Changes

Dark Yugi explains the rules of the game, [[Labyrinth Treasure Hunt]]. Somewhere within the soul is his true room. If Shadi can find, he'll find what he's looking for. Shadi smirks that he has one power that he didn't tell Dark Yugi about; When he enters someone's soul room, he can redecorate it to control the person or even destroy their personality. With that, he accepts the challenge.

Dark Yugi laughs that the game is more dangerous than Shadi knows. The rest of the room appears and Shadi finds himself in a maze of stairways and doors. Yugi shouts "Game start!" and Shadi looks around bewildered. Dark Yugi asks what's wrong, the game won't start until Shadi takes the first step. Shadi looks ahead and sees countless doors, only one of which leads to the true room. In order to find it, he starts opening the doors one by one.

After opening the first door, a stone pillar is dropped from above. Shadi leaps away and falls back to dodge it. As Shadi gets back up, Dark Yugi asks if he gives up and remarks that at this rate, he might get himself into trouble. Dark Yugi slips through the wall, telling Shadi that he'll be waiting in the room.

Shadi tries a few more doors. He comments that this soul is tightly closed against strangers. Although it seeks to confuse him, he refuses to give up, as he must know the secret of the [[Millennium Puzzle]].

===Museum===

Back in the museum, Shadi is now on his knees, catching his breath in front of the [[Yugi Mutou (manga)|regular Yugi]]. Shadi thinks to himself that he entered Yugi's soul to test him, but instead was tested himself. Yugi asks Shadi if he's okay. He tells him that he closed his eyes and stopped moving. Shadi says that he is alright and that Yugi is a strange boy. He takes the Millennium Puzzle out from inside his robes and hands it to Yugi, saying he believes that it's his. Yugi celebrates and thanks Shadi. Shadi smiles that Yugi doesn't need to thank him, as he is already in Yugi's debt. Yugi is confused by this and wonders if he's done anything for Shadi. Shadi explains that it was the [[Dark Yugi (manga)|other Yugi]], but Yugi laughs at the idea of there being another him. Shadi realizes that Yugi is unaware of his other self, but when they join the true power of the Millennium Puzzle shall be awakened. He asks Yugi his name. Yugi replies that it's Yugi. Shadi then tells him that he must discover his other self and solve the riddle of the power of the Millennium Puzzle, as it is the destiny of the person who solves it.
