All Might tried to excuse himself quickly, probably to talk to his successor about making a big entrance at the sports festival, but Shouto insisted it was important and he relented. We were led to the teacher's lounge, which was empty. My hands felt a little sweaty so I wiped them on my skirt nervously. It was awkwardly quiet for a minute as we sat across from each other. Eventually, my twin must have got tired of my stalling and nudged me. I looked at him with panicked eyes. What exactly was I supposed to say?! It wasn't like with him. I didn't have the benefit of years of evidence piling up in my favor for such a ridiculous claim.

"Todoroki-shoujo, Todoroki-shounen, is something the matter? As your teacher, I will do my best to help you, whatever it may be."

Shouto took pity on me and broached the topic for me. "Hien knows the future."

Both All Might and I choked in surprise at the bold declaration. Well, no one ever said Todoroki Shouto ever hesitated when he had his mind set on something.

"Hahaha, a funny joke, Todoroki-kun, but I'm well aware Todoroki-chan's quirk isn't clairvoyance."

I shifted nervously and took a steadying breath. "Your name is Yagi Toshinori." I ignored the explosion of blood from his mouth and my twin's startled noise. "Your quirk is called One for All. It's a stockpiling quirk that exponentially increases in strength the more it is passed on. You inherited it from your predecessor, Shimura Nana, the seventh One for All holder. It originated when a man called All for-"

"Todoroki-shoujo!" All Might's mouth was dripping with blood as he frantically waved his arms, trying to stop me from revealing anything else. It was probably only his immense self-control that kept him from "popping" and revealing his skinny form.

"How do you know all this?!"

I raised a brow as if the answer was obvious. "Like Sho said, I know the future. You told- will tell- someone else this so I already know about it. I can keep going if you don't believe me."

"No, no, no, no. That's alright. I believe you." He glanced around the room as if he was afraid that someone had overheard me. "How did you come to know this information exactly?"

I shrugged helplessly. Shouto had agreed that I should keep the exact details of my rebirth quiet. Like I'd said before, it wasn't anyone's business but my own what my life was before.

"I've always known certain things I shouldn't, ever since I was born. I wanted to warn you about some events that I wanted to prevent happening in the future. The easiest way was to tell you first. We were hoping you could help us convince the principal. I...can't change anything on my own. I'm just a student. But you, sir, you can act in ways I can't, minimize or prevent the damage altogether."

My fists clenched in my skirt and I stared unflinchingly at his bright blue eyes, and we held the gaze as he assessed me.

"I see. Very well, Todoroki-shoujo. I assume by future events, you're referring to the League of Villains?"

I nodded, confirming his suspicions.

"Then perhaps we should bring the principal into this conversation. Wait here, I will retrieve him." He stood, clearly troubled by what I knew, but All Might will always be All Might, so before he opened the door, he turned back to look at us. "Thank you for coming forward with this, Todoroki-chan. It was very brave of you. I'm sure you were very worried, but fear not, for I am here."

A fond smile came to my lips unbidden. Trust the number one hero to put aside his own worries to comfort a distressed student. I gave a grateful nod and he quickly left to find Principal Nedzu. I slumped over on my brother and he patted my head.

"Good job."

I grunted something that was meant to resemble a thanks and buried my face in his shoulder.

"Is that really what his name and quirk are?"

I snorted but hummed in confirmation. "He doesn't actually look like that either. His quirk allows him to beef up, but thanks to an injury he received, his natural form is a lot thinner and weaker. That's also why he was coughing up blood."

I saw the puzzled expression on his face and I knew he was trying to picture a skinny All Might when he only knows the strong, muscled version of him. I couldn't help myself; I smooshed his adorable cheeks, much to his exasperation and resignation. He was too used to such things from me to bother with more than a token protest.

It was to this sight that All Might and Principal Nedzu returned to. Despite the seriousness of the ensuing conversation, they found themselves chuckling at the antics of two young kids. Our pale cheeks flushed, embarrassed about being caught acting like anything less than the mature, heroes-in-training that we portrayed ourselves to be. With a cough, I separated from my twin, nervousness returning.

"Todoroki-chan, All Might has told me of your unusual precognitive abilities. I am here to assess the truthfulness of your claims and then move forward with any information you can give us, provided that it proves to be reliable."

I could feel Shouto bristle at the implication that I was a possible liar and unreliable, but I just nodded.

"It's not an ability per se. I just have knowledge of future events up to a point and if anything happens to change that future, then 90% of my knowledge will be useless. It doesn't really come from anywhere, I've just always known things."

"Well, I'm already aware you have extensive knowledge concerning All Might that you couldn't possibly know otherwise. What else can you tell me?"

"I can't tell you anything personal about yourself if that's what you're asking. The only reason I know so much about All Might is that he and his successor are center stage for all the big events in the future."

"Ah, so is it safe to assume that you know a great deal of personal information about his successor as well?"

"Yes, and All Might, sir, I have some advice for him that could help him master One for All easier. I know he's having a hard time with it and if he keeps using his power recklessly, there's a chance he could damage his body irreparably."

All Might paled considerably. He was aware of the dangers of One for All but perhaps he'd believed Midoriya would learn to control before it got to that point.

"I don't mind letting him know about me if you wish to tell him. I think it could do him some good, having someone his age who he can share the burden of such a big secret. Another person I think would be a good idea to bring in is Aizawa-sensei. You need someone who will be 'out in the field' so to speak, who can act on my foreknowledge when you're not available. Other than that, it would be best to keep the circle small. The fewer people that know, the less danger there is of anything slipping."

The principal nodded, agreeing with his typical friendly demeanor. "Yes, yes, those are all excellent ideas, young miss, and ones we will take into consideration. Now, what can you tell us about the League of Villains? What are their goals? Who is their leader? Other prominent members?"

I let out a breath as I drew upon every bit of info I crammed last night about the League. "Their leader is the man called All for One."

"What?! That's not possible."

All Might launched to his feet. I smiled sadly at him knowing how devastated the news must make him.

"He survived, just like you did, sensei."

"Troubling news indeed, Toshinori, but we really must hear what else she has to say."

"Right, forgive my outburst."

All Might sat down again, calmer but no less upset about All for One's survival.

"He's taken in a protege, much like yourself, by the name of Shigaraki Tomura, although that's an alias. His true identity is another upsetting revelation for you, All Might-sensei, so I'll leave it till the end. His quirk is Decay and he can decay anything as long as all five of his fingers touch it. I'm unsure if the loss of a finger would nullify his quirk. Another notable member includes Kurogiri, the warp quirk villain. There are others, but as of now, they are yet to join the group, and although I could give you their villain names and quirks, they will only join after the hero-killer Stain is caught.

"Which reminds me, he'll be in Hosu city soon if he's not there already. One of his victims will be Ingenium. He'll live but the damage leaves him paralyzed, forcing his retirement. It will happen during the sports festival.

"The League won't make a move during the festival because of their drastically reduced numbers and the injuries Shigaraki sustained at the USJ. They won't appear again until the summer training camp. Because of this incident, it's suspected that there is a possible mole in the school, so in order to find the leak, the dorm system will be implemented. During camp, one of the students will be taken, and thanks to the ingenuity of another student, the League's hideout is discovered. This leads to a confrontation between yourself and All for One, which causes you to use up the last of One for All and your identity to be revealed to the public. You obviously retire from hero work to continue teaching and focus on training your protege. Shortly after that, the Provisional License Exams take place. Afterward, some serious trouble involving the yakuza, I believe it was, and human experimentation on a young girl happens, but unfortunately, I couldn't tell you anything useful about that other than that the girl's name is Eri and that her quirk allows her to...reset a person's body, I think?...to a previous state. The yakuza use her quirk to create some sort of drug that renders people quirkless, but I believe it can wear off eventually. Although, I might be mistaken about that."

Principal Nedzu and All Might share a hard look. The rise in and severity of villain activity to come no doubt worrying them immensely. Shouto squeezes my hand. Even he's concerned about the danger that we'll likely be dragged into.

"Yes, the boarding system sounds like something we would do. I've been contemplating such a thing for a while. An attack on our students would be just the push I'd need to see it through." He hummed thoughtfully. I imagine he was analyzing all the information and devising a course of action to take with his superior intelligence. "We need to call a meeting. We have much to discuss and plans of our own to begin implementing, but for now, I believe I'll get started on those dorm plans just to have them prepared, and you two, lunch is almost over. You should get some nourishment for yourselves. You'll be called when we meet to discuss our next move."

We nodded, and I relaxed now that the conversation was coming to a close. I actually made it through all that.

"Ah, Todoroki-shoujo, you mentioned I needed to know the true identity of Shigaraki Tomura. I'm not sure how it relates to me personally, but I trust you if you say it's important."

Spoke too soon. I winced, having forgotten about that detail. "Yes, that. Um, perhaps it would be a good idea to get in touch with Gran Torino. Not tell him everything, but this part is sort of related to him, too. He deserves to know and you should really talk to someone who would understand. Plus, you need someone to rein you in sometimes, sensei, no offense." I cut myself off when I realized I was stalling. "Right, uh, well, Shigaraki Tomura's real name is actually... Shimura Tenko, the grandson of Shimura Nana."

Idk what it is lately, but I'm more in a writing mood, which, good for you guys I guess lol. We're getting to the bigger canon divergence stuff now. Quick question, romance isn't a big plot point, but I would like to sprinkle a bit here and there like the series does. So is there anyone you guys would like to see Hien interacting with? Please note that just because she has a romantic scene with someone doesn't mean they're endgame. I want to leave that up in the air since, you know, they're all teenagers, and they're not exactly known for long-term commitment and true everlasting love. There might be a serious relationship later down the line, but not until after the provisional license exam and maybe the internship arc. It depends on where exactly season 3 ends. I've decided to use that as the cutoff point for most of Hien's knowledge. Anything after that is just vague spoilers she remembers. Like she knows about Eri and what her quirk does and that she was used to produce that quirk erasing drug, but nothing else useful.
