The side-story, A Certain Scientific Railgun, focuses on Mikoto Misaka, an electromaster who is the third most powerful of the seven Level 5 espers in Academy City. As TЕЌma 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. TЕЌma's unusual power places him at the center of conflicts relating magicians and science-based espers in Academy City. 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. She is a nun from Necessarius, a secret magic branch of the Church of England, and her mind has been implanted with the Index Librorum Prohibitorum-103,000 forbidden magical books the Church has removed from circulation. While the first season of that serves mostly as a prequel, events from later in the source material occur at the same time as its parent story.

After the first season of the anime, an anime adaptation of its spin-off manga, A Certain Scientific Railgun, began. One day he finds a young girl hanging on his balcony railing named Index.
