Shirou, who returned from the Fairy Kingdom

When Matou Zouken, growing impatient, took the initiative to approach her.

"Didn't I tell you to come find me right away?"

"I'm sorry... Grandpa, I'm coming right now."

Matou Sakura quickly lowered her head and followed the old man's steps.

It's a real shame, it looks like I won't be able to talk to Shirou-nii tonight.

Volume 1, Chapter 008: Projection Begins

"Shirou~ Is he still awake~?"

Around 8 PM, the wild Matou Shinji appeared.

"You're not asleep? What's wrong?"

Shirou, who had been lying on the bed with his legs crossed, sat up while staring at the ceiling.

"Come and see this."

Shinji handed a Walkman to Shirou.

"Tsk, showing off again?"

Shirou felt that this kid was starting to resemble a character from the sci-fi anime he had been watching recently.

I think his name was "Xiaofu".

Shinji shook his head: "I'm not showing off, this seems to be broken."

"Oh."

Shirou took the Sony Walkman and examined it closely.

Shinji sat down beside him: "How is it? Can it be fixed?"

Shirou frowned slightly: "Hey, what exactly do you take me for?"

Do you think I'm Doraemon?

"Can't it be fixed?" Shinji asked dejectedly.

"I didn't say it couldn't be fixed."

After Shirou said that, Shinji Matou's eyes immediately lit up.

"Wow, that's amazing! I'll leave it to you then, Shirou!"

"Stop talking nonsense, don't stand so close, it's so hot, move over to the side."

Shiro touched the damaged plastic product with his finger.

Walkman

Britain clearly lacked similar technology and creations; this was Shirou's first encounter with such sophisticated machinery.

However, not having seen it doesn't mean it can't be fixed.

Even professional technicians struggle to solve problems, but magicians can easily fix them.

Shirou Amamiya closed his eyes, used his sense of touch to feel the inside of the Walkman, read its internal structure, and drew a design diagram.

I remember when I first explained this technology to Morgan, the fairy in the park stared wide-eyed.

"Of course Morgan could do that too, right?"

"How...how could that possibly be possible!"

It seems that this is an extremely rare talent unique to Shirou, something that even the omnipotent and invincible genius witch cannot achieve.

Morgan smiled and said, "So from now on, the maintenance of the team's weapons and equipment will be handled by Shirou."

That guy, he probably lied to me so I'd do some work, right? He doesn't actually have any rare talent at all!

Well, thanks to this talent for deconstruction, Shirou was able to develop a series of fighting styles later on.

For example, because Shirou possesses the origin of the "sword," he can analyze and store all the prototypes (swords) he has ever seen in his body, and then copy them out when needed.

However, for now, all he can do is find the fault in the Walkman and fix it.

By the way, how about I open a car repair shop instead of becoming a chef in the future?

Lost in thought, Shirou fixed his Walkman.

"Shinji, it's all done."

Shirou turned around and found that Shinji was not beside him at all, but was lying on the windowsill in a daze.

Children of this age have very poor concentration; they can't wait even a short while.

The boy, gazing at the city lights, murmured to himself, "Sakura is so cute... her quiet, obedient demeanor is just like a doll~"

"Why are you suddenly saying this?"

Shinji turned around, clenched his fist, and said, "Shirou, I've decided. I want to become a brother that Sakura respects!"

"Really? Good luck then... Here, don't break it again."

Shirou shoved the Walkman into his arms.

"Oh, it's actually fixed. As expected of Shirou."

Shinji excitedly held his Walkman, shouting, "I'll treat you to Ramune soda tomorrow!"

Shirou stood up from the bedside: "It's easy to fix machines, but when a person breaks down, it's not so easy to fix them."

"What is that? Something a famous person in history said?" The seaweed boy blinked.

Shinji Matou said he wanted to become an excellent older brother, and his words were clearly from the bottom of his heart, without any falsehood.

However, Shirou did not believe that it was something that could be done easily.

The seven-year-old boy was completely unaware that his position within the Matou family had subtly changed due to Sakura's arrival.

Shinji, sensitive and with a strong sense of pride, discovers that he is actually superfluous in his family, and that his younger sister, whom he wants to protect, is the family's hope—

How exactly will one's mindset change?

Good luck, Shinji, but I'm not going to help you.

The boy with seaweed looked towards the door: "It's so late, where are you going?"

Shirou waved his hand with his back to him.

"Don't follow me when you're peeing."

……

……

Sakura Matou's training grounds are located in the basement of the mansion.

After passing through layers upon layers of solid, airtight magical barriers, one arrives at the workshop that Zouken Matou is so proud of.

A putrid stench permeated the air, a green darkness like the deep sea.

Looking at the hellish scene before her eyes, Matou Sakura covered her nose, her pupils trembling.

"Grandpa, where is this place... what are these insects?"

A few meters in front of the girl was a huge crater.

In the abyss, countless dark shadows lurked.

It was an insect with an extremely ugly appearance and sucker-like mouthparts.

Covered in slime, they clump together like a black, velvety carpet.

These are the lewd insects raised by Zouken Matou—demons that crave human bodily fluids, brain marrow, and bone marrow.

If a man is possessed by a lewd insect, his spine will be shattered, his brain drained, and he will become a complete cripple.

If it's a woman—the insects will choose to parasitize her body, control her nerves, and turn her into a beast that craves vaginal fluid.

As a result, the woman who was possessed by the insects had her body and mind completely violated and destroyed.

In order to transform the Tohsaka family's daughter into someone more suited to the nature of Matou magic, physical modification is necessary.

So, let's get started.

"...Grandpa, no."

After listening to Zouken Matou's explanation, the girl's eyes filled with tears, and she let out a desperate, hoarse voice.

"If you have any resentment, blame your father who sent you here... By the way, isn't Tokiomi no longer your father?"

The old magician chuckled and came to the girl's side.

"Go, go and become the real Matou Sakura."

"don't want!!!"

The girl screamed, her legs gave way, and she collapsed to the ground.

"Oh dear, oh dear... Sakura, you can't do this. Don't make things too difficult for this old man."

"No, no, no... Ah—!!!"

Zouken Matou went over, grabbed her hair, and dragged her to the edge of the pit in one go.

Just as he was about to throw Matou Sakura down,

"——————Projection, begin (Trace on)."

Accompanied by a deep, youthful voice, the first flame ignited in the dark, shadowless world of insects.

"What... Ughhhhhh!"

Zouken Matou turned around, but the dazzling light from the burst of flames blinded him, a stark contrast to his usual accustomed darkness.

“W-What is that!?”

He screamed in pain and subconsciously.

"You're asking about what I'm holding? Ah, their name is..."

Shirou Amamiya raised his arm, which was tightly bound by chains, and looked nostalgically at his two beloved swords, one on his left and one on his right.

"Blades of Chaos."

Volume 1, Chapter 9: I Am Sword Bones

The blazing fire that had illuminated the darkness gradually subsided, and Zouken Matou quickly regained his sight.

He clearly saw the intruder in this magical ritual.

Calling them intruders is not accurate, as they were guests who had been invited to stay at the Matou residence.

Amamiya Shirou.

Zouken Matou was greatly surprised.

How can this be! !

Someone actually infiltrated Matou's workshop and the realm of magic, yet he himself was completely unaware of it?

Although he has long passed his peak, he remains one of the country's best magicians.

Especially in the realm of curses, there are very few magicians who can compare to Zouken Matou.

The workshop was surrounded by dozens of protective barriers and curses, and a large swarm of winged blade insects was deployed for reconnaissance and defense.

For Zouken Matou, the winged blade insect is part of his sense of touch. Even a slight breeze in the underground passage should be something he can feel, let alone a living person.

How could I have made him silently come up behind me?

More intriguing than that is Shirou's appearance.

Chains wrapped around the red-haired boy's slender arms, even embedding themselves into his soft skin.

In the small hands of the red-haired boy were two blazing scimitars, their inextinguishable flames illuminating the dark hell of insects.
