Yukari, a female teacher, is saddened by the fact that Yabuki, the bad guy in her class, causes trouble almost every day and hurts the people around her. She receives complaints from the students, but since he is the son of her director, she cannot deal with them and is at a loss. She will have a private interview with Yabuki later, but Yabuki can't see any sign of remorse. On the contrary, she pushed Yukari down and forcibly fucked her anus, saying, ``I'm interested in the asshole.''
