The young man that now habitated Saitama's body had realised something important after a few days inside this new body. He had the strengh, the speed, the reflexes and the endurance but he lacked something......Experience. This new body was used to fighting, it had done nothing but that for three years. However the young man's mind was anything but prepared to face mysterious beings.

That and he actually lacked basic knowledge of this world. Because contrarily to what he thought, it was different from the original one. Many things were different, but the thing that shocked him the most was the fact that the supercontinent where all Humans lived was a lot bigger than he thought. It may had seemed small because the cities seemed small, but it wasn't the fact at all. A-City was bigger than any city that had existed in his old world, and K-City was filled had some of the biggest parks and forest he had ever seen.

In only a few weeks he had learned so much, and it was a good thing for him. He was so lost in all those discoveries and his thirst for knowledge that he completely forgot to send an E-mail to Agoni. When he finally remembered it, he decided that it was best to first get some fighting experience before becoming a pro Hero.

He didn't know much about the future ennemies in the webcomic, but he was quite weary of Garou and Blast. One had an unlimited potential and the other was potentially the strongest Hero in the world. Even though the young man still doubted that anyone was stronger than Saitama, there still was a chance that something could be a threat to him.

He wasn't as brave as Saitama, he also had no desire to save people, but he had to play the role. He was nothing but a Fake Hero, but he was still powerful enough to live the life he wanted.

( A few weeks later, Undergrounds tunnel under Z-City)

He was quite shocked to find that there was a lot of underground tunnels under Z-City. He first thought that it was the doing of the Monster Association, but was quite surprised when he was attacked by unknown creatures just after he entered one of these tunnels. They looked like monkeys, but had muscular human bodies and long black hair all around their head, making it look like they had a collar of hair. They also wore golden bracelets around their wrists for some reasons.

They weren't fast or strong but they were quite good at scaring the crap out of him. Since he was in a tunnel he thought they would only come from behind or from the front, but those bloody monsters somehow found the way to attack him from the sides, getting out of the dirt walls. They seemed to really like attacking in an instant, because everytime they attacked, they got out of the walls as fast as they could, tried to claw at Saitama and jump in the holes in the walls to escape. Which is why our dear Saitama now has a few veins on his bald head ready to pop while his face was all red with restricted rage.

This tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.

He wanted to destroy the whole tunnel but decided against it. He needed to know what was at the other side. So he just continued to walk, dodging the monsters that still attacked him as if they didn't see how uneffective it was. Though it was actually a good training for him.

After an hour, Saitama arrived in a gigantic cavern filled with those monsters. They were sleeping on the ceiling cavern, they seem to use the claws they had on their feet to hang on the ceiling. Saitama, seeing how many of them were there, decided to walk on tippy toes so as to not wake them up.

He somewhat reached the middle of the cavern and gazed at what seemed to be a red crystal levitating over a group of those monsters that looked like they were praying. He tried to approach it but the crystal suddenly glowed, which made Saitama stop. The monsters that were praying didn't pay any attention to him and the others still looked asleep, so Saitama decided to go for it.

He prepared himself and jumped towards the crystal. In a burst of speed he reached the crystal, grabbed it and landed on the wall before launching himself at the entrance of the cavern. And just when he reached the entrance, he heard it.

*ROAR!!!!*

"FUCK!FUCK!FUCK!!" Saitama cursed repeteadly as all the monsters in the cavern woke up and rushed towards him. He started to run as fast as he could, which meant that he was a few seconds away from reaching the surface, since he was easily one of the fastest men alive. Yet the creatures seemed to be fueled by the rage they felt over the fact that Saitama stole the crystal, their eyes were glowing a bloody red and they were moving much faster than before. They still couldn't keep up with him, so one of them had an incredible idea.

Saitama looked behind him in time to see an incoming black blur. He barely dodged it but had no time to sigh in relief as another came towards him. This time he decided to simply punch whatever was coming towards him, and saw that it was one of the monsters. He looked at the others that were still pursuing him and his eyes widened.

"YOU MOTHERFUCKER!! WHY THE HELL ARE YOU THROWING THEM AT ME?!!" Yelled Saitama enraged that one of those monsters was throwing his little friends at Saitama.

"ARGHHH!! FUCK IT!!! I AM SAITAMA BITCH!!!!"Yelled Saitama, suddenly stopping and turning around which made the monsters freeze in fright.

Saitama rushed at them, and in an instant, punched the first one he saw right in the face, sending in flying in one of the walls. Said wall trembled because of the impact, which gave a sudden idea to Saitama. He took a thinking pose as he started to dodge the strikes of the monsters, which only infuriated them more.

"NYAHAH! I GOT IT!!" Exclaimed Saitama, as his face went from bored to serious in a second. His muscles flexed as he took a fighting stance and brought his right fist to his face and the other in front of him.

The monsters had no time to react, a mini crater was made in the dirt, a strong wind passed right by them and a yellow blur appeared in front of them, and then.........

"MUDA!MUDA!MUDA!MUDA!MUDAAAAAAA!" Yelled Saitama, a big smile on his face as he continously punched the poor monsters that suddenly didn't to fight all that much. In a few seconds, only a few dozens of them were left. Saitama saw that and grinned.

"Part 2 of the plan: ESCAPE!!!" Said Saitama, he clenched his hand around the red crystal and suddenly disappeared. Reappearing behind the monster that previously threw his friends at him, Saitama threw a high-kick at him, so powerful that the monster was about to be sent directly out of the tunnel, since Saitama had kicked him in the direction of the exit.

And it was exactly what Saitama wanted. As soon as the kick connected and the monster was about to be sent flying, Saitama used his super speed to grab one of the monster's foot tightly.

"BYE BYE FUCKERS!!!!!" Yelled Saitama as he was sent flying with the monster, who seemed to have lost conciousness. Which was quite normal, since the kick was powerful enough to one-shot anything.

"Damn, they sure fly weeeeeeeeeellllll!!!!!"
