Deadman mass prison break

The Deadman mass prison break was an operation set up by Scar Chain. It's goal was to expose the secrets of Deadman Wonderland to the outside world. These are the existence of Deadmen and the Carnival Corpses. This was supposed to lead to the shutdown of DW and the release of the Deadmen. The operation was a failure because DW still operated afterwards, but was also a success because several Scar Chain members eventually escaped.

Early stages
In prospect of the prison break, Scar Chain made an agreement with an infiltrator in the DW inspection team. He will distract Tsunenaga Tamaki. Rokuro, the chief of intelligence, also made a data chip that contains all the information about DW that is needed to shut the prison down. That is the evidence that Deadmen exist and the many illegal acts Tamaki commits. That disk will be handed over to the inspection team and he will expose it to the world.

Prison break
The actual operation started in the week of the annual DW inspection. Then, there will be less guards and the show will be put on hold (including the Carnival Corpse). Before the actual operation itself, they activated emergency alarms in several positions, causing major confusion. Then, Scar Chain will begin to move into two groups (Karako, Ganta and the other Scar Chain members and Nagi and Rokuro).

Karako and her group move towards an elevator that can bring them in safety and where they will hand the data chip to the inspection team. To get to the elevator, they managed had to go through a restricted area. They managed to get access, but were unable to prevent the coming of a Necro Macro. The group was threatened to be killed, but Karako sacrificed herself by fighting the Necro Macro alone. She handed the chip over to Ganta. Karako won, but fell from the hanger and was unable to go through. Ganta's group eventually got to the elevator, that wasn't moving yet.

Meanwhile, Nagi and Rokuro broke in the control room and defeated the guards by using their Branch of Sin. The goal of this action was to activate the elevator, that would bring the other group in safety. As Nagi was about to activate it, Hibana Daida showed up and attacked him. She cancelled Nagi's Branch of Sin with her Worm Eater and explains why. It's then that Nagi realizes that Rokuro manipulated the footage of Ganta attacking Genkaku. Rokuro reveals himself to be an the Undertaker's side. During the fight between Nagi and Hibana, Nagi was able to defeat Hibana and punch Rokuro. He then activated the elevator.



The remaining Scar Chain members then got on the elevator, making small talk on the way. They arrived at a storage area, but are awaited by the Undertakers, led by Genkaku, who immediately starts firing. Fujiyoshi and another unnamed member are hit and die. Some members summon their Branch of Sin, but they are all cancelled by the Undertakers' Worm Eater. Miya is beheaded and Kazu flees into a room, but is burned to death. The Undertakers clash with Scar Chain.

Meanwhile, Nagi has collapsed and Rokuro talks to Nagi saying that the Undertakers are after the others too and that they only have a 1,2% chance of survival. Nagi says that's enough and still believes in the success of the operation. However, Rokuro explains that it's his job to make those chances zero, and implies that the data chip is actually a bomb. When Rokuro isn't looking, Nagi takes out his radio transmitter and contacts Scar Chain's base's computer. There, Shiro hears Nagi's voice who says that the data chip is a bomb and that somebody has to prevent it to kill the other Scar Chain members. Shiro leaves and searches for Ganta and the rest.

Back to Scar Chain, is almost everybody killed, except for Ganta and some other unnamed members. When Genkaku is about to kill Ganta, Mōzuri comes up and tells him it's time to retreat. Scar Chain regroups and gets ready to escape, but Shiro suddenly appears, takes Ganta's data chip and throws it in the fire, where it violently explodes.

Aftermath
Scar Chain had no choice to retreat after that, and they gathered back in Scar Chain's headquarters. There, they met up with Karako again. They pitied themselves and wanted to give up, but Karako pursued them to go on with the plan.

Confrontation:
Ganta confronts Shiro after when she threw the data chip into the fire. It is later revealed that this was a bomb
