Natsumi is described as a girl with a ponytail. During the heat wave, she wore a racing swimsuit like the other girls at Tokiwadai. At other times, she presumably wears the standard Tokiwadai uniform.
Natsumi appears to be somewhat sheltered and had apparently not touched a 'gentleman' in her life.

On December 10th, when Misaka Mikoto brought Kamijou Touma to School Garden, Natsumi was among the Tokiwadai girls who were curious about the 'gentleman' that Mikoto and Shokuhou Misaki were interested in. While Touma was walking down a hallway, Natsumi snuck up behind him and touched his back with her finger before speeding off to regroup with her friends.
As a student of Tokiwadai Middle School, Natsumi can be assumed to be an esper with a Level of 3 or 4, though her ability isn't known.
