Apparently since 5.3 in the Japanese version of the game, both Alisaie and our character have been addressing G'raha casually as "Raha", indicating a close relationship with him.

We have seen other characters do this – Krile calls him Raha, and in other cases we've seen Matoya refer to "Shtola" and Lyse to "Naago" without the tribe prefixes for the same reason – so the audience is already familiar with the idea that this is done for close friends and relatives.

Why was the decision made to alter it in this case and lose the implications it has on the characters' relationships?
