Toto Sakigami

A mysterious Deadman feared even by Senji, Toto is a mysterious boy dressed in a way reminiscent of Shiro, and appears not only to be one of the strongest Deadmen introduced so far, but also to know in great detail about the true nature and purpose of Deadman Wonderland.

His Branch of Sin, Love Labyrinth, allows him to copy the abilities of other Deadmen. However, he states that he recently was reset of his copied powers after his battle with the Red Man. However, even in his weakened state, he managed to take down two of the Forgeries with nothing but a copy of Crow's powers. Nicknamed Mockingbird, he freely comes and goes through the prison, and recently has become friends with Ganta. Toto is the only person to have fought the Red Man and have survived.
