Shiro

Calls himself a "deity." He's a shinigami that exists solely for the job of taking souls to heaven or to hell. His current appearance is how he was born, and he'll never age or die. He's a little over 200 years old. Humans are unable to see him, and shinigami rarely ever come into contact with their own kind, so their isn't a need for them to have a name. "Shiro" (meaning "white" because his hair is white and his skin is pale) is a name given to him by Ayumi, the only known human to be able to see shinigami.
