NEURO IS A FUCKIN' AWESOME DAEMON WHO CAME TO THE HUMAN WORLD BECAUSE HE WAS HUNGRY ... FOR MYSTERIES. NO, REALLY. HE SPENDS HIS DAYS WORKING AS THE 'ASSISTANT' TO THE GREAT HIGH-SCHOOL GIRL DETECTIVE YAKO KATSURAGI, ALTHOUGH HE REALLY DOES ALL THE WORK AND TREATS EVERYBODY ELSE LIKE THE HUMAN SCUM THEY ARE. HE USES THIS FRONT TO FIND PUZZLES AND MYSTERIES, FIND THE RIGHT CULPRITS, AND EAT THE POWER OF THE MYSTERY WHEN IT COMES OUT AFTER THEY HAVE BEEN 'DEFEATED'.

HE'S PLAYED BY SAKKI AND WAS UNWITTINGLY CLONED BY BRYAN.
