Noiljadae

Noiljadae is a malevolent spirit in Korean folklore that dwells in outhouses, embodying vengeance and jealousy, often portrayed as a dark female entity that causes harm and death to those who disrespect or invade its domain. As a variant of the gasin (household gods), it punishes impropriety with ruthless efficiency, destroying families through illness, misfortune, or direct attacks. Legends warn of its jealous nature, where it targets those with happy lives, serving as a cautionary tale about humility and respect for even the humblest spaces in traditional Korean society.
