In order to defeat Chili Pepper, who intends on killing Joseph Joestar, Josuke and the others head to the harbor. Jotaro believes that Chili Pepper will try to get to Joseph's boat with something that requires a battery, so he leaves Josuke and Koichi at the harbor, telling them to attack the user if he shows himself. As Josuke is dealing with his conflicting feelings towards Joseph, the very confident user of Chili Pepper shows himself.

mas parece que errar já faz
