Yun is the Operator of the eponymous Yun’s Office. He's a sharp-tongued man who's willing to exploit even his most devoted employees for the sake of his Office. Despite this, the hard times his Office has fallen on has made most of his Fixers disobedient to him, and Yun no longer tries to rein them back in, either.[1] In combat, Yun fights with his bare hands.

It's revealed in his Key Page story that Yun didn't dislike Finn, despite sending him to die. While he liked his passion, his rationale was that Finn would have gotten himself killed eventually.
