Yobi

여우비

Yobi is a five-tailed fox who, after spending a hundred years in the forest with some aliens whose spaceship had crashed, develops an interest in humans, particularly in a boy named Hwang. She can transform into a human, among other abilities, and spends time with Hwang, but because common folklore claims that nine-tailed foxes (in her case, five) steal the souls of young men, her true identity cannot be revealed.
