Yugi Mutou and Dark Bakura's Duel (manga)

Yugi Mutou and Dark Bakura faced each other in a Shadow Game of Duel Monsters, during the Shadow RPG.

Prior
After Mr. Clown broke apart the Millennium Puzzle, Dark Bakura used his "Parasite Mind" ability to seal a part of his soul within a piece. He then returned the piece to Yugi, who reassembled the puzzle. This manifested into an extended persona of Dark Bakura, living within the puzzle, serving as a spy. This portion of Dark Bakura's spirit followed Yugi and his friends into the World of Memories, during the Mind's Labyrinth search.

Yugi, Katsuya Jonouchi, Hiroto Honda and Anzu Mazaki undertook the task to learn Dark Yugi's real life, during the Shadow RPG. They ventured to his tomb, in the hopes of finding it. The portion of Dark Bakura that had followed them, waited for them inside the tomb. Yugi foresaw their meeting after finding a "Destiny Board" Duel Monsters card inside the tomb.

Dark Bakura challenged Yugi and his friends to a game of Duel Monsters. Yugi accepted, understading it would be a Shadow Game, in which the loser would die. Both players' Decks became composed of 40 cards that they imagined. Yugi constructed a Deck that not even Dark Yugi knew about and saw this Duel as a test for himself.
