Shirou, who returned from the Fairy Kingdom

"No, it was just because I drank too much."

Shirou: "…………"

But is it possible to get a result after only one month of pregnancy?

Shirou looked at Irisviel's abdomen, which, of course... couldn't possibly be moving at all.

The android maid continued to explain, "Pregnancy tests can indeed detect pregnancy as early as one month into the pregnancy."

Irisviel touched her cheek, embarrassed, and said, "Actually, from that night on, my first time with Shirou..."

From our very first night together, I've been taking a pregnancy test every single day.

Then, during the routine test tonight, we found different results.

"I see. You've been testing for a whole month now..."

"Yes, it is."

Seeing Irisviel's shy expression, Shirou was speechless.

This also means that she really wanted to have a child.

In fact, every night when she received Shirou's seed, Irisviel would repeatedly ask questions like, "Will this make me pregnant?", "Should we tape it off? Are you sure we don't need to?", and "Should we do it a few more times tonight?"

"If we calculate it that way, fertilization and implantation should have occurred on the first night."

"Oh, is that so?"

"From a time perspective, that should be correct."

"So, Shirou and I get along really well...?"

Shirou and Irisviel exchanged a glance, then both lowered their heads in embarrassment.

"Shirou, do you want to touch it?"

"May I?"

"Of course you can, because this is your child."

Shirou held his breath and reached his trembling hand toward Irisviel's abdomen.

Of course, there were no ups and downs.

If it's only one month into the pregnancy, this is perfectly normal.

But why...? Shirou wants to keep touching her like this forever.

"...Ahem."

Sera's clear cough made Shirou quickly withdraw his hand.

"Shirou, please don't forget, all of this is to prolong Lady Irisviel's life."

"Of course I know! Even if you don't say it, I understand. Sera, why are you always going against me today?"

Shirou said with dissatisfaction.

"...Pfft."

Watching the two arguing, Irisviel covered her mouth and chuckled.

She reached out and stroked Shirou's hair, saying softly:

"Then please take good care of this child from now on, 'older brother'."

"………………ah."

Shirou suddenly snapped out of his dreamlike bliss.

By the way, I can't be the child's father.

After all, Shirou Amamiya is still a 0-year-old student...

Shirou's only identity can be that of the "adopted brother" of the child in her womb.

This was a decision he and Irisviel made after discussing it for a long time.

Shirou only provided the genetic material; Irisviel did not want him to bear the responsibility.

This is only one aspect; more importantly—

If you want to protect the "Amamiya family" and their place of refuge, this is the only way.

"........."

"What's wrong, Shirou?"

"No, it's nothing."

"Really, that's not an expression that says 'nothing'."

Irisviel opened her arms and gently embraced Shirou.

"Don't worry, Shirou... I'll explain it to her when she's a little older."

The truth about who the real father is will be revealed in detail...

Shirou, just bear with it until then.

"I understand, okay."

Shirou nestled his face against Irisviel's chest and closed his eyes.

at this time--

"Clap."

A strange noise came from outside the door.

"!!!"

Shirou jolted awake and looked up to meet Irisviel's gaze.

—Someone was outside, and our conversation was overheard!

"........."

Shirou stood up, walked silently to the door, and then suddenly pulled it open.

There's nobody outside.

No, they must have escaped.

"Shirou, what should we do?"

Irisviel looked at him for help, and Shirou reassured her, "It's okay, leave it to me," before leaving the room.

Shirou walked briskly along the corridor in the night.

Who was eavesdropping outside the door just now?

Ryudou Kazunari has already gone back; the guests who are still staying at the Amamiya residence...

Sakura Matou, Shinji Matou, Rin Tohsaka, Ayako Misaki, and Taiga Fujimura are among the five.

Sister Teng isn't the kind of person who would silently eavesdrop outside the door and then run away... No, wait.

Shirou and Irisviel have a secret relationship; they even had a child together.

Even with Sister Teng's strong mental fortitude, she would probably want to run away after hearing that!

Shirou returned to the living room as quickly as possible.

"Oh! Shirou, you're back! Why did it take you so long?"

"What about the rest?"

Shirou was taken aback, as there was only Shinji Matou in the living room.

"Hmm? Sakura and the others went to the restroom together."

Okay, Shinji is out of the running, so the pool is narrowed down to the four women.

After that, by subtly inquiring with each person, it will be possible to find out who was eavesdropping outside the door.

However, if we consider that there were two or more people eavesdropping outside the door at the time, then there is also the possibility of collusion.

If it had been Rin Tohsaka outside the door at that time, she could have used suggestive magic to get someone else to give false testimony for her.

As for Matou Sakura, while she can't use suggestion magic on Rin, she can easily handle Fujiwara and Ayako. And Rin is a die-hard siscon who will protect her younger sister...

Shirou returned to Irisviel's room and reported the incident to her.

I meant to reassure her, but this was the response I received.

"Let it go, Shirou... let's not dwell on who was outside at the time."

"Why?"

"Taiga and the others, they're not the kind of girls who would go around telling everyone Shirou's secrets, are they?"

"That's true, but just in case..."

"That's enough. I believe they won't do anything to harm Shirou, so there's no need to pursue this any further."

Irisviel stroked her unchanged belly and said, "I don't want you, Shirou, to hurt your friend because of this child. Am I wrong?"

"Since you put it that way, Alice, I understand..."

Shirou nodded, agreeing with Irisviel's words.

Let's just let this matter go for the sake of our unborn child.

"Instead of that, Shirou! I've already thought of a name, okay?"

Although Irisviel possesses the same reproductive ability as human women, her uterus seems only capable of giving birth to women—

After all, from the very beginning, Irisviel's fertility was a strategic consideration for "creating the next Little Grail".

So even though it's only a one-month-old embryo, it's already certain that it will be a girl with beautiful silver hair and red eyes.

Because the Einzbern traits are maxed out, it's a bit of a shame that Shirou's characteristics can't be inherited...

"Ideally, she would be a cute girl with a 'baby face' like her father," Shirou thought.

What name are you planning to give it?

"Illya Amamiya".

"what?"

"Just kidding, haha... Sorry, this child's surname should be Einzbern."

Irisviel smiled and said, "Her name will be 'Illyasviel'."

“Ilya…Sfiel…”

Shirou kept chewing on the name.

Ilya.

For some reason, a strange feeling of emotion welled up in his chest.

"Alright, let's go. If we leave for too long, they might get suspicious."

"makes sense."

Shirou and Irisviel returned to the living room, and the group of girls who had gone to the restroom together returned around the same time.

Although he no longer intended to pursue the matter, Shirou was still very curious about what exactly he had been eavesdropping on.

After carefully observing the faces of the four women, I couldn't find anything unusual.

After that, the welcome party for the evening officially came to an end.

Fujimura Taiga rarely returns to Fuyuki, so he'll have to show his face at the group tonight; he'll probably be spending the night there.

The remaining three girls seemed to have planned to stay overnight at Mitsuko's house, but only Shinji went home...

Shinji expressed his desire to stay overnight at Shirou's place, but the girls scolded him for just returning from abroad and for causing trouble for him. In the end, he could only leave dejectedly.

Sorry, Shinji... I don't have time to play games with you tonight...

I'm going to be a father soon, after all.

Shirou felt that a pitifully thick barrier had already separated him from Shinji.
