Hey, Its Hirem. First this story will for the firt few chapters focus on training and juicey action or Lemons will be when the alotted day of the Moon ends So Be patient. This is shorter than intended because I needed time to rest.

Begin!


"Are you serious?", Kiritsugu asked. He now barely had the appetite to finish his burger. "My son is getting educated by three of the most elusive and terrible mages not allied with the Association."

"Technically, he's being taught by dolls mimicking them through his crest. But yeah.", Genmu clarified." It isn't that odd. Afterall, these are the spells he'll learn first before your Crest will be accessed."

"That's another thing. You were so adamant that I pass my Magic Crest to Shiro even though he should be incapable of inheriting it. Yet there he is, training to be mage, using Innate Time Control along with the basics I just taught him. And in just 6 months he uses them so naturally that I'd almost think he took years to master."

"Why not give Illyasviel the Crest instead of Shirou?" Genmu finished what Kiritsugu was asking while he fished out two beers and gave one to his partner. "I got five reason for you."

"Five?"

"Yeah," Genmu and Kiritsugu opened their beers and they continued," First, Illya is an Einzbern. She already has a Magic Crest and is already strong enough without yours. Shirou, on the other hand, needed another Crest to be integrated into his due to the weaknesses of his craft. Second, Illya is still a vessel for the Holy Grail."

Kiritsugu tensed at the mention of the Grail, recalling his failures and suffering because of it.

"I may have said that I could separate her fate from her body. That is, remove the Grail from her body without harming or taking her magecraft away. But to be honest, it'll take about ten years to complete the operation. If Illya inherits your Crest, it will lead to complications for her operation. I may be good, but I'm not arrogant enough to do a double operation."

Genmu looked at Shirou as the boy dodged several hellfire arrows, before connecting space to return them back.

"The third reason for giving him your Magic Crest was to ensure the Emiya line stayed strong." Genmu explained. "With Illya being the Einzbern Master, the Emiya line must have a candidate of their own. Unfortunately, he is only the adoptive son."

"But you modified his body to be both compatible with the new Crest and merged it with his own." Kiritsugu said, remembering what Genmu said when passing his Magic Crest to Shirou. He looked at his son before turning to Genmu." I still can't believe Shiro actually had his own Magic Crest."

"Yeah, I couldn't believe it either when I read the report," Genmu added. "Kid was a top priority investment. Took me a few days to get the files needed and even then, they say very little. That's actually the 4th reason."

"E wanted us to protect him?" Kiritsugu asked.

"Yeah," Genmu nodded." I didn't know what top ranking family Shiro's from. So, I took a blood sample while transferring your Magic Crest and took it to our lab."

"And?"

"And now we go there to review what Shiro just learned from those three." Genmu finished by pointing at Shiro. Kiritsugu looked and saw Shiro had defeated the Kioku Doll. He was beaten and exhausted, but he was still standing. The doll on the other hand was split in two cleaved with sword that was slowly fading from existence.

Shirou POV

Shiro was right now exhausted.

Normally he could defeat the Shrine with several options. It would have been difficult, but he was 94% certain of victory. But fighting the Noble and Witch used up a lot of magical energy. He had to deal with the floating arrows, talismans, and star charts cannons. Every time he was about to land a blow or dodge, often a trap or a hidden arrow was right where he was standing.

But something was different during the scuffle. First, there were times when he would dodge the arrows before they hit him. He would use flash Air to avoid attacks. Then, he began seeing mirages of his opponent moving in different directions, with the most solid image being the next move of his foe.

Before he realized what was happening, Shiro had penetrated his opponent's defenses and had sliced it in two.

Now he was exhausted while he waited for his mana to recover.

He had learned magical energy was composed Od (power of the soul), Prana (power of the body), and Mana (power of the World). But he simply called it Mana despite the different usage for each.

And now he was feeling for what he had been waiting for.

His prize.

Shiro arch his back and spasmed as intense pain and pleasure racked his very being. He gritted his teeth and endured for 30 minutes. Each victory increases the time and burden.

But he also obtained power and understanding.

When he first bested the Noble the first time, he wasn't prepared for the agonizing pain with the Flash Air spell. But he managed to endure. And every spell since was easier.

The Witch's test he only bested her once, and he still trying to grasp it. Because if he really understood it, he would feel his body take on the burden.

Witch Blood.

The spell was simple, yet parts of it were hidden from him. Apparently, he had only won the right have a practice I, but not comprehend it.

Well, no matter. He'll deal with it with Genmu and Kiritsugu.

As he felt the strain ease slowly, Shiro couldn't help feeling satisfied with the results.

The Shrine doll was the intermediate between the Witch and Noble, but it hit him more than the two combined. Those arrows were mainly the problem. They moved at such dynamic speeds and angles that Shiro even at one point thought they saw the future.

Even the Shrines first spell was baffling.

Celestial eye.

Shiro was uncertain of the specifics, but that spell was generally an enhanced eyesight spell. When he used it, he felt he was seeing every detail he saw near and far and all around.

He could understand seeing object to be useful, but he couldn't understand the purpose. Perhaps because he doesn't know what their magecraft dealt with.

Even more so with the new spell: Divine Circle.

The instructions to utilize it are now in his Circuits, but something told he shouldn't practice without mastering the Celestial Eye.

"Not testing the new toy? Smart," Shiro Turned around to see Genmu and Kiritsugu walking to him. While Genmu looked amused, he saw Kiritsugu looking tired. He's been noticing it getting frequent as time went on. "Based on your look, you can't use that new spell he taught you, huh?"

"Dad. Genmu." Shiro blurted. Normally he would train in their Realms for new lesson. Whether it be with Kiritsugu for Time manipulation and the art of Mage killing, or whatever crap Genmu would teach him, he always did in their territory. Them being here either meant there was trouble, or they were watching him train and wanted to impart some advice.

"Shiro," Kiritsugu smiled. "You're working hard I see. Any trouble?"

"Yeah I am. And I can't make heads or tails of this new spell he gave me."

"Well, we can you understand it. Right Gen?" Kiritsugu looked at Genmu.

"Right, Kerry. Just give us every detail of the spells effect as you can and we'll try to figure it out." Genmu reassured the boy.

"Well, it's sort of like this," Shiro began explaining about his struggle with the Celestial Eye and the divine Circle.

How The 1st spell made him feel himself seeing everything around him with such clarity and understanding along with the slight headache. How the second spell couldn't be used effectively without the first. And that even though he could use it, he couldn't use it effectively and didn't understand its function.

"I mean, why give me these two spells? Enhanced sight and what appear to be drawing circles."

Kiritsugu and Genmu both at each other. Then at Shiro. Finally, Kiritsugu opened his mouth. "Shiro, did you look around you after beating that doll?"

Shiro looked around. The Shrine's arrows had returned with him, but the damage was still there.

"Here, let me show you." Genmu activated a dial mid-air and turned it. The tile on arena floor all three were on levitated. Shiro looked again and saw what Kiritsugu meant.

The entire area he had been fighting in was carved into a large multiple linking circle with smaller circles inside.

"See, while you were focused on dodging the arrows, charms and blasts," Kiritsugu explained. "Your opponent was preparing a magic circle to both slow you down and augment their attack power and speed. Based on the state of the area, I would bet in just four moves you would have lost."

"You got lucky kid," Genmu added. "Had you not used the Celestial Eye properly and not attacked. You would have failed again and had to Face the Witch."

Shirou shuddered at the mention of the sweetest but most dangerous of the three doll tutors. "Wait what do you mean I used celestial Eye properly."

"Just as I said Shirou. You used the celestial Eye spell in a way that it was useful, and the Shrine gifted you with the next spell after you won."

"You see Shiro these dolls Gen made were special," Kiritsugu explained as he made an image appear showing a diagram of the three tortur- he meant tutors. "Using Market magecraft and cutting-edge virtual reality science, they replicate what spell on your Magic Crest to give you a more practical experience."

"So, if they use my Crest why couldn't you teach me these spells Dad?" Shiro asked as he winced from pain." Why force to fight these powerful (Psychotic)Dolls?"

Kiritsugu looked at Genmu. At that Shiro knew he would get his answer. Whenever Kiritsugu deferred to Genmu, Shiro received crude, but simple logic and it cemented his belief that Genmu must be skilled if Kiritsugu trusted him.

"Stardust, your daddy can't teach that magecraft for a simple reason," Genmu said. Shiro shivered at that nickname.

Shiro waited for the answer with 50% fear.

"It's not his magic."

"Eh?", Shiro said dumbly. All three of those monsters were using Magecraft Kiritsugu didn't know.

"Seeing that dumb goofy look of Yours I suppose is should explain from the beginning. Or at least the bare basic until you beat one of them." Genmu sighed. There it was. Him calling Shiro dumb.

"Ok?" Shiro wondered curiously. Despite his behavior, Genmu was an effective teacher. Hell, Kiritsugu even Joke that if he wasn't such a greedy, pervert asshole, The Mage's Association would have hired him if they heard of him.

Another feat of the Market.

"Kerry's magecraft deal with Time. As you so graciously used to run like a little bitch." Genmu insulted. "But as a mage he only refines the combat applications and thus he's only good at teaching your kids the art of killing mages."

Shiro understood that. Kiritsugu had drilled into 75% of what he knew into Shiro for the past 6 months and the rest went to Illya. While he may have bee harder on Shiro than Illya, Shiro didn't mind. Guys should always protect beautiful girls. Or at least that one of the proverbs Genmu spouts drunk.

"The reason we gave the Emiya Crest to you instead of Illya is related to her treatment." Genmu explain in a bland methodical voice. "She can't inherit it with increasing the time it takes to get better. SO, we went to you."

"Because I am the only one left." Shiro finished. "But wait. I'm Adopted. I can't inherit the Crest. You told me."

"Yes, I did. If it were normally the case," Genmu clarified." It is quite simple to transplant a Magic Crest to an Adoptive child. Hell, there is even proof of it happening."

"Really, who-?"

"Unimportant Stardust," Genmu cut him off. "The point is I modified your body to be as compatible with the Crest without changing or killing you as I can. That's where I found the issue."

"Issue?" Shiro felt worried about Genmu's statement. His next word shocked him further.

"You had already posed a Magic Crest of your own." Genmu said casually while discarding his beer. Recycle to save the earth.

"WHAT!?" Shiro yelled in surprise. "But I wasn't a mage before meeting dad. How could I have a-?!"

SNAP!

Shiro felt as if his were smashed with ten sledgehammers. He groaned at the sudden hit while rolling on the floor. "OW!"

"Stardust," Looking up Shiro saw Genmu fingers and quick clammed up. "Good. I was shocked but then looking at the design of the Crest its quantity and quality were exquisite. How could someone of common birth have such a Crest. There was only one answer that fits."

"My family used to be Mages a long time ago." Shiro finished Genmu train of thought.

"Exactly, Shirou. It isn't common for Mage lineage to disappear. But rarely did they remerge from obscurity." Kiritsugu said sagely. "Gen took a blood sample to find the lineage in the Market archives. And although company policy forbids him from saying their name, history, and existence. I 'm certain he's allowed to give you a dumbed down summary of the crest."

Kiritsugu looked at Genmu as if daring him to contradict him.

"Yep," The pervert agreed casually. "I can tell you about that Crest on the condition you make significant progress. Seeing as you gain five spells from those three, I can at least give a summary of what you're dealing with. But not their trump cards, names, and history."

"Just their Magic?" Shirou asked.

"Just their magic," Genmu repeated. His stoic tone and body slowly shiver before he began laughing with that same shit eating grin. "But man, you really suck! You got beat by a magical girl!"

""I knew IT!"", Both father and son yelled at their colleague with the realization he was using teaching to humiliate Shiro.

20 minutes of varies punch kick and wrestling moves later.

Shiro and Kiritsugu were currently practicing Buddha training and succeeded in reaching enlightenment. Between the pair was the mass of lumps Formerly known as Genmu Fuujin.

"I... reget…nudding...!" (I regret nothing!)

Seeing the scoundrel perverse smile, Shiro and Kiritsugu sighed. The latter looked at his partner sternly." Alright Gen, hurry it up Shiro still needs to complete the next lesson before dinner."

"Fine," Genmu took out a potion and doused his body in it. In a stop motion, his body soon returned to normal. "Stardust. Kerry. What should I explain?"

"You can start Genmu," Shiro began. "By explain what he heck the Shrine was doing?"

"What? Not the Noble or Witch?" Genmu perked his eyebrow.

"Those can wait. But out of them, the Shrine seemed the least inclined toward attacking but more on..."

"Defense and surveying." Genmu finished. "You aren't wrong. Considering the branch, it dealt with was divinity study."

"Divinity study?"

"Shiro, from the data gathered, that Shrine doll specializes in sealing, defended, warding and tracking opponents. Have you noticed it dodging some of your sure kill moves? Erecting barriers before the kill. Diagrams appearing to lock you in place?"

Shiro thought about it and realized that Genmu had a point. That doll was predicting every move he made!

"In other words, Shiro," Kiritsugu warned. "If you can't predict and counter its formations the Shrine will beat you harder."

"Yep, based on how that guy looked, you'll have to confuse him before he fires, or outsmart and outthink him to win." Genmu concluded.

"Aren't outsmart and out think the same thing?" Shiro asked confused.

"Nah, they are aren't Stardust," Genmu answered. "Outthinking is guessing and preparing for the attack. While outsmart is tricking the opponent into making a mistake."

Uh-Oh.

"For instance," Genmu snapped his fingers and Shiro felt his body get smash with the feeling of a sledgehammer to the ground. "In all three of your sessions you always stat with powering through against the odds. Trying to match power with power and resolve with resolve."

Genmu snapped his fingers again and the weight increased on Shiro's body twice.

"That would commendable and brave, but 9 out 10 times, that approach was self-destructive and stupid."

Another snap and Shiro felt his limp feeling torn up, resewn and torn repeatedly as the pressure increased time 7.

"When fighting the Witch, you already knew her chant speed was gradually getting faster, and you just ran into her attack range. You could of flash air to her location and finish her off before she cursed you and finished her spell."

Genmu snapped his fingers again and this time the pressure vanished but Shiro looked at his body for any changes.

Genmu was an excellent teacher, but his sadistic tendencies and eccentricities were wired not in physical torture but abject humiliation.

And Shiro was wearing the proof of that.

He was wearing a blood red and cyan dress with frills and feather accents on his shoulders and waist. He had black gloves extending to his elbows. He wore black combat boots tipped with rubies and silver accents.

Overall, Shiro was wearing a frilly dress for and Magical girl.

T-this is something from those magical girl shows Illya been Watching!

Yes, as mortifying as Shiro felt, he was now wearing a magical girl/ maid outfit.

"Right then Stardust, this is your punishment," Genmu explained was he could barely contain his laughter. Kiritsugu could barely hold his lunch and psyche at the cute magical girl-boy outfit Shiro was wearing. "Until you Master and accept those spells, you're stuck training like that until you achieve that goal. And for added measure…"

Genmu gave Shiro a simple iron baton and put a metal collar on his neck with a padlock.

Shiro felt his power waken significantly. He realized what Genmu had done.

"With that on you can't use Tracing, Time alter and other magic. The only spell available would be what those three gave you."

Genmu took out a card and flicked it on the floor. Immediately a large ornate double door appears and Shiro began to fall.

"Hey wait…!" Shiro pleaded before Genmu flick another card and blasted him to the abyss.

"That collar can only be removed with the key and it would take a Bloody Witch to survive that ordeal!"

And with that the gate closed and Shiro was gone.

Shiro POV falling

Shiro would wish he could brag that what Genmu put him though was easy. He would want to say he elegantly completed his task.

However, four things were occupying his mind.

He was going to make Genmu pay for put him in this outfit.

He was going to die falling.

How the hell was he going to fly.

Crap. Crap. Crap. He' going to Die!

Luckily or unluckily, Shiro spent 6 months being taught by Kiritsugu and Genmu. His father taught him the important of remain calm, so as Shiro plummeted to sudden death he activated Thought acceleration to weigh his options. Genmu' tutelage gave the boy a flexible strong mind, so he immediately executed his land strategy one he calmed down.

Using flash air to create portals, Shiro fell in one and fell up from the exiting portal and repeated the process. Then using reinforcement on his outfit, he turned it into a gliding suit. Finally, in his desperation he mange to use the Divine Circle spell to create air pulsing circle on his boots and back allowing for adequate hover feature to fly ad descend.

When he landed safely, Shiro sighed in relief. He managed to fly due to the memory of watching that magical girl anime with Illya.

Looks like Illya was right. Magical girls (or boys in my case) are supposed to fly.

Still he looked around his surroundings. He was in a frozen winter wonderland with Mountains and Evergreen trees and snow. Farther away he saw a tiny building that looked like a castle.

So Genmu sent me to Illya's Realm. Figures he try to milk this as much as possible.

Shiro weighed his options. He was limited to the noble, Shrine and Witch Magic. Alone in an unfamiliar territory. And wearing a dress.

The only upside was this sealing collar was emitting a light pointing him to what he concludes was the key to removing this stupid outfit. Shiro began following the light.

"He did say that the key was here. But what did he mean by bloody witch?"

Back to Kiritsugu and Genmu.

"Why did you force Shiro to wear something that gross and sent him to Illya's realm?" Kiritsugu questioned. "And don't say you did it for shits and giggles. You always help out proportionally to how much you fuck with us."

"I wanted to engrave the lesson of tolerance into him." Genmu said emotionlessly.

"Tolerance?" Kiritsugu tensed. Whenever Genmu became emotionless and cold, he always felt as if he was face three of himself. That and Genmu was about to disclose something dangerous.

Genmu snapped his finger and began type on a hologram circle. Two chair and a round table appeared. Both sat down and began to talk. "Shiro idolizes you Kerry."

"I know, But he shouldn't." Kiritsugu agreed sadly. "I wanted him to live a normal life away from the irrationality of Mages. But kids will always strive to emulate their parents."

"They do," Genmu said. "Which is why that kid must grow to understand and have impurity."

What?

"Kerry, you probably didn't notice but Shiro is empty." Genmu said emotionlessly. Only this time he said it with a tinge of sadness.

"Empty?", Kiritsugu considered that before he realized with Genmu meant.

"Shiro values other peoples' lives more than his own. When you save him, you inadvertently imprinted him with a curse more terrible and eviler than any magecraft known.", Genmu explained. "I 've check his psych profile during the past 6 months. Kid's a helpful brownie."

"What curse?"

"I can't really say," Genmu said. "And not because I'm omitting anything, but because I'm still compiling a theory."

"You're trying to teach him something aren't you?", Kiritsugu guessed. "But besides tolerance what?"

"I have no idea what you're talking about." Genu denied as his summoned a crystal ball and cast a remote viewing spell in the form of various screens.

The screen shows live video of Illya frozen mountain Realm along with Shiro in the embarrassing magical boy outfit.

"What Shiro currently lacks is a flexible, pragmatic mind." Genmu looked as the boy was flying towards the target with improvised magecraft. "He doesn't realize the power of darkness and heretical skill like yours. Especially considering that one of his lineages is actually involved in dark magic."

"Who are they?" Kiritsugu interrogated. "There had been rumors of other families involved in the Grail ritual, but they've all been rumors."

"Let's start with the first one," Genmu agreed and took out one of the files.

It showed a very stern, angry, but handsome young man.

The Noble.

"Alexus "Aizen" Ainsworth." Genmu began. "Young scion of the extinct Ainsworth family. Younger sibling to Zachery Ainsworth the previous head of the family and uncle to Julian and Angelica Ainsworth. All Deceased."

Yeah, right. Kiritsugu thought. From the grape and for the past six months, he's had his suspicions but he certain now.

The Market slaughtered the entire Ainsworth Family!

The bodies were deprived of life and the magic circuits were ripped apart and the Magic Crest and other treasures were stolen. But given all the items Gen was using, his conclusion was 92% accurate.

"An old English family their magecraft focused on the flash air technique of Alchemy, as well as various rare spatial magecraft. However, their most prominent and much more well-known contribution is possibly why their demise was terrible."

Mystic Codes.

The Ainsworths were the Mages Association supplier of mystic codes and magical constructed artifacts. With them gone the Clocktower lost a tremendous backer for its strength.

"Alexus was merely the spare heir as the Ainsworth 1st heir was still living and had children. Instead of continuing the tradition of dueling in craft for the title the young fled to japan and went into hiding. Using his skill, he helped al the poor soul until receive the name Aizen. Died under special circumstance."

Genmu took out the Shrine's file showy the blank faced youth Shiro just fought.

"Kioku Sakatsuki," Genmu began. "Only child. Heir to the Sakatsuki lineage. On the surface, no relationship with the Mages Association and less with the Asian branches. But the Sakatsuki were prevalent in one piece. Deification of children."

"Children?"

"Ancient Japan the mortality rate for children was high. Those that survive were revered as gods. While modern time has faded that myth, this family practiced it fervently. They would raise the children away from the outside, cut from contact with multiple bounded Fields until the child turned six to ten. That would be the time when the god became human."

"Why would do such a thing?", Kiritsugu blanched. He had seen and done awful thing, but he still drew the line with children.

"Based on the texts deciphered by Market keys, they were harvest Akasha." Genmu read the file while taking a sip of his beer.

"Akasha? How would one harvest the root?"

"Well, they were actually in dumb-dumb term asking the gods for wishes."

"You mean?"

"Sakatsuki gods gain the power to grant powerful but limited wishes. However only the females of the lineage have that condition and power. Male it seemed were conditioned as guardians. Thus, the wishes made would differ. Possibly because of the rituals, the lineage magecraft specializes in celestial bodies, prediction, clairvoyance, acquiring knowledge, barrier magecraft and dads of Shinto, Buddhist teaching and Hojutsu and Onmyoudou."

"So, they can't fight, but they can subdue their opponents and predict their moves." Kiritsugu nodded with understanding. Shiro fight with the shrine recalling the arrows.

Divining Moon Arrow…

"Hang on. What about those arrows."

"No idea, but if I wager, they are arrow per say, but maybe ritualistic tuning rods to improve energy flow. Combining their study of the gods magecraft with Einzbern's would explain the cycle of 60-year interval. And combining the Ainsworth dimensional powers, it would make sense why Fuyuki was chosen."

Silence until Genmu opened his mouth.

"But Kerry, even if they seem weak, Sakatsuki actually proved a theory the market had been trying to crack."

"What theory?", Kiritsugu asked.

"Nothing much just the decline of the Matou family." Genmu said casually. As took the last file.

"Wait a second. Your telling they actually managed to destroy one of the three-!?"

"Moving on!" Genmu interrupted, taking out the Witch folder. "Kerry, meet Ayaka Sajyou. The Witch of Formality."

"We're not done, Gen." Kiritsugu relented." So, what her story?"

"Oh, nothing much really," Genmu read the file. "Second daughter of her family. Elder sister fought in the 3rd Grail war. Learned witchcraft, Formal craft and Blood magic. Overall, wimpy and pretty. Married into the Sakatsuki family. Still, out of all three her accomplishments and stats still being decoded."

"That's a lot of Nothing!" Kiritsugu yelled. "I don't know what's more shocking. She married the into the Sakatsuki line? She's a witch who use one of the most useless branches of magecraft and the most heretical one? Or that her sister fought in the 3rd holy grail war?"

"Maybe the fact that she's actually Shiro's biological maternal Grandmother." Genmu commented lazily. "Uh-Oh."

PLOP!

Kiritsugu comedically fell off his chair. For a serious man like him to do such a thing was both alarming and serious. Genmu wished he had a camera.

Kiritsugu stood up and walked toward Genmu. He got to his chair. "What the hell are you planning?"

"Pardon?" Genmu raised his eyebrow. All casualness disappearing and Kiritsugu was seeing his partners pragmatist side.

"You come into my home. Bring my daughter from the Einzberns and force me to teach magecraft to Shiro seriously. Then, after six months, you land this bombshell of information that could potentially destroy Fuyuki. I find out that my son had family and I'm certain the Market had a hand in killing them to get to me. So, I'll ask again. What hell are you planning?"

Genmu looked at his friend and decided to give him some facts. "The Market's interest in the-"

"Stop." Kiritsugu interrupted. "Let me rephrase the question. What the hell are you planning, Genmu?"

"What are you talking about?" Genmu asked back. "I'm just a sales rep for the acquisition of TEM products and investments."

"I'm only an agent for the Market," Kiritsugu explained. "But I know when big fish are around due to all the jobs I took. Which I'm starting to thing were from you guys with you Gen as the handler."

Genmu kept quiet and Kiritsugu looked at him while continuing.

"You managed to fool everyone we meet about your true nature, but even with the growing stomach ulcers to prove otherwise, I knew you were hiding something. We're both mages, piss poor at that, but still mages. You don't do anything without a price or reward. You're helping Shiro and Illya train while protecting them but from what or whom."

"Where's the proof?" Genmu asked. "I'm a selfish, greedy man. I only do things for profit and to laze around house masturbating on otaku shit. What proof do you have that I'm a big shot? A protector."

Kiritsugu spread his arms around the space they were in. "The Reflect Refrain. This entire space requires vast funds and resources to develop. Resources the Market probably made or stole from the Mages Association. Plus, even though rumor say our power been restricted, I believe otherwise. What are you planning, Genmu? Why help Shiro learn my Crest, and his Families. Why did you kill them? Are you after my Son and daughter too bastard!?"

Pew!

Kiritsugu herd and felt something cut his cheek. Turning around he saw what had gazed him.

A business cards.

"Kerry, don't assume that I'm the one that will kill them." Genmu warned. Kiritsugu felt his spine shiver as he sensed Genmu's mode foul up. "You may have severed the bonds of life throughout your path. But don't assume that I will harm them!"

Kiritsugu saw Genmu change. Though minute, he saw it. And then it was gone.

"I'll tell you his connection Kerry," Genmu calmed. "But right now, we got to see if he's smart enough to use Ayaka's spell."

Kiritsugu nodded and looked at the screens. Shiro was still wearing that awful outfit. Only this time he was also chasing Illya with a bunch to hungry wolves.

"Why Ayaka's spell and did he really have to wear that outfit."

"Hey, Ayaka spell need resolve and flexibility." Genmu answered. "Plus, this will help Illya with that magic wand I gave her."

"I still can't believe you took that wand from the Wizard marshal as collateral and made Illya dress like that."

"For the record, that vampire owed us money," Genmu defended. "Besides, I think Illya liked the outfit."

Kiritsugu looked at the image of his son being forces the pursue his daughter. "I still can't believe you exposed them to that anime crap."

"What can I say? They needed to enjoy entertainment as kids," Genmu reasoned. "God knows they need a hobby with what have planned. I'm just sad that Shiro didn't develop an enjoyment for it."

"but we'll still try."

"Yep."

Illya POV

Illyasviel von Einzbern was currently a happy young girl.

Well, usually.

She had an unhappy life in the two weeks when her mother and father left the castle. She cried when the memories of her mother's death came to her. And even more with hatred when her father never returned.

But she also cried even more when he came back.

When she saw her father, all that resentment vanished. She ran to him in a warm embrace and cried. Her father was home.

She felt a maelstrom of emotion that day.

Joy and love for her father's return.

Sorrow and grief at the state he was in.

Shock and panic at a mass of stupid being flung into her room.

And Grandpa Acht face of sheer anger following.

Next thing she knew, she was witnessing her father's idiot partner threaten and convince grandpa to let them go. Her summoning Berserker early and getting meet her younger brother Shiro.

When she met him, she thought he was boring plain and a bit serious. But these past months of training their magecraft, watching anime, and dealing with Genmu's shit. She finally realized her own feeling.

She was in love with Shiro.

She would never acknowledge it given the relationship between them, but his kindness that rivaled her father, his elegance in the house matched her taste as an Einzbern, and finally his determination that even surpassed Berserker won her over.

It also helped that he was cute as a younger sibling, despite Genmu's mad rambling of being well- endowed and her being a younger sister play addicted brocon. Whatever that meant.

Yes, all this made her happy.

What doesn't make her happy was fact that Genmu blatantly modified her magecraft training to not only in the Einzbern training and rehabilitation from the Holy Grail experiments. Another aspect was the stupid magic wand that was her personal Mystic Code and partner with this embarrassing Magical Girl dress.

It was pink and white making her light and feathery. There was a little crown on her head that clashed with the outfit. When she tried to remove it, she got electrocuted so she gave up on that idea.

Apparently, she was to continue her training while protecting the crown. She really hated the parts that Genmu changed in her regimen.

But she does find the outfit and powers cute and cool.

But all that pales in comparison to her training while chase by training dolls representing her three important male figures.

Her father, wearing an adult female BDSM outfit.

Her Servant, wearing a frill French maid outfit with lots of makeup.

Or her brother in a cyan Magical girl outfit.

For six months!

So, she made a vow while fleeing her lewd embarrassing doll brother.

She'd make Genmu pay!

Or at least, buy her more Moe anime and games for the next decade.

Present

"Not Again!"

Illya was wailing as she tried to fly away from once again another lewd doll posing as her brother Shiro.

Normally she would run away like the coward she knew she was before devising effective plans to neutralize her opponent. Then complete the training by bonking them in the head with her wand.

But this doll was different.

Not was the outfit blood-red along with cyan but even is attack pattern was different.

It countered every simple spell she hit it, and besides the more complex ones, she was forced to run.

Or in this case fly.

But that Shiro fake was fast. It seemed to teleport quickly to her. Whenever she attacked, it erected circular barrier before firing them at her. Worse were the blood red tentacles and black feather boxing her in.

She didn't tell anyone, but she accidently looked at Genmu's stash of cartoon s with tentacles. Afterward, her disgust of the man grew, as well her fear of that one fact made certain.

The natural enemy of a magical girl….

Were Tentacle slime!

With Kiritsugu and Genmu

"Why are you such disgusting pervert?" Kiritsugu complain as he watched his son and daughter battle in some weird tentacle play while training.

"Ask the girl who peeked at my personal stash. If I fulfill my contract, I can do anything."

"But really Tentacles?" Kirtisugu looked disgusted. "Slime would have been more versatile in weakening her defense… Wait. Hell no! Why am I discussing this with you?!"

The worried father glared at his moronic partner.

"The Mage Killer still lives," Genmu smiled looking on. "Your power may be weaker, but your instincts are sharper. My lewd mockery aside, both children need actual sparring partners for their next step."

Kiritsugu looked at the image. He hated that Genmu was a twisted fuck at times, but also a logical professional at the rest as well.

Illya's magecraft was Homunculus Alchemy. Normally this branch has no combat ability. But it could if practiced. Like the Ainsworths, for example. They were alchemist as well, but the Einzbern focus on creating the perfect being and magic, the Ainsworth developed the perfect tool and application. Illya's core magecraft just doesn't have that many combat focused spells.

This was exactly why he taught Iris some battle magic, so she could defend herself. And probably why Gen gave Illya that powerful Mystic code.

Wand of Sapphire-Ruby. A Mystic code of 2nd magic. This gave it many incredible cutting-edge features and a near endless supply of mana. By give his daughter that wand, they were teaching her how to develop her combat sense and self-control as well as developing her imagination.

Plus, Kiritsugu hated to admit that Illya was sort of cute in her outfit.

God damnit! His children were being used to turning him into a nerd.

Shiro in contrast has plenty of combat magic seeing the results of those three dolls and his use of Time and Strength magic. But he severely lacks the versatility to use them and the pragmatism of battle. He mainly just charges forward and dodges until an opportunity arises.

Genmu was right. Shiro's way of fight was akin to an idiot.

So, Genmu must have designed Shiro's training not by the context of being stronger, but by being smarter and less suicidal.

But why? Its not like he has no personal…

Oh.

He did. So Kiritsugu would have to keep looking has he daughter grows to be splendid.

And his son walks the path of a man.

"Hey Gen, pass the beer."

Shiro POV

Shiro was currently chasing after his adoptive sister, who for some reason was wearing a cut magical girl outfit in the snow. He quickly noticed some of Genmu's curses on him.

First, he can't seem to talk to Illya. Or to be more accurate, whenever he tries to talk, he words end up being lewd provocation that made Illya either run away or try to kill him with wired birds or blasts of mana from that wand.

Probably to keep them from cooperating.

Second, was that he was compelled to catch Illya. Based on this Geiss, he was forced to capture her using the spells allowed for him and take that crown to break the Geiss.

But illya was fast and strong!

Every time he erected a bounded field around, she, she tore through it with her wand. Whenever he used the plants to bind her, those birds cut her loose. And teleporting, she just hits him with mana enhance stick and run away.

He's had to adapt his strategy to wearing her out or ruthlessly pursue several times now.

It was overall frustrating, and he knew both were running out of time.

But…

He was learning more and getting stronger!

He realized the Witch Blood wasn't just a blood control spell, but a life sign detector!

And that as the chase went on, his eyes and senses were seeing things clearly!

There!

Shiro soon casted revolver door and the area designated twisted Illya flight path straight to him.

Illya meanwhile combined her bird wires into a drill and accelerated flight toward Shiro.

Both siblings knew that to dodge would give the other a chance to retaliate.

So, they kept going.

Until a flash of light appeared.

Kiritsugu and Genmu

"So, they manage to make the right choice." Genmu commented as he reach out his hand to take a sip of his beer. "Those kids are progressing even further than intended. But that also means we'll have to up our anty. Right, Kerry?"

"Yeah," Kiritsugu agreed. He saw both his children had about hurt each other when Genmu gave him the remote and he pressed pause. "I can't believe you put a time dilation feature in this dimension."

"Well, to be fair, it is based off the Emiya Magecraft. But hey the Market delivers."

Kiritsugu still didn't like how Genmu enabled Shiro to inherit his Crest along with having his own. "You still owe me an explanation on those three families and their relationship to Shiro."

"Fine, fine." Genmu said. He took out a folder and handed it to Kiritsugu. "Based on my investigation, we both got involved in some upper corporate shit."

Kiritsugu opened the file and saw the documents that made him widen his eyes. Inside were genealogical documents, magical diagrams, investment charts and the like. But it was the diagram that he focused on.

Einzbern, Tohsaka, Matou/Makiri, Sakatsuki, Ainsworth, Sayjou.

All six were in a circle in a Star of David. And at the center…

Was the Holy Grail.

"What the Hell is this, Gen?" he showed the diagram. "Why are there the name of the Three Founding Families along with those three?"

Genmu put the document on the table and point at the image with a pen. "You heard the rumors that these three along with the other created the Holy Grail War?"

"Yeah?"

"It's actually true."

"How?" the Mage Killer asked confused. "There has been no evidence that completely confirmed that rumor."

"What if those families were either, banished, hidden, or their information was guarded?"

"The Market?"

"Yeah, we discovered the Sayjou and Sakatsuki families merged into one. Then, after digging deeper we found that their descendant somehow married the second son of the Ainsworth lineage."

"And the result was Shiro."

Genmu shook his head. "Truth is, Shiro wasn't the only one. He had a younger sister named Miyu."

"But?"

"She died." Genmu said and Kiritsugu noticed that his partner was very sad. "She used her wish to wish for her brother's happiness and used her life to actually ensure his Sorcery traits progression. Possibly as a reaction to his father's death."

"Death?"

"The Ainsworth in terms of alchemy were below the Einzberns but exceled in Mystic codes and spatial magecraft. They possess the Sorcery trait that not only enabled to have multiple descendant as heirs, but always store their spells into a main terminal for the head to the family."

"But Shiro's father went against them and was killed."

"Yes," Genmu nodded. "by his own nephew and niece. Before he would be discovered, The Ainsworths were slaughtered and their Crest stolen to ensure the last heir a proper place."

"What does all this have to do with the war?"

"I'm getting there, Kerry" Genmu reassured. "Tohsaka developed the land and the servants, but Ainsworth developed the classes, parameters, and catalyst required for summoning."

Genmu pointed at Sakatsuki's name. "These guys were special. Generation of wishing prosperity gave rise to the sorcerous trait of advanced learning and integration. Using that they developed the leyline circulation interval for the grail to appear in the war while the Matous created the Command Spells."

"Learning?" Kiritsugu wondered.

"Ever wondered how Shiro was able to easily use the Emiya Time magecraft despite being the adoptive son?"

Realization dawn on Kiritsugu on why Genmu was confident in transplanting the entire Crest. Shiro learning ability didn't just apply to his mind.

But also, his body and soul!

"It is this contribution to the Leylines that all but outright sterilized the Matou line." Genmu explained while Kiritsugu waited for more. "The Matous weren't completely making excuses. The land of Fuyuki was killing their magic potential, but it was also their attitude. The inherent evil in their bloodline basically shriveled their magic circuits through the generation. That guy Kariya got magic circuit because he was such a decent person."

"They turned Morality into a curse?" Kiritsugu shuddered. If he had pissed off such a family, nothing he could do could stop them.

"Well they had help from the Sayjou family, but yep."

"Oh great, what did this family contribute?" Kiritsugu waited with curiosity. Throughout this conversation he's now learned not only those three family having Sorcery traits but also their contribution to the grail system.

"Nothing important."

"What?"

"Tohsaka provided the land and Servants. Ainsworth offered the Class, Stats, and catalyst. Mato created the Command Seals. And Einzberns establish the vessel. What did the Sayjou family create?"

Kiritsugu pondered for a moment. "What did they create."

"Well," Genmu asked. "What's the first thing you do before summoning a Servant?"

Kiritsugu widened his eyes. "They created the Summoning ritual and Servant limit!"

"Yeah, and their Trait is the passing knowledge to their lineage via blood, and adaptation of miracles and curses. That clan of Witches marrying curse shaman in Japan have practiced to the point that their blood is a potent magical ingredient."

Genmu looked at Kiritsugu before turning the screen and opening a portal to Illya's Realm. "Well Kerry, wasn't That educational."

While both employees walked to the portal, Kiritsugu silently agreed with his friend.

Shiro was actually very important. His daughter was Going to end up with the last descendant of those three awful families!

While he doubted The Market's intention, he was certain of one thing.

When he's gone, Genmu would take over.

Until then, he keeps fighting to give his kids a happy future.

But for now, they just must start with evaluating their performance.

End


Well, two noble line marrying that's beautiful. For the Servant almost everyone will be their but there will be a change. Take a guess PM it and I give a hint. See you later!
