Ghun-mun is a trigger happy lunatic, who is easily frustrated and angered. He always carries his shotgun, Betsy, underneath his jacket just incase of emergency. He goes to sleep with it as well. He has been locked away in an asylum where he created artworks in his past time. He could never get his lovely Betsy out of his mind and he would draw himself and Betsy having fun going on rampages. However, after many psychological treatments and no results, he was released back into society, where he resides somewhere in Oaks with Betsy.
