koshimizu sachiko/輿水幸子

koshimizu_sachiko, from The Idolmaster Cinderella Girls, is depicted from a top-down view lying on her back inside a rectangular, clear vinyl pool filled with water and numerous small ice cubes. The pool is large enough to fit her entire body, and she is fully submerged, with her light purple short hair, featuring hair flaps and a small hair ornament, floating around her head in the water. Her brown eyes are closed, and her face conveys a blissful, relaxed expression. She is wearing a vibrant, patterned high-cut bikini top and bottoms, and her small breasts are visible. Her arms are spread out to the sides, resting on the pool's edge, with her hands open and relaxed. The style of the image is detailed and vivid, with clear, crisp lighting that highlights the translucency of the water, the glistening ice cubes, and the character's serene state.
