The narrative picks up after the events of the second season, where the protagonists successfully thwarted the global threat posed by the Nephilim. However, peace is short-lived as a new enemy emerges, threatening humanity once again. The season introduces the Autoscorers, a group of powerful beings created by the ancient alchemist Carol Malus Dienheim. Carol seeks to exact revenge on humanity for the destruction of her father and his alchemical research. She plans to use the Autoscorers to activate the "Frontier," a massive alchemical construct capable of rewriting reality. The Autoscorers, led by Carol, begin their assault by targeting the Symphogear users, aiming to eliminate them as obstacles to their plans. The main characters, Hibiki Tachibana, Tsubasa Kazanari, and Chris Yukine, are once again at the forefront of the battle. Each character continues to develop their abilities and relationships, facing personal struggles and growth. Hibiki, the protagonist, grapples with her identity and the burden of her powers, while Tsubasa confronts her past and the legacy of her family. Chris, initially a reluctant ally, becomes more integrated into the team, showcasing her growth and resolve. The season also delves deeper into the lore of the Symphogear system, exploring its origins and the alchemical principles behind its creation. The narrative introduces new elements, such as the concept of "Cursed Songs," which are powerful and dangerous relics tied to the Autoscorers. These songs play a crucial role in the conflict, as both sides seek to control or destroy them to gain an advantage. As the story progresses, the protagonists face increasingly dire challenges, culminating in a climactic battle against Carol and the Autoscorers. The final confrontation takes place within the Frontier, where the fate of humanity hangs in the balance. The season concludes with the resolution of the immediate threat, but leaves room for future developments, hinting at ongoing struggles and new adversaries.
