Toaru Majutsu no Index

Toaru Majutsu no Index is set in Academy City; a technologically advanced academic city located in western Tokyo which studies scientifically enhanced superhuman students known as espers who develop powers. However, within this world of scientifically developed superpowers exists an underground world of magic and occult connected to the religious institutions of the world. Kamijou Touma, an unlucky boy who happens to be one of the many students within Academy City, possesses a mysterious power in his right hand known as the 'Imagine Breaker'; an ability which allows him to negate all forms of supernatural powers, whether they are magical or psychic. One day, he finds a young girl hanging on his balcony railing named Index. She is a nun from Necessarius, a secret magic branch of the Anglican Church, and her mind has been implanted with the Index Librorum Prohibitorum: 103,000 original grimoires that the Church has removed from circulation. Their encounter leads him to meet others from the secretive worlds of science and magic. Kamijou Touma's unusual power places him at the center of conflicts related to both science-based espers in Academy City and magicians. As Kamijou Touma tries to help and protect his friends, he learns that 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.
