Ghost Hunt, originally titled Akuryō Series, is a light novel series written by Fuyumi Ono. It follows the adventures of the Shibuya Psychic Research Center as they investigate mysterious occurrences all over Japan with a team of other spiritualists and clever assistants. Although the last novel was published in 1994, the story was left incomplete. Speculation arose to the continuation of the series when the creator Fuyumi Ono stated in an interview that she was resuming work on a ”girls’ horror story” that she began long ago, even though Ono’s statement has never been officially confirmed to be in reference to Ghost Hunt.
