The elderly head of the Ushiromiya family, and the owner of Rokkenjima. Kinzo holds his children in contempt, viewing them as vultures ready to feast on his inheritance as soon as he dies (or at least when word of his death spread out). He rarely leaves his exceedingly vast study, which contains various commodities such as a bed, lavatory, and bath. He is also a rabid practitioner of black magic and the occult, his shelves lined with volumes upon volumes of grimoires. One of his most prominent obsessions is Beatrice, a witch he is said to have summoned and contracted for ten tons worth of gold. He is deceased by the beginning of the series, having succumbed to a long-time drinking habit. However, his oldest son Krauss, Krauss's wife Natsuhi, his personal physician Nanjo, and all the mansion's servants (except for Gohda) maintain the illusion at the family conference that he is still alive, albeit with a three-month life expectancy; any interactions between Kinzo and any other characters are meant to sell the deception to the reader regarding the true events. Throughout the first four games, Kinzo's body frequently turns up burnt in the incinerator of the mansion's underground boiler room as a means to conceal how long he had been dead, and is identified as Kinzo due to his polydactyly, distinguished by having six toes on each foot.
Masayuki is the son of Terumasa Nanjo who inherited his father's clinic on Niijima after his death in 1986. Due to his family's sensitivity to Terumasa's death, Masayuki is resentful of the media for its rather flippant depiction of the murder incident on Rokkenjima, and prefers to keep quiet about it. He is interrogated by Ange during her own investigation of the incident, only opening up to her as a fellow victim who lost her family. (from: Wikipedia)
She is a "substitute actor" without a personality that acts as a vessel to personify both Beatrice and the rules of her game, she was created by Bernkastel to be the "reader" of the seventh game, Requiem of the Golden Witch, similar to the role that Ange held during Dawn of the Golden Witch. Her name signifies that she is the final guide of Beatrice's game. Clair can be considered a tool rather than a person, allowing Yasu to confess to Willard H. Wright, Lion Ushiromiya, and Bernkastel without revealing Yasu's own "pitiful form." She exists only in the meta-world and doesn't appear within the game board. Also she is the original form of Yasu's Beatrice, who is made to match the image of a ghost that haunts Rokkenjima with a pure white dress and contrasting personality.
