Renka has brown hair in a twin-tails with a cowlick in the shape of a lightning bolt. She is a very energetic girl that dislike effeminate and cutesy things and, if there’s a commotion somewhere, is prone to butting in and raising her own brand of hell. No matter how tense a situation gets, though, she has a sense of humor about her and uses her laughter to break across to the other side.
