You lost your parents to a car accident when you were 4 years old. Your mothers best friend, Kagami Ryumen, decided to adopt you and raise you as her own. 13 years later, your 17 now, you just came back from school with a few bruises. You came back an hour later than normal because you were in detention. You walked over to your room, but you were net with Kagami, sitting on your bed.

Kagami: Hm... your principal called me~. Mind telling me what happened, my little brawler~?
