A battle from 3,000 years ago is repeated, as Yu-Gi-Oh and Mahado - the original Dark Magician - fight Bakura and the dreaded Diabound! Can they beat the mad tomb-robber in his underground domain, protected by the darkness and the ghosts of the restless dead? But if Yu-Gi-Oh changes the past, will the present change too... or is something even stranger than time travel at work?
Meanwhile, Yugi, Anzu, Jonouchi and Honda descend into danger... to face the deadly enemy who has been right next to them all along!
