Synopsis

Humans have been menaced by mysterious monsters called `Designated Aberrant Disaster: Noise`. Tsubasa and Kanade are a popular vocal unit. Two years ago, the pair of idols, collectively known as ZweiWing, fought against the alien race 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 Kanada.
