A fierce female samurai warrior standing confidently against a deep black background. She wears dark leather armor with red accents, a katana on her back, and a red tattoo on her shoulder. Her hair is tied in a messy bun with loose strands framing her intense expression. Subtle lighting highlights her silhouette and armor textures. The style is cinematic, painterly, and highly detailed with a moody, dramatic tone. Japanese kanji in glowing red appear subtly behind her. Concept art, digital painting style.
