Reborn As Saitama In MHA

Back home, Hiroto was back alone in his room as he contemplated what had transpired throughout the day. Standing in front of the mirror, he stared at his own bald head.

'I simply said to my parents that I probably had a strength quirk. Technically that's correct. I definitely feel stronger, a lot more significantly stronger.' Hiroto clenched his fists, feeling the air around it slightly vibrate under the pressure.

'Mom and dad should be asleep by now. I can sneak out and test what my current strength is. I need to make sure that no one sees me, or I could get in trouble.' Hiroto thought, as he opened the window of his room and leaped out onto the ground with no trouble from the upper floor.

'If I remember, there should be an empty park around the corner there.' Hiroto thought, as he then wanted to test out his current speed.

"Let's try a moderate speed," Hiroto said, and the moment he started to run, he already appeared at the park. The spot where he stood only left an afterimage and disappeared after a second.

"Not bad, quite fast." Hiroto stood around the empty and dark park as he approached a tree. "I probably shouldn't do anything too serious. I feel like if I did, there wouldn't be a city anymore…"

Clenching his fist, instead of punching the tree, Hiroto instead used one hand to grab its bark, and with a slight tug, the entire tree came free from the ground. Root and all.

"... I bȧrėly put in any effort." Hiroto muttered as he stuck the tree back into the ground, albeit, leaning at an awkward angle.

Looking up into the sky, he scratched the back of his bald head and thought for a second, before bending his knees and jumping.

Ripping through the air, Hiroto launched himself high up into the sky high above the city and the clouds before he slowly started to fall back down.

"Wait, I can control the strength of my jump so that I don't destroy the ground… but what about when I land? I can't control how hard I fall, can I?" Hiroto had a thoughtful expression as he cupped his chin with his hand as he fell, thinking to himself.

"Ah, got it!" Hiroto said as he banged his fist on his palm. Looking at the approaching ground, Hiroto opened his mouth and slightly blew, which caused a powerful gust of air to leave his mouth, slowing his descent.

However, what he failed to notice was that all the trees in the area of the park had been blown away from the center of where he landed due to his breath. But that's something Hiroto will just have to worry about another day… maybe…

[Time Skip]

A few more years flew by, as Hiroto still continued the same training regimen each and every day. However, ever since he became stronger he never felt that tired or sore ever again.

Although he got his powers, Hiroto never fought with anyone just yet. Well, whenever he did try to do so it was all in self-defense since people who weren't registered as heroes aren't allowed to use their quirks unless it's in self-defense.

Currently, at age 14, Hiroto was with his parents in a car as they drove towards their new home, in Musutafu. His father wanted to expand the business and found a big warehouse that was on sale in the city and wanted to convert it into a giant gym were normal civilians and people with quirks can come to train.

His father has a strength quirk, that allowed him to have strength higher than multiple bodybuilders put together, whereas his mother had a quirk that allowed her to have a stronger and tougher body. Meaning if someone with normal strength were to punch or hit her, she wouldn't be fazed by it.

Watching the passing buildings, Hiroto thought back to the time he first faced someone who tried to rob him on his way back from school. The man had some weird quirk that allowed him to turn his fingernails into weapons.

Well, after being attacked, Hiroto retaliated and it ended as you would've imagined. The mugger gave some long speech about wanting his money and why he turned to a villain but Hiroto never paid attention, as all he could think about was the new game that was being released.

When the man realized the boy in front of him wasn't paying attention he wanted to smack Hiroto's head, but one light punch to the stomach and it was lights out for him.

"Are you excited about going to this new school? I heard that U.A. High School boasts the best Heroics education in Japan!" His mother said from the front seat as his father drove to their new home.

Hiroto currently had a blank expression on his face. Ever since his quirk manifested, his facial features changed as well depending on his mood. (A/N: How Saitama normally looks when he isn't serious)

"I don't really care. I want to try being a hero for fun. But, you can't do that legally." Hiroto said indifferently.

His dad spoke up, "Well, don't you worry. From what I heard, U.A. High school is the best there is, and once you graduate you'll become a full-fledged hero! Although your mother and I would've preferred you to study to get a normal job, we don't want you to limit yourself and do something boring for the rest of your life. Who knows, maybe this whole hero business could keep you entertained for once."

'I wonder how strong All Might is. With all the weird types of quirks and abilities out there, they should prove to give more of a challenge than your common thugs.' Hiroto thought to himself, as they pulled up to their new home.

"Alright, we're here! The moving company already moved all our furniture in, so everything's already furnished." His dad said as the family got out of their car.

"Hey mom, dad, I'm gonna take a walk around the block," Hiroto said as he started to walk off in a random direction.

"Okay, just be careful honey! We'll call you when it's time for dinner." His mother shouted after him as they got settled in their new house.

Taking out his phone, Hiroto began looking up where the nearest manga stores were.

"Hmm, a bit into the city. Oh well, I've got time." Hiroto said as he made his way towards where his map told him. "I wonder if they have a sale on. Mom and dad are quite stingy with my allowance."

"Anyway, this villain… Isn't this the one all might pursued earlier?" Man A said.

"All might! Seriously?! Do you think he will come?!" Man B shouted in excitement, rousing the crowd's anticipation.

From behind the crowd, a small boy with green hair passed the group of people and stuck his head out to see what the commotion was about. He saw a big blob of mud currently in between some destroyed stores, attacking its surroundings. Inside of it, was a boy with blonde spiky hair, struggling to rid himself of the mud with great pain.

Covering his mouth, the young boy with green hair sweated profusely. 'This is my fault…! And whoever is caught can't move!! This mud is Elusive! They are just waiting for a hero with an advantageous "quirk" to come!!"

As the boy was anxiously thinking, the trapped blonde boy's eyes connected with that of the green-haired boy, showing his pleading eyes.

A moment later, the green-haired boy recklessly rushed forward past the crowd towards the mud creature as the heroes quickly yelled for him to stop.

As this was happening, Hiroto stared at his phone, never once looking up as he was still looking for where the shop was. He came to a stop when he almost bumped into very skinny man with sharp, angular features and long limbs.

"Ah, sorry, I need to go through," Hiroto said as he walked past the stunned man, who quickly reacted.

"No, you can't go through! There's a villain there and he's got a boy captured!" The man said, but his words reached deaf ears and Hiroto continued forward.

"Stop… you…!!" The voice of the mud monster mixed with the blonde-haired boy shouted at the green-haired boy who tried to pry him free.

"Say, do you know where the manga store is? It says that on the map it should be around here somewhere, but I can't find it."

Interrupting them, an indifferent looking bald boy wearing a yellow hoody with jeans stood next to the mud monster as he asked the green-haired boy. No one could believe their eyes as they saw another boy approach the monster. Is this a trend nowadays? And this boy was bald as well.

"You!! Move!!" The mud monster shouted as he slammed his mud-covered hand towards Hiroto and the green-haired boy.

At that moment, a large muscular hand appeared before them, as a largely built man covered in steam spoke up.

"You have managed to persuade me… that my morals are not just there fo-"

"Buzz off." A plain voice interrupted him.

*BAM*

Without wasting a second, Hiroto punched towards the mud creature, as a loud resounding punch reverberated throughout the entire city. Having been interrupted, the tall man, All Might, just stood there awkwardly as he held onto the two boys wearing school uniforms.

"I just wanted to ask a question, jeez," Hiroto said as he walked away. His body was being blocked by All Might's massive frame, so others didn't see what happened. However, All Might and the two boys clearly saw what happened, before the two had fainted.

The crowd behind them stayed silent for a moment before they erupted into cheers.

"So cool, so this is it!!"

"It's All Might's power! With one hit, he defeated the villain!"

As the crowd was cheering, All Might turned and looked towards where that bald boy went, only to find him kneeling next to a pile of rubble.

"Ahhh! I can't believe that it was destroyed!" Hiroto cried out as he picked up the remains of the manga store.
