Off Village: Daisanbou Okabe

Overview

In that village, those who die rise again, transforming into what the locals call "Wandering Dead" that are neither fully alive nor completely dead. These wandering dead then feast on the living... In the remote settlement of Sarugami Village, completely isolated from the outside world by three imposing walls and absent from all maps, an eerie phenomenon unfolds. The villagers know nothing of the outside world, they can only resist the suffocating scent of death that permeates their lives... It's a bizarre horror where conspiracy and madness intertwine.
