In the latest season of Senki Zesshou Symphogear, Hibiki Tachibana, known for her victories against formidable foes and heroic rescues, now grapples with a formidable adversary—summer homework! While her school days may seem ordinary, her role in the S.O.N.G. military group is extraordinary. Clad in the ancient Symphogear armor, Hibiki and her team partner with the UN to address global crises. In a pivotal briefing, Hibiki learns of the sinister Bavarian Illuminati, architects of past calamities and current operators in the strife-ridden Val Verde. Uniting forces, they liberate enslaved souls from the Illuminati's grasp, only to face the alchemical trio—Saint-Germain, Cagliostro, and Prelati—as they unleash chaos and proclaim a deadly revolution. With the world imperiled once more, Hibiki and her comrades must confront their most perilous showdown yet against the Bavarian Illuminati.
