Reborn in a void between worlds, he encounters an otherworldly presence and a mysterious statue promising power beyond mortal limits. Transformed and thrust into "The Celestial Arena," Sebastian must navigate a world where morality shifts and every decision matters. As an extra in this new reality, he experiments with his strange abilities while facing allies, rivals, and enemies who challenge both his strength and his grasp of wielding life and death. The boundary between salvation and destruction grows increasingly fragile. Now Sebastian confronts an ultimate choice: fully embrace his powers to remake existence according to his will, or sacrifice everything to restore balance. His decision will determine the world's fate and prove whether even a shattered soul can leave an eternal mark.
