Now that I think about it, this is the second time someone gets revived after a fatal wound has been inflicted
So what? You are going to find that the one who killed the demon king was not your daughter???
What are you going to do if you find out that the reason you were even able to see her was because of a resurrection spell?
Send the mage to jail for using forbidden magic after she saved the world?
Amazing work as always. Probably one of my favorite things of reading this series is how much you enjoy talking about it outside of just translating it.
