Plot
In 1999, in the town of Morioh located in S-City, M-Prefecture, a freshman named Koichi Hirose meets a man looking for Josuke Higashikata, a popular boy in high school. Josuke, who is the illegitimate child of Joseph Joestar, soon encounters the man, who introduces himself as Jotaro Kujo. Jotaro's arrival in Morioh pulls Josuke into the world of the supernatural powers known as Stands, as he becomes involved in Jotaro's search for the Stand-creating Bow and Arrow; Josuke himself is revealed to possess the Stand Crazy Diamond, which has the ability to return any object or living creature to a previous state. Josuke and Koichi eventually come across a pair of Stand-using brothers, Okuyasu and Keicho Nijimura. Keicho is revealed to be the one possessing the Bow to create Stand users, turning Koichi into one. After he and his brother are defeated, Keicho is killed by the Stand Red Hot Chili Pepper, which takes the Bow and Arrow. Okuyasu joins with Josuke's group to avenge his brother, encountering several other Stand users before they eventually find and defeat Akira Otoishi, Red Hot Chili Pepper's user, as Joseph arrives in Morioh. The Bow and Arrow are taken into Jotaro's custody and all seems to be over for the moment.Soon afterward, after Josuke spends time with Joseph, the group encounters other Stand users such as eccentric manga artist Rohan Kishibe, middle schooler Shigekiyo "Shigechi" Yangu and an aesthetician named Aya Tsuji. Koichi and Kishibe later stumble across the mysterious Ghost Street where they meet the ghosts of Reimi Sugimoto and her dog Arnold, learning that they were murdered a decade ago by a serial killer who is still lurking in Morioh. The culprit is eventually revealed to be a handsome office worker named Yoshikage Kira, who seeks to satisfy his murderous urges while living a peaceful, quiet life. Kira has acquired a Stand named Killer Queen, possessing the ability to turn anything it touches into a bomb. When his act of murdering Shigechi to conceal himself backfires, Kira uses Aya to assume the identity of a man named Kosaku Kawajiri, kills them both, and disappears. Kira's father Yoshihiro uses a second Bow and Arrow to create an army of Stand users to protect his son, including a dying cat that reincarnated as a Stand-plant hybrid named Stray Cat, which shoots bubbles of compressed air at its target.
Kosaku Kawajiri's son Hayato begins to suspect that his father has been replaced by an impostor and confronts Kira, who responds by impulsively murdering Hayato. In a panic that he will be discovered, Kira is pierced by Yoshihiro's Arrow a second time, giving Kira's Stand a new ability which revives Hayato. The following morning, Hayato is approached by Rohan, who is investigating whether Kira has assumed Kosaku Kawajiri's identity. After using his Stand to read Hayato's memories, Rohan is blown up by a miniature version of Killer Queen, which had been implanted into Hayato; Hayato suddenly finds himself back in bed on the same morning, one hour earlier. Kira explains that he has infused Hayato with his new ability Bites the Dust, which kills anyone who asks Hayato for Kira's identity and rewinds time by one hour afterward, with the victim's fate cemented regardless of Hayato's attempts to prevent it. The next loop ends with Josuke, Jotaro, Okuyasu, and Koichi all exploding as well; Hayato wakes up once again, and must get Kira to turn off Bites the Dust within one hour in order to prevent the others' deaths from becoming permanent. Hayato takes advantage of his knowledge of the time loop to wake Josuke up early and arrange for him to overhear Kira blowing his cover, forcing Kira to cancel Bites the Dust just in time to save the group.
Josuke, with help from Hayato and Okuyasu, engages Kira and Stray Cat in a pitched battle; Yoshihiro is blown up after Josuke tricks Kira into targeting him. As Jotaro, Koichi, and Rohan arrive on the scene, Kira attempts to use a paramedic to activate Bites the Dust and rewind time once more, but is stopped by Koichi and Jotaro. Kira is accidentally run over by an arriving ambulance and dies, with Reimi subsequently forcing her killer's soul into being dragged into the underworld. Her mission accomplished, Reimi gives the group her final farewells and moves on to the afterlife. The next day, Jotaro and Joseph return home as the summer of 1999 draws to a close for the residents of Morioh.
