Overview:

Three female idols appear on a television show to investigate an exorcism. An exorcist with psychic powers named Unsui claims that the show’s subjects, the Kaneda family, are cursed by a demon that’s too powerful for him to banish on his own, so he calls in a fellow exorcist to help. Soon, a reckless ghost hunter enters the fray as the three idols witness a series of terrifying events.
