For where they had to end it I'm satisfied with that ending which surprised me. (Yes I know I'm a week and a half late. Between being sick, and working a lot I'm at least 2 episodes behind on everything I'm watching this season). I just kinda assumed they were gonna find some way to ruin it. Seems to happen more often than not. Still a lot to be resolved/explained like the witch, and potentially the other Sin Archbishops. I bought the first novel half way through the series, and am planning on buying the rest as they come out in English. This is one of the most interesting/entertaining stories I've seen in a while.
As far as best girls-
Beatrice (could potentially have been higher with more screen time)
