Meet Mikoto Misaka, the third most powerful Level 5 esper in Academy City. Together with her best friend Kuroko Shirai and the other members of Judgment, a student-run law enforcement agency, Mikoto delves deep into the dark heart of the scientific sprawl she calls home and uncovers secrets she wishes she hadn't! A Certain Scientific Accelerator is a must-have manga series for fans of stories that blend science and magic like Psychic Academy and Full Metal Alchemist. The Certain franchise began with the long-running light novel series A Certain Magical index, which was adapted into both a manga and an anime series. lts spin-off, A Certain Scientific Railgun, became a breakout hit with a better selling manga and higher rated anime series. In October 2010, a new anime series following the further adventures of both series' protagonists began airing in Japan. A second season of the TV anime A Certain Scientific Railgun began airing in Japan in 2013.
