Gudrun

Gudrun (グードルーン, Guudoruun) is an archnoble of Ehrenfest. She is Justus's sister and Traugott's mother.

Gudrun is said to look very similar to her brother, Justus, when he dresses as a woman.

Gudrun was born as Rihyarda's daughter and Justus's sister and raised as an archnoble in Ehrenfest. Her family had a long tradition of service to the archducal family.

Spoiler from Royal Academy Stories - First Year At the royal academy and up to her marriage Gudrun served as one of Lady Georgine's retainers.

After graduating the Royal Academy, she married the unnamed son of Bonifatius and his second wife (Karstedt's younger half-brother). There was some discord in the family due to Gudrun's husband being constantly compared to Karstedt, particularly because Bonifatius's first and second wives were on bad terms. That family conflict persisted even after Gudrun and her husband had their first son, Traugott.

When Rozemyne entered the Royal Academy, the family nominated Traugott to serve as one of her retainers and guard knights.

When Traugott's failings as a retainer come to light, Rozemyne successfully convinces him to resign from his position instead of firing him, effectively limiting the damage done to his family's reputation.

However, Rihyarda is unwilling to let his punishment end there. She meets with Gudrun and her husband to complain about their son's misconduct and scold them for their incompetence in raising such a child. She then summons the entire family, including Karstedt and Bonifatius, to discuss how to punish him. The decision is to assign Traugott his uncle Justus as an attendant to discipline him at the Royal Academy.
