Himuro Karen

Recognized as an influential person, which can handle high difficulty missions and has good behavior, but mentioned to be inflexible and easily annoyed.

Having joined the Public Morals Committee, she is very uptight and prude, often she respects discipline and enforces it. Strict and eager, she walks Gosha Academy like a hawk and tells other students not to do anything "indecent". In order to become a first-class Taimanin, she constantly trains, and for that reason, she is extremely strict with other students, which either disturb public morals, are idle or those who do not train properly like herself.

Karen knows that she is ticklish and easily excited sexually no matter who it is, because of that she has become prickly and distant to people to cover her weak spot. Since she avoided sexual things so far, she easily can break and follows Fuuma Kotaro in her (What if) event in TABA without much work.

She often starts fights with Onisaki Kirara because of their conflicting views of what is and isn't seen as "slutty".
