She's from Fox Spirit Matchmaker, a Chinese cartoon.
She's an alien who initially took the form of a fox but later takes on human form.
Lore explains that the more power she gains, the more tails she'll grow, and once they've completed that cycle, they can take on human form.
They feed on emotions like a parasite and can learn the abilities of their hosts, not to mention that the hosts themselves are corrupted by them.
There's not just one, but several, and these creatures are nicknamed dark foxes.
She appears in human form starting from the Jin Chen Xi arc (Season 9-11)
