Girl anime poster, starry sky, futuristic elegance

A vertical Japanese anime fantasy game or light novel promotional poster, using soft pale purple, white, and gold tones, featuring a heroic young girl as the protagonist, with a magnificent city in the sky as the background. She is in a dynamic three-quarter full-body pose, body slightly turned to the left, holding an ornate staff in her left hand and stretching her right hand backward, as if in the wind. Her face is covered by a flat pale square mask positioned over her head, but the visible design suggests a refined anime heroine with extremely long flowing silver-lilac hair, side bangs, loose strands, and a star-shaped hair ornament with a deep indigo ribbon bow. She wears an exquisite magical-girl-style dress: an off-shoulder white bodice with navy blue and violet trim and gold star motifs; an asymmetrical layered skirt with colors blending white, periwinkle blue, violet, and deep indigo; adorned at the waist with a large deep blue bow and a gold star-shaped gem; with detached flowing sleeves, gold chains with tiny star charms hanging at the hips, wearing white over-the-knee socks with blue star-shaped garter straps on her thighs. Her staff is tall and elegant, with a dark shaft featuring gold frame elements, a faceted blue crystal suspended near the top, and decorated with bows and stars. The background is an airy fantasy skyline containing white towers, cathedral-like spires, clouds, feathers, and falling pink petals, accompanied by bright ethereal backlighting and a dreamlike heroic atmosphere. The composition imitates a refined key visual poster and integrates rich Japanese typography into the image. In the upper left, place the Japanese slogan “願いが、未来を照らす。”, with two lines of smaller text below. In the upper right, place a star-shaped emblem, the large character name “ルミナ”, the subtitle “— Lumina —”, and a line of smaller voice actor information. On the right side, add 3 vertically arranged feature callouts, each containing a small icon, a bold Japanese title, and two lines of smaller text below. On the left side, add a block of Japanese text arranged vertically along the side of the character. In the lower right, include 3 diagonally stacked small portrait illustrations of the character: 1 calm frontal expression, 1 serious side-profile expression, and 1 closed-eyes smiling expression. In the lower left, place the large Japanese title “星紡ぐレガシア”, with the English subtitle “— LEGACIA: Weave the Stars —” below. In the lower right corner, add the date text “2025. 夏” and a line of short Japanese slogan below. At the bottommost edge, include 2 small social or website info blocks on the left, and a line of tiny copyright text on the right. Use a high-end modern anime promotional illustration style, presenting a bright soft fantasy atmosphere, elegant composition, fluid lines and colors, soft cel shading, delicate fabric movement, glossy highlights, intricate costume details, a clean typographic layout, and refined commercial poster quality.
