Koi Koi 7 Extra

Tanaka Tetsurou is excited about 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-girls 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 Yayoi also causes him to get into a lot of trouble with the powerful student council leadership, since they are at war with Asuka and her five friends, a group of super amazon warriors called the Koi Koi Seven.
