Carrie wakes up as a weapon with no memory of who she was before the knife. The world reduced war to a game so humans wouldn't have to die anymore, then forgot that the girls fighting it were human. Watching her piece together her own past while the system that erased her tries to keep her useful is the real battle.
After a devastating global conflict reduces the world's population by half, humanity cedes control of warfare to satellites, drones, and AI systems. But the fighting continues anyway, mechanized and impersonal, until a group of young women armed with obsolete firearms prove something unexpected: human intuition and improvisation still matter on the battlefield. Carrie wakes up stripped of her combat memories, unsure who she is or why she can move like a soldier. Surrounded by other Gun Girls who operate in the shadows of an automated war, she begins piecing together fragments of her past while adapting to a world where outdated tactics have become revolutionary. Between firefights and rare moments of downtime, she and her squad navigate the strange liminal space they occupy: too human for the machines, too expendable for the generals who command them. The series balances action sequences with genuine comedy and quieter character moments, building toward the truth of Carrie's identity and what it means to "awaken" in a war designed to forget you exist.
