Йолда

She bears a strong resemblance to Hilda and carries a mop with her, which she uses as a weapon much as Hilda uses her parasol. The two seem to have an unsettled score and Yolda positively despises Hilda. She is also able to move very quickly and knocks Furuichi and Kunieda out easily. In contrast to Hilda, she has a femme fatale attitude. It is later revealed that she is a dimensional transfer demon like Alaindelon; her powers are said to be even greater than his, and she is able to distort dimensions and create sections of space detached from the physical world. In chapter 129, it is revealed that she is Hilda's sister.

Yolda strongly resembles her sister, Hilda, the only difference is a slight change in costume and keeps her bangs out of her eyes and her hair loose rather then tied. Yolda also carries a mop, while Hilda carries a parasol. Regardless of what she is saying she will commonly speak in a cheerful and playful manner, even if she is issuing death threats or insults. She also seems to be flirtatious, as she attempted to kiss Oga upon first meeting him.
