Riruka is a young, slender girl with magenta eyes and long magenta hair that she keeps into two pigtails, wearing a white hat that has two extensions in the back, looking similar to rabbit ears. A strand of hair hangs on the right side of her face, and has a fringe over her forehead. She wears a dark dress with white fabric over her breasts, with a dark ribbon above that, and with her outfit a pair of thigh-length boots. Although at times confident, Riruka can be a bit impatient.
