Synopsis
Mahad unlocks his full power using the Millennium Ring, and forces Bakura to face him by trapping them both inside the tomb. Mahad's Illusion Magician faces off against Bakura's Diabound, which has grown in strength since his battle with the Pharaoh. Diabound gains the upper hand, and Bakura finishes the job by deliberately setting off the tomb's traps. To save himself, Mahad fuses his soul with his spirit beast, the Illusion Magician, transforming himself into the Dark Magician. Bakura takes the Millennium Ring and escapes, while Mahad's soul is sealed into the stone tablet meant for Diabound.
