anime, A digital illustration of a young woman with short black hair and green eyes, wearing a futuristic, white and grey suit with the number 55 on it, standing confidently in the center of the image. She has a serious expression and is holding a gun in her right hand. Behind her, a group of zombie-like figures with glowing red eyes surround her, set against a red, apocalyptic background. The style is dark and gritty, with a sci-fi aesthetic. The woman is the main subject, positioned in the foreground, with the zombies looming in the background.
