Trapped in a world that shouldn’t exist, survival is only the beginning of their nightmare. A routine day at Tenjin Elementary turns into a nightmare when an entire school building mysteriously disappears, stranded in a barren wasteland. Students and teachers must struggle to survive in this hostile, post-apocalyptic world, facing hunger, madness, and each other as society collapses around them. Kazuo Umezz’s Drifting Classroom is a harrowing, suspense-filled horror classic that blends psychological terror with survival drama in a story that has haunted readers for decades.
