“BLADE OATH A VOW WRITTEN IN STEEL”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 finished 16:9 anime title card on warm cream washi paper with visible fine fibers. Render exactly two text strings, with no other lettering: the dominant headline “BLADE OATH”, on two centered lines, and the smaller supporting line “A VOW WRITTEN IN STEEL” near the lower edge. Paint the headline as bold Western brush lettering: broad sweeping sumi strokes, irregular asymmetric forms, torn bristle edges, dense black ink at stroke starts, and dry gray trails at exits. Keep every letter unmistakably legible. Place a single katana as the scene subject in the lower-right area, angled upward; define its blade with spare anime cel-style ink contours and a pale paper-colored edge highlight. A decisive black brush slash sweeps behind the title without crossing or obscuring the letters, thinning into gray bristle tails. Use a restricted palette of warm cream, deep matte sumi black, and diluted charcoal gray. Soft diffuse north-facing studio light, no cast shadows, no gradients on the paper, no decorative ornaments, no extra symbols, no border. Keep broad quiet negative space around the typography; clean graphic anime title-card finish.
