A Certain Magical Index aka Toaru Majutsu no Indekkusu is a Japanese light novel series written by Kazuma Kamachi and illustrated by Kiyotaka Haimura. The plot is set in a world where supernatural abilities exist. Kamijo is a student in Academy City, where people use science to develop supernatural abilities. The guy’s got a lot of heart – luckily for a young nun named Index. She’s on the run from a sorcery society that covets the astonishing 103,000 volumes of magical knowledge stored in her memory. When Index stumbles into Kamijo’s life, she find a faithful friend and protector, and while Kamijo’s easily the weakest kid in Academy City, he’s got something else going for him: the Imagine Breaker, an explainable power stored in his right hand that negates the powers of others.
