One day in the future, things will change. People from another world will come to the earth to merge the two worlds into one. The people from the other world in each region are different. Demons... Heaven... Dwarves... Humans with magic... They will lead the humans on earth to transfer to their own. In the world, some people have spread that the Demon King actually wants to go to the earth to find someone, so that the merger of the two worlds will happen. The humans on the earth, who have no power to restrain themselves, can only obey the people from the other world and come to the other world. The next step is for the humans to carve out a world for themselves...
