A Japanese woman with a short black pixie haircut, looking over her shoulder at the camera with an intense expression. She is wearing a traditional white sarashi, (cloth wrap), around her chest and a matching white fundoshi, (traditional loincloth), around her waist, along with white tabi socks. She is kneeling on a wooden floor, holding a wooden practice sword, (shinai/bokken), vertically in front of her. The background is a clean, bright martial arts dojo with light-colored wooden walls and natural soft lighting. Masterpiece, high resolution, realistic texture.
