character: katsuragi_ace_(umamusume), A medium shot, 3/4 view of Katsuragi Ace, a hyper-muscular athletic girl with horse ears and a tail, posing playfully in a gym locker room. She possesses bodybuilder-level muscle mass across her arms, shoulders, chest, and core, with every muscle striation and vein clearly visible through her tensed physique. She is laughing with a big, bright smile, her right arm raised high in a cheerful thumbs-up gesture while her left hand rests on her hip. She wears white training bandages wrapped tightly around her upper body and tight blue jeans that strain against her powerful thighs. The background consists of a rustic brick wall and gym lockers, illuminated by warm, ambient indoor lighting. The visual style is a high-quality anime illustration with a vibrant color palette, sharp focus on the muscular anatomy, and a lighthearted, energetic atmosphere.
