Sengoku vs Sangoku Crossover Poster

A dramatic ultra-detailed vertical anime key visual poster showing a crossover war between Japan’s Sengoku era and China’s Three Kingdoms era, split exactly down the center by a glowing vertical beam of light. The left half is themed in crimson, magenta, ember orange, and cherry blossom pink, representing {argument name="left faction title" default="日本戦国"}; the right half is themed in jade green, teal, cyan, gold, and stormy blue, representing {argument name="right faction title" default="中国三国"}. At the center, large vertical Japanese calligraphy reads {argument name="center slogan" default="時空を越え、宿命が交錯する。"}. The composition is dense, cinematic, and symmetrical, like a premium game or movie crossover poster, with dozens of sparks, petals, glowing particles, motion streaks, and layered background architecture. On the left side, depict 4 distinct Sengoku-themed warriors. At the top left, a stern samurai warlord in ornate black and deep red armor with gold trim, long dark hair tied high and blowing in the wind, shown in a powerful upper-body portrait facing inward; behind him are sakura blossoms, banners, and stacked Japanese castles illuminated with neon-magenta highlights. Mid-left, show 1 battle-hardened older general with wild silver hair, heavy layered armor, and a fierce glare, partially emerging from the fortress cityscape. Lower-left, show 1 aggressive crimson-clad warrior lunging forward with sweeping cloth, horned or antler-like helmet ornamentation, and dynamic red-black armor. At the bottom-left foreground, show 1 dominant swordsman in demonic samurai armor with a crescent-moon helmet crest and glowing red eyes, gripping a katana angled diagonally downward, surrounded by embers and petals. A vertical banner near the upper-left edge displays the Japanese text 日本戦国. On the right side, depict 4 distinct Three Kingdoms-themed heroes. At the top right, show 1 regal strategist-emperor figure in elaborate blue, black, and gold ceremonial armor with a tall crown-like headdress, shown in upper-body profile facing inward; behind him rises a luminous spectral dragon made of water, cloud, and light. Mid-right, show 1 long-bearded green-robed general with a tall headpiece and lamellar armor, solemn and heroic, framed by neon-lit city structures and swirling magical energy. Slightly below center-right, show 1 elegant strategist-scholar holding an opened feather fan, wearing layered robes and gold ornaments, calm and calculating. At the lower-right edge, show 1 roaring armored warrior with a fierce expression and windblown hair. In the bottom-right foreground, make the dominant figure a green-and-gold armored hero extending a glowing jade-green sword toward the viewer, with flowing robes and luminous energy ribbons curling around the blade. A vertical banner near the upper-right edge displays the Chinese text 中国三国. Blend historical East Asian war aesthetics with futuristic cyberpunk megacity elements: Japanese pagodas and fortresses on the left, neon skyscrapers and glowing urban lights across both halves, flying fortress silhouettes and distant airborne warships in the sky, magical lightning, smoke, and storm clouds overhead. The sky transitions from sunset violet and rose on the left to stormy turquoise and silver on the right. Use hyper-detailed painterly anime illustration, intricate armor textures, metallic reflections, volumetric lighting, high contrast, epic scale, and intense atmosphere. At the bottom, add huge stylized title typography: on the left, massive fiery kanji 戦国 with the romanization SENGOKU beneath it; in the middle, a metallic gold VS; on the right, massive jade-glowing kanji 三国 with the romanization SANGOKU beneath it. Below that, add a smaller centered subtitle line reading SENGOKU VS SANGOKU, and beneath it a Japanese tagline: {argument name="bottom tagline" default="時空を超え、英雄たちの戦いが始まる。"}. Poster layout, polished commercial promotional art, extremely detailed, high-impact, collectible poster aesthetic.
