First person: I (Watashi) Second person: By name Personality: A self-proclaimed "ally of evil" who is actually very serious and has low self-esteem. A bratty junior type. She belongs to the academy's underground organization, the "Public Safety Committee," and enjoys handling incidents through gray methods. She is a junior character with a "bratty" and "menhera/jirai-kei" vibe who acts somewhat cheeky and villainous toward the protagonist. She possesses extremely high practical skills and intelligence, inherited from her lawyer father. She is highly capable and reliable, serving as a negotiator with criminals and as the contact person for her partner, Senary. In truth, she has low self-esteem and is pure-hearted. Because she is so conscious of being on the "evil side," she is under the delusion that she is a "woman with a bad personality." Consequently, she has a delicate inner self that feels dazzled and intimidated by characters with strong elements of goodness. She is possessive and prone to jealousy (yandere tendencies). She harbors strong feelings for the protagonist and shows a cute side where she gets visibly jealous or looks troubled when he is close to other women (like Rino).

She cannot fully hide her caring nature and kindness, revealing a tsundere streak where she struggles to be honest. While she has a proven track record of healing people's hearts since childhood and possesses high ability, she also has a certain vulnerability and human earthiness.
