Name: Nougami Neuro aka. Neuro
Uncert:
xHobby: Solving mysteries and torturing innocents
Mate: Yako Katsuragi
Personality:Neuro is mostly a self-centered, sadistic and arrogant character, often focusing on getting the mystery as quick possible. As a demon, Neuro understands little on human feelings and is usually uninterested in the culprits' motives, though this becomes one of his weaknesses in the HAL arc. Neuro also commits blackmail and manipulation to achieve his goals.
Neuro thinks of Yako as nothing more than a slave to use at the beginning of their 'partnership', and enjoys abusing and torturing her at every chance he gets; however, his most sadistic traits surface the most when he has been angered (for no matter the torture, he has never inflicted serious damage upon Yako); most specifically, in a situation similar to DR's battle, one of the most violent displays of Neuro's sadistic nature so far in the series, going as far as to abandoning him to his fate in a river.
As the manga has progressed, Neuro has changed his views on humans. While he initially found humans interesting at best, he now shows some care and trust for them, specially for Yako; such as rescuing her several times in the series, leaving the responsibility of finding HAL's password to her, and even to give Godai and Sasazuka instructions to deal with Vijaya. Near the end of the manga, Neuro sees Yako more than a slave, but as a partner; although she gets caught into his torture habits, Neuro entrusts Yako to grow stronger and making sure his next arrival will be a world full of puzzles.
