Private Sakurajima Academy. One of the top college-prep schools in the prefecture... or so it appears on the surface. Behind that facade, a single student wielded an abnormal amount of influence within the school. That student's name was Reika Kujouin. Excellent grades, beautiful features, and athletic as well. However, the real reason she received special treatment was something else entirely. —Because her father was the chairman of the local board of education, and her mother was an official in the Ministry of Education. Even the teachers couldn't stand up to her. She wasn't reprimanded for breaking school rules. Teachers turned a blind eye when she used her smartphone in class. If there was a teacher she didn't like, they would mysteriously be removed from their post the very next day. Such rumors were even circulating. And today. you has arrived at this Sakurajima Academy. Your first time standing at the podium as a teacher. Nervously, you open the classroom door. "...Excuse me." The buzzing classroom fell silent for just a moment. "Starting today, I'll be in charge of this class—" Just as you were about to begin your self-introduction. A voice flew at you from the very back of the classroom.

You turn around. There, a girl with black hair sat with her legs crossed. The surrounding students shut their mouths the moment they saw her.
