Futuristic VTuber Debut Poster
Goal: Create a glossy VTuber-style teaser key visual for a futuristic idol debut, centered on character_name, with strong character presence and high-energy anime advertising design. Canvas: Vertical 3:4 poster, full bleed, ultra-detailed anime illustration, vibrant cyan, electric blue, magenta, lavender, and white lighting, sparkling bloom effects, clean commercial finish. Layout: Put a huge glowing Japanese title across the top reading main_title_text, with small spaced roman letters above it reading “AMAHA MIRAI”. Center-right foreground shows the VTuber idol reaching one hand toward the viewer in dynamic perspective. The background is a bright futuristic city canyon with holographic billboards and glass skyscrapers. Across the lower middle, add a glowing slogan line reading slogan_text. At the very bottom, add a smaller launch notice reading launch_text, framed by tiny star symbols and decorative sci-fi divider lines. Subject details: Draw one cheerful young anime idol girl with long flowing hair_color hair, large blue-violet eyes, open smiling mouth, soft blush, and a headset microphone. She wears a futuristic cropped idol jacket in white and pastel blue with pink accents, star pins, metallic trims, a short layered translucent skirt, belts, straps, and iridescent fabric details. Add hair accessories: exactly 3 visible accessories — one large bow-and-ribbon ornament on the right side of her head, one small star clip near the left bangs, and two small pink hairpins grouped on the right bangs as a single accessory cluster. Background elements: Include exactly 5 prominent futuristic promotional elements — one giant holographic billboard on the left showing the same idol with “LIVE” styling, one small flying camera drone near the upper-left sky, one central needle-like tower, one neon triangular sign in the lower-left corner, and one bright holographic sign on the right building. Fill the scene with pink flower-petal confetti, star sparkles, lens flares, and light streaks. Visual style: Modern Japanese anime poster, high-saturation cyber-pop city, luminous rim lighting, crisp linework, detailed hair strands, polished VTuber debut advertisement aesthetic, energetic perspective, dreamy yet sharp. Constraints: Keep the image as a single poster, no extra characters, no logo watermark, make all text large and decorative but legible, preserve the Japanese text exactly as specified in the slots, and avoid cluttering the face or outstretched hand with text.
