Toma learns that Stiyl and Kaori will come at exactly midnight to perform the spell to erase Index's memory. Despite Toma's attempts to find another way to save Index, midnight arrives and he is helpless as Stiyl and Kaori arrive to prepare the spell. The duo give him time to say good-bye to Index; in this time, Toma becomes suspicious of Kaori's statement that Index's memory only has 15% for daily life in a year. Calling up Komoe, he learns that humans can never suffer or die from being overloaded with information and realizes that the Church regularly erased Index's memory to ensure her loyalty to them and lied to Stiyl and Kaori. Determined to save Index, Toma tries to dispel a magical rune in her throat, only to activate Index's Johann's Pen mode. Unable to analyze and devise a means of countering Toma's ability, Johann's Pen activates "St. George's Sanctuary", a spell it has determined as the most effective way of eliminating Toma.
