Krauss and Natsuhi's eighteen-year-old daughter. She is an energetic young woman, serving as the student body president at her school, and even leading a rock band. If her father inherits the family fortune, she will become the heiress to the Ushiromiya family, although the family's patriarchal hierarchy denotes her future husband will become the next head. Jessica is tomboyish, feisty, and rebellious, much to the dismay of her mother, who insists she act more refined and ladylike.
