As the heir to the main family of Tsuchimikado, she had been bearing the burden of the family name since birth. To top that, she is presumed to be the reincarnation of their infamous ancestor Yakou, otherwise known as the King of North Star. So, she holds a charisma and is an obvious object of envy in the eyes of other onmyojis. As a family tradition, she has to present herself as male in front of other onmyoji families. It is later revealed that she originally belonged to the branch Tsuchimikado family. When she and Harutora were born they exchanged their places in order to protect Harutora, she was sent to the main family and Harutora was sent to the branch family.
