To say Izuku was shocked when he saw the Symbol Of Peace himself standing before him was an understatement. Were it not for years of being trained to always be on guard just in case, Izuku surely would have frozen up then and there in shock.

"A-All Might?!" He asked in disbelief, getting the man to look his way. The muscular blonde looked… conflicted about something, though what it was Izuku had no idea.

"Ah, you must be the student principal Nezu was talking about!" The pro said with his usual smile and boisterous voice, though Izuku could read the subtle tells like his twitching fingers that whatever this was about was something worrying the man. He was hardly subtle, so it took almost no time for Izuku's trained eyes to pick it out. "Nice to meet you, young man. As you observed yourself already, It is I, All Might!"

There was a beat of silence, then every lesson on composure, defence, constant perception and observation and every other lesson ever instilled into him about how he should act all immediately left his brain as he quickly bowed, kicking into full fanboy mode. "Ah! It's so nice to meet you sir, I'm Izuku Midoriya and I'm one of your biggest fans! I know there's a lot of them but I mean it, you're such aninspirationtomeandIneverwouldofgottenwhereIamnowwithoutyouinspiringmeandisthereanychanceIcouldgetanautograph? ohnowaitthatsrudesorryIjustI'msoexcited!

"Izuku!" Nezu spoke up, with an amused twinkle in his eyes, while All Might looked like he had paled slightly at the sheer amount of words one boy could produce in the span of three seconds. His own dark eyes shot a concerned, confused glance Nezu's way. "Breathe. Perhaps I should have given you a bit more warning to prepare, but you need to remember to keep yourself under control."

"R-Right, yes sir! Sorry Nezu, s-sorry All Might." Izuku apologized sheepishly, rubbing the back of his head as he flushed at what he'd just done. Here he thought he'd been doing quite well at restricting his muttering to only while he was building and analysing as well.

"You're uh, sure you're sure about this?" All Might asked Nezu quietly with a confused voice, meant to be quiet but Izuku still heard. Nezu chuckled.

"Yes, this one is on me. Izuku is quite a big fan of yours, you should see his room-" "U-UNCLE NEZU!" "However, that has nothing to do at all with why I asked what I did. I merely wished to see Izuku's reaction were your new role was a surprise for my own amusement. I have much more valid reasons for asking what I have of you."

"H-Huh? You're asking All Might to do something regarding me?" Izuku asked, confused, raising a brow. The blonde coughed awkwardly. Nezu smiled with his usual twinkle, putting his paws together.

"Why yes, however we can get to that in a minute. First I would like to formally introduce you two. Please, be seated." The hybrid creature gestured at the two seats in front of his desk, which Izuku and All Might immediately sat down on, the younger student on the left and the older pro on the right. "Now then, Izuku, All Might here, you obviously know as a person, but he is also our new staff member as a U.A. teacher who will be teaching you first years. All Might, this is U.A.'s longest enrolled student and our star private student, Izuku Midoriya. He has been training in these halls for far longer than just this year, and when he finally graduates our course, he will be one of the most historic students to ever leave these halls, all of us here at U.A. are quite eager to see him succeed and leave as a true hero."

"Historic?" All Might inquired curious. "You must be one hell of a kid to be getting a private education and Nezu's approval like this. I must admit I am curious young man, what would make your graduation so historic?"

"I can handle this if you'd like, Midoriya." Nezu spoke up but Izuku shook his head with a sigh and a patient smile.

"Thanks but it's fine. All Might… I don't have a quirk." Izuku would deny he got some amusement out of the undignified confused noise halfway between a snort and some choking noise that escaped the muscular man at the reveal. "That's why I've been getting a private education for so long, and why If- No, when I graduate, it would be historic, because then I'd be the first official quirkless hero the world's ever seen."

"I… see." All Might said, before frowning as he processed this information. Finally, he spoke up, voicing his thoughts with a heavy sigh. "Forgive me, I do not wish to hurt anyone's feelings or try to imply any criticism of your judgement Nezu, but is allowing a quirkless person to be a hero really… safe?"

Nezu kept a close eye on Izuku but instead of hurt or worry flashing over Izuku's face, his patient smile held as he adjusted himself, the only real difference being his smile looking slightly more tired.

He always knew he'd have to deal with this, from just about anyone and he was patient. He could prepare for it, and as he told Tooru when she asked the same thing…. "Not at all. In reality though, it's not any more dangerous than any other hero in the field. I can cite a few examples, like Pointer Kid. He's still a hero but honestly, I would argue I could handle a villain attack better than he could. Not to be rude to him, it's a simple fact, I have taken several measures and classes to ensure I can keep up with everyone. This job will always be dangerous no matter who takes it on, and just because I don't have any natural powers doesn't mean I would be in more danger than anyone else."

All Might opened his mouth to that, before closing it, gripping the armrest of his chair as he mulled that over. The conflict was clear on his face; he wasn't convinced yet. Izuku sighed slightly but he still didn't let it phase him. "I suppose that makes sense, I just… it's an odd thing to hear."

"Well, you'll see for yourself soon enough. The only opening for teaching positions were the hero studies course and Lunch Rushes culinary arts course. I have seen the video of you trying to make a salad on that one talk show. " Izuku hums, and the number one pro goes beet red in memory. "So you'll definitely be seeing me in action soon enough." 'I'll just have to prove myself then.'

"I suppose so. Nezu seems to have faith in you so I suppose I am more just letting my own natural instincts to worry take over." All Might offered, before turning his attention to the principal who had been eyeing the whole conversation with a curious gaze. Now the spotlight was back on him however, he smiled and clapped his paws together.

"Wonderful, now that we're acquainted we can move on." Nezu smiles. Izuku nods.

"Sounds good, I doubt you'd bring me in just to meet a new member of staff if we were going to meet on our first week anyways." Izuku brings up, knowing there had to be more to this. The Mouse-Bear-thing that was Nezu hummed in acknowledgement. "So I assume this is to do with whatever you wanted him to do regarding me."

"Quite right. As I've already told him, what I wish for All Might to do… is tell you a secret of his." Nezu said simply, keeping it vague. Izuku titled his head curiously.

"A secret? Well I certainly wasn't expecting that." Izuku admitted, looking to the man curiously, giving him a once over. "I can only guess what it could be. Based on the fact we've never met before now, it can't be anything to do with just the two of us more than likely, and he was reluctant to share in part because I'm a fan, so that means he's likely not sharing with any of the students, therefore the only other connection we can have is through the staff, so this is something all staff members will know and by extension, something I likely would learn anyways due to how much time I spend with you all."

All Might went wide eyed at the green haired teens deductive skills while Nezu clapped with a proud gleam in his little black beady eyes. "Thank you Izuku for perfectly encapsulating part of exactly why I am asking All Might to tell you this. You see All Might, with a mind like young Midoriya has, and with the fact he will be with us far more often than the average student, there is an incredibly high likelihood, if not outright inevitability, he would find out your secret anyways which would make it far easier to nip this in the bud now. Especially as Izuku doesn't tend to let secrets stand before him."

Izuku shrugged, not apologizing. Secrets could be necessary sure, but often they were messy and drove conflict when things could be resolved much sooner. His only secrets were the kind he kept out of villains hands, nothing else. So yes, he found secrets to be quite irritating.

The blond sighed, scratching his neck. He seemed to be slowly easing into the idea. "I suppose it makes sense… it's just, it's something incredibly important to me and could fundamentally change a lot were it to leak. I understand it might be annoying to be brought in to only find out about a secret and not what it is but I am just… it is not something I reveal to just anyone and never with a light heart."

"Right. You've never met me before, so you have no reason to tell me anything. I get it, no obligation. You can't put faith in a stranger with something that affects your whole life." Izuku easily surmises. All Might nods apologetically and Nezu's smile grows.

"I was anticipating you would think that All Might. So I hope your faith in me holds strong as you have claimed it has before, while I tell you about my own faith in my student. Have you heard the old line about peer pressure, All Might? 'If your friends jumped off a cliff, would you also jump off a cliff?' Allow me to repurpose it to explain.

"Were, in this very moment, Izuku, of sound, mind, and body, to jump off a cliff, I would follow him with one hundred percent faith. I would simply know, with all my trust, he knew what he was doing, I would know I would be fine for I know he would have done all due calculations, I would land and I would find myself there with him, as he gave me a sound, logical reason for his actions that made everything he did in that moment make perfect sense.

If Izuku jumped off a cliff, the appropriate next move is to follow him off the cliff. That is my faith in him, far beyond that of any simple trust in a non-disclosure legal agreement like most employees of mine. Enough that were he to tell me, me , of all people I had made a miscalculation, I would know I would need to check and reaffirm myself. The faith in an employee is based on shaky grounds and threats of legal action, it compares nothing to my faith in my student, and my friend. That is what I want you to understand when I ask you to trust him."

Izuku felt his throat tighten slightly, as a slightly wobbly smile came onto his face at Nezu's faith in him, trying to ensure he didn't just end up wailing there on the spot after he'd gone so long managing without crying at every little thing.

All Might's face was stunned as he soaked that in, before he looked to the teen once more. His conflict slowly gave way, a simple look of tiredness overtaking him. "Okay…. Okay, if you're serious about this. Young Midoriya, I need you to promise you won't freak out when I do this. I will… look quite different in a moment."

Izuku titled his head confused but cleared his throat, readjusting, giving the man a curt nod and serious look. "I promise."

All Might sighed, as steam suddenly began rolling off him. Then to Izuku's shock, the man literally deflated. His muscles regressed and he shrunk. In his place, while still quite lanky, was an ultimately shorter man with a body so skinny Izuku immediately found himself concerned about his health. His eyes were sunken and defeated. "Young man…. This is my true form."

"You're…" Izuku took a deep breath to adjust to this revelation, before frowning. "S-Sorry sir, give me just a moment. You're still…. You're still the same person?"

"Yes, I am the exact same. However, when I'm not in my muscle form, this is how I look. You have met All Might, but I am the man behind the hero, my name… Is Toshinori Yagi." The now skinny pro explained, coughing slightly. Izuku's worry only increased when he saw a few small flecks of blood on the edge of his thumb. "I am sure you have a lot of questions but allow me to deal with the one I assume is burning brightest in your mind. I… am not healthy, not anymore. My muscle form used to simply be my real form, yet that changed in recent years and I have slowly been losing my ability to access my muscle form over the years. Nowadays, I can only maintain it for about three hours a day."

"Which would be why Nezu wanted me to know, because the more you have to use it to hide your identity…"

"The more it weakens me when I actually require that strength, precisely." All Might nodded, glad to see the quirkless student was catching on quickly. "So the more I can stay in my real form, the less danger there is in case something like a villain attack DOES occur, and the less likely I am to miss classes."

"So that's what happened with your injury." Izuku said, talking more to himself than anyone else as he processed this information, before looking up to see both teachers had completely frozen up and were looking at him like he'd grown a second head. "What? Is there something on my face?"

"Izuku… That injury is one of the best kept secrets in Japan, even more than All Might's true form."

"So how on Earth did you already know before we told you, young man?!" Yagi asked, shocked more than anything. Izuku flushed and scratched his neck as discomfort set in.

"Right… Well uh, b-because I was there when you were healing?" Izuku spoke up, making Nezu perk up in sudden realization as his small eyes quivered and he sighed. Yagi gaped, before shaking his head. "I mean I… When you wouldn't stay in bed, I was… It had been about a year since I began taking classes at U.A. more or less. I can't remember which class I was going to, all I know is I was about to turn the corner and… I saw you, All Might. I saw you bloodied and bandaged and crawling along the wall."

"Oh… oh dear…" Yagi looked down, gritting his teeth, clearly not enjoying remembering that time. "You could have only been a child then… I am so sorry you had to walk in something like that at that age."

"I… I won't lie and say it didn't affect me." Izuku admits, putting his hands together with a heavy sigh, a part of him finally happy to get this off his chest. "I spent whole nights, just sat motionless. Sometimes I'd cry, others I'd just…. Sit there. The strongest person in the world that I knew, the strongest… needed a successor, had been injured to the point of not being able to continue on himself, to hear... to hear the closest thing you know of to a god on earth was going to die?"

Everyone shuddered as the word hung in the air, before Izuku pressed on. "I was too shocked to react at first… I didn't know what I was even meant to say. How was I supposed to bring something like that up? So I… I didn't. I was scared of acknowledging it, so if I just… didn't bring it up, somehow it could stop being true. I learnt better. So yeah, it messed me up at first…" Izuku sighs, before looking straight at All Might. "Yet in some ways, I'm thankful. Not that you got hurt of course. I don't want anyone to but… I want to be the kind of hero that saves everyone, that can smile no matter what and save everyone. Yet back then, a part of me was happy to just be a hero at all. I forgot to keep pushing myself. When I finally registered what it meant, I had a wake-up call. I can't just be a hero, some random hero lucky enough to get on by despite being quirkless. I need to be the absolute best hero I could ever be; I have to… I have to be trying to surpass you every day, no matter how weak I am, how little power I have in comparison. I will save everyone , and to do that, I have to be the strongest, greatest hero I could ever be."

Nezu and All Might both sat stunned for a moment at the green haired teen's impassioned words, his reaction to such an event he was never meant to see. All Might swallowed for a moment. He still couldn't say he was quite sure what he thought of this quirkless hero thing, he needed to give it more thought.

But he couldn't deny Izuku was strong when it came to his mind. To find strength where others would find terror. It was inspiring in a way. Certainly, that kind of will was befitting anyone with a heroic heart. That much he knew.

"It's… not hard to see why Nezu thinks so highly of you now, I have to admit." The skinny pro chuckled, scratching the back of his head. "He mentioned you have a notebook collection?"

Izuku blinked in surprise, before nodding and reaching into the inner pocket of his blazer, having asked for a bigger pocket on both sides, one specifically for this. "Y-Yeah, I always try to keep at least one notebook on me at all times in case I see any new quirks I want to analyse or find something really important I need to keep jotted down. This one is my most recent one."

All Might nodded, quickly skimming through it, smiling at the back half being empty. "Well then, young Midoriya, I heard you have plenty of other signatures already. Shall I add mine to the list?"

"….YESPLEASETHANKYOU!" Izuku immediately said, eyes sparking and making the teachers laugh, the somber mood from before beginning to disappear. The blond borrowed a pen from Nezu, writing his signature within.

"I have to commend you on your attitude young man. It takes real strength to be able to handle something like that and turn it into fuel to better yourself instead of something far more negative." Yagi complimented him, as he put the finishing touches on the signature before handing it over. "I was hesitant, but I think this arrangement can work out. Just remember, you cannot tell anyone else about my injury or true form, the panic it would cause is far too great."

"I understand completely." Izuku nodded, to the number one pro's satisfaction as he began to bulk up again, opening the door.

"Then I had best be off! I am still planning lessons with the help of my fellow co-workers! Ahaha! Now please, excuse me as I disappear, with style and grace befitting of JUSTICE!" With that, All Might turned around and took off in a dead sprint down the hall, making Izuku chuckle before he turned back, only to see a deadly serious look in Nezu's eyes.

"…The secret wasn't the only reason you called me here was it?" Izuku asked with a sigh. The serious look was something Nezu only gave on rare occasions, it demanded the same level of attention and reaction as any villain attack.

"No, it was not. I would assume you remember our conversation from last week." Nezu asked simply, as he frowned. Izuku felt his skin crawl as he could feel silent anger pour out from the hybrid despite it not showing on his features. Despite his serious yet neutral gaze, molten rage could be boiling beneath the surface.

And for once, Izuku knew the cause already. He wanted to deny it, to think anything else but he knew he couldn't. They talked about only one thing that demanded this kind of treatment last week.

Carefully, as though extracting the delicate heart of a child in the midst of surgery, Nezu pulled out a manila folder, pushing it across to Izuku. "I gave it a once over myself. As we have established to All Might multiple times, you're smart, and even an idiot could figure out the truth hidden within these documents. I can't believe I'm agreeing to let you investigate this case on your own."

"I know uncle Nezu… but, I think in the end, it's for the best."

Izuku always thought his dread would be minimal and his excitement would be endless when he got his first real hero job. Sure there could be risk but he'd finally be a hero and he could deal with it.

Instead however, it was like the opposite had occurred, dread crawling through every inch of his body as he lifted the folder. He wouldn't be looking it over until later but he could still see part of the first document. The one who had caught his attention.

' Vigilante alias: Viscera

Real name: Unknown

- Note: Name refers to the crime scenes, having been given a name by the media. When he is done with his criminals, all that is left… is Viscera.'

Izuku sighed. He did not look forward to what came next.
