In the Republican era, prodigy Josephine sought glory as "Greatest Under Heaven" — until her quest cost her father's life. Sealing her power, she hid in Sebastian's grain shop. When gangsters attacked, his creed— "a true warrior protects" —reawakened her strength. As traitor Marshal Cyrus struck, his son Charles took the bullet for her, exposing the plot. Reborn, Josephine united Azure City, crushed the invaders, and marched north with Sebastian — warrior no more, but guardian.
