One and a half years after the original sci‑fi psychological thriller, Akane Tsunemori keeps her post as an inspector—upholding the Sibyl System"s rulings. She is joined by fresh enforcers and junior officer Mika Shimotsuki, a young woman who follows Sibyl with blind devotion. While Akane reflects on her role and questions the validity of Sibyl"s judgments, a chilling new threat surfaces.
A shadowy individual has found a method to manipulate the Crime Coefficient—a figure derived from brain scans that lets Sibyl assess mental fitness and spot future offenders. Using this power, he kills an enforcer, leaving a cryptic message: "WC?" sprayed in blood on the wall.
Akane and Division 01 soon find themselves locked in a lethal contest with this adversary, confronting a plot that endangers not only the Sibyl System"s authority but also the very core of Akane"s beliefs in a world where morality is questioned, and the future of justice hangs in balance.
