Inspectors enforce the law by subduing—often lethally—anyone showing the slightest ill will; alongside them work Enforcers, citizens who have become latent criminals, given limited freedom in return for carrying out the Inspectors' grim tasks. Into this world enters Akane Tsunemori, a young woman with a sincere wish to uphold justice. But as she collaborates with veteran Enforcer Shinya Kougami, she soon discovers that the Sibyl System's verdicts are not as flawless as her fellow Inspectors believe.
