Tsunenaga Tamaki

Tsunenaga Tamaki is the Assistant Warden and de facto tyrant of Deadman Wonderland, serving as a major antagonist in the story's first half. Behind a calm, almost foolish manner, he treats prisoners as expendable subjects for profit, experimentation, and amusement. He devotes extensive resources to researching the Branch of Sin and seeks to create artificial Deadmen, while incongruously enjoying children's toys.
