After a daring escape from the Memory Museum, Sayaka Miki returns to Mitakihara City with unsettling news. Troubled by what she has learned, Sayaka reveals to Madoka Kaname and Homura Akemi the whereabouts of Mami Tomoe—but more importantly—the disturbing truth behind the existence of magical girls. Despite knowing the cruel fate that awaits them, the three quickly resolve to work together and save Mami once and for all. Meanwhile in Kamihama City, Yachiyo Nanami hunts various "rumors" in search of Hotel Fendt Hope, the headquarters for the Wings of Magius. The magical girl organization is Yachiyo's only lead in finding Iroha Tamaki, whose disappearance remains shrouded in uncertainty. Determined to reunite Team Mikazuki Villa, Yachiyo swears to destroy the Wings of Magius and put a stop to their insidious plans. Amidst the turbulent situations, a calamitous threat approaches, presenting a dire conflict set to jeopardize the entire world.

In the technologically and magically advanced Wahrheit Empire, rumors of a returning catastrophe known only as the "light" causes a disturbance amongst the people. Meanwhile, in the capital of the Empire, transporter Innumael Grauer prepares his daily deliveries, struggling to make ends meet for himself and his sister. Leocadio Wöhler, a newly recruited soldier, assists Innumael whilst commuting to work—unknowingly loading a mysterious package containing contraband artillery belonging to a criminal organization.

Innumael is accused of smuggling the package, facing possible execution due to the Empire's strict oversight of weapons in response to the rising disorder. However, unbeknownst to him, the very syndicate that placed him in this unfortunate predicament may save him from this fate, at least temporarily. Elsewhere, Leocadio is assigned his first mission—to apprehend the criminal group known as "Headkeeper," suspected of transporting illegal weaponry.

Magatsu Wahrheit: Zuerst follows these two young men on a journey encompassing the Wahrheit Empire, triggering a chain of events that will not only change their lives but also alter the course of the Empire as they know it.
