Misaka Mikoto/Chronology (Souyaku Toaru Majutsu no Index)

Christmas Eve Arc
Shortly after midnight on the morning of December 24th, Mikoto managed to escape from Tokiwadai's strict Christmas oversight by working together with Shokuhou Misaki and then abandoning her before she could be betrayed. She then encountered Kamijou Touma as he was escaping from some delinquents, carrying a naked girl who had filmed the group's attempt to rob an ATM.

Later in the morning, she ran into him again while fleeing from a group of Tokiwadai teachers and students. After hiding from her pursuers, she accompanied Touma and Index as they spent their Christmas Eve in the city (with Touma's remedial lessons having been scuppered earlier), ending up having a game of darts in a bar, with penalties.

Following the game's conclusion, the group encountered Misaka 10032 and Last Order, shortly before getting caught up in an attempt to kidnap the latter by individuals seeking to thwart Accelerator's Operation Handcuffs, a plan to eliminate the Dark Side of Academy City. After Touma defeated Maidono Hoshimi and the kidnapping was thwarted, the group learnt of Accelerator's endeavour and decided to face the mastermind behind the resistance, Director Neoka Norito.

Arriving in the evening as Anti-Skill was about to move in, the group witnessed an explosion at Neoka's home, set off by Neoka himself as part of a ploy to fabricate injuries and blame Anti-Skill to impede their investigation and buy time to destroy evidence. With Mikoto's ability, they scaled the building and got to the roof before Neoka could have himself injured and escape via air ambulance, forcing the director to try to eliminate them himself. While Neoka initially held the upper hand due to unexpected use of magic acquired from R&C Occultics, Touma and Index soon recognized what he was doing, and with Othinus's help, Touma was able to turn the tables and managed to defeat Neoka in a final physical clash before collapsing himself due to his accumulated injuries.

After the group left the scene and returned to street level, Touma was suddenly approached by Anna Sprengel, the one behind R&C Occultics, who swiftly moved in before the others' eyes and kissed him, exposing him to the contents of a black pill in her mouth.
