Misaka, one of the the 7 strongest people at her school, is the titular character of the story and can control the electric fields surrounding her. She lives in Academy City, a "scientific city of the future" of over 2 million students all learning to control their esper (supernatural) powers -- of which some are more powerful than others. She mostly tries to do the right thing but isn't above taking matters in her own hands and bending a few rules here and there. This is about her trials, tribulations, and experiences as she grows up surrounded by her friends. This story deals with "Level Upper", a cheat people can use to quickly become more powerful without effort.

Toaru Kagaku no Railgun is a fully formed 'side-story' to Toaru Majutsu no Index where a supporting character there (Misaka) is given her own complete story and viewpoint while also interacting with the concurrent events of Index 1.

This is the second story in the entire overarching story line -- you should watch Index 1 first, but you MUST watch this before Reilgun S (aka Railgun 2).

富士电视台于2003年1月6日开播。由COWBOY BEBOP的幕后班底制作，曾担任《新世纪福音战士》设计和大友克洋的《MEMORIES》中《最臭兵器》导演的冈村天斋执导。画面制作非常精良，菅野洋子做的音乐也很棒，个人认为应该算2003年最好的动画之一。
