Takuro Hayami has enrolled at St. Arcadia School, which is controlled by the powerful Morimoto family. Reina, the eldest of the Morimoto sisters, is the school principal, and Leona, her younger sister, manages the social life of the students by heading the club.

The action takes place in a world created by Courreges Studios. The protagonist is Futaba, a second-year student. She is different from her classmates in that she has genitals of both sexes. Because of this, she faces difficulties: her sex drive overwhelms her and she is forced to masturbate in different places in the school.
