Benedict-Amis Hamilton

Margot's uncle. The younger brother of the former empress Ursula. He was unable to obtain the throne for the reason that he did not have the "noble violet color", and was later ordered by his grandfather Adolph to establish a branch family, the Duke of Hamilton. There are rumors that he and Ursula had a feud prior to her death, although the truth has never surfaced.

He currently holds the second place in the line of succession to the throne, but if Margot has a child, his rank may drop. In order to oppose it, it is said that he openly expands his power through political marriages with influential nobles. In aristocratic society, he is famous as a hobbyist who loves art.
