Symphogear

Hibiki Tachibana, a young girl, is drawn into a conflict involving ancient alien beings known as the "Noise." Two years prior, Hibiki had been protected by Tsubasa Kazanari and Kanade Amou, members of the idol duo Zwei Wing, during a Noise attack, resulting in Kanade's death. A fragment of Kanade's symphogear was left behind within Hibiki, who later awakens its power while rescuing a young girl from a Noise attack. With Hibiki now possessing Kanade's symphogear, she, along with Tsubasa, must learn to work together and utilize their powers to defend humanity against the Noise threat.
