A medium shot from a 3/4 view of a refined lady assassin standing before a rainy window. The woman has a stern expression and a razor-sharp gaze partially hidden behind sleek, dark sunglasses. She is dressed in a white dress shirt with the top buttons undone, paired with loose suspenders and a leather gun holster belt cinched around her waist; she casually holds a handgun in her right hand, her fingers gripping the handle with professional ease. Behind her, a glass window is covered in intricate water droplets that reflect the shimmering, blurred lights of a distant city. The scene is rendered in an anime illustration style with a film noir atmosphere, utilizing dramatic chiaroscuro lighting to create deep shadows and bright highlights, a muted color palette with high contrast, and a moody, suspenseful mood.
