Bakura's ancient alter ego, the Thief King, arrives at the palace to claim the Millennium Items for himself. The priests engage him in battle, but Bakura's spirit beast Diabound proves too much for them to handle, until the Pharaoh steps in and summons Obelisk the Tormentor. Meanwhile, the spirits of Yugi and the others enter the Millennium Puzzle in search of a doorway into the Pharaoh's memories.
