Tanaka Tetsuro is excited at getting a full scholarship at a new high school, far away from his family. What he does not know is that he will be the only boy in an all girl school, and that there is a girl head-over-heels in love with him, waiting for his arrival. But his special friendship with the very cute and dynamic Asuka also causes him to get into a lot of trouble with the powerful student council leadership, as they are at open war with Asuka and her five friends, a group of super amazon warriors called the Koi Koi Seven.
一所名校，好家庭的孩子们聚集在这里，还有一所私立百花王学校。君临以赌博为主的学校的顶峰是学生会，它主宰着弱者的生活，甚至对政治和金融部门有着绝对的影响力。然而，学生会主席罗立突然宣布解散学生会并举行大选。选举的规则是一人一票。
