There's one thing that bugs me about it. The heroine of the series was the victim of a very nasty organisation. Through an unlikely series of events
So the head of the organisation is heart stricken about the things his organisation had done to the heroine of the story and yet he doesn't show the slightest bit of regret about all the other people treated the same way as her. And nobody else seems to be bothered about that either. For all we know they could be busy bringing up another 'class' in the same way as the one she was in. :@
This anime has all sorts of supposedly moral themes and yet this glaring inconsistency runs right through it (well, as far as the first 20 episodes anyway).
Anyway that is the end of my rant, now I've got that off my chest I'll get back to more useful stuff instead.
