In AD 2067, deep within the Brisingr Globular Cluster, a mysterious disease called “Vár Syndrome” begins infecting humans and Zentradi alike, causing them to go berserk and resulting in massive loss of life and property.
An interstellar enterprise known as Chaos forms Delta Flight and the tactical sound unit Walküre to counteract the spread of the Var. Walküre’s idols’ power lies in their singing, which contain powerful “bio-fold waves” that help calm those infected with the disease. Mikumo Guynemer, Kaname Buccaneer, Makina Nakajima and Reina Prowler tour system to system in hopes to quell the symptoms of the disease.
At the same time, an elite variable fighter unit known as the “Aerial Knights” of the “Kingdom of the Wind”. Led by King Gramia VI, Heinz Nehrich Windermere and Roid Brehm, they openly declare war on the New United Nations Government for war crimes they committed in their home system of Windermere seven years ago.
Caught in the conflict is would-be Walküre idol Freyja Wion and Delta Flight pilots Hayate Immelman and Mirage Farina Jenius. They will soon be entangled with the mystery of the Protoculture’s legacy of the Star Singer. The curtain is raised for the story of passionate teamwork and love larger than a star system.
