Description
Comte de Guercy is a significant secondary character who serves as the French ambassador to London. He is a former member of Le Secret du Roi, the king's secret intelligence service, and in this capacity had a prior association with Lia de Beaumont, the sister of the protagonist D'Eon. His position as ambassador places him at the center of Franco-British diplomatic affairs during a volatile period.

In terms of personality, Guercy is primarily characterized by his pragmatism and self-interest. He is a man whose loyalty is ultimately controlled by money rather than any sense of national pride or personal honor. This mercenary quality makes him an unpredictable and unreliable ally, as his actions are consistently guided by what is most financially advantageous for him. He presents a polished, diplomatic facade but operates from a foundation of personal avarice.

Guercy's primary role in the story is as a contact and temporary ally for D'Eon and his companions when they arrive in London to pursue the Royal Psalms and counter the machinations of the poet Maximilien Robespierre. The protagonists seek out his aid due to his past connections to Le Secret du Roi and his former association with Lia. However, this assistance is conditional and reveals his true nature. While he helps with their investigation, he betrays their trust when circumstances become precarious, demonstrating that his support cannot be relied upon in the face of personal risk or superior offers.

His most important relationship is with D'Eon, which is based on a potent mix of professional rivalry and mutual suspicion. This dynamic is grounded in historical events, as the conflict between D'Eon and Comte de Guercy over the position of French ambassador was a famous public scandal. Historically, after Chevalier D'Eon successfully negotiated a favorable treaty, King Louis XV appointed Guercy as ambassador instead, leading to immediate and intense animosity between the two men. The anime incorporates this background, establishing a pre-existing enmity that shapes their tense interactions. Guercy's role also connects him to the late Lia de Beaumont, as they were both members of the same secret network.

Regarding his development, Guercy does not undergo a significant moral transformation. His character remains consistent as a figure motivated by personal gain. He is an obstacle and a mirror for D'Eon, representing the corrupting influence of political power and financial greed that contrasts with the protagonist's often more idealistic or haunted pursuit of justice. His actions serve to complicate the protagonists' mission and deepen the intrigue in London.

In terms of abilities, Comte de Guercy is not depicted as a physical combatant or a wielder of the mystical Psalms. His notable abilities lie entirely within the realm of political and social maneuvering. He wields the authority of his official ambassadorial position and uses his diplomatic skills to navigate dangerous situations, though his main strength is his wealth, which he uses as a tool to secure his position and influence outcomes in his favor. His design in the series is noted to be inspired by the appearance of the modern actor Jack Black.
