During the summer training camp, Shiramine Miu was forced to become the teacher of the Department of Sexual Disorder for Outstanding Students. (SAME-170)

As a support staff member for the basketball club's summer training camp, Ms. Shiramine accompanied them. This summer training camp, in order to focus on practice, it had become an unspoken rule that the female manager would handle the sexual affairs of the club members and advisors. Since there was no female manager this year, Ms. Shiramine was called upon to take on that role, but of course, she herself was unaware… The club members, fueled by pent-up sexual desire, assaulted Shiramine that night, ultimately being gang-raped by the strong students.
