Leona Morimoto and Saori Otokawa are new boarding students at St. Alcadia Academy. Leona Morimoto wants to rule over everyone at school and punish those who aren’t useful to her. Teachers are not immune to this. Yuuki, Ruri, and Maiko, who have no idea what is going on, become victims of the male students’ voracious sexual desires.
