"There was a time when I thought of money as such a worthless thing. I thought, there are so many things in this world that you can't buy with money. But now I understand that that's just a lie! It was just an excuse that have-nots make for themselves!!"—Eva Ushiromiya, Banquet of the Golden Witch
Eva is the only survivor of the Rokkenjima massacre and becomes the sole inheritor of the family's wealth. After the massacre, Eva adopts Ange Ushiromiya, Kyrie Ushiromiya's daughter and the only other living member of the Ushiromiya family. In April 1987, as she is unable to claim the family's inheritance because they were not yet legally declared dead, Eva sold Kinzo's collection of valuable occult books at auction to accrue money.
Eva appears as a woman with fair skin and ginger hair tied into a bun, held together with a purple hairpin. She wears a purple cheongsam, two black gloves of unequal length, a pink bracelet, light blue pants, and black shoes. She has the One-Winged Eagle imprinted all along her cheongsam and tattooed on her left arm.
Eva is both greedy and intensely spiteful. While initially unconcerned with the family headship, she later became obsessed with gaining power within the family as a means of getting back at her brother Krauss for his self-importance regarding his status as next in line for the headship. As a result, Eva attempted to conceive a child before Krauss's wife Natsuhi. Natsuhi's status as "first wife" of the Ushiromiya family causes great resentment within Eva, who frequently attacks and demeans Natsuhi in an effort to appear better than her. When raising George, Eva sought to make him admirable and ideal in every way. After learning he had fallen in love with Shannon, a servant, she became angry.
After Shannon's death in Legend of the Golden Witch, Eva is somewhat relieved because her death meant that George would no longer marry a servant. After discovering Kinzo's gold in Banquet of the Golden Witch, Eva states that she wishes to use the money to bail out her husband's company and leave the rest to her son George. She later states that she wants this because she believes George, instead of her older brother Krauss, is the true successor to the Ushiromiya family.
