About them:
A spirit from 3000 years ago who locked himself away into the pendent that he keeps around his neck called the Millennium Puzzle. Enjoys playing games and at one point in life punishing people in rather terrible ways (One case is simply setting someone on fire. Thought hat guy was a killer so it's not all bad.) He got better at that though and doesn't do it any more. Instead he just wants to look out for his friends and currently just wants to go home.

Is also confused as to how they managed to separate him from his partner; Yugi... because he thinks that shouldn't happen.
What you're looking for:
I am never picky about what to look for. I am always fine with anything. Though trying to give him a reason to want to stay is always a good first start.
What you'd rather avoid: Considering what he was like the beginning of his canon...There is nothing to avoid.

Shipping: It could be possible, but it would take a long time.

I am usually easier to get on plurk as I don't use much else.
