Shiro is a small, fluffy, white dog, that wears a red and white corded rope around his neck like a collar. He looks similar to the Japanese Spitz, who are known for their loyalty, affection, devotion and great courage. The rope makes a large tie across his back.
Shiro is a very energetic dog, who trusts and believes in his friends. He is completely devoted to his new job in Animal Hell, and enjoys viciously attacking, biting and mauling the damned. He has a tendency to accidentally blurt out rude statements and is easily excited by new things, much like a child.
