Kobayashi Satori

Kobayashi Satori is a minor character in Toaru Kagaku no Railgun. She is a third-year student in Tokiwadai Middle School and is a Level 3 esper whose power involves telepathy. She is a member of Shokuhou Misaki's Clique, and is a leader of sorts among her fellow clique members second only to Hokaze Junko.

Appearance
Satori is a young girl with an appearance befitting that of a normal middle school girl. She has short hair with straight bangs.

Personality
Her personality is described as "leader-quality". She has a certain wily attitude despite her calm face, as she used her powers to keep an eye on Mikoto. She is scared of bugs, especially spiders. In spite of this, she recognizes other people's leadership qualities as well, as seen when she notes that Hokaze Junko is now the center of the clique after Misaki's abduction by Yumiya Iruka, encouraging her to take command and following her orders.

Daihasei Festival Arc
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 on Misaka Mikoto using her powers.

Dream Ranker Arc
She appears in an Indian Poker card that Misaka Mikoto was using while searching for the Bust Upper card.

Astral Buddy Arc
During efforts to rescue Yuuri Senya and stop the out-of-control individuals connected to Ideal, Shokuhou decided not to utilize her clique as members had been using Indian Poker and might have seen the Ideal card, and subsequently be susceptible to its influence.. A depiction of Kobayashi's face, along with Asato and the glasses girl's faces as well as an apology from one of them, during an explanation to that effect suggests she might have been among the ones who had used Indian Poker.

Toaru Majutsu no Virtual-On: Misaka Mikoto's Dangerous Tea Party
She appears alongside Hokaze Junko and the other girls of Misaki's clique. They are ordered by Misaki not to interfere with her talk with Misaka Mikoto in the Rude Café, a café where the guests can go wild and use the food and objects there to smash and attack each other harmlessly even the employees. This creates misunderstandings within the clique as Satori uses her powers to spy on Misaki and Mikoto. Scared of what Mikoto is doing to their Queen, Junko goes inside without the Queen's permission and is punished for it by Misaki shoving a cake on Junko's butt. She later warns Satori through Junko who is connected via telepathy, much to her horror.

Abilities
Her telepathic ability is similar to the one that appeared in Toaru Majutsu no Index Volume 6, using a "circuit" that is apparently an extension of her AIM diffusion field, Satori 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.
