Dakkodango Translations

I'm battle the first dragon atm, so I have one question, does the language that people speaking turn into japanese at some point in the game or will it be some weird language forever?

It reverts to japanese eventually. Not quite sure when exactly. I'd like to think of it as Yuuto learning the language to an extent he can use it just as fluently as Japanese. Therefore it's as if everyone is speaking his home language.

I think it changes at the end of chapter 1 but not sure. Anyone wanna confirm when it switches?

thanks for the replies, I was just about to give up on the game due to a certain character's uncontrollable behavior and weird language.

Guess I will turn off voice until chapter 1 ends.
