I've always liked this type of animes because of the suspense and because of
how brilliant the characters are at discovering cases, but this in particular because , well, its a badass demon that eats mysteries!
Story 8/10: There's not much of an on-going story at first, since at the beggining each episode is like a mini plot, where there's a new mystery/criminal for neuro and yako to unravel.However, it get better after 5 episodes,where Neuro begins to encounter new rivals with extremendous abilities that turns the story upside down involving entire Tokyo into chaos. the plot twists will keep you in suspense and excited. Not to mention the comedy in this anime is alot different than most, with Neuro's changing personalities to a sadist yet hilarious face, the comedy here is mostly neuro making fun of his slaves/subordinates.
Art 9/10 : the art is perfect for sush a type of anime, where one person dies in almost every episode, its kind of like bitter-sweet, not detailed enough to you gross you out, and cute enough to not feel sad for the victims in each murder.actually the art in the manga is a little more obscure, so you can say that the art here is alittle toned-down to be more friendly.
Sound 10/10 : nothing bad at all, the music fits perfectly with the atmosphere of the
anime,it is quite dark and rock. i really like the opening, which really shows what Neuro is all about, while the ending theme is soft and shows how yako sees neuro.
Characters 9/10:the characters are really interesting in their personalities,its feels like each of them really adds something different to the situation. But this anime doesn't really show how the characters developed in their past, it doesn't show how Godai(slave no.2,the one with the red shirt) met neuro and Yako, which the manga does very well.
Overall:I enjoyed watching it, the plot never feels stuck and it always adds something new to entertain you,
the only problem I see is that its leaves out alot of what the manga has to offer -- the anime doesn't really show how the characters develop and they left out some of them, like Sai's assistant (she appears like for 10 sec. in one episode and then you never see her again).
Also they cut out alot of the story in the fisrt important arc, and doesn't really explain much.So if you want a more deeper version of the story, read the manga.
But Anyway, the anime really shows some action and its guaranteed to leave you satisfied if given a chance.
