动漫摇滚乐队演唱会海报

Goal: Create a highly detailed vertical anime rock-band concert poster for June 9 Rock Day, featuring an all-girl band named {argument name="band name" default="RainRebellion"} performing on a glittering night stage under cherry blossoms.

Canvas: Vertical poster, 2:3 aspect ratio, dense information-rich layout, glossy idol-anime key visual style, dramatic blue-purple-pink concert lighting, sparkling lens flares, neon reflections, floating sakura petals, metal scaffolding, spotlights, cables, speakers, drums, guitars, and ornate fantasy decorations.

Main layout: Put 5 young female anime band members on stage in a heroic triangular composition, with the lead vocalist largest in the center foreground. Add 1 small mascot character in the lower right, making exactly 6 character figures total. Use a luxurious, maximalist visual style with intricate accessories, gothic-rock idol outfits, ribbons, roses, lace, belts, chains, star motifs, translucent jackets, and musical instruments.

Characters and instruments, exactly 5 band members plus 1 mascot:
1. Center: {argument name="lead vocalist name" default="Mio"}, lead vocalist, blonde bob haircut, black off-shoulder rock T-shirt with cute chibi band art printed on it, short frilly skirt, layered necklaces, bracelets, holding a vintage microphone on a stand, confident frontwoman pose.
2. Upper left: Hina, guitarist, long dark purple hair with blue-pink highlights and floral hair ornaments, playing an electric guitar, energetic side pose.
3. Lower left: Rin, bassist, aqua/turquoise twin-tail hair, black floral gothic outfit, playing a decorated bass guitar, cool intense pose.
4. Upper right: Yuzu, drummer, long blonde hair, seated behind a drum kit labeled with the band name, raising drumsticks, with a small flag reading “Victory!”.
5. Right middle: Luna, keyboardist, long silver-lavender hair, elegant black-and-blue outfit, playing a luminous electronic keyboard, calm mysterious expression.
6. Lower right: Rocky, small mascot character with brown hair and animal-like charm, holding a microphone, cute hype-man pose.

Text content and typography: Add Japanese-style promotional poster text with glowing hand-lettered and serif typography. At top left include “6月9日”, “ロックの日SP”, large headline “ロックバンド作ろ♪”, and pink script “ver.2”. At right side, add vertical Japanese slogan “私たちの音で 明日を塗り替えよう.” Center bottom: large ornate glowing logo “{argument name="band name" default="RainRebellion"}” with small katakana subtitle “レイン・リベリオン”, surrounded by silver filigree, wings, roses, and blue gems. Below the logo create exactly 5 circular character profile badges labeled: “Mio Vocal”, “Hina Guitar”, “Rin Bass”, “Yuzu Drums”, and “Luna Keyboard”, each with a tiny portrait icon and a short Japanese tagline beneath. At lower left add concert information: “NEXT LIVE”, “RainRebellion 1st Oneman Live”, “Breaking the Rain”, “6.9 (MON) @Eternal Stage”, and tiny opening/start time details. At bottom center add the slogan “雨降って 地固まる。” and the English line “We will rock the future together”. At lower right add a circular “RR” crest logo with “RainRebellion”.

Visual style: Ultra-detailed modern anime illustration, idol rhythm-game poster, dynamic stage lighting, blue and violet neon glow, pink sakura petals, magical sparkles, chrome highlights, deep contrast, ornate typography, crisp line art, high saturation, cinematic composition, polished commercial key art.

Constraints: Keep exactly 5 band member profile badges and exactly 6 character figures total. Keep the poster packed but readable. Do not add extra band members. Avoid photorealism; keep it anime-style. Make the band name logo the largest text element in the lower third.
