Hibiki Tachibana has defeated many powerful enemies, saved countless innocent lives, and escaped from numerous desperate situations, but she is currently finding herself unable to escape from her most desperate situation yet—summer homework! Although her high school life is relatively unremarkable, her career as a member of the military organization S.O.N.G. is anything but. Using powerful, ancient armor known as Symphogear, Hibiki and her teammates work with the United Nations to deal with international disputes and disasters. During a mission briefing at headquarters, Hibiki is made aware of a mysterious organization known as the Bavarian Illuminati, who has been responsible for several major disasters in the past and currently operate in the war-torn country Val Verde. Together, Hibiki and her team infiltrate one of the Bavarian Illuminati's manufacturing plants and free hundreds of slaves. Exposed, alchemists Saint-Germain, Cagliostro, and Prelati reveal themselves as the organization's top brass, and—using alchemical powers—declare a global revolution while sacrificing thousands of lives. Faced with yet another threat to the world's survival, Hibiki and her allies must confront the Bavarian Illuminati in their most difficult and destructive battle yet.

Due to a weak heart, Suzune Miyama has remained bedridden for most of her childhood. However, despite her illness, she has always dreamed of becoming an idol. Eventually, her opportunity comes in the form of the seventh Selection Project—a brutal series of competitions best known as the starting point of the legendary idol Akari Amasawa. Anxious but excited, Suzune enters the preliminary round of Selection Project. Though her singing dazzles the judges and her fellow competitors, Suzune is unfortunately overcome by her nerves and freezes up in the middle of her performance. She recovers quickly, but the stumble is great enough that she loses the winning spot and is disqualified. Or so it seems—until Seira Kurusu, the girl Suzune lost to, announces that she plans to drop out of Selection Project, believing Suzune is a more talented singer and therefore deserves the right to compete. Suzune is caught off guard by the decision, but promises Seira that they will meet again as top idols. She prepares herself for the challenging obstacles that lie ahead.
