My Fates Codex in Type-Moon

My Fates Codex in Type-Moon, by Sunset Tavern

Synopsis:

"So why does Emiya keep barging in everywhere? Could you stop summoning me already?"

The odd one out among the Emiya line, the last Knight of the Round Table, Chaldea's conscience, the Third Magician, King of the Lostbelts, the man Alaya could never have, a sister-loving demon god: Sakutsuki.

When Heroic Emiya called forth a soul from another world in the dungeons of Einzbern Castle, the young man holding the Fates Codex embarked upon a journey of his own.

The earliest Fate Zero; a planet with its Greater Source depleted; a Holy Grail War joined by fourteen Heroic Spirits; Grand Order, rising up to save humanity...

May it continue like this, traveler from another land—

Until the moment fate came full circle.

"I really just want to stay home like Merlin! At this rate, I'll get split into N equal parts sooner or later!"

"Like you aren't already, Onii-chan!"

Let us begin with a certain man.

Weaving vessel... successful

A man who had once possessed fleeting happiness, only to have it stripped away by fate.

Implanting Fates Codex... successful

His little sister had been taken by his best friend and made into a sacrifice for all humanity.

The underclassman who deeply loved him had her heart taken by her older brother because of him.

In his despair, he prayed to the Hall of Heroes, but the only one who answered was himself.

Loading Heroic Spirit (Emiya) template... successful

The people important to him were already gone, and the glory he had inherited had been cast aside. What his true self revealed beneath it all was an incurable emptiness.

Class proof: Berserker, Assassin, Archer registered

Having abandoned his dream and betrayed the guardian of humanity, Emiya became the most insane, most reckless evil and ended the Holy Grail War in a single night.

He had ultimately failed to become a hero of justice, but... he had won.

Counter Force (Gaia) interference detected... severed

Counter Force (Alayah) interference detected... title of Guardian revoked, all abilities reduced

He successfully made his wish and brought salvation to his sister, yet he was ultimately no match for the sword that split the world apart, falling amid the boundless snowstorm.

In the silent dungeon, the dying man reached his end.

██ returned, converting... fusion successful

Just as King Solomon saw the future of Humanity Incineration the moment he became an ordinary man, and King Gilgamesh observed the culprit behind humanity's destruction while half-awake in a dream—before the man's consciousness completely sank into silence, he too saw fleeting glimpses of the future.

It was a brief joy that had once existed.

It was an inescapable spiral of fate.

The man realized that his sister would eventually return here, to this world of despair.

Inherent Skill: "Never-Ending Grief" forcibly acquired

Ah... still futile.

At death's door, the man sighed like this.

Within his ragged, puppet-like body, an emotion called "regret" struggled desperately.

If only he had realized his limitations sooner. If only he had understood his true feelings sooner...

If there were someone more resolute than me, stronger than me, to walk this path in my place...

Then...

This fate...

Perhaps it could be saved...

██ activated, searching... suitable individual found

Individual name: "Shirou Emiya" dormant

New individual implanted, vessel activating... activation successful

Transmitting memory data... transmission complete

Ability parameter "Luck" increased to B

When the brand-new consciousness awakened and opened those pale golden eyes, what he heard was the man's final wish.

"Don't ever forget... You promised her you'd take her to the beach..."

This was the twisted origin.

Readers who can't follow this may proceed to the next chapter. This chapter won't affect your reading afterward!

Also, if you truly can't understand any of this, I suggest catching up on the FATE anime series or its setting before reading further. It is fanfiction, after all. Hehe.

Inside a certain department store.

Endless corridors, chaotic intersections, and doors that appeared hazy beneath the setting sun.

Blond hair, golden armor... A golden figure walked through the place as though all its radiance had gathered around her.

Amid the crisp clatter of armor scraping together, the unusually dressed woman, her body marked with crimson patterns, never slowed as she passed through the fire door of the emergency exit—

What appeared before her was not a staircase leading to an escape route, but a cramped changing room... and deadly blades shooting out in an instant!

Facing the sudden assault, the woman named Angelica snorted coldly. Golden ripples spread around her, and even sharper blades flew from them, smashing the weapons before dissolving into spiritrons.

She violently threw open the changing room curtain and stepped inside. In the television section, televisions of various models sat silently, like spectators mocking her disheveled state.

"Enough!"

Her last shred of patience had been worn away. With an angry shout, the woman's rage transformed into a sweeping storm of steel. Countless weapons launched from golden ripples, wantonly destroying everything around her.

Fragments of LCD screens scattered through the air, reflecting her face, dark as still water.

Angelica knew that this building had already become another world. Under the effects of magecraft, space itself had become as incomprehensible as a tangled ball of thread. Even though she possessed the same magecraft, she could not untie a dead knot—unless she was willing to waste an entire night carefully straightening it out and restoring it to normal.

But if she did that, that man's objective would be fulfilled.

So she had to escape this quagmire faster and more decisively—and there was only one way to do it!

The woman who commanded ancient mysteries raised her right hand. Countless golden ripples opened behind her:

"Gate of Babylon, fully unleashed!"

At her command, the gates connecting to the treasury of the "Golden Capital" opened completely. Countless Noble Phantasms, countless miracles shot forth from golden ripples, granting this space the most violent, most exhilarating death imaginable!

The distorted space was torn apart and returned to order.

The hidden magecraft was dismantled, its mystery erased.

The Displacement Magic entwining this space vanished together with the department store.

Beneath the blood-red sunset, only the golden figure stood amid the ruins of the building, her hollow, emotionless blue eyes fixed upon the white-haired figure facing her.

"I caught you... Shirou Emiya. Do not even think of resisting. Return the Class Cards made by Lord Darius, go back to Einzbern Castle, and continue accepting imprisonment—then a lowly counterfeit like you may live a little longer."

Under her murderous gaze, the young man's lips curled up in a smile completely unlike Shirou's original one. He raised two fingers.

"First, I am not the Shirou Emiya you imagine. You may call me Sakutsuki. Second, Angelica Einzbern, a doll that gained the power of the ancient Hero King by using Displacement Cards..."

Sharp weapons pierced the young man's body, yet he continued smiling, his words full of mockery.

"And you think you're worthy of catching me?"

More weapons shot toward him, piercing his face and tearing apart his mocking smile. Yet when the illusion faded, what appeared before Angelica Einzbern was merely a lifeless puppet.

"Displacement Magic... Tch, Shirou Emiya—no, Sakutsuki." Angelica crushed the puppet beneath her foot. Though she had lost most of her emotions, this rat that kept darting around had still enraged her beyond measure.

"How did this bastard obtain the Einzbern magecraft?!"

Several kilometers away from the department store, in a church, the white-haired, golden-eyed young man opened his eyes and scratched his head in annoyance.

"Mm, even the last puppet I swiped from Einzbern Castle has been used up... Gil-Girl really is troublesome."

Whenever he thought of that golden figure, his head began to ache.

On the surface, he had mocked her and escaped unscathed, but no one knew better than him how difficult that woman was to deal with.

With a thought, dark blue text appeared in his vision, forming a small panel.

Fates Codex has unlocked new information

001: Angelica Einzbern

Character Information: A doll (DOLL) of the Einsworth Family, working part-time as a maid. She can skillfully use the Einsworth Family's Displacement Magic, exchanging space to create portals or exchanging a person's soul with virtual consciousness to create puppets possessing only virtual consciousness.

Hidden Information: Unavailable

Recording Conditions (2/3)

1. Escape Einzbern Castle (Completed)

2. Successfully evade her pursuit for seven days (Incomplete)

3*. Hidden condition

At this point, the young man's identity was already obvious—

That was right. He was a transmigrator who had come from another world, been reborn through Shirou Emiya's body, and obtained the cheat known as the "Fates Codex"!

After awakening, Sakutsuki quickly grasped the situation by analyzing the remaining memories in this body.

He had arrived in the vast world that had been fictional in his previous life, created under the leadership of a certain mushroom.

A dazzling world of endless wonders, endless branches, and World Lines.

Although, upon learning this truth, he had nearly struck a JOJO pose as a Type-Moon fan, reality forced him to give up because his hands were bound. The memories from the previous owner, from Shirou Emiya, were so deeply etched into him that he understood one fact:

This was the World Line of "Fate/kaleid liner," in other words, the world of Magical Girl Illya.

And the present point in time was just after the movie "Magical Girl Illya: Oath Under Snow" had ended. Heroic Emiya had failed in his direct clash against Enuma Elish, taken EA head-on, been defeated and captured, then imprisoned beneath Einzbern Castle.

But in this world, Heroic Emiya had not endured until Miyu returned. After summoning a soul from another world, he died.

—Even though the previous owner's will had already dissipated, Sakutsuki, who had inherited this power and this will, would continue opposing Einzbern.

Thus, he concealed his presence.

Thus, he broke free of his shackles.

Thus, while Angelica was away, he slaughtered his way out of the dungeon and into the heart of the enemy's territory.

Although he allowed Darius, head of the Einsworth Family, to escape amid the chaos, Shirou Emiya—no, Sakutsuki—still seized the five completed Class Cards he had created, along with a blank card that granted power but had no Class set, and departed in triumph.

His wandering thoughts returned. The white-haired young man let out a faint sigh.

"Come to think of it... this is already the seventh day, isn't it?"

The dark blue panel in his vision faded. Five cards bearing the marks of different Classes blossomed and folded together in his palm like flowers. Then Sakutsuki rose and stretched beneath the moonlight flowing like water.

"Why hasn't that fake priest Kirei Kotomine returned yet...? Don't tell me he's hiding from me?" The young man sighed helplessly, then took a step and appeared directly outside the church. "Forget it. I'll spare his life. I'd better leave before Gil-Girl catches up."

A diamond-shaped pattern seemed to emerge beneath his feet. As the magecraft activated, space seemed to be exchanged, losing its original distance, and swiftly carried Sakutsuki away from the church.

Displacement Magic—

As one of the introductory magecrafts, it was a low-level foundational spell based on degraded exchange, seldom used by anyone. But in the hands of the Einsworth Family, who specialized in it, Displacement Magic surpassed common sense in scale, precision, and range of application, even reaching intangible concepts such as space and the mind.

That was right. It was the only magecraft possessed by the Einsworth Family, whom Sakutsuki opposed. It was extremely powerful in actual combat and impossible to guard against. Angelica had used this very magecraft to evade Heroic Emiya's fatal strike.
