Celestial Sci-Fi Gacha Nun Concept

Full-body vertical character concept illustration of an elegant futuristic celestial nun or angel named [Luna] in Chinese gacha-game key art style. She stands front-facing in a perfectly centered, symmetrical pose on a pale glossy reflective floor. She has extremely long flowing [silvery white with faint lavender-blue highlights] hair cascading past her knees, a luminous thin halo above her head, and a soft blank pale-lavender square obscuring her face area instead of facial features. Her outfit is a layered white ceremonial dress with translucent veils, sheer cape panels, crystalline fabric, a fitted bodice, long detached sleeves, high collar with a black inner chest panel, silver cross-like ornaments, a thin dark belt, tiny red accent ribbons, and white high-heeled boots. Delicate glowing constellation lines, star sparkles, prismatic refractions, pale violet-blue magical light, and transparent glassy polygonal fabric edges accent her garment. Main color palette of [white, ice blue, pale lavender, silver, and tiny red accents]. Background is a minimalist sacred sci-fi temple interface with soft white walls, faint circular halo diagrams, thin vertical guide lines, tiny decorative symbols, and subtle Chinese inscriptions reading "[彼岸代光]" on both sides. Clean anime linework, soft bloom lighting, ethereal mood, no extra characters, no weapons, no logos.
