Neuro Nouami isg the sadistic character from Majin Tantei Nougami Neuro.
Neuro Nougami is from Majin Tantei Nougami Neuro. The English name is Demon Detective Brain Eater Neuro. He is a demon who comes to Earth to eat mysteries which are a food source to him. There, he meets Yako Katsuragi and tortures her for fun on a daily basis. He also enjoys "nurturing" his "meals" so that he can " eat" a bigger mystery. I highly recommend this to people who love comedy and mystery and to those people who love sadistic characters. This is both a manga and an anime.
Manga: 202 chapters
Anime: 1 season, 25 episodes
