What is it with people and Yami Yugi/Nameless Pharaoh?

I know that this is an old question, but your meaning is....?

He is sexy XD No but seriously, his character is just an amazing character with a great backstory.

I think really it has to do with the backstory of him. Also the fact that he really is a great character. I love when Yugi lets Yami out of the puzzle.
