A skilled female assassin ninja, clad in a sleek red and black outfit, moves stealthily through a futuristic urban landscape under the cover of night. The cityscape, composed of towering black and red structures, is illuminated by vibrant fluorescent lights that cut through the darkness. The sky is an intense red, with tumultuous red clouds swirling ominously around a crimson moon, casting an eerie glow over the scene. Rain falls steadily, creating a shimmering effect as it reflects the myriad lights of the cyberpunk world. This dynamic and vivid environment, infused with anime-inspired artistry, melds traditional stealth with a high-tech, dystopian atmosphere, embodying a powerful blend of ancient skills and futuristic innovation.
