Through hard work and academic achievement, Sugisaki Ken was able to join the esteemed Hekiyou Private Academy's Student Council. As a council member, he boldly pursued his plan to form his own harem with four other female members: Sakurano Kurimu, the youthful president; Akaba Chizuru, the cool and kind-hearted yet sadistic secretary; Shiina Minatsu, the tomboyish and hot-blooded vice-president; and Shiina Mafuyu, the ephemerally beautiful yet complicated treasurer. Since then, every day has been filled with excitement. However, as graduation approaches, it seems their carefree days may come to an end.
