A mysterious albino girl that Ganta Igarashi encountered during his first days as an inmate. Clothed only in a skin-tight bodysuit and muffly gloves, which conceals her heavily scarred skin, Shiro stands out among the other prisoners due to her bizarre appearance and mannerisms. To Ganta, Shiro's manner of speaking and acting remind him of a small child, even though Shiro is the same age as him. However, Shiro possesses inhuman physical abilities and has an intimate knowledge of the prison, having apparently lived there most of her life. From the beginning of the story it is made clear that, as children, Shiro and Ganta were close friends. Ganta, however, has no memories of his childhood, which greatly saddens and annoys Shiro.
Shiro is a childhood-friend of Ganta and the original Deadman - The Wretched Egg.
Shiro is a bubbly, happy girl that seems to be a klutz. She also has a lot of energy (most likely from the fact she eats nothing but sweets), although her mind cannot understand much. While she doesn't fully understand Deadman Wonderland, she knows how to help Ganta and only wants his happiness- even to the point of killing him when he asked. She is incredibly strong, however dense she is, and uses her strength to help Ganta as much as possible after a childhood incident between them. During the dog race show, she's seemigly oblivious to the dangers of the game and occasionaly gets in the way of Ganta's progression (or survial) only to be later realised by Ganta that she was discreetly taking Ganta's blows for him.
