In a lonely corner of the world, on the edge of No Man’s Land, sits Clocktower Fortress. It’s home to the 1121st Platoon of the Helvetian Army, and their newest member is a 15-year-old volunteer named Kanata Sorami, who enlisted to learn how to play the bugle. When she was a child, Kanata was saved by a beautiful soldier and found inspiration in the clear, golden sound of her trumpet. From that day forward, Kanata decided music would be her life. As the other platoon members train her how to be a bugler and a soldier, Kanata's enduring optimism will inspire them to look for happiness and beauty, even in a world haunted by war.

The OVA features six separate stories revolving around the cast, some of which border on the bizarre; one of which is an MMORPG environment being played by Konata, Kagami, Tsukasa, and Nanako Kuroi, and another in which Kagami has a "suggestive" dream about Konata.
Summer has arrived at last, and with it comes the promise of summer break for the students of Lillian Girls’ Academy.

These wealthy snobs turn up their noses at Yumi and Sachiko’s relationship — and if Yumi isn’t careful, her blissful summer at Sachiko’s side could come to an abrupt and tearful end.
