Description
Berkman is a major antagonist in the anime Izetta: The Last Witch, serving as a high-ranking intelligence officer for the imperialist nation of Germania. His official rank is Major, and he is portrayed as a cunning, pragmatic, and highly competent spymaster who is deeply skeptical of miracles and propaganda.

In terms of background, Berkman is a special agency officer for the Germanian Empire. His role places him at the forefront of the empire's efforts to counter the magical threat posed by Izetta, the last witch who fights for the small duchy of Eylstadt. He is a key figure in the Germanian military and intelligence apparatus, working directly under the Emperor and interacting with top officials like the head of the Weapons Design Division.

Personality wise, Berkman is defined by his analytical and cynical nature. Unlike many of his superiors who may be driven by ideology or ambition, Berkman approaches the war as a problem to be solved with logic and strategy. He is perpetually calm and calculating, often seen with a knowing smirk that suggests he is always several steps ahead of his opponents. He does not believe in superstition and is quick to identify the limits of Izetta's power, correctly deducing that a witch capable of single-handedly winning the war would have allowed her kind to rule the world long ago. This rational mindset makes him a formidable adversary, as he focuses on finding practical countermeasures rather than simply fearing the enemy's magical advantage. Berkman is also highly self-serving, a trait that ultimately dictates his actions when the tide of war turns against Germania.

Berkman's primary motivation is the success of the Germanian war effort, though this loyalty is ultimately conditional. He dedicates himself to neutralizing Izetta as a threat, developing counter-propaganda and military strategies to break the symbol of hope she represents. He is instrumental in engineering situations to test Izetta's power and find her weaknesses. However, his service to the empire is not born of fanatical devotion. When Emperor Otto becomes overconfident in his new magical weapons and begins to sideline Berkman for being too effective, Berkman shows no hesitation in abandoning the sinking ship to save himself.

Berkman's role in the story is that of the primary human antagonist and strategist for Germania. He is the architect of the empire's anti-witch operations, contrasting with Eylstadt's own strategists like Sieghard Müller. While other characters may wield magical power or command vast armies, Berkman fights the war with information, deception, and ruthless pragmatism. He is present at key diplomatic events, such as a masquerade ball in Britannia, where he demonstrates his audacity by confronting the protagonists on neutral ground. His investigations and schemes directly challenge Finé and Izetta's efforts, making him a constant source of tension and conflict.

Regarding key relationships, Berkman works closely with several subordinates and allies. His aide, Lieutenant Rickert, is a loyal and capable soldier who serves as a sounding board for Berkman's plans and carries out sensitive missions, including a dangerous parachute drop into enemy territory to gather intelligence. Berkman also has a significant relationship with Captain Basler, a Germanian pilot. He summons Basler to assist in the hunt for Izetta and later shares sensitive information with him about his falling out with the Emperor, indicating a degree of trust, though their relationship ultimately ends in confrontation when Basler accuses Berkman of caring only for himself. His most notable counterpart on the opposing side is Sieghard Müller, Eylstadt's spymaster. The two engage in an intellectual battle of wits, with each trying to outmaneuver the other in the shadow war of propaganda and espionage.

Berkman undergoes a notable development over the course of the series. Initially a loyal and effective servant of the Germanian Empire, his success becomes his undoing. After leading the charge against Izetta and helping secure numerous victories, the Emperor fires him, believing Berkman to be a liability due to his competence. This betrayal severs his loyalty to Germania. In the final episodes, Berkman surrenders to the Eylstadt forces, offering crucial intelligence about the empire's final offensive in exchange for his own safety. He survives the war, and in the aftermath, he is seen in New York City turning over a briefcase of documents to agents from the United States of Atlanta, proving he has successfully transitioned to a new life by selling his knowledge to the highest bidder.

Berkman does not possess any magical abilities or superhuman combat skills. His abilities are entirely mental and tactical. He is an expert strategist, master manipulator, and skilled intelligence operative. His greatest talent is his analytical mind, which allows him to see through the deception of the Eylstadt leadership. While others are awed by Izetta's power, Berkman systematically tests her, identifies her limitations, and develops effective counter-strategies, making him a dangerous foe despite having no supernatural powers of his own.
