Shirou, who returned from the Fairy Kingdom

"Grandpa?" Shinji blinked.

Shirou replied in a flat tone, "Of course not, Shinji is my friend."

Zouken Matou said, "Is that so... I'm truly sorry for what happened earlier. I was rude and treated my guest so impolitely."

"Ah, Tsuruno has already agreed to let you stay, right? You can stay as long as you like, no need to worry about me."

Shirou asked, "Does the old man live here too?"

Zouken Matou said, "Yes, but as you can see, it's already a rotten shell. It can only wait to die quietly deep in the mansion, day after day."

"...Then please excuse me, Shirou Amamiya. Please get along well with my grandson."

The old man disappeared briskly into the darkness of the corridor.

The Matou Residence has returned to tranquility.

Not only the sounds of conversation, but even the tranquil chirping of insects ceased.

"Hey, Shinji, your grandfather—"

Shirou looked at the boy with seaweed next to him and found him looking moved, with tears welling up in his eyes.

"Shirou... is my friend... Waaah..."

……

……

"clairvoyance".

Unlike the magic eye, which is more of a magical application, it is a latent ability that the human body is born with.

Throughout history, many great warriors who have left their mark on history possessed "clairvoyance"—

The low-level "clairvoyance" possesses powerful static, dynamic, and long-distance vision, but it is an ability limited to combat.

Shirou Amamiya also possesses the aptitude of "clairvoyance," and the level of his twin eagle eyes is C... that's how it should be.

But in another Britain, Shirou faces betrayal, deception, malice, and the like from fairies every day... His eyesight has been honed to a level unimaginable in the history of humankind.

With the addition of a certain genius witch's magical modifications, this is the final result.

"The Demonic Eye of End".

Shirou Amamiya's eyes can trace back to the source, all the way to the "end" of cause and effect—that is, the "origin" of all things.

In Shirou's opinion, the world's assessment of Shinji's grandfather as a "vampire" might actually be accurate.

Despite its aged appearance, its internal decay is far more severe.

Normally, it would be normal for it to break down, but this old man remained rational.

It decays and deteriorates with each reincarnation, yet it still retains its capacity for thought.

What kind of powerful obsession could lead someone to this level?

Does he still remember his original "purpose"?

"Humans are truly incredible..."

As Amamiya Shirou thought this, he sank his head into the soft, unfamiliar pillow.

He has now found a place to stay, but the road ahead remains uncertain.

Where to go next?

What is the "purpose" of this human, Shirou Amamiya?

Looking out at the familiar yet unfamiliar starry sky, Shirou suddenly felt a little lonely.

"Dong dong dong."

There was a knock on the door.

"Shirou! Are you still awake?"

"Not sleeping yet."

Upon hearing this, Shinji Matou pushed open the door and entered.

"what is that?"

Shirou noticed that the wakame boy was holding a brick-shaped object triumphantly.

"I just bought a new game console, do you want to play?"

"Bring it to you."

Shirou got out of bed and snatched the toy from Shin's hands.

Well... before deciding on my future, I'll enjoy this rare second childhood first.

……

……

And so, I spent a week at the Matou family's house.

Although it's not in Amamiya Shirou's style to eat and drink for free at someone else's house and not do any housework, the Game Boy is just too fun.

A terrifying human civilization!

One morning, Shinji suddenly rushed excitedly into his room.

"Shirou! Shirou! Wake up!"

"Hmm? Let me sleep a little longer, don't make a sound."

Shirou buried his head in the blanket.

He stayed up until 4 a.m. last night.

Shinji, meanwhile, was pulling at the blanket while shouting excitedly.

"Shirou! Get up! I'm going to have a little sister!"

"No, what does this have to do with me..."

Volume 1, Chapter 5: Matou Sakura

Shinji Matou's new younger sister's name is Sakura.

She is not Shinji's biological sister, but was adopted from another family.

The family that sent their daughter away was the Tohsaka family, located on the mountaintop. It seems that Tohsaka and Matou have been family friends for many generations.

At that moment, Shinji Matou knelt outside the living room, observing the situation inside through the crack in the door.

"Come and see, Shirou... That's the second daughter of the Tohsaka family, she'll be my little sister from now on!"

He tugged at the boy's sleeve, and Shirou peeked through the crack in the door with great impatience.

There were four people in the room.

Sitting on the sofa is Zouken Matou.

Matou Tsuruno stood respectfully behind him like a secretary.

When Shirou first moved in, he realized that Tsuruno's position as head of the family was just a facade, and that Zouken was the real head of the family.

　"And then, sitting opposite Zouken is..."

A middle-aged gentleman, dressed in fine clothes, with elegant manners and a goatee, was talking to Zang Yan.

"That's Tokiomi Tohsaka, the current head of the Tohsaka family."

Shinji explained it in a friendly manner.

"And sitting next to him is Tohsaka Sakura... no, she should be called Matou Sakura now!"

The boy, hiding furtively behind the door, grinned foolishly with a happy expression.

Is having a younger sister really something to be so happy about? Shirou is an orphan, so he doesn't quite understand.

Although the fairies of "Britain" cannot reproduce, they do form families.

The family was not bound by blood ties, but by "duty." Morgan was raised as a daughter by other fairies.

Looking at Shinji's smiling face, Shirou suddenly felt a little annoyed and kicked him in the butt.

"Ahh...ah!?"

Shinji stumbled forward, crashing through the half-closed door before falling face-first to the ground.

"Then, I'll leave Sakura in your care..."

Tokiomi Tohsaka and Zouken Matou stopped talking, and the four people in the room all looked towards the door.

Shinji! What are you doing there?!

Matou Tsuruno's roar echoed in the living room.

Shinji Matou was terrified and lay on the ground, gesturing wildly as he tried to explain:

"No...no, Dad...this is...this is Shirou..."

"This must be Shinji-kun. He's grown up so much in the years we haven't seen him."

Tokiomi Tohsaka smiled as he looked at the boy who had interrupted their conversation.

"Hey, this is the unworthy son, Matou Shinji."

Matou Tsuruno lowered his head apologetically and said, "His mother died early, which is why he has always been so mischievous. I'm really sorry."

"It's nothing, children this age should be more lively."

Although it was very subtle, Shirou still noticed the disdain and contempt that flashed in Tokiomi Tohsaka's eyes when he looked at Shinji.

The gentleman patted the girl's head and said, "Sakura, go and say hello to your future brother."

"Yes."

Tohsaka—no, Matou Sakura—jumped off the sofa, walked up to Shinji, and obediently bent down.

"Brother, please guide me in the future."

"Oh, oh! Please take care of me from now on, Sakura~"

Shinji Matou lay on the ground, grinning foolishly.

This guy doesn't seem to realize that after Tokiomi leaves, he'll get a good beating from his father.

Matou Sakura then looked at Amamiya Shirou beside her and bowed again: "Brother, please take care of me from now on."

No, no, no, I'm not your brother.

Shirou thought to himself: If we count by real age, I could be your grandfather.

Tokiomi Tohsaka also noticed the red-haired boy and asked curiously, "Old man Zouken, who is this...?"

“He’s Shinji’s friend. He’s been staying at my house recently… well, he’s a slightly precocious and strange kid.”

Tokiomi Tohsaka's attention didn't linger on Shirou for long before turning back to the adults.

"Then, I'll leave Sakura's matter to you."

"Hehehe, leave it to me." Zouken Matou said in a cheerful tone.

Tokiomi Tohsaka called his young daughter to him again, gracefully knelt down on one knee and placed his hand on her shoulder.

"Sakura, from today onwards, you are a child of the Matou family. You must listen to your grandfather, understand?"

"Yes, Father... Uncle Tohsaka."

Seeing Matou Sakura nod obediently, Tohsaka Tokiomi also nodded in satisfaction.

"Always maintain elegance, no matter when or where," is a family motto passed down through generations of the Tohsaka family.

Sakura was separated from her parents before she was seven years old and sent to a stranger's home. Even so, she didn't cry or make a fuss and quietly accepted everything.

This undoubtedly stems from his successful education, something Tokiomi Tohsaka is extremely proud of.

"Then I'll take my leave now."
