Shirou, who returned from the Fairy Kingdom

But if Irisviel were to experience the same thing, Shirou would have to fight cancer for her.

It was late at night when the talks with Machiri ended.

Shirou laid out his bedding on the tatami mat, turned off the light, and lay down.

Staring at the familiar ceiling, the boy murmured to himself.

"How long are you going to keep spying... Come out, you're here, aren't you?"

Upon hearing this, a stunningly beautiful woman, adorned with vibrant, colorful flowers, appeared in the Japanese-style room late at night.

Good evening, my Arthur.

Avalon, a female magician with long hair that shimmered with a dazzling rainbow sheen, sat by the boy's bedside and reached out her hand to his forehead.

Shirou grasped her hand, looking at her with pleading eyes: "Help me, teacher."

As expected, this is the person I trust the most.

If even Lady Avalon couldn't save Irisviel, then Shirou can assert that no one in the world can save her.

"Oh my, Shirou actually asked me for a favor... It hasn't happened since the Holy Grail War ended, has it? I really miss it."

Ms. Avalon said with a cheerful expression, "Irisviel is such an important and special person to Shirou, even I'm a little jealous."

Okay, I'll help, I'll help! My hand hurts so much, it feels like you're going to squeeze it raw!

Shirou immediately released his grip, and the silver-haired sage, tears welling in his eyes, rubbed the back of his hand and murmured, "Sigh, you knew perfectly well that I could never refuse you..."

Shirou quickly got out of bed and sat up straight: "Thank you, teacher."

Ms. Avalon said, "Don't thank me, I couldn't prolong her life either."

All I can do is guide you on your path, Arthur.

"Yes."

Shirou nodded respectfully, and Avalon Shirou spoke with a serious expression.

"I'll tell you one way that can reliably prolong Irisviel's life."

“Let her become a real mother,” Ms. Avalon said.

"As long as Irisviel becomes pregnant and gives birth to the child... she can continue to live as a human being."

--------------

Volume 4, Chapter 167: Shirou, do you even know what filial piety is?

"Hey?"

Shirou was stunned.

What does becoming a mother have to do with extending Irisviel's lifespan?

First, can androids get pregnant naturally?

"Teacher, this is not the time for jokes."

Shirou suppressed his inner dissatisfaction and said.

"I'm not joking, I'm very serious."

Arthur, are you doubting my Grand-rank... highest-level "Clairvoyance"?

As she spoke, the most famous prophet in human history proudly puffed out her perfectly sized breasts.

Shirou sighed and decided to trust her one more time.

"Okay... but could you please explain the connection between the two?"

Why was it that Irisviel's lifespan extended after she became pregnant?

The Flower Magician uttered a sound softly.

"Love."

Shirou was a little dumbfounded: "N-I'm sorry...?"

"The miracle of love can conquer all."

Ms. Avalon stated matter-of-factly, "As an artificial being, Irisviel's short lifespan is a problem that no magic can solve."

If anything could extend the lifespan of an android to the level of an ordinary human, it would be nothing short of a magical miracle.

That's right... love is the greatest miracle in the world.

Whether human, android, or even a wild animal, the miracle shared by all life is maternal love!

If Irisviel could conceive naturally like a human, she could break free from the fate of being an artificial human and gain a lifespan equal to that of a human.

This is not speculation, nor advice, but my prophecy—"

"I'm sorry, it was wrong of me to come to you so seriously to discuss this."

Shirou got up from the tatami mat and decided to go out into the yard for some fresh air.

"Wait, wait a minute! Don't go!"

Lady Avalon rushed up and hugged Shirou's leg.

"Believe me, Arthur! What he said is true!"

Shirou twitched the corner of his mouth and sat back down in his original seat.

"Irisviel is a cyborg, so she can't conceive a human child, right?"

Ms. Avalon said, "Actually, it's possible."

"What?" Shirou looked shocked.

"Although it's a bit late, let me tell you some side stories from the Fourth Holy Grail War."

In Einzbern's original plan, he actually intended to recruit magicians from outside to participate in the battle.

Because they are a race that is not good at fighting, and they messed up the last ceremony.

Then, in this abandoned plan, Irisviel was to act as Einzbern's representative, marry an outside magician, and have a child.

In this way, hired external magicians can also participate in the war as members of the Einzbern family.

"...Why go through all that trouble?"

"On the one hand, they want to use the child to control the magician outside."

The more important reason... of course, was to save face for the founding three families; they were worried that using mercenaries in the war would make Tohsaka and Matou laugh at them.

Shirou nodded in agreement: He had already experienced firsthand how much the Einzberns cared about their reputation and image during his time living in the castle.

"The Einzbern originally planned to hire external magicians to participate in the battle, but the Lesser Grail... Irisviel's Master abilities exceeded everyone's expectations."

Considering the possibility of betrayal from external mages, they ultimately decided to send Irisviel as their Master... but in the end, she was still betrayed by her own people, haha.

Although the plan to find a husband from outside the family was abolished, Irisviel's reproductive function remained intact.

She is capable of mating with humans and reproducing naturally.

Shirou was so shocked that he couldn't speak.

After taking a few seconds to calm himself down, he checked again.

"Can I trust you?"

Ms. Avalon spoke with a smug look on her face.

"No matter how many times, it will be the same answer—please trust me, Arthur."

"ok, I get it."

Shirou sighed.

At this point, we have no choice but to trust the teacher.

Incidentally, Machiri's proposed plan was to "first freeze Irisviel, then repair the Greater Grail of Mount Enzo, deceive the magicians outside into coming to participate in the Fifth Holy Grail War, and then use the Grail to make a wish after winning."

The minor Holy Grail needed in this process can simply be modified by any innocent passerby with magical skills...

Of course, Shirou ruthlessly rejected this proposal.

If he were to commit such an evil deed, he would never be able to face Saber, who had entrusted Irisviel to him.

Irisviel did indeed say that her dream was to "become a mother".

Although we now have Shirou, he's not really a child after all... um.

Shirou: "………………"

Compared to Machiri's aversion, Ms. Avalon's proposal was incredibly simple, practically a freebie.

It could even be said that Irisviel's life could be extended with almost no cost, however—

"What's wrong? Is there any other problem?" Ms. Avalon asked.

"..." Shirou hesitated and shook his head.

The Flower Magician observed the boy's reaction, then suddenly realized something and covered her mouth with a mischievous grin.

"I see, I see... Hehehe, how cute?"

Shirou frowned: "Speak your mind!"

"It's nothing, I was just thinking... boys' possessiveness is really complicated~"

"What are you talking about?"

Ms. Avalon slyly narrowed one eye:

"Arthur, were you just thinking that Irisviel would probably be neglected after she had her own...blood-related child?"

Shirou: "…………!"

The Flower Magician crawled to the boy's side using all four limbs, wiggling her bottom, and placed her hands on Shirou's shoulders.

"Yes, I understand your unease and hesitation, Arthur."

After all, it was because of that child that Irisviel overcame her fate, didn't she?

"A child like Shirou Amamiya (a fake) can't possibly compare to my real son..."

The silver-haired succubus leaned close to Shirou's ear and spoke in a voice only the two of them could hear.

"Let's just forget about it. Let's pretend I never brought up that topic."

Shirou, you don't need to do something so thankless, letting your relationship with Irisviel remain at its most beautiful stage...

Suddenly, a chill crept up Ms. Avalon’s spine.

In the dimly lit room, Shirou gazed at her with amber eyes.

"........."

A bead of cold sweat trickled down Ms. Avalon's forehead: the joke had gone a bit too far.

Shirou would never abandon saving the person most important to him just because his own interests are at risk.

Let alone being neglected—

If making Irisviel forget Shirou's existence could save her, Shirou would surely agree without hesitation.

That's who he is.

"I'm so embarrassed... You're right, teacher, I did feel frustrated for a moment."

Shirou smiled brightly: "But it really was only for a moment."

But upon closer examination, the advantages outweigh the disadvantages...

After Irisviel had her own child, I also gained a lovely younger brother and sister-in-law.

Honestly, I'm already looking forward to it. Raising a child will be tough... I wonder if there's anything I can do to help.

Shirou made up his mind and said, "Yes, let's do as you say."

I'll talk to Irisviel about this tomorrow.

Then there's only one question left.
