There's a new game shop in town, peddling a hot new game, and things look bad for Grandpa Mutou's family business! But the Black Crown game store is more than a business competitor...its owners want to put Yugi and his grandfather out the picture forever. First a sinister clown-masked figure steals Yugi's Millennium Puzzle! Then Ryuji Otogi, the teenager heir to the store, challenges Yugi to a collectible dice game of dragons and monsters. But without the Millennium Puzzle, Yugi can't call Yu-Gi-Oh. Can he win without his "other self" to help him out?
