Ushiromiya Hideyoshi

Eva's husband. Hideyoshi is a very jovial man whose cheerful nature manages to tone down the tension between the siblings during their various meetings.

Having lost his family in World War II, he willingly adopted the name "Ushiromiya" when he married Eva. He is the successful president of a chain of fast food restaurants, but seeks Kinzou's fortune due to people trying to buy all the shares in his company.

He speaks with a fake Kansai accent, which he is said to be too embarrassed to use against actual people from the Kansai region of Japan.
