(Also I will update a chapter today's no worries)
I remember finding this in thr wiki, Abe Yasunari is said to have exorcised a Nine-tailed Demon Fox.
So if this is canonically real and Yokai or demons existed.Then can't I add some interesting demons of my own.
I mean there must some magical user,who experimented too much and resulted in creation of demons.
I mean in the future,Micro-Black Hole experiment conducted by the USNA created somethting called Paranormal Parasites, otherwise known as "Vampires" or "Demons", are otherworldly beings that infest human beings and turn them into inhuman creatures known as Vampires.
I want to belive such beings existed before this,so has anyone seen the cartoon Adventures of Jackie Chan.
I found it has many interesting magical artifacts to demons, which could make the story more interesting.
