Gin Dokkaebi (Korean: "Long Goblin") #4

Who she really is and where she really came from are secret kept between the lips of skeletons. As playful as a kitten. As patient as a spider. As agile as an acrobat. As stealthy as a cat burglar. She "smells" of carnival & commando.

A Korean kunoichi, perhaps? Or is she something both more covert and more dangerous? Her apparent seamlessness using her powers belies years or decades worth of familiarity with them, including during her other training.
