After not being involved in Kamijou Touma's battles for much of December, Index ended up being caught up along with him in the conflict resulting from the colliding plans of Aleister Crowley and Lola Stuart, which resulted in her acquiring her 103,001st grimoire and being freed from the control mechanism which the Archbishop had installed in her. Accompanying Touma and Aleister's group in their effort to defeat the Great Demon, Index returned to her home country, the United Kingdom, amidst the chaos of an invasion, which culminated in a decisive battle which saw the two long-time masterminds leave the stage.

With the one responsible for her initial situation gone and being saved in a similar manner to the first time after an unexpected occurrence, Index has chosen to return home with Touma to Academy City.

Christmas Eve Arc

Main article: 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.

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.

Index praying in the hospital's chapel, with Othinus on her shoulder

On Christmas Day, Index visited the hospital to see Touma, and prayed in the hospital's chapel, knowing the severity of his condition, caused by Anna Sprengel infecting him with St. Germain.

While Touma was facing Anna, Index and Othinus worked to save the many injured espers brought into the hospital who were in danger from the magic they had learnt from R&C Occultics and used without knowing the deadly side-effects, with a simple Christmas charm being ironically prominent among them.

Los Angeles Arc

Main article: Los Angeles Arc

This section requires expansion GT4

On December 26th, Index and Othinus accompanied Touma to Los Angeles along with Stiyl and Kanzaki, in the wake of the mass disappearance as the joint counterattack against R&C Occultics was initiated, with Index called upon to carry out her role as the Anglican grimoire library to identify the specifics of the magic behind the incident.

Post-Handcuffs Arc

Main article: Post-Handcuffs Arc

On the morning of December 29th, with the apartment's residents experiencing a lack of food due to Touma's lack of funds, Index was in a bad mood due to Alice Anotherbible's appearance (in Touma's blanket when he woke up), but was soon averting her eyes as Touma discovered she had eaten the last loaf of bread in the apartment in the middle of the night (with the empty bag scrunched up in the back of the cupboard and a collapsed Othinus having written the culprit's name). She remained at the apartment when Touma went out to the Tsukuyomi Residence for his supplementary lesson, along with Alice, and was absent from the events which followed.

New Year's Eve Arc

Main article: New Year's Eve Arc

This section requires expansion GT6

Index with Touma and the others in Shibuya.

On December 31st, Index accompanied Touma with Kumokawa Seria to Shibuya, as Touma sought a part-time job for survival money, with the group subsequently being involved in the events caused by Aradia and the Bologna Succubus over him.

New Year's Arc

Main article: New Year's Arc

On the morning of January 1st, Index returned to Academy City along with the rest of Touma's group and the captive Aradia. Briefly returning home, she accompanied Touma as he and the others visited School District 12 for a New Year's shrine visit. The next day, she went with the group to the Bridge Builders Cabal's newly-established consulate on Alice Anotherbible's invitation and stayed the night there.

On January 5th, after chomping on Touma's head and learning what he had gotten involved in while they were separated from him during the last two days under martial law, Index shared her mutual exasperation and frustration with Othinus at the whole mess involving Anna Sprengel, the Transcendents and "CRC". That evening, Index and Othinus were involved in the initial clash with "CRC" at the first defensive line in School District 12, but when the initial group was separated, the two intentionally left the battlefield so they could observe from afar and try to figure out their enemy's weaknesses. Having witnessed "CRC" being set flying away during the final battle at Heaven Canceller's Hospital, the two headed for the fallen enemy to finish him off, knowing that Touma wouldn't be able to win a second time. However, they instead witnessed a resurrected but headless Alice Anotherbible expose and kill the CRC imposter, Johann Valentin Andreae.

Hell Tour Arc

Main article: Hell Tour Arc

During the journey through hell in order to resurrect Kamijou Touma on January 7th, Anna Kingsford showed Touma a glimpse of living friends and acquaintances (Index first among them), displaying their reactions in order to motivate his drive to return to life and overcome the false resignation hell's influence was imposing on him.
