Tsunenaga Tamaki

Tsunenaga Tamaki is a major antagonist, the Assistant Warden and de facto tyrant of Deadman Wonderland.

Under his calm, almost idiotic attitude, he is something of a sadist, caring nothing about the fact that he butchers dozens of prisoners every day for the sole purpose of gathering money or experimenting on them, or simply, and mainly, for his own twisted amusement. As son of the dying Chief Warden of Deadman Wonderland, he eagerly hopes for the death of his father to become truly the supreme ruler of the prison, and he devotes much of his time and resources in studying and experimenting on the powers of the Branch of Sin and their origin. He also is in contact with the upper echelons of the Japanese government, his ultimate goal being the synthesis of artificial Deadmen]. In sharp contrast with his cruelty, he enjoys playing with children's toys. It is later revealed that his sick game was really just part of his plan to kill the [[Wretched Egg. Through his research he has created a being that, according to him, will soon hunt down and kill all beings with Deadman powers, including the Wretched Egg, for nutrition. Before the Great Tokyo Earthquake, Tamaki was a reclusive and indifferent computer otaku who spent hours if not days secluded in his room, playing games, not caring anything even about his own family. The massive earthquake, which destroyed his home and games, sent him over the edge of sanity and led him to engineer Deadman Wonderland as a gigantic game, so as to keep playing as he did before the earthquake. Nevertheless, when confronted by Toto, who revealed himself to be the real Director of Deadman Wonderland, and made aware that he himself was no more than another pawn in his own game, Tamaki shot himself in the head as an ultimate assurance that this was his, and only his, game.
