Futuristic Anime VTuber Debut Teaser Poster

Vertical promotional teaser poster for a futuristic anime VTuber idol debut. Center-right foreground features [Amaha Mirai], a cheerful young anime idol girl with long flowing [silvery white with pale blue and pink highlights] hair, large blue-violet eyes, an open smile, soft blush, and a headset microphone, dynamically reaching one hand toward the viewer. She wears a futuristic white and pastel blue cropped idol jacket with pink accents, metallic trim, star pins, belts, and a short layered translucent iridescent skirt. Exactly 3 visible hair accessories: a large ribbon bow on the right side, a small star clip on the left bangs, and a cluster of two small pink pins on the right bangs. Setting: A glowing futuristic cyberpunk city canyon of glass skyscrapers with five key elements: a giant holographic billboard on the left displaying the same idol with "LIVE" styling, a small flying camera drone in the upper-left sky, a tall needle-like central tower, a neon triangular sign in the lower left, and a bright holographic sign on the right building. Pink petal confetti, star sparkles, light streaks, and lens flares drift across the air. Typography & Graphic Layout: At the top, bold glowing Japanese title text reading "[天羽ミライ]" with small spaced letters above reading "AMAHA MIRAI". Across the lower middle, a glowing slogan reading "[きらめく未来に、ログイン。]". At the very bottom, a launch notice reading "[近日始動]" framed by small star symbols and sci-fi divider lines. All text is stylized, luminous, and sharp without covering the character's face or reaching hand. Lighting & Style: High-energy commercial anime key visual, polished cyber-pop aesthetic, vibrant cyan, electric blue, magenta, lavender, and crisp white rim lighting with sparkling bloom and clean linework.
