@Scrabbleman She is really really OP, she even has S-rank swordsmanship, but her sword probably broke because it wasn't great, S-rank monsters probably can't be cut with your average iron or steel sword. The MC gave her double growth rate and double skill points when she was lv1 and she has to be at least lv60 by now, so she probably has some more insane skills now too. Her unique skill was called Cut Marks but I don't think it has said what that skill does yet.
