Ruka is a slim, fair-skinned man who stands at average height. He possesses long, straight teal hair with dark blue highlights, styled with the bangs fanned out to the side resembling fins and two long strands framing his face, with the rest separated into four strands reaching past his thighs. He has purple eyes with gold rings around the pupil, adorned with thick teal eyeshadow and prominent lower lashes. His nails are teal.
Despite no longer being a guard, [2] Ruka wears a slightly modified version of the standard Nanba Prison guard uniform consisting of teal and dark blue shawl worn around his shoulders and decorated with a hexagonal pattern resembling scales. His hat is decorated with three gold, hexagonal accessories and, Instead of the standard red belt, he wears a dark blue belt tied into a bow in the middle and decorated with pale blue beads. He wears a necklace comprised of large, dark blue beads resembling Buddhist prayer beads, and a pair of dark blue boots decorated with a gold diamond pattern.

Ruka has a calm and composed exterior but is also bold and sadistic, seeming to find entertainment in tormenting and punishing those who get in his way. [3] He is highly persistent and aggressive in his attempts to take down his opponents but rarely fights with his full strength straight away, indicating a certain amount of pridefulness and arrogance. He is rather manipulative, willing to take control of former coworkers in order to meet his ends, and states that he enjoys learning other people’s secrets despite having no other interest in those around him. [4]
Ruka is characterized by his idolization of Enki Gokuu , believing himself to be closer to him than anyone. He adores him to the point of imitating his mannerisms in the hopes of bonding to him, including repeatedly insisting that no one will understand what's on his mind. He holds the belief that everything Enki does must be right, including the act of murder; this has resulted in him attempting to kill to meet his ends with no hesitation, justifying his illegal actions by stating that Enki is a murderer as well. According to Kiji Mitsuba , this is because Ruka, like many residents of building five, has a habit of acting without thinking. [5]

Ruka frets about his makeup during an intense situation

Despite claiming to be dissimilar to his rival Kiji, Ruka shares many traits with the supervisor to the point where many see no difference between them. [6] An example of this is that he is a remarkably arrogant individual who takes an immense amount of pride in his appearance, often worrying about it during serious situations; [7] during battle, he habitually opts for waterproof makeup so that he can come into contact with water without ruining it, indicating his vanity. [8] In addition, he once considers betraying Enki in exchange for some high-quality makeup. He also shares Kiji's short-temperdness and bossiness, being quite demanding of others and quickly losing his temper when he isn't taken seriously [9] or if his appearance isn't up to his standards. [10]

Samon is a slim young man of below-average height. He has lightly tanned skin and slicked-back curly orange hair that has green bangs at the bottom on both sides; when he was younger, he wore it long and tied into a thin braid. [4] His eyes are green and outlined with red makeup; additional red makeup is dotted at the corners of his mouth. He wears two silver, hoop earrings in each of his ears, and his arms and legs are covered in red sleeve tattoos featuring numerous spiral patterns. His nails are painted light green.
Samon wears a slightly modified version of the standard Nanba Prison guard uniform. He wears round, red, and gold shoulder pads instead of rectangular ones, and his belt is fastened with an oval-shaped buckle; attached to the back of his belt is an ornament resembling a monkey's tail, which is red in color with a white tip. Instead of being black, his boots sport a red and black camouflage pattern and have green and gold trimming. He wears spiral-shaped pins on his collar, and his hat is decorated with a gold headband instead of the Nanba Prison symbol. As a guard of building five, he wears a dark green armband on his left arm.

Like many residents of building five, Samon is a competitive, energetic and feisty individual. He is very dedicated to his training and has been since childhood, [5] harboring immense pride in his abilities to the extent that it borders on arrogance; while fighting an opponent he deems unworthy, he does so while closing his eyes or using only one arm as a means of "engaging" them. [6] He regularly subjects his inmates to training as a form of both rehabilitation and punishment, [7] [8] and claims that his building is the most disciplined as a result. As such, he largely considers himself to be the superior of all of the supervisors. [9] He is very disciplined and diligent himself, and subsequently has little patience with lazy or frivolous people. [10] He is noted to be rather childish and has a short fuse, regularly losing his temper over insignificant things such as the mention of his weaknesses. [6]

Samon admits to his faults

Much of Samon’s pride seems to stem from a significant inferiority complex that he harbors towards Enki Gokuu , who spent much of their childhood informing Samon that he was weak. [11] As such, he regularly refuses to admit to his losses or weaknesses [6] and sees any offer of help as a personal insult, resulting in him stubbornly taking on all tasks by himself to the point that his subordinates often worry about his health. [12] He is ambitious and quickly becomes frustrated when he isn’t as strong or dependent as others, [13] wishing to be the strongest of those around him in order to both defeats and protect them, [14] Eventually, he openly characterizes his own pride and ambitiousness as mere greed and petty lies, showing a surprising amount of maturity by reconciling with his flaws and asking his coworkers for help for the first time
Samon is dedicated to his job and often takes it upon himself to try to unveil his coworker’s misdeeds [15] or otherwise enforce the rules in the place of his boss. [2] He himself asserts that he is the superior supervisor and has never permitted an inmate to escape, further displaying his arrogance. [9] Befitting of his feisty and energetic nature, he is quick to pick fights with others. [2]

Scara B. Kepri is an egotistical individual. Since he is the only God in flesh and blood and not a reincarnation this gives him a unique arrogance, and also an inexhaustible power .

Seitarou wears the standard Nanba Prison guard uniform with no alterations. As a guard of building thirteen, he wears a red armband on his left arm.

Seitarou has a reserved, soft-spoken personality. Unlike the majority of his coworkers, he is rather meek and timid in nature and can be easily reduced to tears. As a result, he finds it difficult to be taken seriously and is often bullied by inmates, who seem to have little respect for him despite his position of authority. [1] As a result of this regular bullying, he tends to be highly surprised and touched when others behave kindly to him to the point of being moved to tears. [2] Befitting of his shy nature, he seems to dislike confrontation and, instead of disciplining inmates, resorts to attempting to befriend them to avoid their teasing. [3] He is rather lacking in self-confidence and believes himself to be unworthy even of simple tasks such as looking after an inmate’s belongings, [4] much less disciplining them successfully.
Seitarou is shown to be a kind, polite person, even towards inmates and his juniors. [5] He seems concerned for the inmates’ wellbeing, as shown when he picks up on Jyugo’s downhearted state following his encounter with Elf and attempts to find out whether something has happened to him. [6] Despite his timid nature, he does, on occasion, attempt to stand up for himself and shows a certain determination to do well in his job, often doing more than necessary to help others and make his job easier.

He highly takes pride in his appearance and believes to be "handsome", making others refer to him as "Prince" or "Shin-sama".
He's also rather jumpy, as seen when speaking with Kiji Mitsuba and abrasive when he blatantly interrupted a moment of rareness between Kenshirou Yozakura when he almost got his head patted.
Despite these antics, his mood can change from polite and silly to downright cunning; knowing the information of events going on in the male side of Nanba Prison even though he doesn't travel there often. He's also deceptive and can be cold when he feels necessary, making him a dangerous person.
He also doesn't mind giving out tips to becoming attractive. If someone's interested in being popular like him, he'll give them information, as long as they admit they aren't better than him.

After events occuring in the second New Years Tournament Sith is shown with two scars across his face.

Sith is a shinigami cultist, actively seeking out others to believe in the shinigami through recruitment posters, becoming disinterested and annoyed when the other party isn't interested in becoming a believer.
He is also a selfish individual, using others as a way to recruit shinigami believers, which can be seen when he deceives Koisuke Kyuubi into purchasing a shinigami charm that can 'alter' Koisukes marriage prospects. [2]

However, at times he participates in the nonsense others do. He’s shown to be loyal and like an ‘honor student’ around Isou , who he looks up to, but, around the others he is shown to be harsh, rude and bratty. Despite this, he can be considerate.
He is shown to be ill-mannered when eating the cream puffs that Mei and Ido made, shoving it into his mouth and making a mess by getting it everywhere and not cleaning it up afterwards. He’s keen to sticking his middle finger up, showing his temper and short fuse.

Taura is a tall, curvy, and attractive woman with abundant spiky white hair of varying lengths, the longest clumps reaching down below her waist, which somewhat resembles a pine tree in shape. Two swept tufts of her hairpieces curve to the sides. She has sky blue eyes that tilt downwards in the center, framed by a set of rather long white eyelashes and faint freckles sprinkled across her nose and cheeks. She appears to have a white tail with a red ribbon tied at the end.
Her clothing is similar to a pin-up cowgirl; a 'cow' printed bra, which emphasizes her breasts, a dolly jean shirt tied under her breasts, and cow-printed cowgirl/boy style pants with holes cut out around her upper thighs. Along with black short shorts, she wears a white thong with the strings pulled up to the top of her hips. She has a cowboy hat with the zodiac medallion on the front, black gloves with stars cut out that most of the Zodiac Police members wear, and a brown belt decorated with gold studs, a matching zodiac buckle in its center with fringes on it with a cow tail strapped on her bottom. She also sports a red ribbon on her neck with a cowbell tied in the middle.
In the more recent chapters, her cowboy hat is now black instead of blue, adorned with a red band and a silver medallion of the zodiac sign she was based off, Taurus, in the middle. She wears a brown & black crop-top style jacket adorned with silver studs, and a red belt with a buckle that matches the medallion on her hat.  Her pants have a similar cut to the one in her previous outfit, only now the cow print is replaced with all brown, decorated with fringes on the sides and silver studs. She appears to not wear a white thong anymore, and her black fingerless gloves no longer have the star-shaped holes on the back (most likely because it is implied that she is no longer part of the Zodiac Police [1] ). The ribbon around her neck is a darker shade of red, with the ribbon now tied on the side with no cowbell.
She still wears a cow print bra and black short shorts.

Taurus is a very prudent and dedicated person who acts as a natural leader and is generally level-headed and calm in dangerous situations, but she isn't above falling into a panic. Taurus can be blunt with her comments about people's mistakes and miscalculations, tending to be very honest and wishing to help her peers improve enough to become great, like furthering an investigation. Taurus shows further development as a selfless hero who gets inspiration from her brother, realizing the important thing is to focus on saving her and help them out at that moment, even if it means losing her life.
Despite her semi-serious attitude, she also is quite bubbly and shameless. But there are times when she can be shown to be serious and brave as she went to go retrieve her brother's body from Ceremony.

The sweater has red and gold trimming and gold zips on the sleeves, which cover his entire hands in a manner resembling paws. He wears pastel blue boots decorated with gold and red trimming and pink polka dots, and, as a guard of building one, he wears a pink armband on his left arm.

Tomato initially appears as bubbly, outgoing and approving, not hesitating to complement an inmate’s achievements even when their actions are against prison rules. He himself seems to have little regard for the rules, regularly attempting to contact inmates from buildings other than his own despite having been forbidden from doing so. He is also quite childish, resorting to juvenile pranks as a means of revenge against those who irritate him [7] .  He possesses an insatiable curiosity and is willing to travel great distances across the prison on foot for a chance of finding out information.
Despite his friendly persona, Tomato is a highly volatile and capricious individual prone to mood swings. He has the potential to, without warning, develop a much darker, sinister and irritable personality, especially when he doesn’t get his own way. Described as “eccentric”, he has an ambitious nature and is obsessed with invention and research, traits which are often considered out-of-place for a prison guard [8] .

He sports a black and purple tool belt with a pouch containing various tools resting on each hip. He also wears red boots. His ID badge is pinned to the left side of his chest.

Like Honey, Trois is a cocky individual with a great amount of confidence in his appearance and abilities to the point of vanity, considering himself to be the best looking man in Nanba. In contrast to his cellmate, however, he is a calm, warm and friendly individual. He rarely bears a grudge against others [1] and is nearly always seen smiling. He is kind and gentle to others and, despite his somewhat arrogant nature, won’t hesitate to compliment other people’s abilities. Trois loves women and seems to be highly popular among them; his interest in them borders on perversion as he regularly asks about their underwear, specifically bras, even if the woman is a complete stranger. [2]

Trois is a talented mechanic who is fascinated with machinery such that it borders on obsession. He will instantly dismantle and steal the parts of anything that captures his interest, displaying a certain amount of impulsiveness. [3] He shows great enjoyment in making dangerous weapons and comes across as somewhat sadistic, showing no remorse at harming even his own allies with creations. Ironically, he regards the stealing of the parts to make such weapons as the most immoral part of his actions. [4]

Beneath this, he wears a much tighter, black jumpsuit that covers his entire body, with a mask that can be pulled up to hide his lower face. He wears red bands around his wrists and ankles and sports a thin, black and gold band around his forehead. His ID badge is pinned to the left side of his chest.

Tsukumo is portrayed as a cold, rigid and aloof individual who expresses little emotion. He is unfriendly and displays a great amount of pride in his abilities that border on arrogance, boasting about his talents and accomplishments while mocking the abilities of others. [8]

Tsukumo tries and fails to behave naturally

Tsukumo's haughty exterior hides the fact that his acting career has made him significantly awkward and timid. [9] He describes such traits as the result of an "occupational disease" that he doesn't wish to acknowledge even to himself, posing as his trademark uptight shinobi to avoid people seeing his self-consciousness. [10] Due to the fact that he has spent the majority of his life acting, he has a poor grasp of his real personality [11] and, despite being able to act whatever role is required of him with great precision, is unable to behave naturally. He often aims to imitate others [12] and believes that he is only loved or wanted due to his talent and acting roles, leading him to become rather lonely. [13] After revealing this to Jyugo, Tsukumo decides that he should strive to be himself during his incarceration in Nanba [14] and, though he routinely struggles to do so, becomes a warm, friendly and kindhearted person who values his friends. [15] He is a highly polite and formal person, frequently addressing others with the respectful honorific "-Dono". Like Yamato Godai, he is passionate about Japanese traditions and culture [16] and is dedicated to his training. [17]
Tsukumo appears to have a strong distaste for lying, leading him to resolve to quit his acting career and follow his own path without utilizing any form of deception. [18] Despite this, he still cares greatly about his many fans and frequently worries that they will be disappointed in him if they find out he is in jail; as a result, he tends to panic whenever he is recognized [19] or if he fails to maintain his character as a shinobi. [20]

Uno is a self-proclaimed “pretty boy” young man of above-average height. He is rather well-built and has ankle-length, blond hair with deep pink streaks, worn in in a thick braid with short, messy bangs framing his face. He has fair skin and blue eyes with long eyelashes and thick eyebrows. He wears blue stud piercings on his ears [3] and sports dark blue tattoos on his back and left arm; the number 1 is tattooed in dark blue on the back of each of his hands, forming his ID number 11. His nails are blue.
Uno wears a blue-and-white striped inmates' jumpsuit worn with the top entirely undone and the arms tied around his waist, exposing a black vest top. He wears a blue-and-white striped arm warmer on his right arm and a matching cap decorated with gold pins forming his ID number, eleven. Around his neck is a silver dog tag necklace. He wears black boots, and his ID badge is pinned to the left side of his chest.

Uno takes a great amount of pride in his appearance and is very confident in his abilities, often exerting a certain amount of vanity; he considers himself highly attractive and popular. This is exemplified by the fact that he puts a considerable amount of time into getting ready each morning, as well as arrogantly “predicting” which of his inmates will be popular. He can be quite blunt and tactless in nature. Despite his superficial attitude, he is by no means selfish and is portrayed as a kind, warm, friendly, and extroverted individual who cares greatly for his friends. He understands them well and is willing to accept them for who they are no matter what, as shown when he voiced his fondness and approval for Jyugo despite pointing out all of his flaws moments beforehand. He’s a thoughtful person who is willing to give his friends advice, though he puts no pressure on them to tell him what’s on their minds.
Uno is described as a rather cowardly person who is easily scared. For example, while exploring the Gogyousan Underground prison he becomes terrified of the Jiang Shi dolls used to patrol the area, such that his friends initially wouldn't tell him they were there lest he became too scared to come with them. [4] Despite this, he has little problem standing up to danger, as well as challenging figures of authority, [5] for the sake of his friends.
Uno is a compulsive gambler and, because of his gambling experience, has developed not only a habit of cheating shamelessly but a high level of intuition. He is able to pick up on the habits and body language of others and uses this information to see through their movements and actions; these skills make it easy for him to win various types of fights, causing him to become rather arrogant. He views gambling as a hobby and greatly enjoys playing games with others, indicating his extroverted nature. [6]

Upa is thin and has a notably short stature, to the point that he could quite easily be mistaken for a child. He has white skin and gray eyes outlined with gray makeup. His hair is teal blue in color and has bangs that curl out to the sides, while the strands at the bottom curl in towards his neck.

He also wears a blue and red Chinese cap, attached to a yellow talisman hanging over his face, and bears the Kanji for his ID number, written in red. He wears plain black shoes, and his ID badge is pinned to the left side of his chest.

Upa is a rather serious person with a calm exterior, rarely showing much emotion. Like many residents of building five, he is shown to be prideful and has great self-confident in his abilities - he openly regards himself as a "gifted master" of qigong and refuses to share his techniques with those he does not deem talented enough, coming across as arrogant at times. [3] He is quite ambitious, prioritizing his goals above anything else and refusing to concede to anyone. Befitting of his prideful attitude, he is reluctant to admit being unable to do a task and cannot stand losing; he will instantly fly into a rage if he does so, exhibiting a child-like temper that differs from his mostly mature temperament. [4]
As a person who is willing to work hard to achieve his goals, Upa has a low tolerance for lazy and frivolous people and is very impatient with them. He can be very forthright and often harsh to such people, often seen referring to his cellmate Qi as "scum" or "trash"; he is shown to be downright rude at times, not only to fellow inmates but even prison guards. [5] [6] Despite this frequently cold and brusque attitude, Upa has proven that he is capable of showing compassion and concern towards others, as shown when he prioritized Nico's safety over his own during his battle with Hachiman. [7]

He wears a modified version of the standard Nanba Prison guard uniform: he has a hat which has a golden trident-fork shaped object sitting on it, two black straps each on different parts of his body including his left arm, both sides of his waist and his thighs and and the lower parts of his legs, pointy black shoes and an additional red cape. As a person in charge of building 6, he wears a grey armband on his right arm.

V is overall a polite, respectful and welcoming person to his fellow coworkers and even inmates. Many people have described him as "gothic" which leads to the unfortunate situations experienced throughout his life. He is sad of hearing this, but he doesn't get angry about it. Because of his troubling past, V has a very strong sense of responsibility that can sometimes make him obsessive and lose his mind, to the point of burying himself alive.
When he fails to serve his master or they get even slightly wounded, V  gets in a crazy sado-masochistic state that makes him go on a self-hate rampage and attack who ever harmed his master. He thinks he should die for his mistakes and suffer the worst faith ever for the sake of failing is master. When he feels or undergoes any kind of pain, he gets extremely excited and ask for even more of it.

He has rather messy, dark blue hair with multiple strands falling over his face. Surrounding his neck and arms, he carries several white snakes with red eyes.

He wears teal boots decorated with red ribbons and lighter colored, swirling patterns reminiscent of clouds. As a guard of building eight, he wears a teal armband on his left arm.

Orochi is pessimistic and has a fear of social interaction. He is very self-critical, worrying about how his creations would appear to others because as an artist, he demands a lot from himself. In spite of his negativity, he has an extremely large passion for arts, to the point where others see it as almost an obsession. He approaches and talks to people who show an interest in his work and is very friendly to them, a great difference to his usual behaviour.

Yamato is loud and simple-minded in nature, often seen laughing heartily. He is air-headed and clumsy, regularly bursting into both staff rooms and cells in a destructive fashion with little regard for the consequences; [2] [3] even Nico refuses to trust him with his belongings despite his high status as a guard, convinced that he will break them. [4] He is absent-minded and has a poor sense of direction, often being late due to losing his way within the prison. He has been known to rely on inmates to find his way on occasion, [5] suggesting that he doesn’t care much for his pride and respects the inmates beneath him. He is a rather polite and formal person, referring to others with the respectable honorific “-dono”.
Yamato is characterized by his love of training and exercise. He is passionate about it to the point of neglecting his duties in order to train, and regularly has inmates partake in his workouts with no regard for their blatant lack of enthusiasm. [6] In spite of this, he is not the least bit aggressive; he prefers to take the most peaceful route possible during battle [7] and is warm, friendly and compassionate towards others.
Yamato is a highly patriotic individual who indulges in Japanese culture with great enthusiasm. [8]

Zakuro is rather childish and quiet. He is unused to socializing, which results in him being nervous around others. He is also a rather paranoid individual, believing that everyone around him is apart of a group of people out to get him. Before Jyugo convinced him to stay at the prison Zakuro was hopeless, believing that he had no future nor the ability to obtain what Jyugo had gotten so easily. [2]

Nano List

She has dark gray hair and pink eyes. She has been described as beautiful.

She was known to be confident, straight forward, a bit psychotic, foulmouthed and displayed a lack of empathy towards others including Milo. However, she reflected on the devastation her creation was capable of and questioned her judgement after Milo was attacked by Chacha 's Androids. She even eventually chose to sacrifice her own life to protect Milo and ensure that the Nano List technology was not compromised.


Nano List

Her appearance is similar to that of a child as she is often described as "young" and "small". She has short dark hair that stops at her neck and her height is petite compared to other androids. She was first seen wearing a ribbon so that she could be distinguished by Milo as his 17th birthday present. She is often described as 'lovely' and 'cute' which was how Dr. Maddie Ahn wanted her to be.

Nano finds Milo to be annoying and daft but cares deeply for him. According to Milo, she is similar to San in many ways. He finds them both pretty but foulmouthed. Everyone believes she picked up the latter trait from her creator .


Nano List

San is an attractive Android with an hourglass figure. She is quite tall, having a height of 181cm. She has long silvery-white hair which is usually combed back and pink eyes. She also has a tattoo just below her left eye, saying " +BEAUTY+ ". San wears black leather gloves when fighting, to stop the skin on her hands from tearing.
According to Milo, San and Nano are the only Androids that he has found truly beautiful.

San adores Milo and often makes sexual advances that leave him flustered. Despite this however, it seems that she does genuinely love Milo as shown in Chapter 26, as she wishes that Milo will not turn out like his sister (who killed herself) and to live his life to the fullest, hoping that she can be on his side forever.
She is often described as foulmouthed, a trait she may have gotten from her creator, Dr. Maddie Ahn.


Natsume's Book of Friends

This youkai is very large and tall. He is entirely black with white eyes, has a petite goatee and wears a purple and white yukata.

A calm youkai at most, the Acorn-Eating Youkai does have a bit of temper and is defensive as he took offense when Reiko questioned why such a large guy like him is eating small scorns.
He claims to dislike humans and like birds as they are not as problematic. However, he can show fondness towards humans (Reiko and Takashi, for instance) if he finds them intriguing or different. He is a helpful youkai, even going as far as protecting Reiko from Kayatsubo's wrath and informing Takashi of Kayatsubo's reason for her rage.

A kind youkai, the Ancient Tree Youkai had taken a liking to Tooru Taki , and does not seem to despise humans, although that does not mean he has a liking to them, either.
It is as if he is inquisitive about humans as he has been around them for many years, but never had the chance to interact with them, until he met Taki and Takashi Natsume .


Natsume's Book of Friends

Aoi has dark blue hair and blue eyes. He is often seen wearing a school uniform with a white collar shirt with a loose sky blue tie and black pants. From time to time, he can also be seen holding a lollipop. He has dark blue bird wings sprouting from his back the same color as his eyes.

Aoi can be considered to get flustered easily when it involves Kaoru. For instance, when he had dropped his letter and Natsume had picked it up for him, he had gotten nervous and took it back, saying he hadn't even realized he had dropped it.
He's also rather kind, even to consider the fact that Kaoru was a human and that he was a youkai and that they shouldn't be together or have mutual romantic feelings for one another.
Likewise to a human, he does display signs of selfishness such as finally wanting to let go of Kaoru by seeing her get 'married'. He also is protective such as attempting to cover for Natsume when youkai had attacked Natsume, Madara and himself.


Natsume's Book of Friends

Aokuchinashi is a shrine god that takes the form of an old woman with gray hair and closed eyes. She wears a traditional pink kimono and covers it with an extremely long, green haori. She carries a long staff to help her stand up and walk and was later seen having a cherry blossom flower in her hair to show off.

As she was a divine being, Aokuchinashi doesn’t have many friends. However, she was extremely kind and gentle towards the things she cares about. Although she was very stubborn and impatient, she became friends with Reiko whom she thought was a youkai. Throughout the story, it was observed that she was also grateful to those who helped her in her problems as it was shown how dedicated she was to find Reiko so she can return the mirror she borrowed.

He has short brown hair and eyes. Additionally, he is also a bit taller than Natsume. He is often seen wearing his school uniform consisting of a white collar shirt and grey pants. In the Winter, he can also be seen wearing long coats and a scarf.

As noted above, Kitamoto is a sensible and rational boy. This can be seen when he gives up on his potential dream career to become a public servant so he can protect and support his family.
He's also rather responsible, scolding his sister, Mana Kitamoto , when she wakes up their sickly father, and when she attempts to buy doughnuts. He informs her that their mother will get mad, but she dismisses this. Another trait is that he pulled over his father's blanket when it had been falling off.
Kitamoto can also be seen as straightforward, humorous and carefree. He tells Natsume that he doesn't have to force himself to hang out with Nishimura if he doesn't want to. At another point in time, when Nishimura accuses Natsume of 'going out' with Taki , he says he'll wholeheartedly support them, resulting in Nishimura's complaints. [1]
He can also be seen as a glutton, stating that he wishes Mana would stop fixating on the shapes in his lunchbox as he just wants it to be full of food rather than creative and cute.
Kitamoto can also be contemplative. For instance, he had been thinking that he could've lost his family and his home, similar to Natsume's circumstances.

With an unbalanced body measure, his head is almost as tall as his body. Because of this particular characteristic, his facial features are very large in size with a small mustache decorating his face and a mole between his eyebrows. He wears a traditional green kimono and wraps it with a red obi belt.
In the Chapter 108 of the manga, he revealed his true, magnificent appearance in the form of a beautiful, white dragon. Although his characteristics are pretty similar to the dragon familiars of Hakozaki , he maintains his notable mustache which is much longer in length compared to his usual form. Takashi also stated that his dragon scales are remarkably stunning and other spirits even regarded them as a sign of good luck during their shedding season.

Not much was truly known about Chobihige aside from the fact that he seems to act politely towards humans and can even ask for their help if the matter concerns their kind. However, being a dragon in nature, he regards himself as high and mighty and views other creatures as lowly and pitiful. Despite of his complex personality, he likes to drink with the other middle-class spirits, particularly the Dog's Circle , as he frequently appears at Takashi's house for a drinking session.

Enkou seems to be a kappa-zaru (a kappa-zaru literally translates to water-imp monkey).

After the death of her lover, she changed into a dangerous and violent person, fueled by rage and hate. She had only one thing in mind - revenge.

Later on, she revealed her protective nature by stating that if Jinbe and Benihimo had tried to attack Yousuke, she was going to handle them by herself. She then opened up to Takashi and asked him to perform the Ritual of Release if that is what the two familiars want— showing that she still have some affinity towards them.

When Natsume first met Hiiragi, she was rather rude towards him, saying that he should mind his own business and that she won't tell him her name (this might be because she had no name at the time but she still made it sound like Natsume, as a human, shouldn't be asking in the first place) and also got irritated at Natsume when he pulled on her rope.
When she speaks, she says exactly what's on her mind, even if it hurts someone's feelings. While she's often blunt about things, she shows a very loyal connection to Natori, mainly due to his kind act of bandaging up her wounded hand when he was a child.

She is proud and looks down on others, although she is secretly kind-hearted. She also has a twisted sense of humor.
Like most ayakashi, she gets bored rather easily and would help Takashi out if he asked and if she feels like doing so. She seems to hate men, though the reasoning behind this has not been disclosed.
However, she has a grudging affection for Takashi because of his uncanny resemblance to his grandmother Reiko . She gradually learns to like Takashi as an individual. This affection grows to the point of strong attachment and deep fondness such that she openly worries for Natsume’s safety, gives him advice and information about yokai, protects him, acts as a sort of mentor, displaying strong affection and cuddling him, and threatening anyone who harms him.

Isamu seems to care little for his appearance as a fraction of his hair falls over the top of his face. Additionally, when he is first seen, he is wearing a long-sleeved shirt that has a bear print and a claw with the word 'SHUTOBOTU' and a small star on the left.
This is further supported by his second appearance as he's wearing trousers, a short V-neck shirt and a jacket whilst casually holding a mug.

Isamu can be deemed as a realist as he doesn't believe that youkai or superstitions are real despite the thoughts of his sister, Tooru and his grandfather. He constantly tries to disprove their existence, even heading into areas that hold old legends. He's extremely determined to disprove them as he even states that on his trip to Mount Kenba he had camped there for several days and when nothing had happened, he decided to investigate the superstitious matter further.
He is also rather straightforward with his thoughts and feelings and can be pretty insensitive, even telling Takashi that even though he doesn't look the part, he must like prying into other people's matters.

As a Youkai, Nezumi seems like a polite and mannered spirit who does not harm others unless necessary. He gave Natsume a subtle warning instead of forcefully trying to claim Tama.
After he failed to capture Tama and Tama turned into an adult, Nezumi smiled, pleased. It may be he didn't want to bring the chick to his master to be eaten.

When she was in middle school, she is shown to have worn her hair in pigtails.

As class president, Sasada acts authoritatively towards her classmates, and can be a bit bossy at times. Takashi Natsume notes that despite her complicated family situation, Sasada is a hard and efficient worker. As shown by how she looked for Shigure in the old school house every day to thank him for returning the amulet to her, Sasada greatly appreciates kindness, and is a very determined person who won't give up once she sets her mind to something. Her persistence is also demonstrated when she frequently follows Natsume around and asks him about what he's doing, possibly because she has feelings for him.

Unlike most youkai Kai is shown within the episode to have near human emotions. He is also known as "Crybaby god" by his worshipers for the frequent floods that spill from the rivers.

He is pretty tall, at least more than the other boys his age in the series, although he's still shorter than adult men like Shuuichi Natori .

Tanuma is a quiet and reserved boy. He often worries for Takashi's involvement in youkai but knows that he can't stop him from helping them. He tries to help Takashi when he can and was discouraged by Madara , saying he was "useless" since he can't really see spirits. In the manga, he desires strongly to protect Takashi and is angered quickly when someone (usually Madara or Shuuichi Natori ) calls him powerless.
Tanuma is also insightful as he notices when Takashi attempts to hide his feelings or tries to protect him as he often sees the hidden meanings beneath the surface but doesn't understand them. This is supported by his curiosity about Reiko when Madara mentions her and his notice of Takashi's reaction.
In the anime, he merely asks because the name was unfamiliar and forgets about it afterwards.


Natsume's Book of Friends

Tanuma's father wears glasses and is bald with a slight beard on his chin. He is most commonly seen wearing black Buddhist robes with a light brown origojyou around his neck.

As a Buddhist monk, Tanuma's father is very kind and understanding. He is a devoted father to Tanuma and had exorcised Yatsuhara, but not out of ill-will towards youkai. It was an attempt to help his son feel better. When Natsume hesitates to ask if he can see youkai, Tanuma's father wisely decides not to press the matter any further and tells him to feel free to come by any time.

He is a gentle and understanding youkai. Karikami is usually calm and didn't get angry or annoyed when he lost to Reiko. He even informed her that he had the power to restore the paper with his name on it should it ever get old. Karikami, like most, was a bit baffled when Natsume didn't order him to restore Yobiko 's letter. Karikami nevertheless restored the paper in exchange for returning his name. He also holds restored paper with care; aware of its fragile nature.

He takes the form of an overweight lucky cat that is round and cute (at least according to him, however, this is also confirmed by Taki [1] & disagreed upon by rest of Takashi's friends). Other characters such as Tanuma , have noted that his head in this form is unusually large.
His maneki neko form is white, with an orange and grey marking on the top of his head and back, black eyes and wears a red cat collar with a gold bell on his neck and has small red markings on his face. [2]
In his original form, he is a colossal wolf-like youkai with white fur, with red markings on his face, and gold eyes. He is extremely large that he can cover Takashi underneath a single paw and a single eye is larger than Takashi's head. Also, in his original form, Madara's voice becomes a lot deeper.
Like most youkai, his original form cannot be seen by people with little or no spiritual energy.

Madara's true form (Youkai form)

He has a somewhat condescending personality. [3] At first, he only protects Takashi for the Book of Friends but as the series progresses, he becomes friendlier with not only Takashi, but Natori , Tanuma , and Taki .

Madara hitting Natsume for his idiocy

His attitude throughout the series can be described as selfish, prideful, and comedic, the way he acts and his attitude becomes the usual "gag" of the series.
He does have an immature and playful side; Madara often drinks himself silly by consuming a lot of sake and loves to eat dango (a Japanese snack) and other sweets, making him heavier and rounder. He enjoys eating in general, often eating fish in the river or stealing Natsume's food at times. When he smells something delicious or hears of a place with good food, he insists that Natsume goes with him so they can eat there. In addition, he is particularly fond of Touko's home cooking.
Despite his protests that he is not a cat, he acts exactly like one, for example, getting excited about cat toys and chasing small animals. He also likes to bully dogs and throws the occasional tantrum.
He has a more caring side to him, which he tries to deny or explain away, but as the series progresses, it becomes obvious that he is attached to Takashi and is extremely protective of him.

Nyanko inside Natsume's schoolbag

Evidence of this is when he went into a rage when Takashi was wounded by trying to protect him in Chapter 26 but Takashi managed to calm him down.
He has also shown to care for Shigeru and Touko as well but yet again tries to explain it away. This is evident is when an angered Kayatsubo began charging towards their home to steal something Takashi treasures, as punishment for failure of returning her doll, Madara immediately transformed into his youkai form and quickly charged back home to stop her, knowing that the Fujiwaras would be home. He remained stationed atop of their home, protectively guarding it until Takashi returned.
He is shown to be acquainted with several youkai, like Tsuyukami , Hinoe , and Benio . His strength and rank as a youkai are evident in his interaction with other youkai who are obviously afraid of him, even in his cat form which was seen in Episode 11 of the anime where he overheard the Dog's Circle talk about him and complain about how he was a fat, tone-deaf, drunk and old cat. Madara got his revenge by summoning lighting which left them stunned and the entire forest around them destroyed.

Her uniform consists of a white shirt with a red collar, a yellow ribbon and a maroon coloured skirt. She had been wearing black shoes and white socks before entering the house.

Mana seems to be an extremely carefree person, even dismissing the fact that she had woken up her ill father. Stating that Atsushi shouldn't worry about him waking up, she proceeded to say a new doughnut place opened nearby and asked her father which one he would like, offering to get some for him.
Atsushi scolds her saying that they haven't eaten dinner yet and their mother will disapprove of this and get mad at her. She also dismisses this saying to not worry about it and that she'll get a doughnut for her too.
Despite her actions, she gets along well with her family and loves them all.

Nothing about its appearance can be guaranteed as it was shown only in its human form.

The Mask-Snatcher youkai was introduced in the episode " Distant Festival Lights " as a youkai that got excited really quickly. It broke into the inn where Natsume and his friends were staying at, after it stole a mask, which controlled the festival, from Ito .

Mitsuzara was originally very bossy and demanded many things from others. He usually didn't carry out any physical tasks himself (with the exception of fishing) under the pretense of being weak, whereas his real excuse was that he was lazy.
However, he soon changes his ways in hopes so that he can join Shuon-sama's troupe, and vows to work and train harder than any other youkai so that he would become stronger.

Both tried their best to understand Takashi and their daughter. However, despite this, they did not reprimand Miyoko for being mean to Takashi. Most likely, though they did not blame Takashi for anything, deep down, they may have found it troublesome.

He possesses a strong will as he once begged Natsume to help him find his student by squeezing the child of man from his back.

That's why he is remarkably grateful for all the letters he received from Azuma when they left the village.

She is an older woman with grey hair and grey-green eyes. As a girl, it was black.
She often tends to wear either traditional clothes or male suits.

A bit of a grouch with an aura of superiority. She seems wise but cruel (especially to youkai). However she's careful.

He is often shown with his back turned, hence, his face is only seen once during both the anime and the manga. He has brown hair that is seemingly slicked back naturally with only several parts of his hair covering his forehead. He has brown eyes although it can't be seen very clearly.
He wears a light navy-blue button shirt that has a collar and a breast pocket. He wears grey pants. He also seems to have a fairly pale complexion, unlike Nishimura, although it's unclear as to whether this is the lighting within the anime or his actual skin colour.

He is deemed as very cold and direct within both the anime and the manga. He is also extremely determined as he is first mentioned by Satoru stating he is studying his practice exams. The second time, he doesn't appear but is in his room, most likely continuing his study to the point that he doesn't even have leisure time for himself. However, it is implied that he may be somewhat observant.
It is during this time that his personality traits are displayed when Satoru invites Natsume over due to his 'anemia' (which is later revealed that Natsume had just encountered a youkai). He becomes irritable, coldly saying to Satoru that he's inviting his friends over while he doesn't have the time since he's so busy.
When Natsume leaves, stating he's fine, he makes several other comments to display that he's observant. He questioned if Satoru had forced Natsume to come to Nishimura household and that he was just being annoyingly nosy. He also says that Natsume gives him the 'creeps' then tells Satoru to not invite Natsume over again.
Afterwards, he is shown to be caring and kind, demonstrating swiftly how to fold a paper crane when Satoru gets stumped whilst teaching Natsume how to do so. This time, he doesn't say that Natsume gives him the creeps. It is unknown as to whether it's because he is aware Natsume is Satoru's friend or if it's because Natsume is presently there.

They are sneaky and determined, seeing as they followed Takashi after failing to capture him, and tossing a jar into his room which imprisoned him in it. All done solely for Omibashira.

Natsume's Book of Friends

Throughout her young life, Reiko physically resembled Takashi Natsume 's (her one and only grandchild and descendant) characteristics through her long, dusty-blonde hair, amber eyes and usually wearing a slight smile, just like Takashi. It is because of their similar appearances that most yokai and ayakashi often mistake Takashi for Reiko. She has been noted to be quite beautiful by both youkai and humans; be they ordinary or exorcists such as her. [1] [2] [3] [4] [5] Her ash-blonde hair was shoulder-length, and usually, it was seen to be unkempt.
She's usually seen only in flashbacks wearing her school uniform, which is sometimes torn. She once had a bruise on her cheek because fearful human children threw rocks at her for being "creepy' and a well-known "harbinger of misfortune and curses."

Reiko was despised by both humans and youkai. [6] She was a bully towards humans and youkai alike, resulting in her being socially isolated. She defeated many yokai and made them write out their names in the Book of Friends , making them "servants" to her. However, there are times she was kind to certain normal humans, but they don't return the gesture. For instance, she had taken a doll from a pot youkai, Kayatsubo to return to a human child, but they told her that she could keep it, believing she stole it.
Initially, her actions were presented as a desire to have control over youkai, but over the course of the series, it's revealed that they were done more out of loneliness and longing for companionship. Despite generally acting apathetic to what other people think of her and, as noted by certain youkai, her expression rarely ever changing from her usual smile, it is indicated that Reiko was actually somewhat bothered by other people's tendency to assume the worst about her, and that in turn, her usual demeanor was something she assumed as a sort of coping mechanism. However, as noted above, she has shown herself to be surprisingly empathetic and kind on numerous occasions where she would help a youkai or another person despite there not being anything for her to gain from doing so. Despite this, most people would still treat her with wariness or disdain, so she often avoided getting involved with them and their problems when she could. Conversely, some of the youkai genuinely appreciated the things she did for them, and on the occasions when she let her guard down, she is shown having genuinely happy interactions with them. This probably strengthened her conviction that she was better at making bonds with them compared to other people, but due to a combination of a lack of social skills as a result of her not having any friends and poor experiences with others, she often went about it the wrong way.
Due to the varying circumstances of her encounters with them, some of the youkai she "enslaved" or made plans with grew to despise or even fear her, while some youkai (like Santo , Gomochi and Hidika ) continued to wait for her return. Regardless of the specifics, she never ended up following up and returning to them like she said she would, indicating she was either forgetful or simply never got the chance to due to dying at a young age.


Natsume's Book of Friends

Amamiya has the appearance of a young woman in her early to mid-twenties.


Natsume's Book of Friends

In his sealed cat form he's identical to Nyanko-sensei except for that his fur is black instead of white. In this appearance, Natsume finds it very adorable (much to the annoyance of Madara).
In his normal state he looks humanoid, except he has blue eyes and hair and is between fifteen and twenty feet tall with white feather wings that have a wingspan twice as tall as he is.
He wears a white yukata with nothing underneath and no footwear.

During his sealed stated - a black, mute Maneki Neko - he is shown to be patient and also enjoys leisurely things (such as bathing).
Much to the annoyance of his followers, he loves humans and was overjoyed when he had befriended one. He is kind, gentle and understanding but also protective. He loves all his followers and while he appreciated their concern for him, he disapproved of their attempt to avenge him by attacking humans. To prevent this eminent attack he stole the Book of Friends from Natsume to lead him to his forest and stop them; this action shows his determination, willpower and love for humans. He also never blamed nor got angry at those who sealed him revealing his benevolence.
Riou is selfless. When he returned to visit his friend, he learned that he had passed long before. This deeply saddened him but seeing as what his followers were willing to do anything for him (including violence acts) he gives up visiting human settlements for their safety, fearing another possible Youkai attack.
