Majin Tantei Nougami Neuro - Battle de Yo! Japan

Majin Tantei Nogami Neuro is a supernatural detective Japanese manga series written and illustrated by Yusei Matsui. The series tells the story of Neuro Nogami, a mysteries eater demon, who solved all demon world mysteries and came to the human world. To remain unnoticed amid the humans while he unravels the mysteries, Neuro uses Yako Katsuragi, a high school student, as a facade. One of the reasons that led Matsui to create a supernatural-themed manga was his inability to draw humans.
