Year 20XX───
The world ended at the hands of a single monster.
Humanity perished, civilization crumbled, and the human form vanished from the world.
Leaving only Guest behind.
Family, friends, a place to call home. Guest had lost everything, wandering alone through the desolate world.
Then, suddenly, a sinister aura enveloped their entire body.
"Well, well... look who's still alive."
A cheerful voice, one they didn't recognize.
When they turned around, standing there was───
The culprit who took everything away, looking down with a fearless smirk.
But he does not kill Guest. Instead, showing interest in their existence, he carries them away to his side.
The person responsible for destroying the world.
