Ganta quickly learns of the very real dangers lurking around every corner in Deadman Wonderland. He soon meets the unusual Shiro, and while defending her from other inmates, discovers a strange new power within himself.

In order to earn "cast points" that he can use to buy antidote for the poison injected by his collar, Ganta goes head to head with one of the prison's toughest inmates in a deadly obstacle course.

Unable to afford antidote, Ganta faces his impending death - until Yoh comes to his rescue. Later, after learning that the Red Man might be an inmate, Ganta, Shiro, and Yoh venture into the secluded G Block to find the truth.

Ganta is locked away in Tamaki's lab after tangling with Senji, who wields powers similar to his own. While quarantined, Ganta learns more about his new abilities - and discovers that he'll soon have to use them in a fight to the death.

When Ganta faces Senji in his first Carnival Corpse, he learns that the effect of using his powers recklessly might be even deadlier than his opponent. Meanwhile, Yoh discovers there is more to Shiro than meets the eye.

Ganta meets Minatsuki, who's locked up for killing her abusive father. When Ganta's efforts to help her escape are thwarted, he's forced to take on Minatsuki in a Carnival Corpse - and the girl shows her cruel true colors.

Ganta meets Karako and Nagi, the leaders of the rebel faction Scar Chain, who help Minatsuki out of a potentially gruesome bind. Unfortunately, Ganta also meets Genkaku, a guitar-toting monk with a real talent for brutal violence.

Ganta decides to join Scar Chain after hearing their plan to expose Deadman Wonderland's darkest secrets. The plot isn't without risks - and there's a chance that the Undertakers are already working to sabotage the operation.

Ganta and his Scar Chain comrades find themselves bloodied after an encounter with Genkaku's crew. Things don't get any better when the battle ends, thanks to a sudden appearance and shocking decision by Shiro.

Ganta lashes out at Shiro for destroying the data chip and the Scar Chain's resolve continues to be tested thanks to a traitorous confession by Rokuro. Things are looking grim for Ganta and his allies - until Senji enters the fight.

Ganta asks Senji to train him to better utilize his powers in battle. Later, after Karako is captured trying to save Nagi, Ganta unleashes his new skills during a rescue attempt - but it might already be too late, thanks to Genkaku.

Ganta, battered in battle and weakened by the poison coursing through his body, tries to use the last of his strength to take out Genkaku - but Shiro might be his only hope.

Set two years after the Red Hole incident and eight years before the start of the series, Senji Kiyomasa is a police officer using his Branch of Sin to fight criminals, but has a little temper. One day, he rescues a boy named Izuru who stole from a gang called Goreless Peace. After returning him to an orphanage, Senji encounters Goreless Peace's chairman, Keigo Ugachi, who also possesses a Branch of Sin. When Senji refuses to join him, he burns down the orphanage and kills everyone in it, including Izuru and the caretaker. Devastated and angered, Senji goes to confront Keigo, gaining some support from his police acquaintances. However, Senji finds himself in a giant spider web formed from Keigo's powers. When Keigo injures Senji's superior Domon, Senji manages to break the sound barrier and break through Keigo's ability, barely holding back enough to not kill him.
