Ortwin

Ortuin (オルトヴィーン, Orutoviin) is an archduke candidate from Drewanchel who currently attends the Royal Academy. He is the younger brother of Adolphine.

According to his classmate, Wilfried, Ortuin is “quite intelligent”.

Although Ortuin is in the same year as Rozemyne, they rarely interact because of how quickly she passes her classes. He is better acquainted with Wilfried.

After Rozemyne's return to the Royal Academy, Ehrenfest sent out invitations to all duchies for a final tea party before the Interduchy Tournament. Due to a limit on the number of people they can accommodate, they ask that each duchy only send one person (and their retainers) to attend. Ortuin is eager to go to the tea party; however, his sister Adolphine claims the spot for herself.
