[...Well, it wasn't like the puzzle worked here, or that any other of the Millennium Items existed in this world. Yuugi bit his lip, rolling the question over in his head. Even if he told people back home, nobody would have believed him without seeing him switch out with Yami in the first place, or having prior knowledge of the items in question, so even though he hesitates a little, he nods all the same.]

I guess it's okay to tell you.

I must've been five or six...grandpa used to be an archaeologist in his heyday. I found a box with strange carvings in his room and asked him what it was, so he opened it up and showed me. A 3D puzzle, all golden and engraved similarly to the box, broken. He said nobody had ever been able to solve it, so I asked him if I could have it.

[Yuugi's lips quirked into a wry smile at the memory.]

He only gave it to me because he felt I was destined to have it. Even though it took me eight years to solve the puzzle.
