→Plot Summary
While [[Tristan Taylor|Tristan]] and [[Téa Gardner|Tea]] are still warding off the Big 5's thugs, the flying machine has just been repaired, and [[Yugi Muto|Yugi]], [[Joey Wheeler|Joey]], and [[Mai Valentine|Mai]] are set for the "[[Castle of Dark Illusions]]". But when they approach the castle, a herd of monsters is waiting for them, and they defeat as many as possible while penetrating the barrier surrounding the castle. In the process, Adena's aide ([[Earu]]) takes a hit for the heroes, and his death angers Yugi so much as to call Yami into the fight from this point on. Although the flying machine is destroyed soon after, the heroes ride "[[Winged Dragon, Guardian of the Fortress 1|Winged Dragon]]" and make it to the castle, where they must battle even more monsters. Meanwhile, the captured [[Mokuba Kaiba|Mokuba]] is brought to join [[Seto Kaiba|Kaiba]]. However, Mokuba still has Kaiba's cards, and he uses "[[Swordstalker]]" to free Kaiba. Mokuba then hands Kaiba back his Deck and he then uses it to wipe out the monsters guarding him. Then, he and Mokuba rejoin Yami, Joey and Mai.

Suddenly, the Big 5's voices are heard. Having monitored the progress of the heroes, they have decided to join the battle personally. By overriding the game, they brush away the castle setting. Then, they skip any need for a sacrifice ritual and summon the "[[Five-Headed Dragon|Mythic Dragon]]" immediately, speaking through the monster. For good measure, they set a condition that only Dragon-type monsters are allowed to attack. The heroes' initial attacks are useless, and the Big 5 take advantage of Mokuba's lack of a monster to target him. Joey orders [[Red-Eyes B. Dragon|Red-Eyes Black Dragon ]] to take the attack instead, and when his Life Points reach zero, he vanishes. Mai also falls by intercepting the attention of the Big 5 while Yami tries to convince Kaiba that he has a plan but needs Kaiba's help for it. But the next attack targets Kaiba, and Mokuba pushes him out of the way, collapsing fading from his brother's arms. This convinces Kaiba to cooperate, and Yami summons "[[Dragon Master Knight]]" to defeat the dragon. In a rush, he and Kaiba reappear at Adena's palace, and she honors their bravery by showing that she is in fact the "Mystical Elf". With her magic, she brings back Key Mace and their friends, and the heroes return to the real world safe and sound.
