character: Zerø (oc), A medium shot, eye-level illustration features Zerø, an angel girl with a petite, flat-chested build, standing centrally. She has a joyful expression with a cute smile and round, sky-blue eyes beneath thick, small eyebrows. Her very long, straight pure white hair is styled with cropped bangs and a large ahoge, featuring sky-blue colored inner hair and streaks in her bangs. She wears a white and blue robe, and a light blue halo floats above her head while large white angel wings extend from her back. Zerø is holding a gift box with both hands, presenting it forward. In the background, a birthday cake sits on a surface, accompanied by the text "happy birthday." The scene is rendered in an anime illustration with a painterly style, characterized by sketchy linework, soft blended shading, and dramatic, high-contrast lighting that creates deep shadows and bright highlights.
