Senjou no Valkyria: Gallian Chronicles

A fictional continent modeled after 1930s Europe is divided between two dominant powers: an eastern monarchy and a western democratic alliance. A crucial resource, ragnite, is central to both military and medical applications, fueling ongoing conflict between the two sides. The narrative unfolds in Gallia, a neutral region rich in ragnite, after it is invaded by the eastern power seeking to claim the resource. The group includes Welkin, a young man with a military background; Isara, his adopted sister from a different ethnic group; and Alicia, a local law enforcement member. They join Squad 7, a loosely organized militia, to resist the invasion. Welkin leads the unit and commands a tank, Alicia serves as a scout, and Isara pilots the tank. The squad consists of various other individuals united in their effort to defend their homeland.
