Undertakers

The Undertakers were a task force created by Tsunenaga Tamaki that consist of the worst prisoners Deadman Wonderland has to offer. They carry technology called Worm Eater which nullifies a Deadman's Branch of Sin.

History
Sometime in the past, when Azuma Genkaku killed Nagi Kengamine's wife along with his unborn daughter, Nagi lost his sanity and brutally and mercilessly killed 22 undertakers while Genkaku hid in a locker to escape Nagi's wrath.

A few years later, the Undertakers try to stop Scar Chain from escaping Deadman Wonderland. Hibana Daida, an Undertaker cuts Nagi's arm off, but Nagi knocks her out cold, activates the elevator, then is captured by the Undertakers. While Scar Chain are using the elevator, the Undertakers ambush them, killing some of them. After that the Undertakers have to leave as Mozuri Gazuchi told Genkaku.

The Undertakers later enter Scar Chain's room, along with Rokuro Bundo, attempting to kill them. Ganta is firstly chosen by Rokuro, however, before Mozuri and his partner in crime Shinagawa Dokoku can kill Ganta, Kiyomasa Senji kills them, then Senji and Scar Chain fight the Undertakers of.

After some of the Undertakers are defeated, the Undertakers capture and attempt to rape Shiro and Karako Koshio, of which a video is shown to Scar Chain. After that Scar Chain fight the Undertakers and Ganta arrives to save Shiro and Karako, killing some of the Undertakers. However, a now insane Nagi is revealed by Genkaku, who starts killing the Undertakers. However, when Nagi hears Karako's bell around her neck, he regains his sanity. Seeing this, Genkaku stabs Karako, hoping Nagi will become insane again, but it does not work, causing Genkaku to kill Nagi then the rest of the Undertakers. Hibana is killed by Rinichiro Hagire in Toto Sakimagi's body and Ganta uses his Ganbare Gun on Genkaku who attempts to escape it but Nagi stops him, saying that he is his guide to Hell, resulting in both of them getting hit by it.
