...


Piling the rubbles into one, humongous spherical object, Gyoro Gyoro exerted all of his psychic force into amplifying the pressure by a hundred fold down into the center, aiming to turn the person inside into a mushed, condensed meat.

However, all of his efforts proved to be futile when simultaneously, all the rubbles were plunged away into the every direction. Among the dispersed smoke, a figure levitated in the air, the three protrusion extending from her waist began to flutter wildly as the wind brushed against it violently.

"Is that all you've got?" Tatsumaki taunted, her blazing eyes sunken into every barricades of courage that the monster had possessed earlier, it's piercing gaze shaking his determination.

With a single swift of her index finger, her psychic energy was enough to penetrate the spherical barrier that Gyoro Gyoro's encapsulated himself around with.

To know that the Tornado of Terror posseses such an unquantifiable output of psychic prowess...

"I'm not pretty keen on giving bloated cretins like you second chances, but you seem to be tugging at my sympathy with the pitiful state you're in," Her eyes glinted, shimmering with an all-encompassing wrath, "Tell me about the whereabouts of my sister, and I'll leave. Of course, you'll still have to deal with the other heroes, but I doubt you'd last even a second against them. They're nothing to me, but they're pretty strong in their own way. You're fucked either way, so might as well spill the beans."

"Are you daft?!" Gyoro Gyoro screamed, "I already told you, we have no-"

She clenched her fist, tightening it as the psychic force within her behaved the same, squeezing the monster's arm into a meat pretzel accompanied by a blood fountain.

"You ordered your boot-lickers to search for her, did you not?"

"Y- yes, but they haven't found her yet!"

"THEN TELL THEM TO SEARCH FASTER!" Tatsumaki pinned the monster against the wall with her psychic powers, "I'll demolish this whole city if I have to! Casualties be damned! My sister is the only thing that matters!"

Gyoro Gyoro only let out a suffocated groan, unable to mobilise himself and break free.

Loosening the pressure that her powers exhibit, Tatsumaki spoke again, "Speak."

Coughing, Gyoro Gyoro opened his mouth, "I'll make you pay for this impudence..."

"I didn't tell you to bark, I told you to provide me intel." Tatsumaki's brow furrowed, as her fist clenched a bit more, putting more pressure into the monster, "Or is being a dog all that you're good at?"

"So that's how it is," Gyoro Gyoro's lifted his gaze to the massive structures above, before..

"OROCHI-SAMA! I HAVE YOUR PREY WAITING FOR YOU HERE! YOU ARE UTMOST WELCOME TO DEVOUR HER!"

A few seconds passes...

No response came..

"What?! Orochi-Sama-!"

"Orochi, huh?" Tatsumaki raised her brow, piquing her interest, "Is that the main culprit behind this whole Monster Association thing? Perhaps he knows about my sister."

In other words, Psykos herself.

"Or maybe he's dead." Tatsumaki added.

"Dead? But how could anyone-?!" Then, something clicked inside his mind. The mental image of a man wearing a yellow jumpsuit amidst the mist, blood tainting the fabric of his outfit, and in front of him, laid the corpse of his grand master. His ultimate creation.

No..

It can't be...

"Getting a cold feet already?"

"NO!" Suddenly, Gyoro Gyoro's aura erupted outwardly, pushing Tatsumaki slightly.

"That's a new one." Tatsumaki remarked.

Exuding an enraged outcry, multiple eyes began to emerge in every area of his body, "I'll rain down every agony imaginable upon you and your wretched fellow heroes. NOW SUBMIT! GRAVITY AMPLIFIER TIMES THREE HUNDRED!"

Tatsumaki was catapulted downwards, forced to stand on the collapsing ground. But to the monster's dismay...

She remains unbothered.

Stretching her shoulders, she spoke, "Surprisingly, this feels good. My shoulder's been feeling all stiff lately. Perhaps a little bit more pressure on the left?"

"DAMN YOU!!!"

Gyoro Gyoro's body began to twist itself, as a fountain of blood began to form, each of his limbs exploding subsequently. His agonising shriek echoed throughout the base.

"W- woah! Ahh! No! Woah, woah-"

"Shut the fuck up!" Tatsumaki slammed the monster into the ground with a single swipe, "Did your subordinates find her yet?"

"No-!"

Tatsumaki twisted her fingers again, causing his other limb to explode in a rain of blood, "For every minute that we waste without any viable updates, each of your limbs will explode. Now imagine the hassle when you operate without your precious arms and legs?"

T- this woman is insane! Unhinged! Deranged! Sadistic! I- I- I can't believe I thought of myself the epitome of wickedness, but this woman goes well beyond that!

"Of course, I can rearrange your missing limbs back." Tatsumaki's hand lifted, as the remains of both the monster's limbs began to rearrange itself, subsequently reattaching it into it's original place, "Don't worry, I can do this all day."

Before Gyoro Gyoro could speak, suddenly...

"No..."

"What?" Tatsumaki raised her brow.

"The Heroes are here." He said, "Therefore, the search for your sister is disrupted."

Tatsumaki didn't take this information very well.


...


"This place is narrow, reeks of dogshit," Atomic Samurai remarked as he took a glance around the narrow space, "Are you sure that child didn't make any sort of blunders?"

"This is the only lead that we have, master." Another man wearing a black sleeves shirt underneath the sleeveless medieval armor and a helmet said.

"Hm." Atomic Samurai hummed, chewing on a thin splinter, "It's hard to believe that a place of this likeness is the residue area for an organisation as grand as the Monster Association."

"Perhaps if we dive deeper, we could see it's enticing side." Iaian remarked.

"Or the testament to it's lack of sanitation." Atomic Samurai waved his hand around his nose, "They have no awareness when it comes to being organised."

As they walked, they halted when they were presented with two separate pathways. Atomic Samurai pulled the navigation device out of his pockets, "Says the two pathways may lead to the same destination."

"Should we separate for now, master?" Iaian asked, and by the looks of it, his other companions inclined to agree.

Atomic Samurai raised his brow, "Didn't the director said to maintain teamwork and avoid segregation at all costs?"

"I'm aware but..." Iaian bowed his head, "I want to see how well I would fare against the obstacles presented in front of us without your aid. It would do very well to our progress as your disciples."

"This self-training you're trying to impose on yourselves will risk the completion of the operation." Atomic Samurai said, "Now I'm not calling you weak, but it would be better if we stayed with each other."

"Master." He said with a sardonic tone, "Please. You would do us a favour if you allow us to."

"..." Atomic Samurai gave them the silent treatment, tapping the floor as his eyes landed on the ceiling above.

Persistent, aren't they?

"Fine. I will grant you permission that you so desire." Atomic Samurai then lifted his hand before they could rejoice, "Under one condition." His eyes sunken into theirs, sternly stating, "You are to update your status using your provided transmitter device every few minutes."

"Yes, master!" All of them shouted in unison.

Atomic Samurai simply huffed, as his attention returned back to the two pathways, "Take the right flank, while I go to the left."

"Yes, master!"

Then, they went their separate ways. Calmly, Atomic Samurai scanned the area, which, the longer he walks, the more gradually narrower it becomes. Quite unsettling, if he say so himself.

Then, his mind lingered at the thought of the new enigma, Midoriya Izuku, the kid that barged into their mission so carelessly. What were the Commission thinking, bringing along an inexperienced brat into a field that he very well doesn't belong in?

Perhaps he could be a prodigy, but that's beside the point.

Even if he possesses a quirk beyond those of an average pro-hero, he would still need the required experience to accommodate his competence.

"I hope that brat doesn't get in the way of the mission and become a liability." Atomic Samurai said to himself with a long-suffering sigh.

"Bold words coming from a soon-to-be sandbag."

Atomic Samurai could sense the presence immediately, and without so much as a slight visible movements, dozens of slash lines were formed in the air.

The anonymity, however, quickly recovered, the wounds inflicted in it's flesh quickly healing, "Huh? The fuck, didja just slash without moving? Practicing form over substance, are we now."

The amber flame resembling a katana dissipated into his palm. With a calm demeanour, he stepped forward, "Almost killed you back there. You looked harmless, so-"

"H- harmless?!" The creature was taken aback by his revolting statement, "You looking down on me or something?!"

"Yes, I'm in fact, looking down on you. Have you even considered the astronomical difference in our body stature?" He grinned.

"Oh, now I'm gonna kill you." It's brow twitched, "I'm gonna wipe that calm, smug ass smirk from your face, you repulsive, ego-inflated ape."

"Hmm.." Atomic Samurai's eyes observed the creature in front of him, "You look kind of familiar."

The monster's lips curled ever-so mischievously, "Do I?"

"Yeah. Something I've fought before, but you're definitely not it. Too small."

The monster's irk grew even more at that remark.

"Need me to jog all that memory up?" The creature's right arm began to enlarge, "Of course, it comes with a price. How's a massage parlor sounds?"

The creature leaped forward. With the intent to maul him, he swung his arm forward, but, as expected..

He slashed all of it's arms without exerting much effort into his movements, serenely tilting his head as he caught the sight of the arm vanishing into existence.

"I've faced creatures of your likeness countless times, and they met the same fate as any villains would. You are no different." Atomic Samurai serenely said, his confidence radiating like a vibrant rays of a raging star.

But then, footsteps could be heard from his rear side.

He caught the sight of an exact duplicate of the same creature towering above him in a rather bizarre position.

"So you're one of those types. The splitting types. Most infuriating, but I'll deal with you the same regardless." Atomic Samurai said.

"You're an actual idiot." The creature said, "I have many cells stored inside of me, anyone would've mistaken the numeral as infinite."

"So what? I could just shower you with the same amount of slashes." Atomic Samurai countered, as he formed the blade out of his air, it's blinding flame blazing in the air.

He yanked himself to the side, using the wall to propel himself towards the seemingly infinite amount of the duplicates.

"Ato-"

Three hundred were slayed.

"-mic!"

And plethora of others followed.

"SLASH!"

Wind whirled at the wake of his blade's slashes, as the multitudes began to disintegrate into ashes. In pride, the blade in his hands began to dissipate.

But to his dismay...

He could feel something staring from right behind him. That couldn't be right. It should've been dead! But the insidious aura emanating from his behind..

He couldn't be mistaken. He slowly tilted his head, anticipating the unruly horror that would devour him whole...

"Now you're fucked, Atomic Sandbag." The voice snarled, "You've gotten rusty, haven't you?"


...


"The heroes are here?" Asked a woman with a curvy figure, who wore a long white fur coat dangling above her shoulders.

"It seems so." Replied the big burly man, "We should step to the sidelines for now. There's a nearby exit on the left that we could use to return to the surface."

"Then proceed. We must leave here at all costs. Lest my sister finds us."

Her subordinates nodded in unison, as they walked to the designated location, supposedly the location of the exit...

But against their expectations, there was nothing there. Just a pile of rubble toppling the ground, rendering the exit inaccessible.

"Ah." Fubuki tilted her head to the muscular, raven-haired man, "Mountain Ape, any other exits that we could use?"

"... I'm afraid that was the only one that we know of."

"Then use the navigation device, dammit!" Fubuki pushed, her patience stretching thin.

"R- right!" He frantically picked the navigation device from his pockets, only for it to-

"Fubuki-sama, the device is jammed!"

"What?! What do you mean it's jammed?!"

"Wait, you guys got lost too?"

Fubuki and her subordinates tentatively turned their heads to the source of that voice.

The description of the man is rather plain. He wore a hoodie with a color scheme of red and white, with the word 'Oppai' transcribed in the middle of his chest. But most of all, his prominent is feature is the protruding golden hair extending to two different directions.

"And you are...?"

"Oh, me. I'm just a guy who's a hero-..." He halted for a while, before continuing, "Yagi. Yagi Toshinori."

"Yagi- no, wait, y- you're him?" Fubuki stumbled on her words, not believing what the man just uttered from his mouth.

"Didn't expect to see the biggest fraud in history wandering around in a narrow, empty space which conveniently happened to be the area where you guys are conducting your operations at the same time?" Yagi shrugged, "Me neither."

"No! That's not it! You don't notice me?!"

"What, a woman with a hate boner?" Yagi asked with a flat tone, "Save your hatred for later. I got a lot on my plate, so if you'll excuse me-"

"I'm Fubuki! Senritsu Fubuki! Tatsumaki's sister!" Fubuki dropped the revelation without a single hesitation.

That seemed to struck something inside of Yagi. His eyes narrowed, carefully scanning the woman in front of him.

He could sense the familiarity. Ah...

"No idea who you are."

"WHAT?!"

"Even if I did, I wouldn't waste my time running my mouth. I got something to chase after." Yagi said, taking the first turn to move his feet forward, walking past them.

He...he didn't even took the time to... Fubuki decided to drop it. A lot has changed ever since that day thirty years ago.

W- who the hell does he think he is?! Mountain Ape suppressed the cracking shell of his explosive emotions at the sight of this insolent low ranker.

"Oi, you don't get to treat us like a piece of decoration. Greet Fubuki-sama properly!" Mountain Ape demanded.

"Leave it." Fubuki lifted her hand, "Let's take his lead. He might have a way out."

"V- very well."

"You oughta be more perceptive, Fubuki." Yagi cut her short, "I got lost as well. The thing I could've used as a navigating platform of some sort isn't functioning properly, so I might as well use my intuition."

"Intuition?" Fubuki uttered the word, incredulous, "What were you doing in here, anyway?"

"Heard about the riffraff caused by the Monster Association. They were causing noises all over the cities so... I'm here to chastise them like a polite neighbor would." Yagi explained, though...

Fubuki knew it wasn't the full truth.

"You weren't listed at all in the operation." Fubuki blurted.

"Do I need to be? Heroes don't rely on lousy protocols to take action." Yagi countered. Fubuki couldn't repel that statement.

Yes. This is very much awkward. This whole conversation. She didn't even know if she could call it a conversation.

"STOP RIGHT THERE!"

"Huh, what's that vibration?" Yagi asked, rubbing his head, "Some kinda sound amplifier device?"

"Looks like we got caught under their territory.." Fubuki remarked, her wary expression sprung to life, "I didn't think it would come to this.."

"If you didn't wanna get caught, why were you here in the first place?" Yagi raised his brow.

But before Fubuki could respond, the voice blasted again, "I, as the member of the Monster Association, demands you to promptly exit the base to avoid any violent confrontation."

"Violent confront- Aren't you the one being violent?" Yagi raised his brow, "You kidnapped Garou, after all."

...that could be why he is here. Fubuki thought.

"I have no knowledge of the aforementioned person."

"Nevermind that. But then, even if we wanted to leave, we have no proper directions." Yagi explained, "We could use some help, if you want."

Fubuki's brows perked. Now this whole thing could turn out to have it's own merits. They needed to get out of there, anyway.

"...ah? Oh! Very well! There's an exit nearby to the left. Walk your way all the way to a dead end. You could find a lid covering the hole leading to the surface.

Yagi gestured for Fubuki and her underlings to walk to the left as instructed. Fubuki felt compelled to ask, "Are you coming?"

Yagi only gave her a wink, and waved her away.

Fubuki blinked at him for a moment, before deciding to leave him into it. She knew better than mostly anyone else that Yagi could handle himself.

...

...

"Aren't you going along with the-"

Yagi turned over to the right, a devious smile crept on his lips, "Guess I'll take the right."

"W- w- wait, hold on, what-?"

Yagi didn't bother to listen as he nonchalantly sprinted to the right, a victorious, mischievous grin plastered on his lips.

"Wait! D- Don't! I- I'm sorry, it was my bad, I shouldn't have done that! Oh my god, Nyan's going to murder me shitless...FUCK!"

His feet never stopped mobilising, and when he reached a dead end..

He was staring at the sight of a tall doorway that could potentially lead to a lair of some sorts..Better than nothing, right?

He jumped right ahead, and hulled straight through the solid concrete with his fists alone.

When he landed...

He could see a large monitor screen that acts as a surveillance system for this rather outlandish place.

Why would they need to supervise an area that is out of their residue's reach, anyway?

Oh right, to watch for any potential trespassers.

And the fact that the one monitoring the whole thing..

Was a human-sized cat with an attire of a goddamn vampire, makes this supposed fearsome boyband of monsters a little less credible. The fuck is this Monster Association anyway? Full of lunatics who can't even choose their employees right, if that's what they're even called.

"So," Yagi started with a slight curled lip, "Want a treat?"

"Y...you dare..." The feline monster stepped forward, it's teeth gnashing, it's vein bulging outwardly from his forehead, "You dare barge into my lair and degrade me into nothing more than a troublesome pet?!"

"You're a cat though." Yagi deadpanned, "Otherwise, what's with the whiskers? And the pointy ears? I can see that you have enough intelligence to get yourself some clothes, but a cat is a cat nonetheless."

The apparent 'cat' kept it's mouth silent, but in the inside, he was about to erupt like a car lit with a fire-inducing fuel.

"Anyways, you got any concealed information regarding the pathways to your supposed grand hideout?" Yagi went straight to the point, "Or perhaps you could point me into the nearest shortcut so I don't have to endure through the hassle of having to walk for another couple of hours."

"Insolent human, an information like that isn't easily as exploitable as you think they are, especially not with your insufferable attitude." The cat monster stood from it's chair, rubbing it's claws against each other like one would to a pair of blades, "I was hoping something would stir up, and you happened to be caught within my spider webs. I'll have some fun with you...maybe even more after I reduce you into nothing more than a worthless carcass. I'll even invite one of my peers. You'll love him. His name is Fuhrer-"

"Okay, okay, enough," Yagi held his hands up, "I came here for intel, not for you to go around spewing vacant threats."

As if that last part wasn't creepy enough.

"But knowing the place that you're in, I can't be inclined to believe that you don't even have a speck of information."

"I don't have anything to give you, OTHER THAN TO DELIVER YOU YOUR IMMINENT DEMISE!" The monster cat lunged forward, it's claws sprung forward, aiming to slit Yagi's throat.

But when it tried..

It's claws shattered at the slightest contact. Startled and desperate, it attempted to do the same with it's other arms, only for Yagi to catch his attack with a single finger, holding the claws back from making another contact with his neck, "Cut it off, otherwise you wouldn't be having any claws to play around with anytime soon."

"Y- you...how...what the hell-?"

Yagi twisted the monster's arms slowly to inflict pain, "I have to admit, your demeanour scares me a bit. Not because it threatens me, but because of what it would potentially do to any innocent bystanders that you stumble across."

"W- wha-?"

"I'm conflicted whether I should just let you go or end it for you. Of course, there's the information that you withheld, but then, there's also the aftermath of the whole exchange." Yagi said as he leaned forward, coercing the monster to take a step back.

That's when it dawned on it.

"W- wait... you're..."

No. He shouldn't be fucking here!

"You're A- A- All-Might?!" It spew, it's entire body trembling at the mention of the name alone.

"Does it matter?" Yagi asked, his tone gradually lowers as a mist began to shroud the view of his eyes.

"I'll tell you, I'll tell you! Please, just let me go."

Yagi's intense expression persists for a little while, before it abruptly morphed into it's usual state, "Cool. So you do have information."

"J- Just look for any...any minecart, there's a lot of those. Our base is located deep within the earth." Nyan replied.

"Where do I find the nearest one?"

"I- I can show y-"

"Nah, I didn't say you can tag along. After all, the outcome from all of this is still undecided." Yagi said, instilling the fear of uncertainty into the monster.

"There's one near my office, you go straight until you see a crossroad, and you should turn left from there on. You have to cross a narrow road with a bottomless chasm at the left, before eventually reaching the other side. There, you will find a minecart."

"Hm. Minecarts." Yagi rubbed his nose, "For a massive organisation, you sure have quite the primitive means of transportation."

The monster didn't reply to that.

"Kay then, guess I'll be going." Yagi turned away.

"W- wait, you aren't going to kill me?!"

"Nah." Yagi slowly tilted his head as he said that, "You didn't hear? The pro-heroes are already here raiding your shithole as we speak. One of them is bound to arrest you at some point so, no need to bother."

"They're her-?" It was interrupted when the alarm on it's room sounded. It looked back, only to see that some of the footage's shown in the surveillance screen..

Is replaced with a blank screen.

It turned it's gaze back to the front door, only to see that Yagi is already gone from it's sight.


...


Bang walked slowly, careful enough not to alert the guards there. With the passcode on his hand, he'd be sure to able to enter that ominous door he saw near the basement.

He was lucky enough that no one caught him in his endeavours while he's sneaking his way to the backroom.

When he finally reached the other end, he shifted his body to the side, tilting his head to his right, making sure that no one was on his tail without his knowledge.

The lane was clear, devoid of any living beings. He leaned forward to enter the passcode for the door. Pressing enter...

The door slowly creaked, mobilising itself by it's own without outside help, revealing the mist of darkness down below. Bang walked at a much more slower pace than the average, careful enough not to make even the slightest footstep noise with each step.

When he reached the bottom, the door behind him closed by itself, as if it already knew of possible trespassers.

Damn.

He turned his gaze back to the front. He could notice the elongated cleavage on the solid floor extending from one side to the other, as if the inhabitants of this very place didn't even bother to tend to it. Knowing their very nature, he wouldn't put it past them for being so unorganised. It's appalling to him all the same, though.

Not that it matters. His only focus is Garou. As he took his first step on the main grounds, which, some area's were soaked in a puddle of water.

He barely could see anything, as the torch provided at each side of the walls weren't vibrant enough to provide at least a decent view of what lies ahead.

That's when he felt a hand grasping his shoulder, "Hey."

Bang quickly turned over and attempted to attack whatever touched him at that very moment.

But he was very mistaken. It wasn't a foe.

"Look, I get what I did was unethical, but at least greet me like a decent guy would." The woman in front of him said, crossing her arms.

"Nana." Bang said, "And a friend." His eyes landed on the ashen haired man behind her, wearing an outfit that reminisces Nana's own, "Torino Sorahiko, was it?"

"That's me."

"Why are you two here?" Bang asked.

"To help you out, duh. I know what you and Toshi's been up to. Let's just say that I'm very proficient when it comes to spying on a person of interest." Nana replied, to which Bang wasn't pleased with. Spying is very unethical, for one.

"And since the Commission didn't even fill me in about the situation, I decided to venture out here on my own."

"They have no knowledge that Garou is being held hostage in here." Bang said with edge on his voice.

"Even if they did, they wouldn't so much as lift a single finger." Nana replied, "Look, I wanna help Garou as much as you do. It'd be a shame if he were to undergo a process that would render him beyond repair."

"..Your insistence are most appreciated." Bang said with his lips curled delightfully, as he walked away from them, "Yagi is on his way to the main entrance of the base. If I were a betting man, I'd say that he's already there, waiting for us."

"No kidding, did you hear about the 'mysterious tectonic shift' that happened a few minutes prior?" Nana asked.

"Yeah, though I doubt that was the case..." Bang looked at the ground as he walked alongside the, "Something must've happened."

"I'm of the same sentiment. This seems like something that he is capable of causing." Torino added.

"The casualties he caused are nothing to be scoffed at, though.." Bang shook his head, "I'll be sure to reprimand him about it."

"Kid's been through a lot," Nana stated, "probably just me, but I think his empathetic receptors have been...dulled significantly over the past few years."

"I know." Bang acknowledged, "There's no going back to the past, but he has to change soon if his rankings are to be moved to the top."

"You're still adamant about that, huh?" Nana questioned.

"Mhm, and as it seems, we have made an astonishing progress." Bang exclaimed, "And I'll see to it that he completes the process of reverting himself back to his usual, better self, maybe even more than that."

Before they could converse even further, Bang abruptly halted in his tracks, holding his hand up, "Wait."

"What?" Both Nana and Sorahiko questioned.

"You don't suppose there might be a booby trap laying somewhere around here?" Bang said, sceptical.

"B- Booby traps? Come on, it's not like they would go to such lengths. Besides, this is a road that they regularly take-" Nana was cut off short when she heard a clang of metal from behind them.

As they turned their head backwards, they could see..

The barrel of multiple railguns aimed at them, accompanied by a robotic voice from above, "Unidentified personnel have been detected. Identification bracelets are required for scanning and confirmation. Failure to comply will result in imminent death, regardless of your position."

...

Oh.

They're absolutely fucked.

TO BE CONTINUED!
