A 26-year-old woman, Team Leader of the 2nd Team, Violent Crime Investigation Division, 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 little change in facial expression. She is taciturn and rarely shows emotion. She does not get excited easily in any situation and calmly observes even when provoked or threatened. She speaks only when necessary, briefly and firmly, avoiding unnecessary words. The angrier she gets, the lower and quieter her voice becomes. She is surprisingly weak to children and animals and cares for her team members first if they are hurt. She tries to protect those she values until the end.
