"Let's tense up our assholes and do this thing."—Rudolf Ushiromiya, Banquet of the Golden Witch
Rudolf Ushiromiya (右代宮 留弗夫, Ushiromiya Rudorufu) is Kinzo Ushiromiya's third child. Rudolf lost his first wife, Asumu, six years prior to the start of Umineko no Naku Koro ni and immediately remarried with his longtime lover and business partner Kyrie. He often works alongside his sister Eva to stop their eldest brother Krauss from monopolizing Kinzo's fortune.
Rudolf has a history of unscrupulous behavior starting with his swindles when selling party tickets during his years in university. He's a lifelong playboy who has toyed with several women's feelings for the amusement of watching them fight over him, a history which has earned him the ire of his daughter Ange. He is talented at sports, particularly at figure skating.
After the death of his first wife, Asumu, Rudolf immediately married Kyrie. He claims to have done this due to Kyrie's pregnancy; he wanted to ensure that his second child, Ange, would be raised in a family with two parents.
Rudolf is also a successful businessman, though he has a habit of using fraudulent practices to enhance his profits.
Rudolf appears as a clean-shaven man with swept-back brown hair. He wears white shoes and a navy blue suit over a black shirt and white tie. The left lapel of his suit as well as the left leg of his pants are imprinted with the One-Winged Eagle.
Rudolf has a history of infidelity. His affair with Kyrie while he was married to Asumu is what led to the schism between him and Battler.
Twilight of the Golden Witch
During the Halloween party, Ange Ushiromiya steals some of Rudolf's wine, which she refers to as "adult grape juice." Rudolf is the fifteenth person to pose a quiz to Ange during the Halloween party. Like his wife, Kyrie, his puzzle centers around three girls: Miyoko, Satoko, and Rika. After Ange solves his puzzle, he speaks to Kyrie in private, saying "I...might be killed tonight," a repetition of a quote he first said in Legend of the Golden Witch. He then reveals the truth of Battler's parentage.
- Rudolf's suit is somewhat unusual as all three buttons of his suit are buttoned, a deviation from the conventional style of buttoning only the top two buttons on a three-button single breasted suit.
