List of A Certain Magical Index characters

The following is a list of characters from A Certain Magical Index light novel, manga and anime series, and its side-story manga and anime series titled A Certain Scientific Railgun and A Certain Scientific Accelerator, as well as a number of spin-off media. The series primarily takes place in Academy City, a city filled with students who strove to become powerful espers and were brought into conflict by the appearance of sorcerers.
Toma Kamijo (上条 当麻, Kamijō Tōma) is a first-year high school student and a Level 0 esper, yet has an ability called "Imagine Breaker" (幻想殺し, Imajin Bureikā, lit. "Illusion Killer") in which he uses his right hand to negate abilities whether they are magic or scientific. Upon meeting Index, Toma becomes involved in major events that take place in A Certain Magical Index franchise. With his frequent encounters with Mikoto Misaka, Toma has also been involved in major events in A Certain Scientific Railgun franchise.
Mikoto Misaka (御坂 美琴) 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. She is Academy City's third most powerful Level 5 esper with an ability called "Railgun" (超電磁砲, Rērugan, lit. "Super Electromagnetic Cannon") which allows her to produce one billion volts of electricity, making her the most powerful Electromaster in Academy City.
Index Librorum Prohibitorum (禁書目録, Indekkusu), also known as Index, is a fifteen-year-old English nun from Church of England's Necessarius, with Dedicatus545 ("The devoted lamb protects the knowledge of the strong") as her magic name. She is always seen wearing the Walking Church, a white robe with a golden embroidery sewn on every edge of it (later with golden pins after it is destroyed by Toma Kamijo with his Imagine Breaker). Index's mind has been implanted with 103,000 grimoires of the Index Librorum Prohibitorum since she possesses photographic memory and is the only magician who can read grimoires that are deadly to a normal magician or individual. She has a self-protection system personality called "John's Pen" (自動書記, Yohane no Pen, lit. "Automatic Writing") which allows her to cast high-class magic attacks such as St. George's Sanctuary (聖ジョージの聖域, Seinto Jōji no Seīki) and Dragon's Breath (竜王の殺息, Doragon Buresu, lit. "Dragon King's Killing Breath"). Her self-protection system has a by-product called "Feather of Light" (光の羽, Hikari no Hane) which forces a reset on her memory in case a manual reset fails to be performed. Although she does not know that she has magic abilities, Index 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 one of the most powerful characters so far and becomes helpful to her friends in various situations like using Spell Intercept (強制詠唱 (スペルインターセプト), Superu Intāseputo, lit. "Force Chant") and Sheol Fear (魔滅の声, Sheōru Fia, lit. "Voice of Destruction of Evil") in the fight against the battle nuns of the Roman Catholic Church led by Agnese Sanctis.
Index is often elated by a variety of things and is slightly ignorant and curious about 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 Toma. She is also abusive towards him and hypocritical, 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. Index also has a large appetite and likes watching an anime series titled Magical Powered Kanamin. She has strong feelings toward Toma and even confessed her love after hearing Toma 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, Index is sought out by Fiamma of the Right, who wants her knowledge, and is reactivated in her John's Pen mode by her remote control magical item. Later during her stay at Necessarius' headquarters in St. George Cathedral, Index learns the bitter truth about Toma when Fiamma reveals him lying to her about his memories, which sends her on a rampage and grows an angelic Crimson Wings that corners Stiyl Magnus, 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 Norse god of the same name. After defeating Fiamma, Toma releases Index's mind from his control, apologizes to her, and both promise each other to meet again. At the end of the twenty-second volume of A Certain Magical Index, Index returns to St. George Cathedral with Stiyl to learn Toma's condition. In A Certain Magical Index: New Testament, Index eventually reunites with Toma when he returns to Academy City after the events of World War III. She later joins Toma, Accelerator, Shiage Hamazura, Rikō Takitsubo, and Aleister Crowley during the latter's invasion of London, where she learns another grimoire for a total of 103,001. She also engages in a fight with Mikoto Misaka during a conflict between Toma and his doppelganger in Windsor Castle. In A Certain Magical Index: Genesis Testament, Index returns to Academy City with Toma in time for a Christmas holiday but is later sent on a mission to investigate the disappearance of residents in Los Angeles.
Kuroko Shirai (白井 黒子) is a first-year student and Mikoto Misaka's kōhai. She is one of the main protagonists of A Certain Scientific Railgun. Kuroko is a Level 4 esper with an ability called "Teleport" (空間移動, Terepōto, lit. "Spatial Movement") which allows her to teleport herself or objects she touches under a total weight of around 130–137 kilograms (287–302 lb) to anywhere within a radius of around 81–85 metres (266–279 ft), but her ability it requires an amount of concentration for successful execution. She is a member of Judgment and generally carries a strap of nails around her thighs, which she used during her work to pin down enemies. Kuroko has an obsessive and perverted crush on Mikoto, whom she addresses as "Onē-sama" (おねえさま, revered big sister) or "Sissy" in the anime series' English dub. She is on the constant lookout for a chance to get physically intimate with her, which ends up in her being electrocuted. She gets jealous of other people who got Mikoto's attention, mostly Toma Kamijo. Kuroko officially debuts in the eighth volume of A Certain Magical Index when she investigates a robbery of the remnants of the Tree Diagram and discovers Mikoto's involvement in the incident. She gets injured by Awaki Musujime during their fight in a restaurant, but she is later saved by Tōma and Mikoto before Awaki can unleash an enormous teleported mass on her. After the events surrounding the Tree Diagram, Kuroko is confined to a wheelchair for some time because of the injuries she sustained from the battle. In A Certain Magical Index: Genesis Testament, Kuroko works with Anti-Skill to apprehend the members of the dark side organization during Operation Handcuffs and later teams up with Toma, Alice Anotherbible, and Yōen Hanatsuyu to stop the rampage of Frillsand #G following the conclusion of the operation.
Accelerator (一方通行, Akuserarēta) is one of the central characters in the science side in A Certain Magical Index, as well as the main protagonist and titular character of A Certain Scientific Accelerator. He is the most powerful Level 5 esper in Academy City with an eponymous ability that allows him to control any vector he touches, ranking him at the top of the seven Level 5s in the city. Since his natural ability blocks all ultraviolet radiation, he has an appearance with white hair. His name is written as "Ippōtsūkō", meaning "One-Way Road". His real name is unknown, though Accelerator recalls his surname is composed of two kanji characters, and his given name consists of three kanji characters. First appearing as an antagonist in the third volume, he later becomes the main protagonist in the science side.
Accelerator's unique ability makes him the subject of an experiment attempting to create the first Level 6 esper, in which according to the city's best supercomputer known as the Tree Diagram (which is destroyed by Index's Dragon Breath), this feat can only be achieved by killing Misaka Mikoto 128 times without a single failure. Since it is impossible to procure 128 results out of a single target, an alternative plan is formed to "level up" Accelerator by having him kill 20,000 of her clones. He willingly joins the experiment to gain a reputation as the most powerful and feared esper so that no one can be foolish enough to challenge him. His desire to achieve this goal leads him to kill many who gets in his way. Mikoto tries to stop the experiment to save her clones, but it is Toma Kamijo who finally does so and defeats Accelerator after discovering his weakness of being physically weak because of his total reliance on his powers and his overconfidence in his esper abilities. Therefore, Toma beat him with his Imagine Breaker and street-fighting skills.
The fifth volume reveals his past where he is taken to Academy City at a young age after his ability was first discovered but because of the lack of understanding, people fear him and in some cases attempt to kill him. Due to the many attempts on his life and the numerous experiments performed on him, these events shape Accelerator into a sadist and makes it difficult for him to trust anyone except for Kikyō Yoshikawa, the only scientist who cares about him and saves 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 a bad person and 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 in the beginning, but the time is later extended to 30 minutes by an update to the device. Toward the end of the thirteenth volume, Accelerator begins to "awaken" after nearly being killed by Amata Kihara and his aphasia is somehow temporarily cured. He truly "awakens" in the fifteenth volume, gaining black wings when fighting another "awakened" Level 5 esper, Teitoku Kakine. In the events of the nineteenth volume, 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's 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 contains knowledge about the Archangels and Heaven, and later runs into a clone known as Misaka Worst, 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 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 Toma arrives where he turns his frustration regarding Last Order's condition into him and a fight ensues between the two. After Accelerator is defeated again, Toma 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 fights Archangel Gabriel along with Hyōka Kazakiri, where after studying the Goatskin, he learns to understand the angel's language and turns himself into an angel as a side effect. With his new powers, he can decode one of Index's songs and is finally able to cure Last Order but is injured in the process.
After World War III, Accelerator is given his freedom with the help of Shiage Hamazura, 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 Toma and Leivinia Birdway, the latter invites him to join the world of magic and brings him in an operation in Hawaii. With the apparent death of Aleister Crowley against and the full authority of the Board Chairman from the dying Aleister Crowley, become the new Board Chairman of Academy City.
Shiage Hamazura (浜面 仕上) 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 an 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 escape to Russia only to find themselves in a war between Academy City and Russia. After being saved by Acqua of the Rear, Shiage and Rikō head 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 head towards the same nuclear military base that Mikoto went to 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 is 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" who 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 and involved in an operation in Hawaii.
Teitoku Kakine (垣根 帝督) is the leader of SCHOOL. He is Academy City's second most powerful Level 5 esper with an ability called "Dark Matter" (未元物質, Dāku Mat, lit. "Unknown Matter") which allows him to create and control an unknown matter unbounded by laws of physics. Teitoku is Aleister Crowley's spare plan if Accelerator fails to meet his expectations, which he finds undesirable. He later sparks a revolution by orchestrating an assassination attempt on Monaka Oyafune to disrupt the security in Elementary Particle Engineering Laboratory that houses the Tweezers. Teitoku plans on using it to grab a minuscule machine called "UNDER_LINE" that serves as Aleister's sole method of collecting information while inside the Windowless Building, helping him contact the Board Chairman. However, he decides to kill Accelerator instead because he has not gained any leverage to serve as a bargain for Aleister. Teitoku then tortures Kazari Uiharu for information about Last Order's location when Accelerator shows up. The two engage in a fight, during which they both become awakened by their hidden powers, until Accelerator hardly beats Teitoku, ripping apart most of his body. His brain is later preserved in Dark Legacy, a tool created by Heaven Canceller which rapidly reproduces cells to keep anything alive. Teitoku returns in the sixth volume of A Certain Magical Index: New Testament when he manages to recreate his body. During the Ichihanaran Festival, he is requested by Yuītsu Kihara to capture Fräulein Kreutune. He summons Dark Matter-made Japanese rhinoceros beetles called "White Beetle" to hunt down her while he fights Accelerator for his revenge. However, one of the White Beetles loses its programmed command because of Rikō Takitsubo's AIM Stalker ability and starts to take over the system, becoming the new Teitoku named Beetle 05 which possesses a caring personality. The original Teitoku is taken by Ollerus, who disguises himself as Thor, to create the Lance of Gungnir for GREMLIN.
He is also the protagonist of his own spin-off series A Certain Scientific Dark Matter.
Misaki Shokuhō (食蜂 操祈) is a second-year student who led the largest clique in the school, earning her the title "The Queen of Tokiwadai". She is Academy City's #5 Level 5 esper with an ability called Mental Out (心理掌握, Mentaru Auto, lit. "Psychological Control") that used remote controls hidden in her sling bag to execute her mind-related powers such as mind read, telepathy, brainwashing, psychometry, and memory erasure. However, her power has setbacks such as she cannot use it on Electromasters, animals and machines, and especially Tōma Kamijō. Misaki does not trust anyone whose minds she could not read, except for Tōma. She prefers to hide from the public so she sends her follower or a mind-controlled individual as her representative instead.
Misaki is involved in the Exterior Project that would greatly boost her power by cultivating a cut portion of her brain's cerebral cortex. She is then requested by researchers of the Clone Dolly Project to act as Dolly's missing friend aliased "Mi-chan" by altering her memories that would make Misaki the friend in her mind. Misaki eventually learns about the researchers' plan of disposing of her upon the Exterior's completion. She decides to brainwash the scientists involved in the project and take over the building.
Misaki's backstory makes a debut in the eleventh volume of New Testament: A Certain Magical Index light novel series when she bumped into Tōma for the first time at an intersection road during her early days as a first-year student. She then meets him several times during the summer and receives a cheap whistle from him to be used for emergencies, which she greatly treasured. Their meeting is short-lived when Misaki was targeted by an organization called "Deadlock", causing Tōma to get badly injured after he protected her from their attacks using his body. Misaki uses her power to manipulate his brain's fluids, which would cut off his sense of pain and lets the EMT continue treating him, but she finds her treatment ineffective because of his low blood pressure, leaving him brain damage that caused him unable to remember or make memories with her.
In the Ichihanaran Festival story arc, Misaki prevents Mikoto Misaka from taking a trial enrollment in Tōma's high school by making mind-controlled individuals chase after her. She then competes in a swimsuit contest against Seria Kumokawa. In the Agitate Halation story arc, Misaki helps Tōma in finding the magician who infiltrated the School Garden. She later joins Tōma in London along with Mikoto as he confronts the Golden Dawn magic cabal during the Coronzon story arc. Misaki is heavily involved in the Kamijō story arc as she becomes mentally unstable due to her confusion between Tōma's doppelganger, who could remember her, and the real one, who retained the brain damage that prevented him from remembering or making memories with her. Misaki is last seen in a hospital where she was confined because of the injuries she sustained from her fight against Anna Sprengel to acquire the vaccine for a dying Tōma.
She is also the protagonist of her own spin-off series A Certain Scientific Mental Out.
