A/N: So, All For One doesn't have an available successor since his original choice, Tenko, didn't snap and murder his entire family with his Quirk since Nao left. But would you look at that, who should we find but a tortured, angsty teenage Touya Todoroki who was presumed dead not too long ago. Perfect supervillain successor material! Anyway, on to general villainous machinations and plotting.

Dabi watched the playback of the UA entrance exam with intent, keeping careful eye on the fellow teen who was apparently supposed to have been the original leader of his League of Villains. And wasn't that something? His League. Yes, technically it was commanded by All For One, but Dabi's ancient mentor saw fit to leave the actual command to Dabi. For of course, he'd never once had anything of his own, except for his flames. And even that was questionable at times. He'd always known he was something of a disappointment to Endeavor, even before Shoto was born, himself having been born premature and without any kind of counterbalance for his ludicrous heat. But now he owned that. Cremation had become not just his Quirk, not just his favorite pastime, but his very identity. And damned if he would leave a rival who was just as capable of leaving his foes as nothing but ashes and dust.

And so he watched, trying to find any limitation at all for the black-haired wunderkind with the touch of death, but aside from the fact it needed touch, he found nothing. Figures, he thought. I suppose that's why Sensei wanted him as the leader. However, the thought of a Quirk having no weaknesses unsettled Dabi greatly considering his own Quirk had such a notable one that it was allowed his current identity to even exist, so he decided it was high time he got more information.

Now, getting into UA the first time had actually been almost laughably easy; all he'd needed was a suitable distraction. And ravenous reporters chasing rumors of All Might teaching had certainly given him that opening. But the principal would be smart enough to see any more reporter storms all the way from across the Sea of Japan, so that was a no-go.

As the scarred teen sat on the couch in thought, his mind eventually drifted to his siblings, and oh how he hated that word. However, one thing eventually did cross his mind: Even though only Shoto had been trained to use his Quirk properly, Endeavor would be damned if any of his children didn't attend his alma mater. Indeed, Fuyumi was just starting her third year as a General Studies student, and so a plan suddenly came to him: 'convince' Fuyumi to get some info out of the young upstart Tenko Shimura. Of course, the exact details of the plan needed work, since it was hard enough getting Hero or Support Course students to talk to anyone not in either, but add in the age gap and it would be even worse, but Dabi had all year to hash out the details. Besides, he'd learned from that ill-fated day on Sekoto Peak that improper preparation and impatience could absolutely shatter any plan.

While he considered his new idea, he realized All For One was attempting to contact him. "Alright, Sensei, what exactly is it that you want?" he said even as he changed the screen.

"Ah, Dabi, good to see you," said All For One in his charismatic tone. "How goes the information gathering? I don't appreciate lost opportunities, but I am sure you've found a way to rectify the issue?"

Dabi nodded. "Fuyumi Todoroki currently attends UA's general course, she is in class 3-C. Given proper 'motivation,'" he added with air quotes, "I believe she'll serve as our UA informant."

All For One considered this. "Would it not be simpler to use a hero course student? General course students tend not to interact with hero or support course students, especially not between upper and lower classes."

"Yeah, that was something I figured might be an issue," Dabi replied. "Luckily, Twice here has offered a solution, as he'll explain now."

"What the hell!? No I didn't!" Twice blurted out. "Thanks for letting me do this, boss!"

"Get on with it," Dabi ordered.

"Alright, so basically my doubles don't just have to be of me, they can be any random loser off the street," Twice explained. "Including me, but whatever. Anyway I was thinking – and this is a stupid plan, for the record – I pick a hero course kid from UA and, well, double 'em up. If that sounds like a shit plan, it is, but it's what I got."

The ancient villain tapped his face mask, thinking. "Given your abilities, I'd say this plan is rather effective. But which student did you have in mind?"

The split personality shrugged. "Didn't think that far yet – wait no I totally did, it's one of the 1-A punks."

"I see," noted All For One. "Would it be Tenko?"

Dabi shook his head. "We all agreed that'd be stupid since the guy's already got a bit of a posse going and if Twice's double seems off, that'd tip them off too quick."

"So, one of the more… aloof students then." All For One finished.

"Exactly," replied Dabi. "Alright Twice, get on with it. I'm thinking we do our big announcement at some national event or whatever, and the UA Sports Festival's in a month."

"Alright, alright, on it, boss," Twice said. "Screw you, by the way, Scarface."

Dabi rolled his eyes. "Real funny from discount Deadpool over here. Now come on."

All For One turned to Dabi. "Am I given to understand that interactions are always this… sarcastic?"

"I think it's funny, personally," replied the burned man. "We're done here, correct?"

"Oh, certainly," replied the former master of evil. "I look forward to seeing how this pans out."

With that, the screen blinked off, and Dabi handed Twice a folder with all the students of 1-A. After about 10 minutes of shouting with himself, he landed on a particular student, then set about making the double. Mr. Compress then offered to ship that double off to UA himself, but Dabi realized they had an even better option: given they were coercing Fuyumi anyway, they might as well get her to, say, have a little… parting gift, as it were.

The girl in question was on her way home from UA, feeling rather worried given the… tense situation within her household. She had noticed the odd gazes her mother seemed to give to Shoto, subtle angry glares that the woman would never level at her father. As she came within a few blocks of the very traditional house, however, she received a very cryptic text:

"You are likely nearly home. Do not enter until after 6:00 PM. There is business I must attend to."

Fuyumi stared at the message, sent by her father. Business? It's not hero work, he wouldn't message me if that were the case… still, she obeyed the order, not wanting to face the wrath of the Flame Hero one bit. Sighing, she figured it would be good to meet up with one of her friends, and so after sending a quick text, she began walking toward her closest friend's house.

Mr. Compress smirked, realizing that their chosen target would no longer be in a secure location when she didn't show up at the Todoroki household's front door. He sent a brief message to Dabi, then moved to intercept Fuyumi.

Dabi, of course, was pleased at the news. "Just my luck that someone in that hellish household snapped. Compress, how close are you?"

"I'd wager only a few blocks," replied the magician. "I'll have the girl with you within 15 minutes. Have Kurogiri on standby, would you?"

Sure enough, as Fuyumi strolled through the streets of her neighborhood, she suddenly found herself face-to-face with the masked magician. "Can I help you?" she asked.

"Oh, certainly, miss," replied Mr. Compress. "My wallet slipped out of my pocket earlier and my hands are too large to fit into the crack it slipped into. Your fingers, however, should be perfect. And might I say they look positively lovely today?"

Fuyumi blushed, but nodded, reaching down into the crack where she could see the wallet just barely poking out of. She pulled on it, but it didn't budge. "Sorry, my grip strength isn't great…"

"Oh, no, it's perfectly alright!" said the magician. "I don't have anywhere particular I need to be right now… you, on the other hand?"

Fuyumi turned back, confused at Mr. Compress's wording. "What do you mean by-MMPH!"

At that moment the performer's hand covered Fuyumi's mouth, and with a bright flash, where once stood a high school third year, there was now merely a small blue marble. Grabbing his wallet, he inspected the marble containing Fuyumi.

"Terribly sorry about that, miss," said Mr. Compress, staring at Fuyumi's image inside the marble. "Don't you worry, you'll be perfectly safe with me." Taking out his phone, he then called Kurogiri. "Ah, Kurogiri? Yes, if you wouldn't mind conjuring a gate for me." A pause. "Yes, the girl's with me. Charming young lass, I must say, you'd like her." Then a purple void appeared next to him. "Stepping through now, my good man. Your service is exemplary."

As Mr. Compress made his way through the portal, it closed behind him, and he glanced around at the familiar bar the League had been using as their base of operations. "Well, I have returned!" he said, before heading up to Dabi's room.

Stepping into the somewhat small room, he pulled out Fuyumi's marble, and let it decompress. The girl stumbled forward slightly, before standing up and noticing she was not somewhere she recognized. At all. She held back a scream, but at that moment Dabi, dramatic as ever, stepped out of the shadows. "Hey there, lady. Name's Dabi. How about we make a deal?"

At that moment, Fuyumi screamed. Or, well, tried to, but then the gloved hand of Mr. Compress very quickly muffled that. After getting the shock out of her system, she glared at Dabi, mustering up as much of the Todoroki intimidation factor as she could reasonably manage.

Dabi, however, remained unimpressed. "Fuyumi Todoroki, right? Look, my flames burn hotter than your deadbeat of a dad, and if you'll note the scars… I don't care about heat too much. So why don't we sit down and have a civilized discussion and you can head right back where you were going."

"And why should I listen to some edgelord who couldn't even be bothered to do his own dirty work?" Fuyumi asked.

"Check the hair," said Dabi, before he sat down and leaned forward slightly.

Fuyumi did so, and rolled her eyes. "So it's dyed. More points in the edgelord category. Naturally white, it would seem… wait… turquoise eyes, white hair, major burn scarring…" At that moment the realization hit her. "T-Touya!?"

"Hey there, sis," Dabi deadpanned, even as a smirk began to form. "Also don't call me that."

"I-we thought you died!" Fuyumi shouted. "We found your charred jawbone up on that mountain!"

"Yeah, and what about the rest of me?" Dabi countered.

"Well… In any case even if you are Touya, or were, maybe, which I don't really believe…" Fuyumi said, "Why would that make me want to trust you? You clearly don't want the secret out, so you'll probably kill me now, won't you."

"Oh please, if I wanted you dead I would've done it already," Dabi scoffed. "Or I would've let magic man over there make you his 'assistant,' and then killed you. Nah, what I need is info."

"Info on what? The Todorokis?" Fuyumi asked.

"No, I just need some details about a UA kid. Tenko Shimura, class 1-A."

"If you hadn't remembered, I'm a third year, not a first year, and I'm in general studies."

"…Which means it would be really bad if, say, this conversation leaked out."

"And what would stop me from reporting you the moment I leave?"

"You think anyone's gonna believe that a generic high school girl, even the daughter of the 'great and powerful' Endeavor, somehow found the League of Villains hideout on her own?"

"There was also the kidnapping, so…"

"Which you don't know how it happened," retorted Dabi. "No evidence on your end, they're not gonna believe you. And how bad would that be for Endeavor, huh? I mean, his otherwise well-meaning, nice daughter suddenly finds the hideout for an unrevealed League of Villains? You'd get locked up, probably interrogated by people less lenient than I am, and dear old dad would be completely out of a job. Sorry about mom, by the way."

"Wait wha-" Fuyumi stopped, then sighed. "Alright, fine. What do you need me to do?"

Dabi rattled off the list. "UA Sports Festival's in a month. I want all the data on that Shimura kid's Quirk you can find or get from the horse's mouth. Daily info packets, texted to this number-" he handed her a Post-It, "Oh, and I always liked that Mapo tofu you learned how to make. Make me a batch at least once a week, I'll get Kurogiri to pick it up."

"Is that all?" Fuyumi asked.

Dabi shook his head, letting a small blue flame trickle from his finger. "Any screwups and I'll burn you. Any major screwups and these contacts get leaked. Clear?"

"Crystal." Fuyumi said. "Now, may I go?"

"Yeah, you're free to leave," Dabi said, motioning to the door.

"Well, miss, I'm afraid you'll be a little more confused now," Mr. Compress added, and as Fuyumi turned back she once again disappeared into a blue marble.

After Kurogiri dropped them off a few blocks from the Todoroki household, Fuyumi reappeared, only this time she found herself walking into Mr. Compress. "You haven't given me an address or anything, you really don't need to do that every time," she groaned.

"Ah, apologies," Mr. Compress said. "It's just that… your confused face… pleases me."

Fuyumi gagged. "I'm a minor, and you're, what, 25? Drop the gentleman act already."

"Fine then. Go on, now, your family awaits you." Mr. Compress said.

Fuyumi sighed as she walked back to her house, only for a police car and ambulance to drive away from the front steps. Peering inside the car, her eyes bulged. Mom!? As she crossed the street, she saw a note posted on the front door:

I will be handling an important family affair in the next few days. Shoto has been injured and Rei is responsible. If anything at all out-of-line occurs, all of you will be without a home.

-Endeavor.

Fuyumi gulped. Just my luck that I have a double life now, too…

A/N: Well, Fuyumi's an informant and we have a UA traitor! Oh, and canonical Todoroki issues are occurring, if you couldn't quite tell. In any case, the next parts of this arc are going to be one intrigue-filled ride, all the way up until the Sports Festival. Oh, and of course there'll be plenty of new and exciting events then, too.

Also, Quirk Profile Time!

Namiutsu Ishi, Quirk: Aggregate!

He can pile up loose chunks of dirt, rock, or other material around his hands to form makeshift maces or gloves! He can even launch his piles in the same way one might throw a baseball! As of right now he can't form anything larger than a half-meter radius sphere on either hand, though.
