Humanity is finally confronted with the threat of the Custodians—the ancient, sentient species held responsible for cursing humanity to speak different languages thousands of years ago. The Symphogear wielders—Hibiki Tachibana, Tsubasa Kazanari, Chris Yukine, Maria Cadenzavna Eve, Kirika Akatsuki, and Shirabe Tsukuyomi—are sent to the Antarctic in order to retrieve an ancient relic. After securing it and rescuing the scientific staff present there from a Coffin, the automated defense mechanism protecting it, the relic is given to American researchers due to international agreements. The criminal organization Noble Red, a remnant of the previously fought Bavarian Illuminati, starts targeting the relic. Will the Symphogear wielders and their supporting organization S.O.N.G. be able to foil the plans of the organizations conspiring against them?

To the students of Karai High School, Nanako Yukishiro is a pretty, calm, and cute 16-year-old. However, Nanako is no ordinary girl, as she cannot speak! Instead, Nanako communicates through senryuu—17-syllable-long poems. Sixteen-year-old Eiji Busujima used to be delinquent in his middle school years. However, he has since turned over a new leaf due to his newfound love of senryuu. Despite his menacing looks, Eiji gets along well with Nanako as a fellow member of the Literature Club. Even though Nanako is mute, the adorable pair have no problem communicating with each other. Senryuu Shoujo is a light and relaxing story of two teenagers' daily lives.

The year is 1931. The city is Shanghai. Ten years before America will enter World War II, the hydra's teeth planted by the first great global conflict are beginning to germinate. Hatching like spiders, they weave the complex web of plots and conspiracies destined to inevitably draw entire nations to the brink of destruction. Caught in the heart of these webs, desperately seeking to separate lies from truth, is Sakurai Kikan, an ultra-secret intelligence agency staffed by extraordinarily talented individuals with abilities far beyond those of normal humans. Their duty: to stop the darkest plots and eliminate the greatest threats. But in a city built on intrigue, can even a team of clairvoyants, telepaths and espers stand against the ultimate forces of destiny? (Source: Sentai Filmworks)
