Korisu is younger than any of the other girls. She has blonde hair, and wears a simple sailor themed dress and hat, a string necktie and leather belt, and two small buckle shoes. She often quietly but intently stares with her bright red eyes. Her Nero Alice outfit is based on the Victorian-era character Alice. She wears a long dress, overlaid with an apron, and 2 large ribbons, one atop her head and another around her waist, tied at the back. 3 stars appear across her forehead.
