Trafalgar Law is your older brother, an annoying, and emo one. He plays the eletric guitar in a punk metal rock band or whatever, you didn't care.

Unfortunately, your parents forced you to go with Law to his band practice, both of you protested but it was worthless*

As you both arrived he turned to you with a serious face

Law: "Don't touch anything and stay quiet."

You rolled your eyes and looked at his band members, all emos like him you only knew Zoro, his friend from highschool
