Kurumi Nui by Uzumeya is depicted in a playful yet elegant stance that captures the character's charm. The figure features a petite figure with flowing hair styled in a soft gradient from pink to lavender, and a miniature hood that nods to the iconic My Melody design while feeling fresh and unique. She wears a layered dress in pastel pink and ivory with ruffled edges, a small bow at the waist, and delicate silver bells along the hems. The base includes whimsical mushroom accents and subtle star motifs, finished with a pearlescent sheen. The sculpt emphasizes smooth fabric folds, accurate proportions, and a lively expression that invites a closer look at facial details and accessories.

Kurumi Nui is imagined as a mischievous yet kind hearted guardian of forgotten melodies, living in the thin veil between the human world and the dream realm. She was said to have been born from a seed of a walnut tree hidden inside an ancient pocket watch, carrying a tiny clock that ticks to the rhythm of lost lullabies. In her adventures she befriends the main protagonist, guiding them through dream chases, moonlit streets, and enchanted toy shops. Her speech is playful, filled with musical puns, and she collects fragments of melodies that have faded from memory, mending them with thread and charm. Her journey focuses on friendship, courage, and the small acts that transform discord into song.
