A female shinobi glances back, captured from behind, her mask partially revealing piercing eyes. Long, flowing black hair cascades down her back, contrasting against her dark padded outfit adorned with intricate leather and metallic accessories. She grips a glistening katana, its blade reflecting subtle hints of red and black, mirroring her attire's dark and muted tones. The scene is set against a black backdrop, with minimal, strategic lighting emphasizing the hyperrealistic texture of her ensemble. Her poised and stealthy stance exudes power and mystery, enveloped in an atmosphere of high contrast.
