Tenko Chabashira

Tenko is a young woman of average height and a relatively fair complexion, with somewhat broad shoulders and an athletic, muscular build, likely due to her relentless Neo-Aikido training. She has rather thin, wavy, calf-length, dark olive-gray hair tinted with green, peculiarly styled in low twintails tied with white ribbons that bear resemblance to chain-like links, each tail divided into three bunches, each bunch split in the center, the rest of the tail left loose. Her bangs are slightly swept to the right and cut in a choppy fringe, two thin strands of hair left loose to frame her face, the right strand curving inwards and the left somewhat longer, curving outwards. Her eyes are a warm green and sharply angled, two prominent lashes protruding out of the corners. She has a small mole towards the left below her bottom lip. Her head accessories consist of a large, wasabi-green bow with a white floral print resembling a four-pointed pinwheel clipped to the back of her head, and a lilac-purple-pink headband decorated with a paler colored six-pointed star at the left.

Tenko wears a faded blue, cropped, long-sleeved, double-breasted seifuku uniform with two pockets and six white buttons. Her sailor collar and sleeve cuffs are both white striped with a single blue line the same color as her uniform, a white bow tied at her collar. Her previous high school's symbol can be found printed in black at both her sleeves' shoulders. With this, she wears a short skirt the same faded blue as her uniform with two layers of frills, described by Kazutaka Kodaka as a "fashion disaster that shows off the light-heartedness of a sporty girl mixed with the harmonious Japanese essence." It is stated that Tenko added these frills herself to make her uniform more appealing to girls. Her legwear consists of knee-high white socks, the edges striped with a faded blue line the same color as her uniform, and waraji sandals, which she believes to be a common martial artist stereotype. Her accessories consist of a lilac-purple-pink choker the same color as her headband, a silver bell attached. She has E-Cups

Tenko is a boisterous and generally cheerful person. She wears her emotions on her sleeve and has the habit of yelling out in a loud voice to show her fighting spirit. She suffers from overactivity and anger issues and directs her energy into her Neo Aikido. Even still, she claims she is much calmer compared to her childhood. She has also described herself as "not very good at thinking" and appears quite gullible and impulsive, using her emotions over logic. She refers to herself in the third person in the Japanese version.

As a Neo Aikido practitioner, Tenko takes pride in facing the opponent from the front, and she courageously tries to confront the Exisals. Indeed, despite being an Aikido practitioner, Tenko can be very aggressive and quickly resorts to violence, insisting it is self-defense. She takes pride in inventing Neo Aikido with her master. Throughout the game, she constantly threatens guys or Monokuma with her deadly Neo Aikido techniques, saying it is potent. However, she admits that compared to Gonta's incredible power, she had no match for him. She has also admitted that she actually has a very low tolerance to pain and is terrified of the idea of torture. She also occasionally has a panicky side in other situations.

Due to past experiences and her master's irresponsible teachings and anti-romance stance, she feels an intense hatred towards boys, to the point of referring to them as "degenerate males" and openly stating all men should perish. She believes that interaction with boys will drain her Neo-Aikido spirit and thus considers them her enemies. Due to her misandristic outlook, she makes up stories about how bad boys are in her head, such as that boys are much more likely to do negative and deceiving things than girls, like always being the first to lie and always shifting the blame right away. She dislikes boys so much that even the nice things they do can cause her to react negatively. For example, she doesn't like boys praising her. If a boy compliments her looks, her expression will die instantly. She also never allows a boy to touch her, throwing him reflexively if they even attempt to try. Her dislike of boys is portrayed as a very emotional and irrational opinion. There are moments when a boy acts sensible and Tenko feels like agreeing with them but later refuses solely because they are a boy. However, since there isn't much of any actual reasoning behind her dislike for men, there are moments when she seems to completely forget her hatred. She is shown to comfort boys such as Shuichi during moments of distress, doing other acts of kindness for them, and at rare moments, being able to admit that a boy can be a good person. Despite her hatred of men, she can respect them, like Gonta, who is very sincere and deeply cares about his classmates, though she is always surprised and confused by genuinely good boys. Tenko has also implied that she hasn't spent much time with boys in the past, likely because of her master.

Contrasting her hatred toward boys, Tenko likes other girls much more. This also includes trans girls who have had gender reassignment surgery, supported by the fact she wants to shake Shuichi's hand but begs him to have gender reassignment surgery, so she is able to do so. During dangerous situations, she recklessly rushes to protect all the girls, and only them. She also gets very shy and humorously humble if a girl compliments her looks, blushing strongly and insisting that her looks definitely aren't good, and gives excuses such as her face getting all wrinkled every time she drinks from a straw and her eyelids turning inside out whenever she washes her face with a towel. While often assumed to be very tomboyish due to her love for martial arts, she is, in fact, quite feminine, possessing great love for idols, fashion, and cute things. She apparently tries to be fashionable and more attractive to girls with some of her clothing, but she is instead described as a "fashion disaster". She appears attracted to girls, often having dreams about idols and dreaming of becoming a "pampered celebrity" herself. With her love for small and cute things, Himiko is her obvious favorite, and she often admires, wishes to accompany and fusses over her, which annoys the magician. Even though she repeatedly accuses boys of being perverted, she is occasionally shown to be slightly perverted while thinking about Himiko. However, she claims that her feelings for her are only pure and nothing like how males think. However, Tenko is also shown to act embarrassed and panicky if Himiko points out her possible attraction to girls, and she seems to be shy about telling Himiko about it.

As she is so impulsive and reckless, Tenko occasionally doesn't notice other people's feelings and does what she wants instead. However, seemingly as a part of her Neo Aikido skills, she has a unique ability to read the emotions of those she throws. Whenever she does this, she correctly reads the other person's feelings and can give them the right kind of advice. Even when she doesn't throw others, she is occasionally shown to have a calmer moment when she is able to console and guide others and show sympathy even towards boys. Notably, she is shown to get increasingly worried about Himiko, who keeps her real emotions hidden inside and even begins to ignore reality after Angie's "brainwashing." As the complete opposite of that, Tenko believes that expressing your feelings is completely natural, and you shouldn't feel ashamed of them, whether it's crying, laughing, or anger. She is disturbed by Angie, who uses her faith as means to escape reality and doesn't confront her true feelings.

Despite her loud and aggressive nature, she is polite to everyone, even boys, Her politeness is so powerful that it surpasses her hatred toward boys. She also accepts boys to be practitioners of Neo-Aikido out of necessity, though she isn't fond of the idea and just considers them "tolerable." However, after spending time with Shuichi, she begins to believe that Neo-Aikido can, in a way, "purify" degenerate males and make them good people like her master. It's shown that she can even develop feelings for a boy if they are a fellow Neo-Aikido practitioner. However, it's also indicated that this ideal person must also be proficient in Neo-Aikido, noble and not the type who constantly thinks about sex. She considers any Neo-Aikido practitioners her comrades with a bond thicker than blood and is also very loyal to anyone she considers her best friend or a role model.
