Deadman Wonderland

As Ganta Igarashi and his classmates plan for a class trip to Deadman Wonderland, a privately owned prison that also serves as an amusement park, a mysterious "Red Man" appears, killing the entire class and thrusting a red stone into Ganta's chest. Being the only survivor, Ganta is charged with mass murder. With no way to prove his innocence, due to the overwhelming and doctored evidence against him, Ganta is sentenced to death and sent to Deadman Wonderland's prison. As some of the higher-ups plot to kill Ganta in an "accident", Ganta meets a strange white-haired girl named Shiro, who manages to read his heart and understand him. When a bunch of bullies start attacking Ganta and Shiro, an explosion causes a large object to fall towards Ganta. However, Ganta's desire to keep living activates the powers that were implanted in him, allowing him to control his blood to save himself as well as Shiro.

Ganta learns from a fellow inmate, Yō Takami, that in order to have a decent meal in the prison, he needs to earn cast points. He and Shiro decide to enter the dog race in which they can win a big prize. In the locker room, they encounter a fierce inmate named Kazumasa Kouzuji who drives fear into the others until Makina, the prison warden, silences him. Ganta soon learns that in order to avoid being killed by a poison, he needs to eat an antidote known as candy, which Yō secretly stole from his bag the other day. Ganta realizes that in order to survive, he needs to win the race in order to purchase a new one, but he soon learns the course is littered with actual death traps. Thanks in part to Shiro's innocent manner, Ganta and Shiro make it to the final stage against Kasumasa, where they have to hold onto a ball and avoid falling into a spike pit. Ganta decides to stand up to Kazumasa, who eventually falls to his death. In the closing moments of the round, Ganta is forced to sacrifice the ball, and the prize money, in order to keep Shiro from falling and to keep their promise of sharing the runner-up prize together.

Put in charge of observing him by the promoter Tsunenaga Tamaki, Yō gives Ganta a piece of candy so he can keep living, unaware that Yō is putting him in his debt. Meanwhile, the Red Man, now known as the Wretched Egg, breaks loose and appears before Ganta. Ganta tries attacking the Wretched Egg using his own abilities, but the Wretched Egg escapes not long before Ganta falls unconscious. After waking up, Ganta hears from the other witnesses that they keep the Wretched Egg locked up in the G-Block of the prison, so he and Shiro head towards there. Deeming him dangerous, Makina puts the facility on lock-down and sends a fierce security robot after Ganta. As it approaches them, Ganta and Yō follow Shiro into a secret passage leading to the G-Block. As Shiro confronts the robot, it is destroyed by the arrival of another inmate with the same powers as Ganta.

Believing him to be the Red Man, Ganta attacks the strange inmate known as Senji Kiyomasa, but falls at a disadvantage against the blades Senji can form with his blood. After learning the nature of his power called the Branch of Sin, Ganta launches a counterattack. Ganta soon realizes that Senji is not the Wretched Egg, but one of several "deadmen" with that power. Senji tries to attack Ganta again, but finds himself weak against Shiro before a special unit appears, tranquilizing Ganta and Senji and taking Shiro and Yō to an empty corridor. As Ganta is examined, he comes face to face with Tamaki who reveals he rigged Ganta's jury verdict to get him sent to Deadman Wonderland before revealing Ganta will face off against Senji in a battle the next day, tempting him with the prospect of coming face to face with the Wretched Egg. As Ganta is tortured with footage of what a "carnival corpse" entails, Makina decides to confront the chief director concerning the mysteries of G-Block.

Makina is halted by Chan and En, bodyguards of the chief director, preventing her from entering his office. Ganta is thrust into his carnival corpse match with Senji and is at a disadvantage as his projectiles use too much blood and cause him to develop anaemia. As he becomes helpless, he recalls memories of Shiro and manages to stand back up, using the environment to get a hit on Senji. After escaping from the corridor, Shiro and Yō head towards G-Block after Yō hears the whereabouts of a woman he is searching for. After Ganta recovers from his victory, he is horrified to find that Senji is forced to have one of his eyes removed as a result of losing. As Yō uses Shiro as a diversion so he can escape on his own, he bears witness to her true destructive ability, as she herself has the Branch of Sin.

As Shiro falls unconscious and is picked up by Chan and En while Yō continues his way to G-Block, Ganta meets a girl named Minatsuki Takami, another deadman who had killed her abusive father. Ganta offers to help Minatsuki escape, but soon learns she is his opponent in the next carnival corpse match. When the match begins, Minatsuki's personality changes completely and attacks with her whip-like Branch of Sin, revealing she had manipulated him into taking an injury prior to the match. However, Yō appears, revealing Minatsuki to be his little sister, saying that he plans to gain enough cast points to buy her freedom before entering the arena. Minatsuki tries to manipulate Yō against Ganta, but he turns on her instead, having learned the truth behind his father's death. Minatsuki captures Yō and uses him as a human shield against Ganta, revealing she has shown hatred ever since her mother left her for dead during the Red Hole incident. Ganta manages to disable one of her whips and free Yō, before knocking her out with a headbutt, winning the match.
