On the surface, his piety and his faith are firm and pure. However, no one knows that his name is actually exactly the same as the legendary demon lord who plays with human desires in the legend on the thirteenth floor of the Demon Realm! The demon who charms the world is crazy because of him, the princess who respects all the people treasons because of him, the saint who serves the gods sinks because of him, and the holy and noble goddess falls because of him... When the cremation of faith becomes a prairie fire and the fire of sin is still burning, who can imagine that he was once just a simple and kind boy? There are thousands of temples on earth, only one who is worshipped by demons, believed by gods, and is eternal and immortal in the realm of gods and demons!
