The man said: "Indeed that was my mistake, if I knew that you would become a demon warrior I would have kill you right away."
Celia was puzzled she asked that man: "What do you mean by demon warrior?"
The man snorted and said: "So ignorant, let me tell you this and afterwards I will kill you all, there are four type of demons, low demon, demon, demon warrior and demon god, the so called demons king is just a trash who has been choosen by my goddess to govern Inferno, he is just a tool nothing more.
But a demon warrior that's another story, your father had been the last one in more than a hundred thousand years, he chose to betray us that's why he had to die but you can still join us. We will spare your brothers if you choose to join us, think carefully."
