Punching Things Isn't a Quirk

by A Sometimes Lazy Writer

Saitama and Genos have dealt with weird things happening to them before, but tumbling into another world after messing with an alien warp drive took the cake. Tensions rise as the powerful duo make ripples in the hero (and villain) society of Japan. How does everyone react? With exasperation and annoyance, of course!

"Kaachan!"

"…she's buying a stairway to Heaven…"

"Kaachan!"

"…sometimes words have two meanings…"

"Kaachan, seriously, wait up!"

"The fuck?"

Several students fresh out of class quickly stepped out of the way of the hurried teenager, watching with mild amusement as the aforementioned 'Kaachan' turned to face this new arrival. "Deku?"

Izuku huffed with exertion as he bent over, bracing himself on his knees. "I've been…trying to catch up to you…for the last two minutes…"

Katsuki blinked as he pulled out an earbud. Even from this distance, Izuku could hear ear-splitting rock music playing. "I didn't hear shit. Yell louder next time."

Nearby students tittered with muted laughter until Katsuki gave them one of his customary glares. "What do you want? Did I leave shit in your house again?"

Izuku let out a weak grin. "No, not that, it's just…can I talk to you for a second? It'll be quick, I promise."

The teen thought for a moment and shrugged. As long as it was quick. His old lady set up a curfew since the USJ attack and if he was late, she was gonna kick his ass. "Sure. But if this takes too long, you're taking the blame with the old hag, not me."

Izuku flinched, but nodded. Kaachan's mom loved them both dearly, but she was scary when she needed to be. He remembered accidentally helping Katsuki with a prank on their teacher when they were in elementary school, which involved a few gallons of vegetable oil, a whoopie cushion, and a tub of Rocky Road ice cream. His mom hit Kaachan hard enough for him to see stars, and gave Izuku the most terrifying lecture of his life until his own mother showed up.

The two made their way down the hall to one of the many rest areas dotted around the school. This one gave a pleasant view of the surrounding grounds, and the teens could see the rest of the students leaving the premises to either go home or hang out together elsewhere. Katsuki slipped a coin into a nearby vending machine and pulled out two canned sodas, handing one off to Izuku, who muttered a 'thanks' before cracking it open and taking a hearty gulp.

Katsuki did the same before waving his arm vaguely. "So, what is it? Is this about what All Might told you?"

Izuku nearly choked on his drink. "How did you know he told me something?"

The blonde looked at him as if he was stupid. "You told me you were late because you were talking to him, dumbass."

Oh, right. "O-Oh yeah, I forgot. But this has nothing to do with All Might! I mean, if it did have something to do with All Might, I would tell you, but this doesn't have anything to do with him, so there's nothing wrong!"

Izuku's childhood friend rubbed the bridge of his nose. "Deku, shut up before you say something you're not supposed to. You're still a horrible fucking liar, you know that?"

The green-haired teen blushed. He was right, of course. He was never able to pass a lie in front of anyone, especially Katsuki, who once said that he could 'smell bullshit a mile away.' The first time he actually was successful in a lie was when he told Kaachan about his late-blooming Quirk, but even that was a technicality rather than a straightforward answer.

Katsuki huffed. It's not that he wasn't interested in why All Might asked to see Deku. In fact, he was almost burning up with questions. But it wasn't his place to ask, and seeing how it was apparently a secret, he knew he had to shut Deku up before he said something he regretted. "Then what's up? I'm drawing some blanks here."

Izuku took a quick breath. "Why don't you want to give the speech at the festival?"

Katsuki blinked. "The opening speech?"

Izuku nodded. "Mr. Aizawa said that he talked to you about it, but you turned him down."

An unspoken 'why?' hung in the air, but both knew it was there. To Izuku, it didn't make sense. All his life, Kaachan was always trying to get to the top. Even menial things like who could cook the most food or win the most prizes at claw games were literally life or death to him. He was all about victory, though that wasn't always a bad thing. Izuku found it admirable, in fact.

Which was why it was baffling to him that Kaachan would willingly drop a chance to get noticed by the pro heroes. He wasn't one to just wait for people to notice him: he reveled in being seen, and his attitude clearly reflected that.

The blonde teen cracked a small smile as he leaned back into the couch cushions. "You mean you don't know the answer to that, dumbass?"

Izuku frowned. "To be fair, Kaachan, you don't really give anyone any hints on why you do what you do."

Katsuki shrugged. That much was true, he'd give him that. "I just don't think I deserve the spot yet."

"What do you mean? You've got the highest grades in the class! Not to mention holding your own back at the USJ. No one else is qualified for this, so why me?"

That last part wasn't strictly true, since Todoroki was a close contender and could have easily taken the position of being the opening ceremony speaker. But it was better not to mention that to Katsuki, who clearly didn't like the other teen very much. Also, Izuku didn't think that Todoroki was the public-speaking type. He could very well just say something along the lines of having a fun game and leave the stage.

Kaachan smirked, clearly pleased that his childhood friend held him to such high regard. That was one thing that never changed over the many years the two had known each other. "Still doesn't change the fact that I think you should do it instead."

Izuku finished the rest of his drink, perplexed. "But why? You of all people would want to do this."

Katsuki hummed. "Don't get me wrong. I want nothing better telling the rest of the extra's at UA to shove off. But you remember when that creepy hand bastard sent that thing after All Might?"

How could he forget? That thing had plagued Izuku's dreams over the last few days. It always made him sick to his stomach on how close All Might was to dying if Mr. Saitama and Mr. Genos didn't intervene. He nodded.

"You were the first of us to move."

Izuku waited for a follow-up to that cryptic statement, but it seemed that Kaachan was going to say nothing else. "Is that it?"

"What else do you want me to tell you?"

"So that's it," Izuku spluttered, "You're making me do the opening speech because I moved first?"

The blonde shook his head in apparent exasperation. "Come on, Deku, use that freaky brain of yours to think about it."

He allowed the hapless teen to dwell on it for a few seconds before he took pity. "You didn't hesitate, Deku. Even if you knew that you probably wouldn't have been able to do shit, especially after breaking your own damn legs again, you still tried to help All Might."

"But so did you, Kirishima, and Todoroki! You guys were right behind me!"

Izuku was treated to a scoff. "But you didn't hesitate. At all. Trust me, I wanted nothing more than to blow that monster to bits, but I still knew my limits. I knew that I probably was gonna do jack shit to that thing."

This was a rare confession. Katsuki never admitted he was too weak to do anything. He had such a confidence in his abilities that it nearly bordered on cockiness.

"But then you," Katsuki said, leaning forward, "You jumped in without a second thought in that freaky head of yours. You should've known that you would barely be able to touch it. Useless Deku ran in before me. I ain't happy about it, but I think you're selling yourself a little short."

Izuku barely noticed the can crumpling in his hand. "But I never ended up doing anything. I would have died if Mr. Saitama and Mr. Genos didn't come when they did."

He still remembered the terror he had felt when the Nomu turned to face him faster than he could blink. The way its mouth moved as if to bite straight through his flesh, and the way its arm swung through the air with the force of a battering ram. He could have died. He should have died if the two mysterious heroes didn't intervene.

Only now did Izuku realize how close he came to losing everything he worked so hard for. One for All would disappear, his first friends outside of Kaachan would have mourned him, All Might would lose a successor, and mom would have hated herself for the rest of her life. It scared him.

But even worse, he knew that he would do it again in a heartbeat. He knew that if a situation happened like that again, he would have gladly risked his life to save another. His self-destructive nature was always hanging over him, but he couldn't bring himself to care. Not when lives were at stake.

A sharp pain lanced through his scalp. Izuku let out a weak yelp as he glared up at Katsuki, who had rapped him harshly on the head. "Don't make that fucking face, dipshit."

Before he could get a word in edgewise, Katsuki swiped Izuku's ruined can from his palm and tossed it into a recycling bin. "Trust me, I know that you know how godamn stupid you were. And I know that you're gonna do it again if you have to."

He took a breath, although it sounded more like a hiss. "That pisses me off."

Izuku blinked. Katsuki continued. "You scared me, you know? I really thought that you were gonna die. I had to watch you break your useless legs, again, to try and fight that thing, again. You and I both know you wouldn't have done shit.

"But, I admit, you kinda impressed me. Even if you were an idiot and you could've died, I knew for a fact that you deserve this. Useless Deku, the little shit that jumped in before anybody else."

Izuku knew now that Katsuki wasn't just talking about USJ. He knew that Kaachan didn't like to think about the Slime Villain, but he was willing to suck it up and tell Izuku that he admired him. Wow.

Katsuki growled as small tears started to fill up in the other teen's eyes. "Quit your godamned sniveling, Deku! Don't think that I'm gonna make your life easy on you either. I'm still pissed off that you could've gotten your lame ass killed. And I'm gonna beat the shit out of you in the Sports Festival for scaring the crap outta me."

The green-haired teen let out a warbling laugh as he rubbed his eyes. "But…what do I even say? You know I can't do this, Kaachan. I can barely talk to the rest of 1-A."

"You can, and you will. I ain't letting you embarrass us in front of all of Japan. I'll even help you write the godamn speech if you can't think of shit."

Knowing Kaachan, the 'help' would probably be adding in a mixture of curse words and half-concealed insults at the rest of the student body. He let out a tiny giggle thinking about what Kaachan's speech would have been like if he had chosen to give it. "T-Thanks, Kaachan."

The ash-blonde teen roughly pulled Izuku to his feet and tossed him his discarded backpack. "Buy me some ramen on our way home and we'll call it even for now."

Izuku nodded, pushing down a watery cough. "Extra spicy?"

"Hell fucking yeah."

[-]

"So, let me get this straight. You two are from another planet, where your Hero's Association is constantly at war with villains and monsters, the latter of which are not human, and both are trying to subjugate or destroy the rest of humanity. Then, only a few days ago, your planet was attacked by an alien overlord named Boros, who was then defeated by Mr. Saitama."

"Yes."

"On top of that, the Hero's Association ordered an investigation of the alien spacecraft, where one of your heroes, Child Emperor, who is 10 years old, accidentally set off the ship's warp drive, sending you and Mr. Genos tumbling into the USJ, where you encountered All Might locked in battle with the Noumu."

"Yeah, that sounds about right so far."

"…And, as Mr. Genos pointed out, the villain who we identified as Kurogiri shares a remarkable energy to that of the…alien warp drive."

"Yes, that is correct. I scanned a near perfect match of the villain's Quirk and the portal that brought us both here."

"As far as your powers go, Quirks are nonexistent in your world, and only a fraction of the human population have powers of any kind. And you say that even some of the heroes on your planet do not have any abilities."

"Precisely."

"…Excuse me for a second."

Detective Tsukauchi exited the interrogation room, sighing as he rubbed his throbbing temples. He didn't even notice where he was going until he nearly ran into a sudden bulk in front of him. "Oh, my apologies. I didn't think you would arrive so quickly."

An annoyed snort was all he got as the number two hero, Endeavor, crossed his arms and glared through the one-way glass that separated them from the strange duo inside the room. "Don't tell me you wasted my time by calling me here to watch two clearly insane men, Nezu."

Nezu rose from his adjusted seat next to the window. "Now, now, Endeavor, you and I both know that I would never call upon you for something that I don't believe is a threat. Are these men insane? Maybe. Are they dangerous if not watched? Most likely."

The flame hero fixed his eyes upon Saitama, who looked like he was about to fall asleep any second. "Clearly," he scoffed, "As if these bumbling fools have the strength to rival that of all the top heroes in Japan. That Noumu must have been on his last legs when he got destroyed."

"I don't believe so, Endeavor," All Might replied, standing up from his place near the one-way glass, "While the Noumu was severely weakened, I have no doubt that it would have still been a match for even the most experienced heroes.

"But Mr. Genos was able to blast the thing with firepower nearly rivaling yours, and Mr. Saitama took the beast down with no effort."

The room suddenly brightened as Endeavor's flames rose in anger. "Are you insinuating that this child rivals me in strength, All Might?"

Endeavor's jaw tightened as the hero simply let out a booming laugh. "Perish the thought! I was just comparing his abilities with your own. Mr. Genos has not yet been pushed to full strength, but I do not believe he will ever raise his power against us, seeing how we are all fellow heroes."

"Are we positive they are heroes, though?" Aizawa inquired as he pushed off from behind the shadows of the room. Tsukauchi almost flinched. He didn't even notice that the underground hero had arrived to the police station already. "For all we know, they could be playing dumb and pretend to be working with us in order to learn more about how we operate and break out whenever they can."

Endeavor let out a derogatory snort as he pointed at Saitama through the window. "Do you honestly believe that he has any kind of plan going on? I've seen smarter looking street thugs."

Nezu ignored the way Mr. Genos's head quickly swiveled in their direction with his face tight with annoyance, as if he had heard them through layered glass and soundproof walls. "Now, now, I believe Mr. Aizawa's feelings are well-founded. But Detective Tsukauchi has made sure to prove that they have no underlying motives. They are simply lost and confused."

"Don't tell me you believe in this nonsense of them being aliens from another planet. No Quirk on Earth is able to transport anything across space. And they are clearly human."

"But," Nezu smiled, "they are not from Earth. Therefore, their rules can very much differ from ours. Let us assume that they are not as crazy as they appear. If they are beings from another planet or even another dimension, we should be trying to help them instead of jailing them against their will. And maybe they will be able to help us in turn."

Aizawa snorted. "It's not like we can stop them, anyways. If they don't have Quirks, then I'm useless against them. The only chance we have is letting the strongest heroes subdue them if they get out of control."

All Might lifted up a bandaged arm. "As much as it pains me to say this, I do not believe I have yet recovered enough to fight anyone at full strength yet. And I do not wish to fight these two. They saved our students and we cannot forget their assistance in taking down the Nomu."

Endeavor once again stared through the glass, noticing that Genos's eyes seemed to meet his, even through the mirrored surface. "They killed the Noumu. I do not care whatever universe they say they came from, but they killed a human being. That is still unacceptable."

Nezu nodded solemnly. "I am not going to argue with that. However, their rules are again different from ours. If they mistook the Noumu for a monster, then it would make sense for them to treat it as such. However, I strongly believe that they will not harm a human. I have seen the way Mr. Saitama and Mr. Genos has interacted with the students. At the very least, they are good people with misguided intentions."

"So what, are you saying we should let them go free?"

"On the contrary. I am saying we should not keep them here against their will and instead give them some freedom, albeit with some security."

Tsukauchi lifted an eyebrow. "Do you think we should help them return back to their planet? According to Genos, the villain Kurogiri is vital to creating a portal back to their home. I am not exactly sure how a Quirk is going to transport them across billions of miles of space, but it could be a start."

Nezu nodded. "Figuring out more about these mystery villains is a top priority. They knew too much about what the USJ trip schedule was like, and capturing this Tomura Shigaraki and Kurogiri is a good step into finding the spy in our network, and to assist the two back to their world."

It is also a good step in figuring out who and where this mystery boss is. Even if we are almost certain it is All for One, we need to find out his location and how he survived.

"What are we going to say to everyone about these two?" Tsukauchi asked, interrupting Nezu's constantly rolling thoughts, "Everyone knows by now that they were at least present at the USJ, and I don't know what to say to the press once they get that information."

"Wait just a minute," Endeavor spluttered, "You cannot be seriously considering letting these two go free? This entire thing is ridiculous! Even if what they say is true and both are not insane, the government should be handling this, not us."

"With all due respect, Endeavor," Nezu replied, "UA is more than equipped to handle situations such as this. Of course, this is a bit out of our area of expertise, but as of now, the top priority that both parties can agree on is finding the villains responsible for the USJ attack."

The flame hero glared at the principal with such vehemence, it was amazing how he didn't vaporize on the spot. "This is idiotic. It is a waste of time to let these two fools be babysat by pro heroes. It's too much of a risk to the students and to the reputation of UA."

"I did not realize the safety of the students were of any concern to you, Endeavor."

Aizawa held his gaze when the pro hero turned on him, his face contorted in rage. "You dare insinuate—!"

"Allow me to worry about the safety of my students, Endeavor," Aizawa interrupted, "You should be busy with your own matters."

Several tense moments passed as the two stared down at each other, one the symbol of quiet sternness, and the other the symbol of barely controlled rage.

Tsukauchi glanced nervously between the two heroes. He swore he could feel the temperature increasing in the room, if the sweat was any indication.

He wasn't stupid. Even he knew the rumors surrounding the relationship between Endeavor and the rest of his family. Nobody really knew the full details of what happened in that family, but it was enough to keep him on edge. While he did worry about the condition of Shoto Todoroki, it wasn't within his jurisdiction to investigate, unless Endeavor gave him a reason to.

All Might broke the tense atmosphere by doing the most All Might thing possible and placing his hands on the two hero's shoulders. "Cut it out, you two. There is no time to throw accusations around. We are all on the same side, after all!"

Aizawa took a moment to glare back as best as he could with the rest of his face bandaged, but ultimately turned away. "I'm going to talk to the two about their options. We will decide what to do depending on their answers."

Endeavor violently ripped All Might's hand off his shoulder as Aizawa shuffled towards the door. "Don't expect me to babysit those two, Nezu," he warned, "If I even get an inkling of ill-intentions from them, I will put an end to it myself."

"And when that happens, you will be the first to be contacted," Nezu chirped, a noise far too positive for the mood in the room. "I will call on you later if anything changes."

The door slamming hard enough to crack the frame was the only answer they got.

All Might let out a sigh. "Always the hot-headed one…"

Nezu sympathetically patted his leg. "It can't be helped. I had hoped to convince him to help watch the two, seeing how Endeavor might be able to deal with Mr. Genos' power, but we can make do without him. It is clear that he has no intention of assisting us."

Speaking of the two… All Might glanced through the window, seeing Aizawa enter the room. "I cannot help but feel bad that we are limiting their freedoms in such a way. They have proven themselves to be heroes and nothing they said to Tsukauchi was a lie. Not to mention they saved me and the students."

"Trust me, Toshinori," Nezu replied, "it is more for their safety than ours. If the villains decide to exact their revenge or capture them, it is good to have some extra protection. These two are strong, but even they would be hard pressed to fight against the full might of the League of Villains and whoever is controlling it from the shadows."

Through the glass, Saitama stifled a yawn. He hoped so. He didn't hold high expectations for a fight that would make his heart sing in this world, but it was always good to dream.

[-]

In the end, the two were able to walk away unshackled.

The detective walked them over to the exit where the rest of the heroes were waiting before excusing himself. "There's been some kind of breakthrough in the identity of the Noumu," he explained, "Hopefully this brings us closer into finding out why he was acting more like an animal than a human."

Saitama yawned widely as he stepped into a black van, along with Genos and the shaggy dude. Erasingface or something.

His relief was palatable when Erasingface walked into the room to list out their options. He wasn't really surprised much by them, seeing how he had heard the entire talk through the one-way window.

He had also heard what that angry-sounding hero had said about the two of them, and he was forced to tap Genos on the leg after he noticed his fist starting to clench in annoyance.

Saitama appreciated the fact that Genos was so willing to protect his image (even if it was a little creepy), but he could take care of himself. He didn't care that he was being labelled as a villain. If he tried to say otherwise, he was gonna trip up or say something that they wouldn't like. He was never a good negotiator anyways. The best he could do was to keep doing his job. Being acknowledged was nice and all, but if he was put on a pedestal just because someone put him there instead of him actually working for it, he would rather stay as a normal B Class.

He turned to stare out the window, fighting sleep as he watched the night life of whatever city this was take place. There seemed to be way more people on this planet than his own. Part of that may have had to do with the monster attacks that took place literally every day. There was just too much danger with too few heroes to stop them all.

Speaking of heroes, Saitama surreptitiously glanced at Erasingface, not surprised that was staring at him.

He knew that he wasn't the sharpest knife in the drawer, but he still realized that they needed help. Genos was smart and all, but Saitama doubted that even he knew how to build a portal back home. Best bet they had was to catch those villains and beat the answers out of them.

He could work with that.

Eraserhead suddenly spoke up from his seat, breaking the silence that had started since they left the police station twenty minutes ago. "If we're going to be stuck together for the time being, I want to make a few things clear."

Genos felt his brow furrow. "Yes?"

The underground hero shuffled forward a bit, his bandaged face doing nothing to hide the cold look in his eyes. "First, I want to make it clear that we are going to be calling the shots. If we find a lead on the League of Villains, you and Saitama are not allowed to go off on your own without direct permission from a pro hero, or accompanied by said hero."

Even Saitama seemed a little upset by this, but Aizawa raised a bandaged hand, silencing their complaints. "This is not to spite you. It is purely for your safety, and the fact that you two have no idea how this world works." His voice halted a bit, as if he was still trying to convince himself that they were from another planet. "And even if you understand more of our customs, we still cannot let you go off alone, since you are now probably considered a high priority target by the League. For all we know, they could try to tangle you up into a trap."

Genos begrudgingly agreed. It was true. Even if he spent the next week absorbing as much as he could about this world, it was going to take a long time to cover everything. They were approaching this blind if they tried. Loathe he was to admit, they would have to play along with their rules for the time being.

"Second, you are to be granted access to the school facilities. Nezu is allowing you to have access to the UA database, although you will not be allowed to look at confidential information like student backgrounds.

"If you do need to look into something confidential, you can ask either Principal Nezu or any of the UA staff for permission. If we say no, that is a solid no. Some things aren't meant to be seen by outside eyes."

Genos and Saitama nodded, the former failing to mention the fact that he had a built-in hacking program that would make quick work of most security features. Better to not let that slip, however. They would even more hesitant to give him a console than they already were.

"Third, we will be giving you temporary identities. The press is going to go crazy once they catch wind of your involvement in the USJ, but nobody is going to know who you are. Nezu already contacted an associate in the government to forge some fake IDs for you, which you will both carry around. Understood?"

Saitama raised a hand, as if he was one of Aizawa's own students. "I don't really know about how you guys work around here, but isn't that illegal?"

Aizawa fixed him with a deadpan stare. "Would you rather the public find out that you literally don't exist?"

"…Good point."

The teacher sighed and leaned back into his seat. "You would be right, though. Usually something like this would be only accessible through the black market. But since the government is probably going to let us handle this situation, seeing how villains are mostly at fault here, they are willing to let it slide."

"Do you know what 'Quirks' you are going to register for us?" Genos asked.

"Hm. I would assume for you, we're probably going to list your power down as an energy manipulation Quirk, seeing how you have the 'support items' for it. As for Saitama, we'll most likely going to list yours as a simple power enhancement Quirk.

Aizawa closed his eyes. "Of course, those descriptions are going to change once we get back to UA."

Saitama and Genos blinked. He couldn't possibly mean…?

"That's right. You two have the distinct privilege of sparring with some of the top heroes in Japan. Registering Quirks need a certain amount of detail. So we need to make sure we know most of how your powers work. If we just give half-assed explanation for your 'Quirks,' people are going to get suspicious."

Saitama bounced in his seat as the van drove over a particularly large pothole. "You guys aren't worried about things getting out of hand?"

"If it does, then we will stop immediately, and we expect you to do the same. This is not going to be a fight to the death. This is just to showcase your abilities for the record. If you continue to fight after we explicitly tell you to stop, then expect some of your privileges to get revoked. Got it?"

Saitama muttered an affirmation, but a few moments passed before Genos gave his answer. "It does not seem fair that we are the only ones being judged, Eraserhead. If possible, I would like to learn more about your abilities as well."

Aizawa's eyes narrowed. "I cannot speak for everyone at UA, but feel free to ask Nezu for more information about our Quirks. Simply put, I can nullify a Quirk that is in my line of vision. But if I blink or break line-of-sight, they're able to use them again. And you've experienced the rest of the staff's Quirks before."

The van rumbled to a halt and a quiet knock echoed from the wall separating the back from the front seats. "Eraserhead, we've arrived."

The trio stood to exit. "Oh, and one more thing."

Aizawa took their silence as a sign of their attention. "We've talked about this before, but we expect you two to play by our rules. If we end up having to fight villains, you will capture or defeat them alive. Unless you are faced with an extreme circumstance, you will not kill anyone. Your world may be able to afford those losses, but we are not. Is that understood?"

His eyes flashed dangerously to get the point across.

Genos coolly stared back. "Understood."

"Yeah." Saitama followed.

The crimson glow faded. "Good. Let's get to faking your Quirks."

[-]

All Might grinned as Eraserhead and the other two heroes entered Gym Gamma. "Welcome, Saitama and Young Genos! I hope you can forgive our earlier treatments of you?"

He noticed the teen's brow twinge in slight annoyance before smoothing out again. "It is fine. However, I wish you had more trust in us being heroes than accomplices to some villain."

"Apologies. But we couldn't take any chances, especially with that particular villain. It is hard enough to find information on him to begin with, so we had to jump on every single opportunity."

Saitama shrugged. "Bygones are bygones. I'm fine as long as you guys don't start randomly attacking us again."

All Might let out a booming laugh. "We have a common goal now, and you will be treated as friends and allies. 'The enemy of my enemy is a friend,' after all."

He turned, leading the trio into a large, empty space. Saitama almost looked disappointed. He was expecting some high-tech equipment to play around with, but all that was inside was a concrete floor and three other heroes: the weird blocky monster, the black thing wearing a trench coat, and some really short grandma wearing a lab coat.

"Allow me to introduce you to members of our esteemed staff," All Might gestured widely, "This is Cementoss. He teaches modern literature; however, he is also able to create structures to assist the training of our students."

The bulky hero bowed. "It is a pleasure to officially meet you both. I thank you for protecting our students."

Saitama waved. "We were just doing our jobs. Don't worry about it."

"And this is Ectoplasm. When he is not teaching mathematics, he is assisting students with his Quirk in order to test close-quarters combat."

The hero simply nodded in greetings.

"Lastly, we have Recovery Girl, our on-site nurse here at UA. If you ever become injured, be sure to pay her a visit, and she will be able to get you into fighting shape in no time!" His voice then dropped an octave. "Although, I do not know if her Quirk will be effective on you two, seeing how you are not from here."

Recovery Girl lightly smacked All Might's leg with her cane, which was strangely fashioned to look like a giant syringe. "Try not to push yourselves too hard. My Quirk drains you of your energy, so if you need to do something later, you're better off just riding it out."

She then hobbled over to Genos, who looked down at her with some interest. He could tell that this woman had seen her fair share of experiences. And judging from her introduction, he guessed that her Quirk had something to do with healing. That was an impressive power in and of itself. As far as he knew, there were no heroes with the ability to heal. Medical technology had made great leaps and bounds back in their world, but even then, the affected were forced to rest and recuperate in order to heal from their wounds. The only hero that had a similar power was Zombieman, although his was limited to only himself, and it was more of a regenerative ability rather than a healing one.

Recovery Girl hummed with displeasure as she circled the teen. "Boy."

Genos frowned. "Yes?"

"Principal Nezu told me that you have multiple prosthetics. Is it just your arms?"

"No. Over 95% of my physical body is mechanical. The rest are vital organs that could not be replaced, including my brain."

He barely registered the bare alarm that flashed across Recovery Girl's face, and saw the others flinch. All Might's smile slipped for a brief second, Cementoss looked shocked, and surprisingly, Ectoplasm's eyes shined with what looked like sympathy.

No matter. He had long accepted who and what he was. "And why exactly did the person who saved you build your body in such a way?" the woman asked. Her disapproval was apparent.

His eyes narrowed. "If you are trying to find fault with the doctor who saved my life, I will have to stop you. He first wished to give me a normal body to live out the rest of my days, but I was ultimately the one who made him make me the way that I am."

"But why?" she asked, "Why would you subject yourself to this? Why turn yourself into a weapon?"

Genos stared back blankly, as if she had asked him a strange question. "Is it wrong to want to hunt down the cyborg that destroyed my village and killed my family? Your world has many heroes, honored elder, and if such a tragedy occurred, I have no doubt that you will be able to bring me the justice that I deserved, had I been born here. But our world is different. Heroes are outnumbered, and although we are strong, we are also often overwhelmed. I was willing to fight for justice and bring that monster down. I believe it was worth it, compared to living out the rest of my days in fear and hatred."

For a second, Recovery Girl was at a loss for words. She knew that their world was harsh, but the extent of the darkness was much deeper than she had anticipated. No young boy should have experienced such pain and torment. Now he was driven by revenge and a twisted view of justice.

She sighed. What was it with these children so willing to tear themselves apart to become heroes? "I would like to see you after this to see how we can help you if you are ever injured in the future. My Quirk cannot work through mechanical prosthetics, so you are better off going to Power Loader at the Support Department to fix any damages. However, I will be taking my fair share of research on the parts of your body that is not machine. Do know exactly which organs I should be careful of?"

Genos nodded. "I have data from Doctor Kuseno stored in my memory banks. I can send it over to you after we are done."

Recovery Girl grunted and turned to face Saitama. "As for you, I would also like you to come to my office. I don't know if my Quirk is going to work on someone from another planet, but it is always good to try. I am also going to be conducting a physical, just to see what I am dealing with."

Saitama hadn't gotten hurt from a fight in literal years, but he nodded just the same.

The elderly hero pointed to an empty section of the concrete field. "Alright, I want Genos…what is your surname?"

"Surname?"

"Yes, your last name."

Blank looks.

"Your family names?"

Genos looked at Saitama, who shrugged. "Are we supposed to have more than one name?"

"…Never mind. Genos, you go first."

The teen quickly walked to the center of the field, accompanied by All Might, Cementoss, and Ectoplasm. "So tell us, Young Genos," All Might boomed, "What exactly is the source of your power?"

Genos tapped his chest. "My body is powered by an internal core that was created by Dr. Kuseno. It is extremely efficient, and does not require any external fuel, unless I exhaust all of its energy into my attacks. However, I am able to refuel it through food, which I can convert into biofuel."

Ectoplasm hummed. "If this core becomes damaged or loses its energy, I assume you will be incapacitated?"

"Precisely. My body will first run on emergency power, which will last for approximately 3 days with minimal activity. If I cannot refuel or repair the core within that window, I will die."

Cementoss looked a little queasy. "That seems extremely risky. We will have to talk with Power Loader to see if he can create any replacement cores for you in the meantime. Do you have any schematics you can show us?" A nod. "Good. Then let us go ahead and talk about your abilities. Other than firing energy blasts, can you do anything else?"

Genos crossed his arms. "My body has been augmented for maximum damage output and efficiency. I am capable of short-term flight, have increased physical strength and speed, and I possess multiple sensors to detect danger or changes in my environment."

Cementoss nodded and placed his palms on the ground. With a speed that even surprised Saitama, the concrete shifted and rolled in waves, until it eventually created a makeshift training course, complete with a track, pillars, and a giant cliff. "First, I want you to get to the end of the track as quickly as you can."

The cyborg stared at the field, mentally gauging his options. "This track is not long enough for you to get an accurate measure of my speed."

If those words came out of anyone else's mouths, it would have sounded unbelievably cocky. However, for Genos, it was just a matter of fact. At full or even normal strength, he would have been able to run several miles at breakneck pace without tiring.

The hero just shook his head. "It does not matter. We just need a demonstration so we can be as vague as possible on your Quirk registry without going into detail."

Genos dropped into a crouching position. "Understood."

All Might walked over with a tablet of some sorts. "Alright, we have our sensors trained on you. Feel free to go whenever you are ready, Young Genos."

A moment passed as Genos took in a breath. All Might was barely able to register a yellow light suddenly emanate from the teen's eyes before he literally disappeared.

The pro hero barely had time to blink before a sharp crack of wind and dust slammed into the audience, nearly sending the bandaged Eraserhead toppling to the floor if Saitama didn't grab his broken arm in time.

Eraserhead's grunt of pain barely registered in everyone's minds as they reeled from Genos' vanishing act. What was that?

He was suddenly aware of a lean figure at the very edge of the field, noticing with some alarm that the boy had gotten nearly 150 meters in less than a second. He matched Ingenium's top speed with no wind-up time!

Luckily the hero recovered quickly and turned to face the distant teen. "Impressive. I assume that is your maximum speed?"

Genos jogged over, taking care to not step on the shattered concrete that he had made when he started his run. "I was only able to use a little above my base power. In a confined space such as this, I would have almost certainly broken something."

Eraserhead internally screamed. Of course. Of course that was the case.

Cementoss hesitantly fixed the ruined floor. "I have not seen such speed matched by anyone other than All Might's…"

Ignoring him, Genos turned to face the numerous pillars that were planted into the ground like dead trees. "What do you wish for me to do with these?"

Ectoplasm walked forward. Clearly, he had recovered the fastest out of the rest of the group. "We would like to see a demonstration of your strength next. Destroy these pillars with your energy blasts as much as you can. I can also make a few clones if you want to show your combat knowledge."

Again, All Might gave him the all-clear, letting Genos unleash his power.

With the accuracy of a trained marksmen and the power of a tank shell, the cyborg let loose a barrage of high-energy blasts. They thrummed as they obliterated their targets, reducing them to so much as piles of rubble and dust. Even the smallest pillars were destroyed with pin-point accuracy.

The teen noticed Cementoss creating more pillars to spring up in random places, clearly to test his reaction time. Never one to disappoint, Genos' sensors activated, alerting him to any new introductions into the field as soon as they appeared.

A particularly dense field of pillars emerged from the ground, resembling a thick stone forest that may have been fused together with how close they were in proximity to one another.

Thinking quickly, Genos slammed his fists together, ejecting several smaller cannons from the weapons. It was not definitely not the same amount that he used in the mock bout with Master all those months ago, but it would be more than enough to deal with the army of new targets. "Incinerate!"

A billowing dome of raw energy erupted from his fingertips, although it was only around 10% of the power and size of the attack he had used on his Master. Needless to say, the stone melted upon contact, and even created a scorched crater into the cliff face behind them.

Silence reigned in the gym as Genos powered down, his metallic chassis steaming as it made contact with the cooler air. He didn't sense any new concrete formations. He turned to face the heroes as the signature glow from his body and eyes dimmed.

If he was a child again, he would have found the resulting looks on everyone's faces (minus Master's) to be amusing, but all he felt now was worry. Did they feel too threatened by his power?

All Might's uproarious laugh was all the answer he needed. "Amazing, Young Genos! I have never seen such skill from someone so young! I would not be surprised if you were a top hero back in your world!"

"It was nothing. There are far more skilled individuals in my world than I. I would not be surprised if you would be able to defeat me, seeing as you are the number one hero in Japan."

A flash of some unidentified emotion flickered in All Might's eyes, although he was quick to hide it. "Well then, we were able to see at least some of the power that you wield. Would you mind if we could see your approach to combat as well?"

"I do not mind."

The pro hero nodded at Ectoplasm. Saitama watched with morbid curiosity as the hero opened his mouth as far as it would go and spew out several large globs of literal saliva. The material jiggled and bounced as they hit the ground, and quickly morphed into carbon copies of the slender man. By the time he was finished, the twenty or so clones were completely indistinguishable from the original.

The clones situated themselves at various points of the field, with Cementoss quickly repairing the ruined surroundings and creating a makeshift city around them. "My clones attack in various forms. They are not going to be aiming to kill, but they are not going to go easy on you either. I ask that you do not use your energy blasts this time, but to use your enhancements to fight."

Genos took careful notice of where each clone was situated. "Will destroying these affect your original body?"

Ectoplasm shook his head. "These are merely puppets. They will have the same battle knowledge and skill that I possess, but their destruction will not have any negative effect on my person. However, they will not dispel unless you distribute a good amount of force, so feel free to let loose as you see fit."

Genos nodded, taking a combat-ready position. "Understood."

"Remember, young man," Recovery Girl warned, "If you end up getting injured, I want you to call to stop immediately." She then turned her brief annoyance to Ectoplasm, who wisely stepped away from the elderly woman. "And you. Don't you think that 23 clones are too much for one person to handle? Especially since he is no longer using long-range attacks?"

"Genos is strong," Saitama interrupted, bringing everyone's attention to him. "I'm sure he's gonna be fine."

The teen's eyes sparkled with barely-concealed emotion. If Master said he was strong in front of all these heroes, then he must have been getting more and more powerful! "Thank you, Master!"

The woman sighed. "Young man, are you sure you wish to continue?"

The answer was swift. "Yes."

This was not to just simply cooperate with the heroes of this world. Working with the UA staff guaranteed certain rights that were accessible to the both of them, and he would much rather have access to resources than be on the run with Master from heroes and the police force alike.

Nor was he doing this to show off. Like Master, he felt no real pride with his strength and skill. He didn't boast about his feats like Tatsumaki did, or feel a certain amount of elation from a good fight. But he did wish to learn how much he had improved, and with every new enhancement from Dr. Kuseno, he went out into the world to test them. This brief spar against the clones from this otherworldly hero were good for some data collection.

All Might cleared his throat. "In that case, I suggest everyone step away from the field. Cementoss, if you can kindly build us a viewing platform?"

Cementoss nodded and placed his palms on the floor, slowly raising a rough circle around the group skyward. It rumbled to a stop when they had reached about halfway to the ceiling. Saitama whistled appreciatively. "I'm surprised you don't work for a construction company or something."

The blocky hero nodded, accepting the comment as an acknowledgement of his abilities, even if the compliment was a little strange.

All Might walked over to the ledge, his towering figure casting a shadow onto the teen. "You will hear a buzzer soon, and that will start the match. If you hear a second buzzer, that means the fight is over. I would appreciate it if you can keep the damage within the field. We can only ask Cementoss to repair so much, after all."

Genos voiced his affirmation and crouched lower to the floor. His Search Eyes hummed to life, giving him a real-time HUD that immediately zeroed in on his targets. From the clones that he could see, it seemed that their internal body temperatures were maintained at a constant 37C, even though they didn't have any internal organs to regulate the heat. X-ray scans were largely unhelpful, seeing how they were made up of saliva.

It was very interesting to see the range of powers he had seen thus far. Since Quirks were so numerous in this world, there must be a near-unlimited number of combinations and unique abilities. While this did come with the positive of so many individuals becoming heroes, it did mean that it bred an equal number of villains.

Meanwhile, their own world had very few numbers of heroes, and even fewer actually had real powers. Part of him wondered what would have happened to the state of the world if powers were more widespread. While it sounded good on paper, it would have clearly created a fair share of conflict, especially if humans with powers had turned into monsters.

The buzzer suddenly screeched overhead, and the cyborg sprang to action.

Zipping around the many obstacles that littered the large field, Genos found several clones following closely, all matching him in agility. He was told that Ectoplasm had experience in close-quarters combat, and it was apparent that it was no understatement.

His HUD flashed just as a clone abruptly appeared right in front of him, coming around a tight corner that concealed its presence. A thin, metallic leg erupted from underneath the trench coat, aiming right for the teen's head

In one smooth motion, the teen ducked under the attack and buried an armored fist into the clone's chest, taking care not to activate his incineration cannons. This was not a monster, but a fellow hero, even if it was just a fake.

The force of the punch rocketed the body straight into a nearby wall, which promptly cratered under the impact. The clone slumped over and dissolved into a puddle of saliva, indicating that it was out of the fight. One down.

Genos turned the corner as the rest of the clones followed suit. Several jumped out from the shadows of the dim confines of the 'building,' and they were treated to a vicious storm of kicks, jabs, and punches that promptly blew them into puddles.

Genos leaped over a kick from a clone that appeared behind him. It seemed that Ectoplasm favored this form of combat. Why he did not use his arms was unknown: perhaps he only possessed legs, or had little experience using his arms to attack. While that limited the hero's combat prowess a bit, Genos had to admit that his techniques were solid.

The cyborg followed up the attack with one of his own, delivering a devastating axe-kick that buried the clone into the concrete. He reached out to grab a clone that had wandered too close, and used its momentum to toss it into the small crowd.

His golden eyes blazed to life as he assessed the situation. He was currently inside one of the many 'buildings' that Cementoss had created, around what would be equal to the third floor. Judging from the number of clones in the crowd, it seemed that most of them were inside with him, with a few outside the building, possibly to try and cut off his escape routes.

He had no doubt that he might have been able to deal with the ones inside the building with him immediately, but he was cautious of the fact that some may have a hidden ability up their sleeves. Fighting in a small room like this was also less than ideal, as they had the upper-hand in numbers. Not to mention that letting loose in a concrete building would most likely send it crashing down. He needed to take this fight outside.

He unleashed a flurry of punches that instantly reduced a nearby wall to rubble, and jumped into the open air, hearing cries of alarm from the clones inside.

Several clones leapt up from smaller buildings nearby, all aiming to intercept the teen. Briefly flashing back to his fight with Mosquito Girl, Genos used his momentum to his advantage, delivering a series of punches that sent the clones across the field. One even rocketed over to the rest of the heroes, although the original Ectoplasm quickly dispersed it before it hit, reverting it back into a glob of spittle.

By some cosmic coincidence or just plain bad luck, the saliva smacked straight into Saitama's blank face, covering him from head to shoulders.

Eraserhead ignored the bald man's muffled cries of indignation and instead focused on Genos' fighting style. This boy was extremely skilled, and it was obvious that he had definitely been involved in harder fights than this. Possibly even fights to the death.

What worried him was the insane efficiency and nature of his attacks. The underground hero was no stranger to efficient use of his abilities. Since his Quirk was not an offensive one, he had to compensate with his overall skill, and thus had to conserve his energy wisely.

Genos did the same, and while it was clear that he was holding back, he was still able to deliver devastating blows onto the clones below. Every move was calculated, and each punch was delivered with the intent to end the fight as quickly as possible. He didn't try to draw it out just for the fun of it, and that was a quality that Aizawa himself respected, even if it was a bit over-the-top.

The nature of the boy's attacks was something to look out for, however. He was sure the other heroes noticed this as well, but all the clones were dispatched in a fashion to either permanently cripple or destroy them outright. While most of that could be chalked up to Genos knowing the clones were not real people, it was still worrying. Vicious actions like that could very well become a liability on the battlefield.

Genos crashed onto the pavement, immediately flipping between the legs of two clones that had jumped in to attack. He blitzed across the faux road and parried a kick with one of his own. Sensors screamed as another approached from behind, aiming for the spot just below the base of his skull. If that hit, it would mean immediate unconsciousness.

If he still had a human body that was. Needless to say, the impact would not have even scratched the armored chassis, not that Genos let him. He made it his own personal challenge to defeat these clones without receiving a single scratch.

Jerking his head to the side, Genos turned into a spinning back-fist, feeling the hardened spittle on the clone's face crack. The limp body tumbled into the clone in front of him, knocking it off balance. With a swift swipe of his armored legs, the cyborg swept it off its feet, and smashed an elbow into its skull, burying it face-first into the concrete.

Before the bodies could even dissolve, Genos quickly retreated, taking note that the remaining dozen clones were now gathered before him. Not allowing the teen any reprieve, they sprang into action, with a few leaping off obstacles and walls in order to build up momentum.

As they neared the cyborg, a few of the clones felt intrigue when Genos decided to stay his ground and cock an armored fist back. No doubt to prepare for an attack that would somehow be able to defeat most, if not all, of the clones.

But Ectoplasm had one more ace up his sleeve. With a quick activation of his Quirk, onlookers were treated to the sight of the rest of the clones suddenly merging and mashing together, much like how lumps of clay mixed to form a larger piece.

With a slight blue glow, the combined clones then morphed into a large clone standing at roughly ten meters tall. Its toothy smile opened up, revealing a cavernous maw. This was one of Ectoplasm's super moves. While it was a fair bit smaller than he could normally make it, the clone was no doubt much more durable and stronger than before, with the cost of some of its speed. Once it had successfully bitten down on its target, it would solidify rapidly, immediately trapping whatever was inside.

To everyone's surprise, Genos made no move dodge, nor did he exhibit any surprise. If anything, he seemed to meet the giant clone's charge head on, bringing both arms up to counter. A cloud of dust enveloped the two as they clashed, sending small quakes up the viewing platform and even toppled a structurally weakened building.

"Ectoplasm!" Aizawa barked, his eyes doing their best to pierce the smokescreen.

Ectoplasm didn't answer straight away, as if he was in deep thought, but then suddenly stiffened. "Impressive."

Before anyone could ask what the hero was talking about, a sudden blast of wind blew the billowing powder away, revealing a sight that had everyone slack-jawed. All Might's smile widened. "I see!"

Genos' armored hands were latched onto the upper and lower jaws of the crouching clone, holding its mouth in place and stopping it from biting down. The clone's eyes widened as it bore down on the cyborg, struggling to loosen the unforgiving grip he had on its face. When the teen didn't even budge, it attempted to lean backwards, only to find that Genos' legs were firmly planted into the floor.

Tremors shook the surrounding area as the two were locked in an unforgiving stalemate. That is, until Genos moved, burying a harsh kick into the clone's midsection. "Hah!"

The impact was felt throughout the building as the giant clone's body actually achieved height and flew airborne, stopping only just before it hit the ceiling when Genos suddenly appeared right above it, his eyes and body slightly glowing orange. Light gleamed off his arms as he cocked his fists back. "Machinegun Blows!"

If Eraserhead were to look back on this moment, he would have compared the sounds of Genos' fists to Bakugo's Quirk letting loose in quick succession. His arms were a blur as they pummeled punishingly into the clone, moving so quickly that it was impossible to see them clearly, even after slowing down the video footage later.

The clone was not even allowed a chance to fight back as armored fists rained down upon it. For a moment, it lay suspended in the air, only moving when its body was hit. It was only on the last, and possibly most powerful, punch that sent it crashing into the concrete below with the force of a meteor impact.

Windows flexed and nearly shattered, while the lights overhead flickered erratically. Dust rained from the ceiling, and the heroes' ears whined in protest to the sudden explosion of pure force that had ended the fight.

Stunned silence filled the room as Genos lightly landed onto one of the few structures still standing. The giant clone slowly started to dissolve into a large puddle as the glow in Genos' body and eyes faded. He turned to face the audience. "Was that adequate?"

Aizawa's eyebrow ticked. The kid didn't even look winded. If anything, he seemed less tense than before, as if the fight had been a simple warm-up rather than one where he had gone up against a pro hero.

Just how much power was he still holding back on? Part of him appreciated the fact that Genos took their earlier talk seriously to tone back on the violence, but if this was him holding back, then he didn't know what to do. At this point, he didn't even think anyone under Rank 10 of the pro heroes in Japan would be able to handle him.

Worse yet, he was sure Saitama was probably worse. Aizawa stole a glance at the mentioned hero, who was still trying to scrape slime off of his clothing. If Genos was supposedly a disciple under this man, then that would mean he could possibly be even stronger than All Might himself. Speaking of All Might, Aizawa couldn't help but feel mildly annoyed when the hero started to laugh, as if the thought that Genos could very well take on top heroes didn't faze him. "That was spectacular, Young Genos! Rarely have I seen such skill in someone so young, and especially in someone with no Quirk! Your world must have fine heroes indeed!"

Genos accepted the praise with a slight nod as Cementoss slowly brought the rest of the group to the totaled field. Without a word, the grey hero set his palms on the floor to melt the rest of the structures that were uncrippled, eventually creating a smooth, unblemished surface once more. It was possibly one of the more versatile Quirks he had seen, Genos mused.

He then gestured over to the tablet in All Might's hand. "Would this suffice in an accurate account of my 'Quirk' for your registry?"

Ectoplasm nodded. "Principal Nezu will see the showcasing of your abilities and take it from there. While we still need some information such as blood type, you are otherwise done."

Genos nodded. "Your Quirk is very impressive. That final move where you fused them together threw me off-guard."

If that was what Genos looked like being caught off-guard, then Eraserhead would have hated to see him absolutely floored. "Genos. I believe we talked about restraint?"

The teen blinked. "I do realize that I may have fought in a way that displeased you, but those were non-living clones. I will never use those power levels on a human, villain or not."

He sighed. "Alright. We'll talk more about this later, but congratulations on making your first steps in registering your 'Quirk'. After we test Saitama, you two are free to head back to your rooms for the night."

Saitama took a quick look out a window, noticing that the moon was already high in the sky. "Are you sure we have time? Genos' test took a while, and I really don't want to miss the breakfast special in the cafeteria tomorrow."

One of Aizawa's customary glares was the only answer he needed.

All Might sympathetically placed a massive hand on Saitama's shoulder. "I understand your worries, but I promise that your test will be quick. Because your power is simply a matter of strength, we do not need to go too much into detail. The reason why Young Genos' test took quite a while is because his abilities are numerous and unique, not to mention the fact that his 'support items' need to be properly explained."

Genos stored that tidbit of knowledge into his memory, while Saitama didn't seem to care much. "How quick are we talking?"

The smiling hero turned to face Cementoss, who nodded and instantly created a large circle in the field. An arena. "I promised that I will have a spar with you, and I intend to uphold it. We have no need to test your speed, since your strength already comes with heightened abilities upon activation, although things like that are uncommon with Emitter type Quirks."

Genos looked upon the arena with interest as he stroked his chin. "Then you intend to gauge Master's abilities with your own? What of your injuries?"

Recovery Girl shuffled forward, her face a mask of disapproval. "His wounds have ultimately healed, since he got one final treatment from me before coming here. But I know that you are feeling mostly exhausted, so I am only going to say this once. If you push yourself too hard in this fight, you are going to regret it."

Saitama swore he saw the man gulping in fear before he gestured over to the arena. "Now then, Saitama, I will explain the rules before we begin."

The prospect of having a spar with someone without the other party trying to kill him was refreshing for the bald hero. Aside from Genos, it was rare to find someone willing to fight him without threatening his immediate demise. Jack-o'-lantern Panic came to mind.

As such, he couldn't help but feel excited about the coming spar. He knew that he was going to have to hold back significantly, especially since All Might was nowhere near Boros' level of strength, but he was willing to see how heroes in this world fought. Maybe he could learn a cool new move in the process.

He stood on a smaller circle on one side of the arena. "Is this good?"

All Might nodded from the other side of the large circle, performing some small stretches "While I did say that we were having a spar, I am going to be holding back as much as I can. Going wild in this gym would only destroy it. Therefore, the goal of this spar is to knock the other out of the circle. You are free to use any technique you see fit; the spar only ends when someone is pushed out-of-bounds."

Saitama's slight disappointment must have shown up on his face, because All Might raised a hand in a placating matter. "I know that this must be less than ideal, but we must make do for the time being. However, I swear that I will ask Principal Nezu for permission to set aside some time to fight in a space more open than this one."

Truth be told, All Might himself was looking forward to fighting a hero from another world. It would be interesting to see how Saitama or even Young Genos operated as heroes.

Plus, it was clear that Saitama was perhaps stronger than he was. Back at the USJ, the Noumu had taken nearly everything he had left in him. His time limit was significantly shortened, and going over 100% was taxing enough, yet it was still not enough to take the Noumu down for good. He had no doubt that he could have defeated the Noumu even a measly year ago, but it was disheartening to see how far he had fallen in that short span of time.

But Saitama didn't seem to struggle at all. If anything, he almost seemed bored at the display of power the Noumu was showing, even in its crazed state.

All Might was not blind: even he could see how dangerous Saitama could potentially be. If a villain as strong as Saitama had appeared in their world, then nobody stood a chance. The pro hero was far past his prime, and while Young Midoriya would definitely grow to become stronger than he had ever been, he doubted One for All would fare well against a man with such overwhelming strength such as Saitama's.

Still, All Might felt no real worry. He knew that his fellow heroes like Eraserhead and Snipe voiced their concerns, but he just could not believe that Saitama was a nefarious villain in disguise. Aside from his plain demeanor, the bald hero was simply lost and even innocent. He had shown no ill-will towards the other heroes, and had only retaliated when they had made the first move on them. They were real pro heroes, through and through, albeit those from another planet.

And that begged the question: just how bad were things in their world? They had once said that villains outnumbered their heroes by a huge margin. He could not imagine such a situation. As the Symbol of Peace, his job was to keep crime low and prove to the good citizens of the world that he was here to protect them. Who was the symbol in their world?

He even hazarded a guess that they did not have one, seeing how dangerous their home was. Or maybe they did, but it was not as effective, as there was just too much danger.

Even All Might knew a hero could only do so much. Before the age of Quirks, governments depended on their military might in order to keep things in order. It was possible that Saitama and Young Genos' world had the same, but it may not have been effective, seeing how heroes this strong would not need such help.

But those questions could wait later. It was getting late, and All Might's own time was slowly ticking down. He flexed and settled into a low crouch, as if he was emulating sumo wrestlers from ages past. "Do you have any final questions, Saitama?"

The man made a thoughtful face. "So all I have to do is to push you out of the ring? No speed tests or fighting those spit clones?"

All Might shook his head. "From what we have seen so far, you are at least as fast as Young Genos here, and even he broke some previous records we have seen from students in his base power level. As for the clones, I doubt they would stand a chance against the man who was able to take down an A-Rank villain with ease. No offense, Ectoplasm."

Saitama nodded slowly, a pensive look still on his face. "Are you sure about this? I don't want to accidentally hurt you."

The large hero laughed, although not unkindly. "Worry not, Saitama! I am more or less healed, and if any of us sustain injuries, I will immediately call for the fight to end."

Saitama shrugged. "All right, if you say so. Ready when you are."

Eraserhead couldn't help but feel a sense of foreboding as All Might and Saitama stared each other down, both waiting for the buzzer to announce the beginning of the spar. "I don't approve of this. We all know how dangerous this could be."

Recovery Girl glanced up at the bandaged hero. "You don't have to tell me twice. But All Might insisted that he wanted to do this."

"But why?"

The elderly woman snorted. "Part of it is the promise he made to Saitama. But apparently he said that it was also a good way to gain trust."

Trust, huh? Eraserhead sighed. He understood what that meant immediately.

Things were tense between both parties. Genos had certain ideologies that they couldn't find a stable ground on, and Saitama…actually, Saitama seemed to be more inclined to go with the flow.

But it was clear that as fellow heroes, their relationship had to start somewhere. That relationship may not start on philosophical debates about the duties of a hero, but on actual hero work. Fighting and learning off each other was a good place to start. He didn't miss how Genos had become more relaxed after fighting the clones. Even if it was extremely subtle, the pro hero knew that the cyborg had felt more at ease after several minutes of fighting than the past few days he had spent with them. He knew some heroes who spent nearly all their time on the battlefield, as they were only ever truly themselves in the face of a good challenge. Pro hero Mirko came to mind.

And as the buzzer rang out overhead, he just hoped that All Might knew what he was doing.

Saitama neatly ducked his head under a quick jab from the large hero, who had immediately blitzed over to him when the buzzer sounded. The speed at which he moved almost impressed the bald hero, even though he was holding back.

All Might smiled that weirdly large smile of his as he pressed the assault, his hands a blur as they reached out to try and grab Saitama.

With a speed that surprised the viewers, Saitama matched the blur with his own as his arms raised up to parry his opponent's. Smacks resounded through the enclosed building as the spar continued.

It was almost funny that a man and a hero like All Might had his hands, which had captured and defeated many villains over the years, slapped aside like a mother deflecting her child from stealing cookies from the cookie jar.

Aizawa's eyes narrowed as he focused in on the bald man. Unlike Genos earlier, whose face was contorted with sheer focus, Saitama's face was almost carefully blank. No matter how close All Might came to grabbing his clothes or knocking him out of the ring, he never flinched once.

Gusts of air blasted across the field as the spar continued, All Might doing his best to gain some kind of upper hand. A swipe to the left was quickly sidestepped, and a palm thrust to Saitama's center was deflected with ease. Other similar attacks were dealt with the same way. The pro hero was going to have to up his game.

Tapping into One for All, All Might increased his power and brought up his arms in a cross formation. "Carolina Smash!"

His hands slashed across Saitama's body, and even if the man had blocked most of the attack, All Might had finally landed a hit. What surprised him was that he didn't even move an inch.

All Might's eyes widened. Even at much less than his normal strength, a Carolina Smash of this magnitude would have thrown a man the same size as Saitama back a few feet at best. His stance was not even positioned to brace against such a blow. Was he keeping himself steady with pure strength alone?

Saitama smiled. "Oh, that's a cool special move! Did you think of the name yourself?"

On the surface, that question sounded a bit demeaning, but All Might knew that the man was simply curious. Hopefully. "Not at all! I created this move after my stay in another country called the United States of America. I dare say all my special moves were named from there!"

The bald man nodded slightly as he pushed back another attack from All Might. "Mind if I try it out?"

Before All Might could get in a word edgewise, Saitama crossed his arms and performed an action that was not dissimilar from American baseball umpires calling safe. "Calorie Smack!"

The force of the move nearly bowled the seven-foot-tall man over as what felt like bars of molten metal slashed across his chest. His eyes widened comically as he was blasted backwards, nearly throwing him out of the ring.

He barely registered small cries of alarm from his fellow heroes as he managed to get solid footing against the concrete.

"Crap, are you alright?" Saitama asked, a worried look crossing over his face. "I tried not to hit you too hard, but doing that move made my arms move kinda fast so I couldn't help it."

All Might blinked once before letting out a boisterous laugh. "Do not worry, Saitama! That power was quite something to behold, so it threw me off guard for a second!"

The pro hero settled back into a battle-ready stance, brushing off the slight sting in his chest. "However, you did not manage to get me out of the ring!"

Pumping a bit more power into his swings now, All Might let loose a barrage of jabs and grapples that kicked up a storm of dust. The only thing faster than his attacks were the dodges from the bald man, who left slight afterimages in his wake.

From the sidelines, Eraserhead frowned. "He doesn't seem to be taking this too seriously."

Genos glanced up at him from writing in a notebook that he had magically procured out of nowhere, reminding the pro hero of a certain problem child he had in his classroom. "I assure you, Master fighting seriously is a rare and dangerous occurrence. Nothing and no one would be able to withstand his strength."

Aizawa tried to ignore how sure Genos sounded and how unbelievably ominous that statement was, as if the teen had just casually announced that he was in possession of a nuke that could go off at any moment. "The purpose of this spar is to see his technique and at least some of his powers. If he is just dodging and copying moves, we will not be able to get an accurate description for his Quirk registry."

Genos scowled slightly. "Are you saying that Master is insulting his opponent?"

"No. I'm saying that Saitama's just fooling around when we all know that he can at least push All Might back."

Although both Genos' and Aizawa's voices were lowered, All Might couldn't help but overhear. And he was sure that Saitama had heard them as well, even if his face betrayed no emotion.

Aizawa was right, though. While All Might certainly did not feel insulted that Saitama was not using his normal strength in this duel, he couldn't help but feel miffed about the lack of Saitama's offensive moves. The previous "Calorie Smack" was a write-off in All Might's books, seeing how he was just copying a move.

There was also the issue of Saitama's skills. He had no doubt that the bald hero was much stronger than he was. Even in his prime, All Might doubted that he would have been able to land a single hit on him. But aside from being, as his predecessor would have put it, "built like a brick shithouse," All Might had yet to see any sort of technique from Saitama.

Every hero had a certain fighting technique. He himself created his own style of combat from US boxing and Japanese martial arts. Pro hero Gunhead excelled in armed combat, and built up his fighting style accordingly. Even long-range Quirk users like Midnight had moves that complimented their abilities for maximum damage.

But he had yet to see anything like that from Saitama. Sure, he was fast and strong enough to completely obliterate the Noumu and break through solid brick walls with ease, but that was the extent of it. No form of martial arts seemed to be prevalent in the way he had fought, and even his punches were somewhat random and thrown around without any form to them.

The pro hero stopped his assault and stepped backwards. Saitama lowered his arms and tilted his head quizzically. "Why'd you stop? Are we done?"

All Might shook his head. "I just had a question for you, if you would be so kind to give me an honest answer."

A pause. All Might took that as an affirmation. "I am not asking this to sound rude, but have you had any formal combat training?"

Saitama blinked. What kind of question was that? "Like martial arts?"

The blonde hero nodded. "From looking at how Young Genos had fought Ectoplasm's clones, it is clear to see that he had either created his own combat technique or learned it from an outside source. However, I have yet to see any from you, both in our spar and from the fight at the USJ."

Saitama hummed thoughtfully, scratching his head. "I mean, I did have one of the heroes in my world try to teach me some martial arts, but he kind of annoyed me and Genos too much cuz he was trying to get us to join his dojo. His martial art's name was weird too. Fist of Water Polo or something."

All Might nodded. "So, it is safe to assume that you do not currently practice any form of martial arts?"

Saitama shrugged. "I never saw the point of it. When I was training to be a hero, all I had to do was beat monsters. It didn't really matter how I did it, so I just learned how to punch things."

"But what if you feel the need to dodge or counter an attack? Martial arts could quite possibly be of value to you."

The bald hero frowned. "I mean, I can dodge just fine. And countering isn't really something I need to do all the time. Everything usually dies in one punch anyways."

All Might ignored how unintentionally morbid that last statement was. "I see. That is something we may need to catalogue in your hero registry. However, I would recommend learning some basic fighting techniques in the near future, Saitama. If you wish to pass off as a hero, you must have some basic knowledge in combat training. Your reaction speed and agility are astounding, but any experienced hero will know when someone is an amateur in martial arts."

That kind of sounded dumb to Saitama, but he could kind of get where he was coming from. It was true that he never learned how to really fight. Once he started training and got stronger, all the monsters that he had fought were always taken down in one hit. As such, the appeal of learning some flashy moves were lost on him, even if they looked cool.

His strength carried him through his hero duties well enough so far, but he had to be extra careful here. From what he had seen, this world was pretty populated, so causing unnecessary damage while fighting a mons —villain was a bad idea. He still felt bad about completely demolishing City B while fighting that giant naked guy a few months ago. There was a reason he lived in City Z, and it was not only because of the low rent.

All Might cricked his neck. "Simply food-for-thought, Saitama. I have no doubt that you are on the side of the heroes, and everyone will treat you accordingly. If you wish, I can ask some heroes I know to set aside some time for you to learn some basic techniques."

Although it sounded annoying, Saitama nodded. After all, all he had to do was to copy some moves and be done with it. Piece of cake.

All Might settled back into a fighting pose. "Alright, shall we get back to it?"

Saitama followed suit with a slight bend of his knees.

With the blonde hero's words still fresh on his mind, Saitama decided to finally go on the offensive. It was getting kind of late, and he knew he had to fight back at some point, or the other heroes might get annoyed. Especially Erasingface.

In a blink of an eye, All Might witnessed the hero in his bright yellow outfit literally disappear, with the only indication of him being there being the small craters in the ground where his feet were.

Instincts screamed as All Might crouched low to the ground, feeling the air ruffle his hair as Saitama's arm swiped overhead from directly behind him.

All Might wasted no time in grabbing the bald hero's arm and gripping it tightly, ensuring that he had no way to escape his grasp. Then, he started to spin rapidly, kicking up a small tornado of dust. "Oklahoma Smash!"

With a mighty heave, All Might shunted Saitama across the length of the arena. He only felt mildly surprised when the bald man twisted his body midair and dug his feet into the floor, digging up a furrow as the kinetic energy pushed him to the edge of the boundary.

Saitama steadied himself and gingerly stepped out of the new canals in the floor. He watched as the gashes filled as Cementoss quickly fixed them, leaving behind a smooth surface once more.

He stopped an incoming fist in its tracks with an open palm, the impact creating a thunderclap that reverberated through the building. Muscles strained as All Might attempted to push Saitama out of the ring, only to be violently tossed to the side as Saitama flung his arm high into the air.

Now completely open, the pro hero could only witness as both Saitama's hands shoved him away, sending him tumbling across the arena.

Thankfully, the attack had missed the old wound on his side, but it was still enough to knock the wind out of him. Spittle left his mouth as he gasped, tasting dust in his mouth as he crashed against the field.

As All Might rolled against the ground, he desperately attempted to find something to grab or to gain a foothold on anything. But the force of Saitama's offense was enough to stop any such attempt, and he could only watch with mild frustration as his body cleared the edge of the circle.

While he had no doubt that there was no way he was going to win this spar, All Might couldn't help but feel a pang of despair. It was over as soon as Saitama went on the offensive. He had lost.

He brought his arms up to guard his head as the ground grew closer, bracing himself for the impact that never came.

With a sudden jolt, the hero's momentum stopped completely as he felt something grab at his forearm, stopping him from tumbling across the gym even further.

Saitama looked down at All Might's face, effortlessly holding the large hero in place. "I guess I win."

Silence fell across Gym Gamma as the two heroes stared at each other, one not even having broken a sweat, and the other gasping for air.

Gulping once, All Might felt his smile come back onto his face, graciously letting himself be pulled up by the significantly smaller man. "Yes, you have!"

The buzzer rang out overhead, and the other heroes started to make their way to the two men. "Even as a mock battle, I have never pushed myself as far as I have done in many years. Your reaction time is incredible, and I am hard-pressed to think of any way to beat you!"

"Don't say that as if that's a good thing, All Might," Aizawa grumbled, "He still has a ways to go if he wants to fool everyone into thinking that he's a hero from any legitimate organization."

"I have question about that," Genos stated, making his way to his Master's side, "Which hero school will you say we will be from? UA seems too high profile, as anyone would know from looking at previous alumni."

Aizawa shrugged. "Who knows? Principal Nezu told me that he knew people in America, so I assume we're going to pretend you are from there. Just don't get caught by anyone speaking English to you, or we'll be in trouble."

Saitama's brow crinkled. There's more than one language in this world? Why does this place have to be so complicated?

All Might heard rather than saw Recovery Girl striding up to him, repeatedly poking him in the leg with her cane. "You better not have anything worse than some bruises, All Might. If you're nursing a broken bone again, you are going to be sorry."

The blonde hero gave her a thumbs up. "No need to fear! Saitama was gracious enough to stop me in my tracks before I could get any more roughed up. These bruises will be an easy fix with your Quirk."

Recovery Girl rolled her eyes as All Might bent down on his knees. Even in his crouched position, he still towered over the elderly hero. Saitama and Genos watched with mild fascination as her lips extended nearly a full foot from her face and pressed against All Might's cheek, leaving behind a smooch mark and a glowing green effect.

Out of curiosity, Genos silently activated the biometric function in his eyes, assessing her power at work as All Might's bruises were suddenly wiped away, leaving behind perfectly normal skin in its wake.

It seemed that her Quirk sped up the body's natural immune and recovery systems to an astonishing degree. It seemed to work based on the body's energy, as the display showed that All Might lost vitality just a tiny bit. He had no doubt that the pro hero was feeling a little tired after that.

In just a few short seconds, the wounds were gone, and All Might was as normal as he was at the beginning of the brawl. To onlookers, he was perfectly healthy and whole again.

On the outside, that was.

Genos's eyes narrowed as his HUD flashed red, throwing up data on a devastating old wound on the blonde hero's left side, marking a lack of a stomach and a destroyed respiratory system. Judging from the damage he was able to x-ray, it was a miracle All Might was still alive, seeing how the initial point of impact was so close to his heart.

Even now, Genos could tell that the hero was struggling to maintain his posture. There seemed to be blood in his throat, and his one remaining lung was nearly choking him as it heaved, desperate for more air to fuel his large body.

But there was something else afoot, and possibly even more interesting than All Might's current physique.

According to the data, it seemed as if All Might's Quirk was constantly active. Energy filled his entire body from head to toe, and it never stopped, coiling around him and thrumming with power. But there was something wrong with his Quirk.

It was struggling. Even as the seconds ticked by, his energy levels consistently dropped, sometimes even by full percentages.

There was no reason why the pro hero's Quirk would still be active. And Genos knew it was somewhat unnatural, especially when he compared it to the Quirks of other hero's like Eraserhead or Cementoss.

For the mutant type hero, Genos was able to discern that his Quirk only became active when he touched the ground and purposefully turned it on, thus allowing him to mold the terrain however he wished.

Eraserhead's Quirk was similar, in that the Quirk only came into effect when he wanted it to, flooding his eyes with his power, giving it that characteristic red gleam. But he never had it on all the time, since that would inevitably lead to certain health issues.

But All Might was a unique case. It was almost as if the Quirk didn't even belong in his body. And the wounds were making it worse. By keeping the Quirk active, he was creating even more damage. Soon, the Quirk itself would become unusable.

The question was why the pro hero was doing this. It would be a simple thing to just deactivate the Quirk and let the body recover, but All Might still kept it on. There were no threats around the immediate vicinity, and the brawl he had with Master was long over. No, he was keeping the Quirk on because he wanted to.

Genos had no doubt that All Might knew this. After all, the only person who knew their own body best was themselves.

Suicidal tendencies were crossed off, as he detected no abnormal serotonin or dopamine levels. Active threats in the area were also crossed off, as there was no human being within 300 meters of the property. And it being simply the nature of his Quirk was crossed off, as that would have killed him a long time ago.

Maybe there was something else afoot. There was still much he did not know about this world, and some research on this world's version of the Internet would be a good place to start. Quirks that damaged the user's body, either intentionally or unintentionally, were an interesting topic, and he didn't doubt there would be sufficient data to satiate his curiosity.

Genos snapped out of his musings when Eraserhead cleared his throat. "All right, that's enough excitement for the day. I'll be taking Saitama and Genos back to their quarters for the night. The data we collected today would hopefully be enough for the principal to create a convincing record of your existence, so you don't have to keep on your toes about being mistaken for vigilantes much longer."

All Might stifled a cough, which didn't go unnoticed by the cyborg. "Good! It would be a shame for more misunderstandings to occur in the future. I must be going then as well. I do have to prepare for classes involving Saitama and Young Genos, after all!"

Saitama nodded before doing a small double-take. "What?"

Genos was similarly surprised. "You mean…"

Aizawa sighed. "Against my explicit wishes, you will be integrated into the UA hero course as temporary staff. I told Principal Nezu that it would be better for you two to keep a low profile, but he insisted that nowhere is safer to blend in than in UA. It also allows us to keep a better eye on you, since we can't be with you 24/7."

"But I don't know anything about teaching," Saitama insisted, "I barely finished high school, I can't be responsible for educating a bunch of kids. I already have Genos as a disciple anyways."

Aizawa rolled his eyes imperceptibly. "Of course, you are not going to be real teachers. You're just going to help out in hero exercises with All Might and occasionally me. It would give a lot of people some relief if you were guarded by the number one hero. Understood?"

Genos grudgingly accepted the conditions. In all honesty, it would do them good to assist with the heroes of the future. Aside from learning more about this world's culture, he could also figure out how Quirks worked better, and get some valuable information in return.

Resigned to the fact that he was having to attend school once more, Saitama sighed. "When do we start, then?"

All Might laughed. "Tomorrow morning! Come to my office at no later than 6:00 AM! We have a busy week ahead of us!"

Saitama groaned. He just wanted to go home already.

[-]

Izuku yawned widely as he trudged through the doors to his classroom. Even this early in the morning, his fellow classmates clamored inside, overshadowing the desperate cries of Tenya telling them to get ready for class.

Though it was a bright and otherwise beautiful morning, Izuku was feeling simultaneously exhausted and stressed out.

Getting help with his opening ceremony speech from Kaachan was a…unique experience. It was almost no help at all, with Kaachan insisting he put certain words in the speech that would not be accepted well by the UA staff. The yelling didn't help either, with the explosive teen constantly screaming at him to 'put more effort into it,' which, in turn, caused Auntie Mitsuki to barge into the room to tell him to shut up.

But there were some silver linings to the verbal abuse he had to witness. Kaachan made some helpful points in letting his own voice being heard instead of just making a general speech. It was something that he had to make sure was unique to him and no one else.

Plus, All Might wanted him to proclaim to the world about his existence, and this opening speech was a good starting point.

If only he wasn't so nervous.

Another factor in his low energy levels this morning was the topic of Saitama and Genos, which had been something that was on his mind for quite a while now. Except things seemed to get a bit more confusing.

In the span of what seemed like just overnight, Izuku was finally able to get some information on the identities of the two heroes.

Apparently, they were heroes from America, and were sent here on a diplomatic mission to Japan to build relations. They had received their hero licenses from a small school in Montana, and preferred to perform undercover. He assumed it was to catch villains by surprise when it turned out the normal civilians crossing the street were in fact very capable and extremely powerful heroes.

There was some other basic information that Izuku was able to find off the Internet, but something still felt off.

First off, why was it so hard to find such trivial information like this in the first place? It was almost as if their hero registry was made overnight. It was almost as if the two didn't even exist as of yesterday.

Another thing that didn't click was the nature of their mission. There was no news that he could find that explained their sudden visit, nor their appearance at the USJ when villains were attacking. Not to mention how hostile the UA staff had been towards them, as if they had just met that day.

But if that was the case, why were they allowed to attend UA classes, as if nothing was wrong? They could be vigilantes, but they had an active hero license on the US Hero registry.

Izuku almost tore his notebook pages writing so quickly in them. By the time it was ready for him to go to bed, he had filled out several pages' worth on the two hero's abilities, origins, nationalities, and other theories that he could think of with a sleep addled brain.

He slumped into his seat after a brief greeting to Katsuki, who tutted at him when he saw his face. "You look like shit."

Izuku huffed. "Couldn't sleep much. I had a lot of things on my mind."

The blonde teen smirked. "Well, get used to it, Deku. We still got a full 2 weeks before the festival. If I hear you giving up, I'm gonna take back the responsibility for the speech."

Any further conversation was halted with the introduction of Ochaco, who had burst into the classroom with a cheerful greeting to the rest of the class. "Hey Deku! Oh, hi also, Bakugo! What do you guys think we're going to do today? If it's anything like what Hagakure said, then I'm super pumped!"

Izuku blinked. "Uh…Just normal class stuff maybe? Did Hagakure say we're doing something different?"

Ochaco plopped into Sero's empty seat, as the Tape Quirk user was off chatting with Mina and the others. "So apparently, Hagakure got here really early in the morning to drop off some late assignments at the teacher's lounge, when she saw Mr. Saitama and Mr. Genos with All Might! She said that they were going over some class activity with them and they might be helping out!"

That was news to him. Izuku couldn't help but feel excited. Maybe they were going to hear about their experiences in the hero field? Or maybe how hero work was like in the US. Then again, if they were with All Might, it might have to do something about combat training. The possibilities were endless.

Katsuki gave off a feral grin. "I hope we get to see how they fight. If I'm able to take them down, then I'm one more step to being the number one hero."

Izuku and Ochaco laughed nervously. "I don't think that's going to be possible…"

The doors to the classroom slid open, revealing the still-bandaged form of their homeroom teacher. "Everyone in your seats."

Ochaco quickly jumped out of the seat. "I'll talk to you after class, Deku!"

With a dainty wave and a slight blush from Izuku, the bubbly teen and the rest of the class speedily sat in their seats, watching as Aizawa shambled over to the podium.

To the classroom's collective surprise, All Might himself walked in, along with Saitama and Genos, with the former looking like he was going to pass out from sleep deprivation. "I am in your homeroom!"

Aizawa cleared his throat. "I can see you are all confused. Before you start asking me questions, yes, Iida, I can see that you have one, let me explain some things first."

He gestured over to the hero duo, both of whom seated themselves on the same seats they were in the day before. "Saitama and Demon Cyborg are here on a diplomatic mission to Japan from America. They're with UA for the foreseeable future, and will now be assisting with the school curriculum to the best of their abilities. Because they are pro heroes, they are also able to guide you at any point should you need help. If you need permission to use the gym equipment or other activities, you are free to ask them for permission. Any questions?"

Yaoyorozu raised her hand. "But Mr. Aizawa, what is All Might doing here? We don't have Foundational Hero Studies until tomorrow."

All Might stood, beaming a smile at the teen. "Plans change, Young Yaoyorozu! I was planning on doing our hero training activity tomorrow, but Saitama and Young Genos still needs to get situated in UA, and will therefore be busy. So, we have decided to move it up to today!"

Tenya half-stood up from his chair. "What will activity be? And why do you need Saitama and Demon Cyborg today?"

"I am glad you asked!" All Might's face suddenly took on a more serious look. "As you know, the USJ Incident caused a lot of ripples within society, and many are asking UA how they plan on keeping the students safe. We have since then implemented a massive overhaul to security measures to make sure something like this does not happen again, but we decided that we needed something else."

Izuku's eyes widened. He couldn't possibly mean…

"Therefore, out activity today will be a joint exercise between class I-A and our two guests! The goal is simple. The hero team must steal some intel from the villain team before the time runs out! This will give you all valuable information on how villains operate, and teach you how to deal with them. I have already asked if it was okay for the villain team to play as the villains in this activity, and they voiced their approval. Of course, since this is just an exercise, there would be no excessive force used. The heroes will lose when they are incapacitated, and the villains will lose if the heroes manage to steal the intel."

Mineta raised a shaking hand. "W-Wait, since you already asked the villain team, then that means we're the…"

All Might's grin widened even further, if that was even possible. "Correct! The hero team will be all of class 1-A versus the villain team, Saitama and Demon Cyborg!"

Through the shocked silence, Saitama snored.

Howdy folks, I'm back. Kept you waiting, huh?

Yea, sorry about the wait again. This past year was pretty crazy, with work and COVID and all that, so I haven't been able to write as much as I wanted to.

I apologize for the long ass updates, but real life takes priority, so there's not much I can do about that other than working little by little on this story.

For everyone's information, I am not planning on extending this story to where the manga or anime is at this moment, which is around Season 5. I am actually planning on wrapping this story up during the Overhaul Arc, with some major twists in the plot to keep it more interesting.

Sorry if you guys wanted me to keep this going until to where it is now, but I'm gonna be honest, it's going to be impossible for me to do that. There's just so much happening in the story, and with how strong Saitama and Genos is, I really don't feel that it's going to be much of a challenge for anybody.

Anyways, I hope you guys liked this chapter! Yay, things are finally getting explained, at least on the pro hero side. I hope this part of the story felt okay for you readers. You would not believe how many rough drafts I threw out before settling on this prompt. If it felt unnatural and stilted, trust me, it could have been a lot worse. Some of those rough drafts were enough to kill the mood entirely.

And yes, I made Izuku and Katsuki's relationship not fucked up. I'm a sucker for stories that make out Katsuki to be a genuine friend to Izuku, like darkfire1220's Viridescent. Go check it out if you haven't; it's a great read.

Next part is gonna be a doozy, but I plan breaking it up with smaller chapters, maybe like 6000 words per chapter. I think part of the problem why it takes so long for me to pump these out is because of the length. As of writing this, this single chapter is 17,713 words. Never doing that again, Jesus.

I also just found out recently that I have a TV Tropes page. Yeah, I was shocked to find out too. I feel bad for the poor sap that had to write that and wait for any update to my story. Hope I don't make their job too miserable. Big thank you to whoever made the page! I really appreciate that you guys enjoy my story, even if it takes me centuries to make.

Also also, I am planning on changing my story name. Unforeseen Circumstances is a bit too boring of a title, and I hate myself for being lazy enough to think that it was any good. Comes with the pen name, I guess.

But I plan on changing it soon to Punching Things Isn't a Quirk. Somewhat similar to my old and scrapped Fullmetal Alchemist x RWBY fanfic. But I like it, so look out for it being changed in the near future. Don't worry, I'll put in the description of the story of what it used to be called so people won't get confused.

And with that, I bid you all good day. I will do my best to pump out some chapters soon, seeing how I'm a little less busy this summer than the previous year, which was absolute hell.

Goodbye for now!
