Of Course the God of War Must Use Thermal Weapons

In the harem, there is no need for those who shoot guns. On the other side of the Atlantic, you can draw swords. My lord, times have changed.

When the continent collapses again and the world is on the verge of destruction, will anyone pick up the weapons in their hands again and fight to the death?
