Neuro: Supernatural Detective

Neuro: Supernatural Detective, known in Japan as Majin Tantei Nōgami Neuro (魔人探偵 脳噛ネウロ; lit. "Demon Detective Neuro Nōgami"), is a Japanese manga series written and illustrated by Yusei Matsui. The series follows Neuro Nōgami, a demon who depends on mysteries for sustenance. Having consumed all the mysteries in the demon world, Neuro travels to the human world in search of more. There, Neuro recruits high school student Yako Katsuragi as a facade for a detective agency. The supernatural-themed manga was created because Matsui considered himself unable to draw humans.

The manga was originally serialized in Shueisha's Weekly Shōnen Jump from February 2005 to April 2009, with its chapters collected in 23 tankōbon (bound volumes). A 25-episode anime television series directed by Hiroshi Kōjina and animated by Madhouse was originally broadcast on Nippon Television from October 2007 to March 2008. In 2011, the anime series was licensed by Viz Media and uploaded to the company's website. Neuro: Supernatural Detective has spawned a light novel, two audio albums, two video games, and other merchandise.

Neuro: Supernatural Detective's manga has been popular in Japan, frequently ranking in the weekly top ten list of best-selling manga. It has sold over four million volumes in Japan. The anime, however, has been criticized by fans because it deviates from Matsui's work, and received a low viewership. Critics of anime and manga often compared it to Case Closed, noting supernatural themes as the only difference between them.
