Dr. Garaki, one of the oldest living people in the world, a man that is only fair to call him one of the greatest minds the world had ever seen, and the greatest quirk researcher to ever exist. He rarely found himself unable to comprehend something or come up with a theory to explain.
And Junsei's behavior was one of these things he couldn't understand. The old doctor still didn't know how Junsei had slaughtered nomus and why he was still alive. Junsei was a ruthless killer with a complete disregard for life, while he was the servant and friend of his enemy, AFO, and the one responsible for creating nomus and many more atrocities.
Yet, he had spared him. It made no sense.
Junsei's behavior was inconsistent and illogical no matter which angle one viewed it. He had killed innocent people, so why spare him? No matter how much the doctor thought about this, he couldn't come up with a single answer.
In the end, he chose not to continue questioning his survival too deeply. He was alive and he had more important things to worry about.
The old doctor had lived long enough to recognize when a situation had turned hopeless. Junsei's appearance in his secret lab had made one thing abundantly clear. Japan was no longer a place where someone like him could operate freely.
At the same time, the encounter had only strengthened his resolve. His ambition had grown. Garaki swore to himself that he would create something that surpassed any other being in the world.
A being greater than AFO. Greater than Junsei. A perfect existence. And once that existence was complete… he would avenge his master and honor his dream.
His thoughts naturally turned toward one individual.
Shigaraki.
The brat was crude, unstable, and irritating in many ways. But there was no denying his potential. More importantly, he possessed the correct mindset, the hatred, the emptiness, the obsession with destruction.
He had a chance to become something greater. To become the body AFO dreamed to possess.
But unfortunately, the boy proved to be as stupid as he was promising.
"I'm staying in Japan," Shigaraki had said.
Garaki still remembered the irritation that flared within him at those words.
The brat wanted to continue his teacher's legacy. He spoke of ruling the underworld, of rebuilding power from the shadows with his small group of misfits.
It was laughable.
Garaki's expression had darkened at the time.
[Who does that brat think he is?] he had thought.
Shigaraki was still an insect compared to the true forces of the world. Even regular top heroes could crush him if they truly tried, let alone the true monsters among heroes.
And now…
Junsei existed.
A monster that proved to be superior to AFO and All Might.
Still, Garaki had spent several days attempting to convince Shigaraki. He attempted to reason with him, he gave warnings and even offered incentives.
But Shigaraki refused to listen.
The others followed his lead.
Fools.
After wasting enough time, Garaki reached a conclusion. Their potential was not worth the effort. He can find someone else.
With his mind made, he decided to leave Japan alone.
Garaki contacted his overseas connections and began activating old contingency plans. Among them was a backup facility located in Korea, one prepared long ago by AFO in case of emergency evacuation.
A precaution that now proved invaluable.
However, the process of relocation was not simple. Garaki's resources and equipment were scattered across multiple hidden facilities, warehouses, and underground labs throughout Japan. Without All For One's network and influence, consolidating everything became a slow and painstaking task.
Weeks passed.
Piece by piece, equipment was moved. Garaki could not afford to abandon anything. Every resource mattered now that the source was gone.
Yet during that period of waiting, something unexpected happened.
Shigaraki and his group attempted to establish a connection with the Yakuza, some kind of a fake alliance for a hidden goal, though the details were unclear.
But then Junsei appeared at the Yakuza's base. The entire plan collapsed instantly.
Shigaraki's group fled the moment they saw Junsei. They didn't question his presence. They didn't wait to see what had happened to the Yakuza.
They ran immediately.
Garaki found himself nodding in approval when he heard that. For once, they made the intelligent decision.
But the incident had a deeper impact. It shattered whatever illusion Shigaraki's group had been clinging to. Junsei was actively moving and killing thugs and criminals everywhere. They knew it wouldn't be long before they ran into that monster and became another victim of his.
Naturally, Garaki seized the opportunity. He approached them again with his promise of power. He insisted that only through his work can they surpass their limits and reach the heights of AFO and Junsei, even surpassing them.
His words were met by hesitation. But in the end, their desire to power made them agree to follow him. They wanted to grow stronger and then return to Japan to finish what they set out to do in the first place.
But Junsei's shadow did not fade just because they had crossed the sea. Only weeks after settling into their new underground base in Korea, the news reached them, Tartarus had fallen at the hands of Junsei. Every prisoner had been slaughtered.
At that news, all of them had the same thought. Leaving Japan was the right call. Because if Junsei had found them, they would have just become victims to the monster, just as easily as those inside Tartarus.
That realization stayed with them, quietly poisoning any thought of returning to Japan unprepared.
And from there, it only grew worse.
Not long after, strange disturbances began surfacing across Korea. At first, they were minor, an unusual number of insects, pests appearing in the base more frequently than expected. Then it escalated into something far more disturbing. Cockroaches swarmed in coordinated clusters. Spiders attacked in the middle of night and appeared in unexpected places. Rats chewed through supplies and wiring with a persistence that felt intentional.
The underground base, designed to be hidden and secure, was being harassed constantly. Day and night.
At first, they wondered if something was attracting them and causing this ridiculous situation.
Two days into this unnatural harassment, the next wave of news arrived and it changed everything. Junsei had declared war on humanity.
Literally.
Reports spoke of Japan's top heroes being wiped out, followed by a systematic slaughter of civilians. People dying by the millions. Humans turned into zombies. Animals moving with the sole purpose of killing humans.
Only then their situation made sense, whatever Junsei was doing, he was affecting the entire world. And that scared them, the monster possessed power to affect the entire world and even declared war on humanity.
But what truly horrified them the most was Junsei's methodical genocide. They were villains. Some of them wanted to destroy society, to tear down the world and rebuild it how they thought was right. But not one of them had ever imagined going this far.
This was extinction. A genocide for the sake of genocide.
And in that moment, Junsei stopped being human in their eyes, to the villains, he was the true definition of a bloody monster.
A week after the war declaration, the world responded with everything it had. The strongest heroes gathered, forming an army meant to bring down the monster. The League followed the battle just like the rest of the world, watching as Junsei faced them all without hesitation.
Then came the nuclear strike.
For a brief moment, it looked like humanity had succeeded.
But when Junsei survived, when he rose again in a form that was no longer human, something in their understanding broke. The word 'monster' no longer fits Junsei. It felt too small, too simple for what he truly is.
They understood that they had been wrong from the start.
What they were dealing with was far beyond that.
Fragments of what followed reached them slowly. The destruction of an entire city in the United States in the span of minutes. The complete helplessness of military forces. The sheer scale of power that no longer resembled anything within human limits.
But just as suddenly as it began, it stopped.
There were rumors. An agreement. That the demon had chosen to halt the genocide under a condition, humans were to stay away from nature entirely. Forests, oceans, mountains… all of it forbidden.
The story sounded absurd.
But none of them questioned it.
Because they had already seen enough to know one thing for certain.
They needed power. They needed to transcend human limits.
That was when the real experiments began.
Shigaraki volunteered first, driven by the desire to surpass everything, including Junsei. Dabi followed out of a more personal rage. Junsei had taken from him the chance to settle his own score with Endeavor. Spinner joined them to stand beside Shigaraki and help reshape the world.
The procedures were brutal.
Garaki threw all caution and pushed them as hard as he could.
He was not looking for enhancements anymore. He wanted fundamental transformations. Their bodies were pushed beyond human limits, broken down and rebuilt again and again. And Junsei became the standard to aim for.
But not everyone agreed to this madness. Some members of the League refused outright. They chose instead to train their quirks, to grow stronger through their own means rather than submit themselves to Garaki's methods.
Time passed.
More than a year of continuous work, refinement, and failure.
Until finally, Garaki succeeded.
He found a method to elevate the trio to a level of power that surpassed anything he had worked on before. A method that might give them the power to stand up against the faceless demon.
Standing within the depths of their hidden base, Garaki looked at the three before him and allowed himself a small, satisfied smile.
The time for hiding was over.
The League of Villains was ready to return to Japan to dominate just as AFO had wanted and Junsei would die.
