Crab in Orange became a Food Soul during the Southern Song Dynasty. He's obsessed with mechanisms and machinery, and the bronze crab he rides is named 'Unnatural.' Not only is it his work, but it's also his trusted friend and assistant. After a deadly accident, the Micians (an unethical organization), saved his life by replacing nearly every part of his body with machinery. Because of this, he lost his memory and humanity. He doesn't have a heart, but is kept alive by his spiritual essence.
