The script was also adapted into a novel of the same name by Kurosawa himself. Plot The plot centers on ghosts invading the world of the living via the Internet. It features two parallel plotlines that eventually converge. In the first, Michi Kudo has recently moved to Tokyo and begun working at a shop that sells plants. Her co-workers include Junko Sasano, Toshio Yabe, and Taguchi, who has been missing for several days while working on a computer disk for the shop's sales. Michi goes to Taguchi's apartment and finds him distracted and aloof; while Michi is looking for the disk, she notices Taguchi’s apartment is eerily quiet. She then turns back to speak with Taguchi and finds him dead after hanging himself, his corpse visibly decaying making Michi question who was she talking to initially. Michi and her friends inspect the disk he left behind and discover it contains an image of Taguchi staring into his own computer monitor, on which Taguchi staring into his monitor can be seen - creating an endless series of images. In the other monitor on his desk, they discover a ghostly face staring out into Taguchi's room. Yabe receives a phone call and hears a distorted voice saying "help me". Upon checking his phone, he sees the same image found on Taguchi's disk. He goes to Taguchi's apartment and sees a black stain on the wall where he hanged himself, as well as a paper with "how to make a forbidden room" (akazu no heya no tsukurikata) written on it. He notices a door sealed with red tape and enters it, where he encounters a ghost. Yabe becomes depressed and tells Michi that he saw something horrible in "the forbidden room". Michi receives a call like the one Yabe got. She goes to check on Yabe and finds a black stain on the wall like the one in Taguchi's apartment. She panics when she realizes Junko has unsealed and entered a "forbidden room". Inside, she witnesses Junko being cornered by a ghost, and rescues her. Junko becomes catatonic from the encounter. She later steps toward the wall and becomes a black stain, which then dissolves and scatters as Michi tries in vain to stop it. Worried, Michi goes to check on her mother, who lives outside Tokyo.
