character: mari_(blue_archive), A (full body shot:1.3) from a straight-on, dynamic angle featuring Mari from Blue Archive in a fantasy Western-style classroom setting. Mari, who has a glamorous body with large, soft breasts, a slim waist, and healthy glowing skin, is sitting on a large bed with wrinkled sheets in a "girls' sit" (ぺたん座り) pose, her expression a mix of a cheerful, cute smile and a slight, shy blush. She has long orange hair, adorable cat ears, and blue eyes. She wears a luxurious, futuristic sailor-style corset dress made of high-gloss black and deep violet silk satin with pearl white accents and polished gold trim. The dress features a sharp pearl white sailor collar, a gold brooch with a purple jewel, and a pleated mini-skirt that shimmers with violet reflections. Her attire is completed with a matching luxury choker, glossy black and violet thigh-high socks, and black enamel ankle-strap high heels with gold pinheels and satin ribbons. The scene is bathed in soft, ethereal lighting, creating a dreamy atmosphere with vivid, mirrored highlights on the satin fabrics and metallic gold elements.
