Arang (Korean: 아랑) is a figure in the folklore of the Miryang area of Korea.
According to the legend, she was the daughter of a magistrate (busa) of Miryang during the Joseon Dynasty.
Her father, thinking she had eloped with a stranger, resigned his position in shame.
Thereafter, whenever a new magistrate was appointed Arang's spirit would appear before him to seek his help in getting justice and eventually no one wanted to take the position out of fear.
At last a bold man named Yi Sang-sa was appointed to the post, and he promised Arang's spirit that he would avenge her.
