A female cannibalistic demon or ogre, living in a secluded house in the mountains. One day a priest, Yūkei, and his retainers came by and asked if they could stay. She reluctantly agreed on the condition that they would not look inside a room. One of Yūkei's companions broke the prohibition while Kurozuka was sleeping, and discovered that the room was full of dead people. Kurozuka chased them, but Yūkei's prayers killed her.
Also a Noh play (a traditional musical drama) called "Adachigahara."
