In April 1999, Jotaro Kujo travels to a town in Japan called Morioh to find a young man named Josuke Higashikata, the secret love child of his grandfather, Joseph Joestar. Upon finding him, Jotaro is surprised to learn that Josuke also possesses a Stand.

Josuke informs Jotaro about his encounter with Angelo’s Stand. Deducing that the serial killer’s Stand is capable of entering people’s bodies, Jotaro tells Josuke over the phone to stay on high alert until he arrives at his home. Just then, Josuke sees Angelo’s Stand entering his mother's body!

Josuke and Jotaro learn that a man with a bow and arrow was responsible for awakening Angelo’s Stand ability. Realizing the town is still in danger, they decide to find the bow and arrow before it can create any more victims.

Josuke enters the Nijimura Brothers’ house to rescue Koichi, who is in critical condition after getting shot by Keicho Nijimura’s bow and arrow. But when Josuke steps into the house, he is attacked by Keicho’s Stand.

After defeating Keicho, Koichi insists they find the bow and arrow and destroy it. Josuke agrees, but when the two enter the attic where the bow and arrow are being kept, they hear an inhuman noise inside.

On his way to school, Koichi finds himself blackmailed by a man named Tamami Kobayashi, who frames him for running over a cat. A panicked Koichi starts to feel guilt for his actions, when suddenly a giant lock appears on his chest!

Josuke and Koichi get info that a student at their school, Toshikazu Hazamada may be a Stand user and decide to look into the case. Their suspicions are quickly confirmed after Hazamada’s wooden doll morphs into an exact copy of Josuke, and attacks them.

Koichi is both surprised and excited when a girl named Yukako Yamagishi says she likes him. But Koichi’s joy quickly turns into fear after Yukako begins to express her love for him in very erratic and dangerous ways.

Yukako’s dangerous obsession with reshaping Koichi into a man fit for her gets worse, prompting Koichi to hatch an escape plan. He tries to call Josuke for help using a nearby pay phone, but is stopped by Yukako, who anticipated his move.

Josuke and Okuyasu come across an Italian restaurant owned by an Italian chef named Tonio. When Okuyasu asks for the menu, Tonio explains that he decides the menu on the spot based on the customer he sees.

Josuke and his friends gather at the Port to try and reach Joseph Joestar before Chili Pepper. Speculating the enemy is hiding nearby, Jotaro orders Josuke and Koichi to stay behind and find Chili Pepper’s user while he and Okuyasu go protect Joseph.

With Akira Otoishi arrested and the bow and arrow safely recovered, peace seemingly returns to Morioh. But Josuke’s life is far from peaceful as he struggles to deal with his father, whose old age is making things difficult for them to bond.

Koichi and Hazamada visit the home of Rohan Kishibe, a popular manga artist whom they are huge fans of. Much to their joy, Rohan not only agrees to sign autographs, but also invites them to take a tour of his workspace.

Koichi is drawn back to Rohan’s house, where he sees the manga artist finishing up his next manga at an incredible speed. Rohan uses his stand Heaven’s Door on Koichi again to gain further creative inspiration from the young boy’s life experience.

Jotaro and Josuke must hunt down a rat that is believed to have become a Stand user after being shot by the bow and arrow. When the two arrive at the site, they find dozens of dead rats killed in the most bizarre fashion, confirming that their target is indeed a threat.

Koichi and Rohan discover a small alley that does not appear to be listed anywhere on the map. The two decide to go into the alley to see where it leads, but soon find themselves walking around in circles and unable to get out. Just as Rohan begins to suspect this of being the work of a Stand user, a mysterious girl appears to offer them some help.

Josuke and Okuyasu become friends with a Stand user named Shigekiyo Yangu, a.k.a. Shigechi, who can use his Stand to find and collect the money that is scattered across town. Impressed by the boy’s abilities, Josuke comes up with an idea using Shigechi’s Stand to make a little extra cash for themselves.
