Why one punch man!?

Wow, mortal... your death was pretty pathetic." R.O.B. says to me as I scowl in fury.

"Dude, I don't wanna talk about it. Why the hell would you reincarnate me into Mha quirkless? I couldn't even make it to my 13th birthday before getting killed by a villain!" I can barely contain my anger as Rob deadpans at me.

"*sigh* I thought you would make it work somehow. Guess not... how about this. I will send you to a random world with a royal bloodline of the viltrumite race. In this random world, all you will have to do is survive to your 17th birthday." R.O.B rubs his chin as he stares at me.

Shaking my head, I consider his offer. What's the worst world I can end up in? Once I hit 17, I should be good to go. Viltrumites are pretty strong, after all.

"Hmmm, deal! Make me look like megumi fushiguro from jujutsu kaisen, though! I wanna be unique!" I voice my answer as robs face gains a creepy smile.

"Very well. I shall send you off into the body of an orphan. You will start off as a 4 year old, and you will have the basic knowledge of this world. No future knowledge, though. Only things that are relevant before cannon." R.O.B then waves his hands as my surroundings change.

The darkness of the void dissappears as I'm placed inside the body of a tiny megumi fushiguro.

Shaking my head at a sensory overload due to inheriting my memories, I smile as someone calls out to me.

"Megumi-Chan, come along and eat breakfast with the rest of us~" a motherly voice calls out as I rush over happily.

Life was fine for the first 10 years. I stayed in the orphanage, never being adopted due to my efforts to scare off attempting families. I already have my sights set. Once I become a viltrumite, I will become rich by any means necessary, so I'm in no rush for a family.

I'm a high-school student, and I'm quite popular with the opposite gender. Albeit unintentionally, megumi is quite good looking, so it's only natural, but the people in this world are weird.

Walking through the halls of school with a massive feeling of boredom. I sigh as girls giggle and whisper behind my back.

As the final bell rings, I waste no time and immediately leave the building. Heading back to the orphanage.

In this world, there are heroes. Though, the heroes are Hella inconsistent and only appear every once in a while to kill a monster and ride a wave of clout. Once that clout goes away, they disappear.

That doesn't narrow down what world I am currently in because I can recall a bunch of worlds from my past 2 lives that have had monsters and heroes. I've never personally run into a monster, but I know from the blurry videos that they are pretty scary.

I've already embraced death twice, so dying isn't one of my fears. The only thing I fear is going back to Rob's teasing and mockery. And spiders... but that's for another time.

"3 more years..." I mutter under my breath as I move around crowds of people. I'm in city Z. A city that has suddenly seen a massive emergence of monsters. The inconsistent heroes haven't really tried to save anyone, so people live in a constant state of fear.

As I'm deep in thought, I hear a loud crash as I leap in shock. "What the hell?" Turning to the rising dust behind me, I get a glimpse of a massive silhouette as I don't even bother to wait for the dust to clear and immediately high tail it out of there.

I can hear the monsters heavy footsteps as it chases after me growling. My heart begins pumping as I feel it catching up to me.

'Shit shit shit! This can't be happening. I need more time! No!' I yell in panic as just before the monster can grab me a black haired, average looking dude. Flys past me and kick the monster away.

"Hey, you okay?" His voice is monotone, but I can tell he genuinely cared as I shake my head before flinching as the monster gets up with a growl.

As I examine my savior realization hits me like a gun shot as I realize what world I'm in "mother fucking one punch man..." I mutter as the man I recognize as pre bald saitama tilts his head at me in confusion.

"Eh, what's one punch ma-" I don't let him finish his sentence as I run away. Not looking back as I know saitama will win the fight. He is the one favored by this universe after all.

***

After that day I took numerous martial art classes. I didn't do Any physical exercises since I will get super strength almost unrivaled even in this worlds standards once I turn 17 so lifting weights would be a waste of time.

I've got the top belts with karate and judo and I'm practicing Taekwondo. I'm currently 16 and turn 17 in a week's time so I'm trying to get Taekwondo down before I awaken.

The hero association formed a year after I met saitama. The previous absent clout chasing heros immediately flocked to the hero association and surprisingly crime rate skyrocketed when they did that. The emergence of monsters and mad scientists making themselves monsters seem to have doubled with the addition of heros. So every city is like an entire battle ground with constant fights.

City z is now a ghost town as the monsters have taken it over completely. Forcing all civilians and heros out as city z is practically there home.

Currently, though, I'm sparring with my sensei as we stand across from each other in a basic combat stance.

Dashing forward, I go on the offensive as I chop my hand out only for it to get parried as my senses guide my hand to the mat under us.

In a bout of agility, I flip with the flow of his parry going for an overhead flip, which he catches before spinning around and slamming me into the mat.

Feeling the air rush out of my lungs, I have no time to rest as I roll away from two consecutive stomps that would have ended the fight.

Just before his third stomp attempt can land, I kickflip up planting both my feet in his gut, sending him away and getting myself off the ground.

Meeting his eyes, a silent agreement happens between the two of us as we dash towards each other, aiming to end the fight.

Angling my body in a way that makes me look like I'm going to go right, I dash left once he bites and goes for a rib kick that he blocks with his knee.

"Oh." I mutter as he spins in a way that in my first life would be considered not physically possible as he throws me into a padded wall before closing the distance and punching out. His fist stops just before it reaches me.

Smiling down at me, my sensei helps me stand straight as he laughs "hahaha your still too green to beat me eh fushiguro? You're still too slow to react, and you overthink. Instead of fighting, you spend time running through your thoughts. In a life or death situation, you should never do that." My sensei advises me as I nod at his reasoning.

'Man... why one puch man?' I contemplate as sensei chews my ear out.
