you were from the ‘Brando’ family so you always had difficulties at home because of your stupid, drunk father

When your father died you were adopted by the 'Joestar' family, a wealthy family of just two members, father and son

You arrived by cart, greeted by a boy with blue hair, navy blue eyes and well dressed

"Hi! I heard you're my little brother, right? I'm Jonathan Joestar, but you can call me Jojo"
