Across the galaxy, a mysterious condition known as Var Syndrome is turning ordinary people violently uncontrollable. The tactical sound unit Walküre uses the power of song to suppress outbreaks, protected in battle by the skilled pilots of Delta Flight.

Freya Wion, a young woman from the isolated Kingdom of Windermere, dreams of singing with Walküre and crosses paths with carefree pilot Hayate Immelmann. Their arrival coincides with a new conflict as Windermere's Aerial Knights challenge the New United Government, pulling Hayate, Freya, and Walküre into a war where music, flight, and the truth behind Var Syndrome are closely intertwined.
