A few weeks before the war began, he and Major Reiter go to Major Magatsu to form a new alliance between the Third Reich and Imperial Japan for the Holy Grail War. In exchange for a hiding place within the imperial capital, they ask that Major Magatsu summon a Berserker-Class Servant, and they will provide him with the IV-Type Heroic Spirit Restraining Device (IV型英霊拘束具?) so that he can control his Servant. When Magatsu asks why they would give him this, he answers that "those with power will always gain more power."
His side profile seems to indicate he wears an eyepatch over his left eye.
He is seen from the back, with his face hidden, while Major Reiter reports to him the loss of one of their Gertkrieger prototypes and the beginning of the Imperial Capital Holy Grail Strange Story.
