A less OP, more creepy Rimruru? Its got cute elf girls at least.
Its actually exactly what the translation is! her abilities dont define what she wants to be: a king of a country that she was once part of. (I read the web novel) so the enlight of <king> is the perfect translation. Just like the enlight of <magic> isn t about casting spells. Its kind of a word play with being enlightened on the path of a king or magic or alchemy...The knowledge of "king" is a poor translation.
it's basically leadership/ruling skills as the daughter who is the " king " student is a leader of a country IIRC.
Also, all the daughters are adopted... so it's slightly less creepy then it looks for him to ride on her boobs. ( all daughters are also different races )
The MC was not your stereotypical bard who tapped every booty he could find... as fun as that would have been.
