Neuro: Supernatural Detective - S01

Yako Katsuragi is a famous high school detective who has solved many cases despite her young age. It seems there is no case she cannot solve, and no culprit who escapes justice. But inside her detective agency is the secret to her success: the cases are actually solved by her assistant, Neuro Nougami. Calling Neuro an ordinary man would be wrong. He is actually a demon who came to the human world looking for the ultimate mystery, having already solved every mystery in the demon world. Using Yako as his front, he feeds on the negative energy humans release when they commit crimes. He promises to help Yako solve the mystery of her father's death. To do that, he must avoid drawing too much attention to himself, which is why Yako plays the role of the detective. As Yako desperately searches for the truth about her father's death, the unlikely pair keeps solving case after case to satisfy Neuro's endless appetite.
