"Ah, this one sure is interesting Doc."
"They have an interesting quirk. Let's try this one out."
There was a bright light overhead, it was hard to see anything else in the dark room. A child was strapped to some sort of exam table. They struggled against their restraints, prompting a chuckle from one of the two figures looming over them. The words they spoke made no sense to the child, nor did the entire situation. Try as they might, the memories leading up to these events did not come to mind. Just like the restraints holding them down refused to give. One of the figures, the much smaller one, began fiddling with some machines.
"[Lemme go!]"
"Oh, Kumori, you needn't struggle so," the larger figure spoke in what was likely meant to be kind. There was something menacing about it though, as he reached out toward the child's head. The last thing she remembered was feeling a hand rest against her head, then a searing pain throughout her body. She screamed and writhed against her restraints, to no avail.
"Oh! See, what an interesting result!"
"Quite proud of yourself, aren't you," the two figures chatted calmly while watching the scene before them. The child's small frame put up a strong fight, wracked with pain. The equipment monitoring their vitals showed them going crazy, then settling down when they lost consciousness. The scales that covered their body had begun to shift and pull away. Some came off, but most remained. Previous tests had shown that they were impervious to damage from disintegration-type quirks, so a different route was being studied now. Scales that had separated from the earlier experiments, stored nearby, had reacted as well to the newly added quirk. They gathered around the child before falling to the floor.

"And don't forget, next week we'll start preparation for the UA Sports Festival. Class dismissed."
"Hm?"
Senji snapped awake, just in time to receive a glare from her homeroom teacher. She quickly scooped her notebook and supplies into her bag, rising from her seat with the other students. She quickly shuffled out of the room and into the crowd of students gathering in the hallway. Senji was deeply lost in thought, trying to shake the feeling of her weird dream. No, flashback? She shook her head, pulling herself back to her senses. It was just then that she noticed the crowded halls were much more cramped than usual with students.
"[What the-?]"
"Watch it! Huh?"
Students were shouting now, and all rushing to the windows to see what was up or panicking. An alarm was blaring, but the raucous of the students easily drowned it out. Senji was bumped around and pushed into a wall hard. The impact grated against the scars she had, making her flinch.
"Ow, shit."
"Damn extras, the fuck is this?"
"Ah, of course," Senji groaned. The body currently rammed into her was Bakugo, though it took him a moment to realize. The two shared a look of extreme discomfort before cursing under their breath. The situation was getting more and more intense, but someone shouting at the end of the hall dispersed the intense stress in an instant. As the students dispersed, Senji let out a sigh of relief.
"Ice? Whatever," Bakugo grumbled and wandered off.
"Huh?"
Senji looked around, but didn't see anyone using an ice quirk. She felt something itchy on her arms, and looked down.
"Ah, oops."
Her quirk had started manifesting due to stress, covering her body at any point of impact during the shuffle. She shook her head again, another habit of hers for literally shaking off her anxiety. Taking a deep breath, she collected herself and headed for the exit. She had work, then a meeting of sorts, then studying. Her schedule was packed full all the time now. The weather was getting warmer, too. That made it hard to move around too much during the day and wore her out. The sports festival also meant Senji would be busy with Recovery Girl.
"Please hold back at least a little," she whined as she neared the Midoriyas' apartment. After a quick change of clothes, it was off to stop two of the day: the Bakugos' place. Senji worked through the few hours, and ended up getting pulled into a meeting of some kind with Mitsuki. The details went over her head in the moment, but it seemed like some other kind of side gig came up. She had scribbled down some notes for later, at least. The weather was turning when she left there, looking like a rain storm was rolling in.
She walked absent-mindedly for a good while. The rain started light, but quickly picked up, soaking through her clothes. Hope I don't get a cold. This is nice, though. Senji opened an old door in a dingy alley. Inside was a now very familiar scene, of a cozy little bar. There were less people gathered around today.
"You're late," the white-haired "boss" nagged. "And after ignoring us for so long, too. Rude."
"My bad. Been busy."
"Can't you fly or whatever? Should be faster than that," this remark came from the dark haired man, Dabi.
"Rain weighs things down. Anyway, I'm here now."
"Got some good intel, I hope."
"Yeah, yeah. Some beef, too."
"USJ? We went all out, but most of your little classmates weren't hurt. That's a good outcome isn't it."
"Shiggy, you know that's not what I mean here. You were after All Might, right? Wasn't a need to bash up anyone else," Senji addressed the boss casually. Her tone seemed nonchalant, but she was angry about some of the details of that event.
"Hm? Don't tell me you were worried abou-Oh. Eraserhead?"
"Tch," Senji let her face slip a little there.
"Right. Your last name's the same. Guess you're connected to him. He's really cool, could see why you'd look up to him."
"That's not..whatever," Senji was ready to change the subject. "You wanted info, right? The sports festival's soon, it's televised. I think there's some potential firepower you could gain from there. Watch it."
