She was created by the director Takashi Shimizu, representing a popular antagonist in Japanese culture, the vengeful ghost ("Onryō"). She is typically characterized by long dark hair covering her pale face, unsettling wide eyes, twisted movements with crunching neck bones, and a haunting death rattle. She first appeared in Shimizu's short movie "Katasumi" and spends the majority of the "Ju-on" series haunting a house in Nerima, Japan. She is one of the fulfillers of the Ju-on curse, which states that when someone dies in a state of intense rage, those feelings remain at the death site and kill whoever it touches.
