This Duel is loosely based on the Monster World game played by Yami Yugi and Yami Bakura in the manga.
After Joey Wheeler's victory over Rex Raptor, the gang celebrate. Some time later Bakura Ryou encounters the group and joins them in a friendly conversation. The gang talk about their favorite cards in Duel Monsters:
- For Joey Wheeler, it's Flame Swordsman
- For Tristan Taylor, it's Cyber Commander
- For Yugi Muto, it's Dark Magician
- For Téa Gardner, it's Magician of Faith
- For Bakura, it's Change of Heart
Bakura proposes a friendly duel with Yugi using his friends's cards in his deck. Before the duel commences, Bakura reveals that, like Yugi, he too has a Millennium Item, the Millennium Ring, which he uses to separate the souls of Yugi and his friends. As he tries to take the Millennium Puzzle, Yami Yugi appears and says that if he wants it, he must defeat him.
"Bakura" reveals that the real Bakura is not in his body, rather a thief and a stealer of souls. Knowing this, Yami Yugi accepts the challenge.
This duel is played as a Shadow Game, and if any of Yugi's friends were destroyed in this game, they die in the real world.
