is a supernatural detective Japan manga series written and illustrated by Yūsei Matsui. It is serialized in the Japanese shōnen manga magazine Weekly Shōnen Jump. The series ended its run with 202 chapters. The series has been adapted into two drama CD and an anime produced by Madhouse that first aired on October 2, 2007.

The series focuses on Neuro Nōgami, a demon who eats mysteries. Because he has already eaten every mystery in the demon world, he comes to the human world to feast on the mysteries offered by humans (who release negative energy from their planned crimes). As a demon, he does not wish to make his presence in the human world widely known. Because of this, he makes a deal with high school girl Yako Katsuragi, who has her own mystery to solve, and together they solve crimes to feed Neuro's appetite.

is a horned bird demon detective from hell who feeds off mysteries/puzzles from objects or people. When he dismantles the mystery it releases energy for him to feed on. He left hell to find a mystery to satisfy his hunger. Once in the human world, he takes on a human form and forces Yako to be his assistant to hide his identity. In public, Yako is seen as the detective while Neuro is the assistant. He treats Yako as a slave, entitling her Servant #1, and abuses her excessively; though he does keep her from being harmed in dangerous situations and respects her potential in understanding humans (nevertheless remaining as brutal to her "small" cranium as he pleases). As a person, he is highly intelligent with a sadistic and arrogant manner who only views humans as food. Neuro mentions throughout the series his desire to consume the "Ultimate Mystery", and he will do whatever it takes to achieve that goal. As a demon, he is incredibly powerful and practically invincible to any attacks. By using demonic energy, Neuro is able to use items called 777 Tools of the Demon World and 7 Weapons of the Demon Court to assist him in solving mysteries. As Neuro remains in the human world away from Shouki, his demonic energy is constantly decreasing, and his body becomes more human. Because of this, he begins to be vulnerable to human weapons. He views Sicks an enemy for endangering his food source. His voice actor is Takehito Koyasu.

is a 16-year-old high school girl. She meets Neuro when he appears and desecrates her father's shrine while promising to help solve the mystery of her father's death. This meeting quickly leads to a partnership: Yako becomes Neuro's cover, pretending to be an investigator while Neuro acts as her assistant. She has a strong understanding of human psychology, able to briefly understand Neuro and X's intentions and goals. Despite all she goes through, she is able to quickly adapt to a situation and remain calm. While as Neuro's assistant, she begins to develop her skills in detective work. She has a constant voracious appetite, thus earning the moniker of "piggish detective". Her Seiyū is Kana Ueda.
