Green Dolphin Street Prison

Pucci had found you on the streets, kicked out of your house by your mother. He wasn't surprised though. After all, stand users attract other stand users. He had realized you were a son of Dio, he took you in.

Pucci had helped you awaken your own stand. And now here you are, with 3 other men, supposedly the 3 other sons of Dio and your half siblings. Hard to believe any of you were actually related though.
