Yo-Yo Ma Is Coming! (ヨーヨーマッが来る！ Yō Yō Ma ga Kuru!) is the fifteenth story arc in Stone Ocean.
Having opted to escape the punishment ward from the eastern exit and reach the nearby swamp, Jolyne, Anasui and F.F. take a motorboat to cross it. However the embryo which was in their possession is swallowed by the automatic Stand Yo-Yo Ma. Unable to hurt him, F.F. stays behind to kill D an G while Jolyne and Anasui take Yo-Yo Ma on board.
Jolyne and Anasui are pursued by the prison guards and have to hide in the swamp. Jolyne realizes that she is slowly being melted by Yo-Yo Ma but she cannot communicate properly and is incapacitated. At the same time F.F. discovers that Enrico Pucci is the mastermind behind the attacks.
