Actually, the character that worried me the most was Amuria and her "Motto tsuyoku!" stuff. After the fourth time I heard her say that, all kinds of horrible were going through my head about this series turning into Gundam with lesbians.
I know now that pretty much everything I just said was wrong, but I actually almost dropped the show then because of that. Fortunately, episode two and Erii came along to save the day. That's when I knew I found something worth finding.
I always liked Aaeru. I picked up early on that she wasn't that typical upstart that everyone else was talking about. And her blatant honesty was just awesome from the very beginning.
