Following the fake date incident with Mikoto, Toma still hasn't finished his summer homework and Index isn't helping much. While Toma takes Index to a restaurant for a change of location, they are attacked by magician named oma Yamisaka who kidnaps Index and runs off. As Toma tries to find her, running into Mikoto along the way, oma prepares a ceremony that will allow him to access the grimoires inside Index's head in order to find a cure for a curse inflicted on a woman he has fallen in love with. As the ceremony begins, oma's body and mind is put through excruciating pain trying to access the grimoires. Thanks to Index using her new cellphone, Toma is able to find her and stop the ceremony. Toma gets oma to snap out his depression and offers to cure the woman's curse using his Imagine Breaker. Meanwhile, Kaori is seen fighting the Knights of England in Japan.
