3000 Years ago marked the turning point of an Egyptian Dynasty; the Pharaoh’s spirit was sealed inside one of the ancient relics, the Millennium Puzzle, after saving the kingdom from an enemy army. Now, in the present age, the Millennium Puzzle is found by a young boy, Yugi Mutou, who unlocks the spirit of the puzzle and is possessed by the spirit of the old Pharaoh, who lost all of his memories from his old life. As a thank you to the spirit who saved him from bullies and gave him new friends, Yugi decided to help the spirit out and find a way to recover his lost memories and send him to the after life.
