Lunasa, with short blonde hair and yellow eyes, wears a black vest and frilled skirt, skillfully drawing a bow across her violin. Merlin, featuring long blue-grey hair, wears a hat and frilled attire while blowing into a golden trumpet. Lyrica, with short brown hair, is dressed in a red vest and skirt, energetically playing percussion instruments with her hands. They are surrounded by floating, glowing musical staves and colorful, translucent music notes that swirl around them like ribbons. The background is a dense forest of maple trees with brilliant red and orange foliage, with soft sunlight filtering through the leaves. The atmosphere is magical and harmonious, characterized by a warm color palette and a soft, ethereal glow emanating from the musical symbols.
