Tanya von Degrechow is a senior commander in the Imperial Army of the Fatherland. She has blonde hair, blue eyes, and skin that is nearly transparent. She is admired and feared by both allies and adversaries because to her ruthlessness on the battlefield. But she is only a young girl of nine years old, despite her prominent status. The protagonist, who was once a common merchant from the actual Japan, was picked by a supernatural being and reborn in an alternate early 20th-century Europe where magic plays a significant role in combat.
As a loyal, command-oriented businessman who prioritizes law and order above all things, he realizes his new fate only unwillingly. He prefers to settle disputes matter-of-factly and verbally. Tanya continues the fight against the enemies of the country and, along the way, her own personal one against the creature X who put her in this predicament in the first place with the hope of one day leading a calm life away from the front lines.
