Ahaha, I can imagine people being unhappy about it. I always like to see MCs lose battles but win wars, especially when it's not about actual fighting. And this seems pretty realistic in a "your books don't work out" kind of IRL auditing you would expect. I guess the one thing is, with how insanely competent Shiki and crew seem to be, you'd think they would have already thought about this obvious flaw, but I guess you could also chalk it up to them not caring and knowing they could just pave all the capitals if they wanted to.
