Yoshinoya Umenouchi

About

She is the daughter of a former subordinate family of the Umenouchi clan and is the fiancée of Matsunouchi Michihito.
A bold and proactive woman, she urged Michiruhito to have a child with her when they first met. However, she had almost no love for him and would call him a "monster" behind his back, and saw the marriage proposal as an opportunity for her, an unattractive member of the family, to rise to become the mother of the head of the family, the retired empress (the mother of Ginko). Michiruhito, who had never had a good impression of her to begin with, found out all about her and was killed by a swindler along with Takenouchi Shirakiya during a celebratory parade.
