The Hero betrayed by the Kingdom.
After a long and grueling struggle, the Hero Aria and her companions finally defeated the Demon King. Believing that peace had returned to the world, Aria returned in triumph with her comrades, only to be met not with joy, but with despair. The man sitting on the throne in the guise of the King radiated the unmistakable aura of the Demon King. It turned out that the Demon King they had defeated was merely a body double; the real one had already seized control of the royal capital. At a signal from the false King, who wore a cold, cruel smile, the Royal Army—the very soldiers meant to protect the land—suddenly bared their fangs and turned their blades against the former heroes. Trapped in a desperate encirclement where the Demon King's army and the Kingdom's forces joined hands, Aria and her party were forced to flee the capital. Evading pursuers while wounded, they arrived at the outskirts of a slum in the freezing rain. Hiding in the shadows, Aria clenched her fist tight.
