They are the dark priests of the Black Order, exorcists with supernatural powers...
A long time ago, the Millennium Earl once wanted to occupy the earth, but someone used the power of God to destroy the Millennium Earl and the world returned to peace. However, 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 was actually its most important person! They did not deliberately turn their souls into demons, but they were confused and believed the words of the Millennium Earl, thinking that they could resurrect the dead. ——However, not only can they not be resurrected, but they can also be turned into demons and weapons of the Millennium Earl... That is - "? Consumption A?!"
After someone discovered a stone chest, everything changed!
To deal with demons, there are some messengers chosen by God who can destroy demons. Their organization is the "Black Order"! The dark priests of the "Black Order" are called - "Exorcist Boys"... They have supernatural weapons to defeat demons, and everything will be changed by them... They are the nemesis of the Millennium Earl.
