A female ninja stands atop a rooftop in the middle of the night

A female ninja stands atop a rooftop in the middle of the night, with a bright full moon shining in the dark sky. Her long black hair flows in the wind, and her sharp red eyes gaze intensely at the city below. She wears a sleek, tight black ninja outfit, complete with a mask that covers part of her face. In her hands, she holds two gleaming katanas that reflect the moonlight. The atmosphere around her is mysterious, with a thin mist surrounding the rooftop, giving the impression that she is ready to strike at any moment.
