Yomikawa Aiho is teacher at Touma's school and a friend of Komoe. She is beautiful, has glamorous proportions, and is always seen with a green jersey and often ends her sentences with "-jan". Despite having a glamorous figure, she acts in a tomboyish matter and regularly joins colleague Tsukuyomi Komoe in drinking sessions after their work. She also always tease Komoe, her senior &amp; friend.  She is a member of Anti-Skill and cares deeply for her students (in spite of having a "spartan" approach in teaching according to Komoe), and is an active peacekeeper within Academy City. Due to her habit of ramming delinquents with protective items like shield or helmets to resolve incidents, saying it's alright to do so since those are protective items, she's known as 'the woman who uses comedy-like methods to solve problems that could end up as a tragedy'.  As a favor to her old friend, Yomikawa is asked by Yoshikawa Kikyou to take care of Accelerator and Last Order after they are released from the hospital.   ~!Yomikawa suspects that Accelerator is involved in Academy City's dark side, which he does not deny, but instead calls Yomikawa naive for thinking the things that barely scratch the surface are the worst that things can get. Later she brought Accelerator back out of the dark side briefly, before he got dragged back by Kakine and got herself stabbed by Dark Matter.  In New Testament, when Accelerator came back, it was said that she punched him and then hugged him.!~

Academy City is a highly developed place in terms of technology. It is said to be 20 to 30 years ahead of the rest of the world, and 80% of its 2.3 million residents are students. The focus of studies here is directed towards esper powers. Misaka Mikoto, one of the top level espers in town, shares a room with Kuroko Shirai, another high level esper who is a member of Judgement, a law enforcing agency composed of students. Both attend Tokiwadai, a private school reserved for the high-leveled and the rich. Kuroko's partner at Judgement, Kazari Uiharu, is a low level esper who studies at Sakugawa middle school. Her best friend and classmate there is Ruiko Saten, a level zero, one who has no esper powers. Together, the four encounter several adventures in the exciting scientific town.

The second season of Toaru Kagaku no Railgun. 
 
Something sinister is going on in Academy City. The shadows are filled with whispers of an organization cloning super-powered students known as espers. High-ranking master of electricity, Mikoto Misaka, laughs off these stories until she comes face to face with a copy of herself. After learning that these clones - her sisters - are being systematically murdered in a series of experiments designed to turn a sadistic killer into the strongest esper in history, Misaka vows to save her copies and destroy the organization responsible for the project. 
 
As Misaka prepares to face off against the organization’s power-hungry esper, she discovers that she wasn’t the only victim of the scientific forces conspiring within the city - and that’s something Misaka and the girls of Judgement simply won’t stand for.

Set in a city of scientifically advanced superhuman students, but in a world where magic is also real. Touma Kamijou&rsquo;s right hand, the Imagine Breaker, will negate all magic, psychic, or divine powers, but not his own bad luck. One day he finds a young girl hanging on his balcony railing. She turns out to be a nun from the Church of England, and her mind has been implanted with the Index-Librorum-Prohibitorum - all the magical texts the Church has removed from circulation.

Index is still a fugitive, and many powerful magical organizations and individuals want to take her to use the books in her memory, eliminating her in the process. War between those organizations is also starting to emerge. Index can only rely on her friend Touma, who has always protected her, along with Misaka and other friends from the Academy.

The espers of Academy City are classified into six levels, where "Level 0" lacks power while "Level 5" possesses an overwhelming amount. Of the several million espers residing in Academy City, only seven of them have attained Level 5, and ranked highest among them is the one known as Accelerator. 

Toaru Kagaku no Accelerator focuses on the strongest Level 5 after he protects the cheerful Last Order at the price of much of his power. Recovering at the hospital, Accelerator has led a relatively quiet life until he ends up saving the life of Estelle Rosenthal, a mysterious girl carrying a photo of Last Order. Unfortunately, Accelerator now finds himself dragged into a new conflict in the form of a sinister organization called Disciplinary Action which plots to use Last Order for a dangerous mission. Now that they have set their plan into motion and are in pursuit of the young girl, it's up to the world's most powerful esper and his newfound companion to protect Last Order and defend Academy City in the process.

Science and magic exist side by side in this world. 
This is the peak of the science side with a curriculum for espers, Academy City. In this city where 80% of the population are students, the season has finally come when all residents are excited and fidgety! 
It's Christmas Eve. 
Amidst the city showing a cheerful hustle and bustle, ordinary boy who can’t keep up with school, Kamijou Touma, also doesn’t intend to miss this event! He was hard at work in his supplementary lessons... 
A backward glance from the default misfortune-prone bastard, the silver-haired sister freeloading in his dormitory, Index, in the heart pounding scene different from the usual, activates a new gluton skill!? While Kamijou tries to desperately stop that, Misaka Mikoto taken in by the Christmas Eve atmosphere appears before him.

The story is set in a world where supernatural powers exist through science, and magic exists through religion. 
In the story, Touma Kamijou is an ordinary high school boy with terrible academic scores and a power called Imagine Breaker. Imagine Breaker can defeat any other power, but it also undermines Kamijou's own good luck. His Imagine Breaker's immense strength is literally immeasurable, so hapless Kamijou is listed at the supernatural level of 0. He happens to meet a girl in white hanging off his window balcony. The girl says she is being chased by sorcerers, and Kamijou learns that the girl is a Church of England nun whose memories have been forcibly replaced by Index-Librorum-Prohibitorum &mdash; the 103,000 forbidden texts of the Church.
