Chapter 1: Sale

Saitama made it, he finally made it to the sale on time.

Recently, many monsters and beasts have started to appear in his area. And somehow, he always ends up fighting them.

They hinder him from getting to the sale on time, and before he knows it, it's already over.

He has started to grow angrier as this goes on.

But finally, he did it.

"All those freakish monsters are annoying, I'm glad the sale was still going on."

As Saitama walks home with his groceries in hand, a large freakish monster appears before him. It had long tendrils and horns all over its body. Big and bulging yellow eyes and a small purple hue to its skin.

"KEKEKEKEKE! Stupid little bald man...OH!~ were you expecting to go home and eat those recently bought groceries?....FOOLISH! KEHEHE!"

One of the tendrils was launched toward Saitama's bag of groceries.

Suddenly, the tendril was turned to nothingness in a second.

"How dare you. HOW DARE YOU TRY TO DESTROY MY FOOD FROM THE SALE I WORKED SO HARD TO GET TOOO!"

"H-Huh??....human....what...what is this sudden force being put on me? I feel like my death is.."

POW

All it took was one punch for the tendril monster to be defeated.

Saitama went home and enjoyed his food from the sale.

--

"Genos. Show me another robot skill."

"Master. Anything for you!"

Genos, the S-Rank Hero known as Demon Cyborg opens a latch in his chest and opens his mouth.

A beam starts to charge up and he spreads out his arm small latches opening there.

He blows the beam into the air with small amounts of force and water dispenses from his arm, creating steam that turns out to look like Saitama.

"I hope you were satisfied with that, master."

"That was pretty cool Genos!"

Genos looks at Saitama, "Master, have you noticed the sudden rise of monsters recently?"

"So I'm not the only one? Those little bastards are stopping me from getting to the sale on time."

"Something is happening and on the move. The hero's association is currently trying to figure out what's happening."

Saitama picks the wax from his ear, "Good. We need to eradicate them or else I might never be able to make it to the sale on time."

A sudden pounding sound could be heard slowing creeping in.

Both of them noticed this and started wondering where it was coming from.

Suddenly the top of the building they were in was taken off. 

A giant eyeball peeked into the building, and Saitama just stared at it blankly.

"Seriously?"

The monster spoke weirdly, it sounded like a baby choking that was also trying to speak.

"Killll~"

It was a huge monster, at least bigger than half of his city.

"Tch! Master, get ready! I'll call in a few S-Ranks.."

"No need. I'll handle it quickly. I'm in a bad mood and just can't stand it right now."

Killer Move: Serious Series, Serious Finger Flick.

A flick of Saitama's finger made a large gust of wind so strong it made the monster fly backward and tore off a portion of its body.

"GHHHHA!"

"I'm not in a good mood right now, so I'll finish this quickly."

Killer Move: Serious Series, Serious Air Blow!

Saitama breathed in quickly and slowly released his breath at the monster.

It put a gigantic hole directly through it.

The monster quickly dies.

Saitama sighed, "My house.."

--

"The preparations are complete. All of the monsters under our wing have evolved in at least dragon threats. And our strongest monster, MALIS. Will surely cause the hero's trouble."

A man in a long coat with an eyepatch has an evil smirk on his face as he speaks to a small boy.

"And you, Hirako, will be my greatest piece yet even stronger than Malis."

"F-Father...don't...I"

"Silence. You will succeed me and kill those filthy heroes!"

Hirako goes silent as he just looks at the ground. 

"Henry! get in here. Get the accelerator ready, it's time."

After the accelerator room was prepped, the man took his son tied him up quickly, and made him swallow something that was starting to make him shake and foam at the mouth.

He watched behind some glass as the accelerator was charging up ready to hit his son.

"Don't worry, it'll be worth it in the end."

Hirako was completely passed out, and then a strong beam struck him in the chest and his veins started to glow.

His body was progressing fast.

He had become a teenager, and then an adult in just minutes.

His hair turned a crimson red color, his eyes glowed a golden color, and his body was surrounded by some type of dark matter like an outfit to his body.

"It worked...It worked...."

As Hirako stepped, everything around him started turning to nothingness and disintegrated.

Hirako looked at himself, was this truly him?

An overwhelming power flowed through him. He wore dark matter like a suit and every strand of his hair had supernova levels of strength inside of them that only made him stronger and his golden eyes allowed him to see the future and even determine any and everything.

"My son, you....have made me happy."

--

A strong beast was now running rampant.

It had a humanoid form but wasn't human.

It had sharp horns, and spikes etched all over its body like armor and had a bright purple glow to it.

Watching from afar was the eyepatched man, "Malis has been sent out to see the world, chaos will now take over!"

Malis used a dark sword of energy, inside the sword small little false stars and bright lights could be seen.

With one swing of the sword, it destroyed everything, turning it into a dark energy before dissipating into the air.

"I, am Malis! I will plunge the world into darkness and rule! Bow to me!"

S-Rank heroes had already arrived.

A large building was thrown at Malis while he was restricted by a strange power.

"URK!....What?.."

A green-haired girl floated down from the sky. She looked like a child but was an adult. It was S-Rank Tasumaki, Terrible Tornado.

"Who do you think you are? Just die already!"

Tatsumaki twisted the monster's body with her powers, but it resisted and managed to break free from her psychokinetic powers.

"Foolish little girl."

Malis dashed at her, gripping her head in the blink of an eye, and slammed her to the ground. He runs her through the stones and floor.

"I'm....not...A LITTLE GIRL!"

Her power grows stronger as she uses it to push Malis backward.

"I see. You are dangerous so I must kill you."

He raises his hand, a dark energy forming into a sword.

Disappear.

He slices the air, and everything the energy touches fades into nothing very quickly.

Malis swings and swings, and Tatsumaki does everything to not be hit. But she could feel herself growing tired.

But she hadn't given up yet, she used her powers and focused everything on Malis's arm.

She twisted it so much it was hanging off. But he had no blood and no bones, he was energy itself.

"Tch.....!"

Malis punches Tasumaki in the gut, sending her flying into a few buildings, and she fades into unconsciousness. 

"I put nearly 4000 tons of power in that one punch, she shouldn't wake up for a bit."

"Hm?...who are you?- SERIOUSLY? My house again..!?"

'Who is this bald man? I sense nothing from him. Whatever doesn't matter, I'll quickly kill him.'

Malis charges up a small blast with his hand, shooting it at Saitama.

'Now, let's get going!' Malis was ready to shoot off.

"Hm?..." Saitama just stood there, undamaged with a blank stare.

'What the!....just one of those blasts can destroy an entire city with minimum effort...and this baldy isn't even fazed by that?...'

Saitama glared at him, "Why is everyone destroying my house?....."

'What....is this aura?... this intense force is overwhelming. I-I have to kill him!'

Malis jumped in the air, raising his arm and charging a large slash.

"DIE!"

The slash cut through every building in a 100km radius perfectly. But Saitama just watched as the slash moved almost as fast as a turtle, he dodged it quite easily.

"You hurt that little girl over there. She's strong for being so small, yet you just crushed her dreams! And lately, I've been in a bad mood. So I'm gonna put some force into it."

Killer Move: Serious Series, Serious Axe Kick.

Saitama burst into the air and raised his leg, he quickly slammed the kick onto Malis's head.

The kick went through Malis's body, tearing him right in half. 

Saitama then just does a normal punch, the vast gust of wind was so strong it finished Malis off.

"I feel bad for that little girl.."

Saitama then heard someone walking, "I'm....not...A LITTLE GIRL!"

"Oh, you're awake." Saitama had a blank smile on his face.

"Shut up baldy! who even are you?! And who killed that monster? another S-rank must have come and handled it quickly."

--

"As you all know, random monsters have started to appear. But they're nothing to be made fun of. They are strong, at least all demon or dragon level, or maybe stronger than that. We already have multiple A-S Ranks heroes on standby."

Another man speaks up, "Recently a dragon-level threat was discovered in city Z it practically destroyed everything in a 100 to 200-mile radius. It called itself Malis. But, it was defeated. We believe S-rank Terrible Tornado managed to defeat it as she was in the area."

The man standing at the end of the table nods and goes back to talking, "Get as many heroes as possible on standby. Who knows when an even stronger beast will return."
