She is a member of ITEM, led by Mugino Shizuri.  ~!She later becomes its leader in Volume 19, after Shizuri's defeat in Volume 15 at the hands of Shiage Hamazura.!~  Despite being a powerful Psychic, Saiai is one of the most mellowed-out characters in the group; she isn't a screw-up like Frenda, nor is she as frightful as her leader, Mugino. She enjoys bad movies and likes to tease others, Shiage in particular because of his reaction to anything sexually suggestive.  She also likes to add "super" (超, chou) to her remarks.   Her ability is the Level 4 Offense Armor (窒素装甲, Chisso Soukō?, lit. "Nitrogen Armor"), which she uses to control the nitrogen in the atmosphere to create a few centimeters of solidified nitrogen to act as a barrier. She can use this to attack and defend. Like Accelerator's AIM vector shield, the primary function of her ability is to create an armor of super-compressed nitrogen around her, she fights a sniper in volume 15 and Academy city's special sniper rifle is shown to have no effect on her other than to knock her backwards a little. Because of her ability, she carries around a small amount of nitrogen for use at all times.    ~!According to Teitoku Kakine, Saiai is a leftover from 'Project Mayday of Darkness' (usually referred to as the "Dark May Project") whose aim was to create a personal version of Accelerator's ability by using a similar pattern of ability operation. This was done by referencing the cognitive patterns of Accelerator himself in order to optimize the personal realities of certain espers taking part in the experiment. Though the details are not mentioned, Saiai only succeeded in creating an automatic self-defense capability that activates if she is attacked.!~

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.

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.
