The Nuclear Sword Fairy from a certain cartoon

Suddenly, the sound of the system came.

[You have been given an opportunity to open the dimensional roulette, do you want to use it? ]

"Dimensional roulette? What is that?"

Shirou asked a little confused.

[Through the dimensional roulette, you can randomly obtain an ability, bloodline or prop...]

[Complete the main quest "Winning the Holy Grail"

War" to get another chance to open the dimensional roulette. ]

Shirou's eyes suddenly lit up when he heard this.

"Is that so...then turn it on!"

Following Shirou's words, the familiar translucent panel appeared in front of him again.

A roulette wheel appeared on that panel, showing abilities, props, and bloodlines from various worlds.

"Come on, see what you can bring me..."

As Shirou muttered like this, his eyes reflected the spinning roulette wheel.

【You have obtained a "Blank Class Card"! 】

"This is……?"

Shirou clicked on the description of this item with some confusion.

["Blank Class Card": Can connect to the Heroic Spirit Seat and obtain the matching heroic spirit power. 】

"Is that so... Although the description is a bit vague, won't you know if you try it?"

There is no way out.

With a thought, a card appeared in Shirou's hand.

The card was golden in color, with a special pattern on the back, like a magician wearing a cloak, while the front was blank without any patterns.

"connect……"

Shirou's voice transcended the limitations of time and space and turned into an invisible thread, connecting him with the Heroic Soul Seat.

It was like the soul leaving the body, an unprecedented experience, and countless scenes appeared in front of Shirou's eyes.

Figures of heroic spirits flashed before his eyes, but no one was willing to establish contact with him.

However, there is an exception to this.

It was a vague red figure.

His voice appeared in Shirou's ears.

"It's actually you... it's incredible..."

That person's voice made Shirou feel a sense of intimacy just by hearing it.

This is the heroic spirit Emiya from the future of a certain timeline.

"So...if this power is passed on to you, what are you going to do?"

"guard!"

Hearing that question, Shirou answered without hesitation.

"I want to be a righteous partner who protects my family!"

The word "family" caused the voice from the Heroic Soul Seat to suddenly stop.

After a brief silence, wanton laughter broke out.

His words were mixed with laughter that seemed to be self-deprecating.

"If you can really change all of this and protect all of this... then take it! Take it all!"

moment----

The power of the heroic spirit is transmitted to Shirou through the invisible "thread".

The blue magic power traveled wildly through his body like lightning.

Light flickered in the dim room, flickering on and off.

The magic power increased at an unimaginable speed, and the silent magic circuits in Shirou's body continued to open.

1...

2...

10...

17...

27...

The pain, as if his blood vessels were being shocked by electricity, made him grit his teeth.

In his almost blurry consciousness, Shirou had hallucinations before his eyes.

It was an endless wasteland.

Picture: "Heartscape", location: "Images/1672625160-100352746-109768307.jpg"

Countless swords were stuck on the endless wilderness, and the gentle breeze that blew by blew Shirou's red hair, but no sand and dust flew up.

The clouds in the sky are constantly changing, as if time is passing rapidly. The orange sunlight shines brightly on the obscured clouds, and light particles seem to be floating in the beams of light passing through the clouds.

Standing in this world, Shirou felt as if he was soaking in a hot spring, feeling extremely warm and comfortable, peaceful and relaxed.

The hallucination did not last long. As consciousness gradually returned, the wasteland gradually disappeared and returned to the dark and silent room scene.

At the same time, the "Blank Class Card" held by Shirou had turned into golden fragments and dissipated in his hand.

When everything fell silent, Shirou Orihara's 7-year-old boy received the power of a heroic spirit inconceivably.

Chapter 3 Unlimited Swordsmanship

"This is... the power of a heroic spirit!"

Shirou quickly focused his attention on the white dot in the lower right corner of his sight and opened the properties panel.

The next moment, a translucent panel appeared in front of you.

[Name: Orihara Shirou]

【Sex: Male】

【Age: 7 years old】

【Height: 134cm】

【Race: Human】

[Bloodline: None]

[Special ability: "Unlimited sword control"]

【肉体强度：6→240（10）神经反射：7→361（10）生命力：6→334（10）精神力：27→137（10）】

Looking at the panel that appeared in front of him, Shirou raised his right hand and held it tightly.

"I don't know if I can fight against other heroic spirits now..."

Normally, the servants summoned by humans are just clones of the heroic spirit's body.

However, the servants summoned in Fuyuki City were able to copy all the personalities and powers of the corresponding heroic spirits thanks to the power of the Holy Grail.

Among these, Saber, who appeared in her true form, is probably the only exception.

Although he possesses the power of heroic spirits, Shirou also understands that except for Assassin, it is basically difficult for him to win in a head-on battle.

In addition, his inherent barrier is different from that of the future heroic spirit Emiya in that world line.

The inherent barrier is a magic that embodies the mental landscape, and the space inside will naturally change according to the artist's heart.

Therefore, Shirou's mental landscape is naturally different from that of the future Heroic Spirit Emiya.

The sword that was not in the memory did not appear in that mental landscape.

What appeared inside were the Noble Phantasms that were impressive in Shirou's memory.

For example, "Gan Jiang Moye", "Pseudo Spiral Sword", etc...

"But it doesn't matter. As long as I can see the prototype, I can basically analyze and copy any Noble Phantasm below the EX level except divine weapons."

And in this Holy Grail War, isn't there a heroic spirit who possesses the prototypes of all Noble Phantasms?

But in this case, it would have to involve something that Shirou didn't want to think about before.

"Participate in the Holy Grail War..."

In the past, Shirou never thought about this matter because he had no power.

But now, Shirou, who has extremely clear memories of the time before his death, has come to his senses.

Not only to protect the people he wants to protect, but also to become stronger, Shirou is determined to enter this Holy Grail War.

At the moment when he was making up his mind, Shirou suddenly felt the back of his right hand was itchy and couldn't help but lift it up and take a look.

On the back of the raised right hand, scarlet lines began to appear and take shape.

Image: "Command Seal", Location: "Images/1672626404-100352746-109768308.jpg"

"This is... the stigmata?"

The so-called stigmata is a magic crystal that appears on the back of the hand or wrist. It is also the exclusive mark of magicians who participated in the Holy Grail War.

The Holy Grail will give qualified magicians some omens, that is, marks such as stigmata. When the magician completes the summoning ceremony of the servant, this mark will be converted into a command spell.

Looking at the stigmata on the back of his hand, Shirou couldn't help but his eyes brightened.

"In this way, I can just add a helper."

With this murmur, Shirou left home without any further hesitation.

……

The time has reached one o'clock in the morning.

The hazy clouds and mist blocked the bright moonlight, casting a gray light.

The empty city streets are dazzling by neon lights and the lights are blurry, both illusory and real.

Shirou came to the Citizen's Park by the river alone.

The quiet late-night park is reminiscent of a cemetery.

In the empty square, the dim lights of the street lamps set off the darkness and silence a bit terrifying.

The night air in Fuyuki City has obviously deteriorated, and Shirou can now notice this.

The Holy Grail War has quietly begun.

"Let's do the summoning right here."

After choosing a location, Shirou took out the prepared materials and began to arrange the summoning ceremony.

"First, draw the pattern of the magic array on the ground."

Shirou projected a sword and began to draw a magic circle on the ground.

"The four formations of 'Elimination' and 'Retreat' are drawn in the elimination center to form a summoning formation."

While Shirou was preparing for the summoning ceremony, summonings were going on in several other places at the same time.

……

In a corner of the remote mountain town of Fuyuki City, there is an open space surrounded by rows of trees.

After confirming that no one was around, Weber Velvet carefully began to prepare for the summoning ceremony.

He took out a live chicken from the backpack he was carrying. Looking at the flapping chicken in his hand, Weber, who was highly nervous, looked around uneasily.

Although it had nothing to do with it, carrying out the summoning ritual secretly still gave Weber the feeling that he was committing a crime.

He took out a knife and cut open the chicken's neck. While the chicken's blood was still hot, Weber quickly drew a pattern of a magic circle on the ground.
