Yo guys, I've been wanting to write fanfiction for a while now, but most things I've watched/read I've either forgotten, not been interested in doing a fanfiction of, or haven't read the manga of. It feels wrong writing fanfiction of something with a manga you haven't finished. Anyway, none of those apply to OPM so I decided to try it out. I've made it rather easy on myself here since OPM is fairly easy to write fanfiction of. With a main character that literally only needs one punch to end all fights all I really have to worry about is spicing up the plot, adding some character drama, and trying to express the hype of OPM fights on a page. Should be pretty relaxing to write. Which is nice since, you know, I have basically zero experience writing anything longer than two thousand words. Anyway, onto the story.

Prologue

"God, we have run into a problem." A black cloaked figure said as he appeared in front of a glowing white mass.

"What is it?" The glowing white mass—who was apparently god—asked.

"You know that indestructible, immovable limiter you placed on every single living being—us included—to prevent anyone being from growing too powerful?"

"Yes, I do in fact remember. I do somewhat regret putting one on myself, but I suppose that's just a testament to how wise that choice was. I would undoubtedly be corrupt without it, and I can't imagine what other, less-wise beings would do with such power."

"Yea, about that... Some random wannabe hero managed to remove his..." Awkward silence permeated throughout the empty white void.

"What?" God's voice came out with a mix of embarrassment and pure, utter confusion. "How? Even I haven't managed to break it. What kind of insane stunt did they pull to manage that?"

"Um... well..." The cloaked being seemed reluctant to share, not wanting to embarrass the god any further. "He... did it through training. Lots of training. Like, the guy is actually really stupid. He had absolutely no idea that there was such thing as training too much, so he just kept training. As you know, once your body is injured enough that it should by all rights be dead, then you can, theoretically, experience a major increase in strength if you have the willpower to keep yourself alive in said state. This is because of your soul strengthening, and it, in turn, strengthening your body. Now, this idiot somehow kept himself in this state—by training—for two and a half years straight. The rampant and constant increases in power were at war with your limiter for about a year, and your limiter eventually lost." The sheer ridiculousness of the situation managed to throw off even god himself before he eventually regained his bearings and replied smartly and elegantly.

"What the hell?" Ok, maybe not.

"I don't know either sir."

"So, let me get this straight. Right now, at this very moment, we have some stupid human mortal walking around with a soul so ridiculously powerful that him passing on would likely end the entire multiverse?"

"Well, not exactly."

"What do you mean 'not exactly?' Is there more?"

"Upon breaking the limiter, the soul became so powerful it overwhelmed the host's mind, leaving him an emotionless, thoughtless husk."

"Really! That's great news! All we need to do now is overlay the mind of a trustworthy individual over the body! And since there is currently no mind, the soul won't have any basis for mental defenses, meaning it'll be incredibly easy to input the mind too!"

"Yeah, about that... You know Rob?" If a mass of glowing white energy could sweat, it would.

"Oh. Oh no. What the hell did he do!?" God screamed.

"He decided to act without referring to anybody and took the mind of a random, ordinary guy and threw it into the body." Silence once again filled the void, though this time, they wished it was the awkward kind.

"Make arrangements to erase Rob from existence. No funeral will be necessary, he won't be missed."

Disappointment is something Alan is familiar with. He, like any other red-blooded high school boy, greatly desired to be a hero. Working for the Hero Association was any boy's greatest dream. They were paragons of justice, looked up to by just about everyone. A regular topic of discussion at his school was about which S-Rank was the coolest. While those talks could get quite heated, everyone still managed to agree that they are all awesome. Even the more morally questionable ones are still pretty damn awesome.

Guided by the desire to achieve the same awesomeness, Alan decided to try his hand at the exam. He'd trained since middle-school, working out regularly to build his muscles to an acceptable place. Yet, even with all his training, he was woefully unprepared for the examination.

Heroes are people who are unreasonably strong. They are meant to protect the common-folk from deadly threats that could result in many casualties, so expecting them to accept somebody who probably can't even take on a single, average adult human is unreasonable. Nonetheless, he still tried. And failed. Horribly. Like, really badly.

So badly in fact, that even nearly a month later he was still feeling the effects. Well, mostly. The results of the examination itself wasn't a big deal, the big deal was the people who relentlessly made fun of him for thinking he could actually make it in. His parents laughed at him for a bit when he failed, probably because they long since predicted the end result, and while that definitely hurt, his classmates were the real issue.

He'd always been a bit awkward. He had a cheerful exuberance about him that drew quite a bit of unintentional attention, and then, the moment he got said attention, his exuberance switched to a timid nervousness. It wasn't the worst, and he was a fairly endearing person, but upon starting his heroic training in middle school he'd been hyping up his future as a hero for years. People made fun of him about it then too, but between his passion and the few people that did actually believe in him, it was easy to ignore.

And then he failed, and everything went downhill from there. He became the laughing stock of the entire school. The few friends he'd managed to maintain had been forced into the position of semi-close acquaintances, most embarrassed to be around him but still having enough loyalty to not blow him off completely. It sucked, and with no one to really support him and his parents not caring, it really had an effect on the young teen. So much so that he'd even abandoned his training because he felt silly whenever he tried starting again.

Staring up at the moonlit, star-filled sky, Alan's naturally optimistic mind tried its best to hold back his feelings of inadequacy. He couldn't help but question how well his desired job really fit him. If he couldn't even endure some petty bullying, how would he endure the daily death matches heroes were said to have. He'd fail, just like he did on that test.

His thoughts were interrupted by a flicker of black in his peripherals. Looking down, Alan spotted a black-cloaked, six-feet tall humanoid creature with distinctly skeletal hands. Alan stared at the thing uncomprehendingly for a few seconds, before-

"MONSTER!" The scream pierced through the air, filling the empty streets and likely waking up more than a few people.

All of Alan's previously self-loathing thoughts were abandoned as his instincts took over. He vaulted off the bench and began sprinting away full-speed, not entertaining the thought of fighting for a second. The black-cloaked monster simply stood there, watching him curiously, before making its move.

Alan stood no chance. The monster appeared in front of him in the blink of an eye, and Alan nearly ran directly into it. In a panic, he stumbled and fell onto his butt. His chances of escaping were now zero. Between the monsters speed and Alan's current position, only a hero could save him now. Alan, mind already beginning to fall into a depression before even encountering the monster, didn't have any hope.

This encounter only served to prove Alan's helplessness. All those years of resolutely training to become a hero didn't prepare him for a real monster. His illusions of bravely facing down Dragon-level monsters were all just that, illusions. Stupid, arrogant illusions. If he actually succeeded in passing that exam, he would die.

With his dreams, hope, and confidence shattered, Alan gazed up at the black-cloaked figure with acceptance. He no longer had any purpose, the monster was only doing him a favor.

"You're welcome for this, boy." It seems the monster realized this too.
