[@BurningDaisies] Still not sure yet, I usually decide on the spot when making a CS.

I think my Nohr Twin would be a butler. My Hoshido Twin (Mechanist or Onmyoji) would probably be a retainer to my Hoshido Sibling. My Hoshido sibling would be Falcon Knight. My other retainer for her (aside from my Hoshido Twin) will probably be Swordmaster. I'm also thinking about making a Nohrian Dark Knight or Adventurer as a side role. It's hard to say though.
