When his mother asked about the Demons, Rain couldn't help but sink into thought.
Demons? He knew of them from his Homeworld.
There were only two races in his world: Demons and Humans.
He had never delved deeply into the subject, but he didn't need to – due to the constant threat from Demons, almost everyone had a basic knowledge of them.
Demons are creatures that on an instinctive level hated humans, seeking to destroy them. It would not be an exaggeration to say that they were the main threat to humanity and the main incentive for its development.
When Rain began to spend a lot of time with Liliana Holystar, the Mother of the Hero in his World, his knowledge of Demons naturally grew broader, but in fact even with that he had no idea how, when, or where they came from.
And even in this world where there were many different races, including Elves, Dragons, and even the forbidden race of Angels, Demons were also present.
