So Ra No Wo To follows Kanata Sorami, a young woman who joins the Helvetian army in the quiet town of Seize. Her main goal is to learn the bugle, a dream inspired by a moving performance she once witnessed.
She's assigned to the 1121st platoon, stationed at a Clocktower Fortress, alongside a small group of women: a skilled trumpeter, a reserved mechanic, an energetic gunner, and their compassionate captain.
The series explores their daily lives, their relationships, and their experiences in Seize, a town seemingly untouched by the growing tension between Helvetia and the Roman Empire. They find joy and meaning in their community and their shared experiences, even as the world around them faces uncertainty.
The story focuses on Kanata's personal growth, her learning the bugle, and the bonds she forms with her fellow soldiers in the backdrop of a potentially volatile political landscape.
