A 22-year-old Chinese woman named Tsuwei, a slim 159cm assassin codenamed "Hedgehog," stands in a medium shot from a low angle. She has long black hair in a high ponytail, sharp yellow eyes, a toned slender build with defined abs and thin legs, fair skin, and a cool, stoic expression. She wears a cropped black tank top revealing her midriff and abs, tight black pants tucked into knee-high combat boots, fingerless gloves, and a utility belt with pouches. Her hands rest casually at her sides, fingers slightly curled. She stands confidently in an urban alleyway at night. Neon signs in Chinese and Japanese glow vividly on brick walls, casting colorful reflections on wet pavement littered with puddles and debris. Hyper saturated candy colors dominate with vivid neon accents in hot pink, electric blue, lime green, and cyan. High contrast complementary colors create pop art energy, sharp edges, bold outlines, and dynamic halftone patterns. Dramatic rim lighting silhouettes her form against the glowing backdrop, evoking a tense, vibrant urban atmosphere.
