A female assassin dressed in a sleek red and black ninja outfit moves stealthily through a neon-lit, cyberpunk cityscape under the veil of night. The surroundings feature towering black and red buildings that rise into a dark, foggy sky, tinged with fluorescent lights casting vibrant hues across the scene. The red sky and swirling red clouds create an ominous backdrop, while a crimson moon hangs eerily above. The atmosphere is charged with tension as rain begins to fall, adding a dynamic essence to the environment. Her swift movements and piercing gaze, reminiscent of anime artistry, blend seamlessly into this hybrid world of technology and ancient stealth.
