Fort of Apocalypse

Falsely accused and incarcerated, Yoshiaki Maeda finds himself confined alongside delinquents from across the Kanto region at Shouran Institute, a juvenile correctional facility. An ordinary boy at heart, Yoshiaki can imagine no worse fate than surviving the violence-ridden reality of prison life. His cellmates—Iwakura, Yamanoi, and Yoshioka—prove to be a shrewd and dangerous crew, and before long, Yoshiaki is dragged into an escalating internal conflict brewing within the walls. But when a prison transport van violently crashes into the compound, the true nightmare begins. From the wreckage shambles a horde of flesh-eating zombies, and what follows is a harrowing descent into panic and terror.
