I was about to post on the other thread when a little back tracking reveals that there's already a thread for this
I've just read the first three english chap scans of the main series, tried looking for more, but ended up with
A Certain Scientific Railgun instead
(Gotta love the titles...)
I've just finished one and a half volume, meaning 11 chapters, and it's definitely a more interesting story... Well, it's not really fair to compare it with only 3 chapters
The story runs some what parallel to the Toaru Majutsu no Index right? Considering the occasional appears of Touma, who just knows how to push Makoto's buttons without even trying
Heck, if I'm not wrong, she disappeared for 3 whole chapters just to hunt him down
