"Index of Necessarius" ( 必要悪の教会の禁書目録, "Nesesariusu no Indekkusu") "Shadow Under the Moon" ( 月下閃影, "Gekka Sen'ei") The next day, a recovering Index introduces Tōma to her religion. He later brings Index to his homeroom teacher named Komoe Tsukuyomi for assistance in healing her. Tōma manages to defeat Stiyl after he destroyed the runes surrounding the dormitory's floor, which kept the creature alive. Stiyl finds his magic attacks useless against Tōma's Imagine Breaker but he still summons a fiery creature called "Innocentius". After he attended his supplementary lessons and encountered Mikoto again, Tōma finds a wounded Index in front of his room when a magician named Stiyl Magnus showed up to retrieve her. Afterwards, Index leaves as she is being pursued by magicians seeking the 103,000 grimoires in her head. Index and Tōma then engage in a debate about the existence of magic and his right hand's power called "Imagine Breaker", which could negate any supernatural abilities. She introduces herself as Index from the Church of England. The following morning, Tōma finds a hungry nun hanging on his dormitory's balcony. On the night of July 19, Toma Kamijo meets Academy City's #3 Level 5 Mikoto Misaka at the bridge after he saved her from delinquents inside a restaurant.
