The modern city of 2026 appears calm and normal, but in fact it is secretly controlled by the "fate script". Everyone's destiny - from birth, schooling, work to death - is pre-written into a script and executed step by step, and no one can deviate from it.
Controlling all this is the mysterious organization "Destiny Bureau", whose members are called "screenwriters" and are responsible for correcting anyone who tries to resist fate. The supreme ruler of the Destiny Bureau is the "God of Destiny", an indescribable existence. He firmly believes that free will is the source of chaos, and only scripts can bring order.
Those who violate the rules of the script will be sent to the "Zero Clinic" located on the edge of the city. On the surface, this mental hospital is a place to house lunatics, but in fact it is a refuge and training ground for awakened people-here, "treatment" means awakening the ability to "fate correction".
