To Aru Majutsu no Index (とある魔術の禁書目録, To Aru Majutsu no Indekkusu?, lit. A Certain Magical Index) is a Japanese light novel series written by Kazuma Kamachi and illustrated by Kiyotaka Haimura; the series is published by ASCII Media Works under their Dengeki Bunko imprint. Set in a city of scientifically advanced superhuman students, but in a world where magic is also real. Toma Kamijo's right hand, the Imagine Breaker, will negate all magic, psychic, or divine powers, as well as his own luck. One day he finds a young girl hanging on his balcony railing. She turns out to be a nun from the Church of England, and her mind has been implanted with the Index Librorum Prohibitorum—all the magical texts the Church has removed from circulation. The series was made into an anime and premiered on October 4, 2008.
