Giorno's Gold Experience Requiem soundly defeats Diavolo and King Crimson, sending them into the Tiber. Diavolo seemingly survives and climbs up to a sewer only to be stabbed by a druggie. Diavolo then continuously experiences various gruesome deaths and his spirit is eventually broken. For their part, the team is convinced that they are victorious. Mista then tells the group to go back to the Colosseum and heal Bucciarati, unaware of his death. Seeing the spirits of his fallen comrades in the sky, Giorno sees the Arrow on the ground. The plot jumps back to the past; during lunch, Bucciarati learns that Luca has just died and must investigate it. At the same time, a florist comes and claims that his daughter has been murdered by her boyfriend, explaining that she was holding a round rock in her arms. Bucciarati accepts to also investigate the matter and asks Mista to resolve the case. As Fugo drives Bucciarati and Mista to the boyfriend's apartment, Mista suspects that he is stalked by a round rock. His suspicions worry Bruno and when Mista goes to the boyfriend's address, Bucciarati decides to go after him. When Mista uses the elevator, he spots the boyfriend and the rock reappears, which worryingly takes the shape of a dying Bucciarati.
Mista's investigation continues. Realizing that he's pitted against a Stand User, Mista quickly overpowers the sculptor, named Scolippi, and orders him to explain himself. Scolippi is revealed to a benign Stand User whose automatic Stand Rolling Stones tracks people fated to die and preemptively kills them; Bucciarati has in fact become its latest target and is following him. Rolling Stones suddenly disappears and Mista is told by Sex Pistols that Bruno is nearby. Mista begs Scolippi for a solution and the sculptor suggests that he may change Bucciarati's fate by breaking the stone. Mista manages to delay Rolling Stones and ultimately jumps down the building with the Rolling Stones to break it, surviving by landing on Fugo's car. The gang leaves, but Scolippi notices that Bucciarati's fate, as well as that of Abbacchio and Narancia were already sealed. Still impressed by Mista's loyalty, Scolippi prays that their demise may serve some purpose. Back to the present, Giorno, Mista and Trish head back to the Colosseum to "heal Bucciarati". Meeting Coco Jumbo on the way back with Polnareff's spirit lingering it the room in its shell, Giorno decides to safeguard the Arrow. Some time later, it is shown that Giorno has become a gang leader.
