Steel Vampire

Hear the shrieks of colliding metal! Behold the true form of steel! An explosive onslaught of shooting action!!

Five hundred years had passed since the last war. Humanity succeeded in eliminating all forms of war, disease, and poverty, bringing about an era of perpetual peace. However, calamity soon struck. The sudden arrival of flying objects known as Steel Vampires threatened the entirety of mankind's existence. On the brink of extinction, the fate of mankind has been left to just a single person. A man deemed far too dangerous to the sustainment of humanity's serenity. He was cryogenically frozen--his existence nearly erased from history. His name is... Yoshino Sakurajima.
