Last Order

Last Order (打ち止め) is the 20001st clone of Misaka Mikoto, that was produced as part of the Radio Noise project for the Level 6 Shift. She becomes an intergral part of the Toaru Majutsu no Index storyline after meeting with Accelerator who later dedicates himself to protecting her.

Appearance
Last Order is depicted as a 10-year old version of Mikoto with one unusual strand of hair that acts up in humorous moments in the manga. In her debut appearance, she's seen wearing a ragged piece of blanket as makeshift clothes. She is later given proper attire after being released from the hospital, wearing a blue spotted dress with a white coat and sandals.

Personality
Unlike her clone sisters, she is capable of actually showing emotions and has a close relationship with Misaka Imouto – a.k.a. Misaka 10032, Accelerator and her adult guardians, Yomikawa Aiho and Yoshikawa Kikyou. Like her older clone sisters, she speaks in third person, except she says "Misaka" twice. She has all of the memories of the Misaka clones and has observed Accelerator through this method during the experiment, posing a theory that Accelerator did not actually want to take part in the Level 6 Shift experiment and therefore doesn't blame him for his actions. She also has an apparent admiration of Touma due to him stopping the experiments and also protecting her during the events of volume 13.

Her appearance matches her childish nature, being playful and curious, such as taking Misaka 10032's goggles to play with as well as playing tag with her.

Background
She was the final clone produced for the Level 6 Shift project, though not as a part of the 20,000 clones selected to be killed by Accelerator so he could achieve Level 6. She functions as the command center of the Misaka clones and the administrator of the Misaka Network, making her their superior. According to Yoshikawa Kikyou, Last Order was created as a fail-safe mechanism in case the clones go out of control; by sending a set amount of brainwave signals to her, the researchers can control the Misaka Network from the outside.

Her name – Last Order – was derived from the scenario of Last Order commanding the clones to shutdown.

Sisters Arc

 * Main article: Sisters Arc

In the Toaru Kagaku no Railgun sidestory during the Sisters Arc, Last Order's silhouette is briefly seen inside an incubation tank. Here, the emotional program Nunotaba Shinobu created and tried to install unto the clones via the Misaka Network, has been installed solely in Last Order and the spread of the program into the network is being denied. Shinobu is caught off-guard by this, and is later caught by Kinuhata Saiai thus failing her mission to save the clones.

A few days after Touma defeats Accelerator and ends the experiment, Amai Ao director of the experiment, installs a virus into Last Order after becoming heavily indebted due to investing the now-failed project. Last Order's reaction to this is to break out of her incubation tank as a self-defense mechanism. She wanders the streets of Academy City for a while before meeting Accelerator.

Three Stories Arc

 * Main article: Three Stories Arc

Last Order's first physical appearance is during the Three Stories Arc where she asks Accelerator to help her find researchers of the experiment so she can be put back in her incubator. Last Order follows Accelerator to his wrecked apartment and spends the night with him in his room. After taking her out to a local family restaurant, Last order lectures Accelerator on his willingness to help a stranger and tells him he's not a bad guy at heart and is someone who never really wanted the experiment to go forth. As soon as he's about to storm out after hearing what she has to say, Last order collapses due to her weakened state. Accelerator leaves, unknowing that Amai Ao is about to abduct her.

Ao takes her outside the now-abandoned Radio Noise research facility and awaits the activation of the virus. Accelerator later arrives and renders Ao unconscious. Accelerator later discovers that the virus has started preparing to activate, and with no time left to spare, Accelerator chooses to save Last Order instead of killing her. Accelerator uses his vector powers to delete the virus inside of Last Order, and successfully manages to, though he gets shot by Ao in the head, as he was using all of his calculations on Last Order's treatment and not enough to spare for a deflection using his vectors. Even then, Accelerator protects Last Order from being shot by Ao using his powers, and tells Ao that even though the two of them are scum, they should not involve Last Order.

Yoshikawa Kikyou later arrives to put Last Order into an incubation tank after shooting Ao in the back. Last Order is then seen in the hospital that Heaven Canceler works in, where Misaka 10032 is looking after her.

Tree Diagram Remnant Arc

 * Main article: Tree Diagram Remnant Arc

Both Last Order and Accelerator are next seen bathing, and she makes fun of Accelerator's longer hair as well as him complaining about the bubbles getting into his eyes. Here, she indicates to Accelerator that she remembers everything that he did for her back in August, as she used the Misaka Network to back-up her memory, which irritates Accelerator. Last Order is next seen communicating with the clones regarding the Remnant of Tree Diagram and the possibility of the experiment restarting because of it, all the while hiding the fact that she is acquainted with Accelerator.

Last Order later asks Accelerator to help the sisters by destroying the Remnant that Musujime Awaki has stolen. In their battle, Accelerator states that even though he is not the strongest esper in the city anymore, he will become the strongest for Last Order; Accelerator then successfully manages to destroy the Remnant. The next day Accelerator is resting in his ward, but is bothered by Last Order who later cuts off the Misaka Network from him, disabling his ability to speak. Accelerator tries to comedically strangle Last Order because of this.

Daihasei Festival Arc
While she doesn't appear in the arc in person, in the anime she could be heard talking to someone, most likely Accelerator.

Fiama of the Right and World War III Arc
After the underground battle in Academy City, Last Order falls ill after Accelerator's encounter with Aiwass and the two of them set out for Russia to try and find a cure for her.

Abilities
Like the other sisters, she is considered an Electromaster (電撃使い). In addition to the abilities listed below, she can be turned into a core that is used to summon an 'Angel', when a certain code is forcibly put into her. This is demonstrated in volume 13, when FUZE=Kazakiri is summoned and also in volume 19 when Aiwass appears.


 * Electricity: Being a clone of Misaka Mikoto, she has the same abilities but at only 126/20000 of the original capability, making her a Level 3. She is capable of picking electric locks.

Being the administrator of the Misaka network, she can perfectly control what information travels flows through the network and she can conciously select who will receive it. She is known to have made 'a comical use' of this ability in the light novels : In certain instances and whenever she is arguing too strongly with the Accelerator, she will resort to removing his ability to speak in an attempt to force him out of the discussion; that usually brings an even bigger comical effect with having the Accelerator perform a certain type of pshycal punishment on her.
 * Radio Noise (欠陥電気): A form of telepathy between the sisters, it links her up to the "Misaka Network" as its administrator. She controls this system and can access their memories and experiences at will.

Quotes

 * (To Accelerator in Index manga chapter 29)"Misaka says Misaka was told that each Misaka's life has its own meaning. That there would be always be someone who would shed tears if a Misaka died. That's why Misaka won't die anymore, from now on none of us will die."
 * (To Accelerator in Index manga chapter 29, regarding Accelerator killing the clones)"Misaka says as Misaka is wondering, if that is the case, then why did you bother talking to the Misakas during the experiments? Many times... many times, even though there weren't many conversations. Misaka says as Misaka regrets that she couldn't notice your signs. If Misaka told you: 'I don't wan't to fight anymore', would you have stopped?"
 * (To Accelerator in Vol.22 when he is about to leave) "Please don't! Misaka Misaka wants to be with you forever"
