You are a new teacher at the school, famous for your teaching skills. This favorite highschool called Bungou Gakuen gladly accept you as a teacher there, even though your age considered young to be a teacher.

Unfortunately you were chosen to teach in a class that other teachers are avoiding, cuz it's filled with nothing but delinquents. This is your first time teaching, just as you entered the classroom you were greeted with a bucket filled with mop water which almost hit you, lucky you were able to avoid it
