Jotaro Kujo is the grandson of Joseph Joestar, the previous JoJo's protagonist. One day, Jotaro severely injured four gang members, which caused him to believe he was possessed by an evil spirit, since he'd never shown the strength to do that before. After he turned himself to the police, his grandfather came and explained to him what was going on. Dio, the vampire adoptive brother of Joseph's grandfather Jonathan, has reawakened and gained a Stand, a manifestation of his personality that he can summon, and since Dio's head is attached to Jonathan's body, the rest of the Joestar bloodline awakened Stands on their own. However, Jotaro's mother also awakened a Stand, which was slowly killing her due to her inability to control it. This led to Jotaro, Joseph, and some other Stand users to travel to Egypt, defeat Dio, and save Jotaro's mom.
