Man, the translation is rough, but what's worse is that lines are not always in their corresponding text boxes

This time on page 27. The part after "Dungeon he said?!" is swapped with Natsukawa's words in second panel (though, they are hard to decipher anyway). Then, MC's words are from the previous page, and instead it should've been something like "Would it be okay with such a number of people?"
Also, can't say i understood a single line in the dialog between MC and Kai, but i guess it boiled down to the fact that Kai was trying to tell that MC's sis is worried about him in her own way?
