Qiang Niang primarily follows the protagonist Carrie, who has lost her combat memories, as she searches for her identity and the story of her final "Awakening". Between 2025 and 2030, a global world war has led to the death of half the world's population, and humanity has already lost control over the war's direction. To secure ultimate victory, warfare has gradually evolved into a depopulated conflict, resembling a game. Combat now centers on satellite lasers, bomb drones, intelligent AI, and a battlefield of unmanned gun turrets and tanks... Then there is also a group of young maidens who use outdated firearms to fight —— the Gun Girls.
