Myu-Un Kim is an orphan, who was brought to the temple of Seong Howorl after being wounded. Suffering from amnesia she received the Name "Myu-Un" ("Myu" being "beauty" and Un being "cloud"). Unlike most of the other children in the temple she refused to lean swordsmanship. Instead she was taught how to quickly run away. She has a light way of walking. She regards Ryu-Sang, another orphan from the temple as "her first friend" and is bitter being treated so coldly by him.
