I think that works out great! I'm sure nobody would rather envision a "hideous old crone" than a cute 2hu XD. It feels just like something Zun would do when making a new character. At the same time, keeping the personalities and abilities true to original lore is a good choice. It's always interesting to learn about a new yokai, and how they behave :) Speaking of which, I'm thinking of reading Kwaidan: Stories and Studies of Strange things by Lafcadio Hearn. It seems to have many interesting tales of yokai, so I wonder if you know about it.
Also, do you think you'll ever come up with a completely original yokai? I mean adding a character that resembles existing yokai, but not directly based off of any. Might make things interesting. I think you have the imagination and knowledge to pull it off well, if you ever give that a try :)
Everybody else please vote for Oscar to rest next! :3
Anyways, can't wait to see the next chapter
I get you're busy so I understand if you don't respond to this
