Goth is a novel by Otsu-ichi, about two high school students fascinated by murder. It was adapted into a manga by Kendi Oiwa. Both were published in Japan by Kadokawa, and were published in English by Tokyopop in October and September 2008. The novel won the Honkaku Mystery Prize. In 2008, the novel was adapted into a live action movie directed by Gen Takahashi. Also, Fox Atomic has announced that the novel will be made into a feature film directed by J.T. Petty.
The novel contains a series of six short stories about two high school students: a boy who remains unnamed until late in the story, and a girl named Yoru Morino. Both share a similar interest in gruesome murders. While the stories were originally published in a single hardcover edition, they were later published in two bunko volumes. Tokyopop's release follows the original one volume format. The manga adaptation, by Kendi Oiwa, eliminates the Dog storyline, and combines Voice and Twins, with Morino taking Natsumi's role in the final story.
- Goth (暗黒系 Ankokukei?, Dark Type) - Morino finds a diary written by a serial killer. It describes a third victim that has yet to be discovered, so she and the narrator go to look at it. Morino then begins dressing like the third victim, and a few days later, sends a text message to the narrator, which reads only, "Help."
- Wristcut (リストカット事件 Risutokatto Jiken?, The Wristcut Incident) - Flashback to before Morino and the narrator were friends. After finding a doll with no hands in the science lab garbage can, the narrator breaks into the science teacher's house, convinced he has been the one cutting hands off people of all ages in the city. He then steals the teacher's hand collection, and plants evidence to suggest Morino was the one who stole them - because he wants Morino's hand, and the scar from when she cut her wrist.
- Dog (犬 Inu?, Dog) - The narrator investigates a series of dog kidnappings after his sister discovers a pit filled with their bodies. A young girl and her pet dog have been plotting to defend themselves against her mother's abusive boyfriend.
- Twins (記憶 Kioku?, Memories) - Morino has been having trouble sleeping, and is looking for a rope to put around her neck - the right rope will help her sleep. At the narrator's urging, she tells the story of how she and her twin sister, Yū, often pretended to be dead...until Yū accidentally hanged herself.
- Grave (土 Tsuchi?, Soil) - Saeki spends all his free time gardening, digging holes to try and control his obsession with burying people alive. He's already given in once, and killed a young neighbor boy, drowning him in his coffin. Now he's snatched a high school girl off the street - according to her ID, her name is Yoru Morino.
- Voice (声 Koe?, Voice) - Natsumi's older sister was recently found chopped to pieces in an abandoned hospital. A few weeks later, a mysterious high school boy gives Natsumi a tape - a message from her sister, recorded just before she was murdered. If she wants the rest, she will have to come to the hospital, and allow him to murder her.
