A Certain Magical Index

Kamijo meets Index, who is on the run from a magic society that wants the library of forbidden knowledge stored in her memory. Later, Kamijo is shocked to find Index at his house – bleeding and accompanied by a strange man.

Kamijo tangles with Stiyl, upset with the magician’s rough behavior toward Index. When quick thinking allows Kamijo and Index to escape, they head to the one person that might be able to help them.

While Komoe helps Index in healing her wounds using magic, Toma meets Stiyl's partner, Kaori Kanzaki and learns from her why they are hunting Index and the organization, Necessarius, The Church of Necessary Evil.

Touma learns the truth about Index's perfect memorization and her loss of memories.

Touma tries desperately to save Index's memories before it is too late.

Following the events of last episode and the activation of Index's defense mechanism Touma struggles to hide his amnesia from Index.

Stiyl and Touma join forces to investigate the mysterious Misawa Cram School.

Touma encounters Ars Magna the leader of Misawa Cram School and a man with his own connection to Index.

Touma faces off against Accelerator for the sake of Misaka and her 'sisters'.

Touma and Index head to the beach to avoid the fallout from Touma's fight with Accelerator. They also plan to meet Touma's Family but when they arrive they aren't quite what Touma was expecting.

After figuring out the truth of Misha’s real identity, Kanzaki sends Kamijo and Toya to destroy the ritual spot. When Tsuchimikado suggests that Toya must die for the spell to end, a violent – and seemingly fatal – encounter ensues.

In order to shake off the unwanted attention she’s getting from Unabara, Misaka asks Kamijo to pretend to be her boyfriend. Things get complicated when the faux-couple discovers that Unabara is hiding a magical secret.

Accelerator meets the last of Misaka’s clones – Last Order – who explains the special role she played in the Sister experiment. Later, Accelerator learns what steps he’ll have to take to keep Last Order safe.

After Accelerator frees Last Order of the virus infecting her brain, he’s attacked by gun-wielding Amai. Just as all appears lost for Accelerator, Yoshikawa arrives to help – but Amai isn’t going down without a fight.
