Brief Bio 

In Japanese folklore, a Nukekubi (抜け首) is a type of yokai (monster) that appears as a normal woman by day, but at night, her head detaches from her body and floats around freely. This floating head can attack people, sometimes drinking their blood, before returning to the body in the morning.
