This series shows the darker... petty... side of people and I don't know why, but I like it. Enma Ai, a seemingly harmless looking young girl, strikes a deal with people who want to get revenge on their enemies. She literally ferries those enemies to hell as they are subjected to all kinds of torture. (Those that make the deal with her are then doomed to go to hell themselves when they die as well, by the way.) What interests me is that she does it with a straight face... She feels no guilt, no remorse, for what she does. It's a job and nothing more.

Of course, Enma Ai has a depressing history and we get to know it as the series progresses. I won't spoil it in case you haven't seen it so...

I only have two Ai figures. I need to get the others as well as the Ai 1/6 doll. If only they weren't so darn expensive ;___;
