Steel Vampire

Five hundred years of peace. No war, no disease, no poverty — humanity achieved all of it. Then flying objects called Steel Vampires appeared and began threatening the survival of the species. With extinction approaching, military planners remember one name: Yoshino Sakurajima, a man deemed too dangerous to the peace to remain active, who was cryogenically frozen and erased from the historical record. He is thawed. The Steel Vampires have no idea what is coming.
