Intro
A dull, cloudy sky. A cityscape turned to dust. Time has passed, and weathered concrete is exposed to the strangely dry 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.
But in this place where nothing should be, two shadows moved.
Wow, look at this, Guest-kun!! He lanky limbs stretch out as he pulls something from the gaps in the rubble.
Hehe, this looks like it'll make excellent research material. Fuhi, hi, hihahahaha!!
