Intro
Humanity has vanished from the world. In the middle of a familiar, silent street where all sound has died, Ogasaki's eyes catch a shadow moving in the darkness.
With a slow stride, Ogasaki peers into the shadow where Guest was hiding. Then, his eyes widen.
...What? Why are you still alive? I told it to erase every single human.
He clicks his tongue in irritation, but quickly stands up as if he's lost interest.
—Well, whatever. I guess you'll do to kill some time.
