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

is a 2016 Japanese animated science fantasy film written and directed by Satoshi Kuwabara, with Kazuki Takahashi and Masahiro Hikokubo as co-writers based on the Yu-Gi-Oh! franchise by Takahashi. Produced by Studio Gallop and distributed by Toei Company, The Dark Side of Dimensions tells a new story that takes place after the events of the original Yu-Gi-Oh storyline; specifically, it is set six months after the end of the original manga, and thus features some slight contradictions to the storyline of the anime adaptation. The film stars Shunsuke Kazama as the voice of Yugi Mutou and Kenjiro Tsuda as Seto Kaiba, alongside Hiroki Takahashi, Takayuki Kondo, Maki Satō, Rica Matsumoto, Junko Takeuchi, Kento Hayashi, Kana Hanazawa and Satoshi Hino. The Dark Side of Dimensions was released in Japan on April 23, 2016, in the U.S and Canada on January 27, 2017, and in Australia on February 2, 2017. Plot As the story begins, KaibaCorp is doing research on the Millennium Puzzle. Suddenly, a mysterious cloaked man is seen at the underground shrine as one of Seto Kaiba's bodyguards tells him that he is behind schedule and to speed up his progress. Six months after the departure of the Pharaoh ("one year" in the dub version), Yugi Muto and his closest friends are preparing to graduate Domino High School and are talking about what they will do in the future. Meanwhile, Seto Kaiba has commissioned an excavation to retrieve the disassembled Millennium Puzzle from the ruins of the Millennium chamber. The item had previously housed the spirit of his longtime rival, Pharaoh Atem who is an Egyptian version of Yugi, from Egyptian times whom he hopes to "return to life" in order to settle their ancient score. The excavation is interrupted by Diva, who faces Kaiba in a game of Duel Monsters and steals two pieces of the recovered Puzzle. He keeps one fragment and gives the other to his younger sister Sera, who passes it on to Yugi Muto, as he is the only one who can reassemble the Puzzle, being the modern-day alternate version of Pharaoh Atem. Diva, under the alias "Aigami," forges a "friendship" with Yugi and the rest of his friends. He takes interest in Yugi's friend Ryo Bakura, whom he believes is responsible for the death of his father-like mentor, Shadi. Using his Quantum Cube, he transports Bakura and Joey Wheeler to another dimension. Bakura apologizes and explains that the evil spirit of the Millennium Ring had been responsible.
