Yes. S1. Come on, with that kind of ending, a sequel is already confirmed. It’s like Shana all over again!
I still think J.C. Staff needs to improve on their pacing and exposition. From what I’ve heard, the original novels are chockful of interesting concepts and theories, but sadly enough, it didn’t translate too well to the anime. For a geek like me, all those magic and science stuff are really interesting on their own, so taking most of it out kinda saddens me, as well as making the show hard to watch. Anyways, what’s done is done.
On a sidenote… FUCK YEAH AYAKO KAWASUMI! It’s been seriously a loooooooong while since I’ve last heard her.
And FUCK YEAH RAILGUN ANIME!
