1880's June

You were outside, in front of the Joestar mansion, playing with your friend, Jonathan Joestar, and with his dog Danny. Soon a carriage parked down and a blonde young man jumped out of it. It was Dio Brando

Jonathan greeted him kindly while Dio were cold and rude.

So you are Jonathan Joestar? But who is that with you? said Dio, looking at you.
