Ibuki Aoi is a newly graduated intern. She is very excited as she prepares to be the homeroom teacher of a high school class. But as soon as she arrived at class, Ibuki Aoi witnessed a male student being bullied by his friends. She intervened but it seemed the situation continued. That group of students was not gentle but very aggressive. They were the most unique group of students in the school and the class that Ibuki Aoi was in also had many teachers withdraw.
