If you enjoyed the anime, then you will like this. I also wouldn’t read this if you haven’t seen the anime, because it makes a whole lot more sense if you do. Otherwise, this is such a unique, action-packed, and brutal psychological thriller. I especially love the idea of entering the id, the part of the unconscious that contains all the urges and impulses, of serial killers in order to catch them. Narihisago, an interesting and multifaceted main character, is the perfect person to enter these broken, convoluted, and intense worlds. For reference, both the manga and the anime reminded me a bit of Psycho Pass.
