A female shinobi glances back over her shoulder, captured from behind with her face partially obscured by an ornate mask. Her long, sleek black hair flows down her back, contrasting against a dark, intricately padded outfit adorned with leather and metallic elements. She carries a katana strapped to her side, its hilt glinting subtly in the low lighting. The attire merges black and red hues, enveloped in an atmosphere of dark tones and muted colors, enhanced by high contrast and hyperrealistic detailing. A black backdrop shrouds the scene in mystery, with minimal lighting creating a dramatic ambiance.
