High-Contrast Japanese Beauty Portrait with Katana Pose

A highly detailed image generation prompt designed for the Higgsfield Nano Banana Pro model, specifying a 21:9 aspect ratio. The prompt meticulously defines composition, lighting (strong side-backlighting with hard leaf shadows), subject features (young Japanese woman, K-pop inspired makeup, long black hair), clothing (white bandeau crop top), color system (cool white, gray, deep black), camera angle, image quality, atmosphere, and a specific action pose involving a katana, creating a cold, sharp, and dramatic portrait.
