Anime illustration of Satono Diamond, a female character with long brown hair, brown eyes and brown horse ears. She wears a green and white "Natural Brilliance" costume with gold embroidery and black thigh-high stockings. Her outfit includes a green cape with gold accents, a white ruffled blouse with puffed sleeves, a diamond-shaped brooch and a black neck scarf with gold patterns at chest, and a black corset. A green bow with white ruffled ribbon is on her right side. She has a gold tassel-like accessory on her right side of her skirt. She sits with her legs slightly apart, showing the hem of her skirt. The background is a bright, softly lit window with light streaming in. Her expression is gentle, with a slight smile and blush on her cheeks. She holds her arms up to her chest.
