Black-haired woman in functional skirt holding a katana kneeling
Black short hair with drooping eyes, wearing a black functional style skirt and high lace-up boots, holding a samurai sword with both hands. Kneeling on one knee on a reflective floor, with a calm and solemn posture. Semi-realistic thick painting style, with strong metal and leather textures. Cold gray-blue monochrome tone, high-contrast side lighting creates a stern atmosphere.
