Deadman Wonderland

Igarashi Ganta is having a normal school day with his friends, talking about their upcoming visit to the DeadMan Wonderland prison. Out of nowhere, a sadistic red man with superhuman powers appears, massacring everyone in the class but Ganta. Ganta is then wrongly accused of a murder he didn’t commit and placed in DeadMan Wonderland, where he meets his childhood friend Shiro and discovers a rare blood power known as the Branches of Sin within himself. He must then fight other Branches of Sin in the Carnival Corpse in order to earn enough for his freedom.
