Yō Takami

Yō Tamaki is a prisoner at Deadman Wonderland. He is the older brother of Minatsuki Takami.

Personality
Though apparently polite and friendly, he is actually ruthless, scheming and somewhat paranoid due to his position as a spy. He is also a kleptomaniac. He lies just as much as his sister, but he still cares a lot for her.

History
After the earthquake in Tokyo, Yō decided to protect his sister in place of his mother whom had died. Because of this urge to protect her, Yō had become gullible to her lies like the one about her father abusing her and led him to originally believe that he had killed his father instead of her. However, Minatsuki was still sentence to death at Deadman Wonderland for the murder. Yō, believing that Minatsuki was incapable of killing and therefore innocent, willingly went to Deadman Wonderland in search of her.

Prison arc
Yō first appeared when bumping into Ganta Igarashi and discreetly stealing his Candy.Makina, the warden, saw this and punished him accordingly, by slashing him across his chest. He was taken to the infirmary afterwards. He meets up with Ganta again in the hospital, when Ganta was injured after "the accident". They talked a little until Shiro appeared from the ceiling, which surprised Yō. Yō explained the working of DW and the Dog race, after which Ganta and Shiro decide to join, for the sake of sweet beans.

In the anime, Yō joins too, but was attacked by Kōzuji Kazumasa and couldn't enter anymore. In the manga, it was Azami who was attacked Yō stays out from the beginning. Either way, Yō still watches the race and takes bets. When a prisoner came up to Yō and told him he couldn't give him Yō's money, Yō ripped out his earring as compensation, showing his true nature for a short time.

After the race, Yō sees Ganta again when he finds out he in the same cell. He introduces himself and gives Ganta Candy, saving his life. This was all part of a plan to get in favor with him, for he was spying on Ganta on command of the promoter. He hangs out with Ganta in the prison yard later. They were eating icecream when the Red Man suddenly appeared. He started destroying the garden, killing many prisoners in the process. Yō was frozen with fear, seeing how Ganta developed a similar power of his own. He thought that Ganta was a freak like the Red Man and thought that Tamaki wasn't paying him enough for this.

Deadman arc
During the Carnival Corpse match between Ganta and Minatuski, Yō sneeks into the arena dressed as a guard and immediately comes to the defence of his sister. Further on, he realizes that his sister is not as innocent and he percieved her to be and questions her about the death of their father. Despite knowing the truth, he still defends his sister even when he attacks him. Eventually, Minastuki and Yō form a estranged sibling bond.
