A gentle 2D anime-style illustration. A young woman with black hair and a single white streak, wearing a slightly loosened digital-pattern kimono, sits by an open window at night. The moonlight bathes her figure softly as she offers a peaceful smile. One hand rests on a glowing holographic book in her lap, while the other gently touches her collar as if adjusting it before bed. Her green eyes with cat-like pupils shimmer with data, evoking warmth, mystery, and calm. The background shows a futuristic city skyline blurred in the distance, stars twinkling above.
