In the future, a system called Sibyl presides over the country and provides order to every facet of life. It dictates which job fields citizens should go into based on aptitude tests, and can even read each resident's mental state and predict which ones are likely to commit crimes in the future. Fresh from exams, Akane Tsunemori is beginning her career as an Inspector, a specialized police officer who works to apprehend these latent criminals and stop crimes before they happen. But not all that get caught are eliminated or jailed, some join the police force as Enforcers to provide insight into criminals’ minds, and Akane is warned not to get too close to them, as they're considered little more than hunting dogs. Though skeptical of this advice, and Sibyl's judgement, Akane is determined to work together with her Enforcers to protect the peace of her city and its inhabitants.
