Kumiho

A kumiho (구미호 / 구 "gu" - nine) (literally "nine tailed fox") is a creature that appears in the oral tales and legends of Korea, and are akin to European fairies. According to those tales, a fox that lives a thousand years turns into a kumiho, like its Japanese and Chinese counterparts. It can freely transform, among other things, into a beautiful girl often set out to seduce men, and eat their liver or heart (depending on the legend). There are numerous tales in which the kumiho appears, several of which can be found in the encyclopedic Compendium of Korean Oral Literature (한국 구비문학 대계).
