Well too late Eclipse, i followed Neosam advice and needless to say, i don't regret it at all.
I'd have never believed it would be this great. I thought before reading it that it was just going to be some good highschool comedy, not an amazingly awesome Sci-fi story!!!
I only read the first volume (i loved the ending), and i'm really curious to see how the anime turned out to be. The thing that i'm most curious (and worried) about is the fact that it's not in chronological order... wtf?!?
Anyway i can't wait to watch the anime, unfortunately it won't be anytime soon 'cause i'm moving and i won't have neither a computer nor internet at first

ps: anyone know the name of the fansub team who translated the books? 'cause they did a very good job to say the least
