Kumiho

The ancient Chinese mythology known as Classic of Mountains and Seas provides the earliest documented record of the nine-tailed fox. According to this mythos, the nine-tailed fox originated and dwelled in a mountain known as Qingqiu(青邱), located three hundred miles east of Jishan (Mountain Ji). Both locations fall within an area characterized by hilly terrain on the map of Qin dynasty(221 BC–206 BC).

Kumiho and other versions of the nine-tailed fox myths and folklores share a similar concept. All explain fox spirits as being the result of great longevity or the accumulation of energy, said to be foxes who have lived for a thousand years, and give them the power of shapeshifting, usually appearing in the guise of a woman. However, while China's huli jing and Japan's kitsune are often depicted as either good, evil or neutral, the kumiho is almost always treated as a malignant figure who feasts on human flesh or a neutral aligned figure attempting to gain more power in its quest to become a higher being, which often involves eating or stealing souls from humans. It is unclear at which point in time Koreans began viewing the kumiho as a purely evil creature, since many ancient texts mention the benevolent kumiho assisting humans (and even make mentions of wicked humans tricking kind but naïve kumiho).

In later literature, kumiho were often depicted as bloodthirsty half-fox, half-human creatures that wandered cemeteries at night, digging human hearts out from graves. The fairy tale The Fox Sister depicts a fox spirit preying on a family for their livers. However there are also many stories in Korean literature from this era detailing the kumiho falling in love with a human and choosing not to eat them in order to be with their lover often having to do with, if a kumiho refrains from eating humans for 1000 days it too, will become human.

A prominent feature that separates the kumiho from its two counterparts (although, both Japanese Kitsune and Chinese Huli Jing having their own versions of “knowledge beads”, in the form of Kitsune’s starball and Huli Jing’s “golden elixir” neidan) is the existence of a 'yeowoo guseul' (여우구슬, literally meaning fox marble/bead) which is said to consist of knowledge. According to Korean mythology, the yeowoo guseul provides power to the kumiho and knowledge (and intelligence) to people if they can steal and swallow one. The kumiho can absorb humans' energy with it. The method of absorbing energy with the "yeowoo guseul" resembles a "deep kiss" (i.e. a kiss using a tongue). The kumiho sends the yeowoo guseul into people's mouths and then retakes it with their tongues. If that person swallows the yeowoo guseul, however, and then observes "sky, land, and people", each observation gives the observer preternatural knowledge. But the person fails to watch the "sky" in most tales, so they get a special ability but not the most important one.

Most legends state that while a gumiho was capable of changing its appearance, there is still something persistently fox-like about it (i.e. a foxy face, a set of ears, or the tell-tale nine tails) or a magical way of forcing; its countenance changes, but its nature does not. In Transformation of the Kumiho (구미호의 변신), a kumiho transforms into the identical likeness of a bride at a wedding and is only discovered when her clothes are removed. Bakh Mun-su and the Kumiho (박문수와 구미호) records an encounter that Pak Munsu has with a girl, living alone in the woods, that has a foxy appearance. In The Maiden who Discovered a Kumiho through a Chinese Poem (한시로 구미호를 알아낸 처녀), the kumiho is ultimately revealed when a hunting dog catches the scent of a fox and attacks. Although they have the ability to change forms, the true identity of a kumiho was said to be zealously guarded by the kumiho themselves. Some tales say that if a kumiho abstains from killing and eating humans for a thousand days, it can become human.

Much like changelings, werewolvesorvampires in Western lore, there are always variations on the myth depending on the liberties that each story takes with the legend. One version of the mythology, however, holds that with enough will, a kumiho could further ascend from its yogoe (spirit) state, become permanently human and lose its evil character. Explanations of how this could be achieved vary, but sometimes include aspects such as refraining from killing or tasting meat for a thousand days, or obtaining a cintamani and making sure that the Yeoiju saw the full moon at least every month during the ordeal. Unlike its two counterparts, kumiho were not thought to be capable of omnipotence or creation at will, since they were lesser creatures.
