gugumomu, I do not think the 3rd season will go to volume 14. Axctually i do not think it will reach up 13 volume as well since 13 and 14 volume have one arc basically.

I think 3 season will go between volumes 9-12 centuring mostly on 12....Why 12?

Its obvious as its based with random fanservice, no character development repetitive humor and is badly written (the last one is my personal opinion) without having much to do with actual plot... In other words - perfect for anime standards.

As for Henrietta... I do not think she will be the main boss but she could be the final one - the last obstacle specially if, as I think, Louise would leave together with Saito, she is unpredictable though, she might let them leave with good luck wish or might put them in prison like she did before... She is hard to predict but i do think she might be the last obstacle... Not saying that she will, but she does have the 'potential' so to say...
