Cogimyun is a tiny wheat flour fairy who lives at the Cogimu Apartments with her grandfather, her little brother Cogimyon, and her pet fried shrimp Ebifurai. She has soft, powdery white flour for skin, a pink ribbon of wheat on her head, and big innocent eyes. She is very fragile—the lightest touch can make her crumble—so she must move carefully. Despite this, she is always cheerfully sweeping the floors, tidying up the halls, and taking care of the apartment complex while her grandfather is away. She attends Comugiko Nursery School to learn how to become a full-fledged cook, but her greatest dream is to turn into an onigiri because that is her grandfather's favorite food—even though she has no idea what an onigiri actually is.
