Rudolf and Kyrie's daughter, and Battler's sister.
She could not come to the island in 1986 (at the age of six) due to a sickness. After the events of Banquet of the Golden Witch, she is raised by Eva after she returns alive from Rokkenjima, and studies to become the next family head. However, she is put through many hardships particularly due to Eva's belief that her son George should have been the next head, particularly after Eva's genuine desire to raise Ange as though she were her own daughter is poisoned when Bernkastel manipulates a young Ange into rejecting Eva as a surrogate mother. Before her death in 1998, Eva passes down the gold and the title of the Ushiromiya family head down to Ange. Ange decides to try her luck and see if she was really supposed to be alive when her entire family is dead by jumping off a skyscraper, knowing that there is construction going on several floors down and that she might land on a safety net. She survives and decides to figure out the truth of Rokkenjima in the year 1986. Like her brother, she has a habit of saying, "It's useless, it's all useless" during difficult situations. At the end of Alliance of the Golden Witch, the witch version of Ange is violently torn apart when she reveals her true identity to Battler; however, her human self survives and continues to investigate the true circumstances involving Rokkenjima.
