When bizarre creatures known as the Noise threaten the Earth, only popular singing duo Zwei Wing has the power to fight back. But what happens after one of the idols sacrifices herself to save a civilian girl?

It's been one month since Hibiki's first battle. As she slowly adjusts to life as a Symphogear user, her grades start to plunge. After much effort, she finally turns in her make-up report and is free to look forward to the meteor shower that night. But then she gets another call...

A new relic wielder has appeared, and she's not friendly. Even worse, she's using the Nehushtan Armor, which was stolen in the attack on the concert two years ago. Tsubasa loses control of herself and prepares to sing her Superb Song...

The Japanese Government has decided that the enemy is getting too close to Durandal, the powerful intact relic kept at the bottom of the Abyss. They want to move it to a secure location, which means transporting by car. But the Noise are sure to notice, which means a high-speed car chase through a dangerous chemical plant.

As Hibiki is spending more and more time fighting the Noise, it means less time for her studies and less time for her friends. Miku is feeling alone and isolated, but she makes a promise with Hibiki to go get some snacks after school. But when school ends, Hibiki gets another call...

Hibiki and Tsubasa work together to defeat Chris, who runs away. But now Miku has seen Hibiki fighting, and she's very upset that Hibiki's been keeping secrets...

Miku is still upset that Hibiki didn't tell her about the Symphogear. She starts skipping school and binging on Okonomiyaki, but she's caught outside during another Noise attack...

Chris is alone and scared, and cut off from anyone who could help her. She's living out of an abandoned building in the evacuated zone, when she's met by an unlikely friend. Meanwhile, Tsubasa has recovered enough to start fighting again. To celebrate her return, Hibiki decides to take her on a date!

Chris finally joins Division 2, and she brings with her valuable information: the name of the project that Finé is working on. But before they can get there to stop her, four massive flying Noise appear in the skies over Tokyo.

Kadingir is complete, and Finé's master plan is revealed. She's going to shoot a giant rail gun at the moon, and blow it up!

Hibiki goes out of control, and Tsubasa is defeated by Finé. Everything looks lost when Miku reactivates the power to the school, and the other students start singing the anthem over the speakers...

With their new unlimited gears, the Symphogear warriors easily defeat Finé's legions of Noise. But Finé has a final plan: Absorb the Noise and become a huge, laser shooting monster!
