Yu☆Gi☆Oh! Duel Monsters

After Yuugi Mutou solves the Millennium Puzzle, his body becomes home to a mysterious spirit tied to an ancient Egyptian past it cannot remember. At the same time, the card game Duel Monsters rises rapidly in popularity, and Yuugi proves to be a gifted duelist. Competition becomes far more dangerous when Seto Kaiba targets Yuugi's grandfather in pursuit of a rare card.

With the help of his other self, Yuugi defeats Kaiba and becomes a name other duelists cannot ignore, drawing him into tournaments and rivalries aimed at both his skill and the Millennium Puzzle itself. With every duel, the nameless Pharaoh's lost history comes closer to the surface, and Yuugi and his friends discover that some games can place real memories, souls, and lives at stake.
