One day, Matsuzaki Kaho, captain of the judo club, comes across a junior who seems to be in trouble after being harassed by Miyano, a vulgar senior who is the subject of constant bad rumors. Kaho manages to pull Miyano away from his persistent pestering but the incident has been recorded on video as an act of violence. Miyano, knowing that it would be bad if the violent incident were to be made public before the tournament, uses the video as an excuse to make sexual advances on Kaho. "If you don't listen to me... you understand, right?" Kaho, the captain and caring member of the club, has no choice but to succumb to Miyano's vulgar threats.
