Chapter 1: A new life

MISSION IN THE ONE PUNCH MAN WORLD

That was supposed to be just another day for Saitama. Any other day where he woke up, got into a fight or any crisis that involves villains, humanity and doomsday, end it with a punch or maybe more, depending on how strong the enemies are, go back home and wash his gloves, as well to receive either zero gratitude or even accusations of him being a cheater.

Honestly, all he had ever done is using his power to save the day and almost no one believes him. Not that he can blame them, but people everyone can at least believe his method of training. But still, he cannot blame them. That day, Saitama and his so-called cyborg apprentice, Genos, were engaging another smart-ass lunatic that built a machine that according to him, can generate a portal to different dimension and he might as well planned to unleash whatever the hell was sleeping within. Subduing the lunatic and his lackeys were easy enough, but deactivating the already activated machine is the tough part.

While Genos was trying to deactivating the machine manually, Saitama just had to decide to just punch the machine away into oblivion. The result was, due to malfunction a black hole was generated and it sucks everything unfortunate and close enough into the darkness. Saitama who destroyed the machine first-handed of course was the first one to be pulled in.

"SENSEI!" shouted Genos as he quickly grabbed into some structures that seemed can hold long enough. And his other arm reached out just to be able to grab Saitama's hand in a nick of time.

Saitama was relieved that his companion managed to grab him as he saw the 'lunatic' as well as his lackeys were screaming in terror as their bodies disappeared into the hole. "Whoa, you saved me, man!" said Saitama as he let out a sigh of relief. "Don't let go, 'right?!"

"Hnngghh….!" Genos grunted as he tried to pull Saitama towards him, using his strength to fight against the air current. "Hang in there… Sensei… Just a bit more….!" Said Genos as he kept pulling, but the force from the black hole was really strong due to how close the distance the two heroes with the hole.

Saitama's eyes widened as he saw that the structures Genos was holding on could not hold their ground and would soon crumbled, then after contemplating few seconds, the bald hero let out a small smile for a moment then he said, "Um… Y'know what? I guess you can let go, now" with laid-back tone.

"What!? What are you saying!? I'm not letting you go!" said Genos with desperate tone. But at the same time, he could not deny that the structures he held on couldn't last longer and the black hole before them would not disappear any sooner.

"Cut the melodrama, Genos" said Saitama with straight face. "This is not some romance where a couple were desperately clinging on their lives. Well, we WERE clinging for our lives now, but still!" said Saitama as his faced hardened, "You've gotta lemme go or we'd both die! You know what's the best choice!"

"But I still want to have more missions with you… And I still want to learn more from you…." Genos said as he realised the fact. He had to let go or he will also sucked into the black hole. "You saved me countless times, you even put up with my selfishness and my quest of vengeance! I haven't repaid you yet!"

Genos was truly indebted to Saitama. At first he wanted to learn the origin of Saitama unmatched strength so he can be strong enough to defeat the crazy cyborg that took everything away from him in his past, but his self-proclaim teacher not only willing to take him in, he also taught him many things, but he also helped him quell his hatred. Truthfully, after Genos was finished with his quest of vengeance, or rather his hatred and his past, the cyborg doesn't care anymore about Saitama's power origin. Even if he still wanted to be stronger, it was for the sake of becoming a hero like Saitama. If he was still fully human, Genos would be crying right now.

"Geez, you're really too serious for you own good…" said Saitama as he snickered. "You don't need to learn anymore. Hell, you're not even my disciple to begin with!" Saitama declared as he slammed his fist onto Genos' arm that was holding him.

Genos eyes widened as his arm got crushed into pieces from Saitama's hit. He wanted to use his remaining arm to grab Saitama again, but his reasoning got the better of him. Genos only gapped with a face filled with shock, fear, and slight betrayal as he saw his teacher got further away into the black hole. "I'll leave things in your care now, BUDDY!" was Saitama's parting words as he smiled and put gesture of someone saying goodbye.

Few seconds after Saitama had disappeared into the darkness, the hole disappeared as well. Leaving the cyborg on the rubbles as his body fell on knees. "SAITAMA!" Genos shouted as his voice was heard loud that day by other heroes around.

Dark… That was Saitama's first thought as the portal connecting him and the world got closed before him. The man tried to move, but he could not feel anything at all since his inside a vacuum space. Saitama also realised that there was no air to breath either. It seemed that holding breath can do the trick for now but Saitama aware as well that he could not keep this up forever. He had to do something quick before he died from suffocation.

''Shit… I really can't go where I want to…'' thought Saitama as his body kept floating mindlessly in the space.

He can't feel that his legs or hands touched or made any contact with anything, and his chest started to hurt. It looks like that his lungs had reached their limits. It has already quite some time since he got sucked into the oblivion. As his lungs had gone over his limit, Saitama finally gave up and just let his body floating somewhere as he waited until his consciousness fade away. Not to mention, this space inflicted quite pain on his body, as if the space itself tried to destroy his body. However, just right when Saitama had closed his eyes in resignation, suddenly a sense of comfort washed over him. The man opened his eyes slightly, to feel that he was going to sleep once again. His body was no longer in pain, he somehow can breathe normally again, but the toll put on his body from the damage he took from the space took a better of him.

The last thing he saw was a large glowing balls that resembles a pair of yellow reptilian eyes, belong to a giant figure looming over him. The last things he heard before he finally succumbed into unconsciousness were,

"It's been a while…"

"…Never thought you're going to showed up…"

"Hmph… entertain me more…"

"…do something about that little pricks of my world…Baldy."

"Wha… What?! Damn… So sleepy…" thought Saitama as he finally passed out.

SOMEWHERE ON A DIRT ROAD

Laying on the ground was Saitama as he slowly got up to his feet as he dusted off his clothing, and his cape, "Well, at least I have something with me while I'm in heaven…?" He said to himself as he looked around and noticed there was a carriage nearby as he stared at it blankly. "Maybe I should reconsider what I just said. Hmm…Well I suppose I can ask where I am at." He finishes saying to himself as he dashes towards the carriage, but before he could say anything some sort of danger beast appears out of the ground?!

"I-It's an Earth Dragon?!" Shouted one of the people on the carriage.

"Oh?" Saitama said to himself as he looks at it, suddenly its arm is sliced off shocking Saitama as he stares at the cloaked figure as he slides off his cloak to reveal a young teen, with Brown hair and green eyes, as Saitama looks at him blankly. "Hmm…my turn? Hehehe." He says evily as he dashes to the dragon and punches it with ease as it splatters everywhere as everyone is looking at him shocked with eyebrows twitching. "Again, One punch…? Even here?! GOD DAMN IT!" he shouts as they all look t him confused, but a bit happy at the same time. The young man decided to approach him.

"He took it out…With one punch?!" One of the carriage men said.

"Uh, hey there dude, thanks for the help. I could have kind handled it on my own hehe." The boy says scratching the back of his neck, as Saitama looks at him blankly as the boy decides to break the awkward silence, "Um, anyways, hey there the name is Tatsumi! What's your name?" Tatsumi asks the Caped baldy as Saitama stares at him.

"Saitama, hero for fun and profit. Put 'er there!" He reaches out to the boy as he sweat drops but shakes his hand anyways. "Anyways…Can you tell me where I am?" He asks.

"Well you're on the outskirts of the Imperial Capital. I am going there to make a profit for my village! What about you Saitama-San?" Tatsumi asks curious why this baldy here is in this situation.

"Uh well…I kinda popped up here, and don't know where to go." He said simply as he scratches his ear, making the younger man sweat drop as he sighs.

"Well, how about you follow me there. I will take you, and show you around the capital? How does that sound?" Tatsumi asks.

"Uh sure. Thanks." Saitama said as they begin walking off before the men stopped them to thank them for protecting them and all.

INSIDE THE CAPITAL

"There are limits to how many we can hire! If you get it, scram, you damned brat!" Shouted the man who threw him out.

"Wow this place is huge." Saitama says to himself as he is waiting outside the doors of the barracks as Tatsumi is thrown out. "Oh? What happened?" He asks.

"Tch, these bastards think I don't have the qualifications to join the Capital's army!" Tatsumi shouted quite mad.

"…Oh…" Was all the Caped Baldy said, since ya know…He isn't good with these situations. They were about to leave off until…

"Hi!" Someone said as Tatsumi looks up and Saitama looks as they are both confused. "Something seems to be troubling you , young man. Want a lady to lend you a hand?" The woman asks Tatsumi, as she notices Tatsumi blushing looking at her bust. "What's wrong with you?" she asks as he doesn't answer and she continues, "Drawn by dreams of making it in the capital, you came all the way from the country?" She says shocking Tatsumi.

"How did you know that?" Tatsumi asks surprised.

"I knew at once. If you've lived in the capital long enough, you can identify outsiders. Anyway… I knew a quick way to get hired for government services." The woman says as Tatsumi is just surprised.

"Seriously?" Tatsumi says.

"Want to know how?" She asks.

"Yes, yes!" tatsumi says bowing as Saitama stares blankly with his arms crossed not amused as he thinks, 'The hell is up with this kid?'.

The woman blushes and smiles saying, "Then treat a lady to a meal!" both men face fault.

"Well I will be going. I have somewhat better things to do I guess. See ya around tatsumi, have fun on yer date." Saitama says as he walks off waving as the woman looks at him as she narrows her eyes, but…this man…Something odd about him…his power. She continues to observe him for a minute as Tatsumi is waving with a smile on his face.

WITH SAITAMA

Walking around the capital, most of the people are either giggling or staring at the bald man walking in the middle of the streets in a goofy outfit as he is looking around with a blank face, "Maybe I should've went with them…I am hungry." He is walking around as guards pass by as they glance at the man, as they glance at eachother and nod as they start walking towards the caped baldy.

"You there, stop where you are." The guards come up to him as Saitama turns around with his confused blank face. "Who are you? Where are you from? And what's with the get up?!" One guard asks as Saitama tilts his head. "I believe I asked you a question, so answer before we force you to!" they point their guns at him.

'What is wrong with these guys? Jeez, all I am trying to do is make my way around here, trying to find a supermarket and this is what I get?' Saitama thinks as he sighs, "My name is Saitama, hero for fun and profit. Anything else needed to be said?" He stares at the guards blankly, which they take it the wrong way,

"Well, how about we show you how to properly speak to your superiors, rat!" the guard shouts as he shoots his gun, but they still see the bald man standing. What's going on?! "What the hell?! I swore I shot this bastard! Tch…KILL HIM!" the three guards begin firing as Saitama dodges with ease as he is between them three as his eyes are shadowed, shocking the guard, as suddenly they notice their guns are gone?! "What the-UGH!" his neck was chopped lightly as Saitama lays the guard on the ground, as the other two glare at him.

"Why YOU! TCH! DIE YOU TRASH!" Before the second guard could move, he was also put down with a neck chop, as Saitama also lays him on the ground lightly, the third guard is terrified as Saitama glares at him as the guard runs away.

"You will pay you bastard! Just you wait!" He took off as Saitama just sighs.

"What did I even do to deserve this? Eh, like it matters. Now…Back to looking for a market!" Saitama smiles a bit as he goes looking around he place as far away the woman from earlier, now holding a brown bag full of money in her hand watched the whole thing, as she shuts her eyes and walks away.

LATER THAT NIGHT WALKING ALONG A BRIDGE

Saitama was walking along the bridge as he notices a familiar face all alone as he smiles a bit, "Yo Tatsumi!" He runs over to the young teen as he looks up noticing the boy was sitting alone, as he looked up seeing his new friend as he smiles, but looks down.

"Oh, hey Saitama. So…Did you make your way around the Capital?" Tatsumi asks.

"Yeah. It was quite a fun experience. Could have been better, to be honest" Saitama says as he scratches his chin remembering what happened earlier with the guards.

"Oh, well atleast you had a good time I suppose…I got robbed." Tatsumi says as he looks at Saitama.

"Ouch. That sucks." Saitama says casually.

"HOW CAN YOU SAY THAT SO CASUALLY?!" Tatsumi shouts anime style at the Caped Baldy.

"Anyways, well I am gonna go now, I am hungry still so, bye." Saitama says as he walks off, but he feels his cape being gripped, as he looks at the corner of his eye down at the teen.

"SERIOUSLY?! YOU ARE ALREADY LEAVING?!" Tatsumi says not impressed with lack of communication from the hero.

"Eh, let go. You will tear my cape, and I don't have any money to buy a new one so…" Saitama says as Tatsumi rolls his eyes.

"Look, I need your help Saitama. I don't have any money, and I need to get some for some place to live atleast. Please help me." Tatsumi says as Saitama face palms.

"You are seriously asking help from somebody in the same situation?" He says as he has a deadpan face.

"I am serious…" Tatsumi says, but suddenly a carriage stops in front of them.

"Again, my lady?" a guard of the carriage asks.

"You know I can't help it. It's my nature." She says as she steps out of it, and walks to Tatsumi as she stares at him, "If you have nowhere to sleep, would you like to stay at my home?" She asks making Tatsumi skeptical of this situation as he looks up to see nothing to where his friend was just at as dash marks surround the space forming a figure shape of Saitama as it shows that's where he was before he just now left.

"That bald bastard…" Tatsumi says to himself as he looks back at the girl. "Well uh…I don't have any money." He says to her.

"You wouldn't be sleeping here if you did, would you?" She says to him as the guards of the carriage walk up.

"Lady Aria can't ignore people like you. You should accept her generosity." One of the guards say.

"What would you like to do?" Aria asks.

Tatsumi blushes, "Well…I guess it's better than sleeping outside…" he says as Aria smiles blushing.

"It's settled, then!" Aria says as they leave off.

WITH THE CAPED BALDY

Laying on a roof of a pub building, Saitama glances at the stars as he thinks of everything that has happened in the past till now, he has never had any great battles that pushed him beyond his limits what-so-ever. It's like he was just unstoppable, hell even the "denominator" of the universe as Saitama called him (Lol) wasn't even a warm up for him.

"Sigh…I hope this world is something better, giving me a lot more expectations. I need to make money soon before I go ape shit." He says to himself as he turns over and shuts his eyes. "Better luck tomorrow." He finishes as he drifts off into a deep sleep.

3 MONTHS PASS AS SAITAMA HAS MADE A LIVING IN THE CAPITAL AS A MARKET WORKER

"Sigh…Even three months later, nothing interesting has come to this place." Saitama says o himself as he is walking to his small home with some bags in his hand. Something that has caught his interest has been the rumors of the assassin group "Night Raid, huh?" He says as he stares at the wanted posters, as he observes them, and he tilts his head looking at the Akame wanted poster, "Wow, these are so neatly drawn." He says to himself as he walks away with his blue track suit, for some reason he has in this world too.

Lately, Night Raid has been assassinating a lot of nobles, and commanders of the Capital. Saitama wasn't in the least concerned of his safety. He never held his guard up, he has been living his normal life as ever. He usually always encounters some of those "asshole knights" as he calls them, because they look like knights to him from a certain video game he has played in his past life. He wonders if anything new will come of it in this world ever since he has lived here. Hell, the Caped baldy even wonders at times, if whether his younger "Acquaintance" tatsumi made it somewhere within the capital after their last confrontation. Well, little does he know…

JOGGING DOWN THE STREETS OF THE CAPITAL FOR HIS MORNING ROUTINE

Saitama has currently been jogging during his time in the Capital too, though it bothers guards at times, that they just want to gut the guy. Most just don't care, seeing he would outrun them in seconds, in this case, there are a couple that are tired of it.

"NOW!" One of the guards shout as suddenly a couple guards block the path way of the Caped Baldy's run way. "So baldy, how about we stop you here, because what you're doing has been bothering the people of the Capital, and we want to put you to Justice to stop this." The guard says as Saitama jogs in place staring at the guard with a blank face, which starts to anger the guards.

"Seriously? Justice?" Saitama says as he is reminded of someone who use to shout that word…specifically a good acq- no…A friend, Mumen Rider. "Well may I pass? I see nothing wrong with some exercise, it looks like something you need." Saitama says as the guard's eyebrows twitch.

"Bastard! KILL HIM!" They pull out their weapons and charge.

"Seriously..? Again…? How many times do I have to tell you guys, you need to train more!" Saitama says while sighing.

5 MINUTES LATER…

Saitama is currently walking off as the guards are beaten into the ground, possibly some are dead. They are badly beaten as Saitama is casually walking away, "That was so boring, even Jack-O-Lantern guy was a better match." He says while going home.

AT THE PALACE

"What happened?" Budo shouted, unable to believe what he just heard.

"We don't know his name, nor did we get a good look at his face, only his bald head, but his power…" The imperial soldier trailed off.

"To think some imbecile could overpower 20 of us in a mere couple of seconds…" another soldier said.

"This is indeed troublesome news." Budo said cupping his chin in thought. "Can you describe his power? What did it look like?" he asked.

"Well…the thing is, we didn't even get to see it…We were all knocked down before we could eve see him move." One soldier said.

Budo was more than shocked. Just the fact that a mere man's strength that rivals his own was a very scary thought.

ONE WEEK LATER

Now after the incident, Saitama continued his lifestyle of letting the world pass him by. Although he hated the way the Capital functioned with its corrupt nature, he didn't want any part of the fighting, he just wanted to live a normal life like it has been these last couple of months. Soon he actually made a plan, that if he ever has the chance, he will rip the Prime Ministers throat apart for making Cabbage so damn expensive. Thought came as he was walking along the quiet streets that went to the main gate out to the forest on the way to his home.

Saitama slowly walking home in his blue track suit, he lost track of time a long time ago as he passed by a familiar trees and landscape of the forest that lead to his home. He always found it sort of relaxing when he peacefully walks around, he would always be reminded of the time him and his ex partner Genos were running to eliminate the House of Evolution. He smiled a bit, remembering his partner. Suddenly…He stopped in his tracks as he looks to the left corner of his eyes as he puts his hood over his head, he felt it, it was killing intent heading towards him, it was major, but to him it was not so much a big deal.

He jumped onto a tree suddenly he dodged with ease, a blast of energy shot passed him as he lands back on the ground as his hood shadows his eyes, but he sensed the presence of a figure a couple 100 meters away.

"He's good." She admitted, "But he's surrounded now."

All around Saitama, figures came out of the woods surrounding him from the shadows. A huge armored figure, a purple haired woman, a animistic looking blonde, a brown hair kid who he found familiar, and finally a young girl with black hair and red eyes wielding a Katana. In a manor of seconds they surrounded Saitama and he said, "Night Raid, huh?" He said bored of the situation under his hood.

"That's right." The swordsmen said.

The girl with the katana looked at him with emotionless eyes like his, "Saitama, Night Raid has orders to eliminate you."

Ok everyone, hope you all enjoyed this first chapter! I hope you all look forward to the next, because I will do my best to make it a good one, so please look forward to the next one. Thank you.

Keep it cool, keep it classy, always and forever.

Ja Ne.
