A silver-haired girl in a black robe sits in a green armchair holding a thick book

A girl with silver short hair sits in a dark green velvet armchair, dressed in a black robe with a green-lined uniform, holding an open thick book in her hands, with her legs crossed and raised. Black over-the-knee socks wrap around her calves, and her toes lightly touch the front. The corners of her mouth rise slightly as she lifts her eyes to look ahead. The background is a majestic Gothic library, with wooden shelves arranged beneath a towering stone arched ceiling. Warm golden sunlight spills through narrow windows in the distance, forming a hazy light mist in the air that illuminates floating dust. The scene is composed from a low angle, and the delicate strokes in anime style and soft lighting create a classical yet mysterious atmosphere.
