Pretty sure Caeldori is pronounced kyle-dori. Cael in latin means sky/heaven/air, dori just sounds kinda Japanese I guess. Fits better than Rhajat, but there wasn't much hope with that one.
I don't exactly trust kotaku, but if it really is removed they should lower the price or something since they took a chunk out of the game. As small a feature as it is, I still don't want to pay full price for less game than Japan got.
It's in the text dump that was datamined. In the ending section it literally says 同性婚 (gay marriage) for an S support for male Kamui and Zero and female Kamui and Shara and mentions that they adopted children.
