Profile:
She is an eighteen-year-old Japanese sorceress from Necessarius (the secret magical branch of the Anglican Church) and her sorcery name is Salvare000 , "Be the salvation of those who cannot be saved" (救われぬ者に救いの手を Sukuwarenu Mono ni Sukui no Te o).

Ability:
She uses magic to magically strengthen her body and 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. Not only is Kaori a skilled swordswoman but she is a Catholic Saint possessing the "Stigma" — the ability to call upon God's power.

Character:
Though she is Catholic, she joined Necessarius in hopes of changing her fate and befriended Index, developing a sisterly relationship with her. She used to be a kind woman who treated Index like a sister, however, 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. 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. She was the former leader of the Amakusa Catholics however, she 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.

She is also the protagonist of her own spin-off mini light novel.

AKA as Misaka Imōto, she is the most prominent clone that is most featured in the series and is known for having a soft spot for cats, while she herself has a pet black kitten. She was the second sister clone that Touma met.

Introduced in the third story arc of the series, they are Mikoto Misaka's clones, which Touma refers to as Misaka's little sisters (御坂妹; Misaka imōto).

Unlike Mikoto, they seem 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 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 psychic ability called Radio Noise (欠陥電気 Kekkan Denki, "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 psychic, 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.

Mikoto Misaka (御坂 美琴) is one of the series' main heroines, as well as the main protagonist of the side story, A Certain Scientific Railgun.

At a young age, she was discovered to be a Level 1 Electromaster, espers who have the ability to generate and control electricity, and see beyond the visible electromagnetic spectrum. 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 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.

She enrolled into Academy City to train her powers and worked very hard until her powers were ranked Level 5, the highest esper ranking, with her being the third strongest of the seven espers with this rank.


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, "The Railgun".

Touma Kamijou nicknamed her "Biri Biri" (ビリビリ) -- the Japanese onomatopoeia of electric shocks.
