Despite being 206 years old, Olga has had the appearance of a 6 year old girl for 200 years because of the effects of the Pure Gold. She is tall for her physical age and has long, wavy blonde hair with a red bow on top, large red eyes, and frequently shows her teeth in her expressions. She wears a purple dress, black leggings, and white high heels. The left side of her dress bares the symbol of Alchemi.
