In a world where women dominate men and chastity roles are reversed, Cleto was abandoned by his parents simply for being born male and grew up as an orphan. One day, he awakens with a unique ability: the more intimate acts he performs with women, the stronger he becomes. Through daily "training" with his dorm mother, Cleto soon gains power that rivals—and even surpasses—the strongest women. His abilities allow him admission to an elite, all-female Knightly Academy. There, to regain the honor and life denied him, Cleto must face the knights not only in the arena, but also in bed, gradually rising as the academy's unlikely hero.
