It was told out of sequence which is fine, but the story that takes the 4th and 5th Volume to tell would have been better at the start. A more linear story and maybe not as action packed but it would served the manga better. Anyway, there's a sequel isn't there?
I liked it a lot actually, I'd rather it ended where it did rather than Jill and the team to tackle them taking on the conspiracy of the Cathedral head on and rushing it.
