The Accelerator (一方通行 (アクセラレータ) Ippō Tsūkō (Akuserarēta)?, lit. "One-Way Road") is the name used to refer to the 1st-ranked Level 5, the strongest esper currently residing in Academy City.

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 male protagonist of the Science Side after being defeated by Kamijou Touma. His journey to a more "heroic" role in the story progresses after meeting and saving Last Order and is forced into an ironic twist of fate where his life now depends on the Sisters, clones he previously killed by the thousands. He is also a major antagonistic character in Toaru Kagaku no Railgun and the protagonist of Toaru Kagaku no Accelerator.

In his role as a protagonist, he is forced to deal with the cruel Dark Side of Academy City and the secret conspiracies surrounding it. 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 teen 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 reduces the outside influence so much that it causes a loss of balance in his hormones, giving him what he calls an "androgynous appearance,"[2] although there is definite evidence stated throughout the series that he is a boy.

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 sometime between Old Testament Volume 5 and Old Testament Volume 8. 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 crutch after Old Testament Volume 5.

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 only believes in power and trusts no one. He also became a jolly and mocking yet maniacal person. 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 esper so that no one would dare to be foolish enough to challenge him and won't hesitate to kill anyone who gets 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.[3]

After meeting Last Order, he strives to protect 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.[4] 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. In spite of this, he does so in a violent way. In volume 15 he styles himself as the perfect villain in contrast to Touma being the ideal hero. However, despite his words, there is no mention in the narration that he has killed anyone and goes out of his way to incapacitate only his enemies up until his battle with Kakine, who challenges his contradictory way of thinking. This contrast with Touma is 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 Canceller, 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 Aiho's side. Deep down, he is someone that aches for the light, as shown when Yomikawa Aiho was able to walk up to him and slowly take a gun from his hands before he tried to finish off Kakine Teitoku after their fight,[5] and later when he refused to hurt a Misaka Worst clone and tried to heal her wounds after she tried to kill herself.[6] His obsession with heroes and villains is excised after his defeat in his second fight with Kamijou Touma, telling him to reject the confines of heroes and villains and just do whatever he needs to protect those he cares for.

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.[7]

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.[8]

In Volume 22’s afterword 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 Volume 22, Misaka Worst said half-jokingly she wants the same fatherly treatment he gives to the other Misaka clones.[9]


Young Accelerator

A young Accelerator.

Much of Accelerator's past is unknown, but he mentioned 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, yet his name had no real meaning in it.[10]

Ever since taking the Power Curriculum Program, and realizing his powers, Accelerator was sent to a "special class", most likely, the Special Ability Institute,[11] and spent much of his childhood there until nine years old, 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.[12]

When Accelerator was a child, he couldn't fit in with the other children due to his powers, harming those that tried to get close to him. Around at the age of 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.[10] 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 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 prior to joining the Level 6 Shift Project.

Accelerator's ability made him the subject of an experiment attempting to create the first Level 6 esper; 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 esper 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 that 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.

Sisters Arc

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, using 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.

Touma vs Accelerator

Touma defeats Accelerator.

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 Arc

LAst Order and Accelerator

Last Order with Accelerator.

After his defeat, Accelerator notices that something has changed within him as evidenced 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 had been severely vandalized 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 6 Shift Project. 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 by her lecture, Accelerator leaves Last Order in the restaurant although he shows some concern for 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 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 Ao abducts her. However, Accelerator easily locates and incapacitates 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 Ao, who shoots Accelerator in the head. Despite Ao'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 Canceller 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 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 Arc

Main article: Tree Diagram Remnant Arc

Accelerator about to deliver the finishing blow to Awaki.

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 him 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 Arc

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 Kikyou. 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.
Toaru Majutsu no Index II E19 15m 40s

Accelerator is initially no match for Amata's reverse punch method.

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 Amata 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 Canceller 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 Amata, crush the Hound Dogs and save Last Order, but decides to just focus on saving Last Order after a jarring conversation with Heaven Canceller, 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 Amata 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.

Toaru Majutsu no Index II E21 13m 20s

Touma talks to Accelerator about Last Order's whereabouts.

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 Amata, who now has Last Order captive, and breaks into one of Academy City Board of Directors' homes, digging up Amata's (and Last Order's) whereabouts. He attacks Amata's compound, but runs out of battery charge without being able to bring him down, yet ultimately kills him as he first "awakens,"[13] 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.

Index v14 291

Itsuwa defends herself from the monster within the scorching hell, Accelerator.

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.[14]

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. However, he didn't notice Touma and/or as they are covered by the steam. Accelerator leaves soon after to a deeper part of the palace. Itsuwa says she finds Accelerator, who is able to stand in the middle of such flames, to be even more terrifying than Terra.[15]

Battle Royale Arc

Main article: Battle Royale Arc

It is unknown how many days Accelerator spent in Avignon for his mission there, though when he returned he was immediately pulled into a mission for GROUP. Before doing so, Accelerator apparently realized the need to acquire the designs for his Calculation assistance device. After Last Order leaves in a taxi after being released from the hospital, the Heaven Canceller goes to a vending machine to get some coffee, to which a gun is immediately pointed to the back of his head by Accelerator, newly arrived from Avignon. He demands from him the designs of the electrode as he is the inventor. He asks why he needs it and asks him why he isn't he letting him fix it if it’s not working, though Accelerator does not tell. Heaven Canceller carries the conversation and tells Accelerator that Last Order wanted to see him, to which Accelerator says it has nothing to do with him. However, Heaven Canceller rebuts this, saying that she was his patient who wanted to see him and arranging that is his job, leading to Accelerator to complain. The doctor takes out from his coat a USB stick and hands it to Accelerator, making him note of his preparedness, leading to the doctor say that is his job to prepare for his patients like Accelerator. As he waits for his cup to fill with coffee from the machine, he tells Accelerator that it'd be difficult to apply its contents as he created the important parts himself, and says that of if he wants to make an identical electrode he needs to manufacture those using machine tools. Accelerator hears but doesn't answer, taking the USB with him and silently departed. The doctor then turns around and finds Accelerator gone as his coffee has been prepared.[16] After the higher-ups have manipulated to have the Anti-Skill swarm in on Family Side, Tsuchimikado Motoharu and Musujime Awaki are in the Family Side fifteen minutes after the explosion. While Awaki is disappointed with the destruction of evidence, Accelerator appears before them. Motoharu asks if he has finished with his errand, though he tells him to shut up. Accelerator then asks if this was the spot where Unabara Mitsuki (Etzali) disappeared to. Motoharu confirms it and tells them that Management is currently being transported for interrogation, though he doubts he can get much from it, as such he sent Etzali to Management's apartment for data but mentions that the third floor was attacked and that the appliances have been taken away, something that Etzali mentioned in his report to him before the explosion. Awaki however points out that not all have been taken away, and shows a microwave oven blackened by the explosion, believing that it was probably not loaded with AI and as such cannot be inputted with additional information. As Accelerator whines about their situation, he kicks on the microwave oven only to discover stacks of money inside it. Awaki notes that the bills have anti-counterfeiting IC chips and that they may get some information from them, and that Etzali protected them from radio signals by using the microwave oven. Accelerator wonders if Etzali hid them and advance. Then Motoharu notices a man stuffed inside a closet and sees that the skin by the right calf leg was torn off, disturbing Awaki. Motoharu then explains the "magic" behind it, but summarizes that Unabara Mitsuki (Etzali) has the skill to substitute as other people. Motoharu says to them that Mitsuki is still alive, masquerading as one of those who attacked the apartment and he has no idea where he is.[17] Putting the investigation on Etzali's disappearance on hold and having his fate in his own hands, GROUP continues with their original mission. They later receive word that the paddy wagon that held Management was attacked by an unknown assailant, with only him as a casualty and everyone else knocked unconscious. In their hideout in an empty store at the underground shopping center, GROUP tries to examine the paper money. Using the reader Motoharu had asked from their supplier, the machine starts analyzing. He discovers Management's shopping list, dealing with a single sniper as well a special sniper rifle, Sunazara Chimitsu and his MSR-001. Motoharu relates to them the specifications of the rifle as he continues to swipe the stacks of money for more information. By the fourth one, they find out that IC chips have been damaged, likely from heat or shock of the explosion, the stack having information regarding the business partner that hired the sniper. Giving up, Motoharu swiped the last pile of bills and discovers that they are the plans for the sniping, including the location of the sniping, the School District 7 concert hall. Motoharu notes that the plaza is being chartered for an address by Oyafune Monaka, one of the Board of Directors, and that she may be the target for assassination. He says that if that they should forget MItsuki (Etzali) to prioritize the assassination, and that the lowest "score" in the job will have to go and save him. Accelerator then whines about stopping the assassination, asking why they couldn't just stop the address. Motoharu of course gives the perfect response to this: the address has already started.[18] Motoharu and Accelerator quickly left their hideout using Awaki's Move Point, tiring her out. With Awaki preoccupied with analyzing the rest of the IC chips, Motoharu and Accelerator have to deal with the assassination attempt about to take place. Arriving at the address, they find Monaka completely exposed in the open with only a few security guards around her. Accelerator begins whining again, and then asks why Motoharu goes out of his way to protecting her despite being a member of the Board of Directors. Motoharu then discuss to Accelerator the difference between Monaka and the other Board of Directors, whom Accelerator believes to be all scum, hence the reason Motoharu is willing to protecting her. Motoharu somehow convinces Accelerator with his argument.[19]

Index v15 049

Accelerator and Motoharu noticing the inoperativity of the Wind Defense.

The two then try to determine the strengths and weaknesses of Monaka's security, noting of its Wind Defense technology set-up against sniper attacks. Suddenly, the both of them overhear Last Order talking to someone, actually Uiharu Kazari, saying that she is looking for a "lost child", and somehow managing to end up in the plaza. This irritates Accelerator, but amuses Motoharu. However, he himself becomes serious after seeing a young girl in a maid outfit mixing among the crowd, likely Tsuchimikado Maika, realizing that there may be stray bullets. Then they realize that some of the Wind Defense deployed in the plaza aren't working, shocking Motoharu. Then they actually hear the devices being hit by Sunazara Chimitsu's bullets, scrambled into action. Motoharu tried to get closer to Monaka to relay the danger to her but was unable to do so due to the crowd. With all the Wind Defenses gone, Accelerator was forced into action.[20] Before Chimitsu could shoot Monaka, an explosion at the corner of the concert hall front plaza was deliberately triggered by Accelerator, destroying one of the vehicles carrying a Wind Defense device. The surprise was enough for Chimitsu to miss his mark. He tries to shoot again but Monaka's bodyguards have already surrounded her and took her downstage. He shoots at his moving target but only struck one of the guards, who was knocked down but not killed because of his bulletproof equipment. Now knowing of a sniper the guards completely surrounded Monaka, hiding her behind them.[21]

By the time Motoharu arrived at the hotel room Chimitsu has already left. He later calls Accelerator to report on that fact, but states to him that Chimitsu continuing his sniping is low. Motoharu then tells Accelerator to have Monaka's speech suspended and have it transferred after security measures are set up again. Accelerator then reports to Motoharu on how Musujime Awaki have finished analyzing the IC chips in Management's stacks of cash and tells him that SCHOOL is behind the assassination attempt.[22] It was lunch time as they are in a camper van being driven by one of their grunts. After a few banters between each of them regarding their food choices, Accelerator asks if they have something on SCHOOL. Motoharu says that he tried accessing the Bank but discovered nothing came up other than their name, concluding that they likely have the same secrecy with GROUP. Awaki cuts in, saying that she tried to dig in as well, saying that multiple organization names like SCHOOL and GROUP came out as well, and surprising Motoharu. Awaki summarizes what she knows: GROUP, SCHOOL, ITEM, MEMBER, and BLOCK, all unofficial units created by putting a few people together. Accelerator listens on the conversation between Motoharu and Awaki where they could not confirm that it was SCHOOL that attacked Management's apartment.[23]

The members of GROUP had finished eating their lunches separately and were now discussing their plan for the upcoming investigation, but they were immediately cut off as they receive word that the Virus Isolation Center is being hacked. Accelerator whines on how they shouldn't be the one to deal with it as there are other organizations like them, but Motoharu says that they have different duties so there is no guarantee that the organizations would act, moreover, he says that the others may have betrayed Academy City. Realizing that the hacking may be used to spread a virus from Academy City to the Internet, the External Connection Terminals have all been shut down to prevent leakage, except one, the west terminal in School District 13. Motoharu references that whoever is doing the attack may be luring them to the district. As the driver takes to them to the district, he asks them about the deal with Oyafune Monaka, where he is informed that they'll deal with it later. When asked about saving Unabara Mitsuki, he is informed that they never intended in saving him.[24]

As they head towards the district, they are informed by the driver that there is currently an hacking on a satellite control center belonging to an aerospace engineering laboratory in School District 23. Accelerator frowns at the news as it means the hacker is targeting the Hikoboshi II, a satellite with a large caliber ground-attack laser. Awaki is uneased by the news as well, as the cracking on the Virus Isolation Center is still going. Motoharu points out that they are splitting up the counter-measure team and they just can't ignore one or the other as they don't know which one is a decoy or not. Reaching an empasse, Accelerator says that the answer is obvious. He gets out of the RV while it is moving, already using his powers, to which Motoharu yells at him. Accelerator explains to him that he doesn't like dealing with decoys and that he's going to School District 23 to stop the hacking by destroying the antenna used to contact the satellite. He then tells them to do the odd jobs without him. Accelerator then jumps on a car, pointing a gun to its driver, saying that he'll pay him gas and labor, ordering him to go School District 23.[25]

While in the car, Accelerator attempts to contact Anti-Skill to ask information about the satellite that is under electronic attack but the "Man on the Phone" who usually gives instructions to GROUP interrupted so Accelerator asked him instead. Accelerator asks for information about the Hikoboshi II laser, including its range. Getting all that he need from him, Accelerator hangs up. However, as soon as he does, he gets a call from Etzali. He tells Accelerator that he is currently in disguise. Accelerator assumes that he is hiding behind SCHOOL's back and says that he is busy dealing with the satellite hacking as such he can't answer his plea for rescue. Etzali clears to him that he is not with SCHOOL but with BLOCK and that they're the one who is doing the hacking. Accelerator references SCHOOL's attempted assassination with Oyafune Monaka, which surprises Etzali as he had no idea it had happened. Etzali continues with his report and says that BLOCK is the one behind the attack of teh Virus Isolation Center and one of the External Connection Terminals, doing so in order to confuse the City's network counter-measure team. Etzali says that the Hikoboshi II will fall into the hands of BLOCK in 20 minutes. Accelerator asks why School District 23 hasn't temporarily frozen the satellite control center, to which Etzali believes that the freezing it takes over an hour. Accelerator then asks Hikoboshi II, to which Etzali then concludes that they are using the laser to strike a target—School District 13, specifically the kindergartens and elementary schools. Both of them knew that attacking a district where children resided would be disastrous to Academy City, a city of schools that needs children to operate. Accelerator asks Etzali if he could stop them from where he is, to which he said he wouldn't have called. He then asks if he can evacuate the residents of School District 13, but says that it would cause panic and unfeasible as the children are outside due to the holiday. Accelerator insults Etzali for his uselessness and whines on how he has no choice but to destroy the antenna that communicates with the satellite. Etzaki agrees and says that he will continue to gather information and pass it to him when he can. Etzali then hangs up. Accelerator then tells the driver to hurry up.[26] The convertible Accelerator was riding in stopped near the terminal station in School District 23. After handing some money to the driver, he decides to use his powers to get to the antenna as it was still far away. However, he is then attacked from behind by Saraku before Accelerator can use his choker. Accelerator is injured but manages to get the upper hand and shoots behind is back, injuring Saraku, though without Accelerator's knowing, he manages to mess with the sight. When Accelerator turns to look at his attacker, he saw that Saraku is injured. Accelerator asks if he is from BLOCK, to which Saraku says that he is from MEMBER and that he is there to stop him from destroying the antenna. Accelerator then turns on his choker, activating his powers. As he turns around, he discovers that Saraku is already behind a railroad worker, and uses him as a hostage, using a saw to his neck. Accelerator gives a laugh, discovering the true nature of his power, that he cannot manage true teleportation's calculations and uses the positioning of other people to calculate where he can teleport. Accelerator mocks him, prompting Saraku to say that he doesn't want to hear that from him who uses a choker. Saraku says that Accelerator won't abandon the hostage as evidenced by the fact that he wouldn't have come to School District 23 in the first place to stop the Hikoboshi II. Accelerator, having now dubbed him as Kill Point, says to Saraku that he has no aesthetics of a villain and points his gun on him. Saraku however reminds Accelerator that there might be something wrong with the sights of his gun. Realizing that he might hit the hostage instead of Saraku, Accelerator did the next best thing, he shot himself in the temple and using powers, calculated and redirected the trajectory of the bullet. This method easily fells Saraku, making him bleed on the shoulder. Accelerator then motions the railroad worker to leave. Saraku continued to face Accelerator, though tried to look around using only his eyes to find someone to teleport behind. Seeing this, Accelerator mocks him as Saraku's is consumed by fear. Accelerator then says that he will now teach him of the aesthetics he lacked and what a true first-class villain really is. Accelerator then shoots at him several times enough to incapacitate him.[27]

Accelerator later arrives and faces against the Anti-Skill, defeating them all without killing them, and then destroys the antenna.[28] According to the Professor, Saraku apparently survived as Accelerator didn't kill him, and advises Yoshio Baba to retrieve him if he has the time.[29]

After the massacre near the outer wall, Motoharu and Awaki later joins up with Etzali and Accelerator. After Motoharu explains to them on how they destroyed the center of the western External Connection Terminal, Awaki asks Etzali a question if BLOCK was behind everything despite SCHOOL behind the assassination attempt of Oyafune Monaka. Etzali answers that they probably have their own plan as they caused separate incidents and that they just happen to have a point of contact with Management. Accelerator references MEMBER as well. GROUP then moves on to the area near the outer wall where the massacre happened and comes upon a survivor of the onslaught of the Six Wings. Motoharu demands answers from the man on what they were going to attack using 5,000 mercenaries. After some hesitation, the man says that they were planning on attacking School District 10, specifically the Reformatory. Hearing this, Awaki demands to know why as her comrades are being kept in the facility as well. The man tells her that they were after Move Point. Hearing her ability name being mentioned shocks her. The man says that they had information that Move Point's companions are being held in the Reformatory, and that if they capture her comrades they can negotiate with her. As she asks herself why they had to single her out, the mercenary reveals that it is because she is the guide to Aleister Crowley's Windowless Building. He says that BLOCK acquired information that the guide is Move Point despite the identity of the guide being confidential and had her investigated in order to find materials to use in a negotiation. Motoharu asks him what they were going to negotiate with the guide about, to which he says they wanted information on the route through which materials are brought into the building as so they can blow it up using a Synchronous Multilayer Bomb. The mercenary says that the chaos in the world needs to be stopped before War comes. The man continues by saying that negotiating with Move Point would be difficult, and that they worked under the assumption that she wouldn't help them. Awaki agrees, and asks if he knows who he is talking to. Horror dawns upon the man as he realizes this, before he could utter his surprise Awaki finishes cuts off, driving metal stakes all over his body, though it seemed he was still alive. Motoharu urges the others to go to School District 10 to stop BLOCK.[30]

Traveling in an ambulance to School District 10, GROUP discusses the layout of the Reformatory, discovering that there are secret rooms for the likes of Awaki's comrades, as well as its esper countermeasures such as the AIM Jammer. Motoharu warns that they can use their powers in spite of the AIM Jammer but says that it is possible to have their powers go out of control, especially those that use complex calculations, making it dangerous for the likes of Accelerator and Awaki.[31]

When GROUP arrives at the Reformatory, they notice that eerie lacked of gunfire. As the pass through the gate and came to a traffic circle for vehicles that shuttered prisoners around, Accelerator notices the slightly painful effects of the AIM Jammer. Luckily however, it doesn't hinder his walking, though he notes he should avoid switching over to esper mode. His thoughts on the devices used in the facility against esper facilities is cut off after they find the strange state of corpses of BLOCK mercenaries. Motoharu comments on how they all lost their lives to their own weapons, to which Etzali asks if it was suicide. However, he realizes something, but before he could speak of it there was a voice behind them. It is Xochitl, who calls out to Etzali who was in the guise of Unabara Mitsuki. Seeing this, Accelerator thinks she's from BLOCK, but she says that she is from MEMBER, though she just used them and had no intention of joining them. Etzali reacts to Xochitl, asking for who she is, to which Xochitl responds and says his real name. Etzali was shocked and then Xochitl finally removed her disguise. Xochitl states that she needs to thank BLOCK on account of the esper powers being halved in the Reformatory as so she doesn't need to worry with his companions getting in the way. Etzali then asks why she's there, telling her that she's not supposed to have a spell that can do what she did (regarding the mercenaries getting killed by their own weapons). Etzali says that Xochitl was supposed to be in a position in their cabal that kept her away from any dirty work. She tells her reasons and that is to kill him as he had defected to Academy City. Hearing of this Tsuchimikado Motoharu realizes Etzali's situation. Etzali tells the rest of GROUP that he will deal with Xochitl while they go on ahead. He then tells to them her name is Xochitl, an Aztec magician who also belonged to the organization he was in before coming to Academy City. Xochitl then says that she only came for Etzali and doesn't care if they go off. However, she then says on how she wonders if "they" will let them. At that moment gunshots are heard, prompting Accelerator and Motoharu to take cover. Motoharu discovers that BLOCK's mercenaries were waiting to see what would happen between them, and asks Xochitl if they really have to deal with them but she just ignores him.[32]

After Etzali later successfully takes ownership of the grimoire that took over Xochitl's body, he meets up with the rest of GROUP, all of whom were not unscathed.[33]

Due to BLOCK's collapse things have settled down. Motoharu was taking care of wrapping things up, Awaki was taking care of her wounds, and Etzali was safe and likely took Xochitl to a hospital.[34] Meanwhile, Accelerator went back to School District 7. He later receives a call from the GROUP liaison, though as usual he doesn't receive him well. He thanks Accelerator and GROUP for his efforts against BLOCK, saying that he is fortunate to have such capable subordinates. This however annoys Accelerator. The liaison points out however that he is thanking him from the bottom of his heart, and to prove it, gives him useful information related to Last Order's life.[35]

Accelerator finds Kakine Teitoku torturing Uiharu Kazari for information to where Last Order's whereabouts where. After Uiharu defies Kakine, Accelerator throws a ATM vending machine at Kakine. Despite Accelerator's attack, it barely made a reaction on Kakine, saying that he was hurt. He however, says that he was irritated and that it was only right for him to come and kill him first. Accelerator mocks him however for talking and then taking a hostage (Uiharu Kazari). Kakine replies that Uiharu was only a little insurance as no one would fight Accelerator fairly. Kakine then mocks him for believing that protecting weaklings made him out as a good guy. Accelerator however states that Kakine still doesn't understand, and that he will show him on how even villains have standards. With that the two of them clashed in the city. Kakine is knocked back by this and then smashed into a cafe. Despite this, Kakine is fine and comes out of the cafe. He notes Accelerator's power of controlling any vector and asks him what would happen if he was smash into a large mass that can't be moved regardless of all the vectors he can gather, though says that it would likely not work. He tells him that as long as his vectors aren't being controlled it is meaningless. Not only is Kakine unhurt, he was apparently enveloped by six wings like that of an angel's. Now spread behind him, Accelerator mocks him for being unoriginal, though Kakine says that he doesn't have to worry about it as he already knows.[36]

Index v15 299

Kakine battling Accelerator above Academy City.

And thus they do battle once more, and upon the air they meet. As Accelerator gets close, Kakine references the particles that make up the world, and then states that kind of knowledge doesn't apply to his Dark Matter, as it is is something that doesn't exist in the world. Despite the wings that defied the laws of physics, Accelerator's will is unshaken, and continues to come close, declaring that he will blast him and his Dark Matter as well. But Kakine says that Accelerator still doesn't understand, and then his wings projected out a light that hurt Accelerator, surprising him for he believed he could reflect all his vectors with his ability. Kakine says that it was the diffraction of sunlight through the unseen gaps of his Dark Matter wings, changing the light's nature and use it to attack him. Kakine asks him how it felt to be burned by sunlight. However, Accelerator calls Kakine a fool, saying that no matter how he diffracts sunlight, it doesn't change its nature into something like a beam of light that kills. Kakine says that would be the case for normal physics of the world, but not for his Dark Matter. With that boast, he blew a gust at wind at Accelerator, who tried to subdue the wind through the use of his reflection. As he pondered on what to do, he found Kakine smiling, saying that his reverse calculations are complete. Then, his wings struck and felled him in spite of his power. Kakine says that Accelerator is wrong that he can reflect everything as Accelerator tries to fly towards him, but his wings were ready to meet him. Kakine gives examples as he presses his advantage over Accelerator, injuring him. Here he says on how not everything is reflected by him, explaining to him that he has a subconscious filter that reflects anything that could harm him. He says that he using the energies that are infused by Dark Matter like the sunlight or the wind, he can choose which energy is the most suitable in bypassing his filter after he had analyzed it. This complicates things for Accelerator as even if changed the rules of his reflection, Kakine would merely inspect the change his Dark Matter and then continue his attack. Despite this they continued to clash. Accelerator made four tornadoes through his power, and wing by wing, Accelerator and Kakine's blew and swept each other apart. As they continued to attack each other, wreaking havoc upon their surroundings. Kakine mentions on how killing him, the #1, is the fastest method in accomplishing what he wants, which is to directly speak with Aleister himself. As they exchange blows, Kakine reasons that since Aleister has a web of plans up his sleeve, he needs to destroy all other plans, allowing him to the only viable plan left for him, the so-called "Spare Plan".[36]

The two of them stood face to face, gauging each other. Accelerator thinks that there must be some truth to what Kakine has said about Aleister having many plans, and wonders what tragedy has struck him in the Dark Side of Academy City that shaped him to what he is to push him to what he does. Accelerator however mocks what Kakine said, to which Kakine says that despite Accelerator having the right to directly communicate with Aleister he doesn't use it and that he has no right say that to him. He tells Kakine that that the moment he spoke those words of his, he became common filth passing themselves as a great villain. Kakine however is unconvinced, giving his explanation as to why, saying he doesn't want to touch normal people, and if he's in a good mood, he'd let bad guys live, though all in all he doesn't really care whether they live or die. He tells Accelerator that they are the same as in their battle he asks him how many bystanders got hurt by their attacks. Accelerator says that including the person (Uiharu Kazari) that shielded Last Order, they are all the same, and that Kakine, someone who kills bystanders has no right to lecture him, and that Kakine is not exempt from his own ideals. As Kakine doesn't believe this, Accelerator shows to him why he is #2 and he is #1, why there is an impassable wall between them. Here Kakine discovers, much to his disbelief, that despite the destruction caused by their battle, no bystander was hurt due to the efforts of Accelerator, everything was under his control from the beginning of the battle. Here Accelerator tells him that what he is what should be called a villain. Angered by Accelerator, Kakine increased the power of his six wings and prepared to do battle once more, confident that he has no way to defend himself as he knew about his filtering system, though Accelerator is unintimidated. Accelerator admits on how his Dark Matter can work against his reflection, to which he tells Kakine that all he needs to do is add Dark Matter into his calculations, using his ability to control Dark Matter. Kakine laughs at this prospect. After a couple of banters, the two clashed once again.[36]

Accelerator defeats Kakine Teitoku, taking control of his white wings and stabbing him with it. Though terribly injured, Kakine still lives. As Accelerator was not one of those "good guys" and since Kakine willingly involved civilians and Last Order, he prepares to execute the unconscious Kakine with this. Yomikawa Aiho appears before Accelerator and begs him to put down his gun and spare Kakine. Accelerator points a gun towards Aiho, as even though she was one of the "good guys" she impeded in what Accelerator believes to be his "path of evil". Accelerator hesitates, to which Aiho says that he can't do it, as he hasn't "rotted" that much. With Accelerator unable to fire, she slowly takes the gun from Accelerator's grasp and took away its ammunition. As Accelerator stared blankly after what had happened, he suddenly hears something: Kakine Teitoku has stabbed Aiho. Accelerator is in shock as Kakine restores his white wings and mocks Aiho's words to Accelerator. Afterwards Kakine rants on about the darkness and on how the both of them are still the same, unable to protect anybody, and will continue on killing. Kakine stands up and uses his powers to step upon Aiho. Accelerator begs to stop, but Kakine continues to torture Aiho, wanting him to push him to the edge, wanting him to be as low as him, mocking him for becoming soft. And thus, Kakine shatters the pillar that supported Accelerator.[5]

Accelerator's Black Wing

In anger, Accelerator's Black Wings come again.

Seeing the black wings, Kakine deemed to be made from Dark Matter. Impressed by its power, Kakine that Dark Matter is only suitable as a spare plan, though he says that it doesn't meant it's all decided. With that his wings spread out and glowed, Accelerator and Dark Matter, black wings and white wings, the organic and inorganic, the One Who Wields the Power of God and the One Who has Touched the Territory of God, face to face. Then an unprecedented power expanded within Kakine, perfectly mastered his power. Kakine laughs at the implications of what would happen now, as he waved his completely awakened six wings down at Accelerator. As he tries to test his new powers on Accelerator after seeing him as no longer a threat. Immediately after Kakine is splattered onto the asphalt and his right hand torn from the shoulder. Despite his injuries, Kakine is too shocked to take in what happened, believing he was untouchable and believing that Accelerator changing vectors and energies of some sort to redirect it towards him as an attack was impossible. Torn apart and unable to do anything, Accelerator walks toward Kakine and slaughters him.[5]

Accelerator continues to go on a rampage with his black wings, forcing Anti-Skill to respond. Luckily, Aiho was able to survive, and tries to stop Accelerator after she comes to. However, she is stopped by Saigou Ryouta, who tells a great distortion is taking place with regards to the AIM Diffusion Fields. She breaks from Ryouta's grasp, only to discover several armored Anti-Skills and armored vehicles. Aiho demands them to put their guns down, and tells that it is their duty to protect Accelerator. Aiho tries to come close to Accelerator, though because she is injured, blood spurts from her mouth, and is restrained by Ryouta. However, their last hope, Last Order, appears, coming out of the crowd at great speed towards Accelerator. As his black wings continued its rampage, Last Order approaches, and says that she has finally found him. However, Accelerator tries to attack, and though everyone flinches believing that Last Order has fallen to her demise, the black wings stop before Last Order. But Last Order is undeterred as it shows that Accelerator is still has control. An Anti-Skill opens fire without permission while Accelerator is distracted, responding to this his black wings try to attack, only for Last Order to plead him to stop, and he does. Last Order holds out her arms and says that all is all right now and there is no need to do what he is doing. As if to blow apart those words, the black wings try to again but once again stops before her, his conflicted heart consuming his action. He continues to scream in turmoil, and finally he roars and the sounds of the black wings wave once more. They try to attack the unperturbed Last Order, all of which miss its mark. And then it swelled up greater than it has ever been and tried to strike down Last Order again. It reached in front of Last Order, Accelerator's movements have stopped. With his head lowered, the black wings disappear and Accelerator falls, all of his strength leaving his body. Last Order catches Accelerator with arms wide open, and held him with all the strength she could muster. With that Last Order whispers to Accelerator's ear of her relief. Finally the lost child is found.[37]

After Accelerator's triumphant battle against Kakine, the liaison calls him to remind him of the gravity of his actions in the battle. He tells him that he was the one who gave him the information regarding Kakine in the first place and as such won't be too hard on him. Accelerator asks him what his penalty is, though the liaison wonders as both increasing his debt and killing him just is inappropriate, his tone irritating Accelerator. Then the liaison asks an unexpected question, asking him if he has not given up on coming back to the "warmth" after falling that far and declaring that he will stand at the very top of the darkness. Accelerator answers that he still hasn't and asks him if he is going to stop him. The liaison answers that he will give them right to struggle, though he cannot guarantee him that he has the right to grant him that. Accelerator, satisfied with his answer hangs up on him, swearing that he will outwit the darkness.[34]

At some unknown point in time later in an unknown location, Accelerator, Tsuchimikado Motoharu, Unabara Mitsuki (Etzali), and Musujime Awaki gathered together. Motoharu shows the Tweezers that he had recovered from the confusion after Accelerator's fight with Kakine, shocking him that he was hiding among the onlookers. Motoharu references on how SCHOOL was able to collect a nanodevice known as UNDER_LINE and store it inside the Tweezers in order to examine it. Accelerator becomes suspicious on how much Motoharu, and realizes that he may have been taking secret actions of his own. Motoharu shows to them the information inside the UNDER_LINE, the core of Aleister's direct communications network. Seeing that it was all a bunch of information they were able to get on their own, and that it was just information the higher-ups are gathering to keep an eye GROUP's actions, they become dismissive of it. However, Motoharu reveals that there is one more, and says the last one the list of information displayed on the Tweezers’ screen is the word DRAGON. After all that fighting, they made at least one little discovery, a key that they could potentially use.[34]


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, except for Accelerator, got knocked unconscious. Before losing consciousness as well due to blood lost, Shiokishi exclaimed the one behind them that did this wasn’t Fuse=KAZAKIRI like Accelerator thought after Etzali's comment about DRAGON could be used as a meaning for an "angel".

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 itself are manifested, Last Order is heavily strained and may die/collapse if left untreated. Accelerator finally got provoked and tries to strike down Aiwass, but he suddenly receives a heavy wound on his upper body when charging in. It turns out Crowley had embedded an auto defense into Aiwass's appearance to prevent suicide. Accelerator then lost completely to Aiwass even after unleashing his Black Wing. However, in the end he used his cane to block the Misaka Network, thus making Aiwass to be slowly disintegrated. He then pulled out his gun and shot the core in its head.[38] Unfortunately, Aiwass was unscathed and Accelerator laid on the floor bloody and unable to move. As he struggled, Aiwass praised his attempt, said that would have taken it out if it were on the same level as Fuse=KAZAKIRI. An angel's halo then appeared above its head and Aiwass said "It seems I can transform," before knocking Accelerator unconscious.[39]

Taking Last Order with him and hiding themselves in a freight train, Accelerator headed to Russia, specifically toward the Elizalina Alliance of Independent Nations, after Aiwass suggested not even Heaven Canceller could heal Last Order this time. Aiwass said him that he could find a completely different set of laws that he has never seen before there and to remember the term "Index Librorum Prohibitorum", because, though that itself was not actually there, important item dealing with it was. Accelerator crushed his cellphone, erasing his last link to Yomikawa Aiho, Yoshikawa Kikyou, GROUP and then began his search for a means to save Last Order in Russia.[7]

World War III Arc

Main article: World War III Arc
Index v20 037

Accelerator talking to Last Order.

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, and high-speed Powered 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 and 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 Elizalina'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 Elizalina'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 of the Right 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.

Index v22 216

Accelerator saying goodbye to a cured Last Order.

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.

Toaru Kagaku no Railgun

Sisters Arc

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 9982. 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 Kamijou 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 Arc

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

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.[40]

Toaru Kagaku no Accelerator

Accelerator is first seen reading a book while still recovering from his headshot that he received from Amai Ao until after the Disciplinary Action Anti-Skill member captured Estelle Rosenthal and left which is when he shut the book he was reading, sat up, and yawned before picking up a photo that was on the floor that was apparently dropped by one of the people that was involved in the incident mentioned that was of Last Order prior to clicking his tongue, grabbing his modern-cane styled crutch and throwing a paper on to a notebook that had its cover written on by Last Order previous to walking out of the hospital, confronting the DA member and saying to him to hold up and leave the luggage he has as in Estelle where she is because he had something to ask her.[41]

Main article: Toaru Majutsu no Index Movie: Miracle of Endymion
Accelerator movie

A snapshot of Accelerator's trailer debut, showing the scene of Accelerator arriving at the base 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.

Misaka misaka fly

Last Order comments that she is flying as she is carried by Accelerator away from Endymion.

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-tan

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 Railgun

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 seiyuu'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.

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 Majutsu no Index II’’).

Dengeki Gakuen RPG: Cross of Venus

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.

Dengeki Bunko Fighting Climax

Accelerator is one of the supports added to the game. His first assist makes Last Order appear, as she wanders confused into the stage. If an enemy attack hits her Accelerator will appear, blocking the attack and using his Dark Wings to swipe at the enemy. His second assist consist of Accelerator stomping the ground, creating a fissure that damages the opponent and causes them to bounce between the ground and the top of the screen a few times.


The Accelerator

Main article: Accelerator (ability)

Accelerator has to rely on a choker connected to the Misaka network.

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.[44] 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 rely 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, by following the vectors that have been applied, almost similarly to the immune system. He used this ability to understand Aiwass' "inexplicable laws."


Rather than creating a vector from nothing, Accelerator may instead alter the vector of an object that he touches. This aspect of his power is versatile offensively and defensively; not needing conscious control, Accelerator may deflect or redirect bullets that strike him, or the pressure wave of an explosion without requiring his awareness of the threat. Accelerator may apply this ability consciously however, to such effect as reversing the blood flow within someone's body by touching an open wound. Accelerator must consciously choose which vectors naturally interact with him-- including the vector forces acting on him from gravity or incident light. Because of this 'reflection' of light, unnessesary ultraviolet light is deflected by Accelerator, contributing to his albino appearance as his body ceases to produce melanin. The defensive power of this ability is impressive, but if negated or worked around through some other means, Accelerator himself is quite fragile and easily beaten down.

He acquires black wings towards the end of volume 13 when he has an epiphany before being nearly killed by Kihara Amata, and fully awakens in his fight against the #2 level 5, Kakine Teitoku in Volume 15, during which he displays a massive superiority in power. Whenever he awakens, Accelerator usually loses almost all 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 contact with vectors in order to control them. When under tremendous emotional pressure, he manifests massive black wings, stated to be made of the same "Dark Matter" that Kakine Teitoku creates with his ability. These wings do all the vector-related calculations for him, implied to be much faster than his original capabilities, and as a result he does not need the Misaka Network to manipulate vectors in this state. In volume 22, due to his pillar of support being changed after his second defeat by Touma, he manifests white wings and a halo and is able to block a massive amount of Telesma that Fiamma of the Right launches 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. 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.[45] 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.[46] 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 increase its accuracy.[46] However, Magic still presents a great foil to Accelerator, as when he was tricked into fulfilling the conditions to perform a spell by magician disguised as a Trident member he suffered from the rejection reaction without having taken steps to lower the damage beforehand, which caused the blood to burst from his right arm. The extreme pain involved lowered his calculation ability to a point where he was unable to use his Reflection ability, leaving him helpless.[47]

Other abilities

  1. High-level Intellect: Accelerator has shown frequently to possess a very high intellect. For starters, his esper ability is shown to require complex calculations to function, with him being skilled enough in this field to come up with a new application on the fly during his battle against Touma. He also appears to have a very good memory, as he memorized the codes for Last Order's default mind state and was able to remotely return her to that condition, thus erasing the virus planted into her by Amai Ao. Later, he also starts to display clever strategies in battle, as when he was able to take out the Hound Dogs using firearms, which he utilized for the first time against them, along with exploiting his immediate environment and his enemies' psychological state to his advantage, without using his esper ability. Even with less than half of his calculation ability, it is great enough to allow Accelerator to calculate and analyze all the 25,000 different kinds of energy of Kakine Teitoku's Dark Matter, while fighting on par with him and protecting bystanders. Finally, he was able to figure out a way to block the signal used to shut off his electrode and to figure out ways to diminish the harmful influence magic has on his body as an esper, which is a feat only one other individual has accomplished so far. He is also fairly skilled at identifying spies; as well as being a skilled interrogator, as he was seen to easily break a Russian spy with Misaka Worst's help.
  2. Machine Ingenuity: Accelerator is also quite competent with machinery and technology, evident in when he modifies his cane with various gravity sensors and small motors to help better support himself. He also implants in it a mechanism to overcome the Board of Directors and their subordinates' means to shut off his choker-style electrode by memorizing the wavelength they use and blocking that wavelength afterwards.
  3. Marksmanship: After his fight with Kihara Amata, Accelerator realizes that he can't consistently rely on his power. As such, he trains with firearms and is shown to be extremely proficient in their usage. With his left, weaker hand, he is able to finish off a round of practice in 70 seconds. He commented that his reloading of a pistol in two seconds with just one hand and his teeth is too slow, even though he was simply testing the gun.
  4. Driving skill: Accelerator displays enough skill to drive a motorbike, seemingly without issues.[48]


  • Choker-style electrode: After he was shot by in the head, Accelerator, despite having survived, had his frontal lobe badly damaged and lost his ability to walk or use his motor skills, as well as his verbal and calculation abilities, preventing him from properly reading and speaking. This unique electrode, which is attached in his head, connects him with the Misaka Network and thanks to the limited connection to the brainwave network he has gained enough calculation ability to think normally, understand and speak, walk, etc. The choker has three modes: off, normal mode, and esper mode, where the battery runs out in 15 minutes after entering this mode. This was later modified to 30 minutes, but it was also tampered with at the same time with a safety device that allows for someone to remotely prevent the device from switching to esper mode.
  • Modified crutch: The crutch Accelerator always uses to support his body when he is in normal mode contains a small motor and weight distribution sensors that allows it to determine Accelerator's center of gravity. Instead of ending a single leg like a regular crutch, it ends with four legs attached to the end like a microphone stand, which, according to the narration, "holds the ground" helping Accelerator to get up when he is down. The staff along with the four legs can be retracted in and out of the cuff. However, its more important 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 in the crutch, generate an interfering wavelength specifically engineered to block the original wavelength.


Last Order

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, as he wants to protect his family.

Misaka Worst

After defeating Worst in volume 20, Accelerator asks her for her help to protect Last Order, and after the war she moves into Yomikawa Aiho'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.

The Sisters

"It’ll be all right. If you need something to prove you existed, I will be that remnant. I will dig deeply into this world to leave behind an indelible mark that will prove that you were here as the ones who were sacrificed to the monster that I am. These twisted records are no longer needed. I just have to return you to a place where the dark side of science like me can’t reach you. I will end it all!!"
―Accelerator's conviction before facing Kakine Teitoku[src]

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 enough to push him to an emotional breakdown in his confrontation with Misaka Worst, stating that he would never bring pain or fear upon the Sisters again.

The Will of the Whole Misaka Network states that the difference between him and Touma is that he views The Sisters as the epitome of good while Touma views them as normal humans.

Kamijou Touma

After Touma defeated him, ending the Level Six Shift Experiment, Accelerator hated Touma with a passion. Just the sight of him was enough to send him into rage, such as when he saw him during the events of SS1. He also subconsciously admired him and was jealous of his heroic personality. Aiwass says that Accelerator is "chasing after" Touma and wants to be like him. After World War III, Accelerator has calmed down about Touma and befriended him, fighting alongside him in the invasion of Hawaii and trusting him enough to lend his powers to his ideas. During the Agitate Halation Project, 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.

During NT10 it is shown that Accelerator now cares about Touma to the point that he lost to him on purpose so that Academy City and the other level 5 espers won't come after him, since defeating the strongest one of them would mean that it would be impossible for the weaker level fives to win.

Hamazura Shiage

Because he killed the first leader of Skill Out, Komaba Ritoku, Hamazura Shiage was originally hostile to Accelerator. When he was escaping with Takitsubo Rikou, which was when Accelerator first met Shiage face to face, Shiage had mistakenly thought that Aleister Crowley had sent Accelerator to kill him. Because of this, Shiage attacked Accelerator but failed to defeat him, and the fight ended after Accelerator was able to clear up the misunderstanding. After World War III, both Hamazura Shiage and Accelerator returned to Academy City and later worked together to save Fremea Seivelun. When both had met Kamijou Touma, the two were introduced to the magic side of the world and were told of the existence of GREMLIN.

Yomikawa Aiho

After he saved Last Order and was crippled, the researcher Yoshikawa Kikyou took both Last Order and Accelerator to Aiho, where they lived with her as freeloaders. It is stated that she is one of the few people which Accelerator sees as his family. In Vol. 15 he used his Black Wings to protect her because Kakine had hurt her badly and was about to kill her. After his fight in Russia he, Last Order and Misaka Worst are living now together 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 directly after.

Character Art Designs

Design evolution

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 Kiyotaka 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, and the change of colors symbolize his change in personality after meeting Last Order.

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.
    • The Seiyuu also later play the same type role as Karma Akabane which was thought to be strongest of all but later defeated by main protagonist, Nagisa on a duel at Assassination Classroom.
  • 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.[49]
  • The character Add from the Korean MMORPG Elsword bears a striking resemblance to Accelerator. Although looking similar to Add, KoG confirmed that they had no intention of giving Add a same personality as Accelerator, confirming the only thing similar between the two is the voice actor.
  • One other possible trait that Add shares with Accelerator aside from his appearance and slightly close psychopathic personality is that one of his jobs/paths/classes are called Diabolic Esper, which is a reference to the Toaru world involving espers.
