After mastering the Spirit Transformation Technique and recording the training methods for Ninjutsu such as the Flying Thunder God in the Scroll of Seals, Meikyō left Shadow Clone to train these secret techniques in the Ninja World, while his main body returned to the One-Punch Man World.
Upon returning to the One-Punch Man World, the first thing Meikyō did was naturally to dismantle the Shadow Clone left behind and absorb Shadow Clone memories.
Nothing major happened during this time. The only noteworthy thing was that Saitama said yesterday that he had a dream about a group of very strong Underground People who gave him a good beating. As a result, he actually encountered Underground People after waking up.
However, these Underground People were very weak. After the strongest Underground King was killed by Saitama with a single punch, they raised the white flag and burrowed back underground.
"Smack!"
"Smack!"
"Smack!"
Meikyō was pondering, a series of continuous slaps suddenly came from next door.
"Huh? Saitama is..."
Meikyō drew back the curtains and saw Saitama, wearing a striped shirt, swatting mosquitoes on the balcony next door.
"Aaaaaah! You wretched mosquito, you're not getting away!"
Seeing the mosquitoes wobbling away into the distance, Saitama angrily grabbed the insecticide, jumped off the balcony, and chased after them.
"Mosquito?"
Meikyō couldn't help but think of a strange person who was clearly killed in the second episode, but who frequently appeared in various notebooks.
"It must be her."
Looking up into the distance, countless mosquitoes were swirling in the sky, a sight that could make one's scalp tingle and kill someone with trypophobia on the spot.
"We've finally waited for you. Mosquito Girl, Genos, and... Dr. Genos from the House of Evolution."
Watching the explosions caused by the mosquito swarm in the distance, Meikyō chuckled and jumped out of the window, chasing after Saitama.
"Hey, you, and the one with hair in the back, hurry up and get to the shelter. Those mosquitoes have minds; they'll swarm you as soon as they spot you."
The handsome blond cyborg Genos saw two people approaching and hurriedly gave them a heads-up.
"Oh, then you'd better run."
Saitama pointed behind him with a blank expression.
He knew that Meikyō was quite strong, while Saitama himself was eager to encounter a monster who would give him a good fight.
"Hahaha, two more juice delivery guys here? You better not run away~ I'll come find you after I take care of this guy."
Having absorbed a large amount of blood from mosquitoes and entered its second stage, the Mosquito Girl flew freely in the air, licking her tongue and shouting.
"It's too late, you have to leave!"
Genos gave an order, then turned around, flames shooting from his feet and back, and flew into the sky to fight the Mosquito Girl.
"They can fly! They look pretty amazing."
Saitama raised his hand and looked up at the sky, saying...
"That guy is no match for this mosquito. Saitama, shall we go or shall I?"
"Ah, why don't you do it? It would be too boring if you knocked someone out with one punch again."
Saitama shook his head.
As the two were talking, Genos activated his special technique, "Incineration Cannon," blasting the swarm of mosquitoes into ashes.
Wow! That's amazing!
Within the Meikyō of Susanoo, Saitama sat cross-legged on the floor, clapping his hands.
He really thought it was amazing, because he had been trying to swat a mosquito for ages and still couldn't hit it, while Genos had burned so many to death in one go.
"Could it be a real Flash Mosquito Repellent? One flash and it kills so many mosquitoes!"
Saitama felt he had told a joke, because in Japanese, "flash" and "mosquito coil" sound the same—it was a joke that couldn't be colder.
"Um?!"
Genos only realized now that these two were not normal people.
What normal person would react like this when they see a weirdo?
Just then, a blood-red flash of light ripped Genos's body in two.
Mosquito Girl laughed wildly and extended her sharp claws to chop at Genos's head.
"Oh no, I was careless!"
Genos was startled and prepared to activate the self-destruct program.
"Clang!~"
A long sword gleaming with cold light severed the Mosquito Girl's claw sickle.
"This sword..."
Mosquito Girl quickly flew into the air, staring in horror at the Ama-no-Ohabari in Meikyō's hand.
"This sword, like you, loves to drink blood."
Meikyō chuckled lightly, took a step, and instantly appeared behind Mosquito Girl.
In terms of strength, in the Naruto World, Meikyō's strength is still some distance from the peak of Hashirama Senju, Uchiha Madara, and Admiral Four Emperors, but in the One-Punch Man World, he is enough to rank in the upper echelon among S-Class Hero.
Mosquito Girl's strength is at the peak of the Demon-level, but that is not enough in front of Meikyō.
Genos lay on the ground, watching in horror as the two sides clashed in mid-air.
The previous exchange had already proven that Mosquito Girl's speed far surpassed his, but Meikyō's speed was also far surpassed Mosquito Girl's! Even Genos's electronic eyes sometimes couldn't pinpoint Meikyō's location accurately.
More importantly, the combat skills that Meikyō displayed after countless battles greatly amazed Genos.
Moreover, Genos could tell that Meikyō was toying with that strange man— Meikyō was using Mosquito Girl to familiarize herself with the abilities she had recently acquired.
The ultimate application of Observation Haki: the ability to briefly Future Sight.
"Hey, are you alright? Do you want me to help you put it back together?"
Saitama walked over to Genos and poked Genos on the head.
He's still holding insecticide in his left hand and wearing slippers.
"If possible, please hand over my lower body."
Genos paused for a moment before speaking.
"Also, could you tell me about the identity of the powerful figure who fought the monster?"
"Ah, you mean Uchiha Meikyō? He said he's a hero like me, but when he introduced himself, he said he was a ninja who also worked as a swordsman."
Saitama touched his smooth head and chuckled sheepishly.
"Hero? Ninja? Swordsman?"
Genos looked up into the air, his eyes deep and thoughtful.
"Boom!"
Mosquito Girl had her wings and limbs severed by Meikyō's sword, and was slammed heavily to the ground, creating a large crater.
After exchanging a dozen or so blows, Mosquito Girl had already met this end, and this was only Meikyō deliberately held back, afraid of killing Mosquito Girl.
"No!"
The Mosquito Girl's beautiful face was filled with fear, but with her limbs and wings broken, she was powerless to do anything.
In the critical moment, the Mosquito Girl's body suddenly exploded, turning into countless blood-red mosquitoes that scattered in all directions, attempting to escape.
Fire Style: Great Fire Annihilation!
A raging inferno erupted, the terrifying heat scorching every single mosquito.
At this moment, driven by instinct, the Mosquito Girl merged together once again.
A single mosquito's strength is insufficient to withstand such high temperatures; she must gather her power to revert to human form, and the price to pay is—
"Ninja Technique· Four Symbols Seal!"
Meikyō placed his palm on Mosquito Girl's chest, and black runes spread out, sealing the energy around her.
At that moment, Saitama and Genos, who was dragging his broken body, arrived at Meikyō's side.
"Hey, mosquito, why don't you swat it?"
Saitama looked curiously at the Mosquito Girl on the ground, whose limbs and wings were severed and whose body was covered with Cursed Mark.
"I'll keep her; she'll be useful."
Meikyō replied.
"Oh, I understand, but you still need to be moderate! Since I started exercising, I've completely given up those things for the sake of self-discipline. Meikyō, if you want to continue to improve, you also need to restrain yourself in this area!"
Saitama looked at the hand that Meikyō had not yet withdrawn from Mosquito Girl's chest and suddenly Satori.
Meikyō's lips twitched slightly.
"That's not the usage you're talking about!"
"My lord, if you wish, I am also capable of doing so. Submitting to a male stronger than oneself is only natural, isn't it?"
Mosquito Girl winked at Meikyō and licked her lips as she spoke.
It's clear that her will to survive is very strong.
"You have no right to speak here."
Meikyō opened his Mangekyō Sharingan and glared at Mosquito Girl, putting her to sleep.
"Ah, it's all done, Meikyō. Take your inflatable doll and let's go home for dinner. I still have some leftover Udon from last Saturday's supermarket clearance sale."
Saitama waved his hand, as if to leave.
"Please wait! Mr. Meikyō! Please accept me as your disciple!"
Genos, who was welding the broken body with a robotic arm, suddenly stopped and said...
"Um... but Saitama is taller and stronger than me, you should become his apprentice."
Meikyō pointed to a bald man and said.
He is Genos's destined teacher.
"Please, both of you, accept me as your disciple!"
"Huh, huh?"
Saitama looked completely bewildered.
"Hey, hey, hey! Meikyō, stop pushing all the trouble onto me!"
Saitama, just like in the original timeline, did not accept Genos at first—because he thought it was a troublesome matter.
Meikyō did not object to this.
Although Genos is known as the "Invincible Myth," his strength is still considerable. At least for now, he possesses the strength equivalent to an ordinary Demon-level monster. After being upgraded in the future, he will be able to contend with some Dragon-level monsters, making him a top-tier fighter in the One-Punch Man World.
If Meikyō wants to do something, having Genos around can be a great help.
So, after a relentless pursuit, Genos moved to the room next to Meikyō, opposite Saitama.
In Meikyō's basement, a makeshift prison cell was created to satisfy sexual desires—no, I mean, torture chambers.
"Hey, you're awake now, right?"
Meikyō crossed his legs, sat in a chair, and spoke to the Mosquito Girl who was tied to the wall in front of him.
"So, adults like this kind of thing? Although I'm not playing a role I like, it's not unacceptable, is it?"
Mosquito Girl opened her eyes and licked her sexy little tongue as she spoke to Meikyō.
Meikyō:...
"I want to know the location of the House of Evolution."
Meikyō spoke coldly to Mosquito Girl.
"Do you know my background?"
Mosquito Girl seemed a little surprised.
"Then you should know that there are several stronger fighters than me in the House of Evolution, right? You shouldn't need to worry anymore. A tracking device has been implanted inside my body. If nothing unexpected happens, Dr. Genos should soon send other high-ranking fighters from the House of Evolution to capture you and conduct experiments on you. Of course, if you could release me and we could switch places so I can feel more comfortable, maybe I'd plead for you."
Mosquito Girl spoke to Meikyō in a charming voice.
"Ah, it seems unnecessary."
Meikyō suddenly raised her head and looked up.
A Mantis Monster broke through the roof, only to find a long sword held across its neck.
The mantis's head was cut off on the spot.
"Besides."
Meikyō smashed through the roof with a single punch and Body Flicker Technique disappeared.
Hearing the commotion next door, Genos quickly used his bio-radar to scan the area and also discovered several strange figures hiding in the street.
The engine started, Genos broke through the window, seeing four strange figures outside.
A Katsuyu, a frog, and a tall, steel robot.
Further away, Meikyō was fighting a gigantic humanoid lion.
"Machines modified into humans?"
Genos's eyes instantly turned dangerous.
Four years ago, he became an orphan because of a rampaging cyborg. After being rescued by Dr. Kusuno, he took the initiative to request that his body be modified, and except for his brain, his whole body was made of machinery.
"Hey, who are you people?"
Genos's palm lit up, and he pointed at the robot in front of him.
"Our mission is to bring you back to the House of Evolution, as instructed by the doctor."
The tall robot slowly walked forward and said.
Beneath this thick layer of steel lies a bio-engineered Masira.
He just thought it was cool to talk like a robot.
Genos begins his battle against the Mecha Gorilla.
As for Saitama.
"Hey? What's all the noise? Are they fighting? Is there some weirdo around?"
A shiny bald head popped out from the balcony.
"The black-haired one can beat Mosquito Girl, so we'll leave him to Beast King. The blond one will go to Mecha Gorilla. As for the bald one, he looks unremarkable and is probably the weakest among them, so we three will take care of him!"
The Frog Monster stroked his chin and said.
Meanwhile, the Earth Dragon has burrowed underground and begun its attack on Saitama.
He is a groundhog with an extremely strong ability to burrow underground.
Saitama, who didn't take the monster's attack seriously, was pulled into the ground by the Earth Dragon, with only his head sticking out.
"Hmm... it feels a bit strange. It's cool and refreshing down there, which seems quite comfortable."
Saitama tilted his head, still with a naive smile on his face.
"Hmph! Feeling the despair now, huh! Baldy, you'd better just submit and become our hostage!"
The Frog Man stuck out his long tongue, crossed his arms, and said smugly.
"Hmm... this seems even stranger. Ah, so some soil has fallen into this strange place."
Saitama burst out of the ground and unbuckled his belt in front of the three monsters with a very open and honest manner.
The Katsuyu- like monster blushed and turned away.
She is a female monster.
A "#" symbol appeared on the Frog Man's forehead.
"Hey! You bald guy, didn't you hear us?! I'm going to gouge your eyes out!"
