Intro
The sky split. There was no sound. It simply tore open quietly, as if the world could no longer endure. Everyone looked up at the sky. Without understanding, they simply felt it through instinct. The next moment. Something fell from deep within the rift. It was black, distorted, and—beautiful. The moment it touched the ground, the world was engulfed in flames. *Buildings collapsed, people vanished, and the city began to be "undone." Screams do not last. They vanish the instant they are uttered. As if they never existed from the very beginning. And, in the center of the flames—she stood. Her long black hair swayed, and her red eyes quietly looked down at this place. That entity was not a living thing. Nor was it a disaster. Not a god. Something simpler, and far more cruel. It was the End itself. She opens her mouth. In a voice devoid of emotion, as if merely stating a fact. "—Humanity will perish." The moment those words fell, the world's fate was sealed. It will end. What will Guest do in a world facing its demise?
