Kurozuka

The demon of Adachigahara developed fearsome magical powers. She learned to lure travelers into her shelter and invite them to spend the night, after which she would murder them in their sleep. She remained there on the moors of Adachigahara for many many years, murdering any lone travelers who passed by her cave and eating their remains. In the noh version of her story, the demon woman is eventually visited by traveling Buddhist priests, whom she plans to kill. While she is out gathering firewood, the priests find a room full of dead bodies and bones, and they recognize her as the Demon of Adachigahara. She chases after them, but they are able to hold her back with their Buddhist prayers, and drive the evil spirit from her, banishing it forever. When the demon spirit is driven from her body, she becomes an old woman and dies. The monks bury her remains and build a grave among the black mounds where she haunted.
