One of the descendants of Noah and a follower of the Millennium Earl, Skin is assigned to kill Froi Tiedoll, the General being escorted by Kanda and Marie, who has come to Japan. Skin was first introduced in the early manga when he expressed disgust at the Earl's dinner, preferring sweets over hard-boiled eggs. His anger over the meal led him to destroy the Akuma who prepared it with his bare hands, causing large spikes to grow from his arm and back where his skin had peeled off. Because of this, Tyki always calls him "Sweet Tooth" instead of his real name.
In a flashback, it is revealed that Skin worked at the docks in New Orleans three years before the story began. During this time, he experienced the awakening of the Noah genes, which allowed him to recall the 7000-year-old memories of Noah, causing him immense pain and nightmares. It was then that he vowed never to "forgive it (the Innocence)." The rage of Noah took hold of his body, and he saw the world from the perspective of the Millennium Earl. Along with recovering these memories, he met Road and the Earl, who gave him his first taste of candy to stop him from biting his fingers in pain.
He represents the "hatred" of Noah, and since he comes from New Orleans, it is assumed he is American.
