In 2050, the United Nations established the Scavenger Control Division (SCD) to combat rogue scavengers possessing extraordinary abilities. Fifteen-year-old Fujita Enkai, a skilled SCD operative, is assigned an undercover mission: infiltrate an all-girls academy to monitor potential threats and gather intelligence. As the sole male student,

Fujita must maintain his cover and conceal his true identity. Only his mother, the school's principal, knows about his "Secret Mission."

Fujita's dual life—student and SCD agent—demands constant vigilance. He must blend in while discreetly gathering information, a challenge that keeps him on edge. The safety of countless lives depends on his success, motivating him to leverage his resourcefulness, intelligence, and training.

Beyond intelligence gathering and threat assessment, the mission becomes a journey of personal growth.
