Ah, all right. Yes, that part is machine-translated.
You can find the german and other language-scripts in the game folder>src>language>dt.txt
I've fixed some things on the latest dt.txt-file and will upload it, you should work from this on. As for the new character Cynthia; I've only changed the first few lines of <u6own> and <ev13>.
I'm curious how you'll make it sound. However, you should try to keep Nene's language similar to the rest of the game.
From what it seems you'll also have to copy Teala's lines, which are all u16+ev12 lines, from another language file into the dt.txt; that is, if you want to translate that part as well.
Some lines might have to be translated directly from japanese, as the english translation is faulty at times.
Oh, and leave a small hint here once you are starting to work on it, because then I won't continue and we avoid double work.
