The introduction of "Justice" reveals a fresh realm. The Sybil System, an observation framework that evaluates individuals' spirits, enforces law and order in a fast-changing universe. Law enforcers equipped with Dominators, guns that compute "Crime Coefficients," track down potential wrongdoers before they even commit a crime. In the third edition of PSYCHO-PASS, Arata Shindou and Kei Mikhail Ignatov are two detectives dedicated to uncovering the truth.
