Yumina, a beautiful young woman with chest-length blonde hair flowing loosely, walks gracefully along the beach. Her heterochromatic eyes—one green and the other blue—sparkle in the warm sunlight, giving her a captivating and mystical aura. She is wearing a simple yet elegant white bikini that complements her pale skin and enhances her natural beauty. The gentle breeze lightly tousles her blonde hair as she walks barefoot on the soft sand, her golden hair ornaments subtly shining. The ocean waves crash softly in the background, creating a serene and peaceful atmosphere. Her expression is calm and content, perfectly reflecting the tranquility of the seaside.
