Through a chance encounter, Murakoshi—a student despised and shunned by everyone at his school—comes into possession of a "hypnosis-inducing device." He uses it to bend the entire student body to his will. Then, a new student named Midori Yano arrives and, to his utter disbelief, confesses her feelings to him. Though skeptical, Murakoshi finds his heart racing. Even as he spends his days hypnotizing the school idol, Sanae Kurasawa, and having his way with her in the hallways, he finds his gaze drifting toward Midori, who has joined the track team for a trial session. Noticing him, Midori waves back with a bright, cheerful smile. Meanwhile, Mayumi Takasaki—who took over as acting principal after the previous one was ousted—is forced to serve him in every way imaginable, from front to back and with her mouth. As Mayumi’s body reacts despite her resistance, she points out to Murakoshi that he hasn’t used hypnosis on Midori. It forces him to realize that, somewhere along the way, he has truly fallen in love with her. Finally, he finds himself alone with Midori... When she asks, "Could you turn off the lights?" Murakoshi complies without a second thought. He had hoped to continue loving her just like this—but then...!
