Angelo sneaks Aqua Necklace into the Higashikata residence in the hope of killing Josuke's mother Tomoko, but Josuke manages to catch it before it can kill her and traps it inside a bottle. When Josuke's grandfather Ryohei comes home, however, Angelo, remembering that Ryohei was the one who put him in jail, tricks him into setting Aqua Necklace free and kills him. Despite using Crazy Diamond's ability to heal Ryohei's wounds, Josuke is saddened to discover that his power can't bring back those who have already died. As Josuke and Jotaro spend the next few days thinking of a plan to stop Angelo, they become surrounded after a rain storm floods the house, allowing Aqua Necklace to move freely through puddles and mist. Angelo attempts to kill Josuke by sending Aqua Necklace through a humidifier into his mouth, but Josuke traps it in a rubber glove he had swallowed earlier. Upon finding Angelo's physical body, Josuke takes revenge for his grandfather by trapping Angelo in a rock.
