Doing a search of the forums, I came across this old one.
If you ever get a chance, try and get a read of the light novel, which shockingly...has not appeared to be licensed.....someone probably should create a suggestion topic.
But I hope now that the series is completed you managed to enjoy it, the ending being anime original compared to the source, which I am of two minds whether it is better or worse.
Also do not forget to watch the movie if you have a chance. I have watched it in both native and dub, both to my enjoyment.
