“SINGLE CUT 一太刀”是使用 FontVibe AI 创作的日本水墨毛笔文字效果。把日本书道的水墨毛笔笔法用到拉丁字母上。浓黑的墨汁配上地道的毛笔笔势、单向可控的运笔，还有和纸的质感。做日料店品牌、纹身设计、动漫、武道和文化类项目都特别合适。

Create a tall 9:16 Japanese ink title-card poster, not a generic font sample. Warm cream-white handmade washi paper fills the canvas, visibly fibrous and softly uneven. Soft diffuse north-facing studio light, no cast shadows. Set the exact headline in two centered stacked lines: “SINGLE” above “CUT”. The lettering occupies about 62% of the canvas height, centered slightly above midpoint. Render each Western letter as definitive classical Japanese shodo brush calligraphy: upright harmonious proportions, generous internal counters and letter spacing, bold 5:1 thick-to-thin contrast. Dense near-black sumi pigment pools at loaded stroke centers, transitions to charcoal and transparent gray at the outer pull-away edges; paper absorbs the pigment, creating soft feathered boundaries. Every stroke has one committed loaded-brush entry, controlled mid-stroke pressure, and a precise fine harai taper or upward hane terminal. No uniform black, no hesitant corrections, no digital gloss. Make the word “CUT” the peak moment: a single long, clean diagonal katana-like ink slash travels from lower left through the right side of the word, cutting beyond the last letter into a thinning gray tail. The slash has a dense blunt entry, a narrow sharp exit, and only a few microscopic ink flecks at its entry point. It must feel like one decisive brush action, not blood or damage. Below, centered in very small light-gray brush marks, print “一太刀”. Keep the lower third largely empty. At the upper right, place a faint cropped circular vermilion seal imprint with no legible text. Strong ma negative space, matte paper, no scenery, no ornate decoration, no neon, no metallic effects.
