Toaru Majutsu no Index (anime)

Toaru Majutsu no Index (とある魔術の禁書目録（インデックス）), translated as A Certain Magical Index, is the anime series adaptation of the light novel of the same name produced by J.C. Staff. The anime series was directed by Nishikiori Hiroshi and written by Akahoshi Masanao for the first two seasons and Yoshino Hiroyuki for the third, with music by Iuchi Maiko, art and sound direction by Ebina Yasunori, and character designs by Tanaka Yuichi based on the original designs by Haimura Kiyotaka.

The series is currently composed of two 24-episode seasons and one 26-episodes season, which follows the story in the light novels of Kamijou Touma and his adventures following an encounter with Index, a nun that carries 103,000 grimoires in her head.

Plot
The anime series closely follows the story of Kamijou Touma, a high school boy studying in Academy City, a city in Japan known as a hub for many educational and scientific institutions, but also for its Power Curriculum Program which aims to help students develop esper abilities. Touma is considered a weakling by many because he is considered a Level 0. However, he manifests an unusual ability to dispel supernatural phenomena using his right hand, which he calls Imagine Breaker.

In the first season, Touma meets Index, an English nun who is in pursuit by her "guardians" who make sure that the 103,000 magical books in her head do not fall into the wrong hands. Index eventually becomes Touma's companion at home, while Touma faces multiple agents from both within Academy City and magicians who sneak into the city due to various reasons, most notably to directly attack the city as part of the ongoing power struggle between magic and science. The second season involves the Roman Catholic Church, a major faction in the magic side, targeting Touma for posing a threat against the organization. The third season picks up from where the previous season left off, as Touma comes into conflict with God's Right Seat, a secret faction of the Roman Catholic Church, which only promises to bring the magic and science sides closer to a full-blown war. The first season covers Volumes 1 to 6 of the light novel, while the second season covers Volumes 7 to 13 and the first side story volume, and the third season covers Volume 14 to 22, the final novel of the original series.
