Krauss and Natsuhi's eighteen-year-old daughter. She is an energetic young girl, 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. She dislikes her parents at times for the pressures they place on her regarding the family inheritance, which she has no interest in. However, she still shows concern for them deep down. She was born with weak bronchi, and occasionally suffers from asthma attacks. She is in love with Kanon, who tries to hide his own feelings from her, though she manages to reach out to him in Dawn of the Golden Witch, and they become a couple. She is willing to go to great lengths to gain Kanon's respect, and tries to avoid doing anything that could jeopardize that. Jessica is shown to be skilled with brass knuckles in Alliance of the Golden Witch.
Kinzo's fourth child. As the youngest of her siblings, she has the least influence at the family conference. Her husband abandoned her shortly before the birth of her daughter and only child, Maria. Rosa is the president of a small design company, "Anti-Rosa," which has recently begun to flounder, and thus seeks out Kinzo's inheritance to pay off her co-endorsers. On the surface, Rosa appears to be the most sensible and soothing of all the siblings. However, as a result of being downtrodden by her older siblings in her childhood and forced to endure the pressures of a single mother, she frequently loses control of her emotions and responds violently to her daughter's childish behavior and overenthusiastic approach to the occult. While Rosa thought that Maria saying 'uu-uu' was charming for a while, she eventually grew frustrated with it, and often resorted to hitting her. Whenever Rosa hits Maria, Maria says that she has been taken over by "the black witch."
Kinzo's second child. Under normal circumstances, she would have lost her place in the Ushiromiya family when she married, though she managed to retain her name on the family register when she had her husband Hideyoshi adopted into the family and gave birth to Kinzo's first grandchild, George. Eva is cheerful and mischievous, but also sinister and greedy. She is hostile towards her older brother Krauss, and rallies the other siblings against him in their fight for the family inheritance. She also looks down on Krauss's wife Natsuhi for not being related to the Ushiromiya family by blood. Because she believes George to be the rightful head of the Ushiromiya family, she is cruel towards the servant Shannon, as she suspects her of being his lover. Despite her insidious personality, however, she treasures her husband and son more than anything, but fears that she is too domineering towards them. She is skilled in various martial arts, and said to be excellent at cooking. In Banquet of the Golden Witch, Eva solves the riddle of Beatrice's epitaph and returns from Rokkenjima as the head of the Ushiromiya family and sole survivor of the murder incident, but is unable to overcome the grief over losing her husband and son. As depicted in the story and TIPS of Alliance of the Golden Witch, Eva lives miserably for the next twelve years as the guardian of Ange, the only other surviving member of the Ushiromiya family, resenting her for "stealing" the role of the family heir from George until she dies of acute heart failure in the year 1998.

Ootsuki is the foremost Japanese member of the Witch Hunt, an international organization of occult enthusiasts dedicated to researching the tragedy on Rokkenjima from a magical perspective. However, their presence and activities are less than welcome by the surviving members of the victims on Rokkenjima, having stirred up the tabloids in a very unpleasant light. The name of this organization was borrowed from the English fan translation group for the game, also called "Witch Hunt."
