Exorcist Boy

A long time ago, the Millennium Earl wanted to occupy the earth, but someone used the power of God to eliminate the Millennium Earl and the world returned to peace, but the prophecy said: The Millennium Earl will come again... Now, the Millennium Earl once again turned the dead souls into demons in order to dominate the world, but the person who turned the dead souls into demons turned out to be the most important people of these dead. They did not intentionally turn their souls into demons, but they confusedly believed the words of the Millennium Earl, thinking that they could resurrect the dead. As a result, not only could they not be resurrected, but they also turned into foreign objects and became the weapons of the Millennium Earl, that is, "demons". But after someone discovered a stone box, everything changed. In order to deal with the devil, there are some messengers chosen by God who can destroy the structure of the devil. Their organization is called the "Black Order". The dark priests of the "Black Order" are called "exorcists". They have magical weapons that can defeat demons, and everything will be changed by them. They are the enemies of the Millennium Earl.
