DXD: The Zombie Army

throughout or around 1942, Nazi scientists throughout Europe created a "Weapon" called Project Necromancer, or Projekt Nekromant in German. They apply it to Mikhail Eastwood, a young Jewish boy who is Patient 13225. They were not aware, however, that they had given him skills that would bring down the Reich. A bridge is destroyed by the Germans after he had murdered everyone within the facility. But after a year, several people disappeared. As a result, a few Devils arrived, but Mikhail is not the type of person to welcome guests to the deserted military station.
