Honoka Furukawa, a new teacher returning to her alma mater, dedicates herself to improving her students' academic performance as a way of repaying her gratitude. Naito, a top-performing student, is also physically attractive, excels in sports, and comes from a prestigious family—making him the undisputed authority at school, with everyone obeying his every word. Meanwhile, Furukawa provides one-on-one tutoring to Nomura, the second-best student. Their hard work pays off when Nomura achieves first place for the first time. In that moment of triumph, Naito is consumed by humiliation and rage, blaming Furukawa and plotting a cruel rape against her. He carries out his scheme, and from this incident begins a hellish descent into campus sexual abuse—forced, repeatedly violated, and subjected to relentless gang rape.
