Just watched the second episode and they really did a good job of adapting the light novels. I still don't like KugiRie voicing Agnese, but oh well.
I do think that they should have toned down the fanservice though. Heck, I don't even remember those scenes in the LN
s, but then again i read volume 7 a while ago...
Next episode: Amakusa Catholics in action! HELL YEAH!
