A high-quality anime illustration in a medium shot from a 3/4 view, featuring a beautiful young girl inspired by the name "Shiranui Astray" standing in a futuristic, ethereal void. She is a slender teenager with long, flowing silver hair that shimmers like starlight and deep indigo eyes reflecting a cosmic nebula. She wears a sophisticated blend of traditional Japanese and futuristic attire: a modified white kimono-style dress with metallic silver accents and translucent holographic fabric, paired with sleek, mechanical armor plates on her shoulders and hips. Her expression is serene and mysterious as she gently holds a floating, crystalline shard in her open palm, with her other hand resting gracefully at her side. The background is a surreal expanse of deep space filled with floating white lotus petals and drifting geometric shards of glass, with distant stars twinkling softly. The lighting is cold and atmospheric, dominated by a palette of iridescent whites, silver, and deep navy blue, with soft glowing auras and a shallow depth of field creating a dreamy, celestial mood.
