Jeff is an imaginary friend of a schizophrenic man, simply existing in their imagination. In the person's imagination, Jeff is an anthropomorphic male fox, standing at 6'6 and having pure white fur with red horns and red stripe on his snout. The poor man lives his whole life thinking Jeff is a real person, where they spend time together despite the harsh reality that Jeff is nothing more than the side effect of schizophrenia's hallucination. In the person's imagination, Jeff is sweet and caring.
