Saitama muttered a bit angrily under his breath as he was sitting on the couch and trying to open a bag of chips. He had remembered that one time when he had accidentally caused Genos to lose a portion of his memory because he had accidentally hit him.

Surely, he didn't want to repeat the same mistake again. He eased the force a bit on the bag of chips and got to thinking.

Hmm...I can pull the bag apart to open it because if I do...everything will go flying, but yet again, do I need to pull the bag apart. Hmm...oh, I know what I can do.

Saitama places his thumb and finger on opposite sides on the top of the bag with one hand and does the same thing with his other hand. He then begins to gently rip the bag in half.

Yes...THIS IS GOING TO WORK! CHIPS! MY CHIPS!

Saitama accidentally miscalculated the force he needed to rip the bag and accidentally ripped the entire bag in half, causing chips to go flying.

NO!

Saitama casually grabs every single chip that flew in the air and sat back down on the couch. He seemed annoyed.

Ugh...that was close.

Saitama grabbed the remote and turned on the TV. He was beginning to get bored again. He didn't have anything to do since Genos was called in for something by the Hero Association. They didn't really need Saitama for anything currently.

Should I go to the movie theaters or something? Maybe I should check to see what King is doing.

He began watching TV and noticed the many reports of monster corpses lying on the ground with their limbs completely missing. Saitama raised his eyebrows.

"Who could've done that?" Saitama said to himself. He scratched his bald head. Since he had nothing to do, he might as well go outside for a stroll. After all, the trees seemed to be blooming.

Saitama casually got up from the couch and stretched. He glanced at his hero jumpsuit and decided to leave it alone. He didn't really need to wear it today anyway.

He grabbed his wallet and strolled out of the apartment, thinking about what he would be doing for the rest of the day.

...

Saitama was roaming the corridors of the Hero Association HQ. He was beginning to think that King was probably not in the Hero Association building, so he had some other ideas on where King might've been.
Probably at the arcade or something...might have to go there in order to find him...

Saitama turns around and waits for the elevator doors to open. When it does open, he spots two roughed up heroes in the elevator. He raises his eyebrows.

"So, looks like you guys got in some stuff..." Saitama said plainly. The heroes frowned.

"Dammit! We could've had that monster, but I'm grateful to be alive anyway." One of the heroes said.

"Yeah, definitely." The other said.

Saitama was confused.

"Oi, what do you guys mean by that?" Saitama asked. The heroes looked at each other and looked back at Saitama.

"The thing or hero that defeated the monsters for us is unknown. The association can't pin down who was responsible for the killings." One of the heroes said.

"Ah...I see. Maybe it was Genos?" Saitama asked, brushing his chin. The heroes shook their heads.

"You mean the Demon Cyborg? No, it couldn't have been. He was sent out to find out what hero or thing could've done that, because apparently, it wasn't the doing of any S-Class Hero..." The other hero replied.

Saitama nodded.

Oh...so that's why Genos was out: so he could find out who killed the monsters.

Saitama watched as the heroes stepped out of the elevator and Saitama stepped in.

"What are you planning on doing?" One of the heroes asked.

Saitama shrugged.

"Don't know, maybe I'll go on a hunt for whatever thing did that to those monsters. Say, is there money on the line for it?" Saitama asked.

"Uhh...NO! DEFINITELY NOT! THERE'S NO MONEY..." One of the heroes said. The other hero hit the one that spoke on the shoulders.

"Nah, he's just joking, there is—a lot of yen, the only reason why we're back at base is because we can't fight. We've used up everything that we have. It's not like we were ever going to discover who did that to those monsters anyway..."

"Hey! Don't say that! We were close! SO CLOSE!" The other hero said.

They continued to argue, but their argument faded in the back of Saitama's mind as the elevator doors closed and Saitama was going down. Saitama still had his hands his pockets.

...

A small park in City A was devastated. Benches were crushed or overturned, and picnics were completely ruined. The monsters continued their onslaught—killing and ripping apart any human they could find.

On a hill, a group of monsters were toying with an 8-year-old boy as he cried and looked at his parents' corpses. The boy continued to cry and the monsters casually pushed and shoved him around the corpses of his own parents.

"THAT'S RIGHT! KEEP CRYING! COME ON! I LOVE THE SOUND OF THAT!" One of the monsters said playfully. The boy stumbled on the ground face-first, tears still flowing down his face.

He slowly looked up and saw a cat approaching him. His heart skipped a beat.

"NO! RUN!" The boy screamed at the cat. The monsters stopped their laughing and glanced at the cat that was approaching them.

"Oh...look at that...a little pussy is approaching us. Let's give it a A WARM WELCOME!" A monster screamed, charging at the cat.

The other monsters charged at the cat too and the boy closed his eyes. He didn't want to see how the monsters would utterly slaughter the poor cat. Just the sight of his parents' corpses were enough.

The boy began to sob even more. He continued until he heard weird crushing sounds followed by the sound of meat landing everywhere. He slowly opened his eyes and saw a pile of blood, guts, and limbs everywhere. The boy seemed perplexed.

"W-what?" The boy said, sniffing. He squinted his eyes and saw the cat that he was sure had been slaughtered completely fine, but covered in blood—monsters' blood. The boy was so shocked that he immediately stood up and started walking backwards.

"No...did you...do this?" The boy asked the cat, well aware that it couldn't speak. To his surprise, the cat said "meow" and started going in the opposite direction. The boy let himself fall to his knees and stared at the cat as it strolled away, knowing well enough that it had been the cat who saved him.

...

Within the denser parts of City A, where more monsters were wreaking havoc, Genos soared from building to building, eliminating any monsters he could find on sight.

He had managed to eliminate a good amount ever since he went on the lookout for the mysterious being that managed to casually defeat four Demon Level monsters out of nowhere, according to the Hero Association.

What was even more perplexing to Genos had been the initial discovery that it wasn't the doing of any S-Class or A-Class Hero. It also wasn't Master Saitama's doing because he was chilling in his room when Genos got the current news. So...who couldn't have been.

This is of great importance. Besides, there's money behind it. Master could really use a bit of that for himself too. I really hope I find whoever did this.

Genos continued to jump from building to building, while he was going he managed to catch a glimpse of Fubuki and her gang driving through the city. Genos stopped and analyzed where they were going. It looked like they too were in it for the money.

"I guess most S-Class Heroes don't really care about the bounty. They probably see it as a waste of time. Most of them are rich anyway, so that's not surprising." Genos said to himself.

Genos glances down and spots a cat roaming the parts of the city block completely unharmed. He leaned back in surprise.

How? How did a cat manage to survive all this? So many people have died...and yet...a single cat is just casually strolling?

Genos leaps from the building and starts descending. He keeps his eye on the cat as he lands on the sidewalk with a loud bang. He sits up and stares at the cat, scanning its skeleton to make sure that it's not a monster.

It looks like a normal cat to me. Nothing out of the usual...so why is it that I feel like this thing is the reason behind everything?

Genos takes a step closer to the cat, but the cat glances back at Genos. Genos frowned. He took more steps closer to the cat until he was standing right in front of it. He kneeled.

Before Genos could say anything, he could clearly see the cat about to scratch him. He quickly detected immense energy behind the cat's swing and effortlessly dodged it.
The cat missed and managed to slice an entire building in half—clean cut. Genos's eyes were on fire.

"I SEE! SO YOU'RE THE ONE BEHIND IT ALL!" Genos proclaimed, standing his ground.

"MEOW!" The cat replied. Genos frowned. He dashed at the cat.

"I WILL TAKE YOU IN! YOU CANNOT ESCAPE ME!"

Genos said, shooting energy beams from his incineration canon. Each energy beam destroyed a large part of a building or sidewalk, and the cat was dodging them like it was nothing.

Genos ran so fast he teleported behind the cat.

"MACHINE GUN BLOWS!" Genos screamed, punching at the cat very fast. The cat had managed to dodge Genos's attacks and slice Genos's arm off. Genos's left arm went flying away.

NO! I WAS TOO RASH!

Genos leaped backwards and dodged some of the cat's slashes as they continued to cut through anything that was in their way.

What should I do? I'm out of options...the only thing I can possibly do now is to blow up the surrounding city blocks...but...what if they're other heroes and civilians around?

While Genos was too busy in his head, the cat sliced in his direction again, and this time, Genos couldn't dodge. The slice had managed to chop both of Genos's legs off and he couldn't move.

Agh!

Genos collapsed on the cracked concrete. The cat had made another slash and Genos closed his eyes, only to open them up again and realize that he hadn't met his demise.

"Master?" Genos said, but he was wrong. When he looked up to see who had saved him, he realized that it wasn't Master Saitama but the green-haired spoiled brat—Tatsumaki.

Tatsumaki glanced at Genos as both of them hovered above the buildings—Genos being carried by a green force field.

"Useless...you can't even hurt a kitten and you call yourself S-Class? You're such a disgrace..." Tatsumaki said. Her green hair glowed as she began to display more of her psychic powers.

The city blocks began to crumble under her sheer presence. The cat ran away so fast that it left a large dust trail in its wake.

Tatsumaki was genuinely surprised by its speed.
"Hmph...faster than a thought..." Tatsumaki said to herself.

She envisioned the entirety of A-City, including its sewer system, and yet, she couldn't sense the cat anywhere. It's almost like the cat was immune to her abilities. Interesting—it managed to cloak itself somehow.

Tatsumaki sighed.

"Well...it's lucky it got away." Tatsumaki said. She turned around and glanced at Genos.

"You should be ashamed...whatever, you got lucky that I decided to head out. The next time you're in trouble, be strong enough to help yourself." Tatsumaki said plainly.

With that, she flew away with Genos towards the Hero Association HQ.

...

Saitama was strolling through City A. He had already punched about twenty monsters during his time out, and he still couldn't fathom the idea of someone else doing someone similar if it wasn't Genos or possibly the S-Class.

Man...this is too much for me. My clothes are mostly covered in blood and there's fire everywhere. I guess I should've just stayed in my apartment room—maybe that would've been the better choice.

Saitama finds himself walking across the street. He looks up and sees another monster looking down on him.

"Oi...sup." Saitama said casually.

The monster grinned.

"BOW TO ME BALDY! BOW BEFORE—"

Within less than a second, Saitama's fist was already in the air and the monster's upper body disappeared. The lower body fell with a thud and Saitama sighed.

"Now I got more blood on my shirt..." Saitama said, looking at his shirt.

He turned around and saw another monster shocked—most likely because they had seen what he was capable of. Before Saitama could punch that monster, he saw the monster get chopped up into ten pieces. Saitama stopped in his tracks.

Oh...so is it that middle-aged guy?

Saitama thought, but he then realized that he was completely wrong. What was behind the monster corpse was a cat that was partially covered in guts and blood. Saitama raised his eyebrows.

Saitama made a small plain and nonchalant smile towards the cat.

"Oi...did you do that? Wow, you're strong." Saitama said plainly. The cat didn't reply.

Saitama approached the cat and kneeled.

"So you're the one who destroyed those monsters, huh? You're very similar to that black dog I have. Well, Fubuki has it over at her place. You guys would definitely make a great team." Saitama said plainly.

The cat purred around Saitama's gentle touch. He sighed.

"Don't worry. Your secret is safe with me as long as you don't do anything crazy, okay?" Saitama said.

"Meow!" The cat replied. Saitama stood up and started walking back in the direction he came with the cat by his side.

He could've turned the cat in and got some yen, but did he really want to do that? He could always ask Genos for yen anyway. Maybe having a cat around wouldn't be so bad anyway.

...

Some Hours Later

Genos is chilling in Dr. Kuseno's lab. He's recharging and thinking about the encounter he had with the powerful cat. How could he have even screwed that up so badly? He had the thing right in his grasp, and he had overestimated his abilities to restrain it, which led to his demise.

What will Master think if I told him I lost to a cat? Would he still see me as being worthy to rival him one day?

The thoughts continued to swirl and wouldn't stop. Genos glanced at Dr. Kuseno who was welding something in the background.

"Hey, Doctor..." Genos started.

Dr. Kuseno stopped welding and looked at Genos.
"What is it...Genos...?" Dr. Kuseno asked.

Before Genos could say anything else he heard the automatic doors to the lab open and saw Master walking in. He gulped.

Oh no...I'll have no choice but to tell him...

"M-Master...it's not what it looks like..." Genos began, but he stopped speaking and was shocked to see that Saitama was walking with the same cat that had almost killed him.

"Huh? Hey, Genos...what happ—"

"MASTER! STAY BACK! THAT THING IS DANGEROUS! IT PUT ME IN THIS CONDITION!" Genos screamed.

Saitama raised his eyebrows and looked at the cat. He was utterly confused, then, put the pieces together.

"Did you try attacking this thing, Genos? Oh...I see. Well, it's nice now, it won't do you any harm..." Saitama replied.

Genos was still filled with caution.

"Master...I do not trust that thing..." Genos said.

The cat hissed.

Saitama patted its head.

"Hey, Genos, it meant no harm. Maybe it was just scared. Anyway, the good thing is that you're okay." Saitama said.

There was silence between them, then, Genos spoke up.
"Did you report it, Master?" Genos asked.

Saitama shook his head.

"Uh...well, you see, I made up a lie. I found a lot of, well, I guess high ranking heroes on the ground—defeated. They were probably A-Class Heroes, and I saw a monster hovering over them. I then saw the Atomic guy and he approached me after killing the monster. Um...we made a deal to trick the Hero Association into believing that the monster he had killed was the monster that was wreaking havoc, and we used the pile of A-Class Heroes as evidence. The deal was settled so long as I got to spare the cat. The Atomic guy would get all the yen. And yeah, that was pretty much it..." Saitama said plainly.

Genos frowned.

"Keeping secrets from the Hero Association? Master...are you sure this is alright? To think the S-Class would go against the Hero—"

"Meh, it was nothing really. It wasn't even that big of a deal. The point is, I get to keep the cat now since they don't think it's a threat. So, Genos, what should we name it?" Saitama asked nonchalantly.

Genos was in deep thought, then, he had an idea.

"Razorclaw, Master." Genos replied.

Dr. Kuseno nodded.

"Nice one, Genos." Dr. Kuseno said.

Saitama sighed, a little annoyed that Genos was able to come up with a better name for a cat than the Hero Association could come up for him as a hero.

Dammit! RAZORCLAW IS SUCH A COOL NAME! WAY BETTER THAN THE CAPED BALDY!
