クリムゾン学園

Crimson Academy.
250 female, 33 male students attending.
This school is absolutely ruled by "girl power".
In fact, most of that power was held by three members of the student council...

Azusa Tokuda, the boy-hating charismatic amateur model.
Marika Kai, a mixed martial artist who prefers coed fights.
Nei Honami, council president and queen of the academy.

Should any boy cross these girls, that's the end of him.
This was their world. Girls world.

And their lasers of power are triangulated on the new guy, Rio Kaminuma.
