Isn't grom stated to be relative in strength with the previous demon lord? Then how come he's not obliterating luciana? They're even at a tie instead of a 1 sided beat down (luciana even said that grom is still far from the demon lord in terms of power)
@Diamondmya25 by "he" who do you mean? Grom? What my original comment was that grom is supposed to be much stronger than luciana (grom=previous demon lord, luciana < previous demon lord) so how does "he" is getting stronger have to do with anything?
Most definitely he couldnt raise her for two reasons, one being she didnt have any lingering regrets or resentment and, this would probably be a good plot twist, she reincarnated to become the hero again. She will be the one to subjugate him.
