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 with a neighboring nation. 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. Sora no Woto is a single-season anime original which also was adapted as a short manga and a visual novel.

Sora no Woto’s locations were closely based on Cuenca in real-world Spain, with some slight differences in terms of the story’s fantasy religious and geopolitical elements.
