A/N: This is the MHA story I published on WebNovel. I stopped updating it months ago, but thought I should post it here for more people to read. I would say this story has a different vibe from Accidental Gamer Hero. I had more childish fun writing this and there are quite a few memes and references in this, so don't take it too seriously.

My name is Kurogami Yasuo. I live in a world where roughly 80% of the world's population are born with superpowers, also known as quirks.

Because of such a phenomenon, there are many who have used their quirks for the purposes of evil. They are known as villains.

At the same time, there are also those who stand up to these people and use their quirks to stop these villains. They are known as heroes.

Although heroism was seen as criminal vigilantism in the past, nowadays, being a pro-hero is a legitimate and respectable career. It is no longer an uncommon sight to see heroes chasing down villains and engaging them in epic battles.

When I was five, I awakened my quirk...

"Let's compete to see who can climb the tree the fastest!" Takeo challenged.

It was completely unfair because Takeo had just recently awakened his quirk that let him climb on surfaces like a spider. And now he was looking for any chance to show off his quirk.

"Don't wanna~."

"You will just cheat."

The rest of the boys rejected, already having experienced losing to Takeo in such challenges many times. They were five years old, but they weren't stupid enough to keep doing the same thing over and over again and expect different results.

"Okay." However, I was the stubborn sort of person who would do exactly that.

"Ho ho, looks like Yasuo is the only one brave enough to accept my challenge!" Takeo grinned.

"Oi, you'll lose, Yasuo."

"Yeah, Takeo cheats, don't 'cha know?"

The rest of the boys tried to dissuade me, but I just smiled in response. "He can't always win! This time, I'm going Plus Ultra!"

Takeo smirked, "You think you're All Might? Hahah, watch this!"

The five year old boy ran at the tree, but before he crashed into the tree, Takeo jumped on the trunk letting his palms stick on to the surface. A moment after regaining his balance, Takeo climbed up the tree using his palms and knees, looking like a cockroach.

It only took ten seconds for the boy to reach the top, "Hahah! No one can beat me!"

"Shut up you damn spider!"

"Yeah you cockroach!"

The rest of the boys jeered before one of them pat me on the shoulder, "Yasuo, you have to beat him!"

I smiled confidently, "Leave it to me guys! Takeo, today is the end of your rain!"

"Huh? Is it raining?"

"Rain means... I don't know I heard it on the TV." I answered, "It doesn't matter! Here I go!"

I ran at the tree and tried running up the first few steps. As expected, gravity took hold of me and the initial momentum of my run started fading. However, before I fell, I lunged forward to catch the grip on the trunk. I started climbing up as quickly as I could, but it was quickly apparent to me that I couldn't climb as fast as Takeo did.

"Damnit! Plus Ultra!" I yelled out as I leaped off the trunk and reached towards a nearby branch - roughly 4 feet away. Of course, there was no way I could have reached that branch so I started falling to the ground instead.

"Oh no, Yasuo!" I heard my friends cry out as I was about to hit the ground.

'AHHHH HELP! I'M FALLING! OH NO IT'S GOING TO HURT SO MUCH! MOM IS GOING TO BE SO PISSED! …Why am I falling for so long?'

As I wondered why it took so long for me to actually hit the floor, I opened up my eyes that had been tightly shut for fear of the pain, I realized that I was still in the air... floating.

"Woah! Yasuo! You're floating!"

"Yasuo got his quirk!"

My friends exclaimed, even Takeo who was at the top of the tree looked shocked silent.

"I got a quirk? I got a quirk! Yes! I can float just like dad!" I cheered, before my quirk stopped working and I fell to the ground, albeit with a lot less force as I had previously stopped falling just a few feet from the ground.

After the discovery of my newly awakened quirk, I quickly ran home to tell my parents.

"Mom, dad! I got my quirk!" I yelled out as I ran into the house.

My mom looked pleasantly surprised as she came out of the kitchen, "Yasu-chan, you did!? That's amazing!"

I nodded vigorously, "Yep! Look, look!"

I jumped up, and strangely enough I instinctively knew how to repeat what I had just done at the playground. As I reached the apex of my jump, I froze in mid air, shrugging off gravity's pull on my small body as I levitated in the air.

"See! I can float like dad!"

My mom beamed in happiness before she started tearing up, "That's amazing, Yasu-chan! I'm so proud of you!"

I frowned at the sight of my mom's tears, "Mom, what's wrong, why are you crying? Are you sad?"

"No, no, mom isn't sad. This is tears of joy. I'm crying because I'm so happy." My mom quickly wiped away her tears, not wanting to show her son such a look.

Seeing my mom tearing up made my heart twist. I didn't want mom to cry, even if she said she it was happy crying. When I cry, mom hugs me and makes me feel all better. I have to hug mom so her tears won't come out anymore.

The next thing I knew, while I was still floating in mid air, I started moving towards mom before hugging her with my open arms.

"There, there, it's okay. I'm here." I said, remembering what mom usually told me when she hugged me when I was crying.

"Y-Yasu-chan, you flew!" My mom exclaimed in surprise.

"Huh?" I asked in confusion, wondering what she was surprised about.

"It's not just floating, you can fly!"

"Wow, I can fly!?"

My mom called my dad who was still at work to tell him the good news, and my dad took a half day off from work to celebrate with me.

When I showed him my quirk, he was even happier than mom.

"Amazing! Your quirk is better than mine!" He had happily cried out when he saw me floating around the house.

I learned that my father's quirk allowed him to hover a few feet in the air, but that was it. He couldn't move when floating like I could.

"Yasu-chan inherited my quirk! And it's better than mine! I'm so proud!" My dad cried out, and just like mom tears of joy started coming out of his eyes.

A few days later, my parents discovered that flight was not my only ability. In fact, flight was not my quirk at all, unlike what they had initially thought.

It all happened when I grabbed a fist full of candy from the jar my mom had hidden high up on the shelves from me. But with my new quirk, I could float up the shelf and take as much candy as I wanted.

"Yasu-chan! What did I say about flying at home?" My mom's voice sounded out from behind me, and in my shock at getting caught, I dropped the handful of candy from my hands that fell and clattered on to the floor noisily.

"You-! Come down here right now, Yasu-chan!" Mom lectured.

I despondently floated down, not daring to look at mom in the face. My mom was fearsome. Of course she would be, she used to be a pro-hero after all. Her quirk gave her the ability to inhale and exhale large volumes of air - allowing her to shoot out pressurized air cannons or even momentarily fly. However, she retired a year or two after I was born. Mostly because she had suffered a debilitating injury on her lungs that severely reduced her quirk's strength, but also partly to focus on raising her child - me.

So she was not unfamiliar with being strict when she had to be even though she is usually a very loving and doting mother.

"You have been really cheeky recently after getting your quirk huh? Do you want me to take away your game box?" She questioned.

Game box was what she used to refer to the game console I had received on my fifth birthday. It was what she usually used to threaten me with when I did something bad.

"S-sorry mom. Please don't!" My face scrunched up like I was going to cry, and my eyes filled up with tears.

"D-don't use that face on me. It only works on your father!" She forced herself to look away, muttering about how I used my 'cuteness' as a weapon.

I continued, however, letting unshed tears well up in my eyes as though they would fall at any moment while blasting the 'puppy dog' face at her at full power.

She saw my face and sighed helplessly, crouching down to my level and squeezing my cheeks, "You're lucky you're so cute. Fine, just clean up the mess and no candy for a week!"

As long as she wasn't taking away my game console, I was fine with that punishment. After all, I could just float up and take the candy when she wasn't watching.

"Yay! Thanks mom, you're the best! I love you!"

She smiled warmly, "Love you too, Yasu-chan. Now clean up the mess."

I bent down and started picking up the candy. But as I did, I accidentally nudged one of them with my feet, causing it to roll under the fridge.

I got on my stomach and tried reaching underneath the fridge to get the candy, but the gap was too tight even for my tiny arms to reach in.

Exasperated, I thought to myself how great it would be if the fridge could float like I could.

The gap suddenly became wider and I could reach in to grab the candy.

"Y-Yasu-chan, are you doing that?"

I heard my mom call out in shock, and as I looked up, I realized that the fridge was now floating in the air.

When my dad got home from work, mom told him about what I had done in the afternoon. Shocked, he agreed that they should bring me to specialists to assess my quirk as well as registering it with government. They told me it was important because since my quirk was different than what they had initially thought it was, they needed to find out just what it could do exactly before I accidentally hurt myself or others with m quirk.

So they brought me to some doctor person who put me through a series of tests over the course of a few days to see what my quirk was.

We discovered that my quirk wasn't floating or flying or anything like that. Rather, it was actually a pretty common quirk. Psychokinesis - a quirk that allowed the user to move matter with their mind. But where a vast majority of the population with this quirk can only pull and push things weighing just a little over a few grams, the scale of my quirk is on a completely different level. Rather than flying, I had been lifting and moving myself in mid air telekinetically.

During the quirk assessment tests, we found out just how much weight I could lift with my quirk. They put several dumbbells that were progressively heavier than the last in front of me, and then asked me to move them with my quirk.

The first dumbbell was just 5kg, which I easily lifted it up with my mind. Since I had already lifted up the fridge which weighed more than a 100kg, this feat did not surprise anyone.

I continued on with the other weights, each one heavier than the last. 10kg, 20kg, 30kg, 40kg and so on. This went on until I reached a dumbbell that I could only barely lift up an inch before I fell to my knees in pain. The dumbbell was 210kg.

This was when we discovered the drawback of my quirk - overuse of my psychokinetic power would result in a massive and terrible headache. Some rest was required for the headache to fade away and for my energy to be restored.

After figuring out the current maximum limit I could move, they wanted to see how many things I could move at once. It was pretty easy to figure out. I could manipulate as many things as I wanted to, so long as the combined total of the weight of the objects did not surpass 200kg. Meaning I could control four dumbbells of 50kg each or 200 objects weight 1kg each.

Next was the speed at which I could move the objects. Once more, it all depended on the weight of the object I was moving. The lighter the object, the faster I could move it. I could move a 200kg dumbbell at only 1m/s, but a 1kg dumbbell could be launched at 200m/s. That was a speed that was a few times faster than a baseball pitch made by professional baseball players.

Finally, I was tasked to levitate myself and others into the air. The doctor had sharply inhaled upon seeing that my quirk was able to exert pressure on other people as well, though I didn't understand what was so special about it.

It was only a basic quirk assessment designed to test the limits of my power, but after the testing was complete, my mother and father told me seriously that my quirk had the potential to be very powerful. They told me I would become a great hero in the future.

I wasn't super sure what they had meant, but hearing that I would become a great hero in the future, I just smiled, nodded and loudly agreed.

But as our little family was celebrating my newly discovered powers, the doctor rained on our parade.

"Shigeo-san, I know you and your wife is very happy about your son's powerful quirk, and I hate to be the wet blanket, but well, Fumiko-san, you were a pro-hero once, so you should be familiar with the problem of children who possess powerful quirks." He sombrely began.

My mom who had previously been exuberant paused before nodding slightly.

The doctor continued, "Your son is able to generate immense force telekinetically, and as we have found out, he can exert this force on both organic and inorganic matter. I'm sure you can see how dangerous this can be without me describing it."

My mom flinched at the thought.

"200kg of force exerted on a human body... it is enough to crush bones. And he has only just awoken his quirk. He is only five years old now, but as he gets older, the limits of his powers will greatly expand. This might sound strange, but if his current limits never change, that would be the best outcome for everyone involved. If it continues growing stronger... Which is why it is imperative little Yasuo must learn to control his powers. As soon as possible. Otherwise, he might become a danger not just to himself but others around him."

My parents looked at each other before turning to me, who didn't really understand all the words the doctor had said, but could sense that the atmosphere had changed very suddenly.

My dad nodded, "We understand doctor. What should we do?"

"It is good that he only recently awakened his quirk. He still has a year before he starts attending Elementary school. I recommend letting him stay here until that time, so that he can learn how to control his quirk safely."

Mom furiously shook her head, "Impossible! I won't let Yasu-chan stay here for an entire year! He needs to be with us, with his parents!"

"I understand your concern madam, but if it is between letting your son stay here or having the possibility of him hurting himself with his own quirk one day, which one would you prefer?"

"That is-! Why are these the only two options!"

I looked between the doctor and my parents, unsure of what it is they were arguing over. I pulled on my mom's sleeve, "Please don't make me go away, mom. I don't want to leave you and dad."

My mom immediately crumbled, pulling me into her embrace, "There is no way. I won't let you take Yasu-chan!"

"Fumiko..." Dad started but was silenced with a furious glare from mom.

"Please don't misunderstand, madam. We won't take your son forcibly, we're not monsters. It is entirely up to you, his parents. However, I beseech you to please reconsider. Right now we can't force you to do anything, but the day your son accidentally hurts someone with his quirk, we will have to take him away for the safety of both him and everyone else around him. With or without your consent." The doctor ominously explained.

"If anyone tries, I will-!" Mom's face scrunched up in a cold fury as she began seething with rage.

"Fumiko!" My dad, who is usually very passive and accommodating to his wife sternly called out.

Mom flinched, before sharing a look with dad and then deflating helplessly in concession.

The doctor continued, "Perhaps we can come to a compromise? Instead of having young Yasuo stay here full time, you can bring him here every morning for him to learn control, and bring him home in the evening? That way Yasuocan be with his family while minimizing the risks of injuring himself?"

Mom and Dad looked at each other briefly and both nodded at the same time.

"I... I can accept that compromise. As long as Yasu-chan won't be taken away from us, that is fine." She said.

And that was how I started learning to control my quirk from specialists.

-(Time skip 6 months - Yasuo age 5)-

It has been a few months since I started going to the Quirk Assessment Center to learn how to control my quirk.

Because I had to go to the QAC almost every day of the week, barring Saturday and Sunday, from morning to evening, I had to stop going to preschool. Which really sucked cause I liked going to school and having fun with my friends.

I was stubborn at first, insisting that I would never hurt anyone with my quirk, accidentally or not. But when he asked how I would feel if I accidentally hurt mom with my quirk by not learning how to control it, I had to admit that it would be a sucky feeling.

The bright side was that I got to play with my quirk everyday as well. The doctor told me that I needed to learn how to control my quirk so that I won't accidentally hurt anyone.

Initially, rather than pushing the limit of my quirk by asking me to lift heavier and heavier things, I was told to do simple, mundane, everyday tasks with my quirk rather than my body. Eating, writing, tying shoelaces or even playing with LEGO blocks. Tasks that needed fine motor control even when using your own hands.

After that was done, the doctor wanted me to be able to perform intricate actions with my quirk like painting and drawing or completing what he called dexterity puzzles.

A few of those puzzles were really fun, like having to telekinetically move around a box that had a clear lid in order to manoeuvre the tiny metal ball inside a maze to fall into a hole. Or playing an old school board game called Operation, where I had to carefully use a small tweezer to remove plastic ailments from small cavities. If the tweezer touched the edges of the cavities, the 'patient's' nose would turn red and an alarm would buzz.

At first it was difficult, like I would accidentally crush the maze box, shattering it into pieces when I got frustrated or excited. Or when the tweezers would violently pierce through the board game when I recoiled from the loud alarm. But after some time, I became more capable at using my quirk. Not in terms of strength and speed, but in terms of control.

Here I learned that often times, there were some problems that could not be solved with brute force. Sometimes, a gentle hand can be more effective at solving a problem than a forceful one.

After awhile, I could move things with my mind even better than I could with my own hands. Painting while holding a brush with my psychokinesis could produce a work that would better resemble the picture I have in my mind as compared to painting with my own hand.

Dexterity puzzle games could be completed in just a few seconds, or even shorter if I cheated and controlled the tiny metal ball in the maze to move through the labyrinth by itself.

I was then taught how to play the ukulele, a tiny guitar. The doctor wanted me to only use my quirk to play the ukulele, which was easier than I thought after going through all the previous exercises. I learned how to play all the chords in just a day and then moved on to playing scales, a set of musical notes in ascending or descending pitch, and then subsequently chords.

Here I learned how to form what I can only describe as invisible hands. They were like intangible, astral constructs that helped me with more delicate tasks such as playing an instrument. When I explained to the doctors what I did, they asked me why I described them as hands. I answered honestly that I didn't know. They guessed that maybe it was because I was most familiar with hand-like appendages, but theorized that it was possible for there to be no restrictions in the shape of the constructs I could create.

It wasn't long before I became proficient in the instrument, being able to play an entire tab with just my psychokinesis. The first song I was taught was an old song called La Vie En Rose. Of course, if I tried it with my hands it would sound like complete rubbish.

Manipulating objects with my quirk was completely different to touching them with my own physical hands. My quirk was directly connected to my mind, I only had to will it in order for my telekinesis to move instantly as I wanted. My hands, on the other hand, required fine motor control that needed to be trained in order to achieve the level of dexterity I had with my Psychokinesis.

I enjoyed learning to play instruments, and the specialists at the Quirk Assessment Center was only too willing to oblige my requests. I moved from the ukulele to the guitar, the violin and then the piano.

The violin was the hardest to pick up, because unlike the guitar and ukulele where I could just strum the strings with my 'Phantom Hands', dubbed by the doctor, I had to manipulate the violin bow in concurrence as well. The piano was my fondest instrument. Simply because unlike most pianist, I was not confined to having just two hands to play the piano.

The most complicated and intricate sonatas could be performed by me with ease as long as I knew the chords.

After the past few months of learning control, the doctor decided that my education in control was complete. He was now confident that it would be unlikely for me to hurt anyone accidentally with my quirk. After all, he claimed, if I could play Beethoven's Sonata No.29 on a piano while at the same time play Concerto in D Minor by Sibelius on the violin, chances are it would take conscious effort on my part to, for instance, break someone's bone.

Now that he was confident in my control, he wanted to see if my maximum capacity of, for lack of a better word, psychic energy could be increased with training. So I was set to the task of pushing my limits every day, lifting heavier and heavier objects, and moving them faster and faster as well.

In the blink of an eye, it was finally the last day of my training in the Quirk Assessment Center. While, to be more accurate, the last month of my training was not at the Quirk Assessment center. When I reached the maximum measurement capacity of the laboratory, I had to go to a specialized facility to continue training the maximum output of my quirk.

On the last day of my training, the maximum force I could generate on a single object was measured to be 2,680 kilograms. And the speed at which I could move a 100kg metal weight was measured to be 166 metres per second - slightly less than half the speed of sound. But the force of the 100kg weight impacting the measuring device at that speed was roughly equivalent to 16,600 newtons or 16.6 kilonewtons. That was more than ten times the force of a medieval cannonball being fired at the muzzle.

Or at least that was what I heard from the Quirk Specialist. I didn't understand a word of what they were saying, but the way they were saying it made me feel proud.

The reason why my quirk training was ending because next week I was starting Elementary school, where I was repeatedly and vigorously told that I could not use my quirk. Quirk usage in public places were considered illegal, with the only exception being pro-heroes or other civil servants like policemen and fire fighters. With the concept of control being hammered into my brain for the last year, it was not a difficult rule to follow.

Yet, at the same time, I had been constantly using my quirk for almost every aspect of my life for the past year. It might be difficult to reconcile the two contradictory concepts while I got used to not using my quirk in school. I wonder why do adults always send mixed messages?

Disclaimers:
1) No system, no reincarnation, no transmigration and absolutely no harem.
2) OC is still a kid. Even when the main story picks up, he is still a teenager. He is not perfect, nor should he be expected to be even if he tries very hard to be perfect. A lot of things from his perspective is seen through the lens of a teenager.

FAQ:

Why does Yasuo need to go get taught how to control his quirk when someone like Bakugo doesn't?
Bakugo's quirk, though explosive in nature, does not have the potential to kill and maim with ease like Yasuo's does. Bakugo at 5 years old could generate fire-crackers in his palms. Yasuo can twist off someone's head with a thought at 5.
