Hey everybody! My muse had finally come back from the dead! It feels great to be writing again but my creative juice is not flowing as easily as I want yet, so this story will not be updated very quickly. This story will not be as dark as the Fate series since I'm horrid at writing such a genre.

Shirou (suddenly appearing in the room): Hey! What's going on here! Where am I?

Ryuga: Ahh, good. You're here.

Shirou: Ehh? Who are you?

Ryuga (chuckles evilly): Just a demented author with Zelretch's sense of humor. Now... Invoke Reality Marble! Nirvana's Inferno: Taint of the Benevolent God!

Shirou: WHAT! (before being sucked into a dark portal)

Ryuga: Now that that's done, on with the story!

(Sorry bout that little crack-tastic Author's corner there.)

Illya: Shiratori Ryuga does not own Fate/Stay Night or Campione. He could barely write fanfics as it is.

*Prologue*

"I'm sorry, onii-chan." The voice of a young girl echoed the vast field of plain whiteness. "I wish I could send you back, but it is impossible."

In front of the collapsed broken body of a redhead stood a beautiful white-haired girl in an elaborate outfit known as the Dress of Heaven. Behind her stood an older looking version of the girl and a man in a black suit with a dark grey duster. While the redhead was not cognizant of his current situation, the image was burned into his mind. The serene smile of the older woman and the proud smirk on the man's face did wonders for the broken psyche of the young man.

"With the gates leading to Heaven's Feel closed, I cannot send you back to our world." The young girl continued; a sad smile on the childish face that the young man wished he wouldn't see. To him, it looked out of place.

Slowly, the young man forced his right arm up and patted the girl on her head. He felt his limb burned with intense agony, but he forced down the grimace. "It's alright, Illya," he sighed softly as he forced a smile on his face as the pain that was destroying his cognitive ability was slowly becoming more tolerable. "If I didn't do what I did, there wouldn't be a world left back there."

He had forsaken his ideals to save the girl he had sworn to protect, had walked away from the path his father-figure had once took, and he didn't regret. He felt sad about leaving the girl and her sister behind and his inability to hold onto the promise made with the purple-haired girl, but there was nothing else he could do. It was either pushing his body to the breaking point or watching the entire world be destroyed by the tainted source of all evil in the world. To him, a man who had once sought the path to become a hero, there was only one choice to make.

"While I can't send you back to our world," the little girl suddenly spoke up, "I could send you to another world. Maybe we can start over and be like the family we were meant to be."

Before the young man could even voice a single syllable, the girl had pulled him off the ground with ridiculous strength and started dragging him away from the two adults. Not able to do anything since his body was still in pain, he simply went with the girl's whim. Looking back, he saw the two adults waving at them.

"I'm proud of you, Shirou," the older man finally spoke up while the woman who looked like a grownup Illyasviel continued to wave them off. "Remember, there will always be something more important to a hero than saving the most lives in a given situation. Take good care of Illya and have a happy life."

Shirou jolted awake as the plane he was on landed at its destination. Rubbing his eyes tiredly, he stretched his arms up to loosen any kinks from the fifteen hour flight. Shaking the tiredness out of his head, he gave a soft sigh. 'It's been a while since I had that dream,' the redhead thought as the plane came to a complete stop at its terminal.

It had been ten years since his soul had been sent to this universe with the help of his younger-looking older sister. When they first arrived, his soul was inserted this world's version of Shirou, who at the time was in a coma due to his family being caught up in a terrorist bombing. He was then adopted by a man named Francis D. Stein, who was ironically going by the name Emiya Kiritsugu at the time.

Shirou stiffened a laugh as he thought about that little revelation when he neared the airport's immigration. The coincidence was quite ridiculous from Shirou's perspective. What was more ironic was the fact this world's Kiritsugu was also the blood-related father of one Illyasviel. While she carried the Stein's family name, she appeared to have inherited her mother's appearance.

According to Kiritsugu, or Francis since Shirou didn't see him as the Hero of Justice that had raised him in his original world, the woman was someone he had met in Moscow a few years ago. Apparently, she had died due to cardiomyopathy. Illya, whose soul also came to this world with Shirou, had told him how broken a man Francis had become at the time and threw himself into research at Lomonosov University, where he was teaching at the time.

A year after the death of Francis' wife, he decided to move to Japan with his five-year-old daughter. Apparently he was invited over by his friend and colleague Kusanagi Ichirou, who was also friend with Shirou's real parents apparently.

After the death of Shirou's parents in this world, Ichirou had tried to take care of him, but with his two grandchildren and a being retired, he wouldn't be able to take care of another child. Thankfully, Francis, who had at the time left everything behind in Moscow including his original name, had decided take him in.

Shirou had tried asking why the man had changed his name, but Francis never did answered.

Interestingly enough, with the money his foster father had after selling most of his assets in Russia, he was somehow able to procure a mansion similar to the one he had lived at back in Fuyuki. He still had no idea how it was possible to get a large place like this in Tokyo, but he decided not to ask seeing how secretive this world's Francis was. At least the tool shed of the mansion served its purpose for being his and Illya's personal workshop.

Having a better understanding of his personal brand of magecraft from fully assimilating Archer's memories and knowledge had given him all the basics he had missed out in the Magus Killer's mediocre lessons. With a younger body, his nervous system had not been damaged from channeling prana yet. This allowed him to work on his magecraft without the dangerous and stupid method he was working on back in his original world.

Speaking of his original world, the teenager-turned-preschooler had wanted to go back to his world. He had practically begged Illya to tell him any methods she could think of, but she answered negatively. Apparently, the Third Magic had shut itself off to that world before the ex-homunculus could send him back, so it was a one-way trip. The only way she could let her 'onii-chan' continue living was anchoring his soul to another reality. It was more or less creating the phenomenon of the Kaleidoscope through Heaven's Feel, and she had little control over the process. It explained why Illya's soul arrived to this plane about six years earlier than his did. The only way he could even have a chance to return to his original world was for him to somehow learn the Magic known as Kaleidoscope, pinpoint where his world was in the sea of realities, and transport himself there without being thrown off course. He would probably have better luck winning the lottery over a hundred times in a row than something like that happening.

Well, he could always try and find Zelretch, if the enigmatic Old Man of the Jewels was to come into this dimension. This idea was instantly discarded by Illya due to the stories she had heard about the man. Meeting a guy who would most likely throw you into a world that will make you lose a part of your sanity is and forever will be a very, VERY bad idea. With no other choice, Shirou decided to merely settle down into the new life he was probably going to be stuck with.

Well, at least this world wasn't too bad. Apparently, magecraft was more powerful here. The interference from Gaia was either, surprisingly, nonexistent or it was so miniscule it might as well be completely absent. Unfortunately, the cost to trace any Noble Phantasms had nearly tripled. The weapons pulled from his Reality Marble would not disappear, but even bringing out Kanshou and Bakuya would leave him winded for a while. At least with the same amount he could pull off a fifty-sword rain so it wasn't too bad.

Maybe it was his inexperience or the different workings of the world, but he had decided to simply trace as many weapons as he could fit into the toolshed behind the house so he would be able to just pick one up if he ever needs to.

On another note, his hair wasn't even showing the first sign of turning white from overusing Projection, which was another plus for him. His red hair made him stand out as it currently is. He didn't want to think how much attention he would grab if his hair was going white.

Apart from tracing, he was also working on a motorcycle that runs completely on runes instead of gasoline. He had thought of starting such a project on a washing machine but scrapped the idea after Illya had laughed at the ridiculousness of such an idea. He had mumbled about how awesome such an idea truly was and his older sister simply couldn't see the greatness of it when he happened to spot a 1985 V-Max. It was something Francis had kept for sentimental reasons but the thing was falling apart. And so, the young boy took this opportunity to try and fix up the old piece of junk through magecraft even though he was still too young to ride it.

Surprisingly, he had somehow succeeded in such a feat in eight years, and decided to rub it in Illya's face for doubting him. She simply responded by weaving a ridiculously large hawk out of barb razor wire through her alchemy and sent it at him. Thankfully Francis had been away due to a special lecture he was giving at Tokyo University, but he was forced to run away screaming like a little girl for three hours. He didn't regret his actions one bit though and would continue to mock the white-haired girl from time to time, causing her to either pout cutely or snap at him with some kind of wire construct when Francis' away.

Shirou had been utterly surprised at the time when his sister first utilized her magecraft. According to her, it was the specialty of the Einzberns, which was alchemy. It was an interesting lecture from his younger-looking older sister that was for sure. She had apparently perfect a way to fly through the use of her wire-woven puppets as well, where she would create small sets of wings that protrude from different parts of her body. How she could even do something like that was still a mystery to the redhead but he just chalked that one up to something he would most likely never understand or Illya will tell him eventually. After all, it wasn't like there's anything they really need to hide from each other unless they simply wanted to see the other squirm in frustration.

Stepping out of the airport with the duffel bag he had packed for the trip, Shirou couldn't help but grin at the beautiful scenery in front of him.

Unfortunately for Shirou, this trip is but the first step into his new and very chaotic life.

*Author's note*

Hi everybody! Shiratori Ryuga here! After a long break from writing fanfics, I'm back. I was hoping I was the first to have a Campione and Fate/Stay Night crossover story but I got beat to it... Oh well.

First thing on the agenda...I need a beta. My beta had quit on me a long time ago so my grammar will most likely be shoddy. I'll also need someone who knows how to type Renaissance style English seeing that's how the gods in Campione speaks. It's all just for fun anyway.

Second, I know I will (if I haven't yet) butcher a few Nasuverse laws of magecraft, like Heaven's Feel closing after Shirou Excaliblasted the Grail, but it's all plot background. More or less Shirou's soul arrived in the Campione world with everything that had been etched onto his body, i.e. Archer's arm, Avalon, the circuits system that is not native to the world of Campione. Same thing with our favorite loli.

For the Reality Marble thing in the Author's corner at the beginning: Well, if Urobuchi Gen's Reality Marble (Dead End Catharsis: Heaven and Hell Drop) decreases happiness of all character by one rank, mine would be the opposite, which targets one person and raises the happiness by one rank. Unfortunately, it would also raises the the rank of said person's chick magnet skill (which doesn't work on Shirou since his BAR is already rank EX), and with Shirou's denseness regarding such thing...

Well, that's all for now. I can't think of anything else to address so feel free to comment and critique (just don't flame me please).

Till next time.
