AN: Alright, this is my first FanFic to let you all know. Constructive Criticism for my writing would be greatly appreciated and welcomed. Flamers, your reviews will be read and almost entirely ignored while taking useful criticisms that are, if at all, present. Shirou will be OOC as he will be inheriting parts of both his parents' personalities. Thank you all and I hope you enjoy.

Disclaimer: I don't own Fate Stay/Night or Fairy Tail, if I did they'd be plotted differently and probably suck.

Prologue: First Occurrence

Eight years before the Holy Grail War:

After a year of constant pestering:

"Dad could you please teach me how to use Magecraft?" Shirou questioned.

"No," replied Kiritsugu, "it's too dangerous for you."

"But Dad, I really want to learn so I can help others!" Shirou replied enthusiastically.

"Alright fine, if only to stop your constant questioning Shirou." Kiritsugu replied with a sigh.

"Thanks Dad! I won't disappoint you." Shirou replied, beaming at his Foster Father.

"Alright now each magus has an Element and an Origin, some have two of one or both but their rarer than normal magi. These Elements mostly relate to the five primary elements: Fire, Water, Earth, Air, and Ether. Origin's vary between people ranging from vanity to wind to even lust." Kiritsugu replied as he began to lecture Shirou before starting on the basics of Magecraft.

Three Hours Later:

"That's, extremely painful Dad," Shirou panted, "are you sure I'm creating my circuits right?"

Kiritsugu paused in his reading, using old clan books to help him teach Shirou, and questioned "Creating?"

"Yeah, isn't that what you were trying to get me to do?" Shirou replied in confusion.

Kiritsugu maintained his calm façade even as he panicked inwardly and calmly replied "Shirou, the goal of this exercise is for you to activate and use your natural circuits not create new circuits."

Shirou sighed, "Alright Dad, how do I do that?"

Timeskip – Next day, afternoon after many training sessions:

"Alright let's try this again Shirou, activate your natural circuits and try to reinforce this chair and then this knife." Kiritsugu said to Shirou.

"You got it Dad." Shirou replied as he set to work.

As Kiritsugu watched on he noticed a spark of fire come from both Shirou's skin and mouth as it had for the last couple training sessions since Shirou accessed his 27 Master-Quality circuits. This both concerned and intrigued him as he had never hear or seen this before.

"Alright Dad I'm done." Shirou spoke up startling Kiritsugu from his thoughts.

"Alright Shirou let me see them so I can see your work." Kiritsugu replied.

Kiritsugu used Structural Analysis on the chair noticing the shaky and nearly useless reinforcement on the wood and sighed saying "The chair is a near failure, strong enough to stop a thug with a sword but useless against anyone with more strength and skill."

"Alright dad, may I see the chair so I can analyze it and possibly figure out where I went wrong?" Shirou sheepishly replied.

"Sure, here you go." Kiritsugu replied as he analyzed the knife and almost expressed his shock vocally, though his jaw still dropped as his eyes widened, as he noticed the perfect reinforcement which bordered on Absolute reinforcement.

"What's wrong Dad?" Shirou questioned worried at the look of shock on his Father's face.

"Shirou, the reinforcement you performed on this knife borderline absolute reinforcement, which is reinforcing the molecules that compose an item as well as the item itself, even though your reinforcement on the chair nearly destroyed the chair." Kiritsugu replied with great emphasis as he tried to regain his composure.

Shirou blinked in shock and wondered why this happened when he did the same procedure on both and a figurative lightbulb lit up in his head, "Dad, could it relate to the Element Origin pairs you mentioned yesterday?"

Kiritsugu pondered this idea and replied "You could be right there Shirou, judging from the exercise just now I'd say your Element and maybe your Origin revolve around blades, though I have cause to believe fire, flames or maybe dragons are related to your Element and Origin."

Shirou blinked in shock and questioned, "Why is that dad?"

Kiritsugu sighed and commented "I'll tell you later, let me see about finding a way to determine someone's Element and Origin."

Shirou nodded but asked curiously, "Say Dad, what's your Element and Origin?"

Kiritsugu replied calmly, "My Origin is a dual set of Severing and Binding and my Element is a dual set of Fire and Earth."

Six Years before the Holy Grail War:

Kiritsugu was in pain due to another onset of a coughing fit causing Shirou to panic. "I'm alright Shirou, having what was left of my Emiya Family Crest implanted into you sped up the Curse I 'won' from the last Holy Grail War." Kiritsugu replied in an attempt to console Shirou

"Can't I do something dad?" Shirou questioned.

"Yes, you can focus on tracing the weapons I showed you through my memories of the fourth holy grail war as well as the other weapons, some of which I have no idea how you even got the projection blueprints of." Kiritsugu replied, chuckling at the end.

"I told you dad, they just came to me." Shirou replied indignantly.

"Calm down Shirou, what's the current strongest you can 'Trace' at the moment?" Kiritsugu questioned Shirou.

"My strongest is tied between Avalon, God Force: The Five Warriors of the War God, Kazikli Bey: The Fortress of Impalement, and Nine Lives: The Shooting Hundred Heads." Shirou replied calmly, reciting the names of the Noble Phantasms.

"Good, now focus on Gram, Gate of Babylon, Excalibur, Gae Bolg, Gae Dearg, Gae Buidhe, and God Hand Shirou, I want you to be able to perfectly trace all of these and be able to use them all in a row before I pass away." Kiritsugu commented/commanded Shirou.

"You've got it Dad! Oh, and don't talk about that please." Shirou Beamingly replied and requested.

The day of Kiritsugu Emiya's Death, five years before the outbreak of the Fifth Holy Grail War:

Kiritsugu sighed as he felt his heart slowing and his muscles relaxing "Heh, I guess it's time for me to 'kick the bucket' as they say in America now." He turned and faced Shirou, "Shirou, no, Son – take up my dream and alter it to become yours, protect your friends and those whom you consider family. Ehehe, I wish I had the courage to drop my ideals and fight for my family and friends, I hope and pray that you do have that courage son."

Shirou cried but kept his voice steady as he spoke to his father, "Alright Dad, wait for me and I'll come to you if I can after I 'kick the bucket' myself and I'll alter your ideals until they fit me perfectly so I can make you proud."

Kiritsugu smiled melancholically and said "You've already made me very proud Son." Shirou gasped and beamed at his Father and held his father's hand until he head the rattle coming from his father's throat as Kiritsugu's hand loosened and then just held his father's hand and cried until he felt emotionally stable and then got up to get the phone and call the morgue asking them to prepare a tomb.

AN: Well that's the prologue of what happened before the story truly began as well as a few hints to the Oddities Kiritsugu noticed in Shirou's Magecraft. I hope you enjoyed and I hope to get the next chapter out within the week
