I think it's said that she's beginning to feel numb/cold to certain things now.
oh .. damn mc going through a lot
It may also be that she overrides everything with her view and moral compass. The fact that she was so young kept throwing her off, then she was blaming the creator/author for making such a younger person capable of various forms of killing. It seemed as Hilda wanted to guard herself like she usually does, she’s only ok with a young demon passing messages and recruiting. I guess we’ll see how she continues to progress.
why is mc not shocked that rosie is a demon??? or is she dull to shocking things now
