Setsura is Tsurara's mother. She was part of Nurarihyon's Hyakki Yako and had an unrequited love for him. As a result, she came to dislike his wife Yohime. At the battle with Hagoromo Gitsune, she had a match with Ibaraki Doji 400 years ago.
Later she fell in love with Rihan but never confessed her love for him because she knew how deeply he loved Yamabuki Otome. She instructed her daughter, Tsurara to "take the lips of the 3rd heir".
