Deadman Wonderland. 4

A post-apocalyptic story of survival in a surreal prison built in the ruins of Tokyo. Framed for the brutal murders of his classmates by the mysterious Red Man, middle school student Ganta Igarashi finds himself sentenced to death and sent to the bizarre and fatal theme park/prison that has risen from the ruins of the Great Tokyo Earthquake-a hell on earth known as "Deadman Wonderland." Ganta is recruited into Scar Chain, an antiestablishment group planning a mass prison escape. After a brief meeting with Shiro, he stands at a crossroads, but Nagi persuades him to take part in the escape. However, a traitor has already leaked the plan to the Undertakers, a unit specially formed to stamp out the rebels.
