She is rather petite, has long milk blonde hair, parted in the middle and half wrapped in two buns with green ribbons. Ha-Hyeon dons a modernized Korean garment with a short flowy skirt and flats.
Caring towards her family, especially Yu-Ha. At the start Ha-Hyeon seems very attracted to Hong-Ryung, but in the later chapters it seems that she actually resents Hong-Ryung (reasons yet unknown).
However, she shows care for her group, even while resenting Hong-Ryung, as she instinctively protects (that guard) from Baek-Yong.
Known as high priestess. Ha-Hyeon is apparently very spiritually strong, as she is able to create false bodies and is taught by Ga-Bi. She is seen as powerful in Baek-Yong eye's too as he seeks her help in capturing Ga-bi (her reasons for helping yet unknown).
Her acting skills are superb too, as she fools the whole group that she is on their side the whole journey.
She hates Hong-Ryung to the extent that she wished to kill him the first time they met. She seems to resent Hong-Ryung for possessing a lot of the power that once belonged to Ga-Bi.
She met Ga-Bi when she was very young in a Dae-Hyun village during the time when she faked her death to avoid suspicion in Myung-Joo.
Yu-Ha cares very deeply for Ha-Hyeon, calling her family (unni) and looking everywhere for her. Ha-Hyeon also seems to care for her as well as she was visibly upset (unlike her usual wooden plank expression) when she thought she hurt Yu-Ha.
