Umm... "interesting" isn't really the word I'd use for it.
Isn't Sugimori Japanese anyway?
But yeah, those are scary.
Seems to be mimicking traditional depictions of youkai, Japanese demons. You know, literal Pocket "Monsters."
Really interesting stuff.
Oni are more afterlife-related. Youkai implies ghosts, witches, kappa, and all the other 'spooky' Japanese monsters.Ah! That's the word I was looking for. I thought it was Oni but Yokai is more widely used to describe monsters in general rather than just demons and ogres. You're right.
