"Sensei !" Genos said as he knocked the door.

Acnologia opens the door.

"So you have arrived." acnologia said.

"Who is that on the door ?" Saitama asked. then he saw genos.

"it's him..." Saitama said.

"I'm genos, saitama sensei." Genos explained his name to them."

"Can you not call me sensei ?"

"Master."

"Not master either !" Saitama replied annoyingly.

Genos sits inside saitama's apartment.

"Go on home after you drink, l'm not looking for disciples. maybe acnologia might accept you." saitama said.

"I am not looking for students either. genos, i see that you are back to normal." acnologia said as he noticed genos's body.

"yes. my body is mostly mechanical, so my parts can be rebundled. what part do you use, master and..."

"Acnologia." acnologia told his name to genos.

"Okay. what parts do you both use ?" Genos asked.

"I don't use any."

"me neither." Saitama and acnologia both replied.

"But how about the ovared skin on your head, master ?" Genos said.

"That's just his skin." Acnologia replied.

"That's odd... master is far too young to be old."- Genos thought.

"So what if i am bald !? What the hell is your problem !?"- Saitama raged at genos.

"My problems ? you want me to tell them ?" Genos said.

"uh... yeah. I think i'll pass. what do you think, acno ?" Saitama asked.

"I think we should give it a try."- Acnologia replied.

"Thank you. four years ago, i was actually a normal human being. although we had to pitch pennies, my family and i lived a happy Life. but that changed when a cyborg attacked our Town one day, destroying everything in our sight. thankfully, i survived. but as a 15 year old weakling, l was alone and the end of my strength in a ruined Town. that's when doctor kuseno saw me. l asked doctor kuseno to perfrom body modification surgery on me. that's how i was reborn as a cyborg who fights for justice. l promised doctor kuseno one day i will eliminate the evil cyborg."- Genos explained.

"We see..."- acnologia said.

"that is-" Saitama was interrupted.

"İt's Been four years since that day. l'm now 19, and i'm traveling from Town to Town to eliminate evil. The numbers of monsters and villains i destroyed are too many to count. But i failed to find Any clues about the cyborg. Then that Mosquito monster arrived and i lost my focus. lf you two, master saitama and acnologia have not been there in the area, i would have been destroyed. master and acnologia, you both saved my life. doctor kuseno saved my life, and you both saved my life as well. l won't be dying as long as i find a way to destroy that cyborg. Last week, i saw your punch. i knew that i had to work under you as a disciple. lf only i became strong as you, saitama sensei !" Genos kept on explaining.

"I think saitama is going to lose it..." acnologia thought in this mind."

"I have an old enemy to defeat, not just for me, for my hometown and doctor kuseno ! doctor kuseno is..." Genos was Interrupted.

"ENOUGH, YOU IDIOT ! SHORTEN THIS STUPID STORY TO 20 WORDS OR LESS !" Saitama raged.

"Things are going to be... Interesting. to say the least."- Acnologia thought.

-Meanwhile, in the house of evolution-

"What are the news, doctor genus ?"- God Serena said.

"Greetings god Serena. Mosquito girl was defeated."- Doctor genus replied.

"She was more than an little prototype after all..." God Serena said as he crossed his arms.

Doctor genus did some research until he found saitama.

"Why is he naked, and who is this guy ?"- Doctor genus asked.

"Well well well... looks like acnologia is back. and he's got a bald imbecile with him." God Serena said.

"These two specimen are interesting... Send them a invitation for them to come to the house of evolution." Doctor genus told to one of his clones.

God Serena walked away and chuckled.

"You're back, acnologia... this time, i will get my revenge !" God Serena said as he smirked.

-Back at saitama's house-

"İn other words, you want to be as strong as saitama ?" acnologia said.

"Yes." Genos replied.

"Genos. how old are you ?" Saitama said with the serious look on his face.

"I'm 19, sir."- Genos said.

"So young... I'm sure you'll surpass me in no time." saitama said.

"You think so, master ?" Genos asked.

"Yes... fine. i'll teach you. but it won't be that easy. do you understand ?" Saitama said.

"Yes sir !" Genos replied.

"Saitama. genos. i sense something." acnologia said.

"what is it, acno ?"- saitama said, then kamakyuri shows up.

"I found you three-"- Kamakyuri was Interrupted with a punch.

"You're going to pay for that ceiling !" Saitama said.

At outside, slurgus and frogman were waiting.

"I don't think i can sense kamakyuri with my telepathy."- Slurgus said.

"wasn't he supposed to be one of our Most strongest agents ?" Frogman asked.

then acnologia leaped down from the apartment and caused a crack on the Ground which surprised Slurgus and frogman.

"This is the end. DRAGON KING'S ROAR !"- Acnologia said as he fired a beam of bright blue energy at Slurgus and frogman.

"leave it to me !" genos then leaped down and saw acnologia wiping out Slurgus and frogman.

"You took care of them already..." Genos said.

"Yes. I did."

"Hey acno, did you..." Saitama Was Interrupted as two arms popped out from the Ground and grabbed his legs before restarining him.

"Master !" genos said.

"nah, it's okay." saitama told genos that it was alright.

"Target found." a voice said. It was armored gorilla and he appeared behind genos.

"A cyborg ? Could it be..."- Genos thought.

"You are not the Target."- Armored gorilla said.

"Hey, what's going on ? I can't see-"

"Get out of the way !" Armored gorilla's blue eye shined.

Then armored gorilla slammed his Fist down on genos, the latter dodged and kicked armored gorilla.

Then Genos rushed to armored gorilla as both clashed with each other.

"I have a few questions to ask you..." Genos said.

Then all of a sudden, Beast King arrived.

"Hahahahaha ! you are in a tight spot, well done, ground drgaon." Beast King said.

Ground dragon popped out from the Ground and said: "İt complicates things if they fight back."

"Master !" genos said.

"You tend to look away ? how rude." Armored gorilla said as he tried to attack genos only for him to incinerate armored gorilla.

"Your attacks have no effect. I am the pinnacle of the house of evolution. i am armored gorilla !"- armored gorilla explained.

"the house of evolution ?" acnologia asked.

"It is None of your business." armored gorilla replied as he rushed towards genos and punched him.

Genos blocked the attack, then leaped and kicked him.

"There is no way out of this..." acnologia thought.

To be continued.
