>>47315424idk if sharing the exact same language would be good lore, as I doubt you want to be directly related to us, but same language family or dialect or whatever makes sense could work. I just would not like you to have «Tsukigo» as your tongue since it makes it seem like /indie/ is just part of nijisanji which is completely false. Maybe even the languages are the same but you use different word to describe it as the indie thread you are and we use our word to describe it. Sort of a pride issue? It could develop that both tongues were the same at one point but have minor differences now because of that pride? Much depends on how you wish to do your history, and i am open to all things here.
