Assistant warden in Deadman wonderland.
Tamaki Tsunenaga grew up in Tokyo as an isolated young man and a dedicated otaku. He would often spend hours, if not days, locked up in his room where he would play video games for hours on end. For him, it was the perfect life until the Great Tokyo Earthquake hit. When he awoke from the destruction, his primary concern was to see if his video games were in tact before going to get the gasoline generator so he could continue playing despite having a broken arm. Even when he runs into his mother, who was stuck under several pieces of debris, asks for his help, he shrugs her off as he needs to continue playing his games.
However, when the games finally broke down for him, Tamaki lost all parts of his sanity as he grew frustrated with the world. When Deadman Wonderland was put into play to be built as a super prison, he vowed that he would continue to play his sick games for the rest of his life by using the parks resources and the prisoners. Because of this demeanor, he has forged a dark reputation with all the prisoners, staff, and even government officials of Japan who he works exclusively with when it comes to the deadmen in the park. Although, he does not have full access to the park since Hagire Rinichirou is barely alive on life support as Tamaki has taken up the reigns as the de facto owner of Deadman Wonderland.
Tamaki Tsunenga was created by Jinsei Kataoka and Kazuma Kondou, who wrote and drew the manga respectively. The series first began serialization in Kadokawa Shoten Shōnen Ace magazine in July 2007. Tamaki's role in the series is that of one of the major antagonists. His anime counterpart was created by Koichiro Hatsumi and is voiced by Junichi Suwabe. Also, he is voiced by Funimation voice actor, Eric Vale. Tamaki made his first appearance in the first chapter of the manga "Who Killed Cock Robin?" and the first episode of the anime "Death Row".
In the beginning of the series, Tamaki acts like the standard owner of a prison. His demeanor is cold and uncarring but the oddest thing that he shows about himself is how jovial he is with the prisoner's lives. He is often shown in his office playing with toys or watching the brutal events in his prison unfold as opposed to doing something productive in the park he owns. When Ganta Igarashi meets him, he sees just how brutal Tamaki can be when he shows little regard for his life as well as anyone elses. It is here we see just how sadists and cruel Tamaki is. He often makes games out of the way he runs his prison, going so far as to make a spectacle sport out of killing prisoners in an obstacle course and pitting deadmen against one another for Hagire's dark purposes, making it a carnival game.
As time goes on, he develops a far more sinister personality as he allows several issues to go on like the Undertakers versus Scar Chain as well as working with Rei Takashima to create a series of Forgeries to continue his fun. Tamaki tries to keep everything out of Makina's hands as he doesn't want anyone to interfere in his fun. Things begin to crumble though when the Mother Goose system goes offline once more and Makina, the Deadman Wonderland security, and the deadman revolt. He remains collective about everything, stating that the game will continue even though he and Makina fight on the same side. However, when Toto Sakigawa reveals himself to actually be Hagire, Tamaki goes insane as he realizes that he was never in control of his own game as he kills himself.
