Kenichi: The Mightiest Disciple

Jennifer is a young woman with long blond hair down to her waist and a green headband up top. She usually wears white gloves and a light blue dress having a long side on her left leg and the other completely exposes with a blue band on the thigh usually holding her gun and high heels.
During the Eternal Sunset, she still wears her usual headband, but with a new military outfit. She is now seen wearing a revealing short top with a short bulletproof vest worn over it, with armored shoulder plates, black gloves, combat boots, stockings that go just pass her knees, and ripped thigh-high jean shorts that are unbuttoned at the top. She has a string of Hand Grenades strapped to her chest, and a small travel sac filled with various ammunition and a military-grade rifle, both of which see carries on her back, a bandoleer belt filled with ammo strapped around her waist, and holsters for her guns.

For her age, Jennifer is a strict and serious young woman. She can also be intimidating, such as demanding Kenichi and his friends to stay out of the way during her investigations and pointing her gun at them. However, she does have a childish side, such as demanding (while sobbing) from Sakaki over why Shigure was with him and rolling around while doing so.
Jennifer is in love with Shio Sakaki, claiming that she is his fiancé, when in fact he claimed that his "love" for her was because he was drunk and didn't know any better. She also becomes jealous when she saw Shigure with Sakaki, threatening him with a gun for "infidelity". Nonetheless, she respects him enough to let him choose what he wishes to do, as she chose to let him leave after the tournament ended, seemingly moving on from her love for him. Like her father, she is affiliated with the Katsujinken and uses the code word "angel" to voice the action of her plans. Unlike her father, Jennifer isn't above using her guns to kill somebody, as seen when she angrily shoots the fake Fortuna.
Since her father's death, Jennifer had a strong desire to avenge him by killing his killer, Fortuna. She was willing to even put aside her Katsujinken ways just for vengeance, something Sakaki tried to reason with her, but her hatred blinded her. However, after seeing Fortuna defeated by the Shinpaku Alliance, all of which were still injured from there fights before (except Hermit), rather than take her revenge, Jennifer laughed out uncontrollably over him being beaten by children (an irony due to her being the same as them) and finally lets go of her hatred and desire for revenge and instead chooses to let him be arrested, thanking Sakaki for teaching her a lesson.

Kenichi: The Mightiest Disciple

Ono is a young girl of average height with short dark brown hair, she wore glasses, and is usually seen in a casual teaching outfit or a jogging suit while on the camping trip or heavy clothes on the ski trip.

Ono has a rather carefree, kind and softhearted personality for a teacher, commented on many times by principal Yasunaga. This even comes to the point where she relies on Boris Ivanov to uphold order as her class monitor when the Yomi member "transfers" to the school.
Out of all of the YOMI transfer students, she held a deep respect for Boris, particularly due to Boris doing anything she asked without hesitation and always did good deeds at the school that left a great impression on her, stating she would miss him a lot for his actions. When Boris had to go home, it left Ono crying tears of sadness (for him leaving) but also of joy (for his last good act as a student at the school). She was also oblivious of his fight with Kenichi, believing they were just having fun as friends.


Kenichi: The Mightiest Disciple

Kōgyoku is a young woman of average height and fairly well built. Her hair is pulled back with strands striking out in the back and bangs in the front. She wears a dark colored shirt and light-colored pants.

Kōgyoku Dō is not easily impressible. She is very stubborn, aggressive and cocky.


Kenichi: The Mightiest Disciple

Mikumo is rather tall and fair-skinned. Deceptively youthful looking for her advanced age, she appears as a beautiful woman in her late 20's to early 30's. She is slender in frame yet exceptionally voluptuous with long shapely legs, wide hips, round rear, slim waistline, and a considerably well-endowed bosom. She has brown eyes and flowing black hair that reaches her lower back and bangs that hang over her face. Commonly, she is seen wearing a shrine maiden outfit which was consisting of a red hakama and white kimono with white tabi while wearing straw sandals. Her kimono has red lining and eye-like designs at the end of the sleeves, which are loosely banded with red strings to the rest of the kimono. She generally wears rather her kimono rather open, revealing her ample cleavage. She also wears red armguards with red lining and a red "x" on the backhands. Around her neck, she wears large wooden prayer-like beads.
In her youth, her hair was shorter, down to her chin and she was slightly shorter with a comparatively smaller bosom.

Mikumo is one of the most emotionless and serious members of Yami shown. She rarely shows any emotions other than surprise and always keeps a melancholic face. She believes keeping emotions in control is important for battle and that losing one's temper will dull one's skills. With Chikage, whom Mikumo treats very well, more so than any other member of Yomi (aside from Sho), possibly because she's her disciple and seems to treat her as her own daughter. However, her relationship with Chikage at times is not as maternal as it would appear, as Mikumo is more focused on turning Chikage into a ruthless killing machine rather than as a person. After she personally witnessed Chikage crying over having hurt Ukita and Kisara, Mikumo knocked her out and attempted to brainwash her into becoming a ruthless killer because she wanted to "break" her. She was also very angry when Chikage abandoned their plan to help the pride of their masters rather than kill the Shinpaku Alliance, even going as far as to leave fighting the Ryozanpaku masters just to stop her. She seems to be fond of meditating, as she tends to meditate when she has free time.
Her lifestyle seems at times to be a contradiction. While normally appearing to have strong traditional Japanese values, with how she dresses and decorates her room, she is also rather flashy choice in means of transportation, as she has been seen driving in a sports car.
In battle, she is very ruthless, showing little to no mercy even to a fellow Yami member such as Diego Carlo and even attempted to kill him and his disciple Rachel Stanley when they both were defeated and could not fight anymore. However, she does have some honor, agreeing to a 1-on-1 fight with either Sakaki or Shigure. She has a habit of referring to others, regardless how old they are, as brats.
Mikumo also has little to no sense of comradeship, as when Sai Kagero joined the side of Ryozanpaku, she had no qualms in viewing him as a traitor and brutally murdering him just to prove a point.
Despite being one of the most powerful masters in the series, she has no problem using petty tactics such as threatening the Ryozanpaku masters with giving orders to Yami control room to have Shigure executed should they interfere with the plans. This act of hers deeply enraged Cyril Rahman to the point that he launched a devastating attack at Kushinada while criticizing her with the fact that she is willing to use such a dishonorable and cheap tactics to win the war. It should be noted that her behavior drove Cyril Rahman to switch sides and become an ally of Ryozanpaku.
Mikumo holds the belief that empathy is weakness and that the strong do not let their heart be shaken by the weak. She used this to her advantage to make Ethan Stanley fight more ruthlessly against Kenichi to save his sister. However, she acts oddly feminine when she recounts her past adventures with Hayato, chiding him for being "hardly charming", covering half of her face with the sleeve of her hakama, and referring back to the events as "the hot fires blazing between us".
Upon witnessing Agaard, Sougetsu and Cyril ally with Ryozanpaku, Mikumo finally lost her calm emotionless demeanor and reacted in frothing rage. She then chooses to willingly move ahead with the plan solely because they were provoking her.


Kenichi: The Mightiest Disciple

She wears an outfit similar to her master and also looks like her master with light colored hair and is full figured with big breast's and rounded hips. Her eyes look like they have crosshairs in them.

Like the rest of Yomi's Armed Division that have a hated of the Unarmed.


Kenichi: The Mightiest Disciple

Rachel is a young fairly tall girl with long wavy blond hair down to her back and a very curvaceous figure and well-endowed breasts, both being more than most girls her age. As a civilian, she usually wears her school uniform (that she modifies to be more revealing to show off her figure).
When she fights, Rachel wears her wrestling outfit for fighting that has arm bands with tassels on it with a revealing V-neck cover showing her breasts and has a very short skirt with tassels that reveals most of her legs and thighs. When she wants others to look at her, she tends to wear revealing outfits for attention.

Rachel has a very flamboyant personality, always wanting to be the center of attention, which she often achieves. She easily becomes upset whenever others gain more attention than her and she claims they're "taking the spotlight" and is willing to perform anything to regain the attention of others, even if it means she embarrasses herself by ripping her clothes to do so, showing she's an attention seeker. Ethan said that as long as she has attention, she does not care what happens to the world. She's selfish, spoiled, hot-tempered, and sarcastic. She's also a huge flirt, having Kenichi (unintentionally) grope her breast and teasing Kenichi about it despite it being an obvious accident and even kissed him on the cheek to make Miu very angry and even jealous.
She is also a very aggressive person and the more dominant of Team Gemini, often seen yelling, punching, and kicking her brother, and he, in turn seems very meek in front of her presence, despite their great difference in size. Despite this, Ethan loves his sister very much, but Rachel rarely shows any form of care towards her little brother.
Rachel seems to enjoy battle due to the attention it gets her, but is easily riled when an opponent grabs her attention, forcing her to beat the opponent in a very aggressive way. However, she usually holds back so as to create a more "spectacular" show in a somewhat sadistic manner and enjoys the suffering of others. She also follows her master's rule to fight only when there is an audience. Rachel also seems to have a penchant for humiliating other female fighters during a fight, as seen with the fight against Renka, where she subjected the girl to perverse submissions and in their second fight tried to take off Renka's swimsuit to embarrass her but showed disappointment that no one would see, showing clear signs of sadism and malice and even smiled at her cruelty towards Renka.
She displays the ability to manipulate and control the emotions of the crowd several times, an ability often exercised as she is always eager to be the centre of attention. Frequently used in this is the element of surprise, where she pretends to be beaten and launches attacks back at her opponent, thus getting the most attention she can.
However, Rachel has shown some (if any) level of compassion towards others, such as when Miu was kidnapped by Jenazad, she took pity on Kenichi and decided to help him, and his friends locate her due to the Shinpaku Alliance saving her from him before. Also, her time with Kenichi and his friends seems to have helped her mellow out somewhat, as when Kenichi claimed she was a friend for helping him and the others save Miu from Jenazad, Rachel was shocked and even unable to understand the situation, thereby implying she's never really had a real friend, nor does she understand the prospect of friendship.


Kenichi: The Mightiest Disciple

Lona is a young woman of average height with long wavy black hair in a ponytail with dreadlocks that frame her face down to her shoulder's violet eyes and dark tan skin and a fairly endowed figure. She wears a revealing Tidat outfit that exposes her backside and some of her lower back along with some of her legs, sleeve guards, knives on her hips, a cape over her shoulders and goes barefoot. Like her brother, she wears some jewelry, such as earrings and a decorative headband.

Despite her status as princess of her kingdom, unlike her brother, Lona is a very modest, honest, respectful, and kind woman who does not demand any specific respect from others, such as telling Batuan that it's alright if Sakaki and Kenichi do not bow in her presence. She cares very much for her kingdom and her subordinates, such as Sham whom she treats like a little sister. Though she's calmed most of the time, she has shown herself to be relatively laid-back with a sense of humor. Lona doesn't seem to have problems bathing naked in a forest or even if males see her, such as keeping her cool when Kenichi accidentally saw her naked and didn't act surprised and knew he looked accidentally only wanting to speak with her.
As a princess of her country, she deeply loves her country, going as far as to help take down Silkwat Jenazad due to his corruption and help avenge her brother, showing that deep down, she loves her brother very much despite what he's done in the past. Despite being royalty, she is not above bowing before those beneath her, such as gaining Kenichi's and Sakaki's trust by bowing before them and swearing loyalty to the two.
With her family, she loves them just as much. She loves her brother Jihan very much, such as holding no hatred towards Kenichi for defeating him and knows he tried to save his life from the snowstorm and is aware of Jenazad killing him. She even wished to avenge him for his sake and was very happy and relieved to see him alive and how he saved her life. Despite her hatred towards Jenazad, even she bowed to mourn his passing.
It's shown that Lona has developed an immense crush on Akira Hongō despite the age difference. As she becomes impressed by his abilities in fight and even blushed in amazement by how well he's fighting against Jenazad. She was also horrified and was deeply devastated by his presumed death at the hands of Jenazad and was greatly relieved that he survived and worried over his condition after he won.


Kenichi: The Mightiest Disciple

Raichi is a young short girl with long bright pink hair down to her waist that she has tied up in two pigtails and green eyes. She wears a tight red battle outfit with a helmet, shoulder pads, elbow pads, a groin pad, and kneepads. She also wears gloves, goggles, and boots giving her a type of skater appearance. For casual wear to look more normal, she's has been seen in a light-yellow top and a green miniskirt and sandals.

When she first met Kenichi, she showed to be a kind and cheerful person and a bit playful. Like Kenichi, Raichi loves flowers and was interested on how Kenichi knew so much about it. In battle, Raichi was originally very aggressive and brutal in combat, showing no mercy to Kisara or the other member of Shinpaku Alliance. She was also quiet, rarely speaking unless she chose to. She can also be taunting, making fun of Kisara for having small breasts by groping her own. She is also insulted that Kenichi wouldn't hurt her due to her being a girl, stating it shouldn't matter in a fight. However, unlike her father, she doesn't desire to kill others and only wants to end things peacefully and only knock out her enemies. When Kenichi tried to end things peacefully due to him seeing how kind she is deep down from their time from before, Raichi, moved by his compassion, sheds tears of sadness over her situation of having to kill him and choose to give up revealing that deep down she doesn't want to kill others and is forced to thanks to YOMI. After her fight with Kenichi, Raichi has become much nicer and friendly and more helpful such as helping Kenichi and Miu take out the bomb on the ship where Diego was fighting. Also, she seems to have developed a crush on Kenichi, such as blushing around him and grabbing his arm after the fight, causing Miu to get jealous. She also reveals her flirtatious side, teasing Miu that if she doesn't make a move on him, she will.


Kenichi: The Mightiest Disciple

She is seen wearing a biker suit with long hair going down to her waist. She appears to be very beautiful, so much so that Akira Hongō and Hajime Suzuki were shocked upon seeing her. A noticeable physical trait is her slender yet surprisingly developed and curvaceous-frame, especially her well-endowed breasts. She also sports a lean yet well-defined build.

Shio's older sister seems calm even when seeing a gun. She is also described by her brother as "someone who isn't needed to be looked after". By her brother's description she has a rather wild character and he appears to be slightly scared of her.


Kenichi: The Mightiest Disciple

Sham is a young girl with short brown hair sticking up on her left side with hazel eyes and has dark skin. She is normally seen wearing a green bikini-like outfit with yellow trim with strings and several bracelets on her wrists and ankles as well as sashes connecting from her wrist bracelets to the hip strings of her bikini bottom along with a gold charm on her forehead. When spying or traveling, Sham wears a cape over her back, and she has a knife on her side for combat or for self-defense. One time she was also shown carrying a purse.

Sham is rather calm and levelheaded for someone so young. She was very loyal to Jihan and even mourned his presumed death. She even shed tears of joy seeing Jihan alive again and ran up to him to hug him to which he returned, showing Jihan cares very much for Sham. With Lona, she's just as loyal, as Lona seems to treat her as a little sister rather than a servant. She does not like others who insult them and will defend them. She was also briefly scared of Sakaki , but eventually considers him and Kenichi friends.
Despite her maturity, being a child, she's still immature for her age. This was shown when she got easily scared and intimidated when Sakaki snapped at her for chastising him for being rude to Lona. During the final battle she was upset at Hartini trying to interrupt Sakaki when he was talking and how Hartini was smarter than her and showed jealously. She also appears to be absent minded such as how she fainted under Jenazad's killing intent and thought she passed out from working too much.


Kenichi: The Mightiest Disciple

Yui is a young woman with long hair that reaches to her lower back with bangs styled in a straight Hime cut.
She wears what appears to be a well dressed School uniform.

Yui's personality is unknown, but she seems to be calm and mature.


Kenichi: The Mightiest Disciple

Alan regularly wears a white suit with a rose in either his jacket pocket or his mouth. He has lanky black hair, muscular build and tan skin. He scarred his face in admiration of Sakaki.

Alan Subishi admires Sakaki to such an extent that he scarred his face to imitate the karate master. This hero worship carries on to dojo practices, where he simply loves the feeling of being a master, allowing his disciples to use various unscrupulous ways of fighting, proclaiming that "strength is everything" and even defending them as his dojo's practices and techniques. Further noting this characteristic of hero worship is his lie, stating that he was the "Lost Hero of Ryozanpaku ."
Upon realizing who Sakaki was after being beaten in his group attack on Kenichi , Alan asks Sakaki to sign his notebook and undergoes a change of heart in adopting new instruction from Sakaki, now proclaiming "strength and love" and setting new principles. This new code of honor evidently becomes ingrained thoroughly, as after being beaten in a second dojo attack by Yomi 's Tirawit Kōkin , he defends Mizunuma from Tirawit's attack and falls into a coma.


Kenichi: The Mightiest Disciple

The Bantou Master is a very tall and large man. He has a muscular physique. He has long braided hair tied up in the back and a tight fighting outfit and suit. He wears a necklass of chained teeth around his neck. After his loss against Danki, he has bandages over his right eye and scars on his cheeks and has gloves with rings on them.

The Bantou Master is a cruel and serious man. He does not care who he fights nor who he kills and will cut down anyone who stands in his way, even children such as Kenichi or the elderly such as Danki Kugatachi . He is very foul-mouthed and disrespectful, losing his temper when he gets mad or things don't go his way. While he is loyal to Yami , he is not above disrespecting them should he feel like it, such as mocking Agaard for not being able to fight anymore after his defeat with Apachai or smashing his computer when Agaard mocked him. He has developed a strong dislike with Kenichi due to him having defeated his disciple Andaka with ease and suffering a loss at the hands of Danki and even tried to kill Kenichi just because his luck has turned bad because of Kenichi. He thinks the quickest way is the best way to raise a disciple .


Kenichi: The Mightiest Disciple

Danki is a short man with a bald top with hair on the sides and many wrinkles. He has bushy eyebrows and a short beard. He wears a kimono for casual wear and is missing a few molars due to being over 90.

When he first appears he is shown as apparently senile, it was later found out that he was only acting. He is usually rather oblivious and thoughtless, even in serious situations. However, he can be serious when he needs to, such as helping defend Kenichi from getting killed by the Bantou Master . After fighting, he reverts back to his senile demenor. He is fond of teaching such as growing fond of Thor and the Valkyries and his granddaughter Freya . He has shown slight pervertism, such as when the Valkyries wait on him hand-and-foot for training him and do almost whatever he wants, which he enjoys greatly. Danki seems to not like Ryozanpaku, or at least, its arrogance such as he reacted angrily to Freya's comment on how he should show gratitude for saving them. Thought, his granddaughter stated that is because of his strong sense of rivalry. However, he's grown fond of their desciple Kenichi and helped save him from Yami. He originaly sought to leave the martial arts world instead of getting into continous battles but decided to start up again after seeing Kenichi's straight forward eyes. Even tho he is willing to work of the Masters of Ryouzanpaku to stop Yami .


Kenichi: The Mightiest Disciple

Fortuna is a large and muscular bulky man with a tight suit and dark sunglasses on his face. He has slick hair on his head and a long beard to his neck.

Fortuna has an obsession with children and preys on them constantly should they gain his interest. Any child he sees with potential he immediately wishes to take and make his children, forcing them by their will or not and demands they call him "father". He desires to gain several children for himself and, should they disapoint them or of no further use of them, he will kill them at any point, showing how little he thinks of them. He's very ruthless, showing no mercy to the Shinpaku Alliance and swore he'd kill them all in retaliation. He doesn't seem very honorable for a martial artist, having chosen to blow up the tournament just for fun while Kenichi and Sho were still fighting and purposely had his men attempt to kill the other fighters there.


Kenichi: The Mightiest Disciple

Pengulu is a tall and large muscular man with a Tidat outfit and pants with boots and a bag on his hips. He has several swords on his back. He wears a skull like mask with a hat with horns on the side that are flat and his eyes appear to be very heartless.

Because of Junazard's brainwashing on him, just like he has done to Miu (before she regained her senses), Pengulu is a mindless killing machine and has completely lost his mind, only fighting without any thought of himself. In battle, he is ruthless, showing no mercy to am already worn out Kenichi and will kill anyone, be it children or his own people. However, he does obey Junazard's orders of fighting Miu to teach her a lesson, though Pengulu is still aimed to kill her. He is willing to kill 6 of Silcardo's own men.


Kenichi: The Mightiest Disciple

Sigmaringen appears as a tall fair-skinned teen wearing a dark outfit similar to his master, a long black coat. However, he has straps wrapped around his dark pants. His hair is stylized in a mohawk with the sides being shaven off and the top of his hair brushed down over his forehead. He has dark lips, small eyebrows and round irises.

From what has been presented, Sigmaringen is a brash young man who has a strong belief that weapons are superior than fists, targeting Lugh with a slice of a wooden post he cut off. He apparently has "size issues" as any comment referring to the size of his scythe and himself infuriates him.


Kenichi: The Mightiest Disciple

His hair is tied back in a high ponytail, and he is missing one of his eyes.

He thinks that he can take on all of the Ryozanpaku masters at once, showing that he holds a high degree of arrogance.


Kenichi: The Mightiest Disciple

The Spear of the West is a fully armored black knight. Underneath he is a really good looking man and probably blonde.

The Spear of the West is very honorable and shows some form of being a gentlemen. For example, he gave Shigure her clothes back after piercing the clothes off earlier in the fight and later he is seen giving her a ride on his horse.


Kenichi: The Mightiest Disciple

Gonzui is a tall and very muscular middle-aged man with a typical karate outfit on. He has an odd style of wearing make-up on his face which displays white and red markings all over, he also has parts of his hair sticking up in little wing styles, both of these features is why Kenichi calls him "Crab Head".

Gonzui is rather over-the-top and boisterous, making him like a typical Kabuki poser that performs rather odd hand stances. He is also short-tempered and aggressive, willing to challenge Sakaki despite his reputation. He has a high degree of arrogance, claiming he can defeat Sakaki easily. However, this was his downfall and Sakaki defeated him effortlessly. He also thought Kenichi wasn't that strong and thought he would be defeated with little effort, showing he tends to look down on his enemies. Although this assumption was right by his behalf, it led to him relieving Kenichi's weakness of striking his opponent and allowing him to land a solid hit upon Gonzui.


Kenichi: The Mightiest Disciple

Haruo has a rather "alienated" appearance. Slightly tall for his age, he has a slim yet solid physique, sharp fingernails and gangly limbs. His facial features are somewhat demonic: a long tongue with sharp nose, long pointed ears, and teeth that switch between jagged, fanged, or even just normal. Not surprisingly, Kenichi and many other characters refers to him as a "Demon-faced space alien" or something similar. He originally sported a puddle-bowl hair cut but later allowed the back to grow sideways. At times, when he is in a state of fierce concentration, two-pointed antenna will pop from the top of his head. Almost always, he wears his school suit as his "Battle" outfit. He usually wears a cloak while in the base of Shinpaku Alliance to claim his leadership and his Demon King" image. During D of D Tournament, the cloak he wore was a new flag which had a painted label and kanji of Shinpaku Alliance. When it comes to some ceremony or event, such as party held by himself and captains of Shinpaku or the assault of Berserker, he has worn slightly nicer clothing than his usual school uniform.

Though Niijima was initially seen as an ambitious power grabber, as the series progressed, it becomes apparent that he is actually more perceptive and empathic than he lets on and is an altruist at heart, with an almost paternal air of leadership towards his subordinates.
His proclaimed dream of one day ruling the world remains, but it is very clear that he prioritizes the well-being of the organization that he set up and everyone who is a part of it, even if it meant withholding from them crucial information and often resigning himself to peril for their sake. He is very adept at running away from dangerous situations, always leaving the fighting to the others, a trait which Kenichi adopted to "face" women in battle. Despite his often-cowardly tactics, he shows himself to be a very cunning individual, thinking many steps ahead and planning for contingencies to the point that both the enemies and allies have complimented on his leadership skills.
He is a very crafty person who watches over Kenichi's progress with a great deal of interest (and keeps his information up to date by bribing Miu with Anmitsu, her favorite food) and even treats Kenichi as his follower. He is very adept at running away from dangerous situations and can even outpace the likes of Kenichi, who can move considerably fast thanks to Ryozanpaku's training, though it only works while he is running away from somebody or something.
Throughout the series, Niijima has proven to be a very skilled escape artist, having shown to be a capable swimmer (he used this method to survive a direct confrontation from Hermit), and a talented dodger (he frequently evades fighters whose fighting skills rank fairly high, and his greatest achievement yet in this regard was seen when he dodged, along with Kenichi, a direct sword strike from a master-class member of Yami's armed division while on top of a speeding truck that cleaved the rear of the vehicle in half. A fact made apparent where he repeatedly thwarted Berserker's (one of Ragnarök's top three) attempts to ensnare him by deliberately stripping his clothes piece-by-piece every time Berserker thought he caught him, and during the D of D Tournament where, after volunteering to be part of the contending players representing the Alliance (since Freya, Thor and Takeda were crippled by Shou, leaving them only with Kisara and Ukita), Niijima more than played his part where he held the captain of the opposing team (long enough for Kisara to beat the remaining opposing fighters) at bay by keeping the distance between them through the use of continuous dodging and running, along with the clever use of minor ambushes. It is also worth noting that after the fight, Niijima alone was the only person from the Shinpaku members who took part in the ordeal and got off practically unharmed.
Despite his often-cowardly tactics, he shows himself to be a very resourceful individual (having once saved the Ryozanpaku dojo from certain bankruptcy after devising a legitimate get-rich-quick scheme, which a desperate Miu adopted at once), thinking many steps ahead and planning for contingencies to the point that both the enemies and allies have complimented on his leadership skills. He is also a skilled tactician, capable of coordinating the combat formations and ploys that the Alliance use at both in and out battle (such as postponing the battle between Kenichi and Chikage by convincing a classmate to invite the latter into a birthday party).
Despite the fact that he, as well as most characters, calls himself evil, he usually finds ways of helping his friends when needed, though he does so in his own odd way. As the series progressed, his character is seen developing from an ambitious and conniving opportunist to an altruistic, understanding and almost paternal leader who, while seemingly will stop at nothing to achieve his goals (and often subsequently getting a comical beating from those who simply find him and his ambitions to be annoying), is actually empathic towards those under his control, and considers their well-being above all else, even if it meant withholding from them crucial information (like not telling Kenichi that another Yomi was in the same school in the form of Chikage to prevent the two from seeking a bout with each other) and risking danger himself for their sake (as seen when he repeatedly provoked Berserker to lure him away from Ukita and Takeda) and even forfeited his team from the DofD Tournament to protect them from getting killed by Sho Kano, something Shigure said is the true capabilities of a leader. For the members of the Alliance itself, they appear to have developed genuine respect towards Niijima overtime as their unquestioned leader, even Kenichi as well as the captains, since their repetitive successes (be it victory or survival-wise) in battle have mostly been influenced by Niijima in one way or another.
While generally a hands-off non-combatant who prefers to keep his distance and coordinate attacks, if forced to exert himself in battle, Niijima usually relies on hit-and-run (mostly run) and psychological tactics to unnerve his opponents and render them more vulnerable and lets the more powerful fighters of Shinpaku to deal the finishing blow. He has a (more or less) finishing move called "Shadowless leap from the charge", which he uses to escape by switching positions with a nearby enemy. He has amazing information gathering and analytical skills (to the point that he can quickly identify a master-level fighter in a very short period of time), which he uses to prepare Kenichi for the many battles that he ends getting tangled into with his opponents' profiles and skills. He has trained the non-combat members of his "alliance" fiercely in the art of gathering information. Niijima's ability to collect data is chillingly effective, and in some cases, supernatural, such as the bizarre "Niijima Scan" technique that enables him to absorb ridiculous amounts of unknowable things about a person (Physical, Personal, Mental, Emotional, Skill Level, all of it...) simply by observing them for a few seconds (He was able to tell that a member of an opposing group had a crush on his ally through eye contact alone). What's more, he can ring his thumb and index fingers around his eyes to literally create a digital HUD of his target's power level and killing intent, and even has a zooming function, allowing him to view from afar as though he's looking through a pair of binoculars. Apparently, his senses are inexplicably unnatural, having once detected incoming missiles locked on to their location, and even discerned the presence of soldiers hiding in the woods to the point where even a Yomi member, Boris Ivanov, commented on Niijima's sensory skills that he immediately ordered his subordinates to distance themselves away from the Shinpaku leader. During the Eternal Sunset Arc, after giving an analysis on Kajima Satomi, the Yomi leader found his evaluation so accurate that he deemed Niijima a very dangerous individual, leading to him attempting to take Niijima's life then and there.
Niijima also has a talent for both tinkering and programming, having once constructed a working desktop computer from spare parts and even created the official web page for the Shinpaku Alliance with considerable security (as Loki found out when he tried to hack the page). He is also skilled engineer and traps master, having constructed rudimentary traps to ambush the Capoeira team captain, while at the same time running around the arena (at high speed), and even took part at supervising the renovation of the Shinpaku Alliance hideout, not to mention the traps that were stationed at Kisara's old hideout (now the Shinpaku's official base) to safeguard the place from infiltration. He is also very adept at espionage, and can occasionally be found casing the scene (with Matsui as his second aid, of course) already before the waited event takes place; he even once stole the keys to Tanimoto's house without him even realizing it (and has apparently made duplicates, granting limitless access to Tanimoto's property indefinitely, much to the latter's chagrin) and, while in a drunken state, once single-handedly hijacked a cargo ship all on his own.
Perhaps his greatest accomplishment in this regard yet was the fact that he once spied on the masters of Ryozanpaku and actually remained undetected for a time, and by the time Shigure sensed his presence, Niijima swiftly switched places with one of Akisame's training dummies, allowing a clean escape. He can even hide his presence from people by pressing his body against a shadowy area, using his bizarre alien abilities to render himself undetectable (though exactly how this works can be anyone's guess). He seems to have access to hammer-space, since he has been known to pull out convenient items (i.e. pepper sprays, striking batons, and of course, his prized PDA) from under his clothes.
Niijima is also very perceptive, and has, on several occasions, perceived minor details that Kenichi himself overlooked. His potential tempted Fortuna enough to try to convert him into one of his children even though he only takes kids with the potential to reach master class. And as stated by Kenichi himself, Niijima has a natural talent at manipulating people (either through persuasive language, or even blackmail, etc.), which would explain how he was able to form a prominent group of diverse martial artists like the Shinpaku Alliance. He also has a problem entering churches and other sacred places, as seen when he tries to enter the church where Loki had Kenichi's little sister captive and becomes weakened to the point where he must be carried. As he was being, carried his shadow could be seen struggling and screaming, and his body smoking. He's also somewhat cowardly in situations where he has to defend for himself, as he typically has to rely on other Alliance members to protect them. Niijima seem to feel kinship with those who can read/predict other people thoughts as he called Tirawit Kōkin a fellow mind reader.


Kenichi: The Mightiest Disciple

Ukita is a tall young man with a fairly lean and muscular build with short spike brown hair that sticks up and has the lower half shorter and has a scar under his chin. He typically wears his Judo outfit for fighting and his school uniform and has sunglasses at all times. Also to note is that underneath his thug-like appearance, especially the scar and the sunglasses, he has kind eyes and was said by Takeda to have been one of the five most handsome men in Ragnarök. Recently, Shigure has given him Steel Arm Guards, along with the rest of the Shinpaku Alliance.

Ukita was originally just a thug that enjoyed fighting and winning by using underhanded methods. He has a passion for Judo and that caused him to practice it and eventually join Ragnarök. Since his and Takeda's defeat at the hands of Shirahama Kenichi, Ukita has become much nicer and more honorable, going as far as to no longer act like a delinquent and fight to protect those dear to him. Since joining the Shinpaku Alliance, he's grown to be fond of the group and enjoys the time he has with them and the new friends he's made.
Ukita and Takeda are best friends and have known each other since their time in Ragnarök. They always have each others backs and are always seen together. Ukita has shown to be very loyal to Takeda, as when Takeda quit Ragnarök and Ukita was ordered to take him out, Ukita changed sides and choose to walk down the path Takeda goes down for the better. The loyalty and dedication Ukita has to Takeda as a friend is so great that Ukita was more than willing to interfere in his fight with Lugh and be the only one to try to save him without hesitation stating that even though he's a martial artist, he's Takeda's friend first, something Kenichi agrees with.
Ukita has a crush on Kisara, as shown when he tried to impress her by giving her a picture book and because he has pet cats to let her come over whenever she wants to play with them. He always tries to impress her with anything he can come up with and show how much he cares for her and will defend her from any attack without hesitation, such as when they fought against the Capoeira team members, he shielded her from the leader despite her saying he shouldn't. While Kisara denies any feelings towards him, she has shown to harbor even deeper feelings for him, such as blushing when he said he needs her help with something. She was also against the plan Niijima had that involved him getting beaten to death by the Capoeira team. She also worries over his condition in fights more than any other member despite her saying otherwise. She becomes flustered when others mention she likes him.
Ukita is also very oblivious to the obvious around him, such as Freya's crush on him and even Shiratori's. The prime example was when at the pool he walked right by Shiratori in her swim suit and only when she put on her jacket, he said he found her "doppelganger" that looked just like "him" but as a girl, resulting in Shiratori to kick him in the face and Takeda running off laughing hysterically over Ukita's blindness.
Ukita has shown to have a strong bond with Kenichi. The two are able to talk about things that Kenichi can't talk with about others. Kenichi even tells him things about him that his masters and other members don't know about, showing a strong amount of trust in him. The two can also relate about how they feel towards Kisara and Miu respectively. He even gave Kenichi advice on how to deal with Miu and was under the assumption they were very intimate with each other. He also can act like Kenichi when the two try to impress the girl they like. He later revealed to Miu that he has a strong amount of admiration of Kenichi due to how far he's come as a fighter and as a man so he's worthy of being with Miu and even thinks Kenichi helped inspire himself to become stronger. His master Machino also commented he's got fire inside his heart lately.
Due to the fact he's the weakest martial artist of the Shinpaku Alliance, Ukita has some self-doubts in himself as a fighter and even as a man. During the double date, when he tried to protect Kisara he was left unable to and Shiratori topped him in everything and Kisara said she'll protect him, somewhat hurting his pride in a similar manner to Kenichi. However, this would cause him to gain the courage to face Shiratori to win Kisara over and in an effort to prove his worth as a fighter.


Kenichi: The Mightiest Disciple

Meatman is a very large and overweighted, yet muscular man with long curly hair and wears a typical lucha libre outfit and mask. He's about twice the height of Kenichi.

Meatman is an arrogant and cocky fighter. He believes whatever his master Diego does is right. He enjoys fighting and makes it a game to have fun and, like most Luchadors, he tries to show off as much as he can. He does not care about all the lives that would die from the explosion and believes he would live thanks to his master.


Kenichi: The Mightiest Disciple

Okamoto is a tall man with short dark hair in the back with long bangs on the side that frame his face. He is usually seen in nice suits. It was revealed that he is just masking his appearance to infiltrate the Yami base.

Okamoto appears to be a relaxed man, but at the same time very interested in other's personal matters, such as the Ryozanpaku's search for Shigure. While he appears to be on the side of Ryozanpaku, however, according to Niijima there is something suspicious about him.


Kenichi: The Mightiest Disciple

He has grey fur with a white belly and has a pink ribbon attached to his tail.

as Tōchūmaru is a very mischievous mouse, as he tends to get Apachai in trouble a lot for other people's food getting eaten. Shigure notes when he finds something he likes, he doesn't want to let go of it, such as Kenichi's yin-yang badge, having used it as a surfboard and only let it go after Akisame made him a miniature bike.
He tends to serve as comedic relief throughout the series, as shown when he follows Kenichi and lets Shigure know via a signal and puts a tracker on him when Kenichi trusts him. Even when attempting to fight human fighters, while Tōchūmaru takes it seriously using nunchucks, the human fighter walks right past him not believing him to be serious. Like any mouse, he has a love for cheese, which seems to be his weakness. He also loves the food Miu makes for Kenichi, as Kenichi notes he tends to hide in his lunches and eat almost all of it.
Tōchūmaru is considered Shigure's best friend, as she greatly cares for her friend. Shigure is usually seen eating food with him for dinner before she started eating with the other masters. Their bond was shown when Tōchūmaru was hurt in a fight against sword users that made Shigure lose her normally calm nature and fight angrily against them for hurting him and was later relieved that he would be alright. Just as Shigure is to Tōchūmaru, Tōchūmaru deeply cares for Shigure's well-being, as he was against leaving her behind to fight all 7 of the Hachiō Executioner Blade members and risked his life to save her from her capture. His rescue even made Shigure become overjoyed at his arrival and dropped her normally stoic expression for a moment.
Interestingly, she's completely fine with the positions he sits on her, such as her head, hands, her bottom and even between her breasts, which usually serves as a running gag on his part.


Kenichi: The Mightiest Disciple

Thor is a very tall and large-framed man. He is lightly tanned with short black hair and with long sideburns. He sports a rotund build with a defined and well-muscled build with a large belly; what he considers the perfect mixture of muscle and fat. He typically is seen wearing a sleeveless kimono to show off his muscular arms and usually doesn't wear any footwear, but sometimes wears sandals as an option. During his days as the Seventh Fist of Ragnarök, he wore black gloves with golden marks insignias shaped like Roman numeral for "7". Recently, Shigure has given him Steel Arm Guards, along with the rest of the Shinpaku Alliance.

He fights using a combat-sumo fighting style and joined Ragnarök in order to make his dream of making the combat-sumo style mainstream. Despite being in Ragnarök, Thor has a high degree of honor, capable of reasoning with foes, and considers upholding the rules of sumo wrestling his top priority. Thor is also perceptive, even while in an imminent rage, having immediately discerned exactly who Kenichi was after their first encounter based on the information that Siegfried passed on to him. Thor believes that the Shinpaku Alliance is composed of true comrades, unlike Ragnarök, during which he believed Siegfried was the only person who was his comrade.
Thor has a strong liking for fellow Sumo Wrestlers. Such as in the D of D Tournament, he cheered for one. He also says things that most Sumo Wrestlers say.
Thor is also afraid of heights, such as when he needed to jump out of a helicopter, he grabbed the side stating he couldn't do it. However, he put his fear behind him for the sake of his friends. Like Kenichi, he is also afraid of riding dangerous rides such as rollercoasters, something Kenichi shares with him.


Kenichi: The Mightiest Disciple

Diego is a tall muscular man with long black hair he keeps slicked back. He usually wears a dark red Lucha Libre wrestling outfit and his laughing mask to show off his happy-go-lucky attitude.
When he fights seriously, he removes his smiling mask to the angry mask to look very angry and no longer smiles. Under his mask is a sunglass mask to cover his eyes (possibly because he's too embarrassed to show his eyes without his mask on).

Diego is primarily known as the Smiling Steel Fist in the Nine Fists due to his flamboyant and goofy personality. He believes that a fight must always have an audience and that the fight is for the audience's enjoyment, and that after a fight the loser must obey the winner. He has been shown to always be smiling or laughing even when angry. This personality seems to have rubbed off on his disciple. It's very rare to not see him smiling in a goofy or relaxed manner, as when he frowns is usually when he's upset by something or angry with his opponents. He also seems to care greatly for his disciple, Rachel. One of the few times he frowned was during his imprisonment in Big Lock while wondering if she missed him. He even pictured her crying while holding his mask. He also has a liking for manga, as he was seen reading one while in Big Lock and was glad his favorite one is still going on.
Despite his tendencies, Diego is also shown to be cunning, as shown when he matches up Garyu X with the Muay Thai Taifun team, which secretly had a 51-year-old master in its ranks. During the fight, he pretends not to realize the elder's true identity and enjoys toying with the information when presented with the truth. It is revealed that he lied to the elder about the tournament being for people "20 and under", when in fact the tournament was for those "under 20", possibly as a measure of insurance for invalidating the elder's future battles in the D of D. This takes on a grimmer tone when he places the targets he was sent to assassinate on a ship and fights with Kensei Ma while on the ship, caring not for the wellbeing of those people or the fact that blowing up the ship would send him into the sea as well.
Despite his cunning and goofiness, Deigo does have some honor, as he gladly accepted his defeat at the hands of Ma Kensei and willingly gave him his mask and went to Big Lock.


Kenichi: The Mightiest Disciple

Honmaki is a middle-aged man of a short plump stature with short hair and glasses on his face. He typically wears a suit for his work.

Honmaki is a peace-loving man and works together with Ryuzanpaku to help take down Yami. He is a caring and very brave man, devoting his life to protect the innocent and even willing to help fight against Yami members despite his age and refuses to run despite how he has no martial art skills. He's grown to develop a respect for the Shinpaku Alliance for their efforts for helping keep him safe and deliver the Yami information safely. He also gets along with the Masters of Ryōzanpaku ', especially the Elder and usually is seen complementing their efforts from fighting. He is very loyal to his work as a police officer, having been one for over 30 years.


Kenichi: The Mightiest Disciple

Menang is a dark-skinned man of average height with a turf on his head, Tidat clothes and short dark hair.

Menang, like all other Tidat warriors, is loyal to Jenazad. He seems to have developed a respect for Kenichi Shirahama after seeing how he was fighting Miu and Pengulu alone to bring Miu back to her senses and that he had no chance of winning. He was so amazed by his fighting spirit that he disobeyed Jenazad to throw Kenichi's guards to him to save him from Pengulu. He stated his reason for it was for Tidat's pride and for Kenichi's favor since he was fighting a battle that was not in his favor and how the boy reminded him about what martial arts was truly about, something he had forgotten long ago. His respect and honor are great enough to save Kenichi and Miu (who was unconscious) from his own men and help them escape. He is also a firm but loving father who cares for his daughter very much.


Kenichi: The Mightiest Disciple

Mototsugu is a tall middle-aged man with short dark blue hair and a fairly lean figure as he keeps himself in decent shape for a man his age.
He's typically seen in suits from work or just ordinary shirts when around the house.
As a young teenager, he was less lean and had more hair on the top of his head that was more full and smooth.

Mototsugu is gradually impressed with Kenichi's growth as a man but feels sad that his son is growing further and further away from him. He often acts in a goofy and rather foolish manner and is usually used as comedic relief of the series with his over-protective attitude when it comes to his sons' well-being, especially when he prepares to use his shotgun, Sebastian, to get his son back. He even chooses to try to bring him home by force after hearing of how cruel his training in his dojo. And when Honoka asks if Natsu could come over he tells her to do it while preparing to use his shotgun, Sebastian, on him.
He tends to be aggressive, which is natural for those who possess the Dou Ki, especially to strangers who come close to his family and those who he believes them to be hurting his family, which makes him an overprotective family-man. Mototsugu himself stated that he would sell his soul to the devil for the sake of his family. He was shown to encourage his son on his decisions sometimes as shown when he gave a speech before going to the D of D and when he stood by his son side when he wanted to go and see his old friend Ryuto and told his wife and daughter to grow up and that for men when it comes for the friendship they must go.
His wife, Saori tends to make sure he doesn't do anything too rash or embarrassing towards their children, especially Kenichi. He claims that he was quite popular with women Kenichi's age and Saori often left him love letters for him. However, in truth, it was him who gave her tons of love letters to win her affection, which actually worked. She usually has to knock him on the head to keep him from doing something drastic in comedic relief. However despite this, the two love each other very much and she's often impressed by his actions of bravery and seriousness when it comes to their son, as she always calls him "Honey".


Kenichi: The Mightiest Disciple

Tanimoto is a tall fair-skinned man with blue eyes (violet in the anime), spiky yet wavy chin-length blond hair, with a well-defined built and respectably muscular frame. A noticeable trait of Tanimoto is the change in his eyes during the situation he is in. While maintaining his kind-demeanor, his eyes are big and calm. When angered or fighting, his eyes narrow with small cat-like pupils. A recurring theme in his appearance is that he is considered quite handsome by nearly all girls near his age.
Tanimoto typically wears a white-grey shirt with a red cross on it, similar to the design of a crusader, at school. As Hermit his outfit is very similar to the outfit of his savior when he was a child, Ogata, which give the hint that he was inspired to make his outfit to look like his. Tanimoto wears a dark hood and cloak with arm bands and leather boots, with a pentagram sewn into his leather gloves. Originally, the symbols on his gloves were that of the Roman numeral number six (VI). However, after his defection from Ragnarök, he changes the symbols to a pair of pentagrams.

Tanimoto is the president of the drama club at Kenichi's school and is considered to be the school's "prince", pretending to be a kind and soft-spoken school student, which plays well seeing how he is popular with both teachers and students. To further the illusion that he is a gentle and kind person, he makes sure not to reveal his muscular build, and even claims that the sun is bad for his skin just to prevent his body from being shown off during the camping trip.
He claims to have only joined the drama club to practice deceiving others and is only nice because he perceives popularity as a way to control people. In truth, he is cold, ill-tempered, and extremely prideful. He also whacks Kenichi and Nijima or threaten them whenever they try getting too close (both figuratively and literally). Tanimoto also can't stand it when Kenichi calls him Natsu-Chan (Lil' Natsu) to which he irritably responds, "Who are you calling Natsu-Chan?".
The words left by his sister Kaede " don't lose " affected him tremendously, to the point where he will continue to fight even if he is knocked unconscious as seen in his second fight with Kenichi, and later in his death match with Chou Enshin. However, this also leads to him refusing to quit anything such as when he stubbornly refuses to stop playing Othello with Honoka until he manages to beat her which, in turn, leads to him being regularly forced to do anything she asks him to do, as he loses almost every time. His relationship to Honoka is very similar to his late sister, possibly that he sees Honoka as his little sister from before.
After losing to Kenichi, he regularly discards his kind personality to those that don't already know about his true nature. Despite refusing to accept Kenichi and the others as his friends, Tanimoto's demeanor has changed considerably since meeting Kenichi and his sister. While still maintaining his aloof attitude, he has become less hostile towards people getting close to him, particularly Honoka. Surprised at how strong Kenichi believes in the ideals of friendship and how they have helped him to come so far as a martial artist have also caused him to have doubts about the path he walks and actually comes to Kenichi and his friends' aid, though he always claims he is merely doing it for his own needs such as revenge.
Since his official joining of Yomi, Tanimoto has reached a crossroad in his life; While an unofficial ally of Kenichi, he has intentionally fought each time without killing as a Katsujinken believer, while Yomi is a firm believer of Satsujinken, meaning he is destined to eventually choose one of the two paths. However, with him fighting against the Shinpaku Alliance, it seems Tanimoto has chosen the Satsujinken, however, Siegfried notes he still is good deep down. This was proven true when Tanimoto refused to kill Siegfried despite being a YOMI member. While seemingly certain of his path of Satsujinken, he acknowledges that it is not for everyone and doesn't want people like Miu to follow it. During the Eternal Sunset, it would be revealed he joined YOMI solely to help save his master from the path of the Satsujinken over the fact since he couldn't save his sibling, he would help his master save himself.
A running gag is that whenever Kenichi calls Natsu his "best friend", he immediately becomes infuriated and angrily refutes the claim to which Kenichi either ignores or is oblivious to. However, in his fight for the position in Yomi, he briefly thinks about Kenichi, finally accepting that he is his best friend despite his refusal to admit it.


Kenichi: The Mightiest Disciple

Berserker is a tall, muscular young man. He is fair skinned with dark blonde hair spiked up and blue eyes. He is constantly seen in a white sleeveless shirt, blue jeans, white sneaker, and red jacket with its sleeves ripped off. During his days as the Second Fist of Ragnarök, he wore black gloves with golden mark insignias shaped like roman numerals for 2. He is often seen chewing bubble gum.

Berserker has a calm disposition despite all the damage being done to Ragnarök and almost never loses his head, despite his seemingly ill-named position. Berserker is almost always seen chewing bubble gum and usually doesn't speak, even when something noteworthy happens. Berserker is said to be the most fearsome fighter in all of Ragnarök, and Loki even believes that he could be a better First Fist than Odin (though Loki may have simply said it in order to plant a seed of betrayal in Berserker). However, Berserker shows no interest in becoming a leader for any gang, and is actually afraid of fighting Odin, believing that the latter is much stronger than he is. Berserker claims to fear boredom more than losing during his match against Hermit . When in his Berserker mode, he's much more sadistic and brutal, going as far as to assault Hermit with everything he has without holding back and laughing maniacally.
Since having become Ogata's disciple, Berserker's personality is virtually the same, except he seems to take more interest in things around him and has surprisingly developed a sense of moral fairness during his fights (despite his calm, battle-ready attitude and the aggressive way that he fights). The biggest example of this was in his fight with Kenichi. He stated he came to fight him to test how much stronger he had become since the last time and admitted his gladness in fighting him. He even waited for Kenichi to make his Seikuken during the beginning of their fight just so he can test out his own Seikuken.
In battle 500, it was shown that Berserker has been carrying a very small grudge against Niijima , ever since their encounter during the Ragnarok Saga, and even stated that he "still owed him one" in a very serious way, which freaked Niijima out. Also, he seems to have gotten over his fear of Odin as Berserker saved the former from falling debris before stating that he now viewed Odin as a worthy opponent that he personally wants to defeat.

Kiba

Almeda wears a Blindfold over her eyes, Hiding the Shard like eye.


Kiba

He wears a mask over his mouth until Amil Gaoul (the Key Spirit he stole from Zed ) rejects him. He has a strict personality, but acts somewhat insane after he's rejected by Amil Gaoul. He is the previous owner of the Key Spirit, Pronimo , later stolen by Sara after Hugh's defeat.

Hugh's first appearance was in episode 7, in which he's shown next to his two primary officers, Glaudio and Elmelda. He used Dumas as a spy , manipulating Dumas in believing he will become the next king of Zymot by marrying Rebecca.

At an earlier age, Hugh acted as the primary retainer under Rebecca's father, who was the king of Zymot at the time. One day, however, Hugh had attempted to kill him, which was when the king placed his half key Spirit into Rebecca's forehead. Due to this fact, Hugh continuously captured Rebecca and later convinced Rebecca's father, whom he had let live, that he would marry Rebecca and become the new king of Zymot. This is only a trick, however, in order to make Rebecca's father release the shard within her head. After Hugh receives the shard, he kills Rebecca's father and casts her away, free to do whatever she wishes. After this event, Hugh became the new King of Zymot, and lusts to obtain every key Spirit he can get his hands on; this is Hugh's true ambition.

Hugh then furthers his influence by gaining the trust of many major figures within Tusk . After Hugh's campaign in the Kalbu-fu region, he meets up with Zed and finally realizes that he has Amil Gaoul in his possession. Hugh flees after he realizes that his key Spirit Pronimo (becomes whole after fusing with the fire half) cannot stand against Amil Gaoul. After Roya was to be sacrificed at a different time by the creatures of Tusk, Hugh takes glimpse of Noa's key Spirit along with Zed's, which makes his ambition burn even stronger. Hugh later retreats and continues to elaborate on his superiority within the series.

Hugh later participated in the Neotopian Joust, disguised as a representative of Tusk. After Zed was 'defeated' by Noa and taken to a hospital to recover, Hugh crept into his room at night and stole Amil Gaoul. The next day, Hugh, still in disguise, faced off against Noa in the final match of the Joust. During the battle, Noa knocked off Hugh's helmet revealing his true identity. At this point, Hugh summoned Pronimo to battle against Sachira, but then summoned Amil Gaoul to double-team Noa. Just when it seemed that Noa was defeated, Hugh was overcome with intense pain and regurgitated Amil Gaoul's shard. Noa, mentioned that Amil Gaoul had rejected Hugh, and the pain he was feeling was his punishment. Before he could be captured, Hugh teleported away, back to Zymot.

Hugh's fake death

After returning to Zymot, Hugh stopped wearing his mask and revealed his true face, a menacing, devilish visage. It seems that the after-effects of having Amil Gaoul have also twisted Hugh, making him slightly insane. He has recently begun an invasion of Neotopia along with an army of Tusk beastmen.

Zed hits Hugh with a shard explosive and then stabs him through the torso. Pronimo and Amil Gaoul return to their owners as Hugh drops dead, revealing a face clothed once again.


Kiba

She has black hair, which she wears in two ponytails, and dark pink eyes. She wears a short yellow coat that exposes her abdomen. She wears white long pants with two pouches. Later on she develops horns coming out of her shoulders, a sign of her Tuskan heritage.


Kiba

Zed is a young man in his mid-teens. He has a white hair color and dark green eyes, as well, as highly attractive. Zed also has dark rings under the bottom half of both his eyes, it could possibly some kind of marking representing shard casters like the green clover on his friend Mikki's right cheek. Before he travels to Templer, he is shown to wear a sleeveless jacket along with a yellow shirt and black pants. On his left waist, he has a golden medallion with two feathers that has been given by Noa to Zed on his birthday. What is the most unique characteristic of Zed's red coat is that his left arm is sleeveless, compared to his right arm. Presumably, since his Shard mark is on his left hand, then it is quite easier for him to draw Shards if he has no sleeve on his left arm.

A young man who has a brave and a rebellious nature. He is 15-years old and originally from Calm, a land where no wind blows. He is shown to be a delinquent and a rebel at school. Because he has a tendency to break down doors and gates, he has been on the run from the police and his school teachers. It was shown that Zed once took on some older kids all by himself when he saw Noa was being bullied by them. Zed tends to be cold to others, and he speaks quite harshly at times even to people older than him, like Elder Jiko and Sebastian . Zed possesses a strong will, and openly defies things that are useless in his perspective. He would rather sacrifice something for the greater good, to save many lives and people who are important to him.
He is a good and loyal friend, and comforts Roya and Sagiri when they are in pain throughout the series.
He can be described as an impatient person and a hothead, and can sometimes be naive. His reckless behavior and personality can also be seen in his battles, where he charges and fights against an enemy Spirit on many occasions with only his Shard sword. He is shown to be adept at battle, and has defeated many powerful foes throughout the story. However, he does not fight and kill people without reason, with the exception if they are enemies. He dislikes bloodshed, and he desires to stop all the warring so no more innocent people can be killed by the greed for power.
At first, Zed wishes to become stronger, but as the story progresses, he doubts that only being strong is enough for him. He thinks only becoming stronger is somewhat lacking on its own, which contradicts his behavior earlier in the story where he vigorously searches for power.
Despite his behavior, Zed has been chosen by the strongest Key Spirit ever known, which is Amir Gaoul. What Zed and his Spirit, Amir Gaoul have in common, is that they are both rebellious by nature, and that they both possess great power. Zed wishes to end bloodshed, and Amir Gaoul seems to share his opinion, with the both of them working together to stop all the useless fighting.

Eclipse is the Chief of the G.O.T.T. . Her job is to ensure normal economic activity on all of the planets in the Galaxy, she operates, to an extent under the guise of the Galactic Union. Mainly she ensures this by sending of various groups of people or ES members to either fight, arrest, seize, destroy or assist in order to achieve the goal of normal economic activity. An ES member cannot disobey a direct order from Chief Eclipse, and by doing so this results in a Purge order. For instance in Episode 1 she sends a Letter of Attorney to allow trade to pass to Faunus and Medea (a military blockade stops this), in Episode 2 to stop illegal production of High G a gravity control material, and thus to allow normal production. In Episode 3 they must escort prisoners in charge of extradition back to the G.O.T.T. head office.
In each of these instances she sends out an ES team. She never gets directly involved. Though in order for the members to make an arrest they must seek permission through her. Her true job, and what she spends most of her time doing, is never clear. Her superior is Chevalier D'Autriche and her secretary is the number-crunching expert Mercredi .
Later in the series when there are odd, potentially evil, goings on at the GOTT, it is assumed to be from her. But she is only a pawn through which those at work act, as she has no choice but to obey her superiors.
Eclipse's personality is one of collected calm and eloquence, for this she is greatly admired by Éclair . She rarely speaks her mind and if so it is out of obligation too. She never says a word wrong and smoothly operates the G.O.T.T.. Even in anger she is reasonable, but when she is expected to carry out actions she doesn't often do them willingly, another indication that she never speaks her mind. She is also caring towards the teenagers who are the ES members. She often says something along the lines of "I will be looking forward to your safe return." Her other catch-phrase is "Eclair, Lumiere, arrest authorization granted."
Eclipse is an ES Member herself, contemporary with Eclair and Lumiere, and her G Class ability is known as "Kvant" (Russian for quantum). It is this ability that enables the ES-Members to be 'reborn', as she is able to quantize the soul itself and transfer it from body to body in a process called encoding. She is also able to perform quantum jumps, or teleportation, over short distances.

Tweedledum is a physical sixteen year old and probably the second shortest male of the E.S Unit. He has short black hair, though his right bang hangs over his face and slightly passes his chin, and has red eyes, these parts of his appearance also don't change from Kiddy Grade to Kiddy Girl-and, like the rest does.

Not much is shown of Tweedledums personality, only that he seems to be the calmer one of the twin duo and that he deeply cares for his sister and partner Tweedledee (it is hinted that he got a sister complex). He also tends to get jealous when Tweedledee shows interest in other people, like Lumiere, or Tweedledee pays more attention to someone else than to him, like with Ascoeur. Despite that he isn't shown to be really sociable with others, there are moments where he is shown to care for others. Like in Kiddy Grade as Lumiere was sick and he was visiting her with Tweedledee, he told Éclair in his own way that he too hoped that Lumiere would get better.
It is also hinted that he has trouble or doesn't like to restrain himself while on assigment, as Tweedledee once called him out on in, telling him to use some restrain.

She wears the same uniform and wig as Mercredi, so Vendredi looks very similar to her predecessor.

After the time skip in both the anime and manga, he grows his hair up to his shoulders.

Kaoru is an extreme introvert and socially awkward teen with a habit of throwing up when under stress. This is due to him moving often as a kid making him incapable or not wanting to form bonds with others. This may have been reinforced by the somewhat unwelcoming nature of his extended family (whom he is staying with).

Because of this, he is shunned by his grandmother. He is then raised by his uncle and aunt whom he regards as his father and mother. However, this story is untrue, as the priest at the church tells Kaoru Nishimi more about Sentarou's background after his disappearance. He states that Sentarou was abandoned at the church (thus the reason his birthday is on Christmas day.) until he was three years old. The story about Sentarou's uncle and aunt taking him in was just a lie to convince his grandmother to let Sentarou stay with them. The reason for this is because his grandmother hates the Americans. Though the priest says the story could be true, as Sentarou's father's sister had worked with the Americans, and had gone missing a few years before Sentarou was found. Despite this, no one knows the truth.


Kids on the Slope
