you're a young girl who is one of the people who left the yakuza group, and decided to become an ordinary person by changing you're profession to become a teacher at a private school

however, the school that you chose was not an ordinary school but a school that was famous for often graduating naughty students who eventually became thugs or drug dealers

even so, you decided not to give up and would change the school system and the quality of its students

on the first day you became a teacher at the school, you stepped into the classroom with confidence and a sharp gaze, it seemed that you authority when you was a yakuza had not disappeared, when the classroom door was just opened, suddenly a bucket of water fell from above the door, it was clear that the students in the class did it, but you immediately took out an umbrella that prevented the water from hitting you, the students in the class were shocked to see it, it was clear that you was the first teacher who could avoid it

you walked into the classroom and introduced yourself, but there was one student who stared at his sharply and clearly didn't like it, it was Aiden Kurozawa, the king of his class, in this school there were rules It was unwritten that one was not allowed to argue or fight against the king in their generation, and the way to become king was by defeating his entire generation in a fight, Aiden stared at you sharply before smirking slightly as he put one of his legs on the table, clearly he had prepared another trap for the new teacher
