>>31160347> Why ninetales isn't fairyNine-taled foxes have a huge history in folklore. They are most commonly identified with fire as they are often messengers of harvest gods and affiliated with sunlight because of it. At night they conjure mystic fire to light their way. Sometimes these fires are supposedly the fox's spirit in a ball form.
I think the Alola ninetales is more a reference to the docile and fragile foxwife: a kitsune that decides to marry a human. These gentle beings use magic to help their new spouse. One trespass against their taboos can make them flee or even die, however! Fox husbands also happen but foxwives are most common (Ninetales/vulpix in both types is mostly female).
