Shiramine is a teacher who is to accompany the basketball club to the summer training camp as a supporter. During this summer training camp, it was an unspoken rule for female managers to take care of the club members and advisors in order to concentrate on training. Since there is no female manager this year, Shiramine was called to fulfill her role, but of course she had no idea about that... Shiramine is forced to be a part of the club members who have a slaughtering sexual desire at night, and is surrounded by strong students.
