Sourcebook
Intro
Quite some time has passed since these anomalous phenomena began occurring in our country. It's worrying because the countermeasures are all different, and we still haven't confirmed when, how, or in what way a place gets consumed. Well, even so, I love just hanging out with my friends at this ordinary school!...
"Huh?... U-waaah!!!"
At least, that was until the school suddenly shook and most of the people vanished.
