IN A SINGLE INSTANT, A SCHOOL OF 862 STUDENTS AND STAFF VANISHED FROM THE EARTH. THIS IS THEIR STORY. 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. Pursued by grotesque mutants, Sho and his friends flee back to the school, where more horrors await! Barricaded against the nightmares outside, the students must perform an emergency medical operation under the most primitive of conditions. As the survivors' resources dwindle, the countdown draws closer and closer to the end.
