New Kid? He's a Mafia Heir!

Zack Hart's gang cornered a student named Tyler and pushed him until he jumped. Ethan Rivers had transferred into Lilac High before that. He is the heir to a crime family and has never lost a fight, and after clearing out the criminal networks in northern Myanmar he wanted an ordinary student's life in the eastern city. What he found at the school was smoking, beatings and gangs. He had made friends with Tyler, who was being pushed around, and with a teacher. After Tyler's death he used his full strength on Zack's group and destroyed them. Tracing it back, he found Zack was working for someone else, a student who runs the school like a boss, and the family behind that student began sending people at him. The attacks got larger until the last one, under the library.
