I've been using "Marry" up until now, but it just occurred to me that I don't know for sure if that's the best choice.
As I understand it, the spelling of her name varies a lot across translations. I've seen "Marry", "Mary", and "Marie" being used. Also, in Japanese, her given name is 茉莉, which I've seen get read as both まり and マリー.
So, is there a particular spelling that is more commonly used or more official than the others? Or are they about the same? How do the translators' choices for her name compare between the songs, the manga, the light novel, the anime, and other supplementary material?
