Prologue

XXXXXXXXXXXXXXXCXXXXXXXXXXXXXXXXXXXX

It had been two years since Kiritsugu adopted shirou, and they had adjusted to a life of quiet normalcy. Or as normal as it could get in that household.

"Dad, please teach me magecraft." A 9 year old Shirou Emiya asked his adopted father.

"No" the man responded, not even looking up from his newspaper.

"Why not?" Shirou asked, frustrated.

"Shirou," Kiritsugu started, putting the newspaper down, "Magi walk with death. I don't want you to end up killing yourself. And with a crappy teacher like me that's probably twice as possible." He half muttered the last part.

"But dad I-" He was cut off by the ringing of the door bell.

"Shirou, could you please get that." The black haired man said.

Shirou sighed. "Fine, but this isn't over." With that he stood up and walked to the door. He opened the door and spoke. "Hello, is there anything I can do for-" He didn't finish his sentence on a count of his confusion on exactly what he was seeing. In front of him stood three men. And he could see at least a dozen other various men and women standing in the yard, as if waiting for something.

But what confused him wasn't the number of people, it was their appearance. They all has white hair bone white hair and blood red eyes. The man standing in the front was the most unique. While all of the the other men and women looked identical, this man had a different face and body type. Adding to his different look was the hair and beard on his face. He exuded an uria of nobility that made shirou feel somewhat annoyed for some reason.

"It is rude to stare boy" The man spoke. Depot the strong look he had, his voice reminded shirou of Raiga Fujimura's, but older.

"Oh sorry," Shirou apologized, "Is there anything that I can do for?"

"Hmm," the man stared at Shirou inquisitively before speaking again. "Well, it seems that he managed to teach you some manners. My name is Jubstacheit von Einzbern. My companions and I would like to speak with your father, Kiritsugu Emiya." He spoke calmly, but Shirou could tell he was irritated at something, he had no idea what though.

He turned his head back into the house. "Dad, it's for you." He said, making sure he was lots enough to be heard.

He heard Kiritsugu get up and saw him as he walked over to the door. "Hellow, how can I he-" as soon as he saw the people at the door, Kiritsugu pushed shirou behind him and reached inside his kimono to grab his - always on hand - Thompson Contender.

Before he could say a word, the man, Jubstacheit, spoke. "Call yourself Magus Killer. We have no intention of starting a fight. Yet. That bounded field around your house should assure you of that. And even if we were do you honestly think that you could kill us all, especially in that weakened state you're in?" At his word all of the people standing around the yard suddenly turned towards the door and seemed to reach to reach for objects that Shirou evidently couldn't see. "No, I am many things Emiya, but blind I am not. You wouldn't destroy the grail without some sort of reason. Now I want to know. What is the reason?"

Kiritsugu studied the man a bit longer before slowly taking his hand out of his kimono. "Shirou, please prepare some tea.

Shirou just stood there.

"It's alright, go ahead." Finally shirou walked back into the house, but not before sending one more questioning glance to the door. Kiritsugu turned back to the Einzbern. "Well Acht, if you're wondering why I destroyed the grail….you can really blame yourself.

Jubstacheit took a sip up tea as he sat across from Kiritsugu in the dining room. The tea, while not as good as his Darjeeling back home, was decent. He took another sip before speaking. "So let me see if I understand correctly. The avenger that we summoned during the third war hid itself inside of the grail after it was killed. It then went on to posses the grail and corrupt it. Now any wish made by the the grail will result in the genocide of humanity."

"You don't seem very surprised." The Magus Killer noticed.

"Well, I would be lying if I said a small part of me wasn't curious to why avenger lost so easily." The Golem stated. "It was suppose to be a dark god after all."

"I see," The older Emiya said, "so what now?"

Jubstacheit said nothing for a minute before turning to one one the Homunculi in the room. "Gather all of the Emiya's possessions. They will be returning with us back to Germany."

"I forgot how cold it was here." Kiritsugu said as he, Shirou, Jubstacheit and the homunculi sat in the limousine as it drove through the snow.

"How do you even know where you're going? All I see are snow and dead trees." Shirou spoke while wrapping his arms around himself to try and stay warm.

"Don't worry." Kiritsugu said, "We're almost there." As if on cue the shirou could see a large castle like mansion through the window. They stopped and got out of the limo. The homunculi handled the bags.

"Come" Jubstacheit said as he walked up the stairs. The Emiya follows him. As they entered the mansion Jubstacheit walked up to a homunculus that was sweeping the floors and ordered. "Bring young Illyasviel here immediately." Without a word the homunculus bowed and walked further into the building. The golem turned around before speaking to the father and son pair. "Kiritsugu Emiya, you will be staying in your previous room. I will arrange a room for the boy to sleep in later."

"Master Jubstacheit," a voice sounded from the maid who had managed to return to the room unnoticed. "I have retrieved Mistress Illyasviel."

Next to the maid was a small girl with long white hair and shining red eyes. She was wearing a purple dress with a matching hat. Her eyes were wide, with tears threatening to fall from them. She uttered only one word. "Papa?"

"Illya" the Older Emiya said, tears coming to his eyes as well. He quickly dropped the suitcase in his hands and ran towards her. She ran to him in turn and when they met, the hug each other while the tears finally escaped from them and fell down their faces.

"Papa! Papa! Papa! I thought-I thought!" Ilya cried, not being able to finish her sentence due to the tears.

"I know. I'm sorry." Kiritsugu said over and over was stunned. His father was normally a pretty passive person. He had been told about his sister Ilya before coming here, so he knew to expect something big. But this was the most emotion that his dad had ever shown in front of him, even more then when he saved Shirou from the fire. Maybe THIS was the happiness he was looking for. Maybe there was more to life than helping people. I mean, what was the point of helping strangers if you never had anyone to go back to. He couldn't resist to urge to smile.

After a few more minutes of passionate tears falling, the father and daughter ended their hug. Ilya looked over her father's shoulder and saw Shirou. Not knowing what to do, he smiled and waved. She turned back to her father. "Papa," She started, "who's that?" She asked as she pointed at Shirou.

"Oh," Kiritsugu said apparently having just remembered the red head's presence, "that is your new brother, Shirou. I adopted him awhile ago." At his words her eyes widened. She walked up to the golden eyed boy and looked at him similar to how a doctor looks at a patient. Suddenly white haired girl jumped up and hugged the confused boy. "That's great. I always wanted an Onii-chan."

Kiritsugu chuckled lightheartedly at this. "Actually, Illya Shirou is about a year younger than you."

Shirou turned the the smaller girl who was still hugging him and smiled happily. "Nice to meet you Nee-san."

Ilya quickly responded. "Nice to meet you Onii-chan.

This story is Shirou x harem, but mainly Shirou x Ilya

When the Grail war hits it is going to be similar to fate/apocrypha. 2 teams. 14 masters. 14 servants.

There will also be some MAJOR changes from Fate/Zero, but those won't be relevant for a while.
