Stone Ocean

Set near Port St. Lucie, Florida in 2011, the story follows Jotaro Kujo's estranged daughter Jolyne Cujoh, who was set up by her ex-boyfriend Romeo Jisso to serve a 15-year sentence at Green Dolphin Street Prison. Prior to her incarceration, Jolyne is stabbed by a pendant that belonged to her father and contains a fragment of the Stand-bestowing Arrow. Jolyne manifests her Stand before being visited by Jotaro, who attempts to break his daughter out while revealing that she was framed by a disciple of Dio who seeks to kill her. But Jotaro realizes too late that he was lured into a trap as he ends up in a coma when his Stand and memories are extracted as discs by a Stand named Whitesnake. Jolyne realizes the extent of her father's love for her and resolves to recover the discs from Whitesnake's user, a Catholic priest known as Enrico Pucci who met Dio in the 80s. Along the way, Jolyne gains allies in Emporio Alnino, a boy born in prison; Ermes Costello, an inmate seeking to avenge her sister. Jolyne also fights and befriends Foo Fighters, a plankton colony Pucci gave sentience to guard the stolen Stand Discs and inhabits a female prisoner's corpse. While Jolyne recovers Star Platinum, Enrico holds on to Jotaro's memories which hold knowledge of Dio's plan to establish a "perfect world" when certain conditions are met at a predestined place on the night of the new moon.

As Jolyne's group are joined by Narciso Anasui, an inmate who fell in unrequited love for Jolyne; and an amnesic named Weather Report, Pucci begins sacrificing prisoners to instill life into one of Dio's bones in the form of a green homunculus called the Green Baby that Pucci absorbs. Foo Fighters and Anasui are mortally wounded in the attempt to stop Pucci, with Foo Fighters uses the last of her strength to save Anasui's life and retrieve Jotaro's memory Disc. Jolyne and her allies escape from prison, and Jolyne sends both of Jotaro's Discs to the Speedwagon Foundation.

Weather Report retrieves his memory Disc, causing him to remember his past as Wes Bluemarine, Pucci's long lost twin brother. It is revealed that in the past, their younger sister's suicide awakened their Stand abilities and acted as the genesis of Pucci's ideology that humans would be happier having full knowledge of their fate. Weather, regaining his ability to use Heavy Weather, dies confronting Pucci and uses Whitesnake's ability to leave his Stand's Disc for his allies. Pucci reaches Cape Canaveral as Whitesnake evolves into the gravity-manipulating C-Moon, overpowering Jolyne's group as Jotaro arrives. But Pucci realizes that he can use C-Moon to replicate the new moon's gravity, allowing him to complete his plan two days early. Pucci evolves his Stand into the time-accelerating Made in Heaven, using it to rapidly advance time. Despite Anasui's self-sacrifice, Pucci kills Ermes and Jotaro, and Jolyne sacrifices herself to save Emporio.

Pucci manages to accelerate time to the end of the universe, leading to a new cycle of time and a parallel universe where all surviving humans have subconscious precognition of their lives and the Joestar bloodline no longer exists. Pucci then attempts to kill Emporio, only to inadvertently insert Weather Report's Stand Disc into the child's head. Pucci attempts to accelerate time once more, but Emporio uses Weather Report to increase the surrounding oxygen's concentration to a lethal amount. A poisoned and paralyzed Pucci pleads with Emporio to spare him long enough to make his new universe permanent, but Emporio is unmoved, and Weather Report caves in Pucci's skull.

With Pucci's premature death, the parallel universe collapses with a new universe established where Pucci no longer exists and the precognitive effects of the second universe are gone. In the new universe, with Foo Fighters not among them, Emporio encounters alternate versions of his deceased friends with Irene, Jolyne's counterpart, engaged to Anakiss, Anasui's counterpart. As Ermes's and Weather Report's counterparts join the two as hitchhikers, Emporio tearfully re-introduces himself to Irene after noticing her star-shaped birthmark as the group drive off to meet Irene's father, Jotaro's unseen counterpart.
