She is always seen wearing the Walking Church, a white robe with a golden embroidery sewn on every edge of it. 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" which allows her to cast high-class magic attacks such as St. George's Sanctuary and Dragon's Breath. Her self-protection system has a by-product called "Feather of Light" 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 and Sheol Fear 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.

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.

' 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" which allows her to teleport herself or objects she touches under a total weight of around to anywhere within a radius of around, 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" 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 has been a wheelchair user 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
' 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, 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.
