Drifting Classroom 1

In the aftermath of a strange earthquake, an entire elementary school vanishes, leaving nothing but a hole in the ground. While parents mourn and authorities investigate, the students and teachers of find themselves somewhere far away,somewhere cold and dark, a lifeless, nightmarish wasteland among which their school stands like a lone fortress. As panic turns to terror, as the rules start to fall apart, a 6th-grade boy named Sho and his friends must try to survive in a hostile new world.

Kazuo Umezu is seen as one of the great manga horror masters and this is supposed to be 

one of his three most apocalyptic works, and probably his best known work in the west.

Drifting Classroom is very strange and scary and wholly unlike any horror stories!
