User blog comment:EmirK/Who do you want for the main antagonist in Toaru Kagaku no Accelerator?/@comment-265822-20131015020402

The only one from the list he is likely to come up against as an enemy is Kihara Gensei. The sounds of this first arc is that it is an original story so that's going to be an original character, The next arc would be the 930 incident so we know who the villain of that is. When we get to the brake down on his time with GROUP they only other original content would be between skill-out and Avignon or between Battle Royal and dragon for original enemies or Gensei deepening on his condition after the Railgun Daihasei Festival Arc. One last thing the only magic hes going to be fighting pre Gremlin is a group of random mages in Russia
