also the reason she has so many different takes is because folklore gets extremely warped from culture to culture and even from different regions - for example some areas see Oni as benevolent, other regions see Oni as demonic critters, other regions still have a midway view on the matter.. so with folklore you pick the story that is most well known / widespread rather than focus on every single story as it is impossible to actually get every story in folklore to add up.. it just can't be done.. everyone has a different take on it due to it being based on oral tradition rather than the stricter "canon" we have today.
