According to some ancient documents, some occultists believe that the real nine-tailed fox should be this "nine locks on one tail" form shown in the image, which is also the most commonly seen style used by the fox spirit ancestors.
After Disas's research, it was found that fox spirits with a main tail that splits into nine strands and kitsunes with 9 tails that branch at the root are all orthodox 9-tailed foxes, but in different forms caused by different power concepts. Kitsune ancestors pay more attention to the overall power, the categories of mana are often ignored, mana storage is not differentiated, so the power storage takes the form of a trunk tail and several branches; Modern foxes pay more attention to the individual control of each attribute, and the element powers such as water, fire and wood are all classified before storage, so the tails forked at the root.
