A/N: Just a little something I whipped up in a few hours, mostly just copied storyline with some slight differences and quite a bit of OOC. It'd be my first OPM fantic, so there's that too. I kinda ran out of steam for my Re:Zero one.. but it's still in progress.

Lemme know whatcha think! Chapter 1 will probably be out within 2 days! o7

The Journey Through S Class

Prologue: The Hero Exam

"Ha, finally done with all the tests." Saitama stood in the Z city HA building locker room, wearing nothing but a blue speedo. "No just to wait for the results." He said, looking rather proud of himself, content with how he performed. He wasn't measuring, but his physical displays were rather… ahem, IMPRESSIVE, compared to all of the other tryouts.

Then he noticed Genos coming towards him from elsewhere, and in his happy attitude he was more than ready to talk with the 'disciple' of his. "Aah, you're done too?" He asked, and received a nod. "Yes." Though, with Genos being robotic, he did want to ask. "Eeh, is there even a point to you doing the physical tests? Can't you just give them the data on your specs? Eh, whatever. So how was it?"

As Genos registered his sensei's words, he replied in his all too known way. The.. Genos way. "Both the written and physical tests were far too simple." Dissing on thing he sees as beneath him. "Right? Is that really all there is to becoming a hero?" "It seems so. Also, we should be getting our results soon. 70 points is a passing grade. The written test was so easy that anyone could easily get full points on it. That just leaves the fitness test, which for us should not have posted any problems."

ONE HOUR LATER

"I got 100 points." Genos says as if anything else was laughable. "Seriously?" Saitama asked, him sitting down on the bench nearby. Now he was wearing his Oppai hoodie and jeans, losing his entire 'strong' appearance. "yes."

"It says I'm certified as a class s hero." He says in much the same tone. "Class S? What's that?" Of course, Saitama had no clue what anything other than 'you passed' and 'you failed' meant in regards to the hero association, however if he's in it… he could probably pay a little more attention. At least it'd beat being bored all day.

"I am sure these ranking mean little. How did you do, Master?" of course he was quick to say what he believed. All in all, it was much the same for the both of them. "Eh?" He pulls out his paper, fully displaying the page. "Oh, it says I'm…" "S class, yet… oh, there's a note at the bottom." Genos points out. "...Amai Mask is not pleased, however allows it?" Genos questioned in a genuinely curious tone. "Who's Kawaii Mast?"

Genos began scanning the name and utilized his built in internet connection to search it, and instantly found that the man was a superstar idol, and A class rank 1. "It seems he's some sort of popular figurehead of the association." Genos deduces, wishing to show his master his findings but lacked the ability to project them into a hologram. "Anyways, we're both S class. But… my score only says 71?" Saitama read that correctly, his physical was 50/50, yet his written was 21/50. "That's very strange… Ahh. It was buried, but on their site it says that those with strength rivalling at least a whole military division are assigned to S class. So… they recognized your greatness, Sensei."

Having a never-ending pool of positivity for his master, be completely threw out his words from earlier about the written test being easy. *Biing* "Mr. Genos, Mr. Saitama, there will be a seminar for successful candidates at 4:00PM. Please come to lecture hall #3." a voice came over the intercom, it seemed now that they were the only two made heroes that day. From this facility, at least.

"You heard him, let's go." "Yes!"

ELSEWHERE

"We're terribly sorry about the sudden request earlier, accompanied with the finding of the cyborg we've been searching for." "While it was annoying… that small clip of his… performance, was rather amusing. And… he physically beats all the meat heads within the S class. Think of it as no more than an… experiment. And as for the cyborg… I agree with your decision in bumping his rank to S class as well."

"Saitama and Genos, eh…"

LECTURE HALL #3

"First, congratulations on passing." It was an empty room that appeared to be very similar to a classroom, with A class rank 38 Snek standing at the front, looking over both Genos and Saitama, who both seemed entirely uninterested in whatever the man was going to say.

"Both of you performed incredibly well, but don't get all cocky about it either. To preserve your rank, and to keep a dignified impression of the Hero Association, you musn't act idiotically, not only are your own careers on the line, but so is the name of the association. Do I make myself clear?"

Beyond some more details about how they would be registered on the heroes roster on the website, it was rather dull. And unknown to the two, Snek really did want to chew them out… but, after seeing Saitama's physicals first hand, he decided not to.

THE NEXT DAY

"Hero registry?" Standing at the bottom of a massive gorge, Saitama and Genos sold a fair distance apart from each other. Saitama wore his hero costume, and Genos was still wearing… what he usually wears. He was holding a phone as well, maybe to actually be able to show Saitama the things he searched by himself.

"Yes, we're both S class heroes. I am ranked 17th, and you are ranked 18th… we're dead last in that regard. However, in comparison, we're in the highest class there is to be in, so we're a part of their… elite, if you would. And right now, we're simply listed as Genos and Saitama, but as we perform more heroic acts, we acquire hero names." He says.

"Hero names? What're those?" While not desne, Saitama was entirely out of the loop. While he probably wouldn't much care unless they called him something like.. say, 'Caped Baldy' for example, he'd probably be fine with it.

"I believe they are like nicknames that capture a hero's characteristics. For example, I might be Blond Cyborg." He says. "So if that is how it works, then I'd be called… Caped… Baldy….." Fuck.

"Aside from being ranked by ability, you can also be ranked by popularity. There are some heroes that have fan clubs." He says. Saitama is a bit taken by that statement, and begins to fantasize one of his few desires being true, while Genos pockets his phone. "Well, no one cares about that." And he completely contradicts his master's beliefs….

SECONDS LATER

"Thank you for accepting my unreasonable request today." Genos calls to the more distant Saitama, who was still walking a bit farther away "yeah, well I did agree to making you my disciple. Eeh.. is here good?" He turns around to Genos, who nods. "So we're just having a practice bout, right? Not fighting for real?" Saitama asks. "Yes, that's what I have in mind. However, do you mind if I record the match?"

Saitama scratched his head, then responded. "I don't exactly understand why, but sure. But if my clothes are burnt off or something, you gotta scrub it." He agrees. "Alright. I want you to go all out, so I too will give it my all." He says, then starts to fume with heat. The dispersion channels now live and orange with heat on his chest and back, arms and legs. Everywhere, really. He takes a low stance. "please Grant my request." He says, and then long rocket trails come out of the back of his shoulders, exploding into a rather magnificent fiery display as he shoots forward at the speed of a bullet.

He reeled one foot back as he propelled forwards at Saitama at speed rivalling a Railgun shot, arcs of electricity looking much like lightning expelling off of him as he attacks his master, his foot hitting where his chest would be… yet wasn't. He instantly reacts and turns himself around, using his palm as a thruster to negate the speed and also pushing himself forwards yet again, and starts spinning around as he attempted a flying roundhouse kick at the man, again hitting perfectly, if only the target didn't move so quickly.

With some amazing acrobatics he shoots himself around his master in an attempt to throw him off, and then went right above him and put almost everything he hand on bringing his leg down onto the man's position. With the impact the ground shattered in all directions for at least twenty meters and a small electric wave was dispersed, as if it were a miniature EMP blast. Yet he knew this wouldn't get him, as he simply jumped into the air.

But he anticipated this, and charged a high powered plasma blast that could almost be called a laser and fired it with pinpoint accuracy, it lighting up the entire area and hitting the edge of the ridge.

"That was close, my clothes could have got burnt up again." Saitama gingerly landed behind him where the large burn mark laid on the ground, something caused by the backflow of the plasma.

Genos was hoping that would have hit, yet he knew… it was nowhere near close. "Ghaa! I need more speed!" He exclaims, placing his palms on the ground as he then doubled in brightness, his reactor running at full tilt now. He started levitating as if literally counteracting gravity, so much so that his shoulder jets were far more active just to keep him from shooting up into the sky. And then, he disappeared from sight.

With only a millisecond to react, Saitama does the same, mimicking the cyborg's actions until he was pushed into the air, and them began having to dodge the onslaught of robotic punches of fury. Behind Saitama was an increasingly long line of medium sized craters that seemingly defied the sense that he was hitting him, at which point he paused… to see nobody there. 'He's gone. Have I been chasing his after image the entire time?' he wondered, and then immediately focused on the rest of the gorge.

It took a while, but eventually he found him running g away at a somewhat slow place, and then shot off to him in an instant. He landed in front of him and prepared an attack that wouldn't allow for such a miscalculation to occur… a full power, cone Incinerate. "Incinerate." He says, and with that, the entire extended array of nozzles and ports on his linked arms roared with power, exploding forth a giant mass of plasma and liquid fire.

'I got him this time. Master will have to take me more seriously now…' though, he was instantly proved wrong by a few Pat's on the back of his neck. "Okay I win." Saitama says, though Genos strikes to where he was, just making him jump back. "Master…" "Eh?" "Have you forgotten the rules of the bout? Dodge any attack you are able to dodge, take it seriously and no fooling around." He had to repeat the rules.

"Do not hold back, and… keep fighting until I am no longer able to fight." 'Even Master Saitama cannot explain… the secret to his power. This bout may give me insight into it.'

"Show me no mercy." He finishes, as a golden glow radiated off of him. Now he put the very last of what he could into his body, and readied… just to see Saitama move faster than he ever thought could have been possible, appearing before him. He kicked, yet it ripped right through a still after image, as then

.. he felt it. DEATH.

It was coming his way. He turned around just to see that gloved red fist coming at his head at a speed that would not only decapitate him, but entirely flatten his skull down to the atomic scale in thickness. Yet, it didn't hit. Instead, what would be cubic miles worth of air rushed past him and went forward, as his master lost his serious expression and gained a happy smile. "I'm starving. Time for lunch. Let's grab some Udon noodles." He says, simply walking off in a weird fashion. "Okay…" Genos was simply shutting down all of his systems, and was almost ready to cut the video… however, helt a change in the environment behind him. It was screaming at him, to turn around. And so, he did.

'I am prepared to do anything to get stronger. However… I can't picture myself ever getting to Master's power…. Not at all.' He zoomed in past the gorge's new ravine, the utterly massive hole carved into it by simple air by his master's punch, yet… he zoomed in on the mountain past it, and noted… the ever similar crevice that simply cut the top of it in two. 'master Saitama .. is on a level beyond anything ever imaginable.' he finished, and then the video cuts.

And in the mere three hours of this video being posted on to both Genos' and Saitama's hero pages, five million views were had… for each.

LATER & ELSEWHERE

"So that's where they are? Well enough, I'll just give them a.. proper welcoming. If that video is anything to go by…" he trails, not finishing his sentence. 'Far superior to the Meatheads of the S class.' he thought.

WITH SAI-BRO

"I'm very glad you like Udon." Saitama says, simply waiting for a waiter to come to them. "Yes, I'm not very picky." Genos replies. "Well, I'm also pretty low on funds right now, hopefully this hero business will sort that though." He says, then spies something on the menu that he rather enjoyed the look of. "Eh, how about another match, Genos?" He pointed off to the food challenge, one that if one of them won, they'd be able to come out with more cash than they spent. So, why not try a battle of who has the bigger stomach?

A LITTLE LATER

Ignoring the other patrons comments of stupefied awe, it was fun. Saitama had more than filled himself as his Udon bowl was nearly empty, though there was still some left… he failed. And Genos? He was finishing off the broth and all, probably with more than enough room to spare. But don't mind his stomach, he probably burns everything he eats with his plasma, which arguably could literally be his blood. "Is that it?" He asks, setting the bowl down with a *Clack*

"Man, you're awesome." the stuffed one says, and at the same time the sliding door to the restaurant opened and in walked a certain A class hero… Amai Mask.

He easily made his way through the crowd to the two new heroes, calling their names as he approached. "You two must be Genos and Saitama. I'm Amai Mask, A class rank 1" he introduced himself. "I'd like to talk to you. The both of you." He said, seemingly not carrying any emotions at all. "Amai Mask… so I had your name wrong earlier." Saitama comments.

He motioned for the both of them to rise, while placing five ten thousand yen bills on their counter, in a motion of laying their bill. A kind gesture, at least. They followed him outside, completely ignoring the fawning fans that were quite noisy throughout.

Outside it was rather quiet and peaceful, the two standing across from the other one, he seemed to be friendly at the moment. "Welcome to the S class, the both of you." He says. "Genos, yours was an expected promotion, apparently they've been tracking you for a while." He says. "As for you, Saitama… I originally was against your suggested placement, having simply taken a look at your score, yet… when I was again pestered to look at your physical capabilities, I was honestly impressed. You're far stronger than all the Meatheads in the S class. I'm confident that they would… enjoy your presence the most." Obviously joking about that last part, he started laughing. "Anyways, this is a welcoming gift from me to the both of you, considering you aah, apparently live in the same place. Aah, and that video was quite something. It's exactly what you both need." He said genuinely, and then stopped his cheerful behavior.

"A professional hero must be a beautiful symbol of Justice. This is especially true of the S class. That is my philosophy. I hope that you both uphold it better than the others…" he says, and then straightens himself out. "Anyways, I've come all this way simply to greet you. Please, do enjoy your nights." He says, and then vanishes.

LATER

"So that's Amai Mask." Saitama says, scratching behind his ear as he looks at the little box he gave them. "yes. He came off far more… friendlier than I had expected, Master."

"Eeh? He put money in here." Saitama had already opened it, and was already thinking greatly of the dude. With so much, he could pay for rent for the next year without worrying! At least, that's where his mind was dwelling.

"Ah, master?" "Eh?" "I will be back later." He says. "ok." And with this, the two S class heroes separate, going their own ways in the night.
