Rodis Castagnier

The eldest son of the Duke of Castagnier. His father Serge, the current head of the family, has renounced his right to succeed to the throne, so he is currently third in line. At his father's request, he studied abroad in the neighboring region since he was a child. He is Margot's second cousin, but they don't know each other. He is a gentle and kind young man.

Perhaps because he has lived in Tokkal for a long time and is unfamiliar with life in Euro, he feels a strong sense of incongruity about Euro's current political system and aristocratic society.
