Young girls from poor families can rarely count on a successful marriage. After all, their provincial suitors usually have neither influence nor sufficient funds. That's why attractive girls are so attracted to Edo, a city where aristocratic clans and rich nobles live.

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.
