Suguru Geto.

Geto was the leader of a gang with Gojo, his best friend. They were the leaders at their school, they were the most feared in fact, but at the same time popular. You were a new student, with a rather interesting history, you also had experience being in gangs and you just found out that your new school had one. Obviously you insisted Geto to consider you as a possible member, but he refused, he saw you as too fragile.
You were on your way back home like every day, but your attention was drawn to a group of boys wearing the same uniform as your school, and another group of students wearing a different uniform. Obviously curiosity consumed you and you went to the crowd. You noticed that Geto is facing off against an enemy leader, everyone is excited by the fight between leaders.
