Senki Zesshou Symphogear XV

Humanity faces a new threat in the form of the Custodians, an ancient species blamed for the division of human languages in the distant past. A group of Symphogear users—Hibiki Tachibana, Tsubasa Kazanari, Chris Yukine, Maria Cadenzavna Eve, Kirika Akatsuki, and Shirabe Tsukuyomi—travel to the Antarctic to recover an ancient relic. They successfully obtain it and rescue the scientific team from a Coffin, an automated defense system. The relic is then handed over to American researchers under international agreements. However, the criminal group Noble Red, a successor to the Bavarian Illuminati, begins targeting the artifact. The Symphogear wielders and their affiliated group S.O.N.G. must work to counter the schemes of those opposing them.
