The "Ju-On" films generally revolve around a curse created in a house in Nerima, Tokyo (or Suginami in the American films) when Takeo Saeki, convinced that his wife Kayako was having an affair with another man, murdered her, their son Toshio and Toshio's pet cat in a jealous rage. According to "Ju-On", when a person dies with a deep and powerful rage, a curse is born. The curse gathers in the place where that person has died or where they were frequently at, and repeats itself there. The spirits of the deceased haunt the location, potentially killing anyone who encounters the curse by any means, such as entering a cursed house or being in contact with somebody who was already cursed. The curse's manifestation is mainly death, where the victims' bodies may or may not disappear. The following deaths may create more curses and spread them to other locations.
