Wakaba Mutsumi, from bang dream, long straight green hair falling straight down her back, sharp yellow eyes, and a calm, slightly melancholic expression. Full body view, entire figure visible from head to toe. She is standing straight, facing the viewer. Pure solid white background, soft bright lighting. She is wearing a dark navy blue winter sailor uniform. The outfit features a long-sleeved sailor blouse seamlessly connected to a high-waisted pleated skirt, forming one continuous uniform silhouette. The blouse has a white sailor collar and a grey ribbon tie. The skirt has white stripes near the hem. She wears black knee-high socks and brown loafers. Clean anime illustration, crisp edges, high contrast, masterpiece.
