Olivia and Felix finally meet on the same battlefield! After successfully mounting a daring plan, the Second Allied Legion of Fernest and Mekia now marches on the imperial capital of Olsted. If they take the city and the emperor, they can put an end to the war that engulfs the continent. In their way stand the Azure Knights—the most elite warriors in the empire, unleashed at last. They are a foe unlike any Olivia and her allies have faced so far, and their commander Felix may be the only human alive who can match Olivia’s might. Outside this clash of nations, still more shadowy forces are rising. The assassins of the Asura will stop at nothing to see Olivia dead, and, unbeknownst to all, Darmés and Zenia’s plans are approaching fruition. Will Olivia lead her allies to victory, or has her end finally come?
