Welcome to the One-Punch World

"Hahaha..."

"Crush them all for me!"

"We brothers are the strongest!"

The originally peaceful city was shattered by the appearance of a powerful figure!

A naked giant was rampaging, and on the shoulders of this bird-flashing giant, a scientist with a crazed expression was laughing maniacally.

"Run!"

"It's a Monster..."

"Damn it, why is this Monster so big?! Where can we run in this situation?"

Countless residents in the city shouted in terror as they looked at the terrifying giant standing on the earth.

"Mom..."

"My child!!"

"Run! There's no time to wait..."

"We absolutely cannot stop!"

On the other side, in the street, accompanied by wails, a white figure appeared out of thin air amidst the panicked fleeing crowd...

"Host has arrived in the world of One-Punch Man..."

"Initiating world mission..."

"World Mission: Defeat ten Dragon-level Monsters..."

"Forget it, Master, you can just handle it yourself!"

"As long as you collect enough energy and gain a certain status in the world, allowing the system to establish sufficient connection with the world, the system can gain partial rule-making authority over this world."

Jupiter's artificially unintelligent system, "System-chan," began to explain its abilities to Jupiter. It seemed "System-chan" already knew that no matter what mission she assigned, her creator would absolutely refuse to do it, so she simply gave up and told him to do whatever he wanted...

"Eh?!"

Jupiter stared wide-eyed at the system in his mind.

"This system is actually being honest. You're so obedient, it makes me a little uncomfortable."

Artificial Intelligence System-chan: "..."

"So this is the world of One-Punch Man?!"

Jupiter looked at the countless screaming people around him, contemplating his location. Only by understanding the city he was in could he decide on his action plan in the world of One-Punch Man...

"Run!"

"Save me!"

"Ah!!!"

"Damn it, it's too noisy..."

Due to his greatly enhanced senses, the constant screams from the people around him were buzzing in Jupiter's ears, making it impossible for him to calm down and determine his location.

"Um..."

Finally, Jupiter stopped a lucky passerby.

"Excuse me, do you know which city this is?!"

Jupiter asked, looking at the bald uncle he had stopped.

"Ah! Ah!!!"

The bald uncle kept screaming as he looked at Jupiter.

"Ah?!"

Jupiter was stunned by the uncle's shouts.

"Boom!"

The next second, with a muffled thud, Jupiter and everything around him were crushed under a giant foot.

"Brother! I'm invincible now..."

The tall giant shouted loudly.

"Yes! Little brother! With your body and my brain, we are invincible..."

The mad scientist shouted loudly.

"Boom!"

At the moment the giant and the mad scientist were conversing, a violent force erupted directly from the sole of the giant's foot, launching the giant into the sky!

"Huh?!"

The giant brother flew into the air, his eyes wide open. 6̾9̾s̾h̾u̾x̾.̾c̾o̾m̾

"Brother! Did you see? I awakened the superpower of Flight!"

The giant younger brother said dazedly, completely intoxicated by his own power.

"Idiot brother, how can humans fly? The potion I invented for you doesn't contain any superpowers related to flying!"

The crazy scientist older brother hugged the giant younger brother's shoulders and shouted loudly.

"Then brother, how did we fly?"

The giant younger brother felt incredibly strange, he couldn't understand how he was able to fly.

"We must have been thrown into the sky by something!"

The crazy scientist older brother deduced with his impressive IQ of 250.

"Thrown into the sky by something? How is that possible?! I am already the strongest being in this world, how could anyone throw me into the sky?!"

The giant younger brother couldn't comprehend it at all. He was the strongest being in this world, and no one could possibly throw him into the sky.

"You damn brat! How dare you be so disrespectful?! Do you know who I am? Do you have the strength to provoke me?"

Just as the giant younger brother was flying in the air, a white figure instantly appeared beneath him.

"You are..."

The giant younger brother's eyes widened as he looked at the white figure.

"I don't care if you want to become the strongest in the world, or if you want to conquer the world... that has nothing to do with me..."

"But, you dared to step on me, so this has become my business. Since you don't know where you can and cannot step in this world, let me teach you a lesson."

The white figure's face turned ashen, and his eyes blazed with fiery intensity.

In an instant, he severed the giant younger brother's legs. Endless crimson blood poured out from his severed legs, transforming into massive, scarlet raindrops that smashed into the ground of D City, creating countless craters.

This wasn't the end...

As the giant younger brother's legs hit the ground, they instantly triggered an eight-magnitude earthquake. The terrifying Shockwave completely destroyed several city blocks...

"Ah..."

The giant younger brother cried out in pain. He was in immense agony, but because he was currently flying in the air, he was powerless to retaliate.

"Go to space and keep Kaz company, little giant brother!"

The white figure seemed to have no intention of killing the giant directly. He put force into his hands and propelled the giant younger brother's torso towards the endless sky.

The giant younger brother's torso pierced through the clouds and continued upwards, eventually breaking through the atmosphere! He flew into space!

"Motherf*cker!"

The white figure watched the giant younger brother, who had become a satellite, and extended his right hand towards the sky, giving the international gesture of friendship.

In the vacuum of space, a tall giant, having lost his legs, orbited the Earth. He gazed at the beautiful, fiery sun outside the planet and then at the incredibly beautiful blue planet before him...

"What a beautiful planet..."

"Brother, this way we can be together forever, accompanied by this beautiful scenery!"

The giant smiled with relief as he looked at his brother, who had been freeze-dried using the most advanced technology and was now beside him. He thought to himself that nothing was as happy as being with his good geigei, and in the end, the happy giant younger brother gave up thinking.

"Hoo..."

Above D City, Jupiter's eye twitched slightly. Anyone who was stepped on forcefully less than five minutes after arriving in a new world would probably be angry...

Jupiter looked down at the D City, which was riddled with holes from the destruction. The anger in his heart gradually subsided.

"I did a pretty good job..."

Jupiter looked at the city, which was now only half-intact due to the giant's falling legs, and smiled brightly. Without a doubt, Jupiter had done his best to protect the city's inhabitants from the threat of the evil giant. He was a great hero!

"I need to gain a certain status in this world so that my mentally challenged system can establish a strong enough connection with this world. This means the higher the status, the better. Simply put, I need to become everyone's Ancestor Person."

Jupiter's analysis was sound and logical. In simple terms, there was no mission that couldn't be accomplished by Jupiter becoming an Ancestor Person. If there were, he wouldn't do it...

If there truly was a mission that couldn't be accomplished by Jupiter becoming an Ancestor Person, it definitely wouldn't be Jupiter's fault; it would be the mission's fault, and the mission would need to be revised!

"This world has two organizations: the Monster Association and the Hero Association. This means that as long as I choose one of these organizations and become a cadre within it, the system can establish a strong enough connection with this world, allowing the system to gain partial control over this world's rules. Then, I can just quietly wait for that scammer Boros to arrive..."

"So, should I join the Monster Association or the Hero Association?"

Jupiter pondered.

"I only have one choice..."

A few seconds later, Jupiter made his decision. This wasn't a question that required much thought.

"Only children make choices. An Ancestor Person's answer is all of them."

"Dual Chairman (Ancestor) of the Monster Association and the Hero Association. That sounds good..."

"So first, I'll head to the Hero Association to get an S-Class Hero certificate."

After finishing his thoughts, Jupiter flew directly towards the Hero Association.

"Those here to take the test, this way..."

"We have 'professional' judges to score everyone."

In the vast gymnasium serving as the testing grounds, staff members guided the hopefuls preparing to become Superheroes as they participated in the tests.

Just as countless individuals who believed they possessed the qualifications to become heroes began their assessments!

"Boom!"

Accompanied by a roaring sound, the massive gymnasium's roof was directly blasted open.

A man clad in a white, form-fitting suit floated quietly in the air, his red cape gently billowing with the airflow behind him.

"This is the Hero Association's assessment site, correct?"

The man, standing in mid-air, inquired of the dumbfounded crowd of test-takers.

The heavens resounded with a great noise, and the ancestor made a dazzling entrance!
