メリュジーヌ holding ruler

character: melusine_(swimsuit_ruler)_(first_ascension)_(fate), A wide shot, full body framing of Melusine in an underground parking garage, positioned centrally but small in scale to emphasize the vast, concrete environment. Melusine, a young girl with long white hair in a high ponytail, sidelocks, yellow eyes, and forked eyebrows, smiles with half-closed eyes. Melusine wears a skin-tight black cycling uniform consisting of a bodysuit and bike shorts that cover her nipples, navel, and groin, complementing her modern loli anime style with rounded proportions and an oversized head. She holds a ruler vertically with both hands, placing it from her groin to her abdomen, measuring her body. Dark dragon wings and a tail extend from her back, adding texture to her silhouette. The background features concrete pillars, dim overhead lighting, and parked cars, creating a cool, industrial atmosphere. The image employs a modern loli anime style with rounded proportions and oversized heads, rendered in high-quality anime illustration with sharp details and a playful, cute aesthetic.
