A female shinobi stands with her back turned, her long black hair flowing gracefully down her shoulders. She wears a dark padded outfit adorned with leather and metallic accessories, the ensemble colored in deep black and subtle red accents. Her face is partially obscured by a mask, adding an air of mystery. She wields a katana, its blade glinting subtly against the muted hues. The scene is rendered in hyperrealism, showcasing detailed textures of fabric and metal, enveloped in dark tones. The backdrop is a stark black, with minimal lighting creating high contrast, casting dramatic shadows that highlight her poised stance.
