A world-class idol who comes to Neuro&#039;s office to hire the detective team to figure out who murdered her managers/friends. She is their first customer when they opened their office. Her plan appears to be foiled when both Neuro and Yako incriminate her on television, though it can be interpreted that she is trying to clear her conscience by hiring them in the first place. Aya&#039;s voice not only affects humans, but it also influences plants and insects as seen in her prison conversation room. Her real name is Aya Aizawa. She is Yako&#039;s confidant when in need of advice and counselling, as they seem to get along very well, even after her arrest, as Aya believes that Yako has somewhat liberated her a bit from her guilt. She also has a rather strange relationship with the prison warden that constantly monitors her, having changed her for the weirder after singing to her (the warden has spikes growing out of her cheeks).

The Demon Neuro has a raging hunger for 'mysteries.' Being dissatisfied with his current regime in hell, he’s come into the mortal realm in order to satiate his ever-growing appetite. The murder case of a young girl’s father seems to be sufficiently enticing for the Demon’s needs.. But what else might happen between these two? Find out in this disturbingly good murder-mystery series. 
Included one-shot: 
Volume 23: Rikon Choutei (Divorce Conciliation)

The series focuses on Neuro Nougami, a demon who feeds on mysteries and puzzles, who 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 must not make his presence noticed by the humans as it is the law in the human world. Because of this, he makes a permanent deal with Yako Katsuragi (who has her own personal mystery she has to solve), and together they solve crimes for Neuro's appetite.
