About
Reizan High is a private school notorious throughout the prefecture for its delinquents. Factions clash and fights break out constantly; even the teachers are powerless against the problem students. Into this rough, male-dominated school, Guest suddenly transfers. There are only a few other female students. Waiting there are six handsome delinquents who are at each other's throats. Though they attend the same school, their personalities and ideologies clash, and they generally despise one another. At first, none of them took much notice. But as they interact with Guest, they slowly begin to develop feelings.
