I've looked everywhere and I can't seem to get a definitive answer. Also have all the light novels been translated to english? If so can I buy them somewhere on the internet or do I have to download them in pdf form. Finally, could someone explain to me briefly what the continuity of the whole franchise is? Im not sure I understand the whole 16.5 stuff and all that. Any help is much appreciated!
