Ferdinand

Ferdinand (フェルディナンド, Ferudinando) is the High Priest of the Ehrenfest temple who served as Myne’s teacher. He later becomes Rozemyne’s guardian and mentor.

As the son of the Sixth Aub Ehrenfest and a mistress, Ferdinand is the half-brother of Sylvester and an archduke candidate of Ehrenfest.

Ferdinand has light gold eyes and pale blue hair that falls to his shoulders. He is tall and has a slender build. Generally, his face reveals little emotion. In noblewomen's society, Ferdinand is considered very attractive.

When Myne first encounters him, she thinks he looks around the same age as Benno, although he is actually about ten years younger. His worn appearance is primarily due to overwork, and he tends to look closer to his real age when he has more time to relax.

As Ferdinand often says himself, he does not have a naturally “likeable” personality. He treats most people coldly unless he has reason to believe they are valuable to him, and only bothers with politeness when it benefits him. As an opponent, Ferdinand is calculating and ruthless: He exploits every weakness without restraint to secure the best possible result for himself. Likely as a result of the long and intense abuse he suffered from Veronica, he is especially distrustful, cold and impatient with women.

However, Ferdinand is deeply loyal and will go to great lengths to protect and support the few people he cares about. Despite his often solitary life, he values personal relationships highly, and he admits to Myne that he envies the unconditional love and support she receives from her family.

Due to his difficult upbringing, Ferdinand rarely expresses his emotions outwardly and maintains a calm, pragmatic attitude. When he does show kindness or concern, he tends to do it in a roundabout and hard-to-understand manner. He also is good at hiding discomfort and pain: the more upset he is, the brighter he smiles.

An exceptionally competent and hardworking person, Ferdinand values those same qualities in others. However, he has no patience for those who cannot meet his standards. Myne reflects that he often tries to do everything himself rather than rely on others. Ferdinand also loves research and often forgets to eat or sleep when he’s studying a fascinating topic.

Ferdinand is described as a cold-blooded pragmatist who cares about almost nothing but efficiency. He would give only explanations and orders that are as short and to the point as possible to save time, create potions that maximize effectiveness but are absolutely repugnant, or traumatize people to teach them a lesson. Ironically, this habit sometimes end up causing delays due to the recipient not fully understanding his intentions. For example, he told Rozemyne to strip during a medical examination, which caused a slew of misunderstandings and troubles. Going into a little more detail and telling her to remove her socks and expose the back of her torso would have led to her immediate compliance.

Ferdinand is the son of the Sixth Aub Ehrenfest and Seradina, his mistress, making him an archduke candidate of Ehrenfest. He was raised in noble society and trained to support his half-brother Sylvester, who was favored to be the next Aub Ehrenfest.

Because Ferdinand’s mother was not a legal wife of the Aub, and Veronica refused to adopt him, he could not legally become the archduke unless every other member of the archducal family died. Nevertheless, Veronica viewed him as a threat to her son’s future position and routinely harassed and ostracized him.

At age ten, Ferdinand enrolled in the Royal Academy, where he excelled in his studies. After Justus told him it was possible to enroll in multiple courses, he decided to simultaneously take the scholar course, the knight course, and the archduke candidate course. Unlike most students, he viewed the Royal Academy as a respite from his difficult life in Ehrenfest and stayed there year-round, only returning home when summoned.

During his school years, Ferdinand studied as a disciple of Professor Hirschur, an avid researcher of magic tools. He also became widely known among the other students for his skill in treasure-stealing ditter and harspiel, and routinely received the top grades in his class. After graduating from the Royal Academy, Ferdinand briefly served with the Ehrenfest Knight's Order, where he left a strong impression on the apprentice knight Damuel.

The death of the previous archduke increased Veronica’s power in Ehrenfest. When Ferdinand began to feel he was in danger of losing his life to her harassment, he followed Sylvester’s advice and joined the temple, giving up his status as a noble.

Not content with Ferdinand leaving noble society, Veronica used this opportunity to further harass him by taking away the cape in the duchy's colour that Ferdinand had received from his father at the gifting ceremony. Rather than making a completely new one, Ferdinand instead opted to use the blue cape he had won from the Dunkelfelger noble Heisshitze in a competition at the royal academy.

Initially, Ferdinand was bored with life in the temple and had little to occupy his time besides reading and research.

However, the civil war in the Sovereignty and subsequent political purges caused a serious mana shortage. Young blue priests and shrine maidens were called back into noble society, while those with enough mana were sent to the Sovereignty temple. Due to his mana and family status, Ferdinand was the only one left who was qualified to become the High Priest.
