Rainy Neon Anime Style Girl in an Alley

Create a delicate, anime-style vertical illustration depicting a young woman standing alone in the middle of a narrow alleyway in a Japanese city during a heavy rainstorm at night. The image primarily shows her back, a full-body shot, centered, with her head slightly turned to the left shoulder, revealing one eye and part of her face. She has extremely long, flowing hair.{argument name="hair color" default="Dark purple hair with blue and magenta highlights"} Her hair was tied in a low side ponytail, long strands fluttering dramatically in the rain. She was wearing a smart outfit.{argument name="coat color" default="White"} A long, belted trench coat with black piping, shoulder seams, sleeve straps, a back belt, and a small circular armband, paired with black trousers and glossy black knee-high platform boots. The background is a damp, neon-lit alleyway in Tokyo at night, with shops on both sides. The right side has warm window lighting, while the left side is darker, featuring nine clearly visible, vertically illuminated signs in cyan, pink, yellow, and white with stylized Japanese characters; the text can be decorative and doesn't need to be fully legible. Rain falls in long, vertical streaks, covering the pavement, reflecting vibrant neon lights in blue, cyan, pink, and white. A few blurred silhouettes of pedestrians are added to the background to add depth, but the woman remains the absolute focus. The composition employs cinematic framing, a low, level perspective, strong rim lighting, highly saturated cyberpunk tones, clean lines, delicate anime-style rendering, bright reflections, soft depth of field in the distance, and a melancholic, romantic rainy night atmosphere. No watermark, no border, and no other figures in the foreground.
