A mysterious girl appears at my doorstep, claiming to be a time traveler fleeing a devastated future. She reveals an impending catastrophe—civilization will crumble, monsters will overrun the world, and reality itself will fracture beyond salvation. Stripped of her abilities and vulnerable, she's trapped in my care. As apocalypse looms, I must decide: keep her confined for protection, or trust her warnings about the coming darkness that threatens everything I know.
