A fierce female samurai with long

A fierce female samurai with long black hair tied back, gripping a naginata in a battle-ready pose. She wears ornate dark red and black lacquered armor with gold accents, a mempo mask pushed up to reveal her stern face. She stands in the courtyard of a Japanese castle, rain falling around her, the stone wet and glistening. Her eyes are intense and focused. Dramatic lighting with storm clouds overhead, atmosphere tense and charged before combat.
