Once Josuke displays his Stand, Crazy Diamond, Jotaro shares the news of a paranormal threat in Morioh; revealed to be the result of the arrival of the Bow and Arrow, an ancient artifact inciting Stand development in suitable individuals, as delivered by one of Dio's henchmen.
The murderer Anjuro Katagiri targets Josuke with his new Stand Aqua Necklace for foiling a robbery. After Anjuro murders Josuke's grandfather Ryohei, a police officer, Josuke pledges to assume his place as Morioh's protector.
The culprits, Okuyasu and Keicho Nijimura, reveal that their father, formerly Dio's henchman, was transformed into an undying, disabled creature by Dio's cells upon his death, and that Keicho aims to create Stand users in the hope that one of them will be able to kill him. Josuke manages to prove to them that their father is at least partially human, dissuading them from their activities.
This group is then attacked by the Stand Red Hot Chili Pepper, which kills Keicho and takes the Bow and Arrow. Thus, Okuyasu joins the allies in locating this second murderer.
When defeated, Toshikazu expresses to Jotaro and Josuke the observation that, as though by fate, "Stand users are bound to meet".
Koichi is kidnapped by classmate Yukako Yamagishi, determined to make him love her whilst holding him with her new Stand Love Deluxe. Koichi's Stand develops again into Echoes Act 2 before he defeats and then rescues Yukako.
After Joseph Joestar arrives in Morioh, the allies are able to defeat Keicho's killer Akira Otoishi, user of Red Hot Chili Pepper. The Bow and Arrow are taken into Speedwagon's custody, fostering a temporary peace.
