An Amakusa Catholic girl. She seems to have romantic feelings towards Tōma bordering on actual love but due to her shyness, she was not able to act on them and convey them to him. She has accompanied Tōma and friends on more than one occasion, going to, Italy, France, and then England with him. In the events of the 16th novel she becomes his caretaker. When Acqua first attacks, she fails to protect Touma, trying unsuccessfully to heal him with magic several times due to his Imagine Breaker. After Touma is sent to the hospital she is seen despairing because of her failure. She is rebuked by Tatemiya Saiji, who tells her to stop feeling sad and look to the future, when Acqua will come and attack again, and that she should focus on proving to Touma that it was worth his time protecting her from Acqua. During the Amakusa Catholics&#039; rematch against Aqua after Tōma was nearly killed, she displayed a sudden change of personality, becoming full of tranquil fury that even the way she spoke changed. She performed a &quot;Saint Destroyer&quot; in that battle, harming Acqua causing him to lose the &quot;Divine Mother&#039;s Mercy&quot;. Her weapon is a Friulian Spear which by adding layers of reinforcement, it turns the spear to a symbol of a &#039;Thousand Years Tree&#039;, which symbolizes the growth of plants and makes certain magic spells to be more potent over time and she also can perform Nanasen (七閃?, &quot;Seven Flash&quot;) by manipulating her spear and steel wires just like Kanzaki Kaori.

Index is still a fugitive, and many powerful magical organizations and individuals want to take her to use the books in her memory, eliminating her in the process. War between those organizations is also starting to emerge. Index can only rely on her friend Touma, who has always protected her, along with Misaka and other friends from the Academy.

The story is set in a world where supernatural powers exist through science, and magic exists through religion. 
In the story, Touma Kamijou is an ordinary high school boy with terrible academic scores and a power called Imagine Breaker. Imagine Breaker can defeat any other power, but it also undermines Kamijou's own good luck. His Imagine Breaker's immense strength is literally immeasurable, so hapless Kamijou is listed at the supernatural level of 0. He happens to meet a girl in white hanging off his window balcony. The girl says she is being chased by sorcerers, and Kamijou learns that the girl is a Church of England nun whose memories have been forcibly replaced by Index-Librorum-Prohibitorum &mdash; the 103,000 forbidden texts of the Church.
