In this crossover anime, Yoshikage Kira longs for a peaceful life.

He placed a prepared road sign from the trunk on the side of the road, and then got back into the car.

He lit a cigarette, but didn't start the car immediately; the distant castle gradually stirred his memories.

Since being hired by the Einzbern Castle, he was prepared to spend the next nine years there. To obtain the Holy Grail and realize his ideals, Kiritsugu Emiya was willing to endure loneliness.

However, the Einzbern family did not confine him in the castle; instead, they generously allowed him to leave the barrier.

This was completely beyond Kiritsugu Emiya's expectations.

However, although his freedom was not restricted, there were some treaties that limited his movements.

For example, he must return to Einzbern once a month, otherwise the Einzbern family will assume that he has met with misfortune and choose a new magician to replace him.

For example, every time he returns, he needs to put up two road signs with the time written on them.

One piece inside the barrier, and one piece outside the barrier.

Kiritsugu Emiya could completely understand this, since the Einzbern family couldn't allow a dead person to participate in the Holy Grail War in their place.

And today happens to be the day he returns to Einzbern.

However, when he arrived at the castle, he was not greeted by maids as he had been on previous occasions.

This puzzled Kiritsugu Emiya, who wandered around the castle for ten minutes before finally encountering a passing maid.

"Has something happened?"

Emiya Kiritsugu stopped the maid and asked.

"Lord Emiya."

The maid bowed respectfully and explained:

"The lady is about to give birth, and the maids of the Einzbern family are all busy preparing for it."

"lady?"

Kiritsugu Emiya's eyes widened in realization; he knew who the lady the maid was referring to was.

That was the homunculus who accompanied Ahadeon when they first met.

That was his only meeting with Ahadeon, and from then on, Lady Irisviel and her husband were responsible for negotiating with him.

Their explanation was that Arhadon's time had come, and the Einzbern family would be temporarily managed by Irisviel. Kiritsugu Emiya didn't doubt this much, after all, he knew that homunculus lifespans were short.

Even today, Kiritsugu Emiya still finds it strange.

Although he knew that Einzbern's artificial human technology was unparalleled, he still couldn't understand why artificial humans could get pregnant. Aren't artificial humans all produced from culture tanks?

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

Outside the window, snow piled up in the cold wind; in the frigid night, the forest floor was frozen.

In the ancient castle built on frozen soil, the small rooms are protected by warm fireplaces, far from all the cold outside.

"Kira-kun, would you like to hug her? Hug our daughter."

The pure white-clad girl lay on the bed, smiling as she watched Yoshikage Kira pick up the child.

"so good."

Yukino murmured to herself.

"Eh~ Is Yukino envious?"

Yang asked with a smile.

"Ah, I'm so envious."

Yukino Yukinoshita readily admitted it.

Yang clicked her tongue in disappointment. Yukino's honesty actually made her feel no sense of accomplishment at all!

"Kira-kun, please name our daughter."

The young girl's face showed signs of postpartum exhaustion, her pale face devoid of any color, yet this did not diminish her noble, jewel-like beauty.

Because the smile on her face and the glow in her eyes were radiant with happiness, all of this was enough to offset the slight weight loss caused by exhaustion.

“Ilya.”

Kira Yoshikage held the delicate little life in his arms, his eyes filled with unprecedented tenderness, "Illyasviel von Einzbern."

"Is it really okay not to take Kira-kun's surname?"

Irisviel looked up with some concern.

"It's okay, your name is more beautiful, I prefer this name."

Kira Yoshikage gently comforted her, and a happy smile appeared on the girl's face.

She loved hearing him compliment her, whether it was about her name, her great body, or her beautiful hands.

She loved hearing any praise from him.

She had always thought she was destined to be without happiness, and never imagined that anyone could bring her the feeling of 'happiness'.

As an artificial being, this was only natural, and Irisviel herself never expected anything.

She was created like a doll and grew up like a doll, and she didn't even understand what 'happiness' really meant before.

And now, she is smiling brightly.

"It's so wonderful to have met you and to have this child."

Calmly and lovingly, Irisviel von Einzbern said this as she looked at the sleeping baby.

Boom!

The maid knocked on the door and entered the room, saying respectfully:

"Madam, Master Yoshikage, Mr. Emiya has returned."

"Yukino."

Kira Yoshikage's expression shifted slightly, and he called out the girl's name in a low voice. She nodded gently and left the room with him.

Yukinoshita complained:

"Really, what's the rush?"

It's his wife who's pregnant, can't he take better care of her?

Irisviel smiled gently:

"It's okay, Haruno. As long as he loves me, that's enough."

Yukinoshita commented:

"You're being too magnanimous; you'll be bullied your whole life!"

"Shouldn't a wife unconditionally support her husband?"

Irisviel continued to smile and stand by her convictions.

"That's really why I feel lonely."

Yukino complained that it wasn't just a matter of lifespan, but also that her views were completely different from everyone else's—sometimes she even felt that she was the only normal person here, and that everyone else, including Yoshikage Kira and Yukino, were all a little off!

Especially Irisviel.

How could a wife as perfect as her, like something out of a fantasy, possibly exist in reality?

"Alice, let me see her."

Despite inwardly complaining, Yono excitedly moved closer to the bedside and reached out to touch the cheek of the little life in Irisviel's arms.

Her small mouth opened and closed slightly, her breathing weak and labored, trying to maintain a little body temperature while she slept. A faint, desperate heartbeat could be heard from her chest.

"Ahhh, she's so cute!"

Yukino's heart almost melted. What happened to the fact that newborn babies are all wrinkled?

Are the children born from cyborgs so different?

Damn it!

She suddenly understood Yukino's feelings; she also really wanted to have a child!

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

The inner edge of the Einzbern Castle barrier.

Yukino Yukinoshita and Yoshikage Kira stood by the roadside, with a row of road signs on the right.

Those were the signs that Kiritsugu Emiya had checked; each sign recorded the time he returned here.

Yukino Yukinoshita said softly:

"Kira-kun, let's begin."

Yoshikage Kira took the girl's hand and gently kissed it:

Be careful and stay safe.

She had actually lied to her sister.

She previously said there was no way to safely leave this barrier, but actually there is.

Kira-kun possesses the ability to rewind time.

By using Bites the Dust on them, even if they fall into the vortex of history and cannot return when they leave, they can return to the time when they were still in Einzbern by constantly rewinding time.

However, this ability has significant limitations; for example, it can only be used three times a day.

In other words, you can only leave the barrier for a maximum of three hours.

Only within three hours can they be guaranteed to return to the barrier after three rewinds. Otherwise, if this limit is exceeded, they will also be trapped in the vortex of time.

"call."

The girl bearing the Bite of the Dust curse stepped out of the barrier and looked toward the roadside.

There were at least fifty road signs neatly arranged there, and the newest one had the date written on it:

1990 1 Month 7 Day.

"really."
