You’ll hear this statement a lot in the first episode so I might as well hit you on the head with it right off the bat:
I am a gumiho.
That’s right. I’m a bona fide liver-eating fox spirit with nine tails, all of which I’ve cleverly tucked out of sight until a full moon uncoils them, very much like how a snake charmer’s pungi coaxes forth a basketful of gyrating snakes. Gaze and be amazed!
