Maybe I help to answer, if you look the source for this page http://www.aikatsu.net/character/index.html the Rei image name was bt_rey, that's why when that page revealed we assume Rei name is Rey since the Rei's profile page not yet to be made that time and just made two days ago reveal the official name is Rei.
