T1, E2: The magician introduces himself as Stiyl Magnus and explains that his partner Kaori Kanzaki unintentionally hurt Index as her magical garb was supposed to stop the blow. His mission was actually to protect Index, who possesses photographic memory of the 103,000 grimoires implanted in her mind called the Index Librorum Prohibitorum. Angered by Stiyl's ill treatment of Index, Tōma attacks him, to which Stiyl responds by using fire magic and is surprised when Tōma nullifies the spell. To stop Tōma, Stiyl summons a fire creature known as Innocentius. When Tōma finds himself unable to negate the creature, Index activates John's Pen, her self-protection system personality, to reveal that Innocentius' power comes from runes placed around the building. Tōma defeats Stiyl and Innocentius by setting off sprinklers to wash away the runes. However, because of Index's wounds and Tōma's inability to use magic, he brings Index to the only non-esper he knows, that being his teacher Komoe Tsukuyomi.
