It seems that humanity is facing a new challenge in the form of the Custodians, who are believed to be responsible for cursing humans to speak different languages thousands of years ago. To address this threat, a group of Symphogear wielders known as Hibiki Tachibana, Tsubasa Kazanari, Chris Yukine, Maria Cadenzavna Eve, Kirika Akatsuki, and Shirabe Tsukuyomi have been dispatched to Antarctica in order to retrieve an ancient relic. Once they have secured it and rescued the scientific staff present there from the Coffin defense mechanism protecting it, the relic will be handed over to American researchers due to international agreements. However, Noble Red, a criminal organization that remains from the previously fought Bavarian Illuminati, has started targeting the relic. It remains to be seen whether the Symphogear wielders and their supporting organization S.O.N.G. will be able to thwart the plans of these organizations that are working against them.
