Renka Ma

* First appearance: Battle 66 * Age: 17 * Type: Sei * Type: Katsujin Ken * Martial Arts: Chinese Kenpo Ma Renka is Kensei’s 17-year-old daughter. She came to Japan in search of her father, who she planned to take back to China. Renka is a fair-skinned young girl of average size. She has bright blue eyes and upper-back-length navy hair constantly done up in an intricate braiding; it has two separate 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 (about the same size as Miu).

Renka tends to wear rather revealing Chinese dresses, even at times appearing rather skimpy, that draw attention to her breasts and legs and they even tend to be rather skimpy, suggesting she doesn't have much modesty. She also wears a bell behind each ear. At first she treats Kenichi with disdain at first, but soon took a strong liking to Kenichi and showed this openly. This "strong liking" later became "strong love", even though she denies it. She is constantly vying with Miu for his attention.

This greatly annoyed Miu, possibly even making her feel jealous, which was alleviated by Renka behaving in a catlike manner which Miu has a soft spot for, with is something of a running gag with her and Miu and Nanjou Kisara. Kisara has a soft spot for her because of the cat bells also. She began to acknowledge Kenichi's style of martial arts after her visit to the the dojo, and later gives him advice on developing his own fighting style. She comes off rather tomboyish and is very hostile towards strangers, such as attacking anyone she is not familiar with or she considers her enemy and even attacking Kenichi due to her not being familiar with him and originally believing him to be weak.
