Over a hundred days after the Lunar Attack, Hibiki and Chris are carrying the Staff of Solomon to an American military base. The train they're on is suddenly attacked by Noise, and the Noise seems to be being controlled.

Maria summons Noise and attacks Tsubasa at the Queens of Music concert. If Tsubasa wants to transform and fight back, it will mean revealing to the entire world that she is a Symphogear wielder.

Headquarters tracks Finé's base to an abandoned hospital outside town. When the Symphogear wielders attack the base, their powers are weakened by a strange red gas, and they are attacked by a monster which doesn't seem to be a Noise...

Maria and Tsubasa fight a battle on top of the Section 2 submarine. After Maria escapes, the wielders return for the school cultural fair. Chris is drafted into a singing competition, but just as she's about to win, a surprise challenger appears.

Kirika and Shirabe sing "Orbital Beat" at the school singing competition. Not wanting to fight them at the school, the wielders agree to fight a duel at another place. But when they arrive, instead of the girls they find Dr. Ver.

After being seriously injured by the Nephilim, Hibiki is unable to control her Symphogear. She flies into a rage, destroying the Nephilim and ripping out its heart. During the post-fight medical exam, it's discovered that if she continues to use her gear, she'll die.

Kirika and Shirabe attempt to recover Dr. Ver so that he can treat their mom. They run into Hibiki, whose fusion has progressed to the point where she can touch a Noise with her bare hands. Dr. Ver injects them with a LiNKER boost, and they attempt to use their Superb Songs, which might kill them.

Miku is missing after the explosion at the Sky Tower, but there's hope she might still be alive. Despite the danger, the wielders decide to try and recover her from Finé's clutches.

Dr. Ver arms Miku with a Symphogear, both in order to raise Frontier and defeat the wielders. His use of LiNKER means that any serious shocks could kill her. Hibiki tries to stop her, but she only has two minutes and forty seconds before the overload from her Gear kills her as well.

Hibiki's gear is destroyed, Chris has gone rogue, and the floating continent is raised. Only Tsubasa is left to fight Dr. Ver and the rest of Finé. With no one else to help them, Division 2 turns to Shirabe.

Dr. Ver's activation of Frontier has brought the Moon closer to crashing on to the surface. Maria and her mom have a plan to stop it, but they need the help of everyone on Earth to do it. And after everything that's happened, Maria doesn't feel like she can...

Dr. Ver's plans to murder most of humanity and make himself king have failed, so he sets the Nephilim's reactor to explode. With only minutes before it blows up into a trillion-degree heat, the Symphogear wielders must use all their power to stop it.
