Joey and Duke inspect robot-monkey Tristan, hoping to find clues on how to escape. They find secret buttons on his back, one of which creates a virtual door leading them to Kaiba Land. In Kaiba Land, Kaiba boards a Blue-Eyes White Dragon train. It takes him to a volcanic battle field where Noah is waiting for him. Noah shows a sphere in the sky to Kaiba, revealing that it contains a digitized version of his brain and has kept him alive in virtual reality after he died in a car accident six years previously. Noah and Kaiba start a Duel to decide who is the worthy leader of KaibaCorp. In Kaiba Land, the rest of the gang find a handcar on the train tracks which takes them in the same direction as Kaiba's train. The brakes stop working, and they crash near where Kaiba and Noah are Dueling
