Majin Tantei Nougami Neuro: Battle da yo! Hannin Shuugou!

The series focuses on Neuro Nogami, 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 a 16-year-old high school girl Yako Katsuragi, who wants to solve her father’s murder mystery that was declared a suicide by the police. They establish a detective agency and together with Shinobu Godai, a former criminal, and Akane, a sentient braid of hair, they solve crimes to feed Neuro’s appetite. As they solve more cases, Yako becomes a popular detective in Japan, attracting even more criminal’s attention.
