A female shinobi stands with her back to the viewer, glancing over her shoulder. She wears a dark padded outfit adorned with leather and metallic accents, predominantly in black and red hues. Her long black hair flows elegantly down her back, partially obscured by a subtle, intricately designed mask. A sleek katana is poised at her side. The setting is steeped in dark tones and muted colors, amplified by high contrast and minimal lighting, set against a black backdrop. The image is rendered in hyperrealism, capturing the essence of stealth and intrigue in the shadowy world of the shinobi.
