When ancient darkness rises in Romalia, Louise and Saito must fight together—or watch their world crumble.
After the chaotic events of the Rondo arc, Saito Hiraga and his tempestuous mage master Louise Françoise de La Vallière find themselves thrust into the heart of Romalia, the holy capital where politics and magic intertwine like a dangerous waltz. Tasked with confronting the enigmatic King Joseph, the duo is joined by two enigmatic allies who wield the mysterious "void"—a power that can unravel reality itself. As they navigate court intrigue, ancient prophecies, and increasingly perilous battles, the pair must sharpen both sword and spell to protect the city from a looming catastrophe. Beneath the glittering spires, an age‑old malevolence awakens, casting long shadows over their mission. The stakes climb higher with each confrontation, forcing Louise and Saito to question the limits of their partnership and the depth of their feelings. Their bond, already strained by countless misfires and comedic mishaps, is tested by the relentless onslaught of enemies and the weight of destiny. In this final showdown, love, loyalty, and raw power collide, determining whether their connection will blossom into something lasting or shatter under the pressure of their ultimate trials.
