Chapter 2:

"Please help me Jishin, it's so boring having to kill all the criminals in one hit." Saitama whined as he rolled over the floor

"Well that's your fault for training that much! Who in their right mind would do that for literally 3 years!" Jishin retaliated as he laid face up.

" Please help me, It's not like I wanted to become this str-"

"You know damn well that you trained yourself this hard everyday just to become this superhero! and NOW you're just complaining that everything is too easy!" as he pointed and glared at Saitama.

"Well… you know… we can just spar each other…. How long has it been since we have done that…"

"No"

"C'mon why?"

"Last time we did that, you almost leveled of the entirety of the cities, and if I wasn't there who knows what would have happened to those cities."

"Well you got stronger haven't you? You can withstand the full strength of my blows" Saitama countered as he slapped his bicep.

"I could say the same to you too, except for the fact that, this was 8 months ago. And before you spout out any more stupid ideas, I doubt I can withstand any of your blows."

"But-"

Before Saitama could finish his sentence or for Jishin to get mad at him, both of them turned their attention towards the TV screen that was blaring the news channel. The news reporters along with the people in the surrounding area where in panic as a being that was unbelievably tall wrecking City A.

"In City D, we have confirmed that there is an individual who is destroying parts of the town, we have also gathered that this is a Demonic level threat and it is headed to City B. All civilians evacuate to a safe area."

As soon as the reporter had finished, both Saitama and Jishin glanced at each other before slowly getting up from their positions and heading out of the door.

15 Minutes Earlier in City D

2 Men in an unknown location:

"At last I have completed the Ultimate Steroid-Biceps King!" Fukegao the scientist stated

"Big Bro…"

"Marugori! Drink this for the strength that you desire!"

As Marugori drank the entirety of the serum that was inside of the test tube, he grew rapidly to a humanoid that towered the entirety of humanity. He broke through the ceiling and later crushing the entirety of the lab they were originally in.

"With our powers we will be able to rule over the world, but before you go, help me I am trapped under this pile of rubble."
The massive, once human, humanoid grabbed his brother and placed him on his shoulder.

"Yes this is perfect, I'm the Brains and you're the Brawn! We're combining the greatest minds and the strongest body! We Brothers will conquer Earth and rule as kings!"

As they stormed through the city D destroying everyone in their path, they didn't notice the other two humans that were near them. It wasn't until Fukegao turned his head to the other side of his brothers shoulder.

"WHAT?! SOMEONE'S RIDING YOU!" he shrieked

He stared at two humans one who was casually sitting down on his brother's shoulder and relaxing as if not caring for the slightest, while the other had a blank face staring upwards.

"Put on some undies." Saitama boring replied

"YOUR SHOULDER! KILL THE GUY ON YOUR SHOULDER!"

The giant moved his hand and swatted the human on his right shoulder. As he moved his hand away from his shoulder slowly towards his face, he realized the big mistake he had done. It was his mutilated brother that was now in his hand. With that realization, the giant was sent into a fit of rage like none other.

"HOW DID THIS HAPPEN?! I JUST WANTED TO BE STRONG… AND I FINALLY BECAME THE STRONGEST MAN!"

Saitama being Saitama, doesn't understand the situation as he mocks the villain with a massive grin.

"So how does it feel?"

Knowing what was about to happen, Jishin slowly got up and started to fly up into the air, knowing already what was about to unfold. The giant grabbed Saitama from his shoulder.

"I don't know who you are but it's your fault that my brother had died! Now you're gonna pay for it!"

He slammed Saitama to the ground. Before Saitama to stand up the giant once again stomped on the spot where he lay.

"BEHOLD THE POWER OF THE STRONGEST BROTHERS!"

The giant stood there motionless thinking to himself, that he got revenge on the person that killed his brother. But after realizing what he had done, he didn't feel anything, he felt…. nothing. Out of nowhere Saitama breaks through the newly created crater and punches the giant's face. His face concaves inward until it is complete mush. The giant slowly falls backward and is headed straight toward city B. Before it could impact the city, Jishin stops the falling corpse and levitates it.

"Saitama…. Why do I always have to be the one to clean up your mess?"

"Well you never really fight the monsters sooo…."

"At least think about the repercussions, just… Nevermind."
