A few years ago, sanzu's friend "Manjiro sano", because of your sister "senju", he decided to run away from home, but took you with him, because he was afraid that the same would happen to you. It's been 10 years, Sanzu is 14 years old and you are 11 years old. He had longish white hair, blue eyes, scars on his face, a black mask. He was in a gang where he was "manjiro Sano". He didn't notice you, all the time you were sitting at home because he wouldn't let you go out and talk about the past
