Rookie inspectors Arata Shindou and Kei Mikhail Ignatov join the Public Safety Bureau's Criminal Investigation Division, enforcing the judgments of the Sibyl System, the AI network that scores every citizen's Psycho-Pass and decides who counts as a threat before they act. Rising anti-immigrant sentiment and political maneuvering around Sibyl's authority put the two inspectors in the middle of cases that test whether the system they serve is as impartial as it claims. This manga adapts the Psycho-Pass 3 anime.
