"Seriously, now I have to find another hat again..."

"""A-Ah..."""

Shredding his bucket hat in the process his face is then revealed; an unusual head design that looked like a firearm placed on top of a metallic mouth, or more accurately speaking a sawed-off shotgun that had a serrated toothed jaw attachment below it as his head. Having no facial humanoid features such as eyes or ears it's hard to tell how can he see or hear things, much even less to show facial emotions. Upon seeing this most of the G&K human personnel and T-Dolls had varying reactions, from amazement to intrigued comments.

"A full-body Extended, no, not just that..." One of the G&K personnel unconsciously uttered out loud as he looked at the one-armed giant's overall physique, "...A weaponized war-era model type, an Over-Extended..."

"Whoah... His face is a gun!?"

"What a funny face..."

"Shh, don't say that..."

"How the heck can he see things without eyes?"

"Maybe his optics is inside the muzzle, and then he shoots eyeballs, or something like that..."

"The hell are you saying, you Otaku Weaboo..."

"Don't call me that...!"

"A Gun Slave Unit!?" Berezovich Kryuger, G&K's founder and top officer, further identified the one-armed giant's classification, "From that infamous Combat Unit!?"

"...Gun Slave Unit?" Looking at his superior incredulously the G&K Commander had a puzzled expression as he had never heard of the term before, "What is that?"

"GSUs are the product of Big Ships, Big Guns Doctrine created during WWIII, and among the war-model type Extendeds they were the most successful combat units deployed at that time period." Kryuger briefly explains this to the G&K Commander, "Each one of them is said to be powerful enough to take out an entire nation's army on their own so they are usually sent into the frontlines with very little or no support from regular military units. Barely anyone knew about them as they were all decommissioned right after the war ended so never I have imagined I'd be seeing one myself in this day and age."

Looking at the G&K Commander, that made the military officer tensed up a little as it was like he was aiming his gun-head at him, "I'll be showing off for a bit, but please remember our deal..." the one-armed Over-extended then shifted his focus on the little girl with his index finger pointing at her, "And you stay put with them until I say it's safe. We don't want to go through that hostage play again..."

"B-Big Bro..."

Taking away its shield and grabbing the disabled Aegis-GA at its leg the one-armed Over-Extended throws it outside as a taunt at the enemy units outside the building, in which the KCCO infantries respond by momentarily halting their gun fire and taking defensive postures on the streets.

"Looks like they get my message. Let's do this, then..."

"H-Hey, what is he-"

The Over-Extended then waltz out of the apartment casually, equipping the looted shield on his hand. When he made it outside the building he was met with an entire division of KCCO units, composed of varying designs of Cyclops, unmanned light tanks, human foot soldiers and a pair of gigantic heavily armored dolls armed with hi-powered weaponry. While standing there he observes their formation for a moment before crouching and puts the shield in front of him.

"Hmph, back then they've send many Over-Extendeds to fight wars due to the Limitation of Drone Weaponry Treaty... but now people would make armies of these things and banned us from being seen on the battlefield... how laughable..."

Readying their fire arms the KCCO units take aim at the sole enemy unit who took stance in front of them that raises the looted Aegis-GA's shield as cover, and let their guns spit lead against it. Meanwhile the one-armed Over-Extended plants the shield's lower section to the ground and readies his arm in a retracted position.

"Wait, that stance..." One of the G&K human personnel then notices the one-armed's movements and at that time he realizes what's the Over-Extended's next step he warns his comrades with, "Everyone, cover your ears!"

"""Huh!?"""

"Just do it!"

"Schall Faust!"

A piston-like device can be seen on his left fist cocks in and slides, and then the Over-Extended punches the shield with much brute force that it creates a pseudo-sonic boom as the defensive equipment flies over towards the KCCO vanguard squad with the resulting shockwaves rattle the human infantry's ears despite wearing noise-cancelling equipment. The mechanical units were also affected as well, having their sensitive sensors severely damaged and internal electronic systems partially broken, and one of the Minotaurs knocked down after being hit by the flying shield.

"Aaagh, my ears! What in the world was that!?"

"Wh-What the hell did he just do!?"

"...GHaaghh! I almost blacked out from that!"

"Urgh... Mama..."

The G&K T-Dolls and human personnel that were hiding inside the apartment weren't spared from the pseudo-sonic boom's effects, with some of them weakened from the sudden outburst or outright knocked out cold after the impact.

"Time to do some direct damage...!"

Using the chance that they're still disoriented the Over-Extended dashes toward the KCCO human infantry units and armored T-Dolls he then takes them out with swift hand-to-hand combat tactics. One of the human soldiers attempts to gun him down with a rifle, only to be evaded in a swift gliding motion and ended up being punched in the gut. A Cyclops SG also does the same but it also failed, having its chest kicked away before the infantry doll can fire its shotgun. An Aegis-GA successfully lands a hit on his back and tries to electrocute him with a shock baton, but it only made the Over-Extended to take his attention, grabs it by the arm-holding weapon and literally uses the armored doll as a makeshift bludgeoning weapon until it breaks up into scraps. After taking out most of the still combat capable units in this process...

"Well, this will hurt a little. Bear with me."

Grabbing another Aegis GA with its shock baton active at its left arm the Over-Extended then throws the infantry doll to a Typhon, further damaging the unmanned tank and disabling it to move around. A KCCO human soldier attempts to throw a grenade at the one-armed Over-Extended, only for him to catch the hand explosive in mid-air and rebounds it to a Coeus tank that severely damages the hovering weaponized platform.

"That's it for the tanks. Moving on to the infantry units..."

Looting a disoriented KCCO human soldier of his grenades the Over-Extended uses it to blow up several formations of Cyclops and human soldiers that began to regroup, which he repeats the process with another grenade-carrying human soldier until most of them were reduced to messy combinations of dead bodies and broken mechanical parts. Since there are Archers mixed into their formation they are also caught in the random grenade blasts, igniting their equipment and incinerating everything in their perimeter.

"The fire should be able to take care of the rest. Now all that's left is..."

He then proceeds to rush towards the attacking Minotaur, dodging its missiles and lasers with fluid strides and his fist's piston mechanism cocks into position. When he gets into an ideal range he then throws his punch at the intact armored doll, which is then met by an energy shield. Curiously, even though his skin has been burned up by the energy shield's effect he managed to get his punch through it and hits the Minotaur's thick armor. When his fist make contact with the armored doll's torso he shouts-

"Schall Faust!"

A huge concussive blast was released from the Over-Extended's fist, causing the Minotaur's heavy armor to warp on the targeted area and its internal mechanisms to erupt into small explosive bursts and flames that engulfs the large armored doll until it finally shuts down. When he's done his hand ejects something like an empty bullet cartridge that pops out from the wrist, by which he 'reloads' it by picking up another cartridge from his pocket and slides it in on his wrist slot, all done using the same hand.

Looking at his burned up hand, "Tch, And they all said to me that this specially insulated synthetic skin of mine would be durable enough to withstand any energy-based weaponry..."

Walking towards the other Minotaur that got hit by the shield earlier he then preps up his fist again by using his chin to slide up the piston. When he's now beside it he finishes off the still struggling heavy armored doll with the same attack targeting its central section, denting its armor and causing sparks and fires jumping out of its frame until it powers down. With some of the G&K members recovering from the aftershock bear witness of this development voiced out their varying reactions.

"Is it over? What happened..."

"There's fire all over the streets, and the whole KCCO forces were wiped out... Don't tell me he did all of that on his own..."

"How in the... Those Minotaurs can generate an energy shield that almost negated our bullets, and he defeated them with a single punch..."

"The way he attack those KCCO infantry is outright reckless and crazy, but without a doubt he's experienced in fighting..."

"Quick, powerful, and can tank an electric shock of that level... and he only had a single arm to work on taking out an entire division..."

"...He's not some kind of a new model of Tactical doll, right?"

"That's an Extended, didn't you hear?"

"Whatever he is, he's not your average old man, that's for sure..."

As he finished taking down the pair of KCCO Minotaurs another KCCO machine came jumping out of nowhere and landed just behind him, with sensors focused on his figure and identifies him as an enemy unit. The olive green machine had four legs that made it look like a spider tank armed with machine guns and large cannons.

"You've gotta be kidding me... a Hydra!?" One of the G&K personnel shrieked in fear and shouts as he saw the KCCO armored drone readies its weaponry and aims them at the one-armed Extended, "You've got no chance against it, run away now!"

"Dammit, we don't have enough ammo against that thing right now...!"

"So you're the hidden boss, huh..." Prepping once again his fist's piston mechanism using his chin the one-armed Over-Extended makes a stance that seems he's going to run head-on towards the new threat.

The quadruple-legged machine begins its attack at its target with alternating intervals of its machineguns and cannon fire, giving no chance to get close against it and forces the one-armed Over-Extended to do swift side-steps and sudden dashes in evading the deadly rounds.

"Khh... Dammit!"

Though using his surprisingly hi-level of reflexes and agility to avoid being hit the one-armed Over-Extended still suffered some minor injuries on his chest, shoulders and legs due to some hot leads grazing him from close-call fatal shots. During this time, a pair of sniper rifle bullets hit one of the machine gun installations of the Hydra, momentarily taking off its attention from its initial target and stalls in movement to trace out other hostiles.

"..Hmmph!"

As the green machine was distracted from a sniper rifle round the one-armed Extended manages to get close to its main body and does a left straight at the side. Even with its nigh-impregnable armor the Hydra can be seen malfunctioning after being hit by his punch, shaking and slowing down on its movements. Now that his fist has clashed on the Hydra's armor...

"Schall Faust!"

With this attack, he creates a massive dent on the Hydra's armor and starts a chain reaction of explosions on its internal mechanisms that lead to its self-destruction. When he looked at the direction where the bullet originated from he can see Springfield and WA2000 at the apartment's top floor, with the former waving at him to congratulate his victory.

"Thank you for your hard work~"

"You're pushing yourself too hard, old man."

Several other G&K personnel who also witness his feat made side comments on the Over-Extended's capabilities and strengths.

"No way... he took out that thing with a single punch!?"

"Okay, that was so badass..."

"And very ear-tearingly loud..."

"So this is the power of a weaponized Extended, the Gun Slave Unit..." The G&K Commander, upon witnessing the destruction of the KCCO forces, makes a keen stare at the one-armed Over-Extended with a high sense of danger, "I'm glad that he offered to help us, though I never want to imagine how much he can do at his prime..."

"Everything's burning..."

"...There's no more enemies, right?"

As they observed that there are no other visible hostiles active in the area, the G&K PMC group decides to leave the apartment and investigate the remains of KCCO forces, checking for any survivors or salvageable goods with them. In doing so they also approached the one-armed Over-Extended with great caution, since he destroyed their opponent in behalf of them but still unsure whether he's a threat or not.

As if he knew what was on their minds the one-armed Over-Extended said, "Don't worry, I'm your ally here. Though, I would like all of you here to be silent about my existence, since I'm a renegade Over-Extended that's been running around for years." he then draws out a syringe from his pocket and injects himself with it on his neck area, "And also, please keep that little girl safe while we escape this town. That's all I ask for a compensation for giving you guys a helping hand..."

"""...""" The G&K human personnel and T-Dolls then looked at each other first and nods in unison twice, all agreeing on accepting his terms.

"He and I had a deal about this just now." the one-armed Extended then points his finger at one of them, "Just ask him for more details."

"""...""" Everyone then directed their gazes at the man whom the one-armed Extended was pointing at, and is quite a surprise for the G&K to find out who's the one he's referring to.

"I'll explain later." Raising his hand to spare him from the torrent of questions and sharp gazes the G&K Commander interjected with, "For now let's get going. There's going to be more enemies coming if we stay here any longer, right?"

""""..."""" An awkward silence can be observed while most of the PMC members stares blankly at the G&K commander, as they never thought that he would go make a deal to a stranger without telling them beforehand. Nevertheless, they knew it's a critical situation right now so he must've done this for their survival and they all decided to put the issue aside and prepares to move out. However, as they're still packing things up...

"I-Incoming hostiles!" Holding a digital pad FN-49 alerted everyone with a panicking voice, "ETA in 3, 2 ,1..."

"Dammit, looks like that we're a bit too late for that..." The G&K Commander then grits his teeth in frustration and later he shouts his command with, "Everyone, combat formation Delta!"

""Khh...!"" Looking for covers and vantage points the T-Dolls readies for another round of gunfight as they anticipate the approaching hostiles.

"...!"

Another enemy formation arrives into the scene, but this time they are themed in white painted armor and armed with highly advanced energy-based weaponry. Some of them had their combat gear in perfect condition, while others had slight damages, missing parts and fluid leaks in cracked armor sections.

"Tch, this time it's Paradeus, huh?" The G&K Commander clicked his tongue as he prepares his service firearm while taking cover on a nearby collapsed building debris.

Halting their salvage operation the G&K T-Dolls who first arrived on the fiery scene forms a pair of combat echelons to respond against the hostile Paradeus units, taking cover on any obstacles and debris they can find that was created from the earlier exploits of the One-armed Over-Extended. The rest who still remained on the apartment provides covering fire for the two vanguard Echelons.

Prepping his hand-mounted weapon again with his chin, "Tch, looks like things won't simmer down as peacefully as I want it to be...hm?"

Shooting down a few Strelets as she approaches them, "Let me provide you with covering fire." A seemingly generous UMP 45 offers her assistance to the Over-Extended with a narrow-eyed friendly smile, "With only a single arm to work on it'll be quite difficult for you to handle these guys, so I'll be your guard on the left side."

Taking down several other Strelet plus in the same manner, "Count me in as your back-up, too~" Another T-Doll who slightly resembles her, UMP 9, also presents herself to aide him, "Me and 45-nee will provide excellent covering fire for you."

"Uhh, thanks..." Though not visible the Over-Extended had a confused facial expression as he 'stares' at his two new allies, "...What's with these two?"

With shields active the Roarer charges towards the G&K Echelons in a rampaging fit of deadly rush attack, with its humongous arm raised in a stance of downward smashing fashion. When the enemy white mechanical giant unleashes a seemingly electrically charged punch the one-armed Over-Extended steps forward and counters with his own heavy left straight, aiming at its fist's center.

"Hmph!"

The towering Paradeus white mech's attack was cancelled and creates a weak shock wave as it clashes with the Over-Extended's own fist, astonishing both the Roarer and the two T-Dolls behind him. With his fist slides down towards the Roarer's chest he then shouts-

"Here, I'll help you get back to your own team! Schall Faust!"

With this attack it made the white giant flew back towards a squad of Strelets, crushing several of them by its own weight. Despite this however though the remaining Paradeus units keep advancing to their position and attacking G&K forces without a pause.

"Tch, we don't have enough ammo to take on these guys right now...!" A very annoyed Skorpion snarls at the fact that her bullets couldn't punch through the energy barriers of Thunders, not to mention that there are Rodeleros and Doppelsoldners fast approaching behind a Strelet squadron as enemy reinforcements.

With the Paradeus units slowly getting the upper hand in the ongoing battle the G&K Echelons began to feel disheartened as they're slowly being surrounded from every directions and outgunned in almost every way possible.

"Enemy reinforcements approaching at twelve!"

"Dammit, at this rate we'll be surrounded by these bastards...!"

"If only... If only we have something like a one-hit attack that can break through their barriers..."

As If being in cue, "...There's only one way to take out all of them at once, and that lies on my plan." The Over-extended answered their growing concerns in a tone implying it's the only option they have.

"""...Huh!? What plan!?"""

"It's simple." The one-armed giant then turns his head towards the G&K echelon, "I'll have someone accompany me to lure all of them in front of me, and then I'll unleash a one-hit attack to wipe them all out."

"...Wait, what?" The G&K Commander had an undrawable expression in his face upon hearing the Over-Extended's suggestion, "How does that work!?"

"You guys wanna get out of this situation alive or not? Now's the time to decide for that." The Over-Extended's tone of voice becomes a bit deeper when he asks that question, "We don't have much time... So, who's going with me?"

With his proposed plan sounds to be an outright ridiculous and dangerous move the G&K echelon units had their faces molded in doubtful expressions, trying to process what he just suggested as a solution to their current problem. However, given the situation and little time they have to respond the G&K combat personnel decides to trust his plan and approves this risky move, but the question remains as to who will accompany the Over-Extended for this certain plan to work. The Over-Extended silently awaits for their answer as to who will be joining him as decoy, but no one seems to be willing to take the role, until...

"...Fine! I'm the one who made a deal with you anyway, so I'll go along with your plan!" The G&K Commander then steps forward the Over-Extended and makes an exasperated expression as he asks, "So, how do we do this?"

In that moment the only response the Over-Extended gave to him was, "Follow me."

Getting out of their cover and moving forward as vanguard the one-armed Over-Extended with the G&K Commander in tow run towards a central intersection to taunt the attacking Paradeus units and lure them to a certain location that can be considered as the street's choke point, and then they stand still there in front of the rampaging Roarers, Doppesoldners, Thunders and Strelets. Meanwhile both UMP sisters and several other T-Dolls were harassing the heavily armed Paradeus Dolls to distract them from directly attacking their commander and the Over-Extended until they reached their target location.

"Alright, what's next?" The G&K Commander nervously asks, as he had never experienced fighting Paradeus units head-on armed only with a service pistol and a weird stranger as his companion.

"On my signal, pull the trigger on my head." The Over-Extended glances at the G&K Commander before he kneels with one leg so that he can reach out to the trigger-like device on his head, "We only had one chance, so don't miss your timing..."

"...Huh?" Confused the G&K Commander had a raised eyebrow while glaring at the Over Extended as he had no idea what are they going to do.

"Ready your hand to the trigger in my head. Now." The Over-Extended instructs the G&K Commander with an urging tone, with his focus pointed directly at the incoming Paradeus forces, "We're in a 60/40 situation right now."

"A-Alright...!" The G&K Commander replied nervously as he reaches out to the Over-Extended's head trigger.

With majority of Paradeus forces coming in hot towards them the G&K Commander had only seconds to react and decide their fates, and that last line the Over-Extended said to him further complicates his current mindset. Witnessing the leading Roarer raising its fist to deliver a lethal smashing blow followed by Rodeleros and Thunder units rushing toward the pair, the G&K Commander brushes off any hesitations in his mind, steadies his nerves as he grabs firmly the Over-Extended's head trigger and awaits for further instructions. In a short moment the Over-Extended shouts his signal saying-

"Pull the trigger now!"

At that timing they were already at an ideal distance the G&K Commander immediately pulls the trigger of the Gun-headed Over-Extended, causing a surge of multiple strings of pure energy that comes out of his (Face)muzzle. These scattering beam blasts penetrates through their barriers and melted the armors of Paradeus units, seemingly like ice being exposed to hot iron rods that reduces all of them to molten material. The resulting attack is so strong that it takes out not only every Paradeus units that's in front of them but also reduces the surrounding area into mere rubble and debris.

"...!?" The G&K Commander staggered a little on his foot as he didn't expect how powerful the Over-Extended's trump card against the Paradeus Units.

"""...!""" With the annihilation of their main forces some of the Paradeus units had lost some of their morale and command structure, allowing the G&K group to finish off the remaining enemy stragglers and eliminate all hostile units within the area.

Looking at the direction where did that massive blast came from one of the G&k personnel had a meme-worthy astonished expression as he looks at the Over-Extended's head muzzle emitting smoke with G&K Commander standing beside him in front of carcasses of destroyed/melted Strelets, Rodeleros, Doppelsoldners, Roarers and Thunders, "Holy smokes, did that gun-headed guy do all of that!?"

"Huh... I've never thought that I've let someone else pull my trigger... again..." Recovering from the devastating attack he made the Over-Extended splits his head in the middle much like any typical sawed-off shotgun ejecting a pair of empty shells and cleans up the residual burns using only his left hand. This made the G&K Commander flinch a little, as he had never encountered a cyborg who had a functional firearm for a head and manually handles it like an old-fashioned weapon.

"So you can't fire that gun head of yours by yourself?" The G&K Commander asks the Over-Extended with a steady stare, wondering as to why did he have to accompany him and be the one to pull the trigger on his head.

"Long story short, I'm part of a two-man cell team during the war. And my partner acts both as my handler and safety trigger, so most of my body's special functions can only be activated to his discretion... And I've only allowed a few people other than my partner on using my powers...", The One-armed Giant replies with an implication that he's actually quite reserved from letting anyone show his capabilities and then continued with, "By the way, I heard your detachment group is on the town's southwest area, right?"

"...What about it?" The G&K Commander replied to him with another question, unsure as to why he would ask something like that out of nowhere.

"Tell them to continue towards the southernmost boundary of this town, and we will rendezvous with them on a half-demolished automobile factory. They should be able to slip through enemy units on a narrow residential pathway maze just beside the town's western border." Handing over a hand-drawn map of the city to the G&K Commander the Over-Extended then continued to explain his escape plan, "Just beside that factory there's an abandoned motorpool over there with some functional Trucks and Humvees that I found while the two of us were scavenging for goods, and I think that we can use those to get our arses out from this town. And, since the nearby southern entrance is not an ideal location to enter and exit this town there should be few or no hostiles lurking in that area."

"...Okay, I guess it's the best option we have right now." After thinking thoroughly what the Over-Extended had said the G&K Commander agrees to his proposal but before he gave out his order he added, "Any other notable gimmicks you have that you might want to share to me in case of emergency?"

"..." Answering the question with a silent treatment the eyeless Over-Extended just 'aimed' his muzzle directly to the G&K officer's face, implying that those things shouldn't be disclosed haphazardly.

"...Right, sorry." The G&K Commander makes a subtle nod as an apology to the Over-Extended and later gives his order, "Everyone, salvage as many resources as you can in this area, and we'll later move out to the town's southern district, with this guy as our lead!" as he presents the Over-Extended beside him with a pat on the shoulder. He then later directs his gaze towards his blonde secretary and ordered, "And Kalina, contact the AR team to retreat and crawl into a nearby residential pathway and navigate their way into a car factory at the southern end, and we'll rendezvous with them at that location!"

"On it!"

"""Roger!"""

After packing up enough items looted from KCCO and Paradeus units the G&K PMC group prepares to move out and follows the leading Over-Extended as their guide. Though the little girl insisted on walking with her partner side by side she was later convinced by the Over-Extended and several other G&K personnel to stick with them for a while as they move out to give her a better protection in case of enemy encounter. While navigating through the maze of residential blocks the one-armed Over-Extended and several other vanguard T-Dolls quickly eliminated small enemy scout formations, as fast and efficient as possible preventing any larger enemy groups from detecting them.

"We're almost there, but stay vigil-no, nevermind..." Leading the way the One-armed Over-Extended remarked the T-Dolls beside her, however this seems to be unnecessary as the T-Dolls were pretty much on the edge with their weapons at ready aiming at every possible angle and taking turns on scanning the area.

Turning on the last corner they've finally arrived at the designated rendezvous location, with some of the T-Dolls doing a recon at the car factory's perimeter. With the motor-pool just a few walks away beside it with several vehicles parked and the town's southern gate just a little beyond a few blocks away it was an ideal escape route, but the path that connects it to the outside world is a very dangerous one; the road is a broken jagged terrain with several ponds of Collapse Fluid scattered in the vicinity, making it almost impossible for anything to pass through it.

"Damn, this isn't what I've expected to see..." The G&K Commander thought to himself as he stares disgustedly at the puddles of Collapse Fluid just in front of him, "Well, not the most ideal meeting place but looks like we don't have much of a choice but to wait here for the AR Team to-"

*BLAAMM!*

A blast of plasma then destroys one of the Humvees that was nearest to them, setting it ablaze and alerting every single T-Dolls and armed G&K personnel in the vicinity, weapons at ready to engage to whoever fired that powerful attack. The enemy's location is still unknown until someone spoke in a certain voice they would recognize.

"Hmph, it seems like I have to do some thorough house-cleaning, after all..."

"""Ah!?"""

Redirecting their gazes at the source of the attack the G&K group then saw three silhouettes of female figures haughtily walking towards them. The G&K members immediately recognize the voice and silhouette of the three attackers who shows up from the shadows, especially the leading one that dresses up as a Gothic maid.

"Damn it all... It's Agent!"
