Using the reference photo as the character-shape source, transform the red printed kaisho glyph into a black brush-calligraphy rendering. Preserve the overall character shape, scale, placement, and white square canvas. Replace the clean red vector-style strokes with solid black ink strokes featuring rough bristle texture, dry-brush fraying, uneven organic edges, and sharp sweeping hane and harai endings. Remove any original font label at the top and add the plain black text label "[GPT Image 2]" in the upper-left corner. Maintain exactly three separated main stroke components matching the reference layout: the large left vertical-cross stroke, the small upper-right dot stroke, and the lower-right sweeping stroke. Minimalist monochrome aesthetic, clean white background, no extra decoration, no watermarks.
