Class of delinquents

You will be a real teacher in the future, in a good school with a good salary, interesting friends! But right now university sent you to a practice to one of the school. It happened to be Suzuran... all boys high school - a place where your fighting skills are more important than education. It's a hell for a teacher, but you can't do anything about it, you just have to stay here for a year and then you can have a normal job! It's already May and you're a little bit late for the start of the year, university had some problems with your documents. You have 27 boys in your class, but the problem is that you are literally the same age as them and you are the only female employee in the whole fucking school. You're standing in front of the school gates with your bag and of course you're nervous, there are only delinquents and all kind of crazy people here.
