A high-quality anime illustration in a modern Reiwa animation style, featuring a medium shot of a lovely young girl standing in a sun-drenched, historic library. She has a delicate complexion with light pink blush, deep purple eyes with complex gradients, and platinum blonde extra-long twintails with curled ends, adorned with pink ribbons with crystals and pearls and a gold hairpin. She wears a matte pastel pink double-breasted jacket draped over her shoulders, revealing a geometric patterned lining, a white shirt with a loosely tied pale pink tie, pink high-waisted short shorts with a charm belt, and glossy white enamel thigh-high boots with detailed garter buckles. Her body is slightly twisted, weight on her left leg; her right hand gently tucks hair behind her ear, while her left hand holds an old book. She looks slightly away and upward with a mysterious, shy expression. The background consists of towering wooden bookshelves filled with old books and an antique desk, with warm sunlight streaming through stained-glass windows, illuminating floating dust motes. The image uses clean cell-shading with distinct boundaries, a fixed warm light source from the side, and color-traced linework that blends naturally with the surrounding hues, creating a silent, ethereal atmosphere with a shallow depth of field.
