A Scientific Railgun 

An anime series. Better known as To Aru Kagaku no Railgun (とある科学の超電磁砲＜レールガン＞ / "To Aru Kagaku no Reerugan"). A side story of To Aru Majutsu no Index (とある魔術の禁書目録＜インデックス＞ / "To Aru Majutsu no Indekkusu"). This side series is focused on another main character, Mikoto Misaka (御坂美琴 / "Misaka Mikoto"), a Level 5 esper, nicknamed "Railgun" because of her ability to manipulate electricity, to allow the use of a special move that allows her to fire a projectile at several times the speed of sound. This "move" is similar to a actual railgun, a experimental Navy weapon which fires a projectile using electromagnetic force.

Hey, did you see "A Scientific Railgun"?

No, why?

It's good! Should try it, though.
