Yugi's classmate Bakura, possessed by his Millennium Ring's dark powers, traps Yugi and his friends in a Shadow Game where they become the cards themselves!

Trapped in the labyrinth cave, Yugi and friends find an alternate exit, but the door is guarded by Pegasus’s Labyrinth Brothers. Yugi and Jonouchi will no longer be battling solo; they band together in a team battle against the Labyrinth Brothers! The battle for all the Star Chips and entrance to Pegasus’s castle is on the line!

Yugi begins spinning a strategy to put Blue-Eyes Ultimate Dragon to rest, but he must decide whether to claim victory or spare Kaiba his life. Yugi’s heart is split in two!

Pegasus punishes Yugi using the same Toon Deck and mind-reading abilities he used on Kaiba. As Pegasus turns Yugi’s monsters against him, Yugi loses the will to battle. Will Pegasus capture Yugi’s soul into a card, just like Kaiba?

Dartz plants the souls of our captured heroes into Mirror Knights to use them as puppets to fight the Pharaoh and Kaiba! How can the Pharaoh duel when attacking Dartz may force him to attack Yugi? Does he dare risk eliminating his best friend forever? Our heroes better beware, for this is the least of Dartz’s malevolent manipulations as his dark designs come to light!
