In April 1999, roughly ten years after his battle against the evil vampire Dio, Jotaro Kujo travels to the town of Morioh to look for a boy named Josuke Higashikata. After first running into a timid boy named Koichi Hirose, Jotaro comes across Josuke as he fights with some upperclassmen who injured a turtle and insulted his hairstyle, discovering that he possesses a Stand that has the power to heal wounds. Jotaro then introduces himself, revealing to Josuke that he is the illegitimate son of his grandfather, Joseph Joestar, thus technically making him Jotaro's uncle. When Jotaro inadvertently insults his hairstyle, Josuke brings out his Stand Crazy Diamond[q] against Jotaro, who narrowly avoids serious injury thanks to his Star Platinum's ability to temporarily stop time. Afterwards, Jotaro warns Josuke about a dangerous Stand user and serial killer named Anjuro "Angelo" Katagiri who is hiding out in town. The next day, as Josuke encounters a convenience store robbery, he steps in after his hair is insulted again and uses Crazy Diamond to save the store clerk and implant the robber's knife inside the man's own body. Just then, Josuke discovers that the robber was being possessed by Angelo's Stand, Aqua Necklace, who threatens to kill Jotaro and his family.
