She is a girl with an average looking build, although she would prove to be stronger than she looks when subduing a hired thug later on. Her most prominent features are her unkempt hair and her wide open eyes, dubbed “fish-eyes” by Misaka Mikoto. She seems to adhere to gothic lolita clothes, when she is not wearing her uniform or lab coat. Not much is known about her, though she seems to exude an air of aloofness. She is calm, as shown during an attack by a group of Outs.
