Sora no Woto - Sound Of the Sky

I watched this opening and liked because of the amazing art, I love the different openings because they are unique and not cliche.
(Wait second untill the video appears)

This is a great anime, I recommend it.
Plot: 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) in Helvetia (another name for Switzerland), where she is taken into the care of 2nd Lt. Filicia Heideman, M/Sgt. Rio Kazumiya and the rest of the 1121st Platoon. 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.
