Night, a vibrant futuristic citys

Night, a vibrant futuristic cityscape filled with neon lights, a cat girl standing on a rooftop, holding a light blue long energy sword horizontally across her chest, striking a cool pose, aggressive standing posture, long ponytail hairstyle, hair transitioning from black to blue, black cat ears with white fur inside, bright blue eyes like gems, slit pupils, cold expression, light blue laboratory-style glasses made entirely of translucent synthetic resin, large breasts, high-tech black combat suit, handgun hanging at the waist, black cat tail. Clean linework. Colors are gentle, skin tones smooth and glossy, with expressive eyes.
