Adelheid von Schugel is the Empire's Chief Engineer for military research and development, responsible for significantly advancing the Empire's magical technology beyond other nations. His key inventions include the Elinium Type-95 Operation Orb, the Type-97 Maneuver Assault Orb, and the V-1 hydrogen-fueled rocket, crucial to Operation Shock and Awe. During the war, he appears as a man in his fifties, typically wearing a white lab coat and a monocle over his right eye. Anime depictions show him with curly dark hair, a slouching posture, and eyes asymmetrical due to the monocle. Approximately forty years post-war, he is elderly, sporting long hair and a beard, using a walking stick, and dressed in civilian suits and hats. His personality blends genius with instability, earning him the military nickname "Walking Disaster." He prioritizes theoretical perfection over practical safety, considering test personnel expendable. A divine epiphany caused by an entity called Being X triggers a profound religious transformation. This experience solidifies his belief in miracles and divine intervention, leading him to defy military orders halting his projects. He declares willingness to die as a martyr, framing his engineering as an act of faith. Key background events include the near-failure of the Type-95 project due to impracticality. Facing suspension and funding loss, he conducted an unauthorized high-risk test using Tanya von Degurechaff. The orb stabilized only after Being X's direct interference, which he attributed to divine will. He later supplied Type-97 orbs to Tanya's battalion for field testing, interpreting their collaboration as divinely orchestrated. Post-war, he emigrated to the United Kingdom of Albion and became a priest. In this role, he retrospectively explains the Empire's wartime actions as a reaction to other nations' fear of its power. His relationship with Tanya is adversarial; he disregards her safety concerns and uses military authority to compel her participation in dangerous tests. He maintains unwavering devotion to Being X, crediting all successes to divine influence.
