Erich von Rerugen is a talented military officer who serves under the Imperial General Staff. He was in the field up until he reached first lieutenant, and he also used to serve as a military attaché stationed in the Allied Kingdom.


In the light novel, he has short, brown, center part hair and blue eyes. He has a quite fit body shape, and the airs of a noble.

In the anime, he has black hair with a long strand of hair that set aside his face. He has a gentle, cool-headed looking face and wears bottom rimmed eyeglasses. He wears his officer attire in casual places and during conference meetings.


He is knowledgeable, diligent, and thoughtful on his duties. He has extraordinary observations of various departments during the War College conference and received high evaluations even in the General Staff. Hence, he is able to see through Tanya's true nature and thinks of her as a monster.[4]

But of all the people in the Empire, he is the one who trusts Tanya the most, supporting her requests for assaults to the point where he even fights Strategic command about it.


He first showed up as Chief of Decorations of Achievement Assessment Department in the Personnel Division and being the one to award Tanya the Silver Wings Assault Badge. Later, he was promoted from Major to Lieutenant Colonel due to his excellent performance, was assigned as a high-ranking staff officer in the Operations Division of General Staff, and went to the Northern Front for inspection. On the train to the north, he read Zettour's thesis about the Great War. He went to many battlefields to carry out the missions General Staff gave. In vol.1 ch.5, he attended the parade of the 203rd Aerial Mage Battalion as one of the inspecting officers and later took part in the Dacian War.

In vol.2 ch.4, he had a short meeting with Tanya and suggested that her battalion assists in an exercise of the North Sea Fleet.

On May 25, 1925, he visited the Secret V-1 Launch Base and had some discussion with Tanya. On June 20, he returned from the front lines after completing the inspection and was called by Rudersdorf.

On March 15, 1926, he welcomed the 203rd Mage Battalion's return from the Southern Continent and introduced an officer from Strategic Reconnaissance in Operations to her for a secret operation. Later that day, with the breakout of Russy invasion, he was busy with sending reserves and reinforcement to the front lines.

On April 10, he attended the court of inquiry about the raid of Moskva executed by the 203rd Mage Battalion. Later, at the end of the court, he beheld the fierce discussion between Tanya and Zettour.
