During the war between humans and demons, the superior gods stopped this war that mankind would lose. The two tribes signed a peace treaty. After the demons left, the gods gave humans the power to compete with the demons.
In order to prevent the demons from breaking the treaty, humans have established seven academies, namely: Basic Academy, Swordsman Academy, Magic Academy, Archery Academy, Healing Academy, Assassin Academy and the Saint Academy with the power of God...
Intention: Relying on the power of others will eventually be taken back.
