Amon had gotten a lot of trouble in order to be able to go back and look for Diana. That was especially so due to the fact that within the nation that Diana was currently located in, all the members of the other races had been eliminated completely.
It was all due to luck that he had been able to survive until today. Had it not been for the fact that he did not try to confront the humans directly, but instead, he hid whenever he encountered them, he would have already been killed by now.
It might be true that he usually looked down upon the humans as an inferior race, but at this moment, with the power that they possessed, it was definitely impossible for him to be able to look down upon them.
