Over the 100 days since the Lunar Attack, Tsubasa and Chris are carrying the Staff of Solomon over to an American military base. The train they're on is attacked by the Noise, but they seem to be controlled by someone else.
Maria summons Noise and attacks Tsubasa at the Queens of Music concert. If Tsubasa transforms and fights back, she'll have no choice but to reveal to the world that she is a Symphogear wielder.
Headquarters tracks Finé's base to an abandoned hospital outside of town. When the Symphogear wielders attack the base, their powers are weakened by a strange red gas, and they're attacked by a monster who doesn't seem to be a Noise.
Maria and Tsubasa fight on top of the Section 2 submarine. After Maria escapes, the wielders return for the school cultural festival. Chris is drafted into a singing competition, but just as she's about to win, a new challenger appears.
Kirika and Shirabe sing "Orbital Beat" at the school singing competition. Not wanting to fight at school, the Symphogear wielders decide to duel at another place. But when they arrive, instead of finding the girls, they find Dr. Ver.
After being heavily injured by the Nephilim, Hibiki is unable to control her Symphogear. She becomes enraged, destroying the Nephilim. But during a medical exam, it's discovered that if Hibiki continues using her gear, she'll die.
Kirika and Shirabe run into Hibiki, whose fusion has progressed to the point that she can fight a Noise with her bare hands. Dr. Ver injects them with a LiNKER boost, and they attempt to use their Ultimate Songs, which may kill them.
Miku is missing after the explosion at Sky Tower, but there's hope she may 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 to raise Frontier and defeat the wielders. His use of LiNKER means any serious shocks could kill her. Hibiki tries to stop her, but she has to before the overload from her gear kills her too.
Hibiki's Symphogear is destroyed, Chris is gone 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, the wielders turn to Shirabe.
Dr. Ver's activation of Frontier has brought the moon closer 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 she's done, Maria doesn't feel like she can.
Dr. Ver's plans to murder most of humanity have failed, so he's set 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.
