Two years ago, a pair of idols, Tsubasa Kazanari and Kanade Amō, collectively known as ZweiWing, fought against an alien race known as Noise using armor known as Symphogear. To protect a girl named Hibiki Tachibana, who got severely wounded by the Noise, Kanade sacrificed herself. Two years later, as Tsubasa has fought the Noise alone, Hibiki ends up gaining the same power as Kanade.

Swan Song of the Valkyries: Symphogear) is a Japanese anime television series produced by Encourage Films, with production assistance from Satelight, which aired on Tokyo MX between January 6, 2012 and March 30, 2012.
