Thanks for the replies. :) I guess I should be a little more specific:
- The reason why I am using the term "yokai" is because the main character(s) of my story is/are Japanese. Additionally, I am planning on making Japanese yokai the main focus, but for the sake of planning ahead just to be safe, I've just been brainstorming ways to incorporate other magical creatures if the possibility/need arises.
- The only thing I'm sure of, as far as using non-Japanese magical creatures, is that I'll most likely also draw from other Asian countries, such as China, Vietnam, etc.
- I have also been thinking about The Fair Folk
when it comes to European creatures, since it has been pointed out that yokai act similar to them.
- The setting for the story is in the US, and also around Japan. My reasoning is that, many Urban Fantasy
stories set in the US use English, German, and other European creatures, so the idea of using yokai in an American setting seems plausible, since there are also Japanese-Americans.
- I was also thinking of how Gargoyles
dealt with this in their show, i.e. most magical creatures were subjects of Oberon. I guess if I included other magical creatures, I'd use a system like that; the One Myth To Rule Them All
trope. Another inspiration would be the books by Rick Riordan
(Percy Jackson, Kane Chronicles, etc.).
