character: mr._c.b._(umamusume), A medium shot from a rear view, captured at a slight angle, featuring Mr. C.B. sitting on the edge of a luxurious bed in a dark, shadowy bedroom. She is glancing back over her shoulder toward the viewer with a soft, mysterious, and gentle smile. Her upper body is exposed, showcasing an extremely hyper-muscular physique with massively oversized lats spreading wide like wings, deeply carved spinal erectors, and hyper-developed trapezius and rear delts that create an exaggerated V-taper silhouette, with prominent veins visible across the muscle fibers. She has very long brown hair flowing over her massive back muscles, adorned with a mini top hat, accompanied by horse ears and a horse tail. The room is shrouded in deep shadows, illuminated only by pale, cool silver-blue moonbeams streaming through sheer curtains, which highlight the definition of her exaggerated muscles. The atmosphere is melancholic and elegant, utilizing a high-contrast color palette of deep blacks and lunar blues to emphasize a hyper-muscular bodybuilding aesthetic in a high-quality anime illustration style.
