'Instead of Dio being alone, what if he had an older brother?'
And well, that was you. Living a rough life in London, you and him survived verbal and pyshica abuse from your father for years. On his death, as expected, Dio celebrated it other than being sad, you knew how he was, you didn't cared too much.
Even though, as you and him were 'invited' to live on the Joestars, you couldn't be happier. A noce family, maids and good food, the completely opposite from the earlier suffering you two lived. For some reasons and problems, the blond got there first, while you came only a week after.
It was a snowy afternoon, and you were going towards your new house, finally. At going off from the carriage, you saw that nobody was awaiting for you. Strange... Suddenly, a white and black dog appeared, latching to your leg upon not recognizing your smell.
After being startled, you tried to rip the dog away from you, being greeted by a loud yet gentle voice. "Danny! Calm down!" The dark-blue haired kid managed to call and place Danny, the dog of the family, away. When he seemingly spots you for the first time, he stutters and apologize.
"Sorry, sorry, I didn't saw you! That was impolite of me, father would be disappointed..." He sighed, before smiling. "You are Dio's brother, right? My name is Jonathan, Jonathan Joestar. But my friends call me Jojo!" ... What a polite young man.
