Description
Anson Sue, also known as Anson Sioux, is a character from the military fantasy series Saga of Tanya the Evil. He serves as a field-grade officer and the commanding officer of the Legadonia Entente Alliance's 5th Air Mage Battalion.

His background is that of a professional soldier driven by a deep sense of duty to his homeland. He holds the rank of Colonel and is a family man, with a wife and a daughter named Mary Sue. In his first appearance, he leads his battalion during the Norden Incident, where they engage in combat with the Empire's mage observer, Tanya Degurechaff.

In terms of personality, Anson Sue is characterized as a loyal soldier who cares deeply for his country, his comrades, and his family. This loyalty is his defining trait, and the trauma of losing many of his men in combat against Tanya weighs heavily on him. He is depicted as a competent and sharp commander, as seen during the Battle of Osfjord, where he is able to deduce the enemy's intentions and deploy his mage battalion effectively. His love for his family is demonstrated in a poignant farewell scene at Port Arnelus, where he sends his wife and daughter to safety in the United States, choosing to remain behind as a soldier to escort the government into exile. During this farewell, he receives a submachine gun from his daughter as a Christmas present, a gift that becomes a significant personal symbol for him.

Anson Sue's primary motivation evolves over the course of the story. Initially, his actions are driven by a straightforward desire to defend the Legadonia Entente Alliance from the Empire's aggression. However, after his unit suffers devastating losses at the hands of Tanya and witnesses the fall of his country, his motivation transforms into a personal vendetta. He becomes singularly focused on revenge, seeking to destroy Tanya, whom he views as the Devil of the Rhine responsible for his nation's downfall and the deaths of his soldiers. This quest for revenge ultimately consumes him, as he neglects to contact his family in favor of preparing to kill Tanya.

His role in the story is that of a recurring antagonist and a direct foil to the protagonist, Tanya Degurechaff. He is the first significant enemy mage commander she faces in combat. Their repeated clashes serve to highlight the human cost of Tanya's ruthless efficiency and the war itself. More importantly, his fate serves as the primary catalyst for the introduction of another key character: his daughter, Mary Sue. His death at Tanya's hands directly motivates Mary to become a powerful enemy of the Empire, ensuring that the consequences of his personal war continue to resonate throughout the narrative.

Key relationships for Anson Sue include his bond with his daughter, Mary Sue, which is the most significant personal connection in his life. His farewell to her and his subsequent death are the driving forces behind her character arc. His relationship with Tanya Degurechaff is purely adversarial, defined by a deep personal hatred born from combat. He bitterly refers to her not by her feared nickname, the White Silver, but as the Rusted Silver, a commentary on the blood of his countrymen he believes stains her reputation.

In terms of character development, Anson Sue transitions from a conventional, duty-bound military officer to a man driven by divine intervention and a thirst for revenge. After being mortally wounded by Tanya during the Battle of Osfjord, he is rescued and survives. In the anime adaptation, this event leads to a supernatural development. He reveals that he has been contacted by a divine entity, referred to as Being X, which has bestowed upon him special powers to destroy the Devil of the Rhine, Tanya. This marks a stark shift in his character, as he becomes a divinely-empowered agent of vengeance rather than merely a soldier.

Anson Sue possesses notable abilities as a mage. He is a highly skilled and accurate aerial mage, with a reputation for having a greater grasp of accuracy than Tanya, able to engage targets from outside their visual range. He can magically enhance his bullets for increased damage. In a notable instance, he uses this ability on a trench gun to fire a spread of magical explosive shots, an action noted as a treaty violation. In the anime, he receives a unique blessing from Being X, similar to Tanya's powers. This blessing allows him to achieve a high level of power output without the need for a specialized computation orb like the Elenium Type-95, and it is activated through prayer. This power manifests as a glowing yellow energy in his eye and allows him to enchant his bullets individually with devastating effect. His journey ends in a final battle against Tanya, where he is ultimately defeated; in the anime, he is shown blowing himself up in a desperate final attempt to kill her.
