A medium shot, 3/4 view captures a mysterious butterfly-themed girl standing in a serene, ethereal void. She has waist-length, straight pastel-blue hair that curls softly at the ends, with bangs lightly covering one eye and adorned with butterfly hairpins and a butterfly accessory. Her slender, almond-shaped eyes are a transparent pale blue-purple, reflecting a calm, expressionless gaze. She wears a white T-shirt with a small butterfly print under an oversized pastel-blue hooded parka featuring tulle edges, butterfly wing embroidery on the sleeves, white lace cuffs, a butterfly patch, and a transparent butterfly zipper charm. Her outfit is completed with white short pants accented by light blue lace and a silver belt with a butterfly buckle, white thigh-high socks with blue ribbons, and white-and-blue platform boots with transparent soles. She holds one hand in her pocket while extending the other forward, where a tiny butterfly rests on her fingertip. Large translucent butterfly wings sprout from her back, fluttering softly. The atmosphere is silent and fantastical, bathed in a pale, luminous light with a palette of pastel blue,white, and hints of purple, evoking a sense of crystalline transparency.
