A Certain Scientific Railgun
Daihasei Festival (Railgun)
- Main article: Daihasei Festival (Railgun)
She appears alongside her Tokiwadai sistren during the balloon hunting competition, using her telepathic abilities to communicate and delegate orders to her fellow Tokiwadai schoolmates. Her fear of spiders is later exploited due to efforts of Baba Yoshio, which sends chaos upon all those she used her telepathy on, making them sitting ducks. She is later eliminated from the competition. She reappears in the second day of the festival as an apparent member of Shokuhou Misaki's clique, here, she has been tasked to keep an eye of Misaka Mikoto using her powers.
Her telepathic ability is similar to the one that appeared in the 6th Index Light Novel Volume, using a "circuit" that is apparently an extension of her AIM dispersion field, Shimanaka is able to communicate with anyone she has connected to, and vice-versa. She is also able to connect to more than one person at a time. This connection allows her to find the general location of the person.
