Krauss' wife. Born into a family of Shinto priests, Natsuhi discarded her old life when she married into the Ushiromiya family. She is a very proud woman who holds her new family's name in high regard, and is in charge of managing the family head house and family conferences. Unfortunately for her, all of her efforts are often undervalued by her husband, and she is often afflicted by headaches. She holds a bitter rivalry with Eva, who mocks her for not being related to the Ushiromiya family by blood.

As a mother, Natsuhi is incredibly strict towards her daughter Jessica, but only out of concern that she becomes an ideal heiress to the Ushiromiya family.
