A nighttime scene set in a vibran

A nighttime scene set in a vibrant, multicolored futuristic city, where a catgirl stands on a rooftop, holding a light blue long laser sword horizontally across her chest in a cool, aggressive standing pose. She has long ponytail hair that gradients from black to blue, black cat ears with white fur inside, and gem-like bright blue eyes with vertical pupils, displaying a cold expression. She wears light blue laboratory-style glasses made of translucent synthetic resin. Her figure features large breasts. She is dressed in high-tech black combat gear with a pistol hanging at her waist and a black cat tail. Clean linework. Colors are gentle, skin tones smooth and glossy, with expressive eyes.
