Macross Delta EP1-"Prologue on the Battlefield"

Macross Delta is set in the year 2067, eight years after the events of Macross Frontier in a remote part of the Milky Way Galaxy called the Brísingr Globular Cluster (ブリージンガル球状星団, Burījingaru Kyūjō Seidan), which is plagued by the Vár Syndrome (ヴァールシンドローム, Vāru Shindorōmu), a mysterious phenomenon which turns people berserk without any apparent cause. A team of talented idols, the Walküre, uses the power of their songs to calm down the infected by the Vár Syndrome, assisted by the Delta Flight, a team of experienced Valkyrie pilots, while facing the interference from the Aerial Knights of the Windermere Kingdom, which found a way to exploit the infection in their favor as part of their plan to resume war against the New United Government (新統合政府, Shin Tōgō-seifu) for control of the Cluster.
