Stardust Crusaders - Chapter 1 
In the year 1987, 17-year-old delinquent Jotaro Kujo, grandson of Joseph Joestar, and son of Holy Kujo, is temporarily detained after beating up three armed men and a trained boxer. As Jotaro is now free to leave, Holy asks her son to come home, but despite her insistence, he refuses to leave his cell, claiming that he is possessed by an evil spirit. His prison mates confirm this bizarre claim, desperate to get out of the shared cell, seemingly fearing this 'evil demon'.
The guards notice Jotaro somehow drinking a can of beer and reading Weekly Shonen Jump while listening to a radio within his cell, freaking out at how he managed to retrieve all those items. Jotaro explains that the evil spirit brings things to him.
To prove he isn't lying, he demonstrates by taking one of the prison guards' gun – summoning what looks to be another person's arm to do so – and shoots himself in the head. However, the bullet is stopped by the mysterious floating arm that only he and his mother can see, holding it in midair. Jotaro reveals that the evil spirit bounded itself to him only recently. In response, Holy mentions that Jotaro's grandfather, Joseph Joestar, also possesses mysterious powers.
The scene then shifts to near the Canary Islands in 1983, four years earlier, off the coast of Africa. A group of treasure hunters uncover a heavy, 100-year-old coffin from the water, believing it to be a large treasure chest.
