Sidoh is the Shinigami whose Death Note is stolen by Ryuk. By the time he realizes this, however, the note has already changed hands several times, ending up in the hands of the Mafia. Sidoh wears heavy clothing that obscures most of his features, and his head is wrapped in bandages. His mouth is a canary's beak. Obata states that Sidoh's "arms" can be described as insect-like in the way they fold into his body. Though he has "hands," there are only three fingers on each appendage. He has a great liking for chocolate, just like Ryuk does for apples, a taste he shares with Mello. He can be persistent when chasing something he wants, like his notebook.
