S1, E6: After Tōma convinces Stiyl and Kaori that they were tricked by Necessarius about Index's condition and that destroying the magic responsible for Index's pain will allow her to live a normal life, Tōma is able to disable her John's Pen mode with help from Stiyl and Kaori. However, St. George's Sanctuary remains in effect and Tōma is rendered unconscious when a feather from the spell touches his head. At the hospital, Index discovers that Necessarius will leave her alone for now since Stiyl and Kaori are now questioning why the Church lied about her condition and that Tōma's memories have been erased since the spell destroyed his brain cells. At first, Tōma says that he is unable to recognize Index when she goes to see him, but brushes it off as a joke and explains that he canceled the spell with his right hand's ability, now called Imagine Breaker, before she leaves. What Index does not know is that Tōma really was unable to remember anything but did not want to burden Index with his condition, though feeling that his memories still remain in his heart. Two weeks later, Stiyl meets Aleister Crowley, the ruler of Academy City, and to keep the status quo of non-interference between science and magic, Aleister lends Tōma to Stiyl for an assignment to rescue "Deep Blood", someone capable of killing vampires, from a magician in Academy City.
