SORA-637 Mind Control and Brainwashing Over Three Years: I Brainwashed a Physically Attractive Gym Teacher and Turned Her into a Broken-Doll Plaything, the Parent’s Edition by Sunao Kuui

Enthusiastic PE teacher Kuui-sensei has been going every day to the home of Takashi, a former volleyball club member who has stopped attending school, and desperately tries to persuade him from outside his room. Takashi-kun, your teacher is waiting… please come back! Kuui, drenched in sweat as he calls out, is unseen by anyone else… because Takashi-kun never existed in the first place. Everything is a hallucination seen only by Kuui-sensei. Since the incident two years ago, Takashi has been a “student” created only in Kuui’s mind. The one who created him was the fake guardian Tanaka.
