Toaru Jihanki no Sonzai Shoumei
She is first seen looking for level 5's to challenge. However, as a member of Judgment, she is unable to attack anyone without just cause, she later finds Misaka Mikoto kicking a certain vending machine and uses this as an excuse to fight her. Using her abilities, she uses Mikoto's AIM field as so she can discharge electricity. This does not go unnoticed by Shirai Kuroko and Sogiita Gunha - both members of Judgment, who were nearby and was forced to investigate.

When Gunha arrives, Nayuta rallies him to her cause and actually appeals to Kuroko's nature as a member of Judgment. With that, Gunha fights Mikoto; both of them however, show no hint of animosity and are happily testing each other's mettle. The fight is cut short when the Tokiwadai Dorm Supervisor arrives and takes Nayuta home.

Ability
She has the ability to manipulate other's AIM diffusion fields. She was able to make Mikoto discharge electricity that was enough to be noticed by Kuroko and Gunha.
