I think it is just like a game where you have an option to choose one, so you are given all of them from the start or choose one in the starting screen. So technically, she could focus on leveling up one Spirit root and still be able to rank up despite other Spirit roots only being able to rank up with all of their spirit roots evolved. Some game mechanics followed. I hope the convenient ones do follow to follow up on it.
Ahhhhh
