Death and protection, madness and mystery, heroic spirits and bonds, fakes and real objects, will eventually intertwine.

Every day you don't dance is a day you betray life.

Come, let us fight until dawn!

"This body is destined to be formed from the Infinite Sword!"

Chapter One: Winter Returns

dong dong dong...

There was a knock on the bedroom door.

"Shirou, the hot water is ready. Go take a bath."

Mrs. Orihara's soft, gentle voice drifted in.

"coming!"

Shirou stood up and walked out of the room.

After the door opened, a beautiful young woman with smooth, bright red hair tied in a braid and hanging down to her chest stood beside her, looking at Shirou with a smile.

"I already said I don't need anyone to accompany me when I take a shower..."

Shirou said, somewhat speechless.

Mrs. Orihara has always liked to do this since she could walk, and now that she's in elementary school, it's really bothering Shirou.

"Oh my, that's true. Shirou's already seven years old in the blink of an eye!"

After saying this in a somewhat playful tone, Mrs. Orihara left with a smile.

Shirou breathed a sigh of relief, then entered the shower room. After closing the door, his expression became slightly serious.

"what can we do about it……"

Shirou, who was born into this world seven years ago, is currently in elementary school.

Over these seven years, Shirou came to understand the kind of world he lived in.

————Type-Moon!

He is currently in the Type-Moon world, specifically in Fuyuki City during the Fourth Holy Grail War!

That was a place where seven magicians summoned heroic spirits to fight each other, all for the sake of obtaining a broken cup that was stained with menstrual blood and whose granted wishes were all twisted!

In fact, upon understanding all of this, Shirou immediately suggested to his parents that they move away from Fuyuki City.

To Shirou, the city seemed to be a collection of jokes, impermanence, and chance.

With the Fourth Holy Grail War drawing ever closer, going to Chiba, Saitama, Ikebukuro... anywhere is safer than staying in Fuyuki City!

Unfortunately, Shirou is only a seven-year-old child, and many things are beyond his control.

Even gentle parents like the Orihara couple wouldn't abandon their decent jobs in Fuyuki and immediately move to an unfamiliar city just because their seven-year-old child mentioned wanting to move, without any prior incident.

Recently, Shirou's memories have started to show some abnormalities.

For some reason, Shirou sometimes has memories that shouldn't exist, fragments of memories of people who died in various ways, that sometimes flash through his mind.

In each memory, he was trying to do something, but he failed every time.

But these memories also brought some benefits, allowing him to master certain skills, such as combat techniques, firearms handling, and counter-surveillance...

Pulling himself out of his thoughts, Shirou looked at his reflection in the mirror embedded in the washstand.

With reddish-brown hair, brown pupils, a fair and youthful face, and a stubborn look in his eyes, his eyebrows are shaped like lightning bolts.

Because the genes of the Orihara couple were perfectly inherited, Shirou was very popular with girls at school, and his family was also well-off.

If it weren't for the Holy Grail War, he would probably have lived an easy and comfortable life.

After a relaxing shower, I returned to my room only to find that it was already ten o'clock.

Shirou returned to his room and looked around his bedroom.

What comes into view is a room the size of six tatami mats, with not much furniture, but all of it is exquisite.

Thanks to Mrs. Orihara's meticulous care, the furniture was spotless, the few decorations on the table were unique, and there was even a small potted plant by the windowsill.

Looking at this cozy room, Shirou's eyes softened; it held all his memories from the past seven years.

Shirou glanced out the window.

The sky turned the color of the dark night sea.

As the night grew later, the air became increasingly cold, as if cut by a knife.

On such a night, the Fuyuki Bridge, which divides Fuyuki City from its old capital to its new capital, merges into darkness along with the Miwa River below.

Looking at the scenery of the new capital, Shirou's gaze became increasingly distant.

"I don't know if the Holy Grail War has started... I only know it's in 1994, but I don't know the exact date..."

As he pondered, he grew increasingly sleepy. Continuing to engage in meaningless thinking would only lead to mental exhaustion, so Shirou lay down on the bed and fell asleep.

……

early morning.

The warm winter sunlight shone through the half-drawn curtains, its orange beams floating and swirling.

"Shirou~ Breakfast is ready, time to get up~"

Urged on by Mrs. Orihara, Shirou wakes up from a series of strange dreams, including "a magical girl running into the house," "Gudako suddenly running to the door and dragging him to a singularity," "Greek gods lining up to fight," and "a phantom red dragon opening its giant mouth at him."

Shirou opened his eyes and saw a gray ceiling, and he was slightly lost in thought.

Suddenly, he noticed a small white dot that had appeared in the lower right corner of his field of vision.

"what?"

As Shirou focused his attention slightly, the white dot rippled, and then a semi-transparent panel suddenly unfolded in the center of his vision.

"This is……"

Shirou was slightly lost in thought as he stared at the semi-transparent panel that had suddenly appeared before him.

[Name: Orihara Shirou]

【Sex: Male】

[Age: 7 years old]

【Height: 134cm】

[Race: Human]

[Bloodline: None]

[Special ability: none]

【肉体强度：6（10）神经反射：7（10）生命力：6（10）精神力：27（10）】

At the very bottom, there is a note indicating that the values ​​in parentheses are the standard human values.

"It's a bit like an attribute panel in a game, but I seem to be a bit weak."

But thinking about it carefully, reaching this value at the age of seven doesn't seem that low.

Perhaps it's because Shirou has always been doing proper training that he's like this.

"Your mental strength is a bit too high... How did you manage to improve it to this level?"

As Shirou was carefully analyzing the situation, there was another knock on the door.

"Shirou, aren't you getting up yet? The food's getting cold, and you're going to be late soon..."

The one calling for Shirou is Mrs. Orihara, who is puzzled as to why her child is still in bed and about to be late.

This child used to get up on time every day.

Even though she had some doubts, Mrs. Orihara's second reminder was still delivered in the same gentle tone, showing her to be a mother as gentle as water.

"I understand, I'll be right there!"

Shirou quickly got out of bed, dressed, and left the room for the bathroom.

As Shirou started brushing his teeth, Mrs. Orihara said to him from the living room, "I've put your lunchbox on the table. Remember to get it yourself later."

"okay."

Shirou readily agreed, then filled a cup with water to wash his mouth. After rinsing his mouth, he hurriedly stuffed the bento into his schoolbag and headed towards the entrance.

"I am leaving!"

As Shirou reached out to close the door, Mrs. Orihara's gentle voice came from inside the house.

"Safe travels!"

Hearing that voice, Shirou smiled and replied.

"it is good!"

Then, Shirou started walking towards the school.

……

It is winter now.

Fuyuki City, a seaside town, gets its name from its supposedly extremely long winters, but in reality, its climate is relatively warm and it is rarely hit by severe cold.

However, the recent weather has been an exception.
