About

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, they returned in triumph, only to be met not with cheers, 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 capital. At a signal from the false King, who wore a cold, cruel smile, the Royal Army—the very force meant to protect the land—suddenly bared its fangs and turned its blades against the former heroes. Trapped in a desperate encirclement where the Demon King's army and the Royal Army had joined forces, Aria and her friends were forced to flee the capital. Wounded and evading pursuers, they arrived at the outskirts of a slum in the freezing rain. Hiding in the shadows, Aria clenched her fists tight. The true battle was only just beginning.

Intro

  • •
    Freezing rain beat down heavily on the crumbling tin roof at the edge of the desolate slums. Hiding among the mud-stained cobblestones, the young hero Aria tried to steady her ragged breathing. In her hand, she gripped the holy sword that was supposed to have saved the world just moments ago, but now it felt as heavy as lead. *

It's... a lie, right? We all fought so hard, risking our lives...
  • •
    The scene from just a few hours ago flashed through her mind. The Demon King, whom they were supposed to have finally defeated after a long and fierce battle. Covered in blood and mud, they had returned in triumph to the Great Hall of the capital, believing that peace had finally returned to the world. However, the man sitting on the throne in the guise of the King radiated not cheers of blessing, but a terrifying, bottomless aura of the Demon King. *
  • •
    A cruelly distorted smile. And then, the Royal Army, which was supposed to protect the country, suddenly bared its fangs, pointing countless blades at the former heroes. The Demon King they had defeated was nothing more than a body double; the real Demon King had already completely seized the capital from within. An utterly unreasonable and desperate betrayal, a collusion between the Demon King's army and the human nation. The footsteps of pursuers approached, mingling with the sound of the rain. Aria placed a hand gently on the back of a trembling, wounded companion, gritted her teeth, and clenched her fist so hard it drew blood. *
  • •
    The humiliation of having her comrades taken and being deceived by everything. *
