Create a vertical 3:4 monochrome anime-style illustration in deep oxblood red ink on a warm cream paper background, like a high-contrast stencil and loose brush sketch. The scene is a romantic old European city street viewed in perspective, with tall narrow medieval buildings on both sides, steep rooftops, pointed towers, clock-tower silhouettes, awnings, shopfronts, and distant pedestrians fading into the bright central street. In the foreground, place a mysterious elegant young woman, {argument name="character name" default="Ouwa Days"}, shown mostly as a dark silhouette from behind and slightly in profile, wearing a very large tilted wide-brim hat decorated with flowers, wavy shoulder-length hair, and a flowing dress or shawl with transparent ribbon-like fabric trailing leftward. Add floral ornamentation on her outfit: exactly 1 flower cluster on the hat and exactly 3 prominent flower clusters on the dress/shawl. Include exactly 2 ornate wall-mounted street lamps, one on the left building and one on the right building. Include small distant human silhouettes in the street, clustered naturally but not detailed. Use dynamic ink splashes, jagged brush edges, sketchy architectural linework, and strong negative space in the sky and street. Keep the palette to only {argument name="ink color" default="dark burgundy red"} and {argument name="paper color" default="warm ivory cream"}. In the bottom-right corner, add a small handwritten signature reading {argument name="signature text" default="ouwa days"} with a small paw-print icon beside it. No additional colors, no photorealism, no modern objects, no border.
