The elder Kazanari's meddling has awakened Shem-ha, the powerful Goddess from the depths of time. The Symphogears must stop her before she remakes the Earth in her own image.

The Symphogears travel to the moon and discover the terrible truth about the creation of the curse: It wasn't a way to harm humanity, but a way to keep it alive.

Despite Elfnein and Carol's attempt to stop her, Shem-Ha begins using the world's computer networks to have Yggdrasil cover the entire globe in a barrier. Back on the moon, Hibiki and Chris face off against Vanessa, ultimately saving her and the others from being sucked into space. However, Shem-Ha takes control of Vanessa and uses her to install a virus in the Marduk's network in order to destroy it, forcing Noble Red to use the last of their strength to send the wielders back to Earth, resulting in their deaths similar to how Saint-Germain and her friends risked their lives to save the others.
