The world is in danger again. But the scale of this game is not really that big, it is only contained in a village. Monsters have come and destroyed a village. Most of the people there have died. But there are still a large number of people who escaped from that disaster. Now, the player as a hero must stand up to fight. You are not alone in this battle. Players will be able to summon many different heroes. Idle Hero Wars is such a battle, such an attempt to survive.
