A flat, clean anime style illustration inspired by Blue Archive, featuring an elegant older sister figure with a curvaceous build and large breasts. She has medium-length brown hair and striking red eyes, framed by stylish glasses. She is dressed in a layered outfit consisting of a fitted grey top underneath an oversized white coat that is partially unbuttoned and draped loosely off her shoulders, revealing the grey garment. The background is simple and uncluttered. The art style utilizes soft pastel palettes, minimal shading, and smooth color fills to define simple, rounded forms. Linework is light and precise, emphasizing a polished and gentle aesthetic with no heavy gradients or complex textures.
