Out of nowhere, a Japanese elementary school is transported into a hostile world. Soon, the students and teachers must struggle to survive in impossible conditions, besieged by terrifying creatures and beset by madness. Part horror, part science fiction, The Drifting Classroom is a classic can't-put-down manga series from horror manga master Kazuo Umezu.

When a despotic student attempts to take control of the school, Sho tries to bring his classmates to their senses.

As the school is besieged, the students fight back desperately, weak with hunger. But this time, running out of food is the least of their worries. This time, they are food...
