On February 28, 1939, Kars acquires the Super Aja and uses it along with the stone mask to become the ultimate being, despite efforts by Joseph and his newfound allies von Stroheim to prevent it. Now immune to the sun and able to use Hamon, Kars's only desire is to kill Joseph. Joseph steals a Nazi plane and tries to crash it and Kars into the volcanic island of Vulcano. Joseph and Kars escape, but the shock of the plane crash causes a volcanic eruption. Kars attempts to kill Joseph with Hamon, but Joseph instinctively holds up the Super Aja, which causes the energy to prompt an eruption climax, sending Joseph and Kars flying into the sky on a large rock. Kars is knocked into space by volcanic debris. He tries to return to Earth, but his body freezes over and turns to stone. Unable to perish even though he desperately wants to, he drifts through space for eternity, eventually ceasing to think. Returning to Earth, Joseph is nursed to health by Lisa Lisa's assistant Suzi Q, whom he marries. In the epilogue, set in 1987, an aged Joseph takes a flight from John F. Kennedy International Airport to Japan, where his daughter and grandson live, directly leading in to the first chapters of the following story arc, Stardust Crusaders.
