Origin
Academy City
A Level 0, classmate and friend of Uiharu. She wears a flower on the left side of her hair. She is cheerful and friendly, and is a little shameless as she sometimes flips Uiharu's skirt in public. She first appears in the Toaru Kagaku no Railgun manga and its anime series and makes a cameo appearance in the Toaru Majutsu no Index light novel series and the opening of the anime. Saten Ruiko is a girl with blue eyes and long black hair with a small, white flower on the left side of her hair. She also prefers wearing medium-sized skirts instead of short ones. The Toaru Kagaku no Railgun booklets bundled with Blu-ray and DVD releases lists her height as 160 cm. However, Yumiya Rakko estimated her height to be 150 cm. It is unknown whether Rakko's estimates were completely accurate. She has an outgoing and friendly personality, but is a little shameless as she sometimes flips Kazari's (and only her's) skirt in public. At first, she displayed apathy towards being a Level 0 but then became envious of the abilities of her friends as she was unable to fulfill her dreams as an esper. Due to this, she used the Level Upper. Later on, she grows to accept herself and becomes determined to develop her own abilities. Like her friend Kazari, she also has a deep sense of friendship; she was instrumental in helping Kazari and Kuroko make amends and made Mikoto realize that she has friends who she can count on. She is also adept at reading the atmosphere, and often changes the topic when someone is feeling uncomfortable about something. She is superstitious despite being in the city of science, though she likes to presume otherwise as when she states that she doesn't believe that her mother's good luck charm actually works.[3] Because of this, she is a fan of internet rumors and urban legends, and loves telling her friends about them. This extends to herself, believing that her nose is sensitive to money, though she backs this up by showing Mikoto four bank cards she had already obtained.[4] She has a natural tendency to be nosy regarding this, and often gets herself into trouble because of it, often needing to be saved by coincidental events or having become involved in events. Saten Ruiko can be described as a normal-acting preteen in the series in comparison to her peers, not having any extracurricular activities like Judgment or being particularly book smart. She is very affable, quick to make friends, and cheerful. She knows the latest trends and fashions, and in fact has the most wardrobe changes in the series. Description Provided By Gandeloft

A Certain Scientific Railgun
The student-filled Academy City is at the forefront of scientific advancement and home to the esper development program. The seven "Level 5" espers are the most powerful in Academy City, and ranked third among them is middle schooler Mikoto Misaka, an electricity manipulator known as "The Railgun." When strange incidents begin occurring throughout the city, she finds each crime to be connected to the elusive "Level Upper," a legendary device that allegedly increases the esper level of its user. As the situation escalates, it becomes apparent that there is more to the Level Upper than meets the eye, and that Academy City may be a far more twisted place than the glamorous utopia it appears to be. Toaru Kagaku no Railgun focuses on Mikoto and her friends—and the dangerous situations they find themselves in—as they get caught up in the matter of the Level Upper. As Mikoto says, "There's never a dull moment in this city."
