Aside from a great opening and ending theme, really this anime left me wanting more. I will warn, there are some rather intense scenes that aren't for everyone, but considering at it's core it's good. It's difficult to describe, but the more I watched, the more intrigued I became, wanting to know more about the world, about the deities and demons that inhabit it. It's interesting to see supernatural deities more involved in the human world, fictional or not, and it does a good job of obscuring the lines between good and evil. If you can get past some heavy themes, I do recommendit.
