「77」は FontVibe AI で作成した血のしたたるフォントの文字エフェクトです。濡れた暗赤色の表面を持つ太い深紅の文字。長い血の滴は丸い粒で終わり、横からの光を受けて真っ黒な背景に浮かびます。

Thick crimson blood saturating every surface — viscous, high-density fluid with authentic physical behavior: large tear-shaped drops suspended at each drip terminus with surface tension visible at the meniscus, connecting streams thinning as they extend downward, deep near-black pooling where blood accumulates. Material properties: subsurface scattering gives deep red glow when backlit, specular gloss on convex drip surfaces catching directional light, matte-dark at clotted pooling zones. Blood color gradient from bright arterial red (#CC0000) at active drip streams to near-black clot (#3D0000) at base pools. Gravity-driven physics — every drip pulled downward with anatomically accurate tension. Horror film practical effects quality — not painted, not stylized, photorealistic blood. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the viscous blood fluid physics, the suspended drips and the pooling. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as viscous crimson blood letters with tear-shaped drops held by surface tension, thinning connecting streams and near-black pooling. COLOR PRIORITY: keep the font's own colors if specified; otherwise arterial red (#CC0000) grading to near-black clot (#3D0000). Square composition, with “77” dominating the center in two enormous crimson forms, spaced closely as a single title. Surround every visible edge with viscous, high-density blood: thick drips swell at their source, taper into narrow gravity-pulled streams, and end in suspended, rounded teardrops with taut glossy menisci. Keep the fluid physically heavy, not watery or painted. Grade the blood from arterial crimson to deep maroon, with near-black clotted shadows and small pools gathered beneath the numerals. A cold, narrow side light skims the wet convex surfaces, creating sharp dark-red highlights and plunging the opposite sides into shadow. Let the numeral surfaces carry a restrained slick sheen, while pooled blood turns matte and almost black. Set everything against an uninterrupted pure-black void; no warm tones, scenery, splatter decoration, or additional text. A few tiny suspended droplets near the longest drips add scale without clutter. The composition should feel stark, visceral, and ominous, with clear negative space around the central title and the hanging drops.
