Given that Tokyo is a major population center of Japan, it was not statistically unlikely that multiple students in their class would be from Tokyo. In fact, it would be improbable if none of the students were from Tokyo. Of course, it would make more sense to have applied for UA, but Gendou hadn't even considered any other school; Ishin was his mother's alma mater, and she was his goal and inspiration.Gendou focused on these pointless thoughts in order to distract himself from what was clearly happening around him. Being surrounded by three girls, his heart raced, but not for the reason one might assume of a teenage boy. This was, unfortunately, a tactic he had seen all too often. A group of mean-spirited friends singles out someone to pick on. They approach, one at a time, pretending not to know each other, taking their time to size up their victim; see if he's an easy target. Eventually, they will surround their victim, preventing escape, and make their intentions known, spoken in hushed tones so no one outside the circle catches on. They were going to make him their slave for the rest of the school year, if not longer.
Yoshiba asked if he was nervous, which was clearly a way of letting him know that she smelled his fear. Touko's overly friendly, "My people", was a way to force closeness and blackmail using arbitrary 'connection'. Talking about other people being annoying or problematic was supposed to create a false security, a poor effort to convince Gendou that these three were the only ones he could trust. And Kokone answering Yoshiba's 'nervousness' question robbed Gendou of any agency in the matter. In just a few simple steps, they had established complete control, and he had let himself fall into the same trap again.
Gendou wanted to vomit.
He didn't know what to do. If tried to run now, they'll know they got to him, and how easy it is for him to break. He'd give them what they wanted, information that he was easy to bully. But what if he played along? He knew his acquiescent nature would come through, and the result would be the same. They'd know that whatever he was doing would be an attempt to appease the situation. of course, calling for help or simply sitting there stunned would all mean the same thing. He could try to
fight his way out, but that could result in failure, or get him kicked out of Ishin altogether. What kind of hero-aspirant attacks his classmates before the opening ceremony?
"I'm from Meguro Ward," Gendou's delayed conversation brain causes him to blurt out the thoughts that he was trying to distract himself with. Given that several of them are from Tokyo, it only made sense to get a little more specific. Gendou covers his mouth with his hands, afraid that he'd draw the girls' ire for speaking out of turn.
"S-sorry," Gendou was quick to apologize. Though the smart thing to do would have been just to keep quiet and gauge their reaction, Gendou suddenly felt that he had to do something, anything to take back an iota of control.
"I-I g-guess I am pretty nervous. This was my mother's school, and I just want to make her proud, you know?"Gendou was spiraling and beginning to divulge too much information. Now they knew he was a momma's boy. But as long as he didn't reveal his quirk and give them the opportunity to judge how disgusting it was and get the idea of harming him through his eyeballs, he'd be fine, right? But right now, all he could think of was his quirk and how they'd react if they saw it, so he glanced at them, trying to ascertain what their quirks were. For Kokone and Touko, it wasn't so obvious, but for Yoshiba, he had a guess.
"D-do you have prehensile hair?" Gendou asked, trying to divert attention away from himself,
"That's pretty cool."Gendou chided himself; what a dumb way to compliment someone's quirk.
