Shiki

Shiki is very stern and passionate about judo, having developed a deep respect for her after being easily defeated by Nagatoro. However, when the girl abandoned her active career in the sport for years, she became offended and bitter towards her, to the point of becoming angry at the very idea of ​​someone she considered a "quitter and returner" being welcomed back into the judo club after leaving, rudely commenting that getting hurt meant not even trying after injuring the girl's wrist in a match and scorning Orihara for forgiving such attitude due to his attachment to the girl because of their past. Despite appearing harsh and spiteful on these occasions, Shiki is often very taciturn and dislikes boasting about her talents or accomplishments. She claims to find it "embarrassing" to be called the "Shitennō" of the women's judo club. She is also very compassionate and generally has a strong moral compass, refusing to report anyone who accidentally broke a rule and even going out of her way to help others.

In her daily life, Shiki is also a very mature and level-headed girl; after realizing she's done something wrong, she is quick to admit it and apologize for it, and is also capable, albeit somewhat reluctantly, of changing her mind after realizing she's misjudged someone. Shikki is also a bit of a tsundere: after realizing her wrongdoing in hurting Nagatoro, she became very concerned about the girl's well-being but dismissed it as an attempt to "make even" with her. When Naoto rejected her offer of help sneaking out of the women's showers, she reacted sadly but tried to act calmly. She is only able to openly discuss her feelings when she is alone with someone. When she was appointed the new director of the judo club, she blushed and shyly replied that she would "gladly accept if everyone is okay with it."

It is also strongly suggested that, despite her toughness around girls, Shiki is, in contrast, extremely awkward when interacting with boys, as she stuttered and acted quite timid and meek while being scolded by Naoto and is visibly frustrated when trapped in a shower stall with him. However, regardless of this, she has stated that she doesn't mind a guy "seeing some of her exposed skin" and is apparently very comfortable with her body, although she is far from completely overcoming shyness at the idea of ​​many people seeing her nakedness. Despite this, she managed to talk to Naoto without any problems as time went on, eventually admitting to being impressed by his courage.

As the story progresses, Shiki began to develop increasingly exhibitionist tendencies, due to the influence of Sana Sunomiya, for whom she has great respect and whose life advice she holds in high regard. Similar to what happened to the latter, her misadventures at school, which led her to fight some thugs naked, eventually made her the source of rumors about Kazehaya High School's perverted heroine, "Masked Nude Girl," an alter ego in which she eventually realizes that she finds exposing herself in public exciting, to the point of starting to enjoy some late-night runs even without a mask.

A natural leader, Shiki is perfectly capable of reacting quickly and planning schemes or solutions under pressure or in tense situations, as well as making decisions naturally, no matter how difficult, distressing, or embarrassing it may be for her. She is extremely helpful, even when someone she barely knows asks for her help. Shiki has had a strong sense of justice since early childhood, is very empathetic, cannot stand bullies, and cares deeply about the well-being of her teammates. Her leadership qualities are universally recognized and appreciated by everyone around her, leading her to be appointed club director by her predecessor. Being very humble and down-to-earth, she nevertheless reacts flattered and blushes shyly when complimented on it.

A recurring gag involving her saw other characters bump into her large chest while running and fall backward, calling it an "airbag."

She has a fair complexion and large, stern brown eyes. She has an athletic, muscular, stunning, and extremely busty physique, along with a butt she considers "too big" and always sports a sad, grumpy look.
