Criminal Investigation Division

Hunting the shadows within the Sibyl System's perfect society.

The Criminal Investigation Department is a specialized unit within the Public Safety Bureau of Japan, dedicated to solving complex crimes that exceed the capacity of standard precincts. Unlike regular police forces, this department operates under a unique dual-command structure designed to balance law enforcement efficiency with psychological safety protocols mandated by the Sibyl System. Members are divided into Inspectors, who hold legal authority and maintain low Crime Coefficients, and Enforcers, who are Latent Criminals permitted to serve due to their specialized skills. This arrangement allows the state to utilize dangerous individuals while keeping them under strict surveillance, creating a tense but effective dynamic for hunting the most elusive threats in society.

Lore & Background

The Criminal Investigation Department is part of the Ministry of Welfare's Public Safety Bureau. Elite officers known as Inspectors research and evaluate crime scenes, including all personnel involved, with the assistance of Enforcers. Enforcers are latent criminals charged with protecting the Inspectors, adding their expertise and carrying out Inspectors' instructions. Both are equipped with personally activated hand-held weapons called 'Dominators' whose integrated scanners provide the target's immediate Psycho-Pass.

The gun-like weapon can only fire when approved by the Sibyl System and triggered by its owner. Inspectors and Enforcers work as a team, though Inspectors have jurisdiction to fire their Dominators on Enforcers only if the Enforcer's Crime Coefficient exceeds the threshold (usually 300), indicating they pose a danger to the public or the Inspectors themselves. The series follows Unit 1 (aka Division 1) of this department, which includes Inspector Akane Tsunemori, Enforcer Shinya Kogami, Inspector Nobuchika Ginoza (later demoted to Enforcer in Season 2), Enforcer Tomomi Masaoka, Enforcer Shusei Kagari (killed at the end of Season 1), and Enforcer Yayoi Kunizuka.

Reader's Guide

The Criminal Investigation Division operates under the strict oversight of the Sibyl System, tasked with resolving high-complexity crimes that standard precincts cannot handle. Their structure relies on a unique partnership between Inspectors, who maintain pure mental states, and Enforcers, former criminals allowed to serve due to their expertise. This hierarchy ensures control while utilizing dangerous assets effectively. Ideologically, the unit strives to uphold public order without questioning the System's judgments.

However, members often face moral dilemmas when evidence contradicts Sibyl's assessments. Their methods involve profiling suspects and utilizing Dominators, which incapacitate targets based on psychological metrics rather than lethal force alone. Conflict arises internally between duty and conscience, as well as externally against organized crime that exploits the System's blind spots.
