Mental State Monitor

Lore & Background

For Inspectors and Enforcers within the Public Safety Bureau, the monitor serves a dual purpose. It is not only a tool for self-regulation but also a tactical necessity during operations. When an Inspector's own stress levels rise too high due to the trauma of their work, the device warns them of potential corruption or instability. Conversely, it identifies targets whose coefficients have surged into the red zone, authorizing the use of lethal force by Dominators to maintain societal equilibrium.

In Their Own Story

The hum of the subway was usually a comfort, but today it felt like a cage. Akane adjusted her collar, feeling the cool plastic of the monitor against her neck. A soft chime echoed in her ear—her own stress level had spiked after witnessing the chaos on the platform. She took a deep breath, forcing her mind to clear, watching the digital readout in her peripheral vision drop from amber back to green. Around her, commuters walked with their heads down, unaware of the invisible numbers dancing above their heads, waiting for someone to break.

The Mental State Monitor functions by scanning neural patterns and biochemical markers to generate a real-time Criminal Coefficient score. If this score exceeds a specific threshold, the device triggers an alert, classifying the wearer as a latent criminal or an imminent threat. In combat scenarios, the monitor is inextricably linked to the Dominator weapon system. Inspectors cannot fire their weapons unless the target's coefficient confirms they are a valid threat; if the target is innocent or sane, the gun will only stun or refuse to fire entirely. This prevents collateral damage but also limits tactical flexibility. Symbolically, the monitor represents the ultimate erosion of free will in favor of collective safety. It suggests that true freedom requires the ability to sin without immediate punishment, yet this society has traded that liberty for a world where crime is mathematically impossible.

• The Sibyl System uses a 'cymatic scan' to continuously monitor the psychological traits of Japanese citizens.
• The Psycho-Pass includes a numeric Crime Coefficient index, revealing the citizen's criminality potential, and a color-coded Hue.
• When a targeted individual's Crime Coefficient index exceeds the accepted threshold of 100, they are pursued, apprehended, and either arrested or killed.
• Dominators have integrated scanners that provide the target's immediate Psycho-Pass, and the weapon can only fire when approved by the Sibyl System and triggered by its owner.
• Shogo Makishima is Criminally Asymptomatic – a person persistently assessed by the Sibyl System as having a low crime coefficient despite all actions and attitudes, thus protecting him from Dominator harm.
