- Tōma Kamijō (上条 当麻 Kamijō Tōma)
- Voiced by: Atsushi Abe (Japanese); Micah Solusod (English)
- Tōma is the main protagonist of A Certain Magical Index. He tends to stay away from trouble but possesses a strong sense of justice. He is an average 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.
- His right hand contains a power called Imagine Breaker (幻想殺し (イマジンブレイカー) Imajin Bureikā, "Illusion/Fantasy Killer"), an ability which negates all supernatural powers but also his own luck ("divine providence" as defined by Index). Because this ability cannot be detected through testing, he has been given the lowest esper rank, Level 0. Due to the nature of his power, the founder of Academy City considers him neither an esper nor a magician, but rather a normal person with a unique ability.
- 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 characters that are in love with him, which Aisa jokes about. The reason is not only to his personality, but he avoids the red thread of fate, according to Index.
- 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 Hikari no Hane). Though he no longer remembers the past, he claims his heart has not completely forgotten the people he cares about. His memory loss is kept a secret known only to himself and a few others, including his doctor Heaven Canceller (who unknown to Tōma is Aleister's personal physician), Terra of the Left (who manages to figure it out by himself), Mikoto (who learns about it from accidentally overhearing the conversation between Tōma and Terra), Fiamma of the Right (who, after learning about it, sends this information to Index using the mental link he established with her using John's Pen mode), Index (who finds out from Fiamma), Seria Kumokawa (who realizes it since Tōma isn't "talking" to her the way he should know), and finally is Misaki Shokuhō (who figures it out when Tōma doesn't recognized the nickname she calls him).
- One of the series' main mysteries is the origin of Imagine Breaker, since it is neither an esper ability nor a magical ability. Later in the series, whereas Touma's entire right arm is cut off a dragon head referred to as the Dragon Strike (竜王の顎（ドラゴンストライク） Ryūō no Ago Doragon Sutoraiku, "Jaw of the Dragon King") emerges. It should be noted that within Christian Church, the dragon represents to be of Divine origin according to two members of God's Right Seat. Fiamma believes Imagine Breaker is the Holy Right, which holds the power of miracles and Terra hints Imagine Breaker's full powers have yet to be unlocked; if it does, its powers would extend to Tōma's whole body and beyond and the second about the meaning behind his surname 'Kamijō' as it means "The One Superior To God (神上)" for God's Right Seat and "The One Who Cleanses God (神浄)" for Kaori Kanzaki and Aleister.
- Due to the troubles he faces with delinquents, Tōma is a skilled street fighter, is physically fit, and manages to outrun his opponents. As he faces espers and magicians, he combined his fighting skills (including using his powers) with his quick thinking to outmaneuver his opponents. Mikoto considers him to be extremely strong, having never beaten him despite having repeatedly challenged him (who before she beat him once during his fight to save Othinus from the entire world after she shocked him directly). However, his ability can only be effective when espers use their power on him directly, which is why he had a tough time against Accelerator, who uses his ability on projectiles.
- He also has a sixth 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 (禁書目録 (インデックス) Indekkusu)
- Voiced by: Yuka Iguchi (Japanese); Monica Rial (English)
- Index Librorum Prohibitorum ("List of Prohibited Books"), is one of the main heroines from the magic side and the titular character of A Certain Magical Index. She is a young nun from Necessarius (必要悪の教会 Hitsuyōaku no Kyōkai, "Church of Necessary Evil"), a branch of the Church of England. Index is small in stature and has a petite build. About 15 years old, she has thigh-length, silvery-blue hair with very white skin and large green eyes. She also wears a white robe with golden embroidery sewed onto every edge of it, the Walking Church, that prevents any injury on her, but it is later destroyed by Tōma when he touched it with his right hand, 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 Grimoires 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 devoted lamb protects the knowledge of the strong" (献身的な子羊は強者の知識を守る Kenshinteki na Kohitsuji wa Kyōsha no Chishiki o Mamoru). The Church says that the Grimoires take up 85 percent of her mind, so she only has 15 percent 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 his teacher Komoe that the human mind can store an unlimited amount of memories up to 140 years at least. 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, John's Pen (自動書記 (ヨハネのペン) Yohane no Pen, "Automatic Writing"), will be activated to allow her to use magic to cast high-class magic attacks such as St. George's Sanctuary (聖ジョージの聖域 (セントじょーじのせいいき) Seinto Jōji no Seīki, "Sanctuary of St. George") and Dragon's Breath (竜王の殺息 (ドラゴンブレス) Doragon Buresu, "Killing Breath of the Dragon King"). Her self-protection system will use the Feather of Light (光の羽 Hikari no Hane) 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. Her vast knowledge of the Index-Librorum-Prohibitorum within her mind makes her to be one of the most powerful characters so far and becomes very helpful to her friends in various situations using skills like Spell Intercept (強制詠唱 (スペルインターセプト) Superu Intāseputo, "Force Chant"), and Sheol Fear ((魔滅の声 (シェオールフィア) Sheōru Fia, "Voice of Destruction of Evil").
- 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 is also a selfish spoiled brat when together with Tōma. She is also abusive towards him and hypocritical in nature, chiding him for doing things she doesn't like, yet does the same things herself. She constantly jumps to conclusions without learning the circumstances first and constantly punishes Toma, wrongfully, by biting him or starting arguments with him, much to his confusion and exasperation. She also has a large appetite and uses any excuse to get food from anyone and likes watching an anime series called Magical Powered Kanamin. 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 since he has no idea about what kind of feelings he used to have with Index.
- When she returns to England, she is sought out by Fiamma who wants her knowledge and reactivates John's Pen mode through her remote control spiritual item. Later during her stay at Necessarius Headquarters at St. George Cathedral, she learns the bitter truth about Tōma when Fiamma reveals Tōma lied to her about his memories, which sends her on a rampage and grows angelic "Crimson Wings" and corners Stiyl (who tries to restrain her) with ease just by flapping her wings. She also has displayed the ability to summon legendary weapons and artifacts to attack, such as the "Sword of Freyr", the magic sword of the Harvest God from the Norse Mythology. After defeating Fiamma, Tōma releases Index's mind from Fiamma's control, apologizes to her, and both promises each other to meet again. At the end of volume 22, she returns to St. George Cathedral with Stiyl to learn what happened to Tōma.
- In New Testament, Index eventually reunites with Tōma when he reappears in Academy City after the events of the Third World War.
- Mikoto Misaka (御坂 美琴 Misaka Mikoto)
- Voiced by: Rina Satō (Japanese); Brittney Karbowski (English)
- Mikoto is one of the main heroines from the science side in A Certain Magical Index, as well as the main protagonist and the titular character of A Certain Scientific Railgun. Despite her rich background, Mikoto had a typical childhood.
- At a young age, she was discovered to be a Level 1 Electromaster (電撃使い (エレクトロマスター) Erekutoromasutā, lit. "Electricity User"), espers who have the ability to generate and control electricity, and see beyond the visible electromagnetic spectrum. She enrolled into Academy City to train her powers and worked very hard until her powers were ranked Level 5. As an electromaster, she can generate and manipulate electricity which she can use to shock opponents, hack into electronics like computer networks and security systems, and use electromagnetism to cling to surfaces or manipulate iron particles into a chain-sword whip. Mikoto's signature move is her ability to shoot metal projectiles such as coins at high destructive speeds, hence her nickname, "Railgun" (超電磁砲 (レールガン) Rērugan, lit. "Super Electromagnetic Cannon"). If she is in a bad mood, she will sometimes let out bursts of electricity describing her emotional stress, usually resulting in power failures or in worse cases, a thunder storm that causes citywide blackouts.
- Mikoto attends Tokiwadai Middle School. 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, even after experiencing permanent amnesia, nicknames her "Biri Biri" (ビリビリ, the Japanese onomatopoeia of electric shocks, "Zapper" in the English dub, "Sparky" in the English manga), ever since their first meeting before the events of the first novel when he first dissipated her electricity after he unsuccessfully tried to rescue her. 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 scientists 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 did not have the same power level as Mikoto, they were instead used in a 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 mentioned in the third novel and expanded upon in the Railgun manga. When all of her attempts failed, she contemplates letting herself be killed by Accelerator, as an unexpected variable to destroy Tree Diagram's calculations. However, it is not until Tōma intervenes and beaten Accelerator, proving Accelerator to be really weak, that the project is canceled and the remaining 9969 surviving Sisters are spared.
- After the events of the third novel, she eventually develops strong romantic feelings towards Tōma but is unable to express them due to her insecurities and the fact other girls are also interested in him, and he treats her like a tsundere. Even though she and Tōma tend to bicker and argue with each other, they share a friendly relationship. 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 in on the conversation on the other end 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; she is relieved that Tōma still remembers the incident with Accelerator and the Sisters. 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 from Russia, Mikoto heads to Russia after hijacking a jet from the Academy City Invasion Force (incidentally, said jet was ordered to find and capture Tōma). After arriving in Russia, she and Misaka 10777 head towards a nuclear military base to stop the missiles from launching. Near the end of volume 22, she tries to rescue Tōma from the falling Star of Bethlehem but he stays behind in order to stop an Archangel. After the Star's destruction, she tries to find him but only finds his cellphone strap.
- During the Daihasei Festival, Misaka 10032 is kidnapped by Gensei Kihara whose scheme is to gather the requirements for his attempts to make Mikoto a Level 6. Gensei required Exterior, the giant cultivated brain used by Misaki in order to infect the Misaka Network with the electric virus and get around its defenses. His forced attempt in creating a level 6 involves sending Mikoto's power out of control. At 53% of the theoretical limit her mind would transform into something from a different dimension. Afterwards, Mitori likely used the Exterior to guide Mikoto's psyche. She brings out her fears and anger towards the city, and has her attack the Windowless Building, saying bad things would happen and someone will always get hurt. Mikoto complies and uses her newfound power to make an incredibly powerful beam of electricity descend from the overcast sky, though the Windowless Building survives. Tōma, allied with Sogiita Gunha, are confronted by Mikoto's huge mass made of metal and rubble formed from various metal containing structures. Mikoto's subconscious wakes up, but she has no control over her transformed body, as the great black sphere of energy continues to grow, and energy exudes from the ground. The sphere's power was too great for Tōma's right arm to bear and it is ripped from his body intact. At that moment, the Dragon Strike in the form of eight other dragons emerges, and then bites the black spheres and makes Mikoto's transformation crumble. With Mikoto restored, Tōma comforts her by saying that there are people who are working to help her change bit by bit; she agrees with tears in her eyes.
- After the Third World War, Mikoto returns to Academy City feeling depressed over failing to save Tōma, but is relieved when she is reunited with him, as he survived after returning to Academy City. Later, she was one of the few who were involved in an operation in Hawaii. She intended to enroll in Tōma's school during the Ichihanaran Festival, though this was interrupted by Misaki Shokuhō.
- Accelerator (一方通行 (アクセラレータ) Akuserarēta)
- Voiced by: Nobuhiko Okamoto (Japanese); Austin Tindle (English)
- Accelerator is one of the main characters in the science side in A Certain Magical Index, and the titular character of A Certain Scientific Accelerator. He is the most powerful esper in Academy City, ranking at the top of the seven Level 5s in the city. His real name is unknown, though Accelerator recalls his surname was composed of two kanji characters and his given name consisted of three kanji characters. First appearing as an antagonist of the third light novel, he later becomes a main protagonist in the science side of the Toaru Majutsu no Index series in a notable number of volumes of the light novels. His name is written as "Ippōtsūkō", meaning "One-Way Road". His ability allows him to control any vector he touches including motion, heat, electricity, and wind. This allows him to perform various feats such as reflecting bullets, launching heavy objects, and even reversing the flow of blood in people's bodies. Since his natural ability blocks all ultraviolet radiation, he has an appearance with white hair.
- Accelerator's unique ability makes him the subject of an experiment attempting to create the first Level 6 esper: 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 Misaka Mikoto, the Railgun, 128 times without a single failure. Since it was impossible to procure 128 Railguns, an alternative plan was formed to "level up" Accelerator by having him kill 20,000 skilled Level 3 espers: the Misaka clones. 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. His desire to achieve this goal leads him to kill many who got in his way. 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 and his overconfidence in his esper abilities. Therefore, Tōma beat him with his Imagine Breaker and street-fighting skills.
- After his defeat in volume three of the light novels, he reappears in the fifth novel where his past was also revealed. He was taken to Academy City at a young age when his powers were first discovered but because of the lack in their understanding of his powers, people fear him and in some cases tried to kill him. Due to the many attempts on his life and the numerous experiments performed on him, these events shaped Accelerator into a sadist and made it difficult for him to trust anyone except for Kikyou Yoshikawa, the only scientist who ever cared about him and saved his life. He also takes a more heroic and fatherly role by protecting a young girl named Last Order, the last Misaka clone who believes through the memories of the Sister clones who fought him that Accelerator is not bad person and actually never wanted to hurt the clones but tried to merely intimidate them into not fighting him, a theory Accelerator dismisses. In the aftermath of the incident, Accelerator is shot in the head by Ao Amai and acquires aphasia due to brain damage. The injury also affects his ability but Heaven Canceller jury-rigs a choker-like device to his brain, allowing Accelerator to tap into the Misaka Network to make up for his injury and function normally. He can also switch the transmitter to full power, restoring his ability for a maximum of 15 minutes at the beginning, but the time is later extended to 30 minutes by an update to the device. Toward the end of volume 13, Accelerator begins to "awaken" after nearly being killed by Amata Kihara and his aphasia is somehow temporarily cured. He 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 "Goatskin", a mysterious document sought after by both Academy City and the Russian government that has the knowledge about the Archangels and Heaven, and later runs into a Misaka Worst clone, learning that Aleister intends to eliminate Last Order, now obsolete to create a new Misaka network. Despite being more powerful than Misaka Worst, Accelerator is unable to bring himself to harm another Sister clone after the Level 6 experiment and becomes mentally unstable after the clone attempts to kill Last Order and later tries to kill herself. Accelerator goes on a rampage until Tōma arrives where he 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 joins forces with Elizarinian soldiers and Misaka Worst to find spies in their country, and fought Archangel Gabriel along with Hyōka, where after studying the Goatskin, he learns to understand the angel's language and turning himself into an angel as a side effect. With his new powers, he is able to decode one of Index's songs and was finally able to cure Last Order but is injured in the process.
- After the Third World War, Accelerator is given his freedom with the help of Shiage, after he threatens the Academy City's administration to leave him, Last Order and Misaka Worst alone and orders them to stop all illegal black projects in the city. However, both he and Shiage actions anger a new group of espers called the "Freshmen" who are aware of the existences of Magic and sees them as an obstacle in Academy City's war against the Magic factions. After being helped by Tōma and Leivinia Birdway, the latter invites him to join the world of Magic.
- Shiage Hamazura (浜面 仕上 Hamazura Shiage)
- Voiced by: Satoshi Hino (Japanese); Clifford Chapin (English)
- Shiage is one of the main characters in the science side in A Certain Magical Index he is a former member of Skill-Out, a group of Level 0s who use various means to counter esper abilities, who accidentally gets caught up with the Dark side of Academy City. He is first introduced in the Side Story novels where he became the leader of his Skill-Out gang after Accelerator killed the former leader, his best friend Ritoku Komaba on the orders of the Board of Directors. On the same day he became the new leader, his gang was forced by the Board of Directors to kill Mikoto's mother, Misuzu or face extermination. However, he and his gang were defeated by Tōma and Accelerator and they failed to kill Misuzu. 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 one of their members, Rikō Takitsubo.
- During the 15th novel, Team ITEM is involved in a war between the various underground organization where Shiage helps them by providing transport by stealing cars around the city. But when Team ITEM is defeated by Team SCHOOL led by its leader, Teitoku Kakine, Shizuri Mugino, the leader of Team ITEM, wants revenge for being humiliated no matter what and forces an injured Rikō to use her powers to find Teitoku despite the fact that repeated use of her powers will kill her. In order to save Rikō, Shiage fights against Shizuri and despite the odds, he manages to defeat Shizuri by using her pride and powers against her. However, this unexpected incident becomes a thorn in Aleister's plans as there was no way Shiage could defeat Shizuri as she is a Level 5. Seeing him as a unpredictable anomaly that will disrupt his future plans, Aleister puts a bounty on Shiage and orders the forces of Academy City's dark side to kill him. Ironically, he is saved by Shizuri, who survived their battle and now has a sense of twisted love for him (declaring she will castrate him as her sign of affection). She lets him and Rikō escape Academy City by stealing a jet and shoots down his pursuers, declaring that he is her prey and hers alone.
- Shiage and Rikō escapes to Russia only to find themselves in a war between Academy City and Russia. After being saved by Acqua of the Back, Shiage and Rikō heads to the nation of Elizarina where Rikō is partially healed by Accelerator and aids Acqua. In order to protect a document called the Kremlin Report, Shiage and Rikō heads towards the same nuclear military base that Mikoto went while they were being chased by Academy City forces and later Shizuri. However Shizuri collapses from over-exhaustion as her fragile body is suffering from the effects of using too much Body Crystal, a dangerous drug that Rikō uses to activate her powers. Unable to see her this way, Shiage begs Shizuri to let go of her pride and see reason and be the Shizuri that use to care for her teammates which strokes a cord within her and makes peace with him as she protects him and Rikō from the rest of the invading Academy City forces. After capturing a member of the Board of Directors who led the Academy City forces and torturing him, he reveals to Shiage a document called the Parameter List, which reveals that the Academy City administration has been secretly interfering with the Power Curriculum Program and preventing most of the city's students from gaining or raising their powers.
- After the Third World War, Shiage is given amnesty and the assassination order on him removed thanks to Accelerator and makes a deal with the Academy City's administration, where he will not expose the truth about the Parameter List and he, along with Rikō and Shizuri are allowed to return to Academy City to reform Team ITEM. However, his and Accelerator's actions have made them enemies with a new group of espers called the "Freshmen" which is aware of the existence of Magic who sees both of them as an obstacle in Academy City's war against the Magic factions. After Tōma and Leivinia help him and Accelerator against the "Freshmen", Tōma introduces them to the world of Magic.
A Certain High School
The unnamed high school that Tōma and his friends attend.
- Motoharu Tsuchimikado (土御門 元春 Tsuchimikado Motoharu)
- Voiced by: Anri Katsu (Japanese); Newton Pittman (English)
- Motoharu is a blonde teenager who is always seen with sunglasses and wearing an Aloha shirt. He is one of Tōma's best friends and classmate who just happens to be his next-door neighbor at the dormitory they're staying at. He calls him "Kami-nyan". He unashamedly has a crush on his adopted sister Maika and often ends his sentences with 'nya' (the Japanese equivalent of 'meow'.) While he seems like a normal, average teenager, 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 not take action. His sorcery name is Fallere825, "The Back-stabbing Blade" (背中刺す刃 Senaka Sasu Yaiba).
- Motoharu is a skilled Onmyōji as his family are descendants of Abe no Seimei, but as he went under the esper development curriculum, using any magic would cause intense damage to his body. He was ordered by the church to infiltrate Academy City. To avoid suspicion, an artificial family was created with Ashiya Touzu and Urabe Bishu acting as his parents, while he adopted a younger sister named Maika from an orphanage outside of the City. Despite the efforts, he was exposed within 36 hours and turned into a double agent to ensure his survival. He is in love with Maika, and for this he is known as the Shisukon Gunsō (シスコン軍曹 "Sis-con Sergeant"). He is also a member of one of Academy City's secret organizations, "GROUP". His esper ability is Level 0 Auto-Rebirth (肉体再生 （オートリバース） Ōto Ribāsu, lit. "Body Regeneration"). Due to this power, he can still use magic as he can repair the damage done to his body, making him the only successful esper-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 and the fact that his esper ability can fail at any time.
- Motoharu was first majorly involved in Angel Fall, and discovered that Tōya was the one who accidentally casted Angel Fall. Motoharu said that himself would need to be sacrificed to stop Angel Fall, as he fought and defeated Tōma who tried to stop him and successfully destroyed the ritual location. However, he revealed later on that he survived through his esper abilities. Motoharu also played a big role during the Daihasei Festival, helping Tōma looking for the Stab Sword and later providing information through casting a magic spell to determine Oriana's location after being injured by Oriana, and was later defeated by Oriana for the second time. He then regroups with Stiyl and Tōma to destroy Croce di Pietro in 23rd School District, but was caught in a trap and forced to see out Stiyl and Tōma fight Oriana. Motoharu travels to France along with Tōma to stop the activation of the Document of Constantine, but was split up from Tōma when they jumped out of the plane, and only reappears when Tōma and Itsuwa was fighting Terra of the Left, and helps them destroy rampaging Academy City forces. During Battle Royale he was tasked along with GROUP to stop SCHOOL and BLOCK's revolution, GROUP has successfully ruined BLOCK's attempt to bring in mercenaries from outside Academy City and Motoharu was defeated by Megumi Teshio. Later he retrieved the Pincet Glove during Accelerator's fight with Teitoku and with it he discovered the existence of DRAGON thus he looks into it, before getting knocked out by Aiwass after his manifestation.
- After learning that Maika might be used as a bargaining chip against him, he faked her death by burning her apartment and went investigating the people behind Agitate Halation. He fooled Tōma, who he thinks would cause most interference to his plan, into investigating a magician in the School Garden. He found Hisako Yakumi, who was able to convince him that she wasn't the mastermind behind this project, and confronts Seria Kumokawa has Tsugutoshi Kaizumi instead. Seria successfully shot Motoharu and he was eventually defeated by Tōma who has escaped the School Garden, and discovers that Hisako Yakumi is indeed the mastermind behind the project. After these events, Seria was sent to execute Motoharu, but she has fired paint rounds containing his blood instead and knocked him down to the river. He is officially considered dead on paper by Academy City.
- Pierce Aogami (青髪 ピアス Aogami Piasu, lit. "Blue hair and piercings")
- Voiced by: Yoshihisa Kawahara (Japanese); Scott Freeman (English)
- One of Tōma's best friends and classmate whose real name is unknown, and was considered strong by Tōma before Tōma's memory loss. Despite never been seen doing much class work, he is surprisingly the class representative. A funny individual who tends to notice Tōma's bad luck, and has calls him "Kami-yan" in a different way. He is a self-confessed pervert, lolicon, masochist, as well as numerous other fetishes who enjoys being punished by his teacher, Komoe. He is frequently seen with Motoharu. He, Motoharu, and Tōma are known as the "Idiot Trio" in their class as they have the lowest test scores, often requiring to sit for remedial lessons, although he has noted that he fails his tests on purpose to get punished by Komoe. He is frequently questioned by the authorities as it was revealed that he has been questioned 43 times in the current year. Despite his almost dumb nature, he is known to be powerful, Tōma once said that no one can mess with him. Fans suggest he and the mysterious Number Six Esper named Etsu Aihana are the same.
- Seiri Fukiyose (吹寄 制理 Fukiyose Seiri)
- Voiced by: Ayumi Fujimura (Japanese); Skyler McIntosh (English)
- Tōma's classmate and Aisa's best friend. She is often seen taking up roles of the class representative instead of Pierce, the actual class representative. She hates people who give up on their lives and blame their bad luck like Tōma, yet she secretly has a crush on him, acting like a tsundere when she is with him. She is described as a girl who is "pretty but lacks sex appeal". A health-product freak, she is frequently ordering different health products from shopping channels. Her abilities have yet to be revealed.
- Aisa Himegami (姫神 秋沙 Himegami Aisa)

- 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 (吸血殺し (ディープブラッド) Dīpu Buraddo, "Vampire Killer"), possessing 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, 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. It is later revealed that Aisa is a Gemstone, a codename for espers who were born with unique powers.

- Introduced in the third story arc of the series, they are Mikoto Misaka's clones. Unlike Mikoto, they seem rather quiet and emotionless, their voices are rather monotonous and computer-like, and they speak in third person by adding a description of themselves after every sentence. In addition, 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 do not 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 esper ability called Radio Noise (欠陥電気 (レディオノイズ) Redio Noizu, "Flawed Electric"), 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 have not learned 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, it was intended that 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 used 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 esper, Accelerator. By the time of third novel, 10,031 were killed in the experiment before it 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 own 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.

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 during his fight against 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 will not mistake her for the original Mikoto), which she treasures.

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. Her name is written as "Uchidome", meaning "The End".
- 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.

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.

- Misaka 9982 (ミサカ9982号)
- Voiced by: Nozomi Sasaki (Japanese); Brittney Karbowski (English)
- Introduced in A Certain Scientific Railgun S, she was the first Sister clone Mikoto met. While she was similar to the other clones, 9982 had a rather unusual personality, 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.
- Misaka Worst (番外個体 （ミサカワースト） Misaka Wāsuto)
- 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 3 espers and were designed as combat units, these new clones are 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 1st generation clones, who show little emotion. Academy City deploys one of the Misaka Worst in their war against Russia, where she attempts to assassinate Last Order. Accelerator tries to stop her without killing her as he does not 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. Their names are written down as "Bangai Misaka" ("Extra Misaka").

This irony means that she is often regarded as one of the seven great mysteries of Academy City. As a teacher, she doesn't have any esper abilities and is capable of assisting in magic spells, assisting Index when healing herself and assisting Stiyl when Aisa gets injured by Oriana. Her name is an aptronym as the character "小" means "small" and the character "萌" means "moe".

- Voiced by: Toshihiko Seki (Japanese); Chuck Huber (English)
- Based on Aleister Crowley. He was once the greatest magician in modern magic history, where more than half of all modern magicians are affected by this man's established theories, and two-fifths of them are direct followers of his ways. Aleister stretched the boundaries of sorcery farther than the advances made in the last few millennia alone and written many top-class spellbooks like The Book of the Law. His death in 1947 shocked many but it was not the last the world had heard of him. In reality he faked his death to stop his obsessed fanatics following him and secretly went to Japan where during his journey, he met a doctor who he would later call Heaven Canceller. Years later, Aleister, Heaven Canceller and several powerful individuals combined their resources and influences to create one of the most technologically advanced city on Earth at western Tokyo, Academy City. By this time, rumors of Aleister still being alive led some mages to discover the truth. At first they were happy to see that he was alive but were immediately shocked as that not only Aleister abandoned using magic but was more interested in the study and development of espers.
- To this day, only a few magicians know Aleister is still alive who are mostly the leaders of powerful magical organizations and their trusted followers and those that do know him view him with skepticism, curiosity on what he's doing or outraged for abandoning magic and supporting science especially esper studies. 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 Superintendent 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.

Styl appears as 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.

Despite the lies, he remains with Necessarius and becomes the assistant to the Archbishop of Necessarius herself.

She uses a two-meter-long nodachi called "Seven Heavens Seven Swords" as her weapon. She has a special attack called Nanasen (七閃, "Seven Flash") that uses her sword and some wires. She is to be a kind woman who treats Index like a sister, but when Index's memories are erased by Necessarius, Kaori becomes a ruthless and silent woman as Index is unable to remember her and consequently distrusts her. After Tōma rescues Index 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 leaves the group as she resents that she has been fated since birth to become its leader, which leads to her resenting the concept of luck and fortune. Though she is Catholic, she joins 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 results in Kaori beginning to accept that no matter how much a person tries, no one can change their destiny. However, Kaori begins to show a kinder side to herself after Tōma rescues Index, giving her hope that anyone can defy their destiny, and eventually falls in love with him after he helps her reunite with the Amakusa Catholics, becoming more prone to showing emotion and sometimes showing a little embarrassment if she is with him.
