Riruka is a young, slender girl with magenta eyes and long hair of matching color, styled into two pigtails, and between which she wears a light-colored hat that has two extensions in the back, made to look like rabbit's ears.

A strand of hair hangs down the right side of her face and she has a fringe over her forehead. She also wears a dark dress with white fabric over her breasts with a dark ribbon just above it. She completes her outfit with a pair of thigh-length boots.
