鬼女
Kijo are female demons. They resemble human women in most ways, although they are usually hideously ugly to behold. Most kijo were, in fact, once human women, but hatred, or jealously, a curse, or a wicked crime corrupted their souls their bodies into monstrous forms. Some have red or yellow eyes, blue skin, sharp horns, long claws, or other supernatural features. Usually they dress in rags and wear their hair long and unkempt, living like savages far from civilization.
Kijo refers chiefly to women who have been transformed from humans into horrible monsters – either out of intense jealousy, wicked crimes committed, or a terrible grudge that twists the soul into pure hatred. These transformed women retreat from common society into more secluded places where they continue to perpetrate their wicked deeds. They can be found living in remote mountain caves, abandoned houses, or along mountain roads where they can receive a steady supply of victims. Kijo are stronger than most humans, though their strength pales in comparison to oni. Where these demonesses excel is in magic. They accumulate powerful spells over their long lives, and are capable of bestowing hexes and curses, the ability to brew poisons and potions, and the weaving powerful illusions. Some kijo dedicate themselves to personal vengeance or some political goal, but just as often they keep to themselves and go unnoticed by humankind for centuries.
Like oni, kijo are the stuff of Japanese legends. Innumerable fairy tales, bedtime stories, kabuki plays, films, and so on have been created to entertain, to caution, and to preach morality. Women who do bad things might turn into kijo, and men who go after unscrupulous women might be heading to their deaths unknowingly.
Kijo is a very broad term that in its most general sense encompasses any female demon, just as the term oni can technically refer to any male demon. Indeed, the name kijo is formed simply by combining the two kanji for “oni” and “woman.” Though their name might suggest that kijo are the female counterparts to the male oni, there is nothing substantial to support this. While tales point to oni working either as tormentors of the damned or as menaces to human society in the living world, kijo do not seem to have any connection to Hell or the afterlife; kijo generally work solo and have their own motives. Further, kijo and oni are not commonly seen together, and little to nothing is known about how either creature reproduces (or if they even do). Rather, it is likely that kijo are entirely separate creatures from oni, other than the fact that both are commonly born from a corrupted human soul.
