Yugi and Yami Yugi in “Unfinished Business”

The Millennium Ring is a lot like my Puzzle. It holds an ancient spirit who depends on someone else so it can exist. And even though the spirit of the Ring is evil and controls Bakura against his will, it seems to still need Bakura in order to survive. But there's big difference between Bakura and I, Yami.

What's that?

The spirit inside my item is my friend. And you and I are always there to support each other. You were there to help me when my grandfather was in trouble, and now I'm here to help you rescue the world from evil.
