressionless. She has facial markings of unknown origin that extend from the top of her eyebrows in a curl, similar to Moz's.
She wears a loose, light green see-through dress. [10] Kirisame maintains her modesty through bulbous ornaments that cover her chest area and a dark blue feathered design that covers the front of her lower half. Amidst the stone ornaments is a red pouch with a yellow star on the bottom for carrying the Medusa . On her back, she has another Treasure Island star design with the black braid hanging down that functions as a hook for her twin clubs. She also wears a necklace that covers most of her neck made of stone.
As a child, she looked similar to her current appearance but her hair formed two little bug antennas. [11]

Kirisame is a cold, collected individual who, unlike her colleague Moz, appears more professional, rarely smiling or relaxing, coming off as unflappable. However, she occasionally shows cracks in this personality, for example, towards romance. When Kohaku kissed Senku under the pretense that he was her boyfriend, Kirisame was incredibly flustered. She also blushed at being hinted to have an attraction to Kinro .
Like most Stone World people, she is amazed by new things, such as her own revival and the sights of the sea.
Kirisame is loyal to the head of Treasure Island , unknowingly committing evil in his name due to Ibara 's wicked manipulations. After learning she had been duped into unjustly petrifying the islanders for years, Kirisame was angered.
Since accepting Soyuz as the leader of Treasure Island, Kirisame has noticeably mellowed out. She joins the Kingdom of Science on his request, following Senku's orders. She seems to get along with her new allies, never seen in conflict and having casual conversations.


Dr. Stone

Kohaku is a young woman of average height with a slim figure. She has a delicate face, blue eyes, and blonde hair tied-up in a spiky ponytail.
Her appearance is that of someone who appears to be a mixed heritage of American/Japanese, [16] denoting her as the descendant of Byakuya Ishigami and Lillian Weinberg . She shares a strong resemblance with her older sister, Ruri, but has wild hair in comparison to her sister's soft, flowing hair, and a slimmer body.
Her most typical attire consists of a V-neck, sleeveless and short navy blue dress. Underneath she wears makeshift garments akin to a bra and a fundoshi (traditional Japanese garment). The dress is tied with a rope tied in the middle, and uniquely shaped stone sandals. She also wears a tan ribbon as a choker around her neck, which resembles the one worn by Lillian as well.
She has a different fur dress and footwear for the winter, and occasionally takes on different outfits, either for functional reasons (such as the dresses she wore in Treasure Island ) or out of her own volition, such as the party dress she wore while helping Senku gamble against Ryusui and Gen on the trip to America.
Her wooden shield is eventually replaced with a metal lined one made by Senku. [17]
In Dr. STONE: 4D Science , she cuts off her ponytail, giving her short hair for a while, but it grows back almost immediately.

Kohaku is a kind young woman, willing to put her sweat and tears, as well as her own life on the line to protect those she holds dear, taking rigorous care of her sickly older sister, and even willing to participate in the tournament for her hand in marriage just to protect her. She purposefully lied and took a scolding in order not to reveal she was attacked by Tsukasa, as not to distress her sister and the villagers. [18]
She is just as caring towards her friends and comrades, being particularly dedicated to Suika , playing for her the role of an older sister herself.
Furthermore, Kohaku is always attentive to give emotional support to people going through hardship in general, such as Mirai upon the loss of her brother. [19] She can sometimes be seen thoughtfully worried for people, in which cases she tends to sit down with her arms around her thighs, if there is nothing more she can do to help.
On her flip side, she tends to be extremely cautious or even threatening with people who haven't earned her trust. Gen was subjected to this for a rather long period of time, with multiple threats on his life from her, and even Senku found himself in a similar standing early on. After he interpreted her words as her confessing to having a crush on him upon being rescued, she would not dare fall asleep near him without her knives firmly grasped. [14] It should be noted that if she feels safe instead, she will fall asleep basically anywhere and in any situation.
To further complicate the matters, she has a choleric and impulsive personality that makes her burst in rage or carry out reckless actions if provoked, which could potentially lead her into fatal mistakes. While she could be daring in general, usually it took some rather specific scenarios to send her on a blind rage, most typically having her friends be captured by an enemy.
People such as Senku, Gen and Kokuyo have made attempts to wrangle these uncontrollable reactions, with varying degrees of success. Despite their efforts, she makes little to no improvement; however, as the story progresses, she encounters much fewer of the situations that would have pushed her over the edge, as she spends most of the time not separated from her group of close friends.
In less dire situations she is able to make conscious decisions, [20] but that can still go poorly given the parade of new dangers she doesn't understand, either from unexplored nature [21] or new people, as well as her own subjective decisions informed by her strong sense of justice and bad temper. This volatile combination tends to bring her into dangerous situations such as her battle with a more competent fighter like Tsukasa, whom she decided to attack after witnessing him taking Yuzuriha hostage and then killing Senku, not being concerned with whichever motives he might've had. [22]
Despite how violent she can be, Kohaku has admitted that she could not bring herself to kill a person, and if she were to do it, she would have to do it under orders, diminishing her responsibility in the act. [23] This is not without precedent, as whenever she threatened to explicitly kill someone prior to this admission, it could be observed that she often sought the approval of someone else. One example was when Gen admitted to be a spy for Tsukasa, she asked Senku if she should dispose of him. Prior to this, when Gen first showed up at the village, she instead shifted the decision onto Gen himself, by leaving up to him whether she should kill him or not, based on his choice for his next move. [24]


Dr. Stone

Kokuyo is a large, muscular middle-aged man with blond hair tied into a ponytail. He has gruff, hardened facial features with thick eyebrows, a large nose, and intense brown eyes. His long brown beard and goatee notably do not match his blond hair, and for clothes, he wears a blue robe with a white undercloth with a rope tied around his neck.

Initially, he is a harsh man who threatens to disown Kohaku as his daughter for constantly going against him, such as entering the village tournament and winning to prevent Magma from becoming the new chief and marrying Ruri or bringing an unknown figure to the village. [7] He also didn't seem to mind Magma being the new chief, despite knowing that he didn't care for Ruri's well-being. However, he does care for Ruri, as he worries for her health. He seems to want to become closer to his daughters and becomes saddened when they don't reciprocate. For example, he gave Kohaku her shield, and when Senku suggested using it in one of his inventions, he shyly remarks that he is fine with it as long as Kohaku is, but clearly expects her to reject it. He is saddened when she shows no sentiment towards the shield and quickly uses it in the invention. He seems to later reconcile with Kohaku, as he realizes how hard she worked carrying water for her sister every day to delay her illness.
He is wary of outsiders, especially Senku [7] [6] , but later grows to accept him and states that making him the leader was not a mistake.
He can be simpleminded, believing the tungsten that Senku brought was for throwing at enemies and not realizing that he was going to use it for an experiment. Ruri and Kohaku claim this is because he came from the older generation. Despite his practical and initially simple view of the world, he develops an appreciation for the comforts that the Kingdom of Science has brought to his village and its people. He praises Senku for not only being an effective leader and worthy successor but also for being someone who has brought out a crucial element for survival: fun.


Dr. Stone

Kujaku is a woman with dark lips, and sly, almond-shaped eyes. Her hair is styled into a short a-line bob, with two longer segments at the front. Her eyebrows are quite thin, s-shaped with a slightly rounded head that tapers towards the end. She has an air of mature elegance.
She wears a long, navy-blue, tube-top style dress with no sleeves that exposes her collarbone. The top of it flops over slightly, showing the brown underside of the leather. She wears the village rope as a belt around her waist.

Kujaku is quite composed but happy, usually sporting a slight smile and tends to chuckle a bit before saying something (for example, " heh ... It could be that one of those countless stone statues was revived." [3] ). This could be because almost all of what she says is a funny comment of some sort.


Dr. Stone

Leonard is a tall, sinewy man with a rather severe expression. His face is gaunt with deep cheekbones. He has large but narrow eyes with very small pupils in the shape of a PPI radar display . He has a large hooked nose with thin lips and a fairly deep mentolabial fold. He does not have eyebrows. His hair is long and wiry, fanning out in black dreadlocks away from his face, with his hairline accentuating the jagged lines of his petrification scar. The scar itself is similar to the shape of his pupils, two concentric circles centered on his glabella with mostly-symmetrical cracks coming from the outer circle at the positions of hours on a clock face.
His outfit is consists of a black, skin-tight, short-sleeved shirt, black gloves, baggy black pants, a wide belt, a skirt with the American colony's particular zigzag hem, and white boots that reach mid-shin. He also seems to have two black bands above his biceps matching his T-shirt, possibly indicating that he's wearing it off-the-shoulder. Like the rest of the Stanley 's squad, he's also got oversized metal shoulder pads with tassels draping over the top of his torso. Below it, he's also got the zigzag metal collar.
After his revival, Leonard loses his petrification scars [4] .

Leonard is serious and dedicated to his job as the main operator of any communication equipment for Stanley's troop. He is extremely vigilant, making sure he doesn't miss any radar activity and keeping a constant ear on the radio waves.
He answers most questions bluntly, directly, and informatively, befitting of a trained soldier. Despite that, it's still possible to get his façade to crack: the sudden increase in speed of the motorboat the scientists were escaping on caused him to be unable to finish his sentences properly [5] and most unexpected things they've done have caused him to raise his voice in alarm. [6]


Dr. Stone

Lillian was a beautiful young woman with long blonde hair, tied into a ponytail with a ribbon. She shares a strong resemblance to Kohaku and Ruri, as well as many of the women of Ishigami Village, denoting her heritage as their ancestor. Whilst on the ISS, she wore white-striped trackpants, like her fellow astronauts, and a black tank-top.
After spending 3 years on the island, most of Lilian's clothes had fallen apart, leaving her in a makeshift sleeveless shirt, shorts, and going completely barefoot.
Eventually, Lillian was left in a makeshift tan dress of sorts and continued to go barefoot.
Based on her appearance and her last name, it can be assumed that she is likely of German descent.

Lillian's full appearance

Lillian was a kind and shy young woman. She showed a bit of a playful side as well, as she briefly pretended to be a typical diva while aboard the ISS, but quickly revealed that to be just one of her jokes. [4]
She was a profound lover of music, having mourned the loss of centuries of collected compositions ranging from classical works such as Mozart to rock music icons like The Beatles. Music appears to have been a pathway to her escape from an alcoholic father. [5] From the beginning, she was a firm believer in Byakuya's belief in the importance of fun and entertainment as being crucial to the survival of humanity. She revealed to Byakuya that she wanted to unite as many people as she could in happiness with her talents, displaying a passion for the power of music over the human mind and heart.
Her conviction in this belief transcended her lifetime hundreds of times over as her belief in the power of the human spirit inspired her to help Byakuya write The Hundred Tales which helped her descendants to survive and maintain the flame of civilization. Her faith in humanity paid off, as Byakuya's son Senku would be remembered in legend and eventually come to Ishigami Village to lead humanity out of the Stone World.


Dr. Stone

Luna is a curvy young woman of average height who has wild, short hair with a few locks long enough to cover her left eye. She has a small bust and broad hips and is considered to be very attractive by Carlos , Max , Moz , and several others.
For clothing, she wears a striped, form-fitting short backless dress and a choker with a star on it. She also has a pouch wrapped around her left thigh and a pair of thigh-high boots with heels. Her petrification scar takes the form of a star-shaped on her lower back.

Not much is known about her, though she is shown to be quite timid.
Luna seems to have a disposition against murder, as she questioned Stanley if he was really going to kill someone. However, she was silenced by his glare and proceeded to support him in his endeavor. Even when given a perfect opportunity to get a clear shot, she went so far as to make herself look like a fool to divert Stanley's signal.
A hopeless romantic, Luna often fantasizes of marrying and living an easy life, a habit she had even before her petrification. She later mentioned that her type of man is an intelligent, hardworking man with conviction to match. True to word, while she believed Taiju to be their head scientist, she didn't feel attracted to him but instead felt attracted to Senku.
Despite being asked to find out which passenger was Dr. Taiju, she came up with a romanticized version of him that didn't fit him and didn't notice he wasn't the scientist after interacting with Senku, who made no qualms about hiding his intelligence when he used science to make soft serve ice cream to tempt her. However, she has slowly become suspicious of him after hearing of his association with Xeno. After she officially learns Senku is the scientist, Luna helps tend to his wounds and asks him to be her boyfriend.
While Luna often comes off as snobbish and air-headed due to coming from a wealthy and influential family, she is not one to rest on her laurels and prefers to earn her place. She is shown to have great persistence, being displayed to have great diligence in her medical school studies, even repeating courses she failed instead of bowing out.

Magma is a large, muscular man with slicked-back blond hair that brushes the top of his shoulders, with a single lock falling in front of his face. He has thick, pointed eyebrows that are usually furrowed. His chin is prominent and he has a strong jawline. His physique is thick and muscled, significantly more than any of the other villagers, only rivaled by Tsukasa and Hyoga 's henchmen.
His usual clothing is a dark blue tunic with short sleeves that displays his voluptuous chest. Underneath, he wears very dark-colored pants that are tied around the ankle. Like most villagers, he lacks accessories, however he has two bracelets made of brown-leather thonging on his wrists. He wears the village rope around his waist as a belt. During the winter, he wears a long coat with fur trim along the hems.
On Treasure Island , he temporarily wears a simplified version of his outfit: a dark open tunic, laced at the front with thick flat ribbon and a belt made of his village rope. Underneath, he wears a pale skirt/shorts to protect his modesty. His shoes are gone, but his bracelets remain. [10]

Magma is an extremely ambitious person aiming to become the chief of Ishigami Village. [11]
He is shown as being willing to kill to get his way when he attempts to kill Gen, believing him to be Senku . He also initially has paranoia of outsiders such as Gen and Senku, attempting to kill Gen partially because he believed he was a magician and that by eliminating him, he would remain the strongest. This also demonstrates his superiority complex, an obsessive need to prove himself to be the strongest.
He was shown to be rather gullible in the Grand Bout , falling for a trick Gen played on him pretending to have put a curse that would destroy his heart on him.
This would later be the reason behind his rivalry with Yo as both often compete with each other to prove who is better (especially between pre-petrification humans and post-petrification humans).
He also tends to be impulsive and acts before thinking, such as smashing the tungsten that he, Chrome , and Senku brought from the cave once he heard Senku mention he needed something out of the rocks (though he was in a way correct as Senku did need the tungsten smashed) and when Hyoga invaded the village, his first reaction was to attack him one on one without thinking about a strategy or teaming up with Kinro and Kohaku (as all three of them are the strongest fighters of the village and would have a better chance fighting together).
He tends to remark that when faced against a powerful opponent or army, they should simply slaughter everyone, proving his merciless nature and one track mind (without considering the disadvantages of such a strategy or a more peaceful alternative). He once even asked if they could simply smash the stone statues Tsukasa collected so they could dwindle their numbers and lessen the amount of people Tsukasa could revive for his army. This is seen again when going against the foes of Treasure Island. Magma is also sadistic at times, wanting Ruri to watch him hit Chrome over and over again, knowing that they have affections for each other. [12]
Despite this, he eventually cannot bring himself to kill Chrome and Senku. When alone with them in a cave, he chooses to save them from a cave collapse rather than use the opportunity to kill them. He claims that the inventions Senku makes are interesting and so long as he keeps making interesting things, he will not kill him. This is reaffirmed in a conversation with his lackey Mantle , where he states he still desires the village chief position, but not to murder Senku.
He even begins to willingly lend his help to Senku and similarly helps Gen set up a telescope as a birthday surprise for Senku. Also, despite being impulsive, seeing violence as the first and only solution, and charging into battle head first without thinking, he does have some tactical strategy. He can also genuinely admire and respect other people's abilities and strengths. As stated above, he does grow to respect Senku's intelligence and ability to bring new wonders to the village, which ultimately causes him to cease his desire to murder him. He understood and recognized Kohaku's strength. He also admired Kinro's strength and wanted him to be his lackey.
He even compliments and admires Taiju 's strong will and bottomless stamina and strength when they were farming. Similarly, he seems to grow a little, managing to recognize abilities beyond strength, such as Senku's intelligence, and he admires Gen's skills and even asks him to be his lackey, despite having once tried to murder Gen. [13]


Dr. Stone

Mantle is a man of short stature. His body is small in size, but big in belly, with visible chest-hair. In comparison to his small body, his head is huge, and its shape resembles that of a Chinese Buddha statue's. Mantle's face has baggy eyes with elongated eyelids. His hair is black and cropped short, and he also sports a beard.
Mantle's clothing consists of a ragged, green peasant tunic with a piece of rope acting as a belt. He wears a fundoshi that is on display too much of the time.

Mantle is a cunning, submissive, and devious man who is usually seen pandering to Magma's every whim. During the village games, he ties up Suika and lies to the Kingdom of Science that she is drowning in order to distract and disqualify Kohaku from the fights. [5] It's shown that he is very loyal to Magma, trying to help him acquire the position of chief in any way possible, such as throwing rocks and potentially injuring Kinro, who was having an edge over his boss. [6]


Dr. Stone

Matsukaze is a tall, young man with a relatively thin, but well-muscled build. His face is handsome and stern, and his black hair, which he keeps in a ponytail, extends to below his shoulders. He has a large crescent moon-shaped petrification scar on his forehead. He also has marking shaped vaguely like the Petrification Weapon on his left arm (which he carved in his arm when he was being petrified). [7]
Prior to his petrification, he wore a different outfit and lacked the scar on his arm and forehead. He also wielded a stone sword. [8]
Following his revival, he is given new attire by Francois . [9] He carries a wooden stick on his side like a sword, but it is later destroyed by Tsukasa [10] and replaced with a bamboo practice sword. [11] It was later destroyed by Stanley. [12] After his second revival, he lost his scar on his head. [13]

Matsukaze is an honorable, dutiful man. He is quick to thank Senku for reviving him, but immediately comes to the defense of Ginro (whom he believes to be his Lord at the time) when he appears to be in distress, and apologizes for his inability to protect him due to the petrification. Despite learning Ginro is not his Lord, Matsukaze continues to protect him, as Ginro is a distant relative. He will also apologize should he overstep his bounds, as he did so after he drunkenly asked Tsukasa to train him.
Like most Stone World people, he is amazed by new things, such as his own revival, the formula that depetrifies people, Senku's inventions, and the sights of the world.
He respects fellow warriors, humbly asking for a sparring match to see how his own strength compares. Upon Tsukasa 's revival, Matsukaze was willing to wait for sometime to allow the man to recover, showing that he does not wish to rush anyone should they need time to recover. He also showed himself willing to accept defeat after acknowledging the strength of his opponent.


Dr. Stone

Max is a young adult with a bushy hair and spiked nose. He is seen wearing a white coat and oval glasses, along with gloves.

Along with Carlos , Max seems to hold affections for Luna . He and Carlos are startled by Stanley 's intent on killing the enemies' science leader.
Carlos is shown to have great persistence keeping himself awake for thousands of years in order to serve Luna.


Dr. Stone

Maya is a very large, muscular woman with long, curly black hair, parted in the middle. She has long, thin eyebrows and large eyes, with thick spiky eyelashes. She has a wide mouth with full lips.
Her outfit consists of short dress with slits along the outside of both thighs, laced along the seams and a crisscross pattern covering the whole thing. It also has what looks like metal rings around the armholes and a jagged metal collar around her neck. She has two belts latched around the middle of her thighs. Her boots are high-heeled with a folded-over top and laced all the way up. Prior to the Petrification , Maya wore a suit during the DARPA expo.
When in battle in Araxá, Maya wears the standard uniform the other soldiers wear, seemingly acting as camouflage in the jungle, and she also now wears gloves. Maya now hones a sword in battle.
After her revival, Maya's outfit would see the addition of a belt around her waist similar to the two belts on her thighs, and she would wear the American standard zigzag-patterned uniform around her shoulders, much like the rest of the soldiers.

Maya is a boisterous and generally pleasant person. Whether it be friend of foe, Maya is not usually shown to harbor any ill will towards others, even apologizing to her enemies for winning the battle [10] . She has a very casual personality and even on the job will be laid back, often joking in the midst of battle. Throughout the series she has not been shown to dislike anyone, even helping the enemy at times, such as Matsukaze [11] , and she even made attempts to communicate with him, if it was to gain information. She would not harm others without a good reason; however, she will not hold back from doing her job as professional if the job requires it. She will not be your enemy unless you make her your enemy.
One of Maya's defining features is her love for singing. Despite being rather terrible. Maya will often speak in sing-song, indicated by the music note at the end of her dialogue, much like Gen . She will take any moment to sing, sometimes in victory [12] and other times to mark the start of a journey [13] . Maya's terrible singing has even been used as a weapon to stop people from hearing confidential information [14] . Maya seems to be rather oblivious to the fact her singing causes those around her great displeasure, and rather just enjoys herself.
Maya loves to eat, and is rarely seen without food in her hands. In her youth, Maya purchased so much food she went bankrupt, all with enough money to let her retire early. Maya joined the military on the condition that they kept her fed. Her favourite food is meat, and she is always seen eating chicken legs or even steak on the go. [15] [8] She has a seemingly endless supply of meat, perhaps coming from the cows at the American Colony, and after claiming ownership of the Perseus , she is seen with a bucket of chicken wings, perhaps to celebrate her victory [16] .
Maya has a great thrill for battle. Due to her status as the American Women's MMA Champion, showing she participated in many fights. Because of this, she can sense when an enemy is nearby and with a great grin on her face, welcomes the challenge. When Maya hears Tsukasa , a fellow MMA Champion, is her enemy, she gets absolutely thrilled at the idea, showing her love for a challenge. Maya has been shown to enjoy herself in battle, and has seemingly never faced a challenge in her life until Tsukasa, which is why she went all out against him, as she finally found someone who could match up to her [17] .
Maya seems to have a rather simple and dumbed-down outlook on life, similar to Taiju in that sense (ironic, considering they seem to get along the best). She spent all of her winnings, enough money to retire early, on food and went bankrupt, showing she has little grasp on the concept of money. When the military hired her, she accepted on the one condition they feed her indicating her true allegiances will lie with the ones who provide her food.
Maya does not understand science all that much. She is very much the brawn rather than the brain. When Xeno presented the brain wave charts at the DARPA expo, Maya was disappointed at the voltage level, showing her little understanding of science, once again similar to Taiju. When Xeno made everyone aware of the brain wave's significance, Maya was shown to be more shocked than her fellow soldiers, once again showing her little knowledge of science [18] . Later on the Perseus, Maya once again expresses her confusion over this scientific technology, but stated it doesn't matter as there are other folk who specialize in what she can't, recognizing her own faults. [19]


Dr. Stone

Minami is a curvy young woman of moderate height with very long, slightly wavy, blonde hair that reaches her hips. She wears a short grey headband that has two cone-shaped protrusions at the ends which are hollow, allowing her to hide small items within it. [9] She has large brown eyes, slightly pointed at the ends, and soft facial features. Her lips are thin and darkened. Minami is exceptionally well-endowed.
She wears a short paneled burgundy dress with short splits at the top of her thighs. It is both shoulderless and sleeveless, with a ragged top hem. A tan-colored ribbon is wrapped around her upper body, just below her breasts, with no visible knot. She does not wear shoes.

She seems to prefer strong, handsome men with strong conviction as she is enamored with Tsukasa and is heartbroken when he is cryogenically frozen in order to save him. Despite this, she has great confidence in her abilities as a former reporter to determine who will be the best to revive, whether working for the Tsukasa Empire or for the Kingdom of Science.
It seems she is particular with the kind of man she likes and doesn't just focus on looks or strength, as Ryusui 's proclamations of her as being beautiful did not move her at all (she even seemed confused but not disgusted) [10] though she did get embarrassed and blush heavily when he was first revived and fully naked. She also reacted with comical disgust and exasperation at Moz 's antics, particularly due to his desire to protect the "cute girls". [11]
She was initially a firm believer in Tsukasa's philosophy of not reviving greedy or rich people, fearing they would plunge the new era in chaos. This was best seen when she did not want to revive Ryusui, though admitted her views of him changed after she got to know him. [12] From this, it is seen that she can alter her perspective of a person after getting to know them as an individual.
She is so passionate about being a reporter and photography that she agrees to exchange her last bit of revival fluid in exchange for the tool of her trade, a camera. Once she gains the equipment, Minami wastes no time in reporting Perseus ' voyage for America.
On a side note, she seems to love clothing, becoming quite happy when the Kingdom of Science manages to create cloth and being one of the first to purchase a set of clothes for herself. Though oddly enough, she continues to wear the same primitive outfit despite having new attire, not even bothering to wear shoes.
She seems to be emotional, developing a strong attachment to Tsukasa and crying when he is cryogenically frozen for a long time before Senku snaps her out of it with a job. Similarly, she cries when Senku gives her a camera and when a good portion of the Kingdom of Science goes on their voyage, she wants to take a picture to commemorate it, crying because she understands that it may be a long time before everyone meets each other again. She is in tears of joy at Tsukasa's revival and nervously states how happy she is to see him okay.
Minami likes to pry into people's relationships, as she questions Kirisame and Kinro on their status, leaving them flustered. She was excited at the thought of Ruri and Chrome 's obvious attraction.


Dr. Stone

Mirai is a young girl with a blonde bob and short bangs. She has a round face and large brown eyes, with thin dark eyebrows. Her skin is pale. Her petrification scar is a jagged line in the shape of a halo around the crown of her head.
Her primary outfit is similar to Yuzuriha 's, having been designed to be put on her before she was depetrified, and was also made by Yuzuriha. [9] It consists of a sleeveless orange dress with navy blue ribboning down the sides, ending mid-thigh. The dress has a fur collar similar to Tsukasa's lion pelt, but is much smaller and tied at the front with the same blue ribbon as her dress. Her shoes are sack-like, tied at the ankle with darker brown soles similar to the ones worn by the others of the Tsukasa Empire .

She is loyal to her brother, and after hearing the story of how he tended to her, she sought to repay it by staying by his side. [10] As she is still a child, she has a natural curiosity and gets excited by new things. This was seen when she took part in the Kingdom of Science 's way of life with inventions.


Dr. Stone

Moz is a tall, muscular young man wearing pauldrons that appear to be made of stone. His stone guards were destroyed during his fight with Hyoga. He is shown to have replaced them while in America.
When posing as an invader, he wore a a black cloak and different outfit. [10] In the final chapter, he wore a modern time suit at Taiju and Yuzuriha's wedding and was apparently regarded as handsome, due to being seen getting attention from modern time women.
He has dark dreadlocks that are tied into a low ponytail. He has facial markings of unknown origin that extend from the top of his eyebrows in a curl, to between his eyes, similar to Kirisame's.

Moz is a cocky, adventurous and easygoing man who enjoys the company of beautiful women, and strong people. He giddily looks forward to the harem selection every year, hoping for cute women to appear. He becomes fascinated with Kohaku upon meeting her, due to her combination of strength and beauty, two things he appreciates greatly.
He enjoys this fun to a fault, allowing Kohaku into the harem despite her nearly breaking Minister Ibara's hand. Even in the past, he lamented having to petrify the young escaping Amaryllis , recognizing how beautiful she could potentially be in the future. He also showed attraction to Luna , immediately commenting on her beauty.
Despite all this, he possesses a sharp instinct and is cunning, and it is hinted that he knows a lot more than he lets on. Another glimpse of this is when he reminded the enemy that they were shorthanded and it would be best for them to not kill him and his friends because they were needed. This caused the Perseus crew to note that while he is cruel, he is strangely intellectual about such a topic. Minami correctly describes him as "selfish, strong as an ox, and calculating to boot" with Kirisame adding on that he is "the last person you'd want to make as an enemy, but a surprisingly reliable ally". [11]
In battle, he lives for the thrill, as seen when he fought against Hyoga who he found to be a worthy adversary. Even after being defeated, he showed himself to be a good sport and even asked his victorious opponent to give him lessons. [12] He will also show respect to fellow warriors, as seen when he complimented Matsukaze for holding off the grenades.


Dr. Stone

Namari has short hair with a smooth top and angled sides, with bangs that cover her right eye. She has large, tired eyes that don't shine at all and thin eyebrows. Her mouth is usually in the shape of a three with a single yaeba tooth sticking out. She appears slightly chubby when first drawn in the manga but seems to lose weight almost immediately.
As a young girl, Namari is still relatively short compared to most of the characters. She wears a dark, verdant green dress tied around the waist with pots of ink attached around it. Namari wears the village rope around her neck.

Namari is shown to be cooperative whenever someone asks her to draw something, mostly because she is often forced to. She also rarely speaks.


Dr. Stone

Natri is a very short old man, balding but with several inches of hair surrounding the crown of his head. The hair sticks out wildly. He has a fairly long moustache that is trimmed above his mouth and reaches his chin. His eyebrows are small and arched, high on his forehead and thicker at the ends. His eyes droop with age and have very prominent crow's feet. Natri also has wrinkles on his forehead and around his mouth. His head is quite round, slightly wider near the bottom due to his jowls. His expression is generally happy.
His tunic is a grass-green colour, with sleeves ending above his elbow. He wears the village rope around his waist, wrapped around twice and tied in the front.

Natri is the traditional wise old man, giving his opinion on things [2] and commenting on the weather. [3] When Senku first arrives near the village, he says it's fine as long as he doesn't attempt attacking or entering the village, and that no one should provoke him into doing so. He's surprisingly relaxed about the strange new person so it's possible Natri believes he's lived through enough events to not be phased by anything anymore.
He is also hard to trick and practical, as before the rest of the village head out with the car to fight the Tsukasa Empire Natri tells Senku he knows it was to help the older people make the journey. He seems to be the main link between the elderly and Senku, as Alumi nods to him before he tells Senku their plan to stay behind. [4]


Dr. Stone

Nikki is a tall young woman with an athletic yet curvy figure. She has blonde hair that is braided into two ponytails which come down to her shoulders and are tied at the ends with a blue bow. She has round, expressive eyes with large lips and an average sized nose. Her attire consists of a crude green dress with a U neckline that shows her impressive cleavage, that splits at her hips, with a sash belt wrapped around her waist that holds two bat-like clubs, and cloth shoes.
After she is depetrified again in the Petrification Kingdom , her outfit remains as a crude green dress with split hip ends, but now it has a corset design on the stomach region, with the top being replaced by a V-neckline bikini with a fur neck, and on her hips fur tussles held on by two metal plates, and on the back is a leather belt-like holster for her bat clubs.
Like most modern timers, she has a petrification scar on her body but it is unknown where. She later recreates her unknown scar as a sign of loyalty to Senku . [12]

Nikki is fiercely devoted to Lillian Weinberg . It is implied that in the modern world, she was having a rough time at school and listening to Lillian's songs saved her. When she listens to Senku's broadcast, she is able to tell through Gen 's disguise of Lillian due to having a wide knowledge of trivia facts about her. However, once Senku states he has the final surviving copy of Lillian's song, she quickly changes side from Tsukasa's army to Senku's Kingdom of Science to help protect it.
Like Kohaku, she is quite strong for a woman and is shown to handle a great deal of the physical work alongside Kohaku , Magma, Taiju , and Yo. While seemingly proud of her strength, she gets annoyed when others point out her lack of femininity, at one point kneeing Magma severely (and comically) in the crotch for stating she didn't count as a beauty (though, she did agree with him). In addition, despite her strength, she is actually extremely feminine. While making cloth for the hot air balloon, she suggested dyeing it in many different colors. In addition, when writing captions on photographs, her handwriting was so girly and cute people mistook it for Mirai 's at first (before she corrected them). She also demonstrated desire for more girly clothing once Yuzuriha began mass producing fashionable modern clothing.
Gen has also pointed out that she is perhaps the purest maiden there is, since when she was asked to fake being in love with Hyoga to try and convince him to fight alongside them, she got flustered at the idea.


Dr. Stone

Oarashi is a very muscular man with a large build. He has a solid, square jawline and a large mouth with a deep labiomental fold. He occasionally has dimples when he smiles wide. His eyes are deep-set and shaded in black all the way up to his eyebrow. He has small, dark pupils with no shine. The tail end of his eyebrows have a large swirl curling up and inward, similar to the swirl designs on the other Petrification Kingdom warriors. He has a wide, flat nose, that is slightly upturned with a low bridge. He also seems to have no hair anywhere on his body.
He wears a pair of simple pants, wrapped tight around his ankles and held up by a rope belt adorned with the symbol of Treasure Island . The symbol is an upright isosceles triangle with a divot taken out of the bottom and a starburst shape set behind it. Beneath the symbol, there is a large curling loincloth that reaches to his knees. Oarashi forgoes a shirt. He also wears a headdress shaped like a jackal’s head that covers his upper shoulders, scalp and nose.

Oarashi is boisterous and proud of his strength. He has a tendency to include the word miracle or some variation of it whenever he speaks, especially when describing his own power. [8] He isn't the smartest person and knows it, but since it's the only thing preventing him being the best warrior, he takes pride in that fact. He has a tendency of forgetting or mistaking uncommon words, such as forgetting the word "fate" and guessing "fat" until someone corrects him. [9] His verbal quirk seems to be huffing at beginning of his statement ("Hrrrmph" in English, "クウ〜" kuuu in Japanese).
In his opinion, muscles make the man and wants to find a girlfriend who understands that. As such, he was easily seduced and distracted by Amaryllis touching and complimenting his biceps. [10]
Because he isn't the smartest, if he can't solve a problem with brute force, he can become scared as he was horrified and worried about Ibara 's plans.
