Railgun S Episode 5
He is the second protagonist of the Science Side in the Toaru Majutsu no Index series. First appearing chronologically in Toaru Majutsu no Index as an antagonist, he later becomes the primary male protagonist of the Science Side after being defeated by Kamijou Touma. He is a member of GROUP since Volume 13 of the light novels, when he was forced to join after hearing how it was the best way for him to protect Last Order. As the most powerful esper of Academy City, his existence and powers are tied to the plans of Aleister Crowley, the founder of Academy City, alongside Kamijou Touma.
Accelerator appears as a skinny teenager and has pale skin, moppy white hair and red eyes. This is caused by his ability, as it blocks ultraviolet rays, thereby preventing his body from producing melanin. His ability also has an effect on his hormones, as he stated in both the novel and manga series that it was because of his power he has "...this genderless body," although there is definite evidence stated throughout the series that he is a boy. In the novel/manga/anime, when Last Order asked him "Then are you male or female?" he gave the equivocal answer, "Can't you tell?" While in the novel he is shown to have a slim, androgynous body, a bathing scene depicted him as bare-chested and obviously male.
He also seems to have an affinity for black and white-themed clothing. He changes his initial clothing from a black shirt with white striped patterns to a white shirt with V patterns. He starts wearing a choker-style electrode to aid him with mobility, computation and communication, although he states that it makes up for less than half of his former calculation abilities, and uses a cane.
When he is enraged or excited such as when fighting a strong or amusing opponent e.g Kamijou Touma during their first encounter, he breaks into a wide grin and laughs, giving him a maniacal and sadistic appearance.
Due to the potential of his ability, Accelerator has been targeted by assassins and researchers throughout his life. As a result, he believes only in power and trusts no one. While fighting, he invokes fear and has a sadistic tone. He willingly joins the SISTER experiment to gain a reputation as the most powerful and feared psychic so that no one would dare be foolish enough to challenge him and won't hesitate to kill any who get in his way. The Sisters' memories of his behavior during the experiment may suggest that he is, in a way, a pacifist; because his power won't disappear, the only way he sees an end to the fighting is to be so strong and sadistic that no one would dare to raise a finger against him. He even seems to attempt to frighten the Sisters out of fighting or otherwise encourage them to refuse their battles.
After meeting Last Order, he strives to protect her (although he states he does not like her company, he tolerates her). He saved her from Amai Ao's plot and from being pursued by the Hound Dogs. He treats Index in a similar fashion, such as when he buys her lunch while searching for Last Order and by protecting her from the Hound Dogs. By Volume 19, he has mellowed out to the point that he actually lectures a child in order to prevent him from getting himself killed after a hostage situation.
His attitude towards Touma was hinted at throughout the novels after Volume 5, when it is shown that he both idolizes and is slightly jealous of Touma's heroic personality, and is outright shown when he and Touma finally come to blows in Volume 20. By comparison according to Heaven Canceler, Touma and Accelerator are very similar, but their methods are like opposite sides of a coin; Touma is able to protect his loved ones without killing and is able to stand by their side, while Accelerator protects his loved ones through violent methods and even admits that he is unable to stand by Last Order and Yomikawa's side. Deep down, he is someone that aches for the light, as shown when Yomikawa was able to walk up to him and slowly take a gun from his hands before he tried to finish off Kakine after their fight, and later when he refused to hurt a Misaka WORST clone and tried to heal her wounds after she tried to kill herself.
Aiwass has also commented on the differences between Touma and Accelerator – stating how Accelerator craves for the wholesomeness of being a 'hero' like Touma, even to the point that he declared himself evil because he believes he cannot reach that level. He is someone that tries hard to redeem himself.
Accelerator was shown to often underestimate his enemies earlier in the series, which led to his loss against Touma. However, after nearly being killed by Kihara Amata and fighting Komaba Ritoku, he no longer underestimates his enemies. This fact is noted by one of the terrorists in Hula Hoop in Volume 19 as possibly being the most terrifying thing about him: he always uses exactly how much force he needs to in order to defeat his enemy: no more and no less. If he ever underestimated his enemies, it would have given them an opening they could have exploited, but since he didn't, he simply wiped them out.
In Vol22 After-word the author states that what Accelerator wants most is not a lover but a family, and states Last Order is like his child he has to take care of. Also in Vol22, Misaka Worst said half-jokingly she wants the same fatherly treatment he gives to the other Misaka clones.
BackgroundEditMuch of his past is unknown, but Accelerator mentions that he once had a "normal name" which has yet to be revealed, and most likely never will, as Accelerator himself forgot it. The novels state that his last name consists of two kanji and his first name three.
Ever since taking the Power Curriculum Program, and realizing his powers, Accelerator was sent to a "special class", most likely, the Special Ability Institute, and spent much of his childhood there until age nine, before being moved into another special class. Both of these had him as the only student. It can be presumed that this occurred before the incident involving the military.
Accelerator as a child couldn't fit in with the other children due to his powers, harming those that tried to get close to him. Around age ten, a particular incident with children escalated with Academy City being deployed against him, and he later "gave up", and was sent to a special class. This has made him something of a loner and distrustful towards other people. After some time, Accelerator was discovered by Kihara Amata, who trained him in how to control his powers and influenced him enough for Accelerator to adopt his personality. It can be assumed that the Dark May Project started after Accelerator acquired the cool personality he now has from Amata.
Accelerator's ability made him the subject of an experiment attempting to create the first Level 6 psychic; according to the city's best supercomputer, Tree Diagram, this feat could only be achieved by killing Misaka Mikoto, the 'Railgun', 128 times. However, because it was impossible to create 128 of these 'railguns', due to the 'Level 5 Mass Production Plan' only being capable of producing a sub-standard clone of Mikoto at a power of Level 2-3, a substitute plan was arranged where Accelerator would have to kill 20,000 Misaka clones in a variety of methods. He willingly joins the experiment to gain a reputation as the most powerful and feared psychic so that no one would be foolish enough to challenge him ever again. By the beginning of the Sisters Arc (index), Accelerator has already killed the first 10030 Misaka Clones and during the course of the arc, kills clone 10031 before the experiment is ultimately stopped.
Later it is revealed he originally wanted this reputation simply so that no one would ever get hurt trying to attack him, resulting in their own destruction, though as he went deeper into Academy City's dark side his goals slowly became more and more twisted.
Toaru Majutsu no IndexEdit
- Main article:Sisters Arc
In one of the battles, he kills a clone in a vicinity near Kamijou Touma. This event causes Touma to intervene in the experiment. Touma uses the logic that if the weakest Level 0 (Touma) can defeat the strongest Level 5 (Accelerator) then the experiment will fall apart, as the prevailing condition that Accelerator is the strongest esper would be nullified.
Accelerator is later seen in another fight against Misaka 10032, where he tells her that he wants to gain a status that is beyond simply being the strongest in Academy City - he wants to attain Level 6, so that challenging him would be an unimaginable thought- even a sin. They are interrupted by Kamijou Touma who challenges him to battle just as Accelerator was about to finish the clone off. Initially seeing Touma as a weakling, he later panics and is confused as to why Touma was capable of blocking his abilities. Eventually, Touma is able to beat Accelerator using his street fighting skills, exploiting Accelerator's physical weakness (due to the nature of his power, he always defeated his foes with a single hit and never took damage, he therefore had no experience in hand-to-hand combat as his opponents could never reach him), and ending the experiment.
Three Stories ArcEdit
- Main article:Three Stories Arc
After his defeat, Accelerator notices that something has changed within him as evident by the lack of his usual aggressive behavior when confronted by delinquents, who now believe that Accelerator is actually weak, attacking him with increasing frequency. During one of his trips to buy coffee, Accelerator meets a hooded figure who had been following him for some time. After an awkward meeting, the figure identifies herself as Misaka Serial Number 20001 or better known as Last Order. She explains that she was released from her incubation tank prematurely and requests for Accelerator's help to contact the researchers, to which he nonchalantly refuses. Despite the rejection, Last Order continues to follow Accelerator where they discover that his room has been severely vandalised by delinquents. Although Accelerator urges her to think twice about staying in his destroyed home, Last Order still persists in accepting his hospitality as she wants to be with someone. This baffles Accelerator, though he allows her to stay.
The next day, Accelerator brings Last Order out to a restaurant for a meal, where he notices Amai Ao, a scientist involved in the Sisters project, acting suspiciously before fleeing after being spotted by Accelerator. Here, Accelerator confronts Last Order over her care-free attitude towards him, reminding her of his role in the Level Six Shift. Here, Last Order gives a psychoanalysis of Accelerator based on the actions he committed and deduces that Accelerator did not join the Experiments willingly, therefore she bears no grudge against him and actually thanks him as his existence allowed the clones to be created. Accelerator refutes her claim, stating that his continuous killing of the Sisters proved that he did not care for their lives, but Last Order points out that he attempted to communicate to the Sisters in a harsh manner so as to discourage them from fighting him and believes that he never wanted to hurt them. Slightly disturbed and annoyed from her lecture, Accelerator leaves Last Order in the restaurant although he shows some concern over her as she nearly passes out after their talk.
Walking through the streets, Accelerator finds himself at one of the warehouses used in the Sisters project, confused by his intentions to help Last Order. Inside the facility, Accelerator meets an old acquaintance of his, Yoshikawa Kikyou whom he asks for equipment and instructions to help Last Order. Here, Yoshikawa reveals that Last Order is actually the Administrator of The Misaka Network and Amai Ao has inserted a virus that will cause the Sisters to rampage out of control. Unexpectedly, Accelerator decides to recover Last Order in order to save her, but is too late as Amai Ao abducts her. However, Accelerator easily locates and incapacitates Amai Ao before securing Last Order. Suddenly, the virus within Last Order begins to prime itself for activation, surprising Accelerator and Yoshikawa who initially thought the virus would activate much later. Despite Yoshikawa's insistence, Accelerator refuses to kill Last Order and instead uses his Vector Change to control Last Order's bioelectric frequency and delete the virus from within. Accelerator focuses his entire computation abilities on deleting the virus which leaves him defenseless against a recovered Amai, who shoots Accelerator in the head. Despite Amai's shot, Accelerator manages to erase the virus and save the world and the Sisters from each other. Accelerator is brought to a certain hospital where Heaven Canceler tells Yoshikawa that the bullet fragments in Accelerator's skull have damaged his computation, mobility, and language abilities, effectively crippling him. Accelerator is forced to wear a choker-style electrode that connects him to the Misaka Network. This is used to compensate for his language, mobility, and calculation skills as well as his Esper Ability, although it has been stated that he only has less than half of his original processing ability, thus making him weaker. Also the choker has a rechargeable battery that keeps the terminal on the choker running, but the energy consumption of the choker differs greatly when used normally (a few days) to when used for his vector calculations (15~30mins upgraded).
Kazakiri Hyouka ArcEdit
- Main article:Kazakiri Hyouka Arc
In the anime adaptation, at the end of the arc Accelerator is seen sleeping in a hospital room with Last Order sleeping on a chair next to his bed.
Tree Diagram Remnant ArcEdit
- Main article:Tree Diagram Remnant Arc
Accelerator sneaks out of the hospital he was in to destroy the remnants of Tree Diagram, as a request by Last Order. He meets with a weakened Musujime Awaki who carries a remnant of Tree Diagram, irritated by the fact that he was forced to help out and his opponent was only a "stupid looking third rate" like her. Although Awaki is aware of Accelerator's weakened state and believed that she could match him now, Accelerator is unperturbed. Simply replying that his being weaker doesn't make her any stronger, he quickly defeats her and destroys the remnants of Tree Diagram, ensuring that it will never be rebuilt.
Academy City Invasion ArcEdit
- Main article:Academy City Invasion Arc
Accelerator, along with Last Order, leaves the hospital and moves into the apartment of the Anti-Skill Yomikawa Aiho as a request from her friend Yoshikawa Kikyo. Accelerator was reluctant since having him next to her would put her and others in high danger because of his enemies.Later on, after a short nap, he realizes Last Order has gone missing, prompting him to search for her. During that time, he bumps into Index, not knowing her connection with Touma, and even treats her with food - costing him all of his pocket money. They separate as Index spots Touma amongst a crowd and runs towards him, just as Last Order runs to Accelerator. Because he wasn't in the mood to search for her again, he tells Last Order to keep quiet but she trips, almost crying because of some scraping on her hands and knees. Accelerator goes for some medicinal bands at a nearby pharmacy, but upon returning he is hit by a black van from the black-ops known as Hound Dogs, who were under the orders of Kihara Amata, the man who discovered his powers. Amata's orders were to retrieve Last Order, but he decides to beat Accelerator to a pulp first, as he knows his powers inside out, including how to turn Accelerator's redirection against him and even negate his wind-based powers. In desperation, Accelerator blasts the captive Last Order away from the Hound Dogs with a wind blast, then manages to escape Kihara and his men by way of a chance distraction by an aloof Index, who came looking for him to return a pack of tissue he gave her. Just as Kihara launches a homing missile at Accelerator and Index's getaway van, he is interrupted by Vento of the Front's arrival, letting the two escape.
Accelerator, considering Index dead weight, decides to drop Index off at the hospital where Heaven Canceler works, misleading her into thinking he needed a replacement battery for his choker electrode and having her fetch it (no replacement exists). He then sets off to kill Kihara, crush the Hound Dogs and save Last Order, but decides to just focus on saving Last Order after a jarring conversation with Heaven Canceler, who reveals to him that he knows far more darkness than even Accelerator has encountered. Accelerator attempts to shake off the pursuing Hound Dogs temporarily, but eventually resolves to force Kihara into re-evaluating his priorities away from Last Order (and towards eliminating him) by wiping out his Hound Dogs. Unfortunately, after wiping out two whole squads with psychological tactics alone (conserving his remaining 7 minutes of active esper power), he snaps and goes all-out at a taunting, fleeing Hound Dog who manages to seek aid from two surviving Anti-Skills, and ends up on the Anti-Skills' wanted report.After receiving a call from Touma (whose voice he fails to recognize) regarding Last Order's whereabouts, he gets a lead from a call from Kihara, who now has Last Order captive, and breaks into one of Academy City's board directors' homes, digging up Kihara's (and Last Order's) whereabouts. He attacks Kihara's compound, but runs out of battery charge without being able to bring him down, yet ultimately kills him as he first "awakens," having an epiphany right as he was to be finished off. This is symbolic because the god that Accelerator`s power just happens to resemble is Osiris, the Egyptian god of the dead.
Document of Constantine ArcEdit
- Main article:Document of Constantine Arc
Academy City put Accelerator in charge of the operation to subdue the problem with Terra of the Left in Avignon. Hundreds of HsPS-15 AI suits and eight HsB-02 planes were sent and proceeded to tear apart the city, using speed to create vacuums after the plane's path and sending iron sand into the vacuum to make it explode. Accelerator tells them to change their plans to bomb just the Palais des Papes instead of bombing whole Avignon, the order being approved when the pilot he was with checked with the higher ups.
At the end, Itsuwa sees Accelerator in the middle of the scorching flames caused by a HsB-02. Accelerator is speaking with one of the higher ups of Academy City on the phone, telling them to send troops to come search for Terra's corpse and to run DNA Tests to see if he's really dead. It is unknown if he notices her or not as she is covered by the steam. Accelerator leaves soon after to a deeper part of the palace. Itsuwa says that she finds Accelerator, who is able to stand in the middle of such flames, to be even more terrifying than Terra.
Battle Royale ArcEdit
- Main article:Battle Royale Arc
After Accelerator joins GROUP he finds himself involved in a fight between the underground organizations where he fights the second strongest Level 5, Kakine Teitoku. When his fight was about to end, he pointed a gun at Kakine and almost pulled the trigger, but Yomikawa ran in and interfered. She told Accelerator that he doesn't need the gun, and that she will do whatever it takes to pull him out from the darkness. Accelerator was determined to eliminate anyone that gets in his way in order to protect the ones he wants to protect, including Yomikawa herself, but Yomikawa was eventually able to take the gun away from him because deep inside, Accelerator still hopes for the light. After Yomikawa took the gun, Kakine impaled Yomikawa with his wings first, then pressed her against the ground with an invisible attack, saying that it wasn't that easy and that he and Accelerator didn't need her help. Kakine also did this out of spite, thinking if Accelerator, someone that even surpasses himself in 'Evil', is nothing more than a person that still has attachments on the side of Light like a weak, normal person, then what does it make himself who has lost to that kind of halfhearted "evil?" That's why he tried to kill Yomikawa, for the sake of his pride that if he is to be defeated then at least let the one that defeated him be the ultimate "evil."
Then, Accelerator went berserk, full of anger, frustration and hatred lamenting that he still can't protect the people he cares. Then he truly "awakens", gaining Black Mist Wings, and proceeds to utterly destroy Kakine Teitoku, mercilessly dismembering him. Soon, Anti-Skill surround Accelerator and despite a wounded Yomikawa's protests, are prepared to attack him due to the uncontrollable danger he was presenting. However, Last Order finally finds Accelerator and approaches him. Here, she calms him down by stating that he no longer has to repeat the tragedies that plague his life and reassures that everything will be fine. The Black Wings, which were presenting the anguish he felt, attempted to obliterate Last Order but Accelerator's willpower prevents them from doing so, determined to protect the last hope he held in his heart, causing the Black Wings to dissipate. Exhausted from the experience, Accelerator collapses into Last Order's arms before passing out.
Stated in the novel that the wings are an expression of his AIM field, similar to Kakine's own "Dark Matter." Crowley even comments offhandedly to Heaven Canceler on the process of Accelerator's awakening, stating that "The process of downloading the data of the AIM field onto the vector controlling device (Accelerator) has finally been completed." This seems to imply that turning Accelerator into an Artificial Angel has been Crowley`s plan all along, and goes hand in hand with creating a Level 6, a being equal to God.
- Main article:DRAGON Arc
After the aftermath of the events in Volume 15, he is hired along with the other members of GROUP to take on a rogue group called "Spark Signal" in Academy City. After Accelerator wipes out their main force, they find info on DRAGON, a mysterious force. When Accelerator tried to get close to the 5 remaining members of Spark Signal to gain information on DRAGON, the bodyguard of Director Shiokishi killed the remaining members and told Accelerator to stay out of Shiokishi's businesses if he doesn't want to regret it. He runs into Takitsubo Rikou lying in a bad state when Hamazura Shiage, who misunderstands Accelerator's intentions, arrives. Shiage tries to fight him but doesn't stand a chance, yet Accelerator leaves them both after watching how determined Shiage was and because Rikou caused him to feel compassion.
After he left the place, GROUP negotiated with Director Oyafune to help Accelerator take down another director that was after GROUP. When Shiokishi was defeated, he remarks he 'unfortunately' does know the truth about DRAGON, and it might have been better if he didn’t know in the first place. When GROUP asked him what DRAGON was, he replied “DRAGON is everywhere" and then everyone else, including GROUP save Accelerator, got knocked unconscious. When the director exclaimed the one behind them that did this wasn’t Fuse=KAZAKIRI like he thought, he was knocked out as well, with a voice somewhere saying "of course not, it's DRAGON."
In front of Accelerator appears Aiwass, a higher dimensional super-being, the true author of the Book of Law and Crowley's mentor summoned to the physical plane of existence by Aleister himself. Aiwass keeps Accelerator conscious out of curiosity. Aiwass then explains that when AIM entities like herself (although Aiwass' gender is unspecified, it appears female) are manifested, Last Order is heavily strained and may die/collapse if left untreated. Accelerator got cut in half after he used his cane to jam Aiwass's AIM field and foolishly tried to attack her. However, in the end he shut down the Misaka Network to weaken Aiwass, shooting the core, but still Aiwass was unscathed, with the additional defenses programmed in by Aleister. Aiwass said, "That’s such a pity," before defeating Accelerator.
Accelerator headed to Russia after Aiwass suggested not even Heaven Canceler can heal Last Order. The only one that can save Last Order now is "Index Librorum Prohibitorum." Accelerator crushed his cellphone, erasing his last link to Yomikawa, Yoshikawa, GROUP and anyone else he ever had a link with and then began his search for Index to help Last Order from her weakening state, since she managed to save Last Order last time when she last collapsed while sustaining Fuse=KAZAKIRI.
World War IIIEdit
- Main article:World War III
October 30th.While riding a train carrying military supplies to Russia, Accelerator spends a few moments talking to a barely conscious Last Order. This conversation is cut short when 10 unmanned Powered Suits attack the train, Accelerator covers Last Order's eyes with a handkerchief before engaging them. It seems the goal of the machine soldiers wasn't Accelerator or Last Order, but various parchments with spells on them. Accelerator easily annihilates the forces Academy City sent troops for and then studies the parchment.
As of Volume 20, he is currently in Russia, where he has a brief encounter with some Russian mages, and some of Academy city's new streamlined, high-speed power suits. It is also during this encounter where we learn that his ability not only works on magic (although incompletely, as the magic is dissipated instead of redirected) but also on teleportation as well. Accelerator also has an encounter with one of the new Level 4 Misaka clones, dubbed Misaka WORST, where he learns of Crowley's plans to make a new network with the new line of clones, and eliminate Last Order who has now become obsolete. Despite being far more powerful than the clone, he is at a disadvantage since he cannot bring himself to hurt another clone after the Level 6 experiment, and sustains minor injuries. Misaka WORST then proceeds to taunt and mentally traumatize him, telling him about the Sisters' hatred of him, and how Last Order's emotions for him are false. She ultimately forces Accelerator to choose between protecting Last Order or upholding his vow to never hurt another Misaka clone.
This causes Accelerator to have a mental breakdown, losing all reason when he awakens and goes berserk. He proceeds to beat Misaka WORST into the ground, becoming even more cruel and barbaric than his old personality from the days of the experiment. Despite having lost all faith in humanity, he still saves her when she attempts suicide as a way of showing the scientists who doubted him, that he does have the capacity to save people (alternatively, he only did it to annoy the ones who thought up this plan, telling them they've failed in their calculations). He then continues his rampage in front of an injured Misaka WORST, who notes that being around by him and seeing this state causes her to feel a lot of fear and regret for pushing him too far.
Later he sees Kamijou Touma passing in a military convoy along with Elizerina's forces. Accelerator, angry that the supposedly "invincible hero" is not willing to help Last Order in her time of need, attacks him out of the blue. He starts by causing a massive explosion that knocks down Touma, who miraculously survives. Accelerator then realizes that frequent battles must have given Touma some kind of supernatural instinct, an incomplete form of precognition for sensing AIM fields in some way, and thus reacting to the minute movements of his opponents.
Touma then proceeds to get up and exchange words with Accelerator, showing that Accelerator both idolizes and is jealous of Touma and his heroic personality because he cannot attain such a personality himself. Touma rebuts Accelerator's hero-villain ideals, stating that heroes are not necessary and telling Accelerator to realize that choosing good and evil and being heroes and villains are all unimportant - what really matters is the desire to protect someone.
Accelerator then summons 100 wings and strikes Touma with them, only for Touma to use his Imagine Breaker to grab one of his empowered wings and throw Accelerator off-balance. Touma then proceeds to punch Accelerator in the face, knocking him down. The second defeat at the hands of Touma triggers another big change in Accelerator's mentality, as Touma shattered Accelerator's ideals and the power of the black wings that he gained by submitting himself to the dark side. Accelerator's villainous rationale that had been his pillar of support was "killed" by Touma.
Touma also uses his Imagine Breaker to stabilize Last Order, although it was only a temporary fix, and then leaves him a note informing him to look for "Index Librorum Prohibitorum" to inquire about the lambskin Touma saw Accelerator had, though Accelerator mistook it for a note telling him to look for Index if he wants to save Last Order, since he heard about Index from Aiwass. Accelerator is later seen in a convoy traveling along with Elizarina's troops searching for a way to heal Last Order.
He currently has possession of a lambskin document sought after by Academy City, and may turn the tide of the war. He acquired it from a Russian military convoy he was hiding in, and when Academy City forces attacked, he thought they came after him while it was for the lambskin document. Accelerator then took the report, thinking of using it as a bargaining chip for Last Order's safety - if Academy City wants it so badly they would mobilize the same forces they'd use to fight a Level 5 esper, then it should be useful.
In Volume 21 the lambskin is revealed to be the last piece for Fiamma to fill the gap between Index's knowledge of all magic and allow him to access magic of Divine origins. Because of this, Gabriel attacks him and he is forced to defend himself. He and Fuse=KAZAKIRI, after initially fighting each other, were able to defeat Gabriel due to the combined efforts of Acqua of the Back and Kamijou Touma; taking away 50% of Gabriel's power and removing Gabriel from Fiamma's control respectively.
To save Last Order, he and Misaka WORST analyzed Index's song that was stored on the Misaka Network, using his vector abilities to understand it and perform the spell. He was severely damaged by it, but completely cured Last Order. Soon after, Fiamma blasted a huge amount of telesma from the Star of Bethlehem as a last ditch effort to complete his goals. Sensing the attack coming, Accelerator fully "awakens," changing his wings from black to white and gaining a halo over his head. After saying goodbye to the recently cured Last Order, he went to intercept the telesma. He succeeds, and was later picked up by an Academy City retrieval unit. After the retrieval, he forcefully negotiates with Academy City to free everyone from the darkness.
Shinyaku Toaru Majutsu no IndexEdit
- Main article:Freshmen Arc
Accelerator reappears after the war with Last Order and Misaka WORST all living in Yomikawa's apartment with an honored deal of releasing those on the Dark side of the Academy with the Board of the Directors. This peace didn't last long as members of the "Freshmen" wanted to eliminate him and Shiage out of jealousy. The attack ends with the return of Touma and the final events of the first novel have him, Touma, and Shiage conversing on Magic and the state of World War III.
- Main article:Homecoming Arc
The meeting of three protagonists is moved to Touma's house as suggested by Leivinia Birdway. After temporarily separating from Touma, who got drunk, Accelerator is surprised to see one of his former teammates Musujime with Touma and a dozen other girls.  After mid-way through the discussion on Magic, he is surprised once again on meeting another former teammate Motoharu, who gives thanks for being released as a spy for Academy City, only to be annoyed at Last Order and Misaka Worst appearing out of nowhere. 
When Radiosonde Castle appears in the sky over Academy City, Accelerator uses his newly acquired knowledge of magic and Feng Shui to locate the crystal "transmitter" which was calling the flying fortress. 
Ichihanaran Festival ArcEdit
- Main article:Ichihanaran Festival Arc
Eve of the FestivalEdit
Accelerator first appears in Aiho's residence, enjoying his own time relaxing. Here, he is called by Kikyou to deal with Last Order to get to dinner, as he is her guardian, as Last Order was too busy playing a video game with the Misaka Network. Kikyou reminds Accelerator that she cannot stay like a housewife in training, to which Accelerator asks if she has found work somewhere. Kikyou says that she is still making preparations, and states that she has been invited as a special lecturer in a college of science, though it is only temporary as she wants to get back into college. Kikyou says that she wants to be a teacher, and states her enthusiasm into becoming a Student Keeper.
Then, Kikyou remembers that she doesn't have green onions for the flavor of her mizutaki, to which Last Order, who was taking a break from her video game, says that she would be willing to buy them. Seeing this, Accelerator is then told to go deal with her. As Accelerator argues with her regarding which one between him or Last Order holds the reins in their relationship, they fail to notice that Last Order has stopped shouting and has gone off on her own. Kikyou then tells Accelerator to take care of it, much to his irritation.
Accelerator jumps around the city trying to look for Last Order everywhere. Finding nothing, he and Kikyou, who was forced to help him find her as well, head back to their apartment. Much to their surprise, Last Order is already there, eating some chocolate. Last Order explains her little sojourn with Fremea Seivelun, then their eating competition, which reminds both Kikyou and Accelerator that they have yet to eat dinner.
Day of the FestivalEdit
Accelerator first appears declining Kikyou to have him deal with Last Order's obstinate attitude on eating her breakfast. As Last Order continues talking about the festival, Accelerator asks her what her plans are about having Last Order go to school. Kikyou gives a researcher-like response, that since Last Order shouldn't technically exist, she cannot go to school, however, she can get all the education she needs through the Misaka Network. Falling silent, Kikyou asks what's up with Accelerator, to which he simply states that she should be prepared to overcome that part of herself. Accelerator then tells Last Order to hurry up and finish eating because they will head out, making an excuse that he just wanted to find some winter boots, and that if there are any schools nearby they can make a stop. Both Kikyou and Last Order fall silent at their surprise, but Last Order breaks it by trying to dash towards the door, prompting both Accelerator and Kikyou to restrain her.
Accelerator, Kikyou, and Last Order go out to enjoy the festival, and come upon Fremea Seivelun, Hamazura Shiage and Takitsubo Rikou. While there, Fräulein Kreutune finally comes upon Last Order, and tackles Shiage down just to get to her. She is promptly met by Accelerator, who comes between her and Last Order. Accelerator launches her far into the air. However, Fräulein is implacable and approaches again. This time however, before Accelerator could attack, a shell from the revived Kakine Teitoku's Rhinoceros beetles bends her body, allowing for Accelerator to launch her far away. The shell caused a panic in the area, leaving only Accelerator, Last Order, Yoshikawa Kikyou, Hamazura Shiage, Taikitsubo Rikou, and Fremea Seivelun together. When Accelerator looked towards the direction where the shell was fired from, he sees the beetles surrounding them; Teitoku speaks using their wings' vibrations. Teitoku asks Accelerator if he remembers him, to which Accelerator answers that it's a voice he doesn't bother to remember. Teitoku says to Accelerator that he doesn't care about anyone else, even if they get hurt, as he will only focus on him, much to Accelerator's irritation, as he tries to find a way to protect or not involve others. Accelerator looks towards the roof where Teitokiu is located. To his surprise, several human figures accompany Teitoku, his own forms. Teitoku reveals that he is able to reproduce his own organs, even his own brain. With that, Teitoku tells Accelerator how he made the beetles, but calls them more like cyborgs. He then tells him that the battle will begin, taunting him and then saying that his strength will level him up infinitely. Accelerator then shot out towards Teitoku, leaving a hole behind him and the others so they can escape.
Although he managed to eliminate 300 Dark Matter Teitoku replicas in only 15 minutes, with the battle getting prolonged, Accelerator was well aware of the fact that the battery power for his electrode was running low. Accelerator has created nonsense calculations in order to throw off Teitoku's predictions about him; at the same time, Accelerator takes a power cable from an overpass, and uses the electricity there to recharge it, careful not to overcharge it. With that, Accelerator predicts that his nonsense calculations should have reached Kakine, and that he should be able to beat him if he based his answer off it, unaware that Teitoku knows that they are nonsense calculations. Both Accelerator and Teitoku predict each other's thoughts on what they will do next.
Teitoku leads Accelerator to the underground passageways of the lowest level of the multi-level overpass. Accelerator calls Teitoku pathetic, leading him to ask him how far he has come after much has happened to him. Accelerator still calls him pathetic, saying that if he truly did gather everything for what he lacked, then he shouldn't care about that issue. Accelerator said that he had enough, and that despite all Teitoku had done to gain his power, he is still pathetic.
However, Teitoku then references the location they were in. He asks if the location they were in is familiar to him, but Accelerator could not answer. Laughing, Teitoku reveals that this was one of the stages for the Level 6 Shift, where Accelerator once mercilessly killed Sister clones. Before Accelerator could react, Teitoku has already created a change. Before them were several Misaka clones, speaking, acting, and moving like the Misaka clones that was there when Accelerator killed them an uncounted number of ages ago. Teitoku reminds him that they aren't actually them, as he forced his will upon them, turning towards Accelerator. He tells Accelerator that he cannot completely fix someone who has died, nor he can make something completely identical. He explains to him that he uses his Dark Matter to take information from an area, like a form of Psychometry, and give the information form.
Hesitation comes upon Accelerator, and Teitoku notes that it is actually working, much to Accelerator's anger. Teitoku relates on how esper powers are controlled using high level calculation ability, even unknowingly, and that throwing it out of order can be useful, like making him lose his reflection. However, Teitoku notes his interest in seeing those wings, and asks Accelerator to at least make himself be worthy of testing his ability. The Dark Matter Misaka clones are ordered to attack him, something that should not be a problem for him. However, instead of taking them down head-on, Accelerator dodges their attacks. It was due to him not wanting to hurt them, as they reminded him of his sin. Seeing his actions, Teitoku says that he is full of openings. He turns his arm into a giant wing, and shoots out sharp feathers towards him, hitting the Sisters on the way like spears. Accelerator was unable to evade in time, and his thoughts were unable to fully implement his reflection. He is wounded by one of the spears and thrown into the air, though he managed to break his fall. Before him, Accelerator's anger boils, as the Sisters try to enact their orders despite being torn apart by the spears Teitoku has shot out. Accelerator could not help but remember the sins he has committed, as Teitoku continues to toy with him.
Teitoku tells Accelerator that he did much research regarding him, and that even though it looks like he has atoned for what he did, and that Last Order has forgiven him, it does not mean that he has been completely forgiven. Continuing, he tells that despite him viewing the Sisters as an aggregate whole in the Misaka Network, he also believes that the Sisters' individual personalities should also be recognized, that should mean the overall will that has accepted doesn't matter, as "only the one who was killed can understand the feelings of the one who was killed," and that, there is no longer any way he can determine if he has truly been forgiven. However, Teitoku tries to trick Accelerator even further, telling him that the clones that he has formed are the final piece that would allow Accelerator to determine what those he killed thought, but also tells him that no one would know of his sins if he killed them here.
His words pierce through Accelerator, hurtling his mind into disarray, and weakening his calculations. Not only was he unable to control his power, but he was not even properly carrying out the calculation. And with that, Teitoku attacks. However, a beam of heat and light pierces through into the underground passageways, killing one of the clones. It is Mugino Shizuri, who has come to the lowest depths. She berates Accelerator for his actions, enraging him. She tells him that he is being angry at the wrong person, and references Teitoku's words on how "Only the one who was killed can understand the feelings of the one who was killed," is correct but states that the clones Teitoku made in here aren't really them. She continues that it is not the likes of them, people who have killed others, to even begin to understand what the dead feel as it is not their purpose. She states that Accelerator is incredibly naive to fall for Teitoku's tricks, and asks if he thought that they might come back to life and that his crimes for killing them would be undone. She says that she has read about the clones, and that his reasons for killing them was not worse than her killing others for no reason. She tells him that they are both going to hell, but there are things he needs to do before he goes. She asks what he will do, telling him that she doesn't care if he allows himself to get killed, or retrieves the dead's dignity and peaceful rest from the desecrater before him; it is his choice.
Accelerator acknowledges this, regardless however, the clones before him are the final proof that those he killed ever existed. Shizuri replies that it is all the more reason, and if he finds it acceptable for someone to steal and control the dead, then he should just let himself be killed as she will take care of everything. She then feels uneasy and tells Accelerator that he has to dirty his hands to give the dead a clean end. She references what Teitoku said again, and says that only the living can act based on their feelings for the dead, and rejecting that and running way is neither being honest or pacifistic, but plain cowardice. And with that, Accelerator is released from his stupor and tells her that he will destroy, that he will be the remnant to prove that those people he killed really existed.
Teitoku finally reacts after listening to them, and asks if they will stop thinking how the dead feel and stop thinking about it. Shizuri tells him that he will never understand, for he is someone who puts words in the dead's mouth for his own benefit and runs away from his feelings regarding the dead himself. She tells him that he is pathetic even though he is powerful, and it would've been better if he had remained dead, for he would've been merely the esper that defeated her. Then, she tells him the reason she was in there with them. On how someone who pretended to be Frenda attacked her last night, and suspects him for it for he was the biggest factor from the dark side of Academy City active at that time and the interest in playing with the dead was the same. She tells him that she doesn't know what his purpose was with what he did, and tells him that she will make him pay for disturbing her grave.
And with that, their battle begins. Shizuri used her beam on Accelerator for his use, redirecting it to all the false clones Teitoku created at once, destroying them. Here, Accelerator finally decides to no longer chase after Touma, and focus on him. He will take a different path from Touma, where he could do things Touma could not. Accelerator directs his attention towards Teitoku, and uses his vector powers to destroy all the Dark Matter spears he created. As he twitched, Shizuri fired at him, obliterating the top half of his body and most of his legs. However, Teitoku appears upon a wall, saying that he can recreate himself. Shizuri asks if he moved his flesh and blood organs into the floor before her attack. Teitoku redirects the question, and hints many possibilities now that he can replace and create practically anything with his power.
Accelerator does not care however, ripping apart the countless spears and redirecting the signals in the center point in the puddle, but to no avail, as Teitoku states the network of his Dark Matter expands and information is sent faster without direct wiring than he can destroy it. Despite this, Accelerator continues to try and destroy his Dark Matter, as Shizuri continued to assist him. Teitoku then asks how much battery time Accelerator has left, and is curious about the wings that no theory can explain. Teitoku just brags on how time is running out, and that he has no problem taking down Shizuri. They continued attacking destroying his head, but it is of no avail, as he tells them that he simply has an infinite supply of Dark Matter, and his inspiration is boundless, telling them that to reach him, they need to climb over the wall of infinity that continues on eternally. He then shoots out countless Dark Matter spears towards them.
Teitoku continues his assault, but time is running out, and Teitoku simply taunts them as his Dark Matter attacks continue to shoot out. But then, something happened; he stopped. Shizuri becomes curious, threatening to kill him. But Teitoku does not answer, as he too is confused. He then asks what Accelerator did, believing him to be the culprit. Then, Accelerator realizes something. He tells Teitoku that this was the effect of him being "infinite," and tells Teitoku that it wasn't him.
He did not know, but Beetle 05, the rogue beetle that Teitoku ignored, was beginning to take over. As the system begins to transfer authority to Beetle 05, Teitoku begins to crack, who cries on how it is not possible for a power that he brought to betray him. Accelerator then tells Teitoku that it is no longer matters who was the first Teitoku, as he obtained the infinite. Shizuri too began to understand. She laughs at his problem of being too powerful, saying that when a network made up of flexibly replaceable equipment has a portion become isolated from the rest, the isolated portion becomes a small network of its own. Accelerator concludes that the one who stopped Kakine Teitoku was now the Kakine Teitoku. Accelerator is impressed on Dark Matter's capabilities, and mocks him for being unable to wield it. Shizuri however notes that he might not be the core Teitoku as he had scattered his mind over the system, and the one before them was closest to the surface, though it says of nothing that what showed itself in the surface was the true nature of Kakine Teitoku. Shizuri then asks if they were just battling the outer layer of his mind, and states that it wasn't easy doing it. Here, she is impressed by Kakine Teitoku, being not a normal person, but not the one before her right now.
Slowly, despair overtakes Teitoku and slowly more cracks form. Accelerator comments on how there will probably be nothing left to prove that he was here, and even if a massive amount of data is left concerning Kakine Teitoku, it will not refer to him. In his darkest hour, Teitoku recalls Takitsubo Rikou being part of the group when he attacked them for the first time. He also recalls that she had the ability to track others' AIM dispersion fields, and that she also had the hidden possibility of using others’ AIM diffusion fields to distort their Personal Realities. A person he deemed to have been capable of becoming the eighth Level 5. There, Teitoku realized that she might be the one, consciously or subconsciously, that had incited the change in Beetle 05. Teitoku is enraged greatly. He shouts his fury in that underground passageway with only Accelerator and Shizuri as his audience. Accelerator however, had enough, and pierced his center of the thing before them, completely shattering it, and the Dark Matter dissolved into the air, leaving nothing behind.
Accelerator comments that it is over, but Shizuri just shrugs, saying that they still have a long way to go for people like them. While leaving the underground passageways, Shizuri asks if he intends to do anything about Fräulein Kreutune, to which Accelerator replies that he doesn't care, but is intrigued by the fact that someone he knows wants to protect her and risked herself to stop him from killing her. As they got out into the open, Shizuri sees Fräulein eating something which she presumes to be a human brain, and witnesses Accelerator's near rampage as he produces wings after he presumes it was Last Order she was eating. However, Last Order calls out to her, proving that she is alive and well. Fräulein was eating a candy brain made out of the spare ingredients of Cendrillon's body, as conceived by Kamijou Touma.
After the events of the arc, Accelerator returns with Last Order and Kikyou, considering not telling what had transpired during the day to Aiho. Accelerator is deep in thought, feeling restless about the convenient solution that has transpired during the events, as well as the secrets of Academy City, thinking that he could sacrifice himself and expose the rottenness of the City's core. As Last Order enters the room Accelerator is in, he discovers Last Order has been possessed by an existence which he refers to as the "will of the whole of the Misaka Network". Here, the existence berates Accelerator for thinking that he could go the easy way out, destroy the peaceful life he has, and then go to hell once everything is put in order, by throwing himself into a fight to approach the secrets of Academy City. The existence tells that his anxiety regarding forgetting what he needs do by growing relaxed in his new life is unfounded. As he is a monster, the existence tells him that it is most comfortable for him to have an easy conflict, violence, and victory, that it is only natural for him. However, the existence states that his calculation power was not loaned to him just so he can take the easy way out.
The existence states that he must struggle for someone's sake, struggle in the way that is most difficult, and threatens him that if he took the easy road and become a monster, then the existence will throw him into a hell several sizes larger than his imagining. The existence concludes that despite leaving Last Order and Misaka Worst with him, the existence is much more interested with Touma and is concerned for his well-being as of late. With that, the "e-mail" ends and Last Order collapses to the floor.
Agitate Halation ArcEdit
- Main article:Agitate Halation Arc
Accelerator first appears near the end of this arc. Because of the movements of the city's darkness which led to these events and presumably also being one of the "heroes", Accelerator arrives at Learning Core at the scene of action. He first flies at high speed with tornadoes to the spot with the largest concentration of heroes and not far away from where Mugino Shizuri was fighting. When he lands, he blows away about 1000 people, yet nobody dies because he made sure with his supreme vector control. He acts a bit dissapointed when seeing he defeated them so easily, and asks whether they thought he would only act if "that brat" was involved. He then adds that when the darkness of the city makes a movement to this extent he cannot ignore it. Yet, after intercepting information about the events with Tsuchimikado Motoharu, another reason for him is making a preemptive strike in case the flames spread to him. Afterwards, Accelerator spots Touma, realizing he had escaped the shockwave created by Accelerator's arrival. He asks the boy if he knows what he has to do, which Touma confirms. Accelerator tells him to go, as he is not the protagonist here; Touma is. While Touma gets away, he warns Accelerator that the heroes are controlled by the Agitate Halation Project, but Accelerator only asks who does he think he's talking to. After Touma disappears, new enemies surround Accelerator. They noticed the underground route Touma has taken and are now planning to use it to go and save Fremea. Accelerator smiles in scorn, and claims that he will use his bloody hands to test whether the "heroes" are worthy of that title.
Toaru Kagaku no RailgunEdit
- Main article:Sisters Arc
Accelerator first appears in Toaru Kagaku no Railgun, where during another session of brutally killing a Misaka clone, he meets an enraged Misaka Mikoto who tries to get revenge on him after she witnesses him killing Misaka 9,982. However, Mikoto is powerless against Accelerator due to his abilities. He later figures out that she is the original Misaka Mikoto and becomes disappointed that although both are Level 5's, Mikoto is very weak compared to him, and, wanting to speed up the experiments, opts to kill her. He is prevented from doing so by the arrival of several Misaka clones, who tell him that he should follow the protocols; killing Mikoto would cause discrepancies in the calculations. Accelerator accepts this explanation and leaves Mikoto alone after telling her his name.
In the Railgun Manga, Accelerator appears in a daydream by Nunotaba Shinobu that hopes that by putting "fake emotions" into the Sisters, she could possibly move his heart. This is because she apparently believes that even he wouldn't kill the Misaka clones who would be crying because of their emotions in that hypothetical situation. She is one of the few people who in addition to Last Order seem to believe that Accelerator would stop the experiment if he realized that the clones behaved like/were actual humans.
Accelerator reappears briefly in his battle against Misaka 10031, where Mikoto accidentally sees how he reverses the clone's blood with his vector powers on a monitor. Later, he reappears in another experiment with the clones; this time he has to defeat Misaka 10032, but is interrupted by the arrival of Touma. Many of the scenes featured have the fight featured in Accelerator's perspective and shows as well the beginning of the Experiment with a younger self. Right before Touma delivers the final punch, he questions what he has been doing this whole time.
Silent Party ArcEdit
- Main article:Silent Party Arc
A still recovering Accelerator briefly appears on September 2, while undergoing a drip lying down on his hospital room's bed, looks at the sky from the room's window together with a Last Order seated on a chair next to his bed.
Daihasei Festival Arc (Railgun)Edit
- Main article:Daihasei Festival Arc (Railgun)
An already crippled Accelerator is first seen wandering an alleyway when he is approached by a liaison, whom Accelerator apparently knows, and is aware of his connections to the Level 6 Shift. The liaison, somehow asked by the Daihaseisai Student Committee, which was tasked by the Board of Directors themselves, to have the Level 5s promote the Daihaseisai. Accelerator being the number 1 ranked esper is a foregone conclusion. Accelerator spares not a moment of time towards the liaison, telling him that he is not interested in anything that he is offering, attacks him, and warns him to go away. Before the liaison can even start telling him that he is wanted in the Daihaseisai, he is attacked by Accelerator, who leaves, telling him that he is too busy taking care of the brat, Last Order.
Toaru Majutsu no Index Movie: Miracle of EndymionEdit
- Main article:Toaru Majutsu no Index Movie: Miracle of Endymion
Accelerator appears in two trailers from the upcoming theatrical release of the movie.
In the movie, Accelerator appears in the hospital, still recuperating after getting shot in the head. Last Order later gets information relayed to her from the Sisters through the Misaka Network after overhearing Touma's conversation, that the there is great peril upon Endymion. Accelerator is annoyed by her noise-making and tries to go back to rest. However, later, when the need was dire, Accelerator arrives at the base of Endymion before one of the explosive bolts, most likely after Last Order was relayed information to her that it must be destroyed in order to "terminate" or "purge" Endymion. Accelerator is once again annoyed by this, to which Last Order says that they have come because the world is in danger, though Accelerator replies that he does not care for such a thing. In the end, he destroys the explosive bolt, deeming it good exercise for rehabilitation, at the same time as Mikoto and Stiyl destroy the other two.
As the Endymion terminates, Accelerator leaves and carries away Last Order in his arms as he jumps through the air. Last Order comments on how she is flying, to which an annoyed Accelerator says he won't be doing this for Last Order ever again.
Toaru Majutsu no Index-tanEdit
Accelerator reenacts his battle with Touma in the second episode of Toaru Majutsu no Index-tan. He reappears in the final scene of the special, reenacting the scene where he creates plasma. During that scene, he exaggerates his laugh and comments on how he no longer has a weak voice and is no longer an amateur as he won an award for his voice work (referring to his seiyuu). He later apparently kills Touma after an explosion which uses the dust explosion scene from the regular anime.
Toaru Kagaku no Railgun MMR: Much More RailgunEdit
He appears in the third episode. In one sketch, his seiyu takes over his role and complains to Misaka 9982 on how only the Toaru Majutsu no Index franchise gives him a long-running series role, much to her and the other seiyu's chagrin as despite the fact that he has little roles in anime that are not long-running, he instead get many roles instead in short late night anime. In the next sketch, Accelerator humors Mikoto in her complaints on girls like her liking childish things, to which he concludes that girls who are into those things are fine, but not with her, prompting her to charge towards him.
Video game appearancesEdit
Dengeki Gakuen RPG: Cross of VenusEdit
Accelerator appears in the game as a boss character; here he is already in his weakened state and using his cane, which allows the players to hit him. He is however, still powerful, able to use Redirection at certain times and uses Plasma Storm as his primary attack. He can also move very fast to close in on a character player. He also has a one-hit knockout move, where he touches the players and using his vector abilities to knock them out.
Toaru Majutsu no Index (PSP game)Edit
- Main article:Toaru Majutsu no Index (PSP game)
Accelerator appears as a playable character in the game. One notable aspect of his appearance is that he has already incurred brain damage and has to use the Misaka Network to do his calculations, though he retains his black shirt with white stripes and lacks his cane (as he tosses it away in his battle intro, making it seem that his powers are a bit more intact similar to pre-Toaru Index II)
LunatiaEditThe Accelerator is one the NPC characters that will assist the player in the Japanese version of the Korean MMORPG Lunatia. 
- Main article:Accelerator (ability)
Accelerator is named after his ability. It creates a thin field of AIM around him, which allows him to modify the vector values of anything he touches. After the events of Volume 5, his brain has been damaged, and he has to rely on a choker-style electrode that connects him to the Misaka network. The brainwave network allows him to use language, as well as making up for his lost ability to make calculations, although it is stated that it's less than half of what he once had. Furthermore the network enables Accelerator to reflect ultraviolet rays even when he isn't in esper mode. When using the network in esper mode, the battery of the electrode initially only lasts fifteen minutes. That changes in when he joins GROUP and its technical team cranks his time up to thirty minutes. He does not need the Misaka Network to use his abilities when in an awakened state.
He is shown to be far stronger than any other Level 5 in Academy City, being able to easily defeat the #2 Level 5 esper Kakine Teitoku without the use of his black wings. It should be noted that this fight took place after Accelerator's brain was damaged and he was forced to start relying on the Misaka Network to do his calculations, which reduced him to having less than half of his former calculation abilities. Accelerator has stated that as long as he has experienced it, he can analyze forces unknown to him as long as his body has been in contact with it, by following the vectors that have been applied (almost similar to a vaccine shot's case). He used this ability to understand Aiwass' "inexplicable laws."
He can change the vector values of anything by touch; for example, he kills a Sister clone by reversing the flow of blood inside her body after putting his finger inside her wound. Furthermore, this ability is automatic, so projectiles like bullets or explosives have no effect on him, as they will be redirected, even if he is unaware of their presence. He must consciously allow things like gravity and light to affect him. It is because of his ability that he has an albino appearance, as his "reflection" blocks all unnecessary ultraviolet radiation, thereby preventing the skin from manufacturing melanin. However, if one can find their way "around" his redirection ability (as demonstrated by Touma and Kihara Amata), it is shown to be rather useless, marking Accelerator as a Glass Cannon due to having a strong ability but a somewhat weak body (Touma/Kihara managed to bring him down to his feet in only around 7-10 blows).
He gains black wings towards the end of volume 13 when he had a epiphany right before he was nearly killed by Kihara, and fully awakened in his fight with the other level 5, Kakine Teitoku in Volume 15, during which he displayed a massive difference in power between them. When he Awakens, Accelerator usually loses almost all conscious control of himself and begins to speak in the language of the Angels. He gains the ability to understand laws that are hitherto unknown and unexplainable to him, and no longer needs to be touching vectors to control them. When under tremendous emotional pressure like in extreme rage, he manifests massive black wings, stated to be made of the same "Dark Matter" that the #2 Level 5 Kakine Teitoku creates with his ability. These wings do all the vector-related calculations for him, implied to be a much faster rate than his original calculating abilities- perhaps infinitely so, and as a result he does not need the Misaka Network to manipulate vectors. In volume 22, due to his pillar of support being changed by an epiphany after being defeated by Touma again, he manifests white wings and a halo and is able to block a massive amount of Telesma that Fiamma of the Right launched from the Star of Bethlehem. The Angelic nature of his ability is described as "The One Who Wields the Power of God" (「神にも等しい力の片鱗を振るう者」 Kami nimo hitoshii chikara no henrin wo furuu mono?).
Accelerator has demonstrated the ability to use magic, making him a Spellcaster. In volume 22, he used his vector ability to interpret the song used by Index to save Last Order and repeated the breathing method, casting the spell. As this was a pure magic spell, he suffered serious harm but saved Last Order. This is a possible factor that lead to Accelerator gaining White Wings, replacing his Black ones. After an explanation on the theory of magic provided by Leivinia Birdway, Accelerator displays his extreme delicate control over magic to having a side effect of using magic as unnaturally sweating rather than rupture of blood vessels and organ damage. An example of this is even when he has only a rough idea what feng shui was he is able to use a limited magic detection and then combine it with his knowledge of group psychology to make it become accurate. 
- Machine Ingenuity: Accelerator is also quite competent with machinery and technology, evident in when he modified his cane with various gravity sensors, and small motors to help better support himself.
- Marksmanship: After his fight with Kihara Amata, Accelerator realizes that he can no longer depend on his ability all the time. As such, he gets training with firearms and is shown to be extremely proficient in their use. Using his left, weaker hand, he was able to finish off a round of practice in 70 seconds. He has commented that reloading a pistol in two seconds with just one hand and his teeth is too slow, even though he was just testing the guns.
- Modified crutch: It is the crutch Accelerator always uses to support his body when he his esper ability is off. It contains a small motor and weight distribution sensors, allowing for it to determine the center of gravity. Instead of a single leg like a regular crutch, it ends with four legs attached to its end like a microphone stand, which according to the narration "holds the ground" helping Accelerator to get him up when he is down. The staff along with the four legs can be retracted in and out of the cuff. But its more imortant feature is a component inserted by Accelerator that blocks other interference devices. The crutch allows for Accelerator to block specific wavelengths after successfully analyzing it and using the equipment of the crutch, an interference wavelength can be reverse- engineered to specifically block that wavelength.
After the Level Six Shift experiment ended, Last Order approached Accelerator to ask him for help. Although reluctant at first Accelerator eventually decided to protect Last Order with his life. It has been stated that Accelerator is a parental figure for Last Order, and their interactions are like that of father and daughter. Near the end of World War III Accelerator admitted that he always wanted to be with her.
After defeating Worst in volume 20 Accelerator asks her for her help to protect Last Order, and after the war she moves into Yomikawa's apartment with him and Last Order. Accelerator views Worst as mostly a nuisance, finding her very annoying. Despite this he does not hesitate to rely on her for help whenever they are in a dangerous situation.
During the Level Six Shift experiments, Accelerator was openly cruel and sadistic towards the Sister Clones. He constantly berated every Sister with taunts before and during their battles as well as formulating brutal and horrifying methods against them. However, Last Order theorizes that his actions were intended to scare the Misaka Sisters and demoralize them from continuing the experiments thus implying that he never wanted to hurt them, but Accelerator dismisses her theory.
After his reform, Accelerator expresses remorse for the atrocities that he has committed and devotes himself to protecting the lives of the Sisters. The guilt on his conscience was substantial to the point where Accelerator was pushed to an emotional breakdown in his confrontation with Misaka Worst, stating that he would never bring pain or fear to the Sisters again.
After Touma defeated him, ending the Level Six Shift Experiment, Accelerator hated Touma with passion. Just the sight of him was enough to send him into rage, such as when he saw him in the events of SS1. He also subconsciously admired him and he was jealous of his heroic personality. Aiwass says that Accelerator is "chasing after" Kamijou and he wants to be like him. After World War III, Accelerator has calmed down about Touma and befriended him, fighting alongside him in the Hawaii Invasion Arc and trusting him enough to lend his powers to his ideas. During the Agitate Halation Arc, Accelerator even goes as far as to say to Touma: "Do you know what you need to do?" and when Touma replied: "Yes." Accelerator declared: "Then go. I’m not the protagonist here." Touma replies: "These ‘heroes’ are being controlled by a project called Agitate Halation. Be careful." Accelerator finishes the conversation by saying: Who do you think you’re talking to?" Here, it appears as if Accelerator has already managed to become confident in regards to his strength in relation to Touma's. However, Accelerator also acknowledges that he will never be quite like Touma and therefore lets Touma take the spotlight.
After he saved Last Order and was completely crippled, the researcher Yoshikawa Kikyou have gaved both of them (Last Order and Accelerator) to Aiho, they live now wiht her as freeloaders, it is stated that she is one of the few people which Acclerator sees as his family, in Vol. 15 he gained his Black Wings because Kakine have hurt her badly and was about to kill her, after his fight in Russia he, Last Order and Misaka Worst are living now together by her with Yoshikawa, one of the few examples of their close relationship could be seen in NT 1, where she punched Accelerator after he came back from WW3 and hugged him tightly direct after the punch.
Character Art DesignsEdit
Accelerator's character design is perhaps the most colorful of all characters in the series, though not because of revisions on his basic design but due to the changes the character goes through in the course of the novels. Haimura designed Accelerator during the course of his designing of the characters for volume 2; due to an editor's mistake, the plot of Volume 3 was sent to him along with the full text of Volume 2. Much to his surprise, Accelerator's basic design was approved. As volume 3 rolled into the corner, Accelerator's design began to be improved to fit his villainous role in volume 3. His design is based off Eric Draven from The Crow, the Joker from the Dark Knight, as well as a mouse. Accelerator's shirt is based off a face in Devilman and in Berserk (most likely the Hellhound).
For his redesign as the fledgeling protagonist, Haimura had Accelerator with a tokusatsu theme, specifically, Ultraman. His coloration is the most obvious change, from black and white originally to gray and white. According to Haimura, the design of his shirt is supposed to be something like a simplified representation of a bird of prey soaring from the sky after its prey.
For his winter appearance, Haimura uses an old design back from volume 16, in which he imagines what Accelerator would like with a winter outfit on. The general design remains but is further finalized in his second draft for Accelerator's winter design. Going for an gray alien appearance, Haimura had Accelerator's jacket made up of reflective materials and lamé. Here, Haimura designs a tentative pattern for his new undershirt that would appear in later volumes, but would be hidden for the arc it was designed for. Later, the shirt was redesigned a little for the 3rd New Testament volume, Accelerator's hair became even longer, and he gained new python pants.
- Accelerator noticed after initiating a dust explosion in his fight with Touma that the temporary lack of oxygen almost killed him. Because of this he realizes that even if he took on a direct blast from a nuclear weapon, he would then die from the lack of oxygen it caused. But in the novel, he subjects the idea that he could use an oxygen tank to remedy that situation, as some are made the size of hairspray bottles.
- Accelerator is the first known character who has managed to fill Index's stomach. Even when Maika cooks for Index, she only manages to fill 1/3 of Index's stomach according to Motoharu.
- Although Tree Diagram predicted that in a fight between him and Misaka Mikoto, she would die in 185 moves, the version of the SISTERS Arc in the Railgun manga shows that she would have been killed just by reflecting her strongest move, the Railgun, in 3 moves. Of course, this prediction is probably based on Accelerator's tendency to play with his opponents.
- His voice actor, Okamoto Nobuhiko, won twice in the Annual Seiyuu awards for his role as Accelerator. He first won Best Male Rookie in 2008 for his role in Index, and he also won Best Supporting Actor in 2010 for Index II. These achievements were both pointed out in the Index-tan specials.
- When spoilers on Volume 20 was first released, there was the misconception that Accelerator had somehow managed split the country Russia into two halves. Later this is found to be false, stemming from a mistranslation in the narration at the part where Accelerator has just defeated Misaka Worst.
- He is shown to enjoy coffee as there are instances in the light novel of him buying / wanting to buy coffee. He enjoys the same brand of coffee that Touma likes (black coffee without sugar), and at least once (Volume 5 light novel, before encountering Last Order and after his defeat from Touma) he actually bought every coffee can left in the store, "foiling" Touma's attempt to buy coffee the next day (another possible joking nod to Touma's "misfortune") .
- Due to his unusual introduction to Last Order and his equally unusual reaction to seeing her naked, not to mention their close relationship and the way he attracted Index's attention in Volume 12-13, fans have been joking that Accelerator might secretly be a lolicon. Misaka Worst lampshades this in New Testament Volume 1, because Accelerator is looking to help Fremea Seivelun.
- Main article:Accelerator/Quotes
- (To Imouto 10032 in Vol 3)"I strive for something beyond the strongest, that challenging me would be the most ridiculous thought ever, that fighting me would be a sin!"
- (To Last Order in Vol 5)"People have done this much to you. Sorry for taking so long...to save you".
- (To Amai Ao in Vol 5)"That's right, I killed over 10,000 of the Sisters, but this doesn't mean that I should just leave the remaining 10,000 to die. I know that these words are hypocritical, I know that I have no right to say such words, but no matter how much of scum bags we are, no matter how many excuses we put forward, those can't be the reasons to kill this brat!!!"
- (To Musujime Awaki in Vol 8)"You’re really pitiful. Listen, I’ll tell you one thing. That day, my brain was damaged alright. Looking at me now, you should know, right? That I can only use the electrodes and let the calculation work be done by others, right? If I enter a place where I can’t receive the clones’ electrowaves, I can’t let the clones do the calculation work for me. And even after therapy, I can’t even get half of my power. The battery of this thing can only allow me to fight for 15 minutes——But then again, just because I’ve gotten weaker, it doesn’t mean that you got stronger, RIGHT?"
- (To Musujime Awaki in Vol 8)“I'M SORRY, FROM HERE ON OUT, THE PATH IS ONLY A "ONE-WAY ROAD"!! YOU CAN'T ADVANCE, JUST HIDE BEHIND YOUR TAIL AND CRY YOUR WAY HOME!”
- (To Yomikawa Aiho in Vol 12) "It's impossible for me to show anyone good will. It's futile. What good is it to pay back a single yen on a one hundred million yen debt? I have no intention of paying out any good will if it will be crushed under nothing but the interest. It's ridiculous to even think about a joyous day when I've finished paying back it all. It gives me chills"
- (To the maintenance crew member in Vol 14) "They may all look the same to you, but there are different kinds and different levels of evil. A first-class villain doesn't target honest lives."
- (In Vol 14, referring to Academy City's troops) "Someone needs to tell those assholes there's such a thing as too much force. Using a blade for severing continents on a flesh-and-blood human is just wrong. I mean, how am I supposed to confirm the remains? Well, since the riots stopped after the blast, I guess the objective was carried out."
- (To Tsuchimikado Motoharu in Vol 15, referring to Last Order) "What's with that brat showing up in a situation like this!? That 'God' bastard sure is messing around!"
- (To Kakine Teitoku in Vol. 15) "Fine, now is a good time to teach you something: even Villains have standards!"
- (When asked who he is in Vol.19) “A Villain that’s no better than a piece of shit.”
- (To child in Vol.19) "I’m the Strongest Level 5, I don’t need brats worrying about me. Listen, even if someone is suffering before you, the kind of person that can take up arms without hesitation to shoot down the villain is no better than a villain himself. The kind that doesn’t care about others, doesn’t give 2nd chances; someone that kills is given a reason, is definitely not a hero. You don’t have to become that kind of person. That’s my specialty. Only I have to go through that"
- (Vol. 20) “You god damn fucking pieces of shit!! You rotten fuckers look down on me thinking my powers can only be used to kill!! I’ll show you right now!! Just like when I saved that brat from Amai’s virus back then, I’ll show you that I have the power to proteeeeeeeeeeeeeeeeeeeeeeecccccccccccccccccccccccccccccctttttttttttttttttttttttttttttt!!”
- (To Touma in Vol. 20) “It’s ridiculous that a villain who was no better than a piece of shit like me was guarding her!! No matter how you think about it something must have been wrong!! How could I possibly be a hero!! No matter what, I can only choose the blood-stained path!! Why do I have to do all these things!! If a hero like you had shown up earlier, then something like this mix-up of position wouldn’t have happened!! That brat would not had to have suffered as much this way!!!!!!!!!!!!!!!!”
- (Vol. 21, talking about Last Order chapter 8) "AAH!~ Fuck, I admit it! I want to protect her! I don't want to lose her!! I don't even want to think about the possibility of losing her!! I will face anything in order to protect this dream of mine!!!!"
- (To Last Order in Vol. 22) "I wanted to be with you forever, too."
- (Vol. 22) "I get it... this is what it means to fight to protect."
- (Vol. 22) "This is not a negotiation, a suggestion, a deal, an entreaty, an agreement, a compromise, or a capitulation. It’s my triumphant return, you fuckers."
- (NT: Vol. 1) "It’s true I have no real reason to protect her, but that’s no reason to just let her die."
- ( To Fräulein Kreutune, from NT6): "Fly"
- (To Mugino Shizuri, about the Dark Matter Sisters, from NT6): "I know…I know that. I know I’m just licking my own wounds. I know they only look like the real thing because I’m superimposing my own wounds over them. But even so…That is…They are the final proof that those I killed ever existed. No matter how horrible a method they are being used for, they are still the final evidence that the lives I stole were ever here!!"
- (To the "heroes" he is fighting, from NT7): "Interesting. Then let’s put you to the test, heroes. I’ll use these bloody hands to see if you are worthy of that name!!"
