Transferring to St. Alkadia School was a dream come true for Takuro Hayami. He was placed in a dormitory with 4 girls, and Saori Otokawa, the dorm senior, is the sexiest of them all. A little later, Takuro discovers that sexual paradise is run by hell. In the dormitory courtyard, he encounters an overbearing blond girl. Before Takuro realizes anything, the “Amazon” whips the boy in a flash with a rubber whip, popular with S&M enthusiasts. As the car disappeared from view, Saori’s face contorted with a just anger. – I don’t care that she’s the principal’s sister! I won’t forgive her. And I’ll never give her my dear Takuro! So a women’s war of love and violence erupted in the school.
