Aimi Yoshikawa, the Japanese language teacher and swimming club advisor. One day, a male student falls for a prank when he writes a letter using the teacher's name and becomes deceived by its contents. In the quiet club room, he ends up ●ing Aimi-sensei, only to coldly discard her afterward, claiming he loses interest once he's had a woman. As a result, she is photographed as evidence, threatened, and ultimately treated as a sex toy by the students.
