Keepers of the Balance
These ‘creatures’ (tho they’re really magical humans) are quite rare. They are human-animal hybrids (like anime-style, not like centaurs or mermaids or whathaveyou) but they do exist. They have special abilities to talk to the animals they have parts of. They also created their own language. No one is quite sure when they showed up (or how), but the theory is that these are the descendants of the First Anima.
The First Anima were just regular humans that the manifest spirit of magical creatures would ‘choose’ and grant special powers so that they could become advocates for the magical creatures when those creatures decided to show themselves to humans (as in different species of magical creatures visited different humans). This ‘choosing’ changed the human’s spirit to look more like the magical creature, so people now just figure that that change in the spirit manifested itself in the descendents. They do not have the magical abilities the First Anima had, but they do have some typical characteristics of their animal ‘totem’ (you could call it). Only a small handful has rudimentary magical abilities.
Unlike the First Anima, whose Spirits were the only way to tell of their ‘totem,’ these Anima show their totem physically. They come in all sorts of human-animal combinations. Some /do/ just look like humans with ears and a tail (in typical, anime style), but others have more animalistic features (fur, claws, weird legs). There are even some Anima who only show /very/ slight animal features (like different eyes, or a bear Anima just being big and hairy)
