Plot
Toaru Majutsu no Index is set in Academy City, a technologically advanced Academic 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, 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 hanging on his balcony railing named Index. She turns out to be a nun from the Church of England, and her mind has been implanted with the Index Librorum Prohibitorum — 103,000 magical texts of the Church. 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.

Second Season
After his involvement with various magical affairs involving the Anglican Church-based organization Necessarius, Kamijou Touma finds himself in a bigger mess than before. Due to unexpected circumstances, Touma becomes a changing force in the conflict between magic and science when he thwarts many plans organized by the Roman Catholic Church, culminating with the direct actions of the most powerful magical group based on the Roman Catholic Church, God's Right Seat.

Espers (能力者) Also known as psychics, they are people who possess supernatural abilities or psychic abilities. A vast majority of espers are ordinary people whose powers are acquired through participating in the Power Development Curriculum 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. Although magic is designed such that ordinary people can learn and use it, its high incompatibility with psychic powers causes espers to suffer bodily injury (if not instant death) when they use magic spells.

Index Librorum Prohibitorum (禁書目録) A collection of 103,000 magical books called Grimoires which is implanted on Index's brain.
