Saten Ruiko

Age: 12-13

Ruiko is a character from the Toaru Kagaku no Railgun sidestories. She is a Level 0 Academy City student and a classmate and close friend of Uiharu Kaizari. Ruiko has an outgoing and friendly personality, but is a little shameless as she sometimes flips Kazari's (and only her's) skirt in public. She was born outside Academy City and when she was younger, she decided that she wanted to go to Academy City to become an esper.

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. 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.

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.
