Iruka No. 2's little sister whose real name is Umino Kurara. She adores her big brother and even lets out strange shrieks in imitation of him even though she is clearly trying too hard, sometimes letting her true girlish side show and reveal just how irresolute and full of holes her inner character setting is. She longs for her big brother's lifestyle and has debuted her look in middle school, but her real character is a secret even to her classmates.
