Senki Zesshou Symphogear

First Season: Senki Zesshou Symphogear
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.

Second Season: Senki Zesshou Symphogear G
Peace had seemed to return to the world when Hibiki, Tsubasa, and Chris had saved the planet from the Luna Attack with their song. However, 3 months later at a joint concert between Tsubasa Kazanari and foreign superstar Maria Cadenzavna Eve, the Symphogear team is faced with her dangerous declaration of war against the world. Maria and her allies Kirika and Shirabe have a fearful power backing them: The power of the dark Symphogear.
