Ou Kijin is Dakki's younger sister and a user of the paopei Shijuhagoromo, a defensive weapon that releases toxic moth dust. She's best known for her bitter rivalry with Taikoubou—it started after he beat her in their initial encounter and forced her to reveal her true form as a stone lute, an experience that clearly left her embarrassed and resentful. Fans often note that this humiliation is what drove much of her antagonism toward him going forward.
