Yu-Gi-Oh!, known in Japan as Yu-Gi-Oh! Duel Monsters and alternatively subtitled Rulers of the Duel in the United States and Canada, is a Japanese anime series animated by Studio Gallop based on the Yu-Gi-Oh! manga series written by Kazuki Takahashi. It is the second anime adaptation of the manga following the 1998 anime television series produced by Toei Animation. The series revolves around a young high school boy named Yugi Muto who battles opponents in the Duel Monsters card game. The series begins from chapter 60 in volume 7 before loosely adapting the remaining chapters of the original manga by making story changes that conflict with the events of the manga canon.
