In the year 2020, doors between two worlds began to open. Before we demons could consult the king about sending a explorer party to see beyond the doors, a group of strange creatures entered out world. They slaughtered a village claiming it was in the name of something called 'God'. We managed to hold them off but one escaped back to it's world. Soon after more of them came, which than sparked the Human War. A horrible fight against these strange creatures with weapons of destruction. For 5 years this conflict has been going on and for 5 years we have been losing many brave warriors.
