Sound of the Sky
On the outskirts of the country of Helvetia rests the tranquil town of Seize. Upon its cobbled streets, citizens go about their daily lives, undisturbed by the increasingly tense military relations between Helvetia and the neighboring Roman Empire. It is under these circumstances that the 1121st platoon of the Helvetian army, stationed at the Clocktower Fortress in Seize, receives a new recruit in the young and spirited Kanata Sorami. Having joined the military to fulfill her dream of learning to play the bugle, she excitedly accepts the tutelage of the Sergeant Major, Rio Kazumiya, who happens to be a skilled trumpeter. Working alongside them are the aloof mechanic, Noël Kannagi, the feisty gunner, Kureha Suminoya, and the compassionate Captain Felicia Heideman; together, they experience the beauty of life in Seize and the lasting joy of a community that has persevered in spite of the crumbling world around them.

Confronted by soldiers from the 9th Division, Aisha suffers serious injury in front of a frightened Noël. Meanwhile, Filicia takes Col. Hopkins hostage and orders his forces to leave the fortress as they barricade themselves inside. Col. Hopkins divulges his intention to use Aisha to instigate war, in addition to revealing his connection with Noël who once worked with him in reconstructing an ancient bioweapons technology that resulted in the deaths of many people. After being locked up in the distillery, he manages to make his escape in secret. While on tower patrol, Kanata hears a faint and distant signal for cease-fire prompting her to tell the others. Naomi with the support of the townspeople try to convince the 9th Division of the signal for cease-fire but are arrested by Col. Hopkins. Out of options and with an injured Aisha in tow, the girls decide to use the restored Takemikazuchi to stop the 9th Division and prevent all-out war between the nations.
