Toaru Majutsu no Index Episode 05

"Limit" is the fifth episode of the first season of the Toaru Majutsu no Index anime series. It was first broadcast on November 2, 2008, and was directed by Kawamo Shinya and written by Akahoshi Masanao.

103,000 grimoires have been contained inside of Index, and as a result she can only use 15% of her brain. This is her power of recollection, however, because of this each one year cycles requires for her memories to be erased lest she dies. That fact has been beaten into Touma's head, the fact that she may never even know that she had contact with him in the first place. The time limit is 12 midnight, and once pass it, Index will die. As such, Touma is allowed to say goodbye to Index. However, as Index's nightmare begins and her body experiences great pain and severe fever, Touma tries to find some way for her to live without erasing her memories. All efforts are in vain however, as Kanzaki and Stiyl appear before him. Is there a sure fire way for Touma to save Index?

Synopsis
Komoe leaves Touma and Index alone for the entire evening. Index lies sleeping on the futon; Touma recalls earlier on how both Stiyl and Kanzaki willingly left them as they would return later, and expecting Touma to not flee with Index, and having Index collapsing immediately after. Touma later gets a call from Kanzaki, she tells him that the limit is at midnight and they are preparing their schedule to finish in time, she tells him that the reason why she is telling him this is that she wants Touma to say his farewells. Touma asks if magic can't really solve anything, Kanzaki tells him that the church fears Index's rebellion as the holder of the 103,000 grimoires as such the church may have done some precautions as so Index would be unable to learn a spell to cure her. Magic can't save Index. However, Touma asks Kanzaki if "they" are able to do something, the science side.

Touma says that their side may find the way to cure Index; however, Kanzaki says that the magic side do not trust his betting on the side, as he has no evidence to support that it might actually help Index. Touma then resolves that he will find a way for himself and that he will steal the heroic moments from them, intrigued by this, Kanzaki tells Touma to show them how he will struggle through it until the end.

Touma starts researching about memory loss, and later realizes that he can ask Komoe to introduce him to neurological or mental research institutes. He tries to contact Komoe, but she is busy enjoying her bath and cannot get to her phone. Touma then opts to call random places to help him, however most if not all of them have already closed down for the night, he finds one that is still operating, but is turned down because they believed Touma was fooling with them. Touma realizes that is already midnight and Index has begun breathing heavily.

Kanzaki and Stiyl arrives to erase Index of her memories, however, Touma is still adamant that Academy City but is chatised by Stiyl. He later shows Touma a magical cross that is necessary for memory erasure, and challenges Touma to dispel the magic within it, if he is capable of saving her without erasing her memories; Touma is however unable to do it, and Stiyl leaves to continue the ceremony in erasing her memories. Touma in despair asks them to allow him to say his goodbyes to her; though reluctant at first - and with a little prodding by Kanzaki – Stiyl allows Touma to have some time alone with Index.

They leave, and Touma is left alone with Index who awakens. Index notices the symbol drawn by Stiyl on the wall for the ceremony, making Index worry; however, Touma calms her down and apologizes to her, and says that he will become stronger and never lose again to those who have made her this way. He asks her to wait for him, and that he will save her all the way next time. Index smiles and says that she will wait for him, before falling asleep again. Touma continue to reprimand himself for failing to save her, after she falls asleep, however he becomes suspicious of the information regarding Index's brain.

Because of the suspicion behind the information regarding Index's brain, he calls Komoe again – who finished her bath – and asks her about perfect memorization and the information that he was told. Komoe tells Touma that the human brain will not deteriorate if it can perfectly memorize anything, and can in fact store 140 years worth of memory. She goes on to say that the brain does not store memories in a single place, but rather sorts them out depending on what type of information it is; she concludes that it is impossible in neurology for the brain to break down, no matter how much knowledge is in it. With her lecture finished, Touma ends the call and focus her attention on Index.

Now knowing that Index shouldn't even suffer with the knowledge inside her mind, he concludes that the church lied to Stiyl and Kanzaki, and tampered with Index's body as so she would deteriorate if her memories were not erased every year, as such Index who possesses the 103,000 grimoires would be incapable of betraying them. Determined to save Index, Touma removes the bandages from his hand and touches Index's forehead hoping to dispel something, though there was no reaction. However, he notices a strange symbol embedded inside Index's mouth; Touma inserts his middle finger into Index's mouth, touching the symbol and dispels it.

Almost immediately, Touma is knocked back by the force and acquire injuries on his finger. Index rises and charges towards him, causing an explosion which alerts Kanzaki and Stiyl. A machine-like Index's speaks before them in monotonic fashion; she constructs a weapon from one of the 103,000 grimoires she has in her possession, a weapon that is the most effective against Touma, St. George's Sanctuary.
