Renka is a fair-skinned young girl of average size. She has bright blue eyes with upper-back-length purple hair constantly done up in an intricate braiding; it has two seperate strands on each side of her head and one in the back (similar to cat ears and a tail), and and chin-length bangs hanging over her eyes with sideburns looping up her jaw. Similar to Miu, she sports a noticeably curvaceous frame and large bust.
Renka tends to wear revealing chinese dresses, even at times appearing rather skimpy, that draw attention to her breasts and legs. They even tend to be rather skimpy, suggesting she doesn't have much modesty. She also wears a golden bell behind each ear. When in school outfit with stockings.
