A Certain Magical Index

Season 1

Episode 2: The Witch Hunting King (Innocentius)

The magician introduces himself as Stiyl Magnus and explains that his partner Kaori unintentionally hurt Index as her magical garb was supposed to stop the blow. His mission was actually to 'protect' Index (actually the Index-Librorum-Prohibitorum, the 103,000 books implanted in her mind) as she possesses photographic memory. Angered by Stiyl's ill treatment of Index, Toma attacks him, to which Stiyl responds by using fire magic and is surprised when Toma nullifies the spell. To stop Toma, Stiyl summons a fire creature known as Innocentius; when Toma finds himself unable to negate the creature, Index's Johann's Pen mode reveals it is because Innocentius' power comes from runes placed around the building. Toma defeats Stiyl and Innocentius by setting off sprinklers to wash away the runes and rescues Index. However, because of Index's wounds and Toma's inability to use magic (due to him being an esper), he brings Index to the only non-esper he knows: his teacher, Komoe Tsukuyomi.
