Superb Song of the Valkyries: Symphogear
After the Luna incident, Tsubasa Kazanari and foreign idol Maria Cadenzavna Eve perform a joint duet together. Much to everyone's surprise however, Maria makes a declaration of war against the world with her own dark Symphogear. Hibiki, Tsubasa and Chris are tasked with stopping Maria, Kirika and Shirabe.
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...
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.
The Moon is going to crash into the Earth, and there is no way to stop it. Finé's plan has been to raise the floating continent of Frontier in order to survive, but they lack the needed technology. They attempt to make a deal with the American government, which betrays them instead. Ver's Noise intervene to save them, but Hibiki is nearby, and she's forced to transform to survive.
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.
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.
