@SatouPendragonlvl313 I think that title just means she's the back-up plan for the four heavenly kings. If they die, she does the job instead (she is rather good at magic afterall)
I guess most of the other worlders must have been mangadex commenters.
But in all seriousness, I kinda hope the kid isn't dead, it was a bit too early I think. It would have been nice to have him join hanbin's ever growing family, but if he died then it would be quite a downer to see hanbin...
