Mimori Unyuu

Height: 154 cm
School: Kaimei High School
Class: 2-F (chapters 1-209); 3-C (chapters 210-288)

She is the treasurer of Kaimei High School's student council.

Mimori comes across as a rather flighty young woman. She is almost always smiling and also seems a bit bad at reading the atmosphere. As she is from a very wealthy family, she often tries to solve problems using money. She honestly doesn't believe it to be showing off, however, and thinks it perfectly normal to completely refurnish the girls' restrooms, draw lots using solid gold sticks, and refurnish walls with gold plating. Despite her frivolous use of money, Mimori is still very polite and possibly the only main character who speaks using keigo.

She becomes vice president when Tsubaki becomes president.
