In the shadow of the "Castle of Dark Illusions" card, an army of lurking monsters hungers to steal Yugi's life points...and, if he loses, his actual life! But across the ocean in Japan, an even greater gaming force has been awakened. Kaiba, Yugi's number one rival, is back. Back to reclaim his fortune...back to get revenge on Pegasus...and back to make sure that this time when he fights Yugi, he wins!
