My friend Ozawa, who has gone missing. He was an editor of an occult magazine, and before his disappearance, he had covered ghost stories related to an area called "●●●●●". Quotes from past magazine articles, strange stories from readers, and Internet bulletin board posts - as we follow his footsteps and decipher the materials he had collected, certain connections emerge between the ghost stories that had been treated as separate incidents. This is a comic adaptation of a bizarre mockumentary horror story that was first published on the novel.
