Apocalypse no Toride

Yoshiaki Maeda is wrongfully imprisoned at Shouran Institute, a juvenile detention center in the Kanto region, where he is placed with other delinquent youths. Adjusting to life in a violent and chaotic environment proves difficult for the ordinary Yoshiaki. He is soon drawn into conflicts after bonding with his cellmates—Iwakura, Yamanoi, and Yoshioka—who are involved in ongoing disputes within the facility. The situation escalates when a prison transport crashes into the institute, and the wreckage reveals flesh-eating zombies. The facility descends into chaos as fear and horror take hold, marking the beginning of a desperate struggle for survival.
