Kiyama Harumi

Kiyama Harumi (木山 春生, Kiyama Harumi?) (born August 9th) is a character in the Toaru Kagaku no Railgun side-stories. She is the primary antagonist of the first storyline and becomes a supporting character in the second storyline of the anime adaptation. She is the creator of the Level Upper, a sound which, when used, allowed the user's abilities to become stronger.

Most of her appearances depict her having long wavy brown hair (which was shorter a considerable amount of time before the start of the series) and her most striking feature: bags under her eyes (which is the result of intense research in trying to revive her students). She is often seen in a white long-sleeved shirt and a brown pencil skirt and always wears a long white coat which scientists usually wear inside the laboratory. Later appearances gave her a suit to wear instead. Harumi acts too logically and lacks common sense, which is demonstrated when she stripped in front of others without thinking about it, a result of her years being a researcher. In Toaru Kagaku no Railgun, she is revealed to be the source of one of three urban legends popularized by different Web forums within Academy City, the urban legend of the "Stripping Woman". She is shown to have low self-esteem about her body, justifying stripping in public by saying that no man would care about seeing her body.

Originally, having difficulty with children, her experiences after becoming a teacher to Child Errors. Although she is kind and considerate in people in general, she is fiercely loyal to her students, willing to make Academy City her enemy, make use of weak espers, as well as willingly cause destructive Poltergeist phenomena for their sake. In the last story arc of Railgun, she is seen to be usually downcast, putting herself to blame for what happened to her own students. She manages to take refuge to Misaka Mikoto's dedication to help others (and once noted that they share similar ideals) and Uiharu Kazari's eagerness to help her student Edasaki Banri.

The bags under her eyes are a direct consequence of Harumi's intense dedication to her work as a researcher and the lack of sleep
