Heisei Trend Phrase Anime Poster

Goal: Create a bright square anime reaction-gacha poster featuring an energetic idol schoolgirl pointing directly at the viewer, themed around a Heisei-era trendy phrase reaction. Canvas: 1:1 square illustration, high-resolution, colorful Japanese pop poster composition with a sticker-like graphic design. Main subject: A cute anime girl, {argument name="character name" default="Airi"}, shown from thighs up on the right half of the image. She has short glossy navy-black bob hair with subtle purple highlights, warm brown eyes, one eye winking, flushed cheeks, and an open cheerful smile. She points her index finger toward the camera with strong foreshortening, while her other hand rests confidently on her hip. She wears a white sailor-style school idol uniform with orange collar, orange neckerchief, orange sleeve cuffs, orange pleated skirt, orange choker, small heart earrings, and a large orange flower-and-ribbon hair accessory with a star gem. Layout: Place the character on the right-center foreground with a thick white sticker outline. On the left side, include one huge vertical Japanese catchphrase in bold red letters with cream fill highlights and thick white/yellow outline: {argument name="main phrase" default="今でしょ!"}. At the top left, include a small tilted sign reading {argument name="era label" default="平成"}. Near the top center-left, add a smaller orange title reading {argument name="gacha title" default="流行語ガチャ"}. At the lower left, add one comic speech burst containing three text parts: small blue 「はい!」, large pink 「そこ!」, and blue 「テストに出るよ!!」. Background: Vibrant orange and golden radial burst background with halftone dots, confetti speckles, sparkles, and a festive game-show energy. Use warm gradients and high contrast. Discrete decorative elements: Include exactly 5 large sticker-style decorations around the character and text: 1 yellow star at the upper right, 1 teal star at the mid-right, 1 red star near the lower center-left, 1 yellow star at the lower left, and 1 set of two cream exclamation-ray marks on the right side. Add small white sparkle glints throughout the background. Visual style: Polished modern anime illustration, glossy eyes, clean line art, saturated orange palette, dynamic perspective, playful Japanese variety-show typography, thick sticker outlines, energetic and cute. Constraints: Keep all visible Japanese text legible and in the specified positions. Do not add extra characters, extra speech bubbles, logos, watermarks, or unrelated text.
