Christmas Eve Arc
On the morning of December 24th, after Kamijou Touma's remote remedial lessons were scuppered by a technical failure and not knowing Tsukuyomi Komoe's location, Index accompanied Touma to spend their Christmas Eve in the city, being joined by Misaka Mikoto, who ran into them while fleeing from a group of Tokiwadai teachers and students. After wondering how to spend the time, they ended 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.
