Ou Kijin is Dakki's younger sister. She wields the Shijuhagoromo, a protective paopei capable of releasing poisonous moth dust. Her resentment towards Taikoubou stems from her initial defeat and humiliation at his hands, which exposed her true form as a stone lute.
On Hourai Island, Ou Kijin received a power-up from Jouka. Consequently, her Shijuhagoromo's defensive capabilities became significantly stronger. Additionally, she acquired the ability to control lute strings that can sever anything.
