Rinkah doesn't give good skills and Classes for her so pass, Nyx!Foleo is pretty good, Mozume!Seigbert is ok, Kinu's are good still think Azura or Setsuna are better for her Setsuna for Zero makes Eponine have the best speed.
good point Kinu has enough skill on her own also I think Sakura!Matoi is a great alternate for your mag asset you probably gonna have to A+ Syalla if you want Breaking Sky also Sakura's hair color is my second favorite for her almost matching her Canon hair color.
