Daniel 'Dan' Ding is Bill Ding's nephew. He is from a small fishing village called Tien Sa in Danang, Vietnam. Though he is from Vietnam he has no accent and does not speak Vietnamese.
He became aware of Bill's disappearance after his mother started receiving threatening messages from the taxi company which employed him. They claimed that Bill had never returned one of their cabs and they would sue her for every dime she is worth if not reimbursed for it's value.
He is an Olympic level competitor in 50m free pistol shooting with a 22 calibre pistol. When he is not getting money from competitions and sponsorships he acts a a close quarter combat instructor for room clearing and quick draw pistol shooting for a small Vietnamese mercenary group called The Red Snakes.
Daniel is a very shy young man with Tourette Syndrome character traits, one of which involves a clicking noise he makes when nervous. These traits are not for the sake of humor; they are part of Daniel's mannerisms.
