Ha-Hyeon (adoptive sister)
Yu-Ha is the daughter of Ga-Bi and the previous King of Myung-Joo, as well the younger sister of Hong-Ryung.
She has shoulder length blonde hair, and blue-grey eyes like her mother. She strongly resembles a younger version of Ga-Bi.
When Ga-Bi left her husband and son in order to protect them, she had been unaware that she was pregnant with her second child. During this time, she had taken in a girl with strong spiritual powers like herself, whom Ga-Bi called Ha-Hyeon. When Ga-Bi realized that she was pregnant, she was distressed that she had taken her husband's child away but could not return to him. After she gave birth, she and Ha-Hyeon named the baby girl, Yu-Ha. Yu-Ha came to see Ha-Hyeon as an older sister, and the three of them lived together peacefully.
