Sound of the Sky

A manga adaptation illustrated by Yagi Shinba began serialization in the January 2010 issue of ASCII Media Works' Dengeki Daioh magazine.

Sound of the Sky revolves around a young girl named Kanata Sorami who is inspired to join the military after witnessing a rendition of "Amazing Grace" by a mysterious trumpeter of the Helvetian Army.

Becoming a bugler, she is assigned to the 1121st Platoon stationed in the town of Seize (inspired by Cuenca, Spain)[2] in Helvetia (another name for Switzerland), where she is taken into the care of 2nd Lt. Filicia Heideman, M/Sgt.

The story takes place in a post-apocalyptic world after a great war regressed humanity's technological capabilities back to early-to-mid 20th century standards.

Before the anime's release, a manga adaptation illustrated by Yagi Shinba was serialized between the January 2010 and June 2011 issues of ASCII Media Works' Dengeki Daioh magazine.
