agreed. this is really comedic, sure. but I have a hard time comprehending this to happen thanks to language difference. if it's between Yankee and Tommies (like during 1774 or 1812), I could see it happen.Only question is how did they mutually introduce themselves and then get confused if one speaks German and one speaks English? Wouldn't they have heard the other speaking a different language and realizing what's up immediately? (Also good to see more translation of this, it's such a good series and I hope the scanlations can go faster soon)
That, or everyone on the planet speaks Japanese. There's fair precedent for universal languages in isekai as well, though I don't know if that'd be what's going on in this particular alternate earthagreed. this is really comedic, sure. but I have a hard time comprehending this to happen thanks to language difference. if it's between Yankee and Tommies (like during 1774 or 1812), I could see it happen.
my best guess is German and English aren't really that different, and sandstorm help give both side excuse to not listening clearly (thus fill in the blank with language they do know).
but then again... this is Isekai, thus we could conclude that German and English here sound more similar to each other than they do in our world.
