Description
Count Volger is a central supporting character in the anime Leviathan, serving as the fencing instructor, strategist, and primary guardian to the young prince Aleksandar von Hohenberg. He is a man of aristocratic bearing, tall and distinguished with a signature thick gray mustache, and he typically dresses in military-style uniforms that reflect his background as a former cavalry officer. His entire life and identity are bound to the service of the Austro-Hungarian Empire and the House of Hohenberg, a loyalty that defines his every action throughout the series.

In terms of personality, Volger initially presents as haughty, pragmatic, and no-nonsense. He possesses a sharp, analytical mind and a dry, often sarcastic wit, which he frequently directs at Alek as a means of both instruction and criticism. He is a man who values efficiency above all else and can be ruthlessly pragmatic, a trait demonstrated early on when he does not hesitate to drug the panicking Alek to ensure their escape from Austria. Underlying this cold exterior, however, is a profound sense of honor and deep-seated loyalty to Alek and the memory of his father, Archduke Franz Ferdinand, whom Volger counted as a close personal friend. Volger's worldview is strongly tied to the traditions of the old empire; he tends to look down on commoners and is unaccustomed to physical labor, yet he willingly sacrifices his comfort and station to keep the young prince safe.

Volger's primary motivation is the preservation of the Austro-Hungarian legacy through Prince Aleksandar. He was a key figure in a secret plan orchestrated with the Archduke to change the terms of Alek’s parents’ marriage, thereby securing the boy’s status as a true heir to the throne. To protect this secret and Alek from political enemies, he orchestrates the prince's flight from the palace on the night of the Archduke's assassination. His role in the story is that of a master strategist and moral compass, though one whose morality is inextricably linked to nationalism and the interests of his empire. Aboard the airship Leviathan, he often acts as the de facto leader of the Austrian contingent, using his cunning to navigate the complex political and social dynamics with the British Darwinists. He is quick to see through deception, famously being one of the first characters to deduce that the young midshipman Deryn Sharp is, in fact, a girl in disguise.

Throughout the narrative, Volger’s relationship with Alek is the most significant. While he is genuinely fond of the boy and concerned for his welfare, he maintains a formal and often critical distance, refusing to coddle him and insisting that politics and statecraft are Alek's birthright. Alek often looks to Volger as a father figure, though Volger himself seems oblivious to this emotional dependency. His relationship with Deryn Sharp is far more adversarial; upon discovering her secret, he views it as a tactical advantage and attempts to use it to blackmail her into furthering his own plans, demonstrating his willingness to manipulate anyone to protect Alek’s interests.
