An 800-year old Genshi Miko or oracle with the form of a young girl. Ulrike comes from a long line of priestesses each chosen by the Original King to act as a channel between him and the people of Shin Makoku. She succeeds Ondine, whose final assignment after retirement was to get Yuri to form a pact with the elements. Ulrike is the one who, at the order of and with additional powers from the Original King, transports Yuri to and from his world to Shin Makoku. Just like all other priestesses, she is not permitted to leave the Original King's castle. Yuri however, once tried to take her out to show her the beautiful world outside but Wolfram barged in thinking he was flirting with her.
At one point in the anime, her "childhood spirit" escaped from her body and went outside to play. Her skills frightened the other children and caused chaos in the village. Ulrike chased after her younger form, and revealed her ability to take on the form of a young woman (as opposed to her current child-like one) to "comfort" her younger self.
