Also known as: Dakiniten (荼吉尼天)
Dakini is a Buddhist deity who was originally an Indian goddess of agriculture. She later became a goddess of gender and lust who ate human flesh or the human heart. She was subjugated by the God of Fortune and allowed to eat the hearts of the dead.
Dakini was originally associated with the jackle in India, but since jackles are not native to Japan, she became associated with the fox instead (it's said that she turned into a white fox after being subjugated by the God of Fortune). It's thought that the worship of Dakini was then meshed into the worship of spirit foxes that originally existed in Japan. The spells of Dakini, Dakiniten-hou, are among the strongest curse-spells.
