AN: Well, It's back, I hope to do as well as the 4th war, if not better, I will not be including any Servant stats within this chapter as it is only a prologue. Since I did not cover what had occurred between the 4th and 5th wars, I shall sum it up quickly and go into details within later chapters/parts.

Two months before 5th War-

The brown haired girl smiled at the circle in front of her, holding onto the sketchbook of her drawings as she recited the chant one last time. Calmly she set the book aside, and said the chant, expecting the light and slight noise of her uncle coming to check on her. Just above the command seals still remaining from the last war a new set appeared, what appeared to be a rabbit half on fire and half-frozen was what greeted her. Blinking somewhat at the strange set of command seals she looked back at her Servant and immediately found the reason for the rabbit.

A girl appearing around the age of eight met her gaze, one blue eye and one red eye meeting her gaze from under half-white, half-black hair. The Servant wore a blue hoodie with a large cowl, blue pants and red boots, holding a rabbit puppet in each hand. The right puppet was white with red eyes, a cheerful smile in place and giggling emanating from it, the left puppet was black with blue eyes, a frown and tears etched onto its features while sobbing was heard.

The Servant the girl summoned did not speak, the right rabbit speaking instead. "Hello, I'm Lea, that's Caster and that's Ael." Somewhat unsure of how to respond to that she saw the other puppet look at the white and talk with sobbing mixed in. "Lea, it's not our place to talk for Caster in introductions, she might get angry." The other rabbit somehow shivered at the words and quickly apologized to the apathetic-looking girl.

Kariya walked in mere moments after the exchange took place, looking between Sakura, both sets of command seals on her wrist glowing red, and the small girl with the two rabbits. With a sigh he looked back to Sakura and asked, "I guess I have to book us a stay at Fuyuki in several months," a sigh, "And I thought we put that place behind us."

Sakura looked somewhat sheepish at his words until he pat her on the head. "No worries, I don't have anything urgent coming up, and if worse comes to worse you can stay at the Emiyas'." Sakura beamed up at Kariya, hugged him and went back to her unmoving Servant. Without a word Caster went into Astral State, her Master looking with a saddened look before leaving the room to get ready for the trip to Fuyuki.

1 month before the 5th War-

The Wizard Marshal was wandering the halls of the Clock Tower, a violet-haired woman walking slightly behind him. While she had an otherworldly appearance, it was not noticed due to the scrambling to get out of the way of the known prankster. It was only when they arrived at their destination and its occupant did anyone actually note anything about her.

A silver shirt, grey skirt, black shoes and white gloves, two overlapping 5-pointed stars on the back of gloves made up her wardrobe, a simple purple half-mask hiding her upper face from view. The strangest thing about her was the pure-black dodecahedron at her waist, it held an air of mystery comparable to Noble Phantasms to one who had seen an object of that classification.

The two entered the office of the Vice-Director, finding the woman with hands stippled at her desk, a set of red markings in the shape of a sword on her right hand. She looked at the two that entered, narrowing eyes flickering to the right hand of the User of the Second Magic, noting the markings there in the shape of three muskets. The Dead Apostle Ancestor and Dead Apostle-slayer simply stared at one another, neither choosing to speak for different reasons.

After a long period of silence, the Vice-Director spoke up, her voice tinged with cold, "Zeltrech, can you please explain to me why I have a set of Command Seals." While phrased as a question, the sentence was more of a statement or order, though many magi would leap to answer just to avoid her wrath.

Zeltrech opened his mouth to reply, "I have no idea." At her somewhat incredulous stare, he showed his own set of command seals, "I shouldn't be able to get Command Seals, yet here they are." The Vice-Director looked over to the woman who was now looked at the various objects scattered around the room with childish wonder.

"I assume then that she is your Servant." A nod answered her question and she let out a slight sigh, head resting in her hand. Zeltrech and his Servant left shortly after, heading off to just let time pass in preparation of the War. The Vice-Director got up and grabbed a simple tome, opening it to a specific page before reading it quickly.

2 weeks before the 5th war-

The red-haired teen walked down the dirt path towards a small town, fire illuminating the night with screams of pain echoing out. The boy wore a simple white kimono with a black obi, white boots, and a katana sheathed at his left hip. He casually strode into the burning town, past the Executors that had assaulted this place and into the burning streets filled with the undead.

A ghoul lunged from a rooftop, the sheathed katana meeting it as the creature fell into range. Blood splattered across the cobblestone, the ghoul's body dropping beside the teen, its head no longer existent. Golden eyes watched emotionlessly as the Dead converged on him, ready to begin the slaughter.

Three came at him from the front, a single horizontal swipe saw them flying back in two pieces each. The swipe turned into a swing as the boy continued around to impact another ghoul in the head, the entirety of the appendage exploding into blood and bone. Another ghoul attempted to harm him, missing and receiving a blow to the waist severing the legs from the main body.

A ghoul tried to attack from behind, the once female human unexpectedly hit air, then all was black for the undead creature, its entire body making a crater. The boy stood up from his crouch, hand still grasping the once-human's head, listening to the growling surrounding him. Letting go of the head he grabbed one of the legs and utilized the deceased body as a make-shift projectile, sending the object to collide into a pack of the dead.

The boy followed directly behind the missile, moving at a speed beyond what many humans could comprehend. The teen walked past them, putting the sheathed blade back at his waist, blood staining where there was once bodies. It continued in a similar fashion until the creator of the dead came into view.

The boy did not bother listening to former-human's monologue, unsheathing his sword and doing a quick swipe in the general direction of his target before resheathing it. He once more ignored the vampire, watching in disinterest as it stopped suddenly, it and the building behind it cut in half, the top portions of both sliding to the ground. The vampire attempted to stop its destruction, almost missing the boy now standing behind it and the words he spoke. "You're weak, I hate fighting weak opponents. You're foolish, I hate fools." The vampire's head then now longer existed to hear anymore, along with the rest of its body.

The boy strode out of the flaming town, past the Executors, some of which were whispering about something, likely younger ones. He didn't much care to stop when they called for him to halt, heading back the way he had come, he had to return to Emiya-sama and Nee-sama.

12 days before start of 5th War-

The seals glowed brightly as they were seared into her hand, a simple octagonal shield with a circle in the middle being the shape, the light dying to reveal her Servant. Blue plate made up the majority of his form, a red pauldron on the left shoulder and a violet on the right shoulder were the only different metals, a white cloak hanging from the left shoulder covering the upper part of the arm. Green eyes opened from under blonde hair tied in a short ponytail, an air of melancholy surrounding the figure and infecting his gaze as he looked up at her.

His sword was planted in front of him, gauntlets placed upon the black hilt as he waited for the smoke to fully clear, then asking his question the moment it left. "I ask of you… are you my Master, young noble?" A blink of her eyes was the only betrayal of confusion, a curtsy made to the Servant before she addressed him in voice, "I am your Master, Luviagelita Edelfelt, might I ask what class you are along with what you hope to achieve?"

"I am Rider, this is my atonement for the sins I committed upon the King of Outcasts." While the questions were answered, the one she wished had been answered was spoken cryptically and with a tone wishing not to be spoken about again. The noble quietly left the room, staying only for a moment to say one last thing to her Servant, "We leave for Fuyuki tomorrow, you may do whatever you wish until then."

5 days before start of 5th War-

The Magi was cursing, the smoke revealing nothing after the ritual, resources and a Catalyst gone and wasted. There was an unnatural chill creeping up his spine, going unnoticed in the Magi's anger, along with the seemingly floating grey cloak. A single sword that came from the right sleeve went unnoticed, white with a pommel and black symbol upon the blade reminiscent of the Nobodies of Kingdom Hearts, the tip rounded rather than pointed. With a flash the Magi lost his head along with life, the sword disappearing along with the cloaked being. An Assassin and Executioner was loose to do as it wished.

3 days before the 5th war-

The teen stood in front of the school named Homurahara Gakuen, patiently waiting for his Nee-sama to exit the building. He garnered strange looks from individuals that roamed the streets, both for his age and dress, and from the katana sheathed at his waist until they recognized who he was and quickly averted their gaze. After two hours of waiting he decided to finally go inside the yard, stoic gaze still in place.

He waited moments longer until the bell rang, students exiting the building and passing the teen. They held hushed conversations regarding the boy, some knowing of the boy while others merely noted his being there and left him out of their talks. A white-haired girl skipped up to the teen, now sporting a small smile at her appearance. She had her hands behind her back and a smile in place as she regarded the boy. "Onii-chan! You're back!"

The boy bowed slightly, "Hello Nee-sama. Emiya-sama is waiting for us at the household." The small girl fumed slightly at his addressing. "Onii-chan, I'm your little sister, just call me Nee-chan or Ilya-nee." She ended the short rant with a pout, which did not deter the smile in the slightest. The two walked out of the yard, unaware of the girl that had taken notice of them.

They walked, one in silence while the other chatted about their day, the boy stopping with his stoic expression in place. Ilya stopped behind her brother, her eyes closed and smile still in place, not worried at the group of men that decided to block their path. "… You're not a part of the Yakuza." The boy spoke in a cold tone, unlike that when he was speaking with Ilya, making the men flinch slightly.

The katana and sheathe were drawn, Ilya giving a small giggle. "Otouto, kill them would you please." She spoke with lightheartedness that did not disguise her words' meaning, nor did it reach her eyes. The boy gave his reply to the girl, "Of course, Onee-sama."

He was in the middle of the group of four before they could draw a weapon, the sheathed weapon making contact with one's head and splattering it across the ground and another thug. One drew his gun as the bloodied one sported a hole through his stomach courtesy of the boy, the last thug trying to run away. Eight shots were fired, two impacted the street, three flew past his body, one flew backwards and embedded itself in the fleeing one's leg, tripping the fool, the other two aimed at Ilya were deflected by metal wires that disappeared as quickly as they appeared.

The man lost his arm to the boy, followed swiftly by his head meeting the ground from the grip of the teen, a crater surrounding his corpse. The one who tried fleeing found himself turned over looking at the shadowed form of his assailant, gold eyes staring down at him in stoic silence. "I hate cowards." The man saw no more, the boy walking away from the decapitated corpse, Ilya skipping after him with a slight giggle.

"Are you ready to summon your Servant, Onii-chan?" Ilya's question did not surprise the red-haired teen, merely eliciting a chuckle from him. "Don't ignore me Onii-chan!" The chuckle turned into a small laugh as they entered their home, greeted by their father at the table reading a newspaper, another man who was speaking to their father, and a silver-skinned maid serving simple beverages to the two.

The teen bowed when the two men focused their attention on the arrivals, while Ilya sat next to Kiritsugu with a smile. "Emiya-sama, Velvet-sama." He then went to the kitchen, katana laid on the counter, and started to prepare a light meal for their guest and family. The two adults continued their prior conversation with a nod of acknowledgement, talking about the war slated to happen within the next few days.

"I plan to enter the War again." That stopped all conversation, and two looks of shock looked at the Magus. "Waver-san, not that I doubt your competence, but you barely survived the prior war." The lecturer retrieved something from a box next to him, a simple scrap of cloth. "It's time to fight once more alongside my King."

A brief period of silence, then Kiritsugu spoke again after Shirou set the table with his meal, "I can't stop you from joining Waver. Just know that Ilya and Shirou will be participating, and remembering my luck from the last war, if it transfers, you and Iskandar will be in for hell." Waver gave a short chuckle, joined by his old friend and enemy during the 4th War, they ate in silence until it was nearing night and Waver along with the maid left.

Shirou cleaned up the table while Ilya went off to bed, having a short conversation with his father while doing so. "Will it hurt you to fight one of your mentors?" Shirou immediately replied to the question with his normal tone of voice. "No. My duty is to protect you and Ilya-sama, Emiya-sama. I am your servant, Ilya's bodyguard, her weapon. My duty is simply to serve until my life is gone."

A sigh signaled Kiritsugu's response, followed by actual words with a sad tone. "I truly wish you stopped seeing yourself as such Shirou. You are not my servant, you are my son. You are not Ilya's bodyguard, you're her brother." Shirou merely continued to work, not responding to the last words. "Sakura came over while you were gone, she had a sketch she wanted to show you." The teen looked up and blinked several times, not knowing how to react.

The Ancestor Killer finished his cleaning before once more sitting at the table, directly across from his father. "I assume she is going to be in the ritual as well." A nod from Kiritsugu and a sigh from Shirou, "Well, good things never last, she and Caren are the only ones outside you and Onee-sama that I hesitate to fight."

Shirou got up and collected his sword, "I must take my leave Emiya-sama. It is time to prepare for a short war." With those words he left to his room, the dojo, and performed a set of exercises with the sheathed blade. Once he finished he got into a kneeling position and closed his eyes, lightly sleeping until the next morning.

2 days before start of 5th War-

The white-haired girl looked with curiosity at the creature standing just outside of her home and workplace. It was a strange being looking much like a demon should be envisioned, yet her body did not hurt while near it. It was strange, yet it held no malice or anger, exuding a small of loneliness around it. In its hands it held an arm, torn off from its original place and still leaking life liquid to the ground.

She took one look at the Servant, its shivering form contrasting greatly to its form and suspected origins, and beckoned it forward. The being slowly walked up to her, creeping forward several inches with each step, bolting into her arms and hugging her firmly. If it was capable of the action, it would have cried several tears, as it was the priestess merely comforted the stray Servant.

The seals on the arm transferred over to Caren's own, the child-like being looking up at the sudden comfort its mind felt, Caren merely holding her finger up to her lips, a small smile in place. "Our little secret."

1 day before start of 5th War-

It was time to summon his king and friend once more, laying out the same fabric used to summon him the first time. The chant was said with a tint of nostalgia and a smile, the light blinding for a moment and dust being raised. The Master walked up to his Servant, his smile answered by another, "Welcome back Rider. Shall we go to conquer the world, my King?"

The Conqueror-King gazed upon his Master, a look of recognition in his eyes. His voice was the same as it was ten years ago, exuberant and joyful, "It's been a long time Waver." The Servant became a little annoyed when Waver kneeled, and immediately got back up, chuckling at the same time as Waver when he noticed the grin still in place. "I do believe it is time to go and conquer this War, shall we go, my friend." The Lecturer-Magus took the offered hand, and so once more became a part of the Holy Grail War.

Hours before the summoning of the last servant-

The red-clad Archer and blue-clad Lancer were exchanging blows with one another, the former forming and shattering countless weapons upon the latter's red demon spear. Their Masters were fighting one another within the confines of the building, the Archer's barely able to keep ahead of the Lancer's through the knowledge of the building's layout. The servants stopped suddenly when the presence of the boy known as Shirou appeared, right hand upon the katana's handle and eyes half-lidded, a bone sword slightly lower than the katana also at his waist.

The Masters arrived right as the Lancer charged the boy, both pairs of eyes widening at the realization of who was fighting. "Lancer stop!" The Hound of Ulster did not hear his Master's words and the fear tinting them, crossing the distance within the blink of an eye. Time seemed to slow as the spear was thrust forward, the Lancer's eyes widening as Shirou dodged the cursed spear, letting out a small gasp as the sheathed blade hit him in the chest. A kick then came right behind the blade, sending the Lancer skidding back to where Archer was.

"Can you provide me with a challenge?" The Archer narrowed his eyes, charging alongside his enemy to kill the bystander, not heeding the words of his Master as well. The spear Gáe Bolg was parried to the side, Kanshou and Bakuya clashed with the sheathed blade briefly before a single slash broke the two and sent Archer back a few meters. Another pair formed in the Unnamed Hero's hands, causing Shirou to narrow his eyes slightly at the sight, calmly deflecting the strikes from both Servants.

Shirou retreated under the assault of the two Servants, disappearing and reappearing back several yards with one hand gripping the sheathe and the other gripping the handle of the katana. The sword was released from its sheathe by a margin, the Lancer and Archer both holding their weapons defensively, while both Masters ducked down, having witnessed or heard of the event once before. With the ring of steel on the sheathe and breaking of metal the sword was drawn and broken, shattering into pieces of metal.

Nothing happened for a moment, the Lancer shifted away from his defense and was rewarded for it. Where the Archer skidded back from the middle of the field to kneel beside the Masters, both weapons broken upon impact from the invisible force, the Lancer went flying into the building and out the other side and kept flying through building after building. The building shifted, then collapsed upon the line the slash made by the Ancestor Killer.

The Lancer's Master heard her Servant over the mental link, concerned but otherwise relieved that he was still talking, 'God damn that hurt. I really was not expecting a blow that strong.' The Irishman fell silent as he made his way back, while the Archer and his Master stared somewhat dumbstruck at the visage of the red-haired teen, bored look in place as a simple katana formed in his hands similar to Archer's swords. The katana was sheathed and the boy left with a sigh. "I hope there is someone in this War that can hold a candle to an Ancestor, even the idiot Ancestor knew better than to lower his guard against a magus."

And with that Shirou was gone, the two Masters getting up and parting ways without a single glance at one another, very aware of how close to death both had come. They both stopped as the same thought came to mind, 'What kind of Hero did/will he summon?' They both noticeably shuddered at the very thought of what that entailed, they made plans not to win now, but to simply survive.

1 minute before start of War-

The summoning circles were prepared, mercury in place of blood, their practioners waiting patiently, their father standing behind them with an unlit cigarette in his mouth. They spoke the chant, one voice full of childish mirth, the other filled with cold apathy. A flash of white light and bits of smoke invaded their vision, obscuring their Servants from view. Red markings appeared on their hands, a sword vaguely in the shape of a katana crossing over the unused middle seal from the last war, one line being the blade, another the back, and the finally one being the handle and guard. Ilya's was much more elaborate, a crown with lines of 'light' above it and an expanse of 'shadow' below it.

A child's giggle greeted them first, then a young boy's body leapt out of the smoke in front of the girl. Unprepared, she was tackled to the ground with a hug, while the other three occupants merely stared at the scene. The Servant was up moments before the girl opened her mouth, shadowed face grinning wildly at the girl with a Cheshire-like smile. The girl got up with a huff of slight annoyance, looking over the Servant she summoned.

The first thought was white, almost everything noticeable about the Servant was white, a hoodie, pants, boots and gloves all the absence of color. A hint of yellow lay within the shadowed confines of the hood, though whether those were eyes or hair remained to be seen. The only none-white object the child held was a black sheathe holding a katana with black tape around the handle. Only Shirou noted something about the boy's shadow, it did not fully match the boy's description with the single light.

He turned to face his Servant, almost completely his clone if it weren't for the Servant having his katana on the right hip and green eyes boring into his golden ones. A simple white kimono with brown triangles at the end of the sleeves and the bottom of the cloth, a blue sash around his waist into which a katana was sheathed, a sword-shaped bone slung to rest at the left shoulder, and two gold earrings on the right ear. The Servant held the exact same expression as Shirou did, making the resemblance all the more uncanny.

The child introduced himself first, speaking with child-like glee and a fast pace. "Hi, I'm Berserker, are you my master?" Ilya nodded her head slowly, still trying to comprehend her servant in relatable terms and failing. The child turned around, the smile growing slightly wider on spotting the other Servant, disappearing and appearing clutching the unnamed Servant, nuzzling the man as he did. "Nii-san! Saber Nii-san! You're here! Can we play in a bit, I want to play! Can we play, can we?" The last part was directed at both Masters, one dumbstruck at her Servant, while the other merely shrugged.

Kiritsugu blinked several times before sighing and leaving with a slightly wistful smile, remembering his short experiences ten years ago with what he assumed was the same being. He immediately frowned upon remembering the ability of many amongst the 4th War, if summoning the Child-King meant that a similar or worse war was on the way… It was best not to dwell upon such things, hopefully his children would not be amongst the dead of this war, even if the amount of deaths in the previous were below two dozen, collaterals included.

AN: Here is the summary of events,

-Shirou is raised alongside Ilya by Kiritsugu. Shirou does not want to become a hero, being influenced by his time in the 4th war to merely wish to fight. He trains secretly until Kiritsugu takes notice and helps him, alongside several others such as Waver.

-He has killed three Ancestors, all pitiful and merely placeholders, and has a thirst for bettering himself and fighting strong foes. At his current level he is just slightly under Lorelei if he were to go all out, though he prefers to toy around with stronger opponents. During the last two years he has taken to traveling and killing Dead Apostles and Rouge Magi.

-Shirou did not go through School due to him being even more messed up than regular from being a participant in the 4th war, instead being home-schooled by Kiritsugu.

-Sakura is raised by Kariya away from Zouken, traveling with him throughout Japan and occasionally outside of it. She took up drawing and painting much like her Servant during the 4th war and remained good friends with Shirou after the war up to the beginning of the 5th war. She has self-taught herself the basic Magecraft techniques, and been instructed in reinforcement by Shirou when they are both in Fuyuki.

-Caren Hortensia is the Mediator of the 5th war alongside being a Master after her Father and Grandfather passed away. She is friends with Shirou and Sakura, who helped her get settled within Fuyuki during her first few weeks there.

-Due to Remnant taking the Curses of Angra Mainyu, Kiritsugu is not cursed and is alive to the 5th war.

There will be 15 Servants within this War, two of every base class, along with a single Ruler. Note that I'm not limiting myself to only Fate/stay night and my children for this one, there will be Servants from other Fate works involved.

Edit: As of 2/19/15 I have included several of the non-canon summonings to the prologue, If they are canon of any Fate work, I will not be going over them.

Edit: As of 8/17/15 I have included one last non-canon summoning to the prologue.
