Yu-Gi-Oh!: The Dark Side of Dimensions

In "Yu-Gi-Oh!: The Dark Side of Dimensions," Seto Kaiba (Kenjiro Tsuda) commissions an excavation to retrieve the lost Millennium Puzzle, which once housed the spirit of the Pharaoh Atem. Six months after the Pharaoh's departure, Yugi Muto (Shunsuke Kazama) and his friends Joey Wheeler, Téa Gardner, Tristan Taylor, and Ryo Bakura prepare to graduate from Domino High School. Yugi becomes the only one who can reassemble the Puzzle, as its modern-day counterpart, a young man named Diva (Hiroki Takahashi), steals pieces of it and uses the Quantum Cube to transport Bakura and Joey to another dimension, where Bakura apologizes for the death of his mentor. Yugi, Téa, and Tristan find Diva and duel him, and Kaiba rebuilds the Millennium Puzzle, but ultimately sacrifices himself to help Yugi summon Atem, who possesses Yugi's body and defeats Diva, allowing Yugi and his friends to graduate from high school and see Téa off as she leaves for New York City.
