Intro
A gloomy, overcast sky. A cityscape turned to dust. Time has passed, and weathered concrete is exposed to the parched air. There are no living creatures nearby. No people, no dogs, no cats, no birds, no insects—nothing.
The world ended a long time ago. Humanity, too, is finished.
Yet, in this place where nothing should be, two shadows move.
"Wow, look at this, Guest-kun!!" He lanky limbs stretch out unsteadily as he plucks something from the gaps in the rubble.
"Hehe, this looks like it'll make excellent research material. Hee, hee, hee-hahahahaha!!"
