[Unknown Place]

Shirou Emiya looked at the setting sun as he relaxed atop a lonely cliff in an endless wasteland filled with small orange-black crystals. He was dressed in a simple red overcoat, a simple white shirt, burgundy pants, and a set of black combat boots. Sighing to himself, he manifested Kanshou and Byakuya into his hands and observed their beautiful craftsmanship while he tried to figure out the reason why he was transported in this strange world and in his 10-year old body.

No matter how much time has passed, Shirou could not figure out the exact reason how he got here. It could not have been either Alaya or Gaia since their presence did not exist within this strange world. He did not think it was that Old Troll as even he had his limitations which plagued the question 'Who or What sent him here and why has his body de-aged?!'. Shirou dismissed his favorite set of weapons as he started analyzing the new weapons he obtained after entering this world. He did not know how they appeared within his Reality Marble but after realizing he did not know how he got in this new world, he decided it would be futile to comprehend how they got there.

As he looked at the new list of weaponry, he saw an interesting nodachi that shined an ominous red but no matter how hard he looked, he could not exactly determine any of its abilities or features as it was shrouded in a deep red mist. Before he could determine the issue, he heard a loud rumbling in the far distance. Shirou instantly stood up and rushed towards the sound so that he could check what it was exactly.

Reinforcing his legs, he began to rush faster than a cheetah towards the source and when he arrived, his face became pale-white. There was a city that was moving as if it was a vehicle but that was not the problem. The problem was the gigantic behemoth that was rushing towards the escaping city as it tried to destroy it. Using Hawkeye, Shirou observed the peculiarities of the monster before he engaged it.

The monster was covered in plates of rock-like armor but there were visible gaps in between its joints to facilitate easier movement. The behemoth had four glowing yellow eyes that were not seemingly protected by anything and it was standing on four limbs similar to tree trunks but fortunately, his lower limbs were much smaller and weaker.

Clenching his teeth, Shirou summoned his favorite blades and pushed himself off his vantage point. He reached the aberration in a matter of second but it seemingly ignored him due to his diminutive size. Grabbing his blades in a backhand grip, Shirou moved swiftly to the back legs and he fell like a thunderbolt on his target.

Despite his weaker body, Shirou easily managed to cut through the exposed part and sever the ligament but his momentum stopped so he had to retreat quickly as the beast screeched in pain. The monster tried to backfist its attacker but it was quickly met with another bout of pain as its other lower limb met with the same demise. Screaming in anger, the creature sends thousands of stray rock shards towards Shirou and it started spewing flames in a futile attempt to scorch its aggressor alive.

Shirou had to quickly evade the projectiles and incoming fire which was hard even with his Mind's Eye active. He swiftly made some distance and looked at the city before he realized that it stopped and a lot of citizens were watching him. Some were even cheering for him which was pleasant but he was more worried about their safety. Therefore he screamed to them, after altering his vocal cords.

"WHAT ARE YOU DOING?! RUN AWAY"

As if it was on cue, the horrific creature threw a nearby boulder at Shirou as it was immobilized. Reinforcing his legs, Shirou jumped away agilely as he understood that his previous tactic wouldn't work because the beast was fully focused on his every movement. Dismissing his blades, he considered which weapon would promise a certified kill before he smiled and summoned his altered bow(for his body size) and a very specific sword. The sword was emanating a frightening aura as if it was a wolf stalking its delicious prey.

Upon getting enveloped in that aura, The beast screeched and sent a pure wave of flame, and using its two remaining limbs, it started crawling at a fast past. Calming his heart, Shirou drew the string and released the wolf with a few simple words.

"Hunt it down, Hrunting!"

In an instant, a red beam exploded from the bow and the blurry silhouette of a black-furred wolf appeared as it opened its horrifying maw when the arrow pierced through the beast's eye and perforated the skull. The beast could not say anything before the back of its skull exploded in a huge gory mess.

Shirou fell on the hard cold earth as he examined the wounds he obtained. Although he did not seem very injured, the constant reinforcement and summoning of Noble Phantasms took a toll on his body. He looked behind him and saw that the city had not escaped but they kept on cheering him on. He put his hood over his head but before he could do something, he rushed towards the corpse of his victim despite the pain he was in.

The corpse started to become bloated and a wave of heat spread out from it before a huge fiery explosion spread away from it. Shirou's eyes widened as he realized that if he dodged, the city would be in danger. Although he had a lot of shield within his armory, he knew a specific one that would guarantee his chances when he needed no unnecessary testing. Spreading his palm, he brought the shield that had the protection of multiple fortresses.

"RHO AIAS"

Using the last drops of his energy, he made the powerful shield cover the entirety of the shield but the impact was pretty powerful because Shirou was slowly being pushed backward. Clenching his teeth, he screamed in protest and thought with increasing determination.

'I WILL NOT LET ANY OF THEM FEAR'

'I WILL CONTINUE WALKING ON MY PATH'

'EVEN IF I FACE DEATH RIGHT IN THE EYE'

At that moment, in Unlimited Blade Works the mist around a certain nodachi started dissipating. The aura of the blade leaked through and it represented the combined might of every blade within his world.

As the powerful wave of destruction receded, Shirou's haggard body swayed to the side as waves of pain traversed through his body. He looked behind him and saw through his blurry vision that the city was safe and sound. Smiling to himself, he started walking away from the city as small golden particles started recovering his skin. When his wounds have completely recovered from the strange wondrous artifact, Shirou ran faster than he ever did.

[Much later]

Shirou did not know how long he has been running when he found another city that was on the same platform as the previous one but it was not moving. Thinking about it for a second, Shirou reinforced his body and started climbing the city while he evaded any detection methods from the city itself.

Arriving inside the city, Shirou arrived in a distinctly poor and unmanaged district with no visible people. As he was observing the situation, he saw a small girl with black hair, blue eyes, and...cat ears fall on the ground(he did not notice before). Widening his eyes, he rushed towards her and cradled her head as the rain was slowly falling on top of him. The girl had strange blackish sediment, growing out of her skin. His soul was shaken to its core when he realized that it was similar to the one he found on the ground.

Looking around, he rushed into a small dark alley as he could feel the girl's pulse grow slower by the second. Cradling her head, he looked into his being as his body started emanating a yellow glow with a welcoming warmth. The girl's exhausted eyes widened as she saw a beautiful spectacle unveil before her.

Shirou didn't know why Avalon was working so well without Arturia but he could relate it to the strange fire pulsing within his blood. Dismissing that thought, Shirou enveloped that girl in the warm aura as he watched the shards start vaporizing slightly before they stopped. Confused, Shirou tried to do the same thing again but he was met with the same results when the small girl placed her palm on his cheek and said.

"Thank...you. Thank you. You gave me more time! I am so happy that I could take care of my brothers and sisters more."

Seeing such pure bliss, Shirou's mind was made up. He would save her and her family and give her a new chance. Powering his magic circuits, he channeled all the energy that has accumulated during his travels into Avalon and his...blood. Tightening his teeth, Shirou pushed through the pain as the brilliant aura started growing stronger and stronger. As the aura grew, the small shards started disappearing but the girl started turning hotter as well. When the temperature started entering dangerous territories, Shirou dismissed the aura as he looked at the smiling girl whose black shards have...mostly disappeared.

"What is...your name, Onii-chan?"

Shirou smirked at the name as he thought what he should say in that specific scenario. He was Nameless while he was an Ally of Justice but he was also Shirou Emiya at the same time. However, he lost those names when he arrived in this new world yet he is still connected to them through blood, memories, soul, and Reality Marble. Therefore he spoke the name that embodies everything that he is and he will become.

"I am Archer."

"Archer as in bowman, the guys who shoot bows and protect us from the beast. Then you are my hero!"

"Yes, dear. What is your name?"

"My name is...Shiroe"

'Fate likes to fuck with me' Shirou thought absent-mindedly as he supported the weak girl before he said with a kind smile.

"Let's go to your home, Shiroe"

The little cat girl smiled slightly as she thanked whatever god there are for her new hero. She looked into his amber eyes and said excitedly.

"Yes, Onii-chan!"

[Line Break]

Well, I decided to make this small chapter since I was kind of bored. I don't know if this will be a new thing but I thought how would the world change if Shirou existe in the Arknights world.

Shiroe will become important later on and I got my idea about her when there was a small cat girl in the trailer for Arknights. Anyway, take of yourselves you beautiful people.
