When bizarre creatures known as the Noise threatens the Earth, only popular singing duo Zwei Wing has the power to fight back.

When young Hibiki is attacked by the Noise, she suddenly transforms into an armored warrior to fight them off.

As Hibiki slowly adjusts to life as a Symphogear user, her grades start to plunge, and after much effort she turns in her make-up report.

An unfriendly new Symphogear user has appeared using the armor of Neshutan, which was stolen in the attack on the concert two years ago.

The Japanese Government has decided that the enemy is getting too close to Durandal, the powerful and intact relic kept at the bottom of the Abyss.
