A vertical Japanese anime fantasy game or light-novel promotional poster in a soft pastel lavender, white, and gold palette, featuring a single heroic teenage girl as the main subject in a grand celestial city. She stands in a dynamic three-quarter full-body pose, slightly turned left, holding an ornate staff in her left hand, with her right arm extended behind her as if caught in wind. She is a delicate anime heroine with a clearly visible, fully rendered face — large expressive violet eyes, soft delicate features, and a gentle confident expression — with very long flowing silver-lilac hair, side bangs, loose strands, and star-shaped hair ornaments with dark indigo ribbon bows. She wears an elaborate magical-girl style dress: off-shoulder white bodice with navy and violet trim, gold star motifs, layered asymmetrical skirt in white, periwinkle, violet, and deep indigo, a very large dark blue waist bow with a gold star jewel, detached flowing sleeves, gold chains with tiny star charms draped at the hip, white thigh-high stockings, and a blue star-shaped garter ornament on one thigh. Her staff is tall and elegant, dark shaft with gold frame elements and a suspended faceted blue crystal near the top, decorated with bows and star accents. The background is an airy fantasy skyline of white towers, cathedral-like spires, clouds, feathers, and drifting pink petals, with bright ethereal backlighting and a dreamy heroic atmosphere. Compose it like a polished key visual poster with abundant Japanese typography integrated into the artwork. At the upper left, place the Japanese tagline text "願いが、未来を照らす。" with two smaller lines below it. At the upper right, place a star-like emblem, the large character name "ルミナ", the subtitle "— Lumina —", and a smaller CV credit line. On the right side, add 3 vertically stacked feature callouts, each with a small icon and a bold Japanese heading followed by 2 short lines of smaller text. On the left side, add 1 vertical Japanese copy block running downward beside the character. At the lower right, include 3 small portrait inset panels of the same girl, stacked diagonally: 1 calm front-facing expression, 1 side-profile serious expression, and 1 smiling eyes-closed expression. At the lower left, place the large Japanese title "星紡ぐレガシア" with the English subtitle "— LEGACIA: Weave the Stars —" beneath it. At the bottom right, add the date text "2025. 夏" and one short Japanese tagline line below. At the very bottom edge, include 2 small social or website info blocks on the left and a tiny copyright line on the right. Render in high-end modern anime promotional illustration style, luminous pastel fantasy atmosphere, elegant composition, smooth linework and coloring, soft cel shading, delicate fabric movement, glossy highlights, intricate costume details, clean typography layout, and refined commercial poster finish.
