Incongnito

Jeremy, the son of a criminal and a trained cadet got caught up in a hell of a mess after meeting an unorthodox fox in his backyard. Now, he is almost identityless and is forced to battle with his bare claws. The burden only gets heavier as he goes on, turning him into something that truly has never been seen.
