Senki Zesshou Symphogear AXZ

Hibiki Tachibana can survive monsters and world-ending battles, yet summer homework is still a problem. Her ordinary student life is interrupted when S.O.N.G. sends her and the other Symphogear wielders to Val Verde, where they discover the Bavarian Illuminati exploiting a war-torn country for a vast alchemical operation.

Saint-Germain, Cagliostro, and Prelati step forward as the Illuminati's alchemists, seeking a revolution that requires sacrifices on a terrifying scale. Their experiments aim at power beyond conventional weapons, forcing Hibiki and her friends into a conflict over humanity's freedom, divine power, and whether ideals can justify the lives destroyed in their name.
