Chronology

Shinyaku Toaru Majutsu no Index

Agitate Halation Arc

Main article: Agitate Halation Arc

During the riots in Academy City's Learning Core involving 7,500 "heroes", a group of people assume that a boy claiming to be Aihana Etsu is the Number Six since he defeated them with only his fists and without any apparent ability. Shokuhou Misaki, noticing him, claims that he is pretending to be the Number Six Level 5, and therefore has no connection to her, indicating that she probably knows the real Aihana Etsu.

In the conclusion of the arc, Kihara Noukan states that "the Level 5s gathered in one place", hinting either that the real Aihana Etsu actually was present in Learning Core, that Noukan was simply only referring to the other Level 5s, or that Noukan was fooled by the impostor's acting.

Magic God Othinus Arc

Main article: Magic God Othinus Arc

Aihana officially debuts in person in this arc, though their features are kept nondescript and they are referred to as the Number Six rather than by name. When Academy City sends an email to the seven Level 5s "requesting the death of Magic God Othinus and Kamijou Touma who is traveling with her", Aihana silently toys with the phone.

St. Germain Arc

Main article: St. Germain Arc

Following the events at the Dianoid, during which Kanou Shinka made use of Aihana's name, the real Aihana speaks with Yokosuka, who has been assisting Aihana (hoping that he could learn how to beat Sogiita Gunha) with their plans of helping people solve their problems by allowing them to use Aihana's name as the sixth ranked Level 5 on Aihana's behalf, Yokosuka having passed the name on to another.

Christmas Day Arc

Aihana Etsu approaches Kamijou Touma

On Christmas Day, Aihana Etsu approached the heavily injured and dying Kamijou Touma, who was attempting to leave hospital to stop Anna Sprengel, despite his condition. Though he had negative view of Touma and had avoided making contact before then, Aihana apparently deemed supporting Touma with his power the best choice for fighting R&C Occultics. He attempted to have Touma take on his name and grant him power like he usually did with others, but Touma rejected his offer and called out his attitude. Both unwilling to budge, Aihana stood in Touma's way and was quickly knocked out.

Trivia

• In Toaru Majutsu no Index Volume 3, Kamijou Touma stumbles upon the esper names of the seven Level 5s in documents related to the Level 6 Shift project, but he skips past those names.
• Some fans speculate that the Number Six is Aogami Pierce (thus making "Aihana Etsu" his real name), since pre-memory loss Touma considered him and Misaka Mikoto "tough people who he would not have to worry about getting involved" in the trouble revolving around Index.
• After the release of Shinyaku Majutsu no Index Volume 7, there was confusion over whether the name "Aihana Etsu" was the Number Six's real name or just the impostor's name. In Shinyaku Majutsu no Index Volume 12, Yokosuka confirmed it as the former.

Quotes

• "Now, picture the you that you wish to be. Picture your ideal self.”[...]“You can be that version of yourself. Now, I will lend you Aihana Etsu."
