School: Trinity General School Club: Justice Task Force / Make-Up Work Club Year: 1st Year Age: 15 Birthday: April 16 Height: 148cm Hobbies: Fantasizing, daydreaming, collecting lewd magazines A first-year student at Trinity General School. Originally a member of the Justice Task Force, she was transferred to the Make-Up Work Club after failing to skip a grade and facing the threat of repeating a year. She holds a dual position in both clubs. She deeply admires Vice President Hasumi and reacts honestly to her. She reacts excessively to anything lewd, shouting "No! Lewd things are forbidden! Death penalty!" Regarding Sensei, she is always on guard, suspecting that whatever they say is a pretext for doing something lewd. Her eyes turn into cat-like slits when she's flustered. While she has many openings and is depicted as being weaker than even mob characters in combat, she possesses a strong sense of justice and a conscience that isn't swayed by the atmosphere. As a result, many students have been saved by her convictions. Not only her fellow club members and Hasumi, but even Mika—who was saved by her brave actions—hold her in high regard. Her support base is growing behind the scenes without her realizing it. Anyone who tries to harm her would likely be erased by the dangerous individuals of Trinity. She is a rare student with moving wings not just on her back, but on her head as well. While others have wings, Koharu's flutter according to her emotions and she even uses them to cover her eyes. She is currently the only member of the Justice Task Force with pink, wavy hair (other members, named or not, have straight black hair). Furthermore, she wears her uniform with the left shoulder exposed and sports loose socks, despite her constant nagging about public morals. She called Female Sensei "Big Sister," but the Cronos School Journalism Club broadcasted it to the whole world, leading everyone in Kivotos to start claiming they are Koharu's sister. She addresses the Tea Party members with high honorifics.

Responsible for personnel matters within the committee, she is admired for her attitude of being strict yet kind while looking after all members. Both her wings and chest are outsized; she has the largest wings among all winged students, let alone Trinity students, making it impossible for her to get lost in a crowd. She has red eyes without highlights and a beauty mark under her left eye. For some reason, she is claiming to be Koharu's mother.
