- Ju-On: Black Ghost a.k.a. Ju-On: Kuroi Shoujo (呪怨 黒い少女)
After collapsing at her school, a young girl, Fukie Yokota, is rushed to the clinic. She and her mother, Kiwako, go back home after she recovered, but Fukie suddenly becomes even more unstable. The doctor tells Kiwako that a cyst is discovered in Fukie's body, but it is actually the physical remnant of Fukie's unborn twin who merged with her body during birth. Knowing that Fukie's condition is supernatural, Kiwako contacts her sister, Mariko, who is spiritually aware, to examine Fukie. But the worst of the grudge is yet to come.
