After crossing into Westland, Edward Quinn accidentally bonds with the drugged Princess Alexandra Lancaster. With King Richard gravely ill and Duke Clarence forcing a marriage alliance, Princess Alexandra takes Edward as her consort and sends him to the Six Gates Bureau as a probationary constable. On their wedding night, Edward activates the [Queen's Advisor System], rising as a martial master. He captures a Northmark spy, makes a name for himself, and befriends Lady Marianne Landon. Uncovering Reginald Linley’s treasonous plot, Edward wins a bet, seizes corrupt assets, and brings down Linley, earning the title Marquis Defender. He then foils Northmark’s marriage scheme, leads the Vanguard Battalion to quell Duke Clarence’s rebellion, and is promoted to Grand Marshal of the Army. Breaking through to the realm of a land deity, he unleashes “Blades of Unity” to shatter the Northmark forces. Edward helps Princess Alexandra ascend the throne, receives the title of “Prince of Equal Standing to the Emperor,” and achieves a perfect triumph.
