Mikoto Misaka vs. AIM Burst

Sorry, no subtitles at least for the time being. In this clip, our heroine takes on the massive, seemingly unstoppable manifestation of AIM Burst that threatens Academy City's nuclear reactor. Much of the dialog has been removed from this clip to focus on the action in the episode, namely Mikoto taking on a monster several hundred times her size. [contains portions of A Certain Scientific Railgun episode 12, "AIM Burst."]
