When using a Fantasia on one of my retainers, as I began to enter into the re-customization screen, I got a notice that said I can change my Retainer's nickname, or have them visit the Aesthetician at any time, however, no matter where I look, nor what I google, I simply cannot find an answer as to HOW to actually do this. I've even contacted support, but they tell me that a Game Master cannot help with In-Game activities, which is ironic, because why are they called Game Masters if they don't help with the game?

So I come to you, Forums, for assistance. Are we just being lied to by the game itself? or am I missing something somewhere?
