Kuroko, Uihara, etc. are all part of a quasi-student-council organization called "Judgement" who go around dealing with trouble makers. Because of the number of street punks this involves I feel like I'm watching a cop show.

In Railgun: Misaka, Kuroko, Uihara are the main characters. While in Index, Index and Touma are the main characters.

Both anime run parallel to each other.
