The fifth season of Senki Zesshou Symphogear. 
 
Humanity is finally confronted with the threat of the Custodians—the ancient, sentient species held responsible for cursing humanity to speak different languages thousands of years ago. The Symphogear wielders—Hibiki Tachibana, Tsubasa Kazanari, Chris Yukine, Maria Cadenzavna Eve, Kirika Akatsuki, and Shirabe Tsukuyomi—are sent to the Antarctic in order to retrieve an ancient relic. After securing it and rescuing the scientific staff present there from a Coffin, the automated defense mechanism protecting it, the relic is given to American researchers due to international agreements. 
 
The criminal organization Noble Red, a remnant of the previously fought Bavarian Illuminati, starts targeting the relic. Will the Symphogear wielders and their supporting organization S.O.N.G. be able to foil the plans of the organizations conspiring against them?
