A Certain Magical Index is een Japanse animeserie te zien bij Netflix. De serie ging in première op 4 oktober 2008.
Set in Academy City, a city of scientifically advanced superhuman students, located to the west of Tokyo, in a world where magic is also real. Kamijou Touma's right hand, the Imagine Breaker, can negate all magic, psychic, or divine powers, but not his own bad luck. One day he finds a young girl, Index, hanging on his balcony railing. She turns out to be a nun from the Church of England, and her mind has been implanted with the Index Librorum Prohibitorum — all the magical texts the Church has removed from circulation. His encounter leads him to meet others from the secret world of science and magic and right into an adventure where science and magic collide.
Imaginary Number School District - Five-Element Agency
Tōma pursues Hyōka but encounters Sherry instead and is forced to fight her. He learns that Ellis was once a friend of Sherry who suffered painful consequences from an attempt by Necessarius and Academy City to reconcile magic and science; to prevent this tragedy from occurring again, Sherry intends to divide them forever through conflict. Outraged that Sherry does not believe that people who are different like Index and Hyōka could be friends, Tōma successfully defeats Sherry. However, doing so results in Golem Ellis above ground losing control, and Index is cornered until Hyōka suddenly appears and destroys the Golem each time it reforms. After Tōma arrives to deliver the finishing blow, Index and Hyōka reconcile just as Hyōka fades away to the Imaginary Number Sector. Meanwhile, Tsuchimikado confronts Aleister Crowley on why he is interested in the Imaginary Numbers Sector. As each of the characters settle back into their daily lives, Stiyl meets with the Archbishop of Necessarius, Laura Stuart, who decides that Necessarius will need Index and Tōma's help for an upcoming problem meanwhile Kaori Kanzaki is missing in Japan after the events of the Angel Fall.
