I know there's like twelve different kinds of youkai and then there are the...seven...ish? Yoguai in China but other than that I'm pretty much stumped.

I dunno much, beside the usual black dogs of omen. Plus the tiangou.

Yeah, I'm familiar with the Tiangou and the Tengu, which are extremely similar. I just don't know many other kinds. Because you've got the Inugami, the Yama-inu, the two that start with bake whose names escape

me at the moment. Then the other ones from Chinese myths, but I'm not familiar with much else.
