>>8129920Actually all nature spirits, youkai, monsters and whatever are classified as fairy. It's just the traditional name for beings along that line given by Northern Germanics. I don't even know if they have an actual name, I think in Greek mythology they have, but later on "fairy" became a synonym for the little insect-like thingies and those looking like children with all sorts of nature wings and plant features. You see already there a connection that almost any creature of folk lore has an animal or plant feature integrated in them, but this again is another topic to theorize.
These "fairies" were in the old days monster feared by childen up to young adults, the little ones for taking anyone away to their realm who did hurt the local forest area somehow and the more human children like ones even if they would look like cute lolis, they are considered to be fucking demons, they kill and eat humans on spot after eye contact just like in tales of generic youkai from Japan.
Over the ages everything has been cutified and modernized like all the other known creatures of folk lore, once feared creatures are now loved by children and a symbol of innocence and purity, which actually can be said to be true if they really were created by the mind of Earth to protect nature.
