Gods and Demons that made Humans

After the Second Great War, humans began to rebuild their communities and erect new cities around the world. However, after 300 years of living in prosperity, the revival of a new demon king had been felt and the southern part of the continent was filled with demonic creatures. A proclamation coming from the heavens told the humans to prepare themselves to a defeat the demon king to prevent another great war. Humans quickly armed themselves with sword, shields, and staffs to prepare to defend themselves as soon as the new heroes rise upon to defeat the demon king.
