Psycho-Pass: Inspector Shinya Kogami Volume 1 (Paperback)

Working within the city-regulating Sybil System, Inspectors must fight crime in a future where a single number measures your criminal tendencies and determines if you are useful to society. An artificial organ with a numbered brand is the key piece of evidence that leads Section 3 to a network of organ smuggling. They must set up a complicated trap in order to catch the culprit - however, the real perpetrator may not be who they think it is.
