Shinji Yagami is a student whose life takes a dark turn when classmate Satoshi Kojima sends him a link to a website displaying non-consensual images of female students from their school. Shinji joins Satoshi in a campaign targeting other students and teachers, involving voyeurism, bondage, and sexual violence.

As their actions escalate, Shinji witnesses Satoshi's increasingly unstable and sadistic behavior, prompting him to question his own participation. This internal conflict deepens sharply when Shinji realizes his childhood friend Miku might become their next target, forcing him to confront the morality of his choices and the potential harm to someone he cares about.
