In the end, Kiritsugu couldn't endure it and chose to run away.
Maiya used the tracking skills she learned from Kiritsugu and information gathering to pursue him.
Irisviel used the magecraft she could perform to find Kiritsugu.
He couldn't kill them, and they had become family, but Kiritsugu, who didn't want to be wrung dry, chose to flee.
In the end, to prevent himself from being pounced on by their gazes, he adopted a boy from an orphanage right away.
That boy was Shirou.
It seems his family had died in a murder incident, and he had been living in an orphanage.
I didn't know the original story well, but anyway, since the story of him surviving alone and being saved by Kiritsugu was different, Shirou's Unlimited Blade Works would likely change differently.
Kiritsugu wisely stayed with Shirou, allowing him to survive Irisviel and Maiya.
And Kiritsugu revealed to Shirou that he was a magus, and Shirou began to learn magecraft with an intrigued expression.
After that, Shirou stayed with Lancelot, who became his temporary guardian.
"So what are you going to do?"
"For now, Maiya is pregnant, so it will be difficult."
"Are you bragging?"
Kiritsugu just smiled as if it were a boast.
"It's fine. I'll make sure he can't be with any other woman."
"Iri... anyway, we'll guide you. You can destroy the Einzberns, I don't care. just take care of Illyasviel, my daughter."
"And the reward?"
"Wouldn't Avalon be enough? I don't mean right away, I'll give it to you after I hold onto it for 5 years. If this goes on, I think I'll die."
At those words, I nodded.
"Well, that should be enough."
"Yeah, thanks for helping..."
Irisviel also bowed her head and expressed her gratitude.
"Thanks for helping. If I hadn't been freed from the Grail, I would have been thoroughly broken. I don't know if I'll live longer than Kiritsugu, but anyway, I plan to live with Illya, Kiritsugu, and Maiya from now on. Ah, and with the newly adopted Shirou. If Illya hears she has a younger brother, she'll surely be happy."
'....I think she'll bully him. And a strange switch might turn on... she might open her eyes to the opposite sex early.'
Or she might pounce on him... We had no way of knowing whether Shirou would become a eunuch or a Casanova until we saw the ending.
I was worried about the 5th Holy Grail War that would happen 10 years later.
Even if the flow was different from the original, he was a person qualified to be a Master.
Sakura also seemed to have fallen for Rin, who acted maturely, but the yuri route didn't pop up.
Afterward, there was no more news from Tokiomi, and Aoi didn't seem to break down like in Fate/Zero, perhaps expecting Tokiomi's death. Still, she only smiled for the two girls with a rather pained expression.
Unlike the original story, Aoi shone brightly.
For now, Medea is in charge of magical education.
Rin and Sakura are learning, and Shirou is also learning from Medea.
It wasn't about making them into first-rate Masters, nor was it forced, but they were learning with the will to learn on their own.
Shirou learned the basics of reinforcement magecraft, Rin learned jewel magecraft, and Sakura learned Gandr.
But where did Kariya's presence go? No one looked for him.
He was definitely saved... but he was forgotten.
And so, this trio formed a sister sandwich combination, but Shirou was dense, so it ended with them being childhood friends.
Well, they're still young. Naturally, Shirou was more passionate than expected, and Sakura and Rin fell for Shirou's unyielding attitude, but Sakura sometimes looked at me.
Afterward, Tiamat, Artoria, Diarmuid, and I were dispatched for the Illyasviel rescue plan.
As a result, the Einzbern family, with the will that they couldn't be destroyed like this, handed over Illyasviel and quietly disappeared with the words that they would wait for the next Holy Grail War.
I thought we had reached a happy ending like this. But a few months later, Maiya gave birth to a child, and the child was named Miyu Emiya.
'Now you're going so far as to create Prisma Illya?'
But there is one problem.
Illya, who was supposed to be the Lesser Grail, is not the Lesser Grail.
Considering that, Illya would surely have a top-tier body like Irisviel.
But Miyu is just born, and by 2004, she will surely be an elementary school student.
Then, I wondered how often the switch inside Illya's body would turn on.
For Shirou, I'm 100% sure, but I don't know how Miyu will turn out.
Current situation of Shirou

"Illya nee-san, do I have to wear this?"
"Yes! I think it'll look good on you, Shirou!"
It's been a long time since Illya's switch was flipped.
Seeing Illya dressing Shirou in girl's clothes and savoring the taste, Sakura and Rin shouted.
"Even if he's adopted, if you're Shirou's older sister, no, if you're a big sister, show some sisterly behavior!"
"That's right! Shirou hates it too!"
But unlike her words, Sakura was having a nosebleed.
"Hee~"
And as Illya put a wig with female hair on Shirou.
Rin and Sakura's hearts pounded.
"No way! He's a boy, how can he look like a girl!"
"Rin nee-san... I feel strangely motivated."
"No, Sakura, if you fall, what am I supposed to do!"
"Look! Shirou onii-chan looks better disguised as a girl!"
"No, everyone is treating me like a doll! Medea nee-san, ugh, no, save me, Noona!"
At that sight, Lancelot smiled warmly.
They looked like they were getting along... so he just smiled.
And behind him was a certain King.
"Sir Lancelot? do you think the process of three girls turning a boy into a girl is normal?"
"My King, they were just playing nicely..."
As Lancelot's sins and stigma became increasingly unknown, receiving punishment became a daily routine.
"Useless talk!"
In the end, he couldn't resist and had to be beaten.
Afterward, Shirou survived with Artoria's help, but Artoria also thought Shirou looked good cross-dressing.
If Shirou had been a girl, she would have been pretty enough to bewitch even boys, like a fox.
And so the Holy Grail War ended, and as support from the Grail disappeared, mana consumption doubled, but we got through it as if it were nothing.
Medea succeeded in completely purifying the Grail, and also succeeded in purifying the Grail's materials.
After that, we grasped the Grail's materials and became capable of creating a Grail, but we wouldn't use the Grail for sale.
It was only possible to the extent of incarnating Servants, and with Tiamat's mana support, incarnation was easily possible.
The strange thing was that even after incarnation, they didn't become ordinary humans, but maintained their prime state.
Perhaps it was also due to Tiamat's influence, but in result, you could see them as living Heroic Spirits.
There was also concealment of magecraft, and the protagonists of Fate/stay night were growing up as magi while learning diligently, with 10 years remaining until the original story.
Afterward, Kiritsugu became close with Taiga Fujimura, and his mind was corrupted by Illya.
"I think Shirou should have been born a girl, not a boy! Look at that cute and lovely appearance! Is that the appearance of a boy?"
"Taiga noona... please, stop it."
Shirou's mental state became like glass.
Afterward, Shirou became curious about kendo and made numerous efforts to reach Taiga.
Magecraft was magecraft, but it was impossible to win against Taiga, who wasn't a magus, without using magecraft, but Shirou tried.
He had no talent, but he was a hard worker, and seeing that, Taiga showed an atmosphere of having fallen for Shirou a little.
Shirou Emiya and Illyasviel lived in the Emiya residence, Aoi and Rin lived in the Tohsaka residence, and finally, Sakura lived in my residence, maintaining distance.
Why? Shirou's mental life wouldn't remain, so grouping them together was too cruel a story for Shirou.
On the other hand, Maiya and the newborn Miyu were staying at the Emiya residence, but Kiritsugu and Irisviel were not.
What are those two doing?
Of course, to prevent an affair from happening, they wrung Kiritsugu dry to the level of absorbing his life force.
Kiritsugu was getting thinner and thinner, and he returned to the Emiya residence with an expression that said he couldn't do it anymore, but Miyu turned 4 and was entrusted to Shirou and Illya.
In the process, seeing Illya cross-dressing Shirou, Miyu was mentally corrupted.
"Shirou onii-chan? Girl?"
"Miyu... do you wish I was a girl too?"
Only, Miyu shook her head and denied it.
"No?"
Fortunately, if even Miyu had told Shirou to cross-dress, Shirou's mental state would have ceased to exist.
Later, while playing a game, the bet about how many people would confess if Shirou cross-dressed at school was scrapped within an hour.
Why? Shinji confessed too, but after that, Sakura was on the verge of going berserk, so Rin had to drag Shirou out, and Illyasviel also got goosebumps at the fact that Sakura almost went Alter.
Hearing Sakura say that she felt bad because it felt like worms were crawling next to Shirou, I concluded that it was disgusting for a boy to confess around a Matou or Shirou.
I could deduce that her maternal instinct was quite strong, limited to Shirou.
