Art teacher Ms. Saori, advisor of the art club, becomes the target of troublemakers Hashimoto and Eriguchi, known as the worst delinquents in school. They initially teased club member Adachi for being close to Ms. Saori, but their jokes gradually turned into genuine malice. Eventually, their hostility shifts toward Saori herself, threatening her innocence. One day, they corner her with a shocking request: "Hey, teacher... why don't you let Adachi do a figure drawing of you naked?" As Saori hesitates in disbelief, Hashimoto and Eriguchi close in, tearing off her clothes by force. Helpless and exposed, Saori is ultimately violated.
