Master of arms.

Chapter 1: Realization

A/n: Okay here's a deal. I'm not gonna write a draw out opening for this stories. If you want to know what happened then it's basically the same how the first two to three chapter of [insert writer]'s From Fake Dreams and I'm going to explain the needed details for you to understand. I ain't one for opening, so please do not be angered. I'm just not good enough to make a decent opening.

It's late at night with the stars already shining brightly tonight, finishing some of the last repairs. Shirou starts to wipe some of the dust and oil from his hands and cloths. While doing this he remembered how life has happened for the past few years for him.

It all happened with the fire in Fuyuki ten years ago, the fire that claimed the lives of at least five hundred people, with him being the only survivor. He did not come out unscathed, what happened in the fire had changed him, especially his mind. But luckily he was saved by a man named Kiritsugu Emiya. Right after rescuing him from the fire, the man had adopted him as his son. The next two years went by rather peacefully, until Kiritsugu revealed to him the existent of magic or the proper term is magecraft or thaumaturgy, after that he had practically begged the man to teach him. At first the progress was low and dangerous due to him not opening his circuits correctly but it was quickly resolved before anything bad happen. Even then his best spell is a heavily modified version of Projection he called Tracing and Reinforcement with the Emiya family magic Crest on Time Manipulation and Altering, although it is not to the point of being the Fifth True Magic.

Afterwards he discovered his {Element} and {Origin}. His {Origin} happens to be [Master of Arms] meaning anything related to a weapon or tools of massive destruction can be understand perfectly by him, his second {Origin} is shockingly [Severing] like his father which explains why the binding of the Emiya Magical Crest worked in the first place. After sometime, both Shirou and Kiritsugu chalked it up for Shirou to be part Emiya from a distant cousin. Shirou's {Element} is [Lightning], apparently he aslo have a staggering number of one hundred magic circuits with fine quality. With how rare and dangerous his {Origin} and {Element} is. He is sent to a few people his father knew who would help him at the Clock Tower, and for ten years he learn everything he can. How to use fire arms, CQC, runes and even alchemy.

But the most shocking discovery was the existence of a Reality Marble. His Reality Marble to be exact. It took him a few months to know how to activate it by himself and took him to last week just to understand its nature. His RM allowed him to learn, copy, familiarize and a fully synchronization any type of weapon and store them to his RM with the corresponding forms and katas hardwire to his being. Even martial arts style is not spared when he got an extensive exposure to it. But not without drawbacks too, even if his RM allowed him to synchronize any form of fighting style, he still have to train in it so not a total hax.

Shirou was cut off from his thoughts when he heard loud noise coming from the school ground but not just any sound. It was the sound he knew all too well.

It was the sound of metal hitting metal.

'Let's hope it's not what it is.' Shirou thought.

Rushing out to the field, he saw a breath taking scene. Shower of sparks and steel with whirlwind of compressed air twisting and turning like a hurricane incased with each strike. Looking closer with his reinforced eyes, Shirou saw a man in red with tan skin and white hair. In his hand are two beautiful crafted falchions, with a black one in his left and white in his right. The second man with blue hair was wearing some kind of blue spandex holding a red spear. However, to his surprise, Shirou saw one person he wouldn't expect.

Rin Tohsaka.

Her expression is one of total surprise and huge amount of fear. Seeing such inhuman feats, Shirou concluded his worse fear. The Holy Grail War has already started. Backing up out of surprise, he didn't notice the box that contain the repairing tools and spilled everything on the floor. Cursing his luck, he looked back at the field and saw everyone was looking at him. Scratching his head and smiling nervously, he said.

"Ahaha… Nothing to see here. Carry on!"

And then applying Reinforcement on his limbs, Shirou did everything a man would done in his situation. He ran like hell.

After a running in the school halls, he felt something was going to impale him from behind, Shirou quickly activate his Magic Crest and performed "Time Alter: Double Accel". Feeling that time seems to stop, he traced a pack of C4 and stick it to the spear that almost impaled him. Shirou then stop the spell and stand still letting the spear fly through him and to make sure. Using his [Mystic Eyes of Distortion], he twisted the air around the spear and changed its trajectory.

Not long after the owner of the spear appeared and catches his blood red spear, looking closer he saw the man seems to be European with his face structure but his eyes seems to be very unique with the color of crimson so deep they felt like blood with slit pupil. The man's smirk looks like he found something amusing.

"You're quite the nimble one, kid."

"Thanks. But I'm a busy person so I will excuse myself right now."

And Shirou proceed to dive out of the nearest window and continue run but not before shouting.

"Surprise! Mother fucker!" and pressed on the trigger on the detonator.

Blinking in surprise, the Irish man was going to give chase when he heard a beeping noise. Looking down to where the sound came from, he saw a white glob of clay at the shaft of his spear. By the time the Grail sent him the information on what the clay was actually an explosive, it had already been too late as the pack of C4 exploded. The force behind the pack of C4 was enough to collapse the foundation of the block Lancer was in.

"Fuck fuck fuck fuck! Fuucckkk!"

Running as fast as his reinforced legs can carry him, Shirou dashes to his house like a mad man to arm himself because he had no illusion he just killed a Servant with just a bloody pack of C4. Seeing the front gate of his house, taking a big leap, Shirou jumped through the walls of his estate. Quickly entering his home, Shirou turns on the motion sensor that was scattered across his property.

Once he checked through the whole security system. Shirou makes his way to the basement where he keeps all of his arms. Opening a drawer full of firearms, ranging from pistols to rifles, Shirou grabs his two most favorite handguns. The Maxim 9 with integrated suppresser, layered with levels upon levels of runes to strengthen the durability of the hand gun itself while also used Alchemy to lessen the weight on various parts and enhance the said part's performance. Smiling lovingly at the handguns, Shirou also grabs the holster and a bucket load of ammo with gems acting as the bullet. Now you may ask, why use gems for bullet points? They are no ordinary gems; each was filled with at least five years' worth of prana storage. Each element was filled within the corresponding color of the gems. Rubies for [Fire], Topazes for [Lightning], Lapis Lazulies for [Ice], Emeralds for [Wind], and the most expensive of all, Diamonds for the essence of his {Origin} of [Severing]. The diamond bullets act much like his father Origin Bullets that as made from his bones. Shirou do still keep some of them but they were not in the caliber that he usually use, as it was crafted for the Thomas Contender G-2 hand gun.

Finally, he strips off of most his clothes and dress in his combat outfit. The outfit in itself is a proper Mystic Code, abeilt an easy one to craft but one none the less. The attire consists of a white high collared shirt with ballistic resistant weave, wearing over the shirt is black body armor with silver lining and a black coat that reaches to his knees with Silicon Carbide plating. The outfit also has the holsters for his handguns and an overcoat, steel toe boots that reaches his knees with shin guards. Black cargo pants tighten by a leather belt with a silver buckle. The whole outfit has layers of reinforcing runes enough to take a hit from a speeding truck and still keep the wearer survive as long as his or her feet is planted firmly on the ground or any solid surface.

Also grabbing a few gems that has been collecting mana from the air under his house for later use, Shirou proceeds to the ground floor and rushes to his shed his instinct screamed at him to dodge and he vaulted forward, barely escaping the viscous swing that would have cleave his head from his shoulder.

Looking back, he saw it was the man that tried to impale him from earlier. Backpedaling, Shirou raises his pistols at the man in the blue suit and took a few shot at him. The man however, just swatted away his bullets like flies.

"Hoho! A feisty one eh?"

The man said, unnerving Shirou with how the man casually talked after having a pack of C4 explode at his face.

"Gonna hand it to you kid. You somehow DODGED my spear AND surprise me with that explosive. You have some luck on you kid."

Shirou snorted at the man claim.

"But…"

And that's the cue for Shirou to dodge. Already activated his circuits, Shirou prepare to charge his guns full of prana when he froze. The air seems to become thicker by the moment and bloodlust filled the atmosphere as the red spear in the man possession glows and the unholy energies exudes from the spear in waves. The Irish man crouches low before jumping high in the air reeling his arm back, the man shouted.

"Gae Bolg!"

"Time Alter: Triple Accel!"

Time stops in front of Shirou as he brought his handguns in a 'X' like pattern trying to redirect the spear that is about to pierce him. Once again forcing his Mystic Eyes to work in conjunction with his guns, Shirou managed to redirect the spear. Dropping the spell from his Magic Crest, the Noble Phantasm impaled the ground right under him and flung Shirou from the sheer force of impact. Taking this chance, Shirou charges his gun with lightning prana and take a shot at the Heroic Spirit.

Of course the Spirit managed to dodge his bullet but did get electrocuted, although minor but it's still a hit to Shirou.

Getting on his feet again, Shirou quickly cast a minor healing spell for his heart. This is the downside of the [Time Alter: Triple Accel], by multiplying the user's reaction speed and body function it causes a massive strain on the whole body, however given time and practice the strain can be lessen and the pain is nothing more than a sting on the body. Shirou's body already got used to the pain but not the heart, as it has to supply more blood to his body. The effect itself is not lethal, but the strain is still there. Feeling his heart beating steadier, Shirou once again stare at his attacker while thanking for the absent of the Irish man accomplice.

"So, what made you trying to kill me so hard?" Shirou asked.

"Sorry kid. Just trying to keep the secrets and all. But so far you're putting up quite the decent fight. For a normal human that is."

Snorting at the ''normal' part. Shirou was anything but normal, his {Origin} alone could earn him a Sealing Designation and all of his {Elements} and {Origin} is not one that is normal at all.

"At least before I die, could I get the name of the Hero before me so I can brag in hell?"

"Sure, kid. The name's Cú Chulainn, Hound of Ulster!" The now named Cú Chulainn spoke with pride in his name.

Reinforcing his whole body to the absolute limit. Shirou dashes at Cú Chulainn with the man doing the same. Cú swing his spear in a wide arc but Shirou dodge it by bending backwards and send a bullet from his left at the opposing man's head. Not wasting any time, Shirou swing his right pistol aiming for the man's temple but had to once again roll away to escape the returning swing from the spearman.

Leaping high up in the air, causing the spearman thrust to miss kicking up more dust, using the smoke screen Shirou charges his pistol with lightning and fires at the cloud of smoke.

"Raikiri!"

The lightning covered bullets tear through the smokes and gouges out the ground and leaving scorch marks. Holstering his left firearm, Shirou takes out a grey piece of gem and crushed it just in time for a magic shield to be projected and protect him from the brutal swing from the spear of Cú Chulainn while shattering in the process. The shield however did not protect him from the kinetic force behind the swing making him flying back and crashed to the wall causing spider web cracks on the wall itself.

Getting up quickly, Shirou realized just reinforcing his body is not going to help him anytime soon so he pour prana to the rune sequence that releases lightning to stimulate his nerves for enhanced reaction speed while also offer some added protection since it always has a layer of lightning acting as exhaust so he doesn't fries his body from inside out. He activated the cloak just in time to narrowly tilt his head away from the blade of the spear that almost pierce his head. Rushing to the Servant, Shirou unleashed an onslaught of punches and kicks with some bullets just for good measures. The Servant easily dodges most of the blows or blocks the ones he can't dodge.

Jumping back, Shirou throws a few Topazes at the Servant unleashing bolts of lightning at the man. Being unable to response to the raw lightning coming towards him, Cú Chulainn was forced to take the lightning head on. But with [Magic Resistant] being C, he didn't take the brunt of the spells and left pretty much unscathed.

"Oh come on!"

Shirou shouted in indignity at how the Servant treated his lightning like a breeze of wind. That is what probably insulted him the most. Bringing out another gem and crushes it, releases all of its content, Shirou uses the prana to conjure up multiple magic circle rapidly and chanted.

"Verfestigen, Schärfen, Durchdringen."

"Kavallerie-Schreck!"

Spears that was made from lightning formed from the magic circles, its long twisted blade made for piercing even the thickest of armor, and all of them was aimed at The Hound of Ulster. With a mental command, Shirou launches all of the spears at Lancer continuously.

Lancer wasted no time to dodge the barrage of lightning spears while blocking any spears that came too close. While Lancer is distracted with his spears, Shirou is busy thinking ways to hit the Heroic Spirit.

"One Verse spells is not enough. I need spells that has three or more Verse to even hurt him. Fuck! This is getting out of hand."

Seeing Lancer getting closer to him, Shirou panics and force more prana to the magic circles. Even with added fire power, the Hero keeps coming at him. With no other choice, Shirou stops the barrage and began to chant.

"No choice. Code Black it is."

"Born through Steel and tempered with Fire.

Born to be the Weapon but shackled by the Heavenly Chains.

But with my strength, I Sever my shackles.

Never to retreat and never to yield.

I Deny the Nothingness to embrace the hills of Weapons.

For The Everdistant Utopia, I declare.

Master of Arms."

Power erupts from Shirou like a surging tidal waves, freezing the air and ruptured the earth beneath him. The sparks of lightning from his cloak began to intensify with the additional flow of prana entering the sequence of runes. The sudden flux of power wasn't the only thing that changed. His hair is now slicked back with a strange glow, his eyes also changed too. Shirou's iris now glow a magnificent shade of gold while his pupil turned into slits. Still chanting, Shirou's Mystic Code also changed as well.

"The LORD is my rock and my fortress and my deliverer.

My God, my rock, in whom I take refuge.

My shield and the horn of my salvation.

My stronghold and my refuge.

Though I walk in the midst of trouble.

You will revive me.

You will stretch forth Your hand against the wrath of my enemies.

And Your right hand will save me."

This time his entire outfit changed to that resemble what a normal priests would wear. A black cassock with a white shoulder cape with ribbons on either side of his chest and a white sash wrap around his waist. The armor plates however stayed on his shoulders and arms. Disregarding his handguns, Shirou spreads his legs past his shoulder, bending at the knee. Both arms folded in with his right held close to his face while his left in front of his face.

The basic stance of Baji-quan, in which was perfected for Shirou's own use and style.

Before Lancer could comment on his change of attire, Shirou 'moved' to where Lancer is posing to strike at the man with his elbow. Not letting up Shirou punch viciously at the shaft of the spear hoping the man would bulge. Jumping back, Shirou goes for Lancer's ribs with a kick but the Heroic Spirit leaned to his left dodging his kick. Spinning along with the momentum of his kick, Shirou lunged at Lancer aiming to punch the man on the head. His block was block again but manage to push the Servant back.

"That is some punch there kid!" Lancer said.

Ignoring what the man said, Shirou continue to press his onslaught. Trading blows for blows with the Heroic Spirit.

Suddenly, the lancer stop blocking and swings his lance to push Shirou back so he can use the advantage his lance has.

But it was stopped.

In Shirou's hands is a spear. A spear that is two meters in length and made from lightning.

With strength he never had before, Shirou pushes the blood red lance away from him before jumping back a few feet behind him and adopted a stance similar to the Heroic Spirit. Tensing his muscles, Shirou once again pounces at the taller man determination burning in his golden eyes. Prana still coming out from him in waves.

I am the bone of my arms.

Like a gust of divine wind, Shirou's lance soars to meet the Spirit's own lance. Steel against lightning. Servant against man. The clash between them resembles a dance.

A dance of death with sparks and bolts of lightning and steel. Each aiming for the others heart.

My body is the forge and my blood is my forms.

The two men are no longer men. They became beast that reeks of bloodlust. Thrusts is parried and swings are blocked. Neither men willing to stop this clash.

Have mastered over a thousand forms.

Lancer evade a swing from Shirou and backpedaled but Shirou refuse to give the man the satisfaction of breath.

"Arms. On"

Countless lances of lightning rained down on Lancer from behind not letting him escape. The lancer tried to change direction but the lightning lance follows him. The Irish hero had bit back a curse as one lance that came too close.

Suddenly he raised his lance just in time to block a vicious swing from the red head forcing him to bend his knees while cracking the earth beneath him in the process.

Unaware of the first.

Nor aware of the last.

Withstood lost with countless masters to be the master of all.

Once again, both men continue with their clash.

Lancer is now getting nervous, the amount of prana being build up is staggering and his master is being unresponsive. Lancer has the right to worry, he has clearly underestimated this young man before him. How come one this young be able to match him, especially in this era, and he was even trained by the legendary Scathách.

Yet my soul shall master none. Still striving for more.

Seeing the Servant's pensive expression, Shirou smirks showing the first sign of emotion since his change.

"You want to know how I'm matching you in the art that you're so famous for?" Shirou asked, adopting an amused expression. He smirks further at the Servant's irritation.

"Then you shall have it."

Jumping back, Shirou spread his arms wide with the proudest smile on his face as he unleashed more prana than before. So much that his circuits became visible under his skins and outfit with wisps of prana exudes from his body like a flame.

"So as I pray to you, grant me my wish, grant me!

UNLIMITED ARMS WORKS!"

Rin Tohsaka is getting worried. Not an hour ago she escaped barely with her life. Her own Servant was just a few second away from being skewered by the opposing Servant when the most unexpected person appeared.

Shirou Emiya.

Not even a second after he ran away, Lancer followed him. But as she give chase, Rin did not come across the corpse of Shirou Emiya. She immediately rushes to his home in case he ran back home. Nearing his house, just a couple of blocks away, she felt an enormous amount of prana gathering where Shirou's house is. She then ran as fast as she could, summoning Archer form his astral form as she did so. Jumping over his walls, she and Archer witness to the most unbelievable scene.

Shirou Emiya is producing a gigantic amount of prana she might as well thought that he is going to use some sort of High-Thaumaturgy. Prana was clearly visible around him, coiling around like a flame. The Servant Lancer was gasping for breath like he just ran a marathon, obviously tired.

The Archer in red was also astonished as well.

'How is he already be able to use his Reality Marble this soon.' Archer gritted his teeth.

'This must be one of those rare cases.' The Archer in red solemnly thought.

The duo is once again astound with what happened next.

"So as I pray to you, grant me my wish, grant me!

UNLIMITED ARMS WORKS!"

And their world was engulfed by a sea of heatless flame.

Once the flame washes away. Everyone was treated to the sight of a beautiful sunset with golden rays of light still illuminating the world. Clouds of orange like flames that covers the whole sky with gigantic metal cogs and gears seemingly fitted together while spinning like they are running something.

Looking around them, all they can see are barren hills with weapons. Weapons that littered the whole world. From swords to spears to axes to guns to shields. And occasionally fighter planes flying across the golden sky and vehicles that carries ICBM. They even saw phantoms and shadows that are practicing forms of combat varying from fencing to kung-fu.

"Welcome to my world Heroic Spirit! My pride and my joy!"

Before Cú Chulainn could do anything, a rain of steel has already down upon him. Jumping back, Lancer could only curse as he is once again force into the defensive to avoid getting hit. Sure he would survive after getting hit by those weapons but he would not rather risk it. That and his pride would be shattered.

Barely after his thought was finished that a very wicked looking sword went too close to his crotch for his fighting.

"Oi! Are you trying to kill me?" Lancer roared at Shirou.

"That's kinda the point!" Shirou shouts back.

Not wasting time, Shirou rushes in with blades in hand intending to cut down the Servant. His resolve strong and unmoving like a fortress wall but his swords was not. Upon meeting the shaft of the red spear, the blades broke but that did not deterred Shirou the slightest. Thousand more blades come to his hands and a thousand more shatter, some last more than a few hits but none did not broke.

*CLANG*CLANG*CLANG*CLANG*

Blade after blade Shirou did not stop, swing after swing each grew stronger after another. His form faster, more flawless, every thrust and swings of the Servant was dodged or blocked.

*CLANG*CLANG*CLANG*CLANG*

Blow for blow, Shirou trades strike with the Servant like he's in a spar. A spar that seems going on and on.

A stalement.

A stalement that Shirou would not allow.

"Chase your prey. Hound of the Red Plains."

"Hrunting!"

Calling out the Noble Phantasm's name, Shirou summons the legendary blade belong to the Hero Beowulf. A pitch black long sword with wave like pattern as its blade. A sudden burst of bloodlust exploded from both the sword and Shirou.

With the arrival of the blade came along with a more vicious barrage from Shirou. Swings and blows coming from Shirou is beginning to strike too near to the lancer's body and with the black blade assisting him to find his opponent, Shirou began on focusing his mind on summoning his blades and spears of lightning to shoot at the Heroic Spirit from different angle.

Even with Battle continuation in his class skill, Lancer can still feel the ache in his pseudo muscle. The kid just keep on pulling out trips from his pocket.

Literally.

He had to dodge a knife that came from the kid's pocket!

How in hell could the kid have strength equal to a Servant. Not to mention the kid can still fire those blasted lightning spear of his along with really sharp swords. He had to put all stop and finish this quickly. Swinging his spear wide to force the kid to dodge, Lancer jumped high into the air and activated his Noble Phantasm.

"I'll have your heart!"

GAE-BOLG!

And red filled everyone's vision.
