Demons.
Everyone knew what those words meant, but did they exist?
That was a question very few could answer.
No. It would be better to say that everyone could give an answer, but only a few knew the right answer.
Raven, who knew the plot, happened to know more about demons than anyone else.
After all, the 'Raven Tale' novel focused on fighting demons.
From the first trial to the part Raven had read, the demons were the main villains.
They were so strong that the weakest of them was as strong as a plate-six magic swordsman.
Unlike corrupt beasts, who could kill with corrupt poison, the demons were different.
They could turn others into demons and control them.
Worse, they loved everything evil.
They were truly evil, unlike the corrupt beasts that the Vaise family dealt with.
