Lord Keitaro Orkuz of Begma is a noted photographer and archaeologist, and has studied Trump with both Miki and Mutsumi. He has also done much study with King Tylor in the arts of political leadership, in preparation for taking over the role of Prime Minister of Begma from his mother, Nadia Orkuz.
He is very well-liked by the family of Amber, although he and Kentaro hate each other passionately. He has no less than three Princesses of Amber romantically interested in him (or at least, apparently so): Mutsumi, Naru, and Shinobu Minor.
This situation seems to have resolved itself, with him hooking up with Shinobu Minor.
