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 is not gentle at all but very aggressive. They are the most unique group of students in the school and the class that Ibuki Aoi is in charge of also has many teachers withdrawing.
