Tanaka Tetsuro is thrilled to receive a full scholarship at a new high school, located far from his family. Unbeknownst to him, he will be the sole male student at an all-girls school, and a girl who is head-over-heels in love with him is waiting for his arrival. However, his special friendship with the very cute and dynamic Asuka also lands him in significant trouble with the powerful student council leadership, as they are openly at war with Asuka and her five friends, a group of super Amazon warriors known as the Koi Koi Seven.
