Battle for the Imperial Capital

The Decisive Battle for the Imperial Capital (帝都決戦) is the name given to a major battle that took place in the Sacred Vollachia Empire approximately one year and five months after Natsuki Subaru was summoned to the world. It was a crucial conflict during the latter part of Arc 7, revolving around a battle for control over Imperial Capital of Lupugana by the Imperial Army, Natsuki Subaru’s Pleiades Battalion, and a loose collection of individuals—including the Emilia Camp, the Priscilla Camp, Serena Dracroy’s Flying Dragon Squadron, members of the Imperial Army, and numerous rebels who began uprisings all throughout the Empire—colloquially known together as the Rebel Army.

The battle was Vincent Abellux's apparent attempt to reclaim his throne after he was deposed by Chisha Gold and Berstetz Fondalfon. In actuality, however, it was a precursor to the Great Disaster, a predestined disaster said to bring ruin to Vollachia after the death of “Vincent Vollachia”. With the help of the Stargazer, Ubilk, Abel confronted Chisha in an attempt to fulfill the prophecy and end his own life, but the Fourth ranking Divine General, who was posing as Vincent Vollachia, took the then-former Emperor's place to realize the forecast of Vincent Vollachia's death. The Great Disaster begins immediately following this.
