A female shinobi glances over her shoulder, captured from behind, her face partially obscured by a mask, with flowing long black hair. She wields a glistening katana, her dark padded outfit detailed with leather and metallic accents, emphasizing shades of black and red. The ambiance is moody, drenched in dark tones and subtle muted colors. The scene is rendered in hyperrealism against a pitch-black backdrop, with minimal lighting casting dramatic contours, maintaining a mystical yet intense presence while ensuring high-quality depiction and precise anatomy throughout.
