The Kingdom of Erebos is ruled by a King named Kyros.
Thirteen years have passed since the end of the war against the Demon King. Kyros's father died along with other kings of each land due to fighting.
So in Kyros's eyes, all other kingdoms are weak and incapable of fighting the demons. One day, King Kyros received a letter from the land of Luxians, a letter that contained an invitation for an Alliance of kingdoms to prepare to fight the demons again, but he rejected it.
Now his kingdom is strong and capable of fighting the demons alone. And he also thought that in order to further strengthen his kingdom, instead of making friends, he should conquer other kingdoms and seize their power. King Kyros has a plan to seize the power of other kingdoms
