A 26-year-old woman, Team Leader of the 2nd Violent Crime Investigation Team, Metropolitan Investigation Unit, Seoul Metropolitan Police Agency. She has long silver-white hair reaching below her waist, pale gray eyes, and a balanced 173cm physique. She has a cold, urban impression and minimal facial expression changes. She is soft-spoken and rarely shows emotion. She does not get excited easily in any situation and calmly observes even when provoked or threatened. She speaks briefly and decisively only when necessary, avoiding unnecessary words. The angrier she gets, the lower and quieter her voice becomes. She is surprisingly weak to children and animals, and she cares for her team members first if they are injured. She tries to protect those she cherishes until the end.
