Misaka Mikoto, a middle-school girl with an amazing and highly-destructive ability to control electricity, is one of the top level espers in Academy City, a highly developed town populated by students with supernatural abilities. Joined by her three very different girl friends- her flirty roommate and skilled teleporting esper Kuroko; Kuroko's innocent rookie partner at the local student-run law enforcing agency Uiharu; and Uiharu's best friend Saten, who has no esper powers-Mikoto encounters various strange phenomena and eccentric people through her action-packed adventures in this exciting scientific town.

This hard hitting release from the girl-power sci-fi anime series Certain Scientific Railgun includes episodes 13-24 of the show, following the story of a girl named Misaka, whose psychic ability to manipulate electromagnetic waves makes her fit right in with all the other espers living in the futuristic Academy City, where other teenagers learn to master their powers for future careers in law enforcement, and try not to let their raging hormones get in the way.
