Whilst following Wamuu's trail of blood, Joseph and Lisa Lisa encounter another vampire named Wired Beck, but Lisa Lisa manages to defeat him easily using her Hamon-empowered scarf. As they press on, Joseph states he will not take the antidote he received until he has beaten Wamuu as a promise to Caesar. They soon arrive before Wamuu, where Kars is also waiting for them, along with a hundred vampire minions. Lisa Lisa manages to hold off their attack with a bluff saying that if both she and JoJo are killed, a time bomb will destroy the Red Stone of Aja. Thus, she proposes that Joseph fights against Wamuu whilst she fights against Kars with the Red Stone on the line. Wamuu and Kars arrange a place for the battle at midnight, keeping Lisa Lisa as insurance to make sure Joseph brings the Red Stone. Whilst retrieving the Red Stone, Joseph finds a picture of his grandmother Erina from fifty years ago, becoming curious as to why Lisa Lisa would have it. Upon meeting at the arena, Lisa Lisa reveals that she was the baby that Erina rescued from the ship that fateful day 50 years ago, further explaining how she was raised by Straizo, who was the one who taught her about the Hamon and gave her the Red Stone. As Joseph and Wamuu's battle is revealed to be a chariot race using vampire horses, easily controlled by JoJo through reigns that conduct the Hamon, Joseph puts on Caesar's bandana and prepares to battle.
