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.
