Yu-Gi-Oh!: Duelist, Volume 9: Dungeon Dice Monsters (Yu-Gi-Oh!: Duelist #75-83)

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 of the picture forever. First a sinister clown-masked figure steals Yugi's Millennium Puzzle! Then Ryuji Otogi, the teenage heir to the store, challenges Yugi to a collectible dice game of dragons and monsters. But without the Millennium Puzzle, Yugi can't call on Yu-Gi-Oh. Can he win without his "other self" to help him out?
