A murder of a family occurs in Gotenyama, Musashino City. The case is called "Code 5" and is handled through a different route than usual. A few days later, Sudou Hiromi, the investigator assigned to the case, receives a disturbing call. Houshou Aiko, the girl who was the victim in the incident, has come back to life. Sudou rushes to the research institute where Aiko is being held. There, he hears that Aiko's return to life is an "anomaly," an event that cannot be described as a miracle. In fact, Aiko had a "deformity" in her left arm.
