Sound of the Sky
In a world that some say is dying due to ages of devastating wars, the physical and musical beauty of a female military trumpeter inspires young Kanata Sorami to eventually become a military bugler herself. Years later, during a supposedly-permanent cease fire between the nations of Helvetia and Rome, 15-year-old Private Kanata becomes the newest recruit in the five-member, all-female 1121st Platoon stationed at Clocktower Fortress near Seize, a town on Helvetia's border with a vast No Man's Land. Despite possessing perfect pitch, Kanata struggles at first to learn to play the bugle and trumpet properly but does better at integrating into everyday life with her platoon mates: 18-year-old Lieutenant Filicia, the very informal commanding officer; 17-year-old Sergeant Rio, an expert trumpeter who serves as a reluctant Big Sister to the younger members; 15-year-old Corporal Noël, a soft-spoken mechanical genius who concentrates on rebuilding the platoon's spider-like “old tech” tank; and 14-year-old Private Kureha, a serious-minded tsundere girl. All is not entirely calm and pleasant, however, for the grim specter of war still lurks in the background and Seize is, after all, the source of the legend of the tragic Flame Maidens – a legend which seems to fit the platoon members remarkably well.
