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.
