List of Toaru Majutsu no Index characters

This is a list of characters from the light novel series Toaru Majutsu no Index as well as its manga adaptation, spin-off manga (Toaru Kagaku no Railgun), and both series' anime adaptations. The series primarily takes place in Academy City, a city filled with students who strive to become powerful espers, which is brought into conflict by the appearance of magicians.

Tōma Kamijō

 * Tōma Kamijō (上条 当麻) is the series' main protagonist. His power is Imagine Breaker (幻想殺し), a power which negates all magic, psychic, or divine powers but also his own good luck ("divine providence" as defined by Index). Because this ability can not be detected through testing, he has been given the lowest psychic rank, Level 0. Due to the nature of his power, the founder of Academy City considers him neither a Psychic nor a Magician but rather a normal person with a unique ability.

Due to the nature of his power, the founder of Academy City considers him neither a Psychic nor a Magician but rather a normal person with a unique ability.


 * He tends to stay away from trouble but possesses a strong sense of justice, albeit somewhat shallow and dogmatic. He is a smart student and knowledgeable about certain subjects yet is a failure in his esper studies. While he is an idealist for the hopes of other people, ironically he is cynical about himself possibly because of his powers.


 * In order to save Index from the need of a memory reset, he had activated her self-protection system and destroyed the spell responsible for her mind strain. However, he ends up having his memories destroyed when he comes into contact with the Feather of Light (光の羽). Though he no longer remembers the past, he claims his heart has not completely forgotten the people he cares about. His memories loss is kept a secret known only to himself and a few others, including his doctor (who unknown to Tōma, is Heaven Canceler, Aleister's personal physician), his parents (after telling them the truth during the Academy City Sports Festival), Terra of the Left (who manages to figure it out by himself), Mikoto (who learns about it from accidentally overhearing a conversation between Tōma and Terra, confronts Tōma about it), and, recently, Fiamma of the Right (who, after learning about it, decides to toy with Tōma by sending this information to Index using the mental link he established with her using Johann's Pen mode).


 * Throughout the series, he tries to live his life normally while still facing against the many adversaries from the worlds of science and magic and the conflicts that follow. Despite his very bad luck, he has managed to get the interests and hearts of many ladies who are infatuated with him, which Aisa jokes about, that his life is like a dating sim where he is bound to unlock more paths to more girls.


 * One of the series' main mysteries is the origin of Imagine Breaker, since it is neither an esper ability or a magical ability. Later in the series, it is hinted to be of Divine origin according to two members of God's Right Seat. Fiamma believes Imagine Breaker is the Holy Stone, which holds the power of miracles and Terra hints Imagine Breaker's full powers have yet to be unlock; if it does, its powers would extend to Tōma's whole body and beyond.


 * Due to the troubles he faces with delinquents, Tōma is a skilled street fighter and is physically fit and manages to out run his opponents. As he faces espers and magicians, he combined his fighting skills including using his powers with his quick thinking to out maneuver his opponents. It is later revealed that he has something approaching a sense for incoming magic and esper attacks based on their AIM fields and Telesma flow and uses his powers to minimize the damage taken.

Index

 * Index (インデックス), also known by her full name Index Librorum Prohibitorum, is one of the main heroines and the titular character of the series. She is a young nun from Necessarius (必要悪の教会), a branch of the Church of England. Index is small in stature and has a petite build. It can be assumed that she is very young. She has thigh-length, silvery-blue hair, and large green eyes.. She also wears a white robe, the Walking Church, that prevents any injury on her, but it is later destroyed by Tōma when he touched it with his powers, which is why her uniform is stitched with golden pins. Her mind has been implanted with the 103,000 magical texts of the Index-Librorum-Prohibitorum as she possesses Photographic memory, which makes magicians wonder if she really is human because just one grimoire is poisonous to the mind, and one is more than enough to kill a person without the proper preparative.

 * Her sorcery name is Dedicatus545, "The lamb is devoted to protecting the wisdom of the strongest". The Church says that the grimoires take up 85% of her mind, so she only has 15% of memory space left to use in daily activities, which allows her to live normally for less than a year. However, all of this is revealed to be a lie after Tōma begins to question how the Church even got to numbers like 15% and 85% and finds out from Komoe that the human mind can store an unlimited amount of memories. This was purposely done as the Church planned to make the grimoires harder to access by telling their underlings to perform "maintenance" on her mind in exactly one-year intervals once her memory has come to its "limit"; that way, she will not remember her close friends and accidentally and/or purposely reveal the contents of the grimoires.


 * When she is being invaded by outsiders or injured, her self-protection system personality, Johann's Pen mode, will be activated to allow her to use magic. Her self-protection system will use the Feather of Light (光の羽) to force a reset on Index's own memory should a manual reset fail to be performed. Although she does not know that she has magical powers, she can easily identify the types of magic by seeing it or somebody describing it to her and know how to counter them.


 * She is often elated by a variety of things and is slightly ignorant and curious of modern technology. She usually is gentle and polite with people and has a kind nature, but she is also easily irritated especially by Tōma who usually ends making her mad in some way as consequence of his bad luck which ends with her biting him. She also has an extreme appetite and uses any excuse to get food from anyone and likes watching an anime series called Magical Powered Kanamin.


 * Her vast knowledge of the Index-Librorum-Prohibitorum within her mind becomes helpful to her friends in various situations using skills like "Spell Intercept" and "Hell Fear" and makes her a target of interest for many. She has strong feelings towards Tōma and even confessed her love after hearing Tōma lost his memories because of her, however he avoided answering by changing the theme of the talk because since he has no idea about what kind of feelings he used to have towards Index. When she returns to England, she is sought out by Fiamma who wants her knowledge and reactivates Johann's Pen mode. Later during her stay at Necessarius Headquarters at St. George Cathedral, learns the bitter truth about Touma from Fiamma, he was lying the whole time because he actually lost his memories, going on a rampage grows "Red Wings" and defeats Styil with ease who tries to restrain her just by flapping her wings.

Mikoto Misaka

 * Mikoto Misaka (御坂 美琴) is one of the series' main heroines, as well as the main protagonist of her side story, A Certain Scientific Railgun. A psychic user of Academy City, her powers are ranked Level 5, the highest rank for the most powerful psychic users, and she ranks as third-strongest out of the seven people who hold this rank in Academy City. Her power is to generate electricity; she is powerful enough to cause a blackout in the city, make instant railguns by firing coins (hence her nickname, Tokiwadai's Railgun), and use electromagnetism to manipulate iron particles around her into a chain-sword whip. She can also manipulate electronics such as computer networks and security systems.

She can also manipulate electronics such as computer networks and security systems.


 * Mikoto attends Tokiwadai Middle School, a famous girls' school for the rich and elite psychics and one of the five elite schools of Academy City. To most people, she is considered a proper lady, but in reality, she has a short-tempered, prideful, and improper attitude with some tomboyish tendencies and insecurities, a fact few other characters know. She is fond of cute, childish things, such as flowery pajamas and Gekota, the popular frog mascot franchise. Contrary to what she claims, she has a strong sense of morals and hates injustice.  Mikoto has a one-sided rivalry with Tōma, who nicknamed her "Biri Biri" (ビリビリ), ever since their first meeting before the events of the first novel when he first dissipated her electricity. Since that incident, she is always trying to have a proper match with Tōma and defeat him despite his many attempts to avoid conflict with her.


 * When Mikoto was young, she was tricked into giving the city's scientist her DNA under the pretense of finding the cure for Duchenne muscular dystrophy; their actual goal to create military-grade combat clones of her. When it was discovered that the clones didn't have the same power level as Mikoto, they were instead used in an Project called " Level 6 Shift", intended to make Accelerator the first level 6 esper by having him kill 20,000 clones. The events of how Mikoto tried to stop the project are briefly mention in the third novel, and expanded and given more detail in the Toaru Kagaku no Railgun manga. When all of her attempts failed, she contemplates letting herself be killed by Accelerator, in order to prove the Tree Diagram's calculations faulty. However, it is not until Tōma intervenes and beats Accelerator, proving him to be really weak, that the project is cancelled and the remaining 9969 surviving Sisters are spared.


 * After the events of the third novel, she eventually develops strong feelings towards Tōma but is unable to express them due to her insecurities and the fact other girls were also interested in him. Even though she and Tōma tend to bicker and argue with each other, they share a somewhat friendly relationship. Both of them have gone on a date (albeit one that was a result of a bet between the two) and exchange cell phone numbers. During the events of the 14th novel, she calls Tōma, who is on a trip to Avignon, France when he is attacked by Terra of the Left. Even though his cellphone is damaged, Mikoto is still able to listen and is shocked to hear from Terra that Tōma actually lost his memories and has been hiding this fact from his friends all this time. Confused, she confronts Tōma when he returns to Academy City in the 16th novel. After that, Mikoto overcomes her initial confusion regarding her concern for him and realizes she loves Tōma. She reappears in volume 20, when upon learning Russia might launch missiles against Academy City and seeing Tōma in a live TV report at Russia, Mikoto heads to Russia after hijacking a jet from the Academy City Invasion Force ordered to find and capture Tōma. After arriving in Russia, she and Misaka 10777 heads towards a nuclear military base to stop the missiles from launching.

Accelerator

 * Accelerator (一方通行) is the most powerful Psychic in Academy City. His real name is unknown, though Accelerator recalls his surname was composed of two characters and his given name consisted of three characters. First appearing as an antagonist of the third light novel, he later becomes a main character and the lead of the science side in the Toaru Majutsu no Index series in a notable number of volumes of the light novels. Because Accelerator has been this reflexively powerful since childhood, he was unstoppable even when the military was sent to kill him. However, these past influences resulted in his inability to trust others and he was left alone. After meeting Tōma, he develops a sense of admiration and jealousy towards Tōma's heroism and ability to help others, contrasting with how Accelerator feels he is only able to destroy.

 * A sadistic boy about the same age as Tōma, he has an ability called "Redirection", a form of telekinesis allowing him to change the vector values of anything he touches. This ability allows Accelerator perform feats such as reversing the blood flow inside a person's body, increasing the wind velocity around him to create a massive plasma storm, and blocking sound.  His ability is automatic, which means that he must consciously allow gravity to affect him and that his body blocks all ultraviolet radiation, resulting his albino appearance (white hair and pale skin) because his body is unable to make melanin.  The automatic nature of Redirection also prevents the use of projectiles (like bullets) and explosives (like bombs) against him.  After being shot by Ao Amai, Accelerator's ability to use his power is hindered, but slowly recovers with the help of Heaven Canceler and the Misaka Network.  However, he is forced to use a cane and is restricted to using his ability for only 15 minutes at a time, as well as losing more than half of his computation ability even with 10,000 sisters doing calculations for him. This time frame was extended later in the light novels.  In the 15th novel his power become more powerful after his powers 'awaken,' allowing him to manipulate vectors without the need of the Misaka Network.  The wings are expression of his AIM field and Aleister Crowley comments that the process of Accelerator's awakening is "the process of downloading the data of the AIM field, unto the vector controlling device has finally been completed". It implies that turning Accelerator into an Artificial Angel has been Crowley`s plan all along, and goes hand in hand with creating a Level 6.  During Accelerator's fight against Russian mages and streamlined-highspeed power suits in Russia, it is disclosed his powers are able to affect teleportation and is able to partially affect magic.


 * Accelerator's unique ability make him the subject of an experiment attempting to create the first Level 6 psychic; according to the city's best supercomputer, Tree Diagram (which was unprecedentedly destroyed by Index's Dragon Breath), this feat could only be achieved by killing 128 skilled Level 5 psychics without a single failure. Since there are only six other known Level 5s in Academy City, an alternative plan was formed to "level up" Accelerator by having him kill 20,000 skilled Level 2 psychics: the Misaka clones. He willingly joins the experiment to gain a reputation as the most powerful and feared psychic that no one would be foolish enough to challenge and even killed many who got in his way. The Sisters' memories of his behavior during the experiment may suggest that he is, in a way, a pacifist; since his power won't disappear, the only way he sees to stop fighting is to be so strong and sadistic that no one would raise a finger against him. He even seems to attempt to frighten the Sisters or otherwise encourage them to refuse the battle. Mikoto tries to stop the experiment to save her sisters, but it is Tōma who finally does so and defeats Accelerator after discovering his weakness: Accelerator was physically weak because of his total reliance on his powers. Overconfidence in his psychic abilities resulted in his defeat as Tōma beat him with his Imagine Breaker and street-fighting skills.


 * After his defeat in volume three of the light novels, he reappears in volume 5 and takes a more heroic role protecting a girl named Last Order, the last Misaka clone. In the aftermath of the incident, Accelerator is shot in the head by Ao Amai, damaging his brain and severely limiting the use of his power. Toward the end of volume 13, Accelerator begins to "awaken" after nearly being killed by Amata Kihara and truly "awakens" in volume 15, gaining Black Wings, when fighting another "awakened" level 5, Teitoku Kakine. In the events of the 19th novel he meets Aiwass, a higher dimensional being, summoned to their plane of existence. Aiwass explains to him when AIM entities like him are manifested, Last Order is heavily strained and may die if left untreated. To help Last Order, who has collapsed from sustaining Aiwass, Accelerator follows Aiwass advice and heads to Russia during World War III in search of Index, unaware that he has met her before.


 * In Russia, after being ambushed by Russian mages he acquires the "Kremlin Report", a mysterious military document sought after by both, Academy City and the Russian government that may turn the tide of the war and later runs into a Misaka WORST clone and learns that Aleister intends to eliminate Last Order, now obsolete, and create a new Misaka network. Despite being more powerful than the Misaka WORST clone, Accelerator is unable to bring himself to harm another clone after the Level 6 experiment and becomes mentally unstable after the clone attempts to kill Last Order and then tries to kills herself. Accelerator goes on a rampage until Tōma arrives; Accelerator turns his frustration regarding Last Order's condition onto Tōma and a fight ensues between the two. After Accelerator is defeated again, Tōma uses his Imagine Breaker to stabilize Last Order and leaves a note informing him of Index's true whereabouts. Later he join forces with Elizarinian soldiers to find spies in their country and fought Archangel Gabriel along with Hyōka.

High schoolers

 * Motoharu Tsuchimikado (土御門 元春)
 * A blonde teenager who is always seen with sunglasses and wearing an Aloha shirt. He is a friend and classmate of Tōma who just happens to be his next-door neighbor at the dormitory they're staying at. While he seem like a normal, average teenager, there's more to him than meets the eye. Secretly, Tsuchimikado is actually a former agent of Necessarius who became a freelance spy for Necessarius, Academy City, and other unknown organizations; the leaders of both Necessarius and Academy City are both aware of this but have decided to let him be for the time being. His sorcery name is Fallere825, 'the back-stabber'.

He is also a member of one of Academy City's secret organizations, the "GROUP". His ESP ability is the Level 0 Auto Regeneration (肉体再生). Due to this power, he can still use magic as he can repair the damage done to his body, making him the only successful psychic/magician hybrid. Despite these advantages, he avoids using magic except in the most desperate situations as he cannot avoid the extreme pain caused by using it.


 * Blue hair and piercings (青髪ピアス)
 * Tōma's friend and classmate whose real name is unknown. A funny individual who tends to notice Tōma's bad luck, and has calls him "Kami-yan" in a different way.

Her abilities have yet to be revealed.


 * Mii Konori (固法 美偉)

In the past, she used to be a member of a Skill-Out gang called Big Spider to find a purpose in her life. It was there where she met and fell in love with Wataru Kurozuma, the leader of the Big Spider's. But after his supposed "death" two years ago, the incident made her change her ways and become the Judgment member she is now.

Nagatenjouki Academy
One of the top five most prestigious schools in Academy City, supposedly the number one. Unlike Tokiwadai, entry is not restricted to just espers but normal students with no powers are allowed admittance as well. It was also stated to have beaten Tokiwadai in last year's Daihaisai Festival.


 * Accelerator
 * He is affiliated to Nakatenjouki according to his documents. He moves to their dormitories after the events of volume 13.


 * Shinobu Nunotaba (布束 砥信)
 * Shinobu is a student from Nagatenjouki Academy, who worked on the Sisters' Radio Noise experiment before it was shut down. She was called again when the Sisters project was revived to be used for the Level 6 Shift program. However, when she noticed the Sisters clones had something of a conscience, she was unable to see them as objects anymore. She attempted to stop the experiments by using envelopes containing cash cards to lure in witnesses in the unwatched alleyways, where the Sisters would fight Accelerator. She does not appear to have any powers, but uses good acting to invoke fear into enemies and make them believe she has a deadly one. It is through her that Mikoto learns about the Sisters experiment. She later infiltrates one of the remaining facilities involved with the Sisters project with the hope of installing fear emotions into the Sisters in order to cast doubt and question the morality of the experiment among the scientists involved. However, she was captured by Saiai Kinuhata and her program was apprehended by Last Order before it could spread through the Misaka Network.

Tokiwadai Middle School
One of the elite five schools of Academy City, this elite girls middle school is located within District 7, the School Garden. As one of the most renowned girl schools in the world, all of the students come from rich backgrounds and are at least Level 3 espers, a requirement to enroll there. The school has the honor of having two of the level 5's studying there.


 * Mikoto Misaka


 * Kuroko Shirai (白井 黒子)
 * Mikoto's kōhai in Tokiwadai Middle School; a protagonist in Toaru Kagaku no Railgun and main character in the eighth volume of the Toaru Majutsu no Index light novels. A Level 4 psychic, she is a member of Judgment, a special public committee group whose duty is to maintain peace and order in Academy City. She has an obsessive crush on Mikoto, who she calls "Onee-sama" (big sister) and is on the constant lookout for a chance to get physically intimate with her (which is rarely appreciated). She tends to get jealous towards other people who get Mikoto's attention; which usually ends up being Tōma. Her powers are instant teleportation, which allows her to teleport herself and anything in her possession as long it weighs under around 130-137 kilograms to anywhere in a radius of around 81-85 meters. She generally carries a strap of nails around her leg that she can teleport to pin down enemies. Teleporting objects into other objects displaces them, allowing her to cut through hard objects like giant concrete pillars with just a sheet of glass. One disadvantage of her power is that she has to concentrate on where she, the object(s), and/or person she holds/touches would be teleported to, for any disturbance in her concentration will make her powers useless.

Kirigaoka Academy for Girls
One of the five elite schools of Academy City, this girls high school is unique as unlike other schools, only students with rare and unique powers are allowed to enrolled.


 * Aisa Himegami (姫神 秋沙)
 * A quiet young girl with a rather blunt personality who wears Miko attire. While she may seem normal, she is also known as "Deep Blood" and has the ability to kill vampires when they approach her, as her blood's smell attracts them. However, it made her miserable because it killed her family and friends that were turned into vampires. This prompts her to go to Academy City, hoping to find a way to get rid of her powers, until she meets the alchemist Aureolus Izzard. She cooperates with him because he told her that her blood can be used to save the life of a person he cared for (Index) in return for helping her get rid of her powers.

 * When Aureolus learns Index's life was already saved by Tōma and tries to kill him, Aisa attempts to defend Tōma, which prompts Aureolus to use his alchemy to try to kill her as she was now useless to him. Her life was saved by Tōma who dispelled the spell on her with his right hand. When she asks Tōma about why he saved her, he told her that he did not have a reason to rescue her. After the incident, she lives with Tōma and Index but later moves to Komoe's apartment and wears a magical power-blocking cross, which enables her to live what she had always wanted: a normal life. She initially attends Kirigaoka Academy, but transfers to Tōma's school when her sponsor, Aureolus Izzard, mysteriously disappears, thus ending her enrollment at Kirigaoka. Ever since Tōma saved her life, Aisa started to have feelings for him, which is ironic as she once joked that Tōma's life was like a dating sim.

Not much is known about her aside from the fact that she was an overachiever at Kirigaoka Academy for Girls (霧ヶ丘女学院), according to Aisa. Her ability is Counter Stop (正体不明). Details about her level are unknown but it could be high, since it was mentioned that she was among the top psychics in the Kirigaoka Academy for Girls. It is later revealed that she is not a human at all but instead an algorithm of the psychic's AIM with a conscious. The nature of her being leads her to be indestructible, as she can recreate any damage done to her body and lift objects several times her size. When not physically manifested, she exists in a realm called the Imaginary Number District which she calls 'the city of shimmers', a hidden dimension within the city. During the 12th novel, she returns but as "FUZE=Kazakiri", her artificial angel mode where she is summoned by the Academy City Board of Directors who forcefully control her to stop an attack by Vento of The Front.

Usually shy and humble, her personality will quickly change to overly excited especially if it concerns the life of the upper class especially anything involving Tokiwadai. She has a sweet tooth but is always called for Judgment duties before she can enjoy them. She displays various skills with the use of computers, such as repelling hackers and gathering information. In several omake manga chapters, it is joked that her ability is to control plants, but in the anime, it is finally revealed that her power involves keeping anything she touches at a constant temperature. Since she can't handle hot or cold things, she limits this ability to warm things.

 * Shiage Hamazura (浜面 仕上)
 * A former Skill-Out who was first introduced in the Side Story novels where he became the leader of his Skill-Out gang after Accelerator killed the former leader by orders of the Board of Directors. However, on the same day he became the new leader, his gang was hired to kill Mikoto's mother, Misuzu but were defeated by Tōma and Accelerator. Humiliated, he left the gang to his friend Hattori Hanzo and became a chauffeur and informant for Team ITEM where he fell in love with Rikou.


 * He plays an active role in the 15th, SS2, 19th, 20th and 21st novels. During the 15th novel, he betrays and fights ITEM's leader Shizuri Mugino to protect Rikou and defeats her using tactics and a gun. However, his actions interfere with Aleister's plans as he's an anomaly that goes against his plans, so Aleister sends his assassins to eliminate him. Ironically, he is saved by Mugino, who now has a sense of twisted love for him (declaring she will castrate him as her sign of affection) and helps him and Rikou escape Academy City by stealing a jet. After he and Rikou jump out of their jet, they end up in a warzone in Russia where he is forced to fight Academy City mercenaries along with some villagers until they are saved by Acqua of the Back. He and Rikou later heads to Elizarina hoping to find refuge there where Rikou is partially healed by Accelerator. He is seen fighting along with Elizarinian soldiers and aiding help to Acqua. He also heads towards a nuclear military base (the same Mikoto and Misaka 10777 are going as well) to protect the Kremlin Report before anything happens to it but is intercepted by Mugino.


 * Shiage has similar characteristics straits to both Tōma and Accelerator. Like most members of his Skill-Out gang, he is lawful. However, while he is very smart yet isn't as idealistic or as nice as Tōma and acts based on his own desires. In battle, he prefers to avoid fighting or to finish the fight as quickly as possible, which is a contrast to Accelerator's old personality. He is very embarrass on sex-related issues.

Academy City's Level 5s

 * Within Academy City, the Level 5s are the most powerful psychics in the city. The following are the currently known Level 5 users starting from the strongest.


 * 1) Accelerator
 * 2) Teitoku Kakine
 * 3) Mikoto Misaka
 * 4) Shizuri Mugino
 * 5) "The Queen of Tokiwadai"
 * 6) Not yet revealed.

However, his powers allow him create a strange explosion around him that throws people away, feel a prickly pain but will not receive serious damage when he is shot or pierced in the heart, perform physical combat with double the speed of sound, cover his whole body with an unknown forcefield and use a projectile-force which he calls "Amazing Punch." Due to a misunderstanding, he fights against a powerful magician named Aurrelus with the aid of nine Misaka Sister clones, but is still defeated.

Sisters

 * Introduced in the third story arc of the series, they are Mikoto Misaka's clones, which Tōma refers to as Misaka's little sister (御坂妹). Unlike Mikoto, they seems rather quiet and emotionless, their voice is rather monotonous and computer-like and they talk in third person by adding a description of themselves after they finish talking. Also they wear a special set of goggles that enables them to see electron beams and magnetic field lines for the reason that, unlike Mikoto, they don't have that ability.


 * Even though they have a weaker variant of Mikoto's electric abilities (Level 3), the Sisters' minds are connected by a special psychic ability called Radio Noise (欠陥電気), which enables their brainwaves to become electric signals; this allows them to share their thoughts and memories within their communication network, also known as the Misaka Network. Being rapidly-manufactured clones, the Sisters rarely change their facial expression because they did not learn how to. Due to minds having connected to the Misaka Network, most of the Sisters never considered themselves human yet some of them had slight difference in personalities.


 * Originally, the Sisters were created as efficient Level 5 combat clones for the Military under Project Radio Noise but the project was halted when the Sisters were revealed to be weaker and were only Level 2 and 3. The Sisters were later use in another project called "Level 6 Shift" where about 20,000 clones were created in total and were used to be killed by the participant who might become the first Level 6 psychic, Accelerator. By the time of third novel, 10,031 were killed in the experiment before is was finally stopped by Tōma and Mikoto. After the Level 6 Shift experiment fails, all 9969 surviving Sisters are ordered back to research centers around the world to have "readjustments" so that they will have normal life spans. The Sisters later began showing their owned unique personalities to differentiate themselves after learning how to 'disconnect' from the Network and keeping their own private memories inaccessible to the others in the Network.
 * The following Sisters had the most prominence in the series:


 * Misaka 10032 (ミサカ 10032)
 * Misaka 10032, also known as Misaka imōto, is the most prominent clone that is most featured in the series. She is known for having a soft spot for cats which she herself has a pet black kitten. She was the first sister clone that Tōma met. Due to the many interactions she had with him, 10032 wonder why she thought about him so much. Misaka 10032 was Accelerator's latest target in the Level 6 experiment, but Tōma manages to stop him. Confused, she asks why he did it since she was a clone, to which he replied that even though she was a clone, she was still an individual with a life. His words (along with Mikoto's) affect her so much that she and the Sisters decide to help Tōma against his fight with Accelerator.

 * After the Level 6 experiment was canceled, she was one of ten Sisters to stay in Academy City while the rest went overseas around the world for treatment. She later falls in love with Tōma and receives a heart necklace from him (so he won't mistake her for Mikoto) which she treasures.


 * Last Order (打ち止め)
 * Misaka clone No. 20001. She is the administrator of the Misaka Network and the fail-safe mechanism in case the Sisters got out of control. She is not designed to function independently and survive for long outside a culture container and appears to be only about ten years old. Due to intercepting an emotion program Shinobu Nunotaba intended to install into all of the clones, she is capable of showing emotions unlike the other sisters and has a close relationship with Mikoto, Misaka Imōto, Accelerator and her adult guardians, Aiho and Kikyō. Like her older clone sisters, she speaks in third person with a description, except she says "Misaka" twice. She has all of the memories of the Misaka clones and has observed Accelerator through this method, posing a theory that Accelerator did not actually want to do the Level 6 Shift experiment.

 * Accelerator meets Last Order when she follows him home one day after he fends off a bunch of street thugs hearing of his defeat against a Level 0. Though Accelerator tries to dissuade her from hanging around him, she persists in following him around because she wants someone to keep her company. She is later kidnapped by Ao Amai so he can infect the Misaka clones to possibly go on a rampage and attack people. Accelerator manages to stop him but gets injured in the process. Last Order and Accelerator are put under the care of Aiho after the incident. Accelerator does all he can to protect her since she is the first person in his life who requested his help. Throughout the story, she remains with Accelerator and has been involved in situations relating to him. After Accelerator's confrontation with Aiwass, she is left in critical condition. However, Accelerator brings Last Order with him to Russia in hopes of finding Index who may have the knowledge to cure her.


 * Misaka 9982 (ミサカ 9982)
 * Introduced in Toaru Kagaku no Railgun, she was the first Sister clone Mikoto met. While she was similar to the other clones, 9982 had a rather unique personalty, as she was very interested in the outside world. She was very snarky to people, often giving long detailed critiques on their taste in food. The one thing that she desired was to meet her older sister, Mikoto, the girl whom she was cloned from. Upon their first meeting, the two had an awful start due 9982's refusal to reveal to Mikoto what the Sisters were involved in, but they both later bonded somewhat after Mikoto gave her a Gekota badge.


 * Sadly, the meeting would be their last as 9982 was scheduled to fight Accelerator that day. Despite being horribly beaten, including having her leg ripped off, 9982 appreciated the time she spent with Mikoto in her last moments. She died, crushed by a passenger car thrown by Accelerator, still clutching the first and only gift she received from Mikoto.


 * Full-Tuning (０００００号)
 * Serial-number 00000 of "The Sisters" designed by Ao Amai. As her serial number suggests, she is a prototype clone and the "first" Sister clone. Her details and whereabouts are unknown.


 * Misaka Worst (ミサカワースト)
 * The Misaka Worst are a group of specially designed 2nd generation clones of Mikoto that appear in volume 20. Unlike the 1st generation Sister clones who were Level 2 and 3 espers and were design as combat units, these new clones are a higher Level 4 espers and were specially created for special operations; as such, they are well-equipped with battle gear, gliders, and combat masks. Their appearance is that of a slightly older Mikoto with a darker appearance and personality in contrast to the previous clones, which show little emotion. Academy City deploys one of them in their war against Russia, where she attempts to assassinate Last Order. Accelerator tries to stop her without killing her as he doesn't want to harm another Sister again. After finally subduing the Misaka Worst assassin, he tries to eliminate her programming to make her harmless but she almost kills herself to prevent that, sending Accelerator into an emotional breakdown. Later in volume 21 novel, she makes peace with Accelerator by assisting him.

Teachers

 * Komoe Tsukuyomi (月詠 小萌)
 * Despite her childish and very short (135 cm) appearance, she is actually an adult and one of Tōma's teachers; this is proven by her apartment being littered with beer cans and cigarettes. She also contradicts her age by acting childish to her students, having a child-like crush on Tōma, and ending her sentences with desu, something a child usually does; this irony means that she is often regarded as one of the seven great mysteries of Academy City. She has major interest in studying pyrokinesis and performs magic once, when Index requires her to participate in a magical ritual to heal her wounds, meaning she is one of the few non-psychics in Academy City. Her name is an aptronym as the character "小" means "small" and the character "萌" means "moe".

Not making things any better is the fact Aleister was responsible for the creation of the truce between Science and Magic where neither side is allowed to interfere in each other affairs which has irked both sides. As the General Superintendant of Academy City, Aleister has the final say of the city affairs but usually leaves the city's welfare to the 12 Directors of the board. He resides within a tall, gray building called The Windowless building, known for not having any exterior windows where access to the building is a secret to a few.

British organizations

Due the joint ruling between the three organizations, they have made Britain one of the most powerful magical organization in the world, rivaling the Catholic Church.

Necessarius
The secret magical branch of the Church of England. Officially name the "Church of Necessary Evil", the organization was started by Puritans who despise the use of magic in England and sought to destroy it by using magic themselves but now the organization no longer has an anti-magic stance and supports magic. Officially, Necessarius is under the authority of the Archbishop of Canterbury but the current leader and Archbishop of Necessarius secretly controls the Archbishop of Canterbury thus Necessarius is the true power behind the Anglican Church. As one of the three magic powers of Britain, Necessarius represent the religious magic community. Necessarius is currently lead by Archbishop Laura Stuart.


 * Stiyl Magnus (ステイル＝マグヌス)
 * A sorcerer from Necessarius. His sorcery name is Fortis931, "My name is the strongest proof, here is why". He is an extremely heavy smoker; he claims a world without nicotine would be hell. He specializes in using runes to invoke his power over fire. He is able to use a flame sword and summon a 3000-degree-Celsius fire elemental called Innocentius (魔女狩りの王) to battle his enemies. He is a man wearing a black robe and has long red hair, and a bar code tattooed on his cheek. Despite his looks, he is actually fourteen years old and is physically weak as casting Innocentius weakens him.

When he learns the Church lied to him and Kaori about Index's condition, he decides to disobey orders to capture Index and allow her to live her life. Despite the lies, he remains with Necessarius and becomes the assistant to the Archbishop of Necessarius herself.

 * Kaori Kanzaki (神裂 火織)
 * An eighteen-year-old sorceress from Necessarius. Unlike her partner Stiyl, she uses magic to magically strengthen her body. Her sorcery name is Salvare000, "The one being saved becomes the hand that saves". She uses a two-meter-long nodachi called "Seven Heavens Seven Swords" as her weapon. She has a special attack called Nanasen (七閃) that uses her sword and some wires.

After Tōma saves Index's life and her current memories, she decides to let Index stay at Academy City as she feels Tōma can protect her.

 * Later in the novels, more of her past is revealed. Not only is Kaori a skilled swordswoman, but she is a Catholic Saint possessing the "Stigma"- the ability to call upon God's power- and the former leader of the Amakusa Catholics; however, Kaori left the group as she resented that she had been fated since birth to become its leader, which led her to despise the concept of luck and fortune. Though she is Catholic, she joined Necessarius in hopes of changing her fate and befriended Index, developing a sisterly relationship with her. The repeated failed attempts to make Index remember her after each memory erasure resulted in her cold personality as Kaori began to accept that no matter how much a person tries, no one can change their destiny. She begins to show a kinder side to herself after Tōma saves Index (thus giving her hope that anyone can defy their destiny) and gradually falls in love with him after he helps her face her past with the Amakusa Catholics, becoming more prone to showing emotion and sometimes showing a little embarrassment if she is with him.

During her assault, she reveals to Tōma that she seeks to keep science and magic divided as revenge for her late friend Ellis, an esper from Academy City. Ellis was involved in a secret experiment 20 years ago between Academy City and a faction of Necessarius in an attempt to create the first magician-esper hybrid. But it failed as not only did the espers participants suffered major injuries from magic but were killed by the Knights of England as the experiment was illegal under the truce between Science and Magic. Blaming both sides for letting Ellis suffer and be killed, Sherry swore revenge against them by making them suffered like she did.
