Age: 18

Gender: Female

Seung-ah has a long brown hair tied into a ponytail. She wears some kind of modified traditional 'dobok', a type of cloth you wear for certain martial arts.

Not much is shown about her personality. She is enraged when she catches the sight of Jegal Taek, because her sister was attacked and crippled by him. She also seems to be close to Il-pyo. Due to Il-pyo taking the blame for breaking a pot when both of them were kids, she has taken a liking into him.

For comic effect, it is shown that she has a soft spot for attractive men, a trait displayed when she quickly had a nosebleed upon Park Il-pyo's transformation, even giving a thumbs up in approval at his new appearance.
