Your favorite youkai/kami anime

[Renton7]

So after a 2-year break from anime (don't ask) I decided to rekindle my soul with some series that focus on youkai and similar Japanese folklore, since those tend to have self-contained episodes with often poignant stories (and one of the very first anime I saw was Hayao Miyazaki's awesome Spirited Away) and they also have a lot of varied genres from Slice of Life and comedy (Kamichu! and Nekogami Yaoyorozu) to horror and action (Ayakashi and Ayakashi Ayashi)

I guess this would've been better in the Recommendations forum dunno ^^ but this unique genre def deserves a discussion on its own.

So what're your favs and why? If it's not on the list I'll edit the poll to include it.

EDIT: added a few more

Well, the only one I have seen is xxxHolic so that is my vote

Edit: I forgot I watched a few episodes of Kamichu! but lost interest.

Tayutama
Otome Youkai Zakuro

Are two very underrated ones that should be on the list.

Well, Princess Mononoke is my all-time favourite...

Only three choices make me sad. I've seen over half of those and love most all of them.
