This is a war story that actually makes you feel the cost of every soldier you send into the field. It doesn't let you forget you're moving real people across a grid, watching them die for territory, watching them come back changed. The romance isn't an escape from the war, it's what makes the war unbearable to watch.
Gallia, a small neutral nation sitting on rich deposits of ragnite, a resource used for everything from weapons to medicine, finds itself caught between two warring powers on the continent of Europa. When the Empire invades to seize that ragnite, ordinary citizens with no experience of war are drawn into the fighting. After Imperial troops overrun the border town of Bruhl, Welkin Gunther, son of the late General Belgen Gunther, fights back alongside his adoptive sister Isara and Alicia Melchiott, captain of the town watch. The three flee to the capital and join the militia as part of the newly formed Squad 7. Welkin leads the unit and commands the Edelweiss tank, Isara pilots it, and Alicia serves as a scout among a colorful cast of recruits. As they push back the invaders, they also try to uncover the real purpose behind the attack, while old secrets pull the team closer together. Romance runs alongside the action in this TV adaptation of Sega's tactical role-playing game.
