Volume 1

Short summary
Ganta Igarashi experiences a mass-murder in his school by the Red Man, but is framed to have done it himself. He is sentenced to death and is sent to Deadman Wonderland. There, he meets with Shiro, a strange albino-girl, and Azami Midō. The promoter tried to carry out Ganta's death sentence by crushing him under a boulder, but Ganta destroyes it using a strange power, his Branch of Sin. He faints after that.

After recovering, Ganta and Shiro decide to participate in one of the prison's events, the Dog race show. But he finds out that he has to win the race or else he'll die the next day. One of the rewards is a Candy, which he needs in order to live. He survives the race, with Shiro protecting him the whole time. In the end, he gives up victory to save Shiro.

Back in his cell, Ganta meets Yō Takami and he gives Ganta Candy. They walk in the yard as the Red Man appears. The Red Man uses his Branch of Sin to destroy the whole yard, including the prisoners. Yō and Ganta survive, with Ganta firing his Branch of Sin at the Red Man. Ganta faints again after the Red Man walks away.
