Chang Sik

Chang Sik is a Red Dragon that became Judge O's Charyeok. It was not until later in the series that she was revealed to be female as well as a polymorph like Jang Ho-Sik. Due to the time she spent as his Charyeok, Chang Sik is close to Judge O and protective of him, and vice versa. She loves gold, and can be seen almost crying after doing a job and not being given one.
