Originally from Hong Kong, he is Naru's calm and taciturn assistant who rarely speaks more than he needs to. He seems to get most of the unpleasant jobs, and works through the night. He appears to be an onmyoji and has a wide range of paranormal skills from exorcism to summoning spirit familiars. Lin says he dislikes Japanese people because of the past conflicts Japan has had with China. At one time, he told this to Mai and she told him that he should forget the past to move on and if he should hate her, it should be because he hates her as an individual. At this, he stated that a long time ago, someone told him the exact same words.
