Plot
Toaru Majutsu no Index is set in Academy City, a technologically advanced city located at western Tokyo which studies scientifically advanced superhuman students with powers, but is also set in a world where magic is real.

Kamijou Touma is a high school student in Academy City, with a power called the Imagine Breaker that can negate all magic, psychic, and divine powers, but also his own luck. One day he finds a young girl named Index hanging on the balcony railing of his dormitory room. She turns out to be a nun from the Anglican Church, and her mind has been implanted with the Index Librorum Prohibitorum — 103,000 magical texts that contain a wealth of information about magic. His encounter with her leads him to meet others from the secret world of science and magic and an adventure with his friends where science and magic collide. Touma's unusual power places him at the center of conflicts between magicians and science-based espers in Academy City. As Touma tries to help and protect his friends, he learns the people he knows are not as they appear and begins to attract the attention of magicians and espers alike as they try to unravel the secrets of Academy City and Index.

 * A technologically-advanced city located within western Tokyo, composed of educational and research facilities which focus on the advancement of science. Its population is mostly composed of students.


 * Espers (能力者)
 * People who possess psychic abilities like telekinesis and clairvoyance. A vast majority of espers are ordinary people, especially students whose powers are acquired through participating in the Power Curriculum Program in Academy City, while a rare kind of esper, called Gemstones, are espers whose abilities are present since birth.


 * Magicians (魔術師)
 * Magicians are ordinary people who desire powers like their psychic counterparts. Using a variety of methods, they use magic spells in various tasks.

 * Index Librorum Prohibitorum (禁書目録)
 * A collection of 103,000 magical books called Grimoires which is implanted on Index's brain. These powerful books contain vasts amounts of knowledge, and is considered to be poisonous to any person, even to experienced magicians.

Light Novels
The light novels have been published by ASCII Media Works under their Dengeki Bunko label since April 10, 2004. As of March 2011, there are twenty-three main novel volumes and two short story collections. After Volume 22, Kamachi announced a break of several months, in which he released the New Testament (新約　とある魔術のインデックス, Shinyaku Toaru Majutsu no Index) series, which continues the story of Toaru Majutsu no Index.

The main light novels usually consist of around four or so chapters, with a prologue and epilogue depending on whether the novel is part of a multi-volume arc, and additional small sections depending on circumstances. The individual chapters are divided up into several parts. Aside from these normal parts, chapters may also include a section at the end titled "Between the lines" (行間), which elaborates on background details separately from the main narrative. A notable exception to this pattern for the main novels is Shinyaku Toaru Majutsu no Index Light Novel Volume 04. The side-stories may also differ from this pattern. Chapter names usually consist of a part written in Japanese, followed by a part written in English (e.g. 彼らのそれぞれの戦場　The_Way_of_Light_and_Darkness., Their Respective Battlefields — The_Way_of_Light_and_Darkness. ). Chapters are numbered depending on whether the novel is separate or part of a multi-volume arc (e.g. if the previous volume in the arc ended on Chapter 4, the next volume will begin with Chapter 5).

Drama CD
A drama CD was released as a mail-in order of Dengeki hp Volume 48 and was released later in November 2007.
