Just for some context for those who didn't know (I don't really remember all the details so forgive me if I made a mistake):
Kiyohime used to be in love with a monk named Anchin, but he lied to her and left her. Because of this, when summoned, she considered her Master as an incarnation of Anchin and is yandere towards her Master. She also really hates being lied to, and won't hesitate to kill her Mastee if they lied to her. Other than that, she's apparently a pretty good housewife.
