Ferdinand/Relationships

The Sixth Aub Ehrenfest is Ferdinand's father. They rarely interacted while in Ehrenfest due to Veronica's interference. However, he fondly remembers being praised by his father after making first-in-class among the first years at the Royal Academy, when Veronica was absent. After that, he went all-out in his classes in hopes of earning his father's praise again on the rare opportunities they had to talk.

Shortly after his father's death, Ferdinand was forced to enter the temple to escape Veronica's persecution. He was not able to attend the funeral as his father's son, but rather in an administrative capacity as a blue priest.

Seradina is a mistress of the Sixth Aub Ehrenfest and Ferdinand's mother. Little is known about her except that she failed to protect Ferdinand from Veronica's harrassment.

Rozemyne is Ferdinand's student and legal ward. They have a close relationship: Ferdinand is one of the few people who knows both her past as a commoner in the lower city of Ehrenfest, and her life as Urano Motosu on Earth. When he realizes that her extensive mana capacity will put her in great danger from the nobility, he secures her adoption and fake background as a noble to keep her safe.

Many of Ferdinand's friends are dismayed when they learn he is taking care of a child, but they are surprised by how well the two get along. Rozemyne's quick learning ability, work ethic, and interesting viewpoints always exceed his demanding expectation. In turn, she is not put off by his strict teaching style and values his praise highly. Although they often bicker, and Ferdinand is frequently exasperated by her antics, they share a strong sense of affection and trust.

After sharing her memories using the magic tool, Ferdinand is convinced of her honesty and lets his guard down around her even more than with his retainers Eckhart and Justus, even eating her food without fear of poisoning. He does his best to listen to Rozemyne's viewpoints and values from her first life as Urano and tries to respect them, even when he doesn't share them.

They both tend to worry over one another and can be a bit overprotective. After coming to realize how frail Rozemyne is, Ferdinand routinely checks her health and prevents her from overexhausting herself. She also keeps an eye on his workload, prevents Sylvester from assigning him extra tasks, and drags him out of his workshop to get sleep and eat food at least once a day.

Veronica is Ferdinand's stepmother: the first wife of his father and the mother of his half-brother Sylvester. A paranoid woman who was determined to see her own son become the next Aub Ehrenfest, Veronica was convinced the young Ferdinand wanted to secure the the archduke's position for himself. She bullied him at every opportunity and refused to adopt him, which would have solidified his status as a legitimate archduke candidate. As a result, Ferdinand could only become the next archduke if every other member of the archducal family died.

After his father's death, Veronica's persecution of Ferdinand grew increasingly harsher, to the point that he felt his life was in danger. He ultimately followed his brother's advice to renounce his noble status and flee to the temple where Veronica could not touch him.

Unsurprisingly, Ferdinand loathes Veronica and her entire political faction. While in the temple, he works hard to gather evidence on her crimes to allow Sylvester to formally hold her accountable for her actions. They finally charge her for treason after she forges a permit for Count Bindewald at Bezewanst's request, and she is imprisoned in the Ivory Tower.

Sylvester, the Seventh Aub Ehrenfest, is Ferdinand's half-brother. Despite the harassment Ferdinand endured from Sylvester's mother Veronica, they had a good relationship as children and considered each other siblings.

Sylvester is affectionate toward his little brother, although he often makes unreasonable demands and relies on him to help him manage his duties as an archduke. Because Ferdinand dislikes asking for help, he ends up overworking himself rather than tell Sylvester he can't handle it.

Ferdinand views it as his familial duty to support Sylvester as the archduke. He doesn't hesitate to share his opinions and advice, and Sylvester values his insight.

Georgine is Sylvester's older sister and Ferdinand's half-sister. Because she was so much older than him, they rarely met as children; she was married into Ahrensbach before his time at the Royal Academy.

Ferdinand dislikes her for her similarities to Veronica and views her as a threat to Sylvester, Ehrenfest, and Rozemyne. He works to gather information on her involvement with the former Veronica faction and counteract her political schemes.

Florencia is Ferdinand's sister-in-law.

Wilfried is Sylvester's oldest son and Ferdinand's nephew. At first, they share a mutual dislike. Ferdinand sees Wilfried as a lazy, irresponsible child who isn't worthy of becoming the next archduke; meanwhile, Wilfried was raised by his grandmother Veronica to treat Ferdinand with disdain as a blue priest. At Rozemyne's request, Ferdinand frightens Wilfried into taking his studies more seriously.

When Wilfried enters the Ivory Tower, Ferdinand listens carefully to his explanation and apology. He compliments him for sincerely reflecting on his actions and accepts a softer punishment. While Rozemyne sleeps in her jureve, Ferdinand and Wilfried grow closer as family. Ferdinand also corresponds with Wilfried and advises him on how to best handle Rozemyne at the Royal Academy.

Charlotte is Sylvester's second child and Ferdinand's niece. When Rozemyne was asleep in her jureve, Ferdinand trained Charlotte to take over her Spring Prayer duties and help manage the winter playroom along with her brother, Wilfried.

Melchior is Sylvester's youngest son and Ferdinand's nephew.

Karstedt is Ferdinand's cousin and close friend, as well as the head of the Knight's Order. Ferdinand trusts Karstedt, sometimes visiting his manor to speak to him. Ferdinand shares his thoughts and worries with Karstedt, even asking him to adopt the then Myne.

Elvira is Karstedt's first wife. Ferdinand respects her and her faction completely unaware of her love for him beyond her admiration.

Bonifatius is Ferdinand's uncle. Ferdinand sees him as a headache. He wouldn't leave Ferdinand alone during Rozemyne's term in the jureve, often disrupting him while he was already swamped with work.

Eckhart is Karstedt's eldest son and Ferdinand's loyal guard knight. Ferdinand is aware of how devoted Eckhart is to him and welcomes him as a knight.

Justus is Ferdinand's information gatherer and scholar. Justus, similarly to Eckhart, has devoted his life to serving Ferdinand.

Lasfam is a retainer who takes care of Ferdinand's estate.

Arno was Ferdinand's head attendant until his disloyalty was discovered, after which he climbed the towering staircase.

Fran was Ferdinand's best and most trusted attendant which he transferred to Rozemyne at her arrival at the temple to report on her, serve her loyally, and educate her about her new status.

Zahm is another one of Ferdinand's attendants that he sent to Rozemyne along the way.

Benno is a merchant in the lower city who works closely with Rozemyne. Ferdinand has a camaraderie with Benno thanks to the archduke's unreasonable demands. He requests the Rozemyne send him a warning before being summoned abruptly to spare him the pain of what happened with Haldenzel and Elvira.

Ferdinand's awareness of Lutz is that of someone Rozemyne relies on as well as her only link to her Lower city family.

Myne is Ferdinand's student and assistant in the temple.

Impressed by her quick learning ability and mana, as well as her family's courage in defying the High Bishop, Ferdinand allows her to enter the temple as an apprentice blue shrine maiden and takes responsibility for her education and care. He advises her on how to navigate noble society and cooperates with the Gilberta Company and her family to keep her safe.

Although Ferdiand is a strict teacher and taskmaster, he is usually satisfied with Myne's quick learning ability and hard work. He is frequently baffled by her strange ideas and unpredictable behavior, but is willing to support her as long as she thinks her projects through and explains them to him first. Over time, he becomes fond of her and even somewhat protective: When she is harmed at the trombe extermination, he is furious at the culprit and later apologizes for allowing her to be hurt.

After viewing her memories as Urano Motosu using the magic tool, Ferdinand is convinced that Myne is a sincere and honest person who cares for nothing but books and her family. With the knowledge that she is not a threat, he feels a deeper sense of trust toward Myne and lets his guard down more often. He admires the bond she shares with her family and admits that he is somewhat envious of her happy family life.

Though Bezewanst is his uncle, As he is not a noble, Ferdinand sees him only as a frustrating meddling old man full of unreasonable demands reveling in his status of High Bishop. Ferdinand watches his corruption with disgust and slowly and surely takes over more and more work from him due to his utter incompetence.

Kampfer is a blue priest in the Temple that underwent Ferdinand's grueling training ritual to become competent at their job. He was trained to help Ferdinand with temple paperwork.

Frietack is another blue priest that underwent grueling training to be able to help Ferdinand with temple paperwork.

Though Ferdinand wasn't present during Christine's time at the temple, he respects her love for music and recommends her former retainer, Rosina to Rozemyne as a music teacher and personal musician.

Rihyarda was Sylvester's attendant, and is now Rozemyne's retainer at the castle. She raised Karstedt, Ferdinand and Sylvester (those mostly Sylvester) and holds a certain amount of power over Ferdinand. To his irritation, she calls him "my boy" as he isn't married yet, and Ferdinand goes out of his way to avoid her. Rozemyne used her against him once to make him do the Harspiel Concert, launching a back and forth between Rozemyne and Ferdinand to get petty revenge on each other.
