I think keep all that Canon is what would be the most fun to read. But feel free to change things to fit Kirutsugu more. :)

What do you think of him having the Emiya Crest? (Along with Innate Time Control, of course!)

Wouldn't he have to inherit that from Kirutsugu first? Don't think/expect it to happen before he finds out about the biological connection. Speaking of which, you could have some other character mentioning something about "fate" or "prophesy". After the first, Kirutsugu didn't just save any random person - it had to be his biological son.

Yeah, but I did promise you that I would have Kiritsugu find out, and not die ignorant, so I deliver. As for comments on 'fate', we'll see.


Kiritsugu and Shirou were speaking. The older male said, “Shirou, tell me. Do you remember anyone from your previous life? Anyone at all? This is important,” seriousness radiating from him.

The eight-year-old Shirou started. He reluctantly said, “it’s painful to even think of them. I had a mother but no father, I think.”


Shirou kept trying to remember. He said, “I remember a redhead with blue eyes. Ao- something? I remember thinking her appearance strange, because she didn’t grow older.” Kiritsugu forgotten, the boy kept speaking. Shirou said, “she must have been my mother. I remember asking her about my father, and she said that he was a hero and a killer. How can someone be both, though?”

A strange noise escaped Kiritsugu, bringing Shirou back to reality. A new question entered Shirou’s mind: what was that ‘meep’ noise the old man made just now?

Kiritsugu ruffled up Shirou’s hair and said, “all right, Shirou. That’s enough - I can see remembering has strained you. We can revisit this topic some other time, all right?” Though he seemed more strained himself, somehow.

“Okay!” Shirou said, ignoring the strangeness of his father’s behavior. ‘I must have imagined things,’ he thought.


Kiritsugu was on an outing with Raiga, but not to talk business. He simply wanted someone to drown his sorrows -or, rather, the insanity that surrounded his life, this time- with.

After an indeterminate amount of time, Raiga’s booming voice echoed, saying, “all right, Kiritsugu. Out with it.”

Kiritsugu started, looking at the older man in surprise. Still, he said, “What do you mean?” Stubbornly setting his jaw.

“Kiritsugu,” Raiga said, an impish smirk on his face, “my life has depended on my observation skills more than once. I’ve also raised a daughter who was much more stubborn in her teenage years than you are now, I assure you. You’ve met her daughter; imagine Taiga with a more serious personality and multiply the stubbornness by a factor of three, and you’ve got Saiga. You aren’t going to manage to fool me or overcome my patience, so don’t even try.”

Kiritsugu sighed. He seldom could get anything past the irritating old Mafioso. Still, should he- oh, to hell with it; though it might be the alcohol talking. He said, “Shirou remembered his biological mother.”

Raiga raised an eyebrow, indicating that he knew there was more to the story.

Kiritsugu sighed, then kept speaking. He said, “the thing is, I had met his mother before. As a one-night-stand.”

“I see,” Raiga said, though Kiritsugu doubted he truly saw.

“I got him to take a DNA test, and it’s a match. With me. It turns out that I’m not his adoptive father, but his actual dad,” Kiritsugu said, hiccupping a bit; realizing that he had had enough whiskey, he put the glass down.

Raiga studied him for a bit, then said, “Kiritsugu, do his origins actually change anything between the two of you?”

Kiritsugu thought for a moment, then said, “hnn,” not sure himself of what he meant by that grunt. Then, he suddenly devolved into an anger-filled monologue. He said, "what I don't understand is why she never told me. Fuck! What the hell was she thinking?! She's too irresponsible to raise a child on her own! That woman.... I was father to a second child, and she didn't even see it fit to tell me!"

Raiga ignored Kiritsugu's rant, put down his glass and did not touch the bottle of whiskey from that moment on, complaining in a low voice that whiskey did not agree with him, and that he much preferred sake to that foreign crap.

It only made Kiritsugu giggle, but he ended up breaking out sobbing immediately afterwards.

The next morning (afternoon, really), the horrible headache and the dryness of his tongue belied the fact that Kiritsugu, in fact, felt better than before. 'That Raiga,' he thought, 'he was a real help, I've got to admit. Conniving old man, he got a promise to give him one of my rarer guns out of me, too.'


Shirou had just asked Kiritsugu to teach him Magecraft, for the umpteenth time.

“All right,” Kiritsugu said.

Shirou was about to ask him why not, when what Kiritsugu said registered. He said, “wa- wait, what?” Surprised to the point of stuttering.

“I said ‘all right’, Shirou,” Kiritsugu said, smiling for the first time in Shirou’s memory, other than that day, “would you rather look a gift horse in the mouth, or shall we start with the training?”

The ‘yeah! Let’s go!’ Shirou let out was deafening.

The first thing Kiritsugu taught him was how to open his Circuits and about the 'Switch' and ‘Trigger’, as he called them. 'The Switch is a concept that allows one to turn their Circuits on and off. Not everyone can manage it at all, even if they have Circuits; some can only do so imperfectly, and activate their Circuits only when they are angry, or aroused, or something else. The Trigger is an 'image' you 'picture' in your mind, preferably with more than one sense - as in, if it's a bee stinging you, you remember the pain, the sound of the buzzing AND its looks. Choose the image wisely; it has to be something you wouldn't normally do.'

Those were Kiritsugu's words.

Shirou saw his father’s certainty that Shirou had Circuits as strange, because in the past, one of the man’s arguments against teaching him Magecraft was that ‘most people have no Circuits’, but the boy ignored that as unimportant.

Meditation was a strange way to start learning the mystic arts, but if his father said that it was important for learning Magecraft, who was Shirou to argue?

It took a few weeks, during which Kiritsugu started Shirou on firearms training (a disaster); then, when that failed, Kyudo (the Way of the Bow), for Shirou to realize what meditation was all about. When he did, he was a natural, according to Kiritsugu. Shirou simply made himself enter the same state of mind he did for Kyudo whenever he meditated.

It only took Shirou a few days after that to find his Trigger (the hammer of a gun hitting the bullet; he would never again try shooting a gun, so it was a safe choice), and he ended up discovering twenty-seven Circuits of slightly above average Quality for his age; or so they both thought, at least.

The first spell Shirou was taught was the Structural Analysis. After Kiritsugu made sure that there would be no accidents with it, he disappeared… somewhere.

Shirou was often lonely, despite that freeloader’s ‘pleasant’ company, so his refuges were books (mundane or otherwise) and Magecraft training. That continued until a confrontation he had with the Tiger.

“Ne, Shirou-chan! Why don’t you like your neechan?!” Taiga shouted childishly.

“You’re a freeloader, you’re annoying, selfish, childish, violent… do I need to say more?” Shirou said, annoyed at her even more.

“I see,” Taiga said, strangely serious. Then, she said, “but is any of those the reason you push me away?”

Shirou straightened up, all of a sudden. This new Taiga was creeping him out. He said, “what do you mean?” And if his voice quivered a bit, he doubted Taiga would catch on.

The sixteen-year-old smiled knowingly and said, “I mean that you seem to be under the impression you don’t deserve to have any friends, Shirou. What you are doing is called ‘moping’, and it’s not much better than the ‘creepy emotionless kid’ thing you had going last year.

“I-” Shirou said, cutting himself off. He tried again, only to stutter once again.

“Think about it,” Taiga said and patted Shirou on the back, leaving him alone with his thoughts.

That night in his room, Shirou had a hard time falling asleep (and he didn’t even stay in the shed, despite Kiritsugu not being there to remind him. He turned in early). He could only think of Taiga’s words, and whether she was right about him moping and pushing people away.


By the time Kiritsugu was back, a few months later, Shirou had improved his Structural Analysis to a frightening degree. His reserve of Od was suspiciously slow to run out, as his father put it, which was why he was able to improve so quickly. Unfortunately, he was no closer to having an answer to Taiga’s words.

He no longer saw the older girl as a freeloader though; in those few months, Shirou came to view Taiga as family; an annoying, somewhat violent older sister.

Kiritsugu took Shirou aside for a talk which was ‘the opposite of what an adoptive child usually hears from their parent’, whatever that meant.

“What do you mean, old man?” Shirou voiced out loud.

“Well, Shirou - I once knew your mother, so I had you give your blood that one time for a DNA test… and I’m your actual father,” Kiritsugu said, a strange look on his face.

Shirou processed the words, blinked a few times and said, “that does explain why you reacted in a weird way when I told you about my mother,” not bothered at all by the information.

Shirou also took in Kiritsugu’s features; the two of them had similar jaw lines and a similar eye color, though the man’s irises were a very deep brown, while Shirou’s were more of a golden brown. Otherwise, Shirou took after his mother, though he had auburn hair whereas his mother had bright red, from what he remembered.

Kiritsugu relaxed a bit, saying, “I’m glad you took this so well. I thought you might be angry.”

Shirou was puzzled. He said, “why would I be angry? Mom didn’t even tell you about me, right? So I don’t blame you for not being around before - and you’re around now, aren’t you? There’s something I was curious about, though.”

“What is it?” Kiritsugu asked.

“What did my mother mean when she called you a hero and a killer?” Shirou said, making Kiritsugu’s shoulders slump.

The man sighed and said, “that’s a talk for another time,” effectively killing the conversation.


After a week or so of avoiding the topic, Kiritsugu started explaining what Aoko (that was his mother’s actual name) had meant by ‘hero and killer’. He said, “Shirou. Listen carefully; this story is very important. It concerns my life. You see, when I was a kid, I wanted to be an ally of justice. Unfortunately, as I grew up, I realized that some people actively wanted to hurt and kill others, and nothing I did or said could change their minds. I also believed in the good of the many, so to save some people, I sacrificed others.”

Shirou couldn’t believe what he was hearing. He said, “but, wouldn’t you prefer to save everyone?”

Kiritsugu scoffed. He said, “of course I would! There’s nothing I would like more. Unfortunately, it’s not possible. In war, you have to pick a side, otherwise you will only make the war last longer, killing more people; when facing a Dead Apostle, you sometimes arrive too late, and most of the town have become members of the Dead; sometimes, it’s too risky to save some people, and trying anyway may well lead to way more people dying. I believed in weighing the number of people I would save with my actions; save the most I could, while killing the fewest.”

Shirou thought over what his father said, and realized something. Shirou said, “so, you have killed innocents just to save more lives?!” Incredulous.

“Yes,” Kiritsugu said, evenly.

Shirou tried to wrap his mind around the idea. After a bit of time, he said, “I need to think about this,” and went off to his shed, all but sprinting there.


Kiritsugu covered his face with his hands. ‘That could have gone better,’ he thought, fear clenching his heart. He couldn’t help feeling proud of Shirou’s speed and stamina, showcased by how fast he ran away, though; the exercise regimen he had put Shirou on only a week before had paid dividends already. ‘Avalon might be accelerating Shirou’s body’s natural processes,’ Kiritsugu thought, knowing that only a week of training shouldn’t have been enough for such a huge improvement.

Of course, Kiritsugu was far more strict in training Shirou than he would have been, had the young boy not been the actual child of such infamous parents; Shirou would have a lot of people after him as the son of the Blue and ’the’ Magus Killer, way more than he would as an adopted son who wouldn’t even inherit Kiritsugu’s Mysteries.

That brought along another question: should Kiritsugu let Shirou inherit the Emiya Crest? That would give the young boy more options for defending himself, but it would also bring more problems. The man had already had his Magic Crest removed in order not to risk it being affected by the Curse before he set out for Germany - he couldn’t use it well at all anymore anyway.

The next question involved donating a few of his own Circuits to put in the Crest, but that would mean the possible loss of his ability to use Magecraft, especially if he gave multiple Circuits, and he definitely didn’t want to give up on Illyasviel. He would need to think on it more.

Suddenly, the bell of the Emiya residence rang, and Kiritsugu was on alert. His senses had seriously dulled if he wasn’t able to tell someone was outside before they rang the bell. Knowing that Taiga had a key, Raiga was busy at this hour and not able to think of anyone else who would actually ring the bell, he proceeded cautiously, palming a gun.

Then, a familiar voice said, “Kiritsugu, if you don’t open this damn door right now, I will break it!”

Kiritsugu recognized Aoko’s voice and immediately paled. He opened the door, gun forgotten in his haste and greeted the woman who was on the other side. Aoko simply skipped the pleasantries and said, “where is he?”

Kiritsugu’s mouth worked without his permission and said, “in the shed,” not bothering to explain further or express his anger with his old friend.

The whirlwind called Aoko took less than two seconds to sprint to said building.


I hope they were in-character.

That was a good read. :)

Major critique is Kiritsugu's reaction to Aoko. Way I'm seeing things, she didn't even tell Kiritsugu he was a father - that gives him plenty of reason to be Angry-As-Heck at her, Blue or not.

Your description of Kiritusugu's shock is nice. Our stoic killer getting stunned - :)

I want to read more. What happens now? Would Shirou enter the Grail War with both his parents? Hmm... thinking about it, for laughs, it would be really interesting to have Archer meet them too. :D

He'll be lucky to keep one parent by that time. :p

As for Kiritsugu getting angry, I assume you mean during the heart-to-heart with whiskey-kun and Raiga? Because he's too shocked when Aoko finally comes. I might edit the previous post a bit later.

Edit: I changed some things.

I like to think his heart-to-heart with Raiga was dealing with his shock. At that point, he didn't even know he was a father. Moral issues of marriage and responsibility aside, you have a situation where a mother didn't tell the father that she was pregnant with his child (unless she was sleeping around .. let's not go there) !! Most fathers would be justly furious with the mother in those situations. Among all things, Kiritsugu isn't an irresponsible drunk - he may not have wanted the responsibility of a child, but he was never given the chance to voice his opinion.

That's all heavy stuff. I think a believable excuse could be that Aoko's family restrained her as soon as they found out about her situation - she couldn't tell the Magus Killer even if she wanted to. Then, due to events, she is led to believe that the child died (the fire?). At that point, she probably thought it kinder not to tell Kiritsugu that she had his child, but he died.

So now we have a situation where she finds out (from somewhere?) that her child IS alive, with the father and as any worried mother rushes to her little boy's side. As for her family? They probably haven't heard yet that the offspring survived.

/me blinks.

That actually IS a good plot point - it's one thing for the Kiritsugu to adopt a random child. But for the offspring of the Magus Killer and The Blue to be alive? I'd wager good money that many would want such an individual killed. Or even worse - experimented on. Let's just hand-wave how Aoko found out about Shirou as something she did with Blue and move on?

I didn't address it yet in-story, but I like to think that Kiritsugu sent a small message somehow, and the surprise he felt when she came to his home was mainly because she got it so quickly.

Edit: Now that I think of it, Shiki was ~9 (IIRC) when he met Aoko, and Shirou is around a year younger, so considering he's 8 now, Aoko is in Misaki Town, the place where Kiritsugu sent the (coded) message.

The timeline fits; she got the message immediately because she was in town.

Now I got an amusing Omake in mind, with Shiki seeing Aoko when she just got the message, then she runs off. Or maybe Shiki asking Aoko about any family she had.

This is an incomplete oneshot I had collecting dust in my hard drive for years.

"True Sisters", or "A Path Close to Happiness"


"Hello Tohsaka," Luviagelita, Finnish magus, greeted her not-so-friendly rival.

Rin grimaced as soon as she heard the voice, but by the time she had lifted her head, resignation had replaced it on her face. "Edelfelt." She greeted back neutrally. "What timing."

Luviagelita showed a serious disposition that rarely surfaced when in the presence of Rin. "Tohsaka, what's wrong? You refuse to even bicker with me - did one of my family members seriously offend you? Did I do something horrible without realizing?"

The Japanese girl shook her head. "No, nothing that has to do with you or *your* clan. But don't call me 'Tohsaka'; I no longer am one."

Luvia showed some surprise. "Your father disowned you? Do I need to *accidentally* blow up a few of his properties?" Her 'hyena' mode seemed ready to appear.

Rin was, in turn, surprised and a bit touched by the show of solidarity, but refused. "Thank you, but there is no need - I was the one who rejected the name and path of Tohsaka; he simply was forced to accede to my wishes."

Luvia was more contemplative now and, dare one say it, calculative. "What did he do?" She asked. "If this is not too intrusive a question, of course."

"It's not so much something he did. It's who he is." Rin said, rubbing her forehead. "I knew intellectually what a magus is, as well as that Tohsaka Tokiomi was a perfect magus; but the coldheartedness and ruthlessness that entails -and that the same was expected from me- became too much eventually. I could no longer deceive myself. I also refuse to practice Magecraft on my own, and Father- Tokiomi, I mean, still has over half the Crest stored somewhere, since that damn priest didn't yet deem me ready for all of it. I'm already fifteen, for fuck's sake!"

The other teenager remained silent for a few moments, then said the words that would change both their lives. "Would you like to come with me, then?"

For the first time in the conversation, Rin seemed animated. "What? What!" She calmed down. "Please explain. Or did I hear wrong?" She still was on edge, though.

"You heard me just fine. I offered to at least give you shelter for now, maybe even adopt you into the Edelfelt family, Rin-san." Luvia didn't change her expression. She didn't even react to Rin's mild rudeness, however much she was tempted to slip back into their regular (comedy-like) act.

"Why?" Rin trembled a bit in agitation and anger. "If this is because of pity...!"

"No." The European girl adamantly denied. "It is because you are family." She saw Rin's disbelief and interjected: "You did not think that all those accusations of the Tohsaka copying our Magecraft were something we truly believed, did you?"

"But how? And do you have any proof?"

Luvia got up from her seat and beckoned Rin to follow. "Let us go somewhere we cannot be overheard," she implored, calling for her limousine.

While a bit suspicious, Rin didn't think she could do otherwise -she had nowhere else to go- so she followed. Luvia was never the underhanded type, anyway, at least where it concerned their rivalry.


Inside the limo, and with every avenue of eavesdropping closed, Luvia started her tale after asking that the other girl not interrupt. "It all started during a Grail War, as many stories are wont to start - or end. The latest and last one*, the Third War.

>>A bit more than fifty-eight years ago, appeared signs that both of the heiresses of the Edelfelt clan would be selected for the Grail War as Masters. The older sister was enthusiastic about it, as were the rest of the clan. However, the secondary heiress believed they were not ready for something like that, that they were lambs to the slaughter.

>>After a lot of pressure by her grandmother who was acting as family head then, as well as by everyone else, the younger sister acceded. So they set out for Fuyuki. They summoned two aspects of the same Spirit and participated in the War.

>>However, the younger sister was proven right. The teamwork of the two suffered because they never could get along; they were both somewhat immature and very prideful, though they truly loved each other. Eventually, that lack of good teamwork resulted in the death of the older sister. Enraged by what happened, the younger sister fought really recklessly after that.

>>Even though the Servant was less strong than a Saber would normally be without her counterpart, the younger sister managed to eliminate all the remaining opponents but one thanks to her intelligence, skill as a magus and bold actions. Both Servants perished in the final battle, and the prize of the Grail remained unclaimed.

>>After that, our information ran dry for years, but we later pieced together what had happened. The former secondary heiress remained in Fuyuki, abandoning the clan due to her bitterness against all of them; she likely blamed them for losing her sister because they insisted on their participation in the War.

>>It was the last place anyone expected her to be. She started staying with one of those she defeated in the War at some point, and they fell in love and got married. His name was Tohsaka Yahiko and he had been the Master of Lancer.

>>The older sister had already married and had a child by that point, which is why the younger sister had been without pressure to marry. That orphan child was my grandmother. The child the elder sister later had was your father."


Rin was silent, trying to digest the tale.

She then said, "so, why do you and your family insist that we were Crest thieves, if the younger sister gave it willingly?"

"...It is our greatest shame. Family is very, very important to us, the Edelfelts," Luvia said, "to chase away one of our own like that is anathema, though some blame the younger sister herself for abandoning her family in this case. You know that nobody in our clan has been allowed to set foot in Japan if there's the slightest chance there will be a Grail War soon, right? That's why."


(Eventually, Rin is adopted by Luvia as her sister in a rather unpopular decision, possibly getting half the Edelfelt Crest, too.)


*Yes, no Fourth or Fifth War
