Yayoi is the main heroine of the series who saved Tetsurou from getting hit by the truck that was owned by Higashikazuno Miya in front of Gokou Academy. She is the one of the members of so-called full-bloomed love, super amazon warriors group called Koi Koi 7. She had a promise that she will protect Tetsurou forever since childhood, but Tetsurou doesn&#039;t remember that he had a promise from such a cute girl. She was called &quot;Light&quot; from the girl that has the same name as her.

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. <br>
