Hahaha. The original reason I watched this series is basically insane. About 3 years ago, a video called 'top 50 anime openings' (or something along those lines) suddenly appeared on my youtube suggestions page. I had never watched anime before, nor did I have any idea what anime was, so I had no idea why that was there. Nevertheless, I watched the thing because I had way too much time on my hands. At #1 was Masterpiece (the second opening of the first season). For the sole reason of liking the song and what I saw in the video I decided to look this series up on wikipedia. Because the premise seemed quite amazing to me, I searched for it online and, albeit reluctantly at first, I watched it in Japanese, which at the time sound like gibberish to me, a non-anime watcher. The series quickly grew on me, and after the Sisters Arc I was completly hooked, constantly praying for Accelerator to appear. To this day I am a huge fan of the guy. I was thoroughly disappointed when season 2 ended on such a cliffhanger, but last May I received an e-reader. I got around to downloading all the novels, and in a time period of about 10 months I read all of it.

Basically, the fact that Masterpiece was #1 threw me into the world of Raildex and anime in general. Thanks, random video poster!
