Different Demons Are Not Demons

Sometimes I wonder why there are distinctions between high and low for the same creatures, and why there are distinctions between humans and demons for the same humans. The noble paladins also have fallen demons, and the lowly demons also have swordsmanship geniuses. . . Could it be that only strong strength can make everyone shut up and block those who are talking? Can you prove your righteousness by being covered in blood? Or is kindness just a "gift" at the tip of the sword? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
