Neon-hued lights flicker, casting vibrant reflections on rain-soaked streets, while the dynamic color palette dances among the shadows. Above, a crimson sky bleeds into wine-colored clouds that swirl around a ominously glowing red moon. The atmosphere crackles with electric tension, as sheets of rain fall like translucent veils. This cyberpunk world pulses with an anime-inspired fusion of traditional stealth and high-tech intrigue, creating a captivating and enigmatic scene.
