Harumi Kiyama
A scientist employed within Academy City. She has poor common sense, which is demonstrated as she often strips in front of others without thinking about it, a result of her years being a researcher.
She is revealed to be the creator of the Level Upper, which functions as a network to connect the minds of espers who use it. This is also revealed to be the source of her powers, because as the administrator of the Level Upper, she is able to access and control the powers of all the psychics linked to the network.
She made it to complete her research about ND-rays, which she needed to finish to save children who became victims of an experiment, in which she herself took part in.
