A female shinobi stands with her back turned, glancing over her shoulder. Her long black hair cascades down her back, partially obscured by a sleek mask. A sharp katana is strapped to her side, ready for action. She is clad in a dark, padded outfit adorned with intricate leather and metallic accessories, hues of black and red intertwining seamlessly. The scene is enveloped in dark tones and muted colors, enhanced by high contrast and rendered in hyperrealistic detail. The backdrop is pitch black, with minimal lighting casting subtle highlights. This scene maintains a mysterious aura, evoking an air of stealth and mastery.
