anime illustration, A top-down three-quarter portrait shows Yuki Aoyama lying on her back, body straight with arms at her sides and feet together on a white silk towel, gazing calmly upward with a soft, surrendering expression. She is a 20-year-old Japanese woman with long, slightly wavy light chestnut hair with honey highlights spread loosely around her head, wearing a very small champagne-pink velvet micro bikini. Late-afternoon sunlight casts a warm golden glow across her figure, with turquoise waves and smooth mist-covered boulders in the softly focused background, rendered in a painterly anime style with smooth shading and shallow depth of field.
