Tenko Chabashira

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" (replacing part of the normal word for boys with the kanji for death in the original Japanese) 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.

Hyperactive and Expressive: Tenko wears her emotions openly, yells to display her fighting spirit, and reacts impulsively to her environment. [1, 2, 3]

Strong Misandry: She harbors an intense, vocal dislike of men—frequently calling them "degenerate males"—and reflexively throws any man who touches her, a trait taught to her by her aikido master. [1, 2, 3]

Jerk with a Heart of Gold: Beneath her loud and abrasive attitude toward men, she possesses a pure, deeply protective nature, caring deeply about justice and the safety of her classmates. [1, 2, 3]

Devoted and Loyal: She forms an intense, affectionate attachment to Himiko Yumeno, supporting and protecting her unconditionally. [1, 2, 3]

Action-Oriented: As the Ultimate Aikido Master of "Neo-Aikido," she relies on physical movement, instinct, and loud declarations rather than deep, calculated strategizing

Tenko is a boisterous and generally cheerful person. She wears her heart 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. She seems to panic in a Class Trial if suspected of being the culprit and tends to react strongly humorously. In the demo version, when Kaede talks to her after the murder, she immediately panics as she assumes she is being suspected.

Tenko and her master developed a new style of Aikido named the Neo-Aikido. Different from the original teaching of Aikido, the Neo-Aikido that Tenko invented is more aggressive and has many offensive techniques. Tenko even believes that the only true way of training for Neo-Aikido is actual battle. However, in reality, Neo-Aikido was only invented in order to control Tenko's over-activity and anger issues when she was a child.
