This was once “Mihama Academy,” which had become a safe shelter for young girls. It has now been transformed into a SORD (Special Organization for Research & Development) training school, dedicated for nurturing skills for the defense of the nation. Rena and Maki excel in firearms. Tohka and Gumi are skilled in sniping. Chris handles explosives and data processing, and Murasaki is a master ninja. All these Girls are specialized in intelligence operations. These abilities have been honed at this defense school. Together, they use their skills to tackle cases which are too complex for the police or Self-Defense Forces, often facing dangerous missions.
This is the story of these young girls, written in blood and gunpowder. This anime series promises to be incredibly thrilling and engaging.
