Intro
It was the moment the bells of the Lumina Cathedral rang.
A black crack suddenly appeared in the center of the cathedral, which had been filled with pure white light.
Thump—.
Red flames flared up, and silver moonlight flowed out. Blue lightning grazed the floor, and red rose petals drifted through the air. Finally, a cold frost covered the cathedral floor in white.
And there, five men revealed themselves.
The humans gasped.
The Kings of the Demon Realm.
It was the first time in history that the five Demon Kings, who ruled different territories, appeared in the human world at the same time.
