A/N: This fanfic is credited to worldwanderer2.0. This also run parallel to my other F/SNxFGO fanfic called Irregular Singularity. Which is a (noncanon)spin-off of this fanfic set in between Epic of Remnant and Part 2. It also where I have my game ID if anyone wants to add me. I play Fate GO almost obsessively.

I wanted to hurry and post this in celebration of rolling Karna and the Craft Essence I wanted for Saber Wars on NA. I'm still waiting on another copy of Nero on her rate up. The Gacha still brutal anyway.

"Trace on", Shirou traced Kanshou and Bakuya, the married blade, as he fends off another gandr shot. The ball of energy hit the blades in a metallic clank.

Shirou dodges more shots coming at him all the while blocking with his dual blades. He didn't want to hurt her and neither did Tohsaka.

He could close the distance between them but risk being hit. Even going off of how Rin perform in her self-defense class, she wouldn't crumble as easily.

He no longer has Avalon inside of him to take the hit and heal.

"Shirou", She shouted,"Give up! It's over. The Enforcers will be here soon. There nowhere to run. I can't protect you from what Illya did. What you did!"

"Sorry", he apologizes,"I can't turn myself in."

"I understand", Shirou threw both his blades at Tohsaka and she fired at them. They exploded creating a cloud of smoke.

At the same time, the young teen turns tail and ran with reinforced legs.

"Damn Shirou!"

She sprinted after him.

"Search the area", A Enforcer commanded to a trio of his colleagues," They shouldn't get far!"

They split up into pairs. One of them heads to a dorm room with the doorway slightly held open.

A young woman with drill hair looked through the slit and greeted them.

"What seems to be the problem?"

"Lady Edelfelt", One of them introduce,"We're looking for two fugitives, Illyasviel von Einzbern and Shirou Emiya."

"Why?"

"One resisted a sealing designation and the other badly injured an Enforcer in the process."

"It affects me how?"

"We need to check the room Miss", the other asked before a large explosion caught their attention. It was nearby as the fireball brightened the night sky. Emerging from the smoke was a silhouette.

It was Shirou sprinting across the campus.

"It's him!",the enforcers started chasing Shirou.

Luvia signed in relief and close the door.

"The coast is clear", she said to the only other person in the room.

A closet door open and a little girl with long white hair and red eyes step out. She was wearing an ankle-length violet skirt and dark violet button up long sleeves.

"I didn't mean to hurt the Enforcer. A sealing designation is basically a death sentence to a magus", She said meekly before her tone become cold and threatening," That is why I'm not letting anyone touch my big brother."

In the Clock Tower definition, a sealing designation is viewed as the highest honor to receive. Said person is important to the association and they will do anything in their power to capture them. The problem is that a magus present ability and condition will be preserved for the Association to study. Resulting in a magus having to abandon their lifelong work.

One of these works is a new path of Mage craft Shirou created through Projection and tracing.

"I can only do so much to help without ruin myself in the process", Luviagelita motioned," I apologize but you are on your own. There an underground passage for you and Shero. It's near the self-defense class and another in the garden."

"Thank you for all your help Lady Luviagelita", Illya did a bow with her purple dress.

"Just escape before someone sees us. Besides, I don't even live in the dorms. People will start questioning me", She sidestepped and opens the door in the process.

"You're a pretty cool person Luvia for helping me", Illya ran out and into the hallways.

'Got to find Big Brother', She thought to herself and stop in her tracks.

Someone was nearby.

Illya reacted quickly and pulled strands out of her hair," Engel Note: Angel's Poem!"

Four white bird shaped familiar appear in the air above her; Two of which turn into swords and launch toward a dark corner of a ceiling.

Someone immediately drops from the ceiling as the sword embed itself onto the marble ceiling.

The girl that stood in front of Illya was someone familiar yet different. She wore an all dark grey jacket accompanied with a light grey skirt that has white and black patterned design, slate grey stockings and black boots with a Clock Tower brand logo on them.

She was in a prone stance as the night sky kelp Illya from seeing more of her. She can make out what she's wearing but not her face.

The mysterious girl stood up and walk slowly toward Illya. The moonlight finally giving off enough illumination for her feature to be clear.

"Saber?",The half homunculus whispered under her breath,"Wait!"

As the Einzbern observe more of 'Saber' features. It becomes clear that she has light gray and not blonde bangs. The eyes are the same blue color but Illya sense this person isn't as her brother and parents servant in the Holy Grail War.

"Please stop. I-", She spoke with hands at chest level before looking overhead to see the dual blades falling on her.

Gray leap out of the way as Illya familiars fire small blast in rapid succession.

Illya halted her attack to realize how the Saber was having no difficulty avoiding Illya attacks.

Gray kept her calm and quiet visage without a single bead of sweat on her forehead. She raises her weapon and dashed at Illya faster than any magus even with enhancement.

Illya brought her remaining two birds down and shifted them into a shield to feint off what she thought was a slash.

Instead Gray used it like an Olympic polearm to strike the ground and leap over the defenses. Illya turned around to see Gray land and spun the scythe. It struck her with the flat part of the blade, sending Illya flying into a wall.

Small cracks form and the 19-year-old girl hit the ground with a thud.

Gray signed sadly knowing she struck the intended target a bit too hard as blood leak of the homunculus. Illya eyes were blank.

She walks away only to swing the scythe behind her on reflex.

Illya pushes herself off the ground with red iris burning brighter than the hottest flame.

The Grim Reaper ready her weapon as the child grasp her chest with a face of relief knowing why she's still alive.

It once belongs to the King of Knights.

It was discovered and passed down to the vessel of the 4th Holy Grail War to extend her life.

It saves her father not once but twice.

It then belongs to the only family she has left.

Finally, it was passed on to her. The fable scabbard, Avalon.

The two eye each other waiting for the first move. Then, Gray strikes first with a quick burst of Prana into her legs.

Illya reacted by quickly reaching into her pockets and throwing the various assortment of strings like material. In less than a second, they foamed into white swords or familiars.

The young Einzbern typically use her hair that uses pump with prana as a way to summon familiar. But a joking remark from Rin about finding an alternative or else she may go bald forced Illya to use other string like items to use. Some of them being metal wiring and fishing line. Although unlikely, she listened and decided it was a valid idea.

Gray was under fire with renewed intensity. A dozen familiars attack her as she kept dashing out of the way, deflecting the occasional swords flying at her.

Illya breathed heavily knowing she pushing herself to her limit to deal with the Saber lookalike. The body of her's being 70% magic circuits was being overworked against Gray even if most magus would have died from the onslaught. She could make four Engel Angel's easily but since she no longer held down by a servant, namely the difficult to handle berserker, which takes a massive amount of prana to supply. Illya could now make many more of them.

The birds fired in rapid succession while the blades floated near the child as a defensive measure.

Gray weave around the shots with a lot of difficulties until she notices the magical energy from those familiar is creating a large dust cloud.

Illya remains in place as the swords surround her. The reason why she isn't running or moving is due to the amount of prana needed to sustain her defense and offense. Plus, Illya observes that she wouldn't be able to outrun the saber lookalike with her higher than normal agility and speed even for a magus specialize in close quarters combat.

It was in that moment Illya started to realize her own mistake and stop the bombardment least she wants to start firing blind.

It was too late when a winded Gray slips into the dust cloud and out of sight.

"Where did she-", the young girl flinched as the reaper weapon came at top speed from her left.

All her familiars fire in rapid succession as quickly as machine guns of white energy and the swords came automatically to defend Illyasviel.

She hears the clink of the scythe as it impacts her swords.

She opens her eyes hoping the barrage killed the saber clone.

The weapon was on the ground without it wielder. The young Emiya realized the intent and turn toward the source of footsteps.

The white familiars and sword which were facing the opposite direction didn't have time to intercept the real target.

The last thing Illya saw was an elbow.

"The target is secure. I'm bringing her over", Gray reported after retrieving her mystic code, Add. Who transform into his more compact form of a birdcage.

She then walked over carried Illyasviel bridal style as sleepy students and faculty members rushed to the scene.

She didn't feel like explaining how this is Association business and no one should interfere. Actually, she doesn't feel like talking to anyone, period.

Gray quickly got out of the area as more witnesses survey the scene.

Shirou PoV

I avoid letting them get near me. I don't have to be an expert to know that Enforcers tend to specialize in any field involving the killing or capturing of a designated target. Whether it's close quarter or the shadows if a single one comes after me then maybe. But seven of them while being in the headquarters of the Mage Association?

Maybe I would have turned myself in if they were really out to arrest me.

It all started yesterday when Zelretch called me into his office. He asked for my help to deal with a situation, an invite to a place called Chaldea. It was on a simple white envelope with only the address with the numbered coordinate located somewhere in Antarctica. It was a strange meeting because we only have small talk until he gone cold and silent. That when he handed me the envelope and kicked me out.

His last words before closing the door were,"They're coming. Prepare to leave and I'll tell you more."

That when everything went to hell. I didn't get to read the letter inside yet when an Enforcer came knocking at the apartment Rin, Illya, and I was staying. One event leads to another and now I'm on the run.

I was cornered. It was 3 brick walls behind and to the side of me.

There nowhere I could run and despite a sealing designation being a 'high honor'. I will become the Clock Tower experiment.

But there another reason, Someone in the Clock Tower views me as a threat. The same enforcer that tried to place a Sealing Designation nearly lost his life because of my sister if it weren't for Illya, I would have died.

Somewhere along the way, I was blamed for an action I didn't do; starting an Apostle Outbreak despite being the one to stop it.

I'm starting to really hate the Mage Association for what it is. Someone higher up only wanted a reason to come after me, which is why I ran. I didn't want to abandon my search for Saber nor my tracing.

I was in deep and anything I'll do next isn't overstepping any boundary I pass long ago.

My circuit burned as I sense the team of enforcers synchronizing their shots.

Some fired stream of flames, gandr's, a saw off with human fingers of all things, and other beam or elemental magecraft.

I close my eyes and dematerialize my sword.

I thought of the archer in red. He was just a nameless archer in the Holy Grail War before then. I would have never guessed it was me, EMIYA.

It was when Tohsaka told me about her servant real identity that I decided to imitate him. I saw how he fought and from memory, I copied his swordsmanship, his magecraft, and his technique.

Day by day.

Month by month.

An entire year passed as I copy him. As I trained my magecraft and my body. I may not know everything but I got the basic of how his archery and weapon creation works.

I started to dream of a hill of blades from more often than before.

I will use that knowledge to get out of this situation alive.

I must stay alive.

So I can seek her on the reverse side of the world.

In the garden of Avalon.

They're getting ready to fire everything. What could I create to counter it?

An image of EMIYA pop into my head with his back facing him.

'Imagine something that can defeat it'

What could possibly defeat this?

I wasn't sure why but I instinctively raised my right arm.

"Rho Aias", I chanted and a purple shield formed. It first was 4 pedals and then it overlapped with 4 circular shields.

The magical and nonmagical elements from the enforcers were deflected with ease. While it put a strain on my body, it wasn't enough as one of the shields are yet to break.

They finally stop as I lowed, 'Rho Aias'. Now that I prolong my life for a few more seconds to realize I created something I have no prior knowledge of, yet it felt like I done it before.

I try projecting Kanshou and Bakuya again but failed. My prana felt like it's all been used up. Every last bit of it.

Suddenly, Someone dropped a smoke grenade followed by a flashbang.

The two went off simultaneously as I grasp my head and eyes from the stinging.

"Grahh!",I gasped and felt someone tackled me. I thought I was going to either hit the brick wall or the cemete ground. Yet, somehow, my back felt like it landed on wood flooring by the distinctive sound.

Despite still being blinded and partial deaf; the ringing was still fresh in my ears. I punched the person that tackled me off. I felt it hit her when she gives a pained yell. She got off immediately.

When I came through I was speechless.

"A-Artoria?",It was the only thing I uttered as I try to embrace her. She shies away with a look of disgust and before I knew it I felt a swift kick hit me right between my legs.

I crumbled to the wood floor in absolute pain. I wanted to vomit from what just happened.

'Why Artoria?', I couldn't help but think what would force her to resort to sure means.

"I'm not the King of Britain", She spoke sounding a lot like Artoria for someone that claims not to be Saber. I force my head up to look at her through blurry vision and my first reaction was how is she not the King of Britain, Artoria Pendragon?

As my vision clear from both the flash bang and my watery eyes from her...responds.

She has pale blue eyes instead of Saber lively azure. Her hair isn't blonde but light gray.

I was on edge because if that not the girl I love then who is she? I was fighting for my life one moment but now I was in an office with this lookalike.

She reaches a hand out toward me. I hesitated at first but since I felt I wasn't in any danger.

"My name is Gray", She introduces,"Shirou Emiya was it? I'm the one that rescues you."

"Rescue me?"

"Look around and tell me if their anyone trying to kill you", She spoke calmly.

I wondered how I got from a dead end to here. I can tell the set up is someone private office. I scanned my surroundings and a sense of familiarity hit me. I grabbed her hand and she pulled me up.

She still looked very annoyed with me and I remember when I did moments ago, "Gray, sorry for trying to-"

"Rejoice boy!",We turn to the source. A wooden desk with the back of a hardback swivel chair facing us.

My hands distinctly clenched and I felt a brow twitch. Of course, that how I escaped.

"Old man."

He turns his chair and was facing us now. A wide grin on his face.

"If great seeing you again Shirou. A charmer with the ladies as always", Zelretch looked at Gray," Sorry if he was trying to force himself on you. You just look exactly like his lovely ex."

Gray turn away, pulling her hood up. I swore I saw a faint of pink on her cheeks.

"Look, I want to know what the hell going on? When my little sister Illya?",I questioned him. I walked angrily forward and passed two chairs and places both my arms on his desk,"The last 24 hours have been nothing but crap since our meeting and I demand an answer."

"Unfortunately, It something's even I can't stop", he took on a serious tone," There people, things out there that far more powerful myself. You fought a Holy Grail War Shirou. It easy to realize what it could be."

Something this old vampire can't stop? Zelretch is considered to be one of the strongest in the ClockTower and possibly the world not counting servants or even phantasmal creatures.

"Where my sisters?"

"You just walked passed her."

I turned around and saw the two chairs I walked passed. One of them has the sleeping or unconscious Illya with a blanket covering her.

"I have to knock her out. She didn't want to listen", Gray commented as I look at her with killing intent before softening up. It definitely sounds like Illya attacked first, again.

"Emiya, I recommend you take a seat. All the running must have really worn you out", Zelretch motioned to the empty chair.

I didn't feel like protesting because every part of my body ached from everything that happened.

I sighed and sat heavily. Exhaling as I realize how comfortable this chair is. I try not to doze off but my bagged filled eyes tell me otherwise.

"I'm now the most wanted man in the Association. There no place for me to run is there?"

"Yes, but I will give you an offer that will fulfill both of our wishes."

"What the offer?",I asked as he leans forward.

"I want you to join Chaldea. They will protect you from the politics of the Mage Association."

"What if I refused?"

"Shirou, I will guarantee that you won't regret joining."

"I'm still skeptical. What will I gain from joining?"

He nodded and got up.

"An opportunity for you to save humanity with those who want to become a hero just like you. The only catch is that it will be in another world and another time, ten years from now to be precise", he explained,"Gray shall accompany you. While Rin currently packing your essentials for the trip."

"Rin?",I was shocked. It was half an hour ago she tried to turn me in.

"Did you really think she betrayed you?",Zelretch looks amused,"Tohsaka has to turn on you first so they wouldn't think she's collaborating. After that, I can make sure no harm befall her."

"Could she come with me?"

"No", he shot down my question," She'll 'sort of' come another time."

"Sort of? What do you mean?"

"Oh, you'll find out. Rin's 'kind of' joining Chaldea in a strange sense. I can only send in a few people, without him knowing: You, Gray, and Illyasviel. Then there forging your false identities. "

I heard someone running behind me.

I turn around to see a metal double door. Moments later, it was kicked open by a frustrated and exhausted Tohsaka Rin. She was wearing a red button up and business skirt with black leggings.

She was hauling several bags and briefcases in her arms. She unceremoniously dropped all of them upon seeing me.

"Emiya-Kun!",she pushed pass Gray and felt her arm wrapped around my neck,"I'm glad you're okay. I was worry you wouldn't forgive me for what I tried to do."

She releases her embrace.

"I would never hold anything against you. It was unfortunate but I would understand why. My life isn't worth sacrificing you and your family reputation."

"Hopefully, I got everything you need."

"Thank you."

"Emiya Shirou", Zelretch voice boomed,"What will be your decision? Will you remain here, hunted down by the Association, the Church and anyone after your bounty or will you live out your dream as a Hero? How would you like to meet Artoria sooner?"

Artoria? Is he serious? The person I have been seeking. It sounds too good to be true.

"If my life here is ruin then I don't have much of a choice doI? I accept it."

I honestly don't know what Zelretch planned for me and what exactly is Chaldea. The only thing I have to go on is a chance to escape the Clock Tower, become a hero, and against a powerful enemy. Even if Zelretch the one pulling all the strings, there isn't anything I could do. I hope he keeps his deal if I'm able to be reunited with my servant, the girl I love.

The old bastard normally entertain himself by pranking someone but getting me on the Mage Association most wanted list? That's a sick sense of humor he wouldn't stoop to; hopefully.

But what if he genuine trying to help me against the ones that orchestrating everything is another possibility. He could kill me easier but Zelretch would do anything to help humanity so the offer to join Chaldea align with what the old wizard wants.

"In that case!",he lifted both arms the room started to disintegrate into a white void. The only thing in it is us, the chairs Illya and I are sitting in, and Zelretch with his desk and chair,"Let begin a Grand Holy Grail War to save the world!"
