That's why I hate Nakagami Armor. It's a literal counter to every single possible enemy in a world of magic save maybe the demons. And the fact that its ability to "break the laws of magic" is vague enough that it could be used in any situation yet it isn't. The fact that it's owned by Erza only makes things worse. I wonder if she can kill Zeref with it.
