Yugi Mutou and Aigami's Duel

Yugi Mutou and Aigami faced each other in a game of Duel Monsters in Yu-Gi-Oh! The Dark Side of Dimensions.

Prior
Aigami interfered with KaibaCorp's excavation of the Shrine of the Underworld and managed to steal two pieces of the Millennium Puzzle. He gave one of the pieces to his sister, Sera, who in turn gave it to Yugi.

Aigami displayed an interest becoming friends with Yugi. However, he sent Yugi's friends Katsuya Jonouchi and Ryo Bakura to other dimensions. Yugi learned of this and managed to reunite with Jonouchi, but continued to search for Bakura.

Seto Kaiba announced that there would be an exhibition Duel at Kaiba Land to showcase his new Duel Disk. He had a group of men abduct Aigami and bring him to Kaiba Land. Kaiba learned that Aigami did not have both pieces of the puzzle and suspected Yugi had the other one. Kaiba personally met up with Yugi and showed him that he had all of the Millennium Puzzle assembled, minus the two pieces and demanded that Yugi take part in the exhibition Duel.

When Yugi arrived at Kaiba Land, Kaiba announced that he would be Dueling Aigami and then Yugi, in order to obtain their pieces of the Millennium Puzzle. However Yugi was annoyed with what Aigami had done to his friends and intent on finding Bakura, so he insisted that he the one to Duel Aigami.
