(Buddhist) The Jikininki demon originates from Japanese Buddhist mythology. Jikininki are the spirits of selfish, greedy, and ungodly people who have died and are then cursed to eat the flesh of rotten corpses. They take the valuables from the deceased to bribe local law enforcement. These demons hate what they are and are stuck in a constant state of self-disgust and self-loathing. These demons are rare and unlike other gaki or rakshasa ("hungry ghosts").
Jikininki are said to be so vile in appearance that those who see it freeze in place, paralyzed with fear. Some accounts state that some may appear as humans and may even lead ordinary everyday human lives by day.
