character: ayane_(blue_archive) standing in a quiet school library at dusk, leaning slightly against a wooden bookshelf with a stack of accounting ledgers tucked under one arm, soft golden light from a desk lamp pooling across her glasses, calm confident expression half-smile, a small flower hair ornament visible, neat school uniform crisp and tidy, warm atmosphere, detailed background with rows of book spines, gentle rim light from the window behind her. Official Blue Archive key visual illustration style, polished clean linework, vibrant cel shading, soft painterly coloring, high-quality game promotional artwork
