My Fates Codex of Type-Moon

Type-Moon's My Fate Codex - Author: Sunset Tavern

Introduction:

"Seriously, why is Emiya popping up everywhere? Can you stop summoning me already?"

The anomaly of the Emiya series, the last Knight of the Round Table, Chaldea's conscience, the third True Magic user, King of Lostbelts, the man Alaya can never obtain, the demon god obsessed with his sister: Sakutsuki.

When the great hero Emiya, in the dungeon of Einzbern Castle, summoned a soul from another world, the youth holding the Fate Codex embarked on his journey.

The initial Fate/Zero; a planet with a depleted Great Source; a Holy Grail War joined by fourteen Heroic Spirits; the Grand Order initiated to save human history…

Continue on like this, traveler from another land—

Until the moment the cycle of fate closes.

"I really just want to stay home like Merlin! If this keeps up, I'll be split into N pieces sooner or later!"

"Aren't you already, Onii-chan!"

Let's start with a certain man.

[Weaving vessel… Weaving successful]

The man who once possessed brief happiness, only to have it ultimately stripped away by Fate.

[Fate Codex implanting… Implant successful]

His sister was taken by his best friend and became a sacrifice for all humanity.

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

In despair, he cried out to the Hall of Heroes, and only he himself responded.

[Heroic Spirit (Emiya) template loading… Loading successful]

The person important to him is no longer here, the glory inherited has been cast aside, and the true self exposed because of it—is an incurable emptiness.

[Proof of Class: Berserker, Assassin, Archer, registered]

Abandoning his dreams, turning his back on humanity's protector (Emiya), he transformed into the most insane, most reckless evil, ending the Holy Grail War in a single night.

He ultimately did not become a hero of justice, but… he won.

[Detected interference from Gaia… Intercepted]

[Detected interference from Alaya… Protector title revoked, all abilities decreased]

He succeeded in making his wish, saving his sister, but he himself could not withstand the sword that tore through the world, falling amidst the wind and snow.

In a quiet dungeon, the dying man met his Fate.

[██ returned, converting… Fusion successful]

Just as King Solomon, the moment he became a normal person, saw the future of human incineration; just as King Gilgamesh, in a half-dream, observed the mastermind behind humanity's destruction—the man, before his consciousness completely faded, also saw fleeting glimpses of the future.

It was a brief joy he once had.

It was an inescapable spiral of fate.

The man realized that his sister would ultimately return here, to this world of despair (Fate).

[Inherent Skill: 'Endless Grief', forcibly acquired]

Ah… still futile.

In his dying moments, the man sighed thus.

Within his body, tattered like a doll, the emotion called "regret" struggled.

If only he had realized his limitations sooner, if only he had understood his true feelings earlier…

If only someone firmer than me, stronger than me, had walked this path in my stead…

Then…

This kind of Fate…

Perhaps it could have been saved…

[██ activated, searching… Suitable individual found]

[Individual name: "Shirou Emiya" has been silenced]

[New individual implanted, vessel activating… Activation successful]

[Memory data transfer… Transfer complete]

[Ability parameter "Luck" increased to B]

When a new consciousness awoke, opening those faint golden eyes, the first thing he heard was the man's final wish.

"Don't forget, you promised her you'd take her to the beach…"

This was the twisted origin.

Readers who don't understand can move to the next chapter; this chapter does not affect the subsequent reading!

Also, for those who truly don't understand, it's recommended to catch up on the FATE series anime or lore before reading, as this is a fanfiction after all (hehe).

Inside a department store

An endless corridor, a maze of intersections, and doors that seemed hazy in the setting sun.

With blonde hair, golden armor, and a golden figure, he walked through, as if gathering all the light of the place.

Amidst the crisp sound of armor rubbing, a woman with eccentric attire and blood-colored patterns on her body walked without stopping, crossing the fire door of an emergency exit—

What greeted her eyes was not the stairs leading to an escape route, but a small changing room... and a deadly blade that shot out in an instant!

Facing the sudden attack, the woman named "Angelica" let out a cold snort. Golden ripples spread around her, and sharper blades flew out from the ripples, shattering the attacking weapon before dissipating into spirit particles.

She roughly pulled open the changing room curtain and stepped out. In the television store, televisions of various models stood silently, like spectators, sneering at her disheveled state.

"That's enough!"

With her last shred of patience gone, her rage erupted into a sweeping storm of steel. Countless weapons shot out from the golden ripples, wantonly destroying everything around them.

Shards of LCD screens flew, reflecting her gloomy, water-like face.

Angelica knew that this building had transformed into another world. Under the influence of magic, space had become as incomprehensible as a tangled skein of yarn. Even if she possessed the same magic, she couldn't untangle a stubborn knot—unless she was willing to waste an entire night, painstakingly unraveling it and restoring it to its original state.

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

Therefore, she needed to extricate herself from this quagmire faster and more decisively—there was only one way to do it!

The woman, who wielded ancient mysteries, raised her right hand. Countless golden ripples opened, revealing themselves behind her:

"Gate of Babylon, full release!"

At her command, the gates connecting to the treasury of the "Golden City" were fully opened. Countless Noble Phantasms, countless miracles, shot out from the golden ripples, bestowing the most violent and satisfying death upon this space!

The chaotic space was torn apart and returned to order.

The hidden magic was dissolved and its mystery eliminated.

The spatial displacement magic that had entangled this space turned into nothingness along with the department store.

Under the blood-red setting sun, only a golden figure stood amidst the ruins of the building, her hollow, emotionless blue eyes fixed on the white-haired figure opposite her.

"I've got you... Shirou Emiya. Don't even think about resisting. Hand over the Class Card made by Lord Darius and return to the Einzbern Castle to continue your imprisonment—only then can you, you lowly imposter, live a little longer."

Under her murderous gaze, the youth's lips curved slightly, revealing a smile completely different from his usual one. He held up two fingers:

"First, I am not the Shirou Emiya you imagine. You can call me 'Sakutsuki.' Second, Angelica Einzbern, you are merely a doll who has obtained the power of an ancient Heroic King through a displacement card..."

Sharp weapons pierced the youth's body, but he continued to smile, his laughter filled with mockery:

"You think you're worthy of capturing me?"

More weapons shot out, piercing the youth's face and tearing apart his mocking smile. But when the illusion dissipated, what appeared before Angelica Einzbern was a lifeless dummy.

"Displacement magic... Tsk, Shirou Emiya, no, Sakutsuki." Angelica stomped on the dummy, shattering it. Though she had lost most of her emotions, she was still infuriated by this scurrying rat.

"How did this guy obtain the Einzbern's magic!"

Several kilometers away from the department store, in a church, the white-haired, golden-eyed youth opened his eyes and scratched his head with some distress:

"Hmm, I've used up the last dummy I swiped from the Einzbern Castle... She's really troublesome, that 'Shiny Mommy'."

The moment he recalled that golden figure, he couldn't help but get a headache.

Although he had mocked her and retreated safely on the surface, no one knew better than him how troublesome that woman was.

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

[Fates Codex has unlocked new data]

Seeing this, the youth's identity was self-evident—

That's right, he was a transmigator who had been reborn in Shirou Emiya's body and possessed a cheat called the "Fates Codex"!

After awakening, by analyzing the residual memories of this body, the youth who called himself "Sakutsuki" quickly confirmed his situation:

He had arrived in a vast world, fictionalized in his previous life and created by a certain "fungus" leader.

A brilliant world with infinite wonders, infinite branches, and worldlines.

Although he had almost struck a JOJO pose the moment he learned this truth, he had to abandon the idea due to his hands being bound. The memories from the original body, from Shirou Emiya, were so deeply etched that they made him realize one fact:

This was the worldline of "Fate/kaleid liner," the world of the magical girl Illya.

And the current point in time was just after the movie "Magical Girl ☆ Illya: Oath Under the Snow" had ended. The great hero Emiya, after a fierce battle against Enuma Elish, had been defeated, captured, and imprisoned in the depths of the Einzbern Castle.

However, in this world, the great hero Emiya had not held out until Miyu returned. Instead, he had died after summoning a soul from another world.

——Even though the will of his predecessor had already dissipated, "Sakutsuki," who inherited that power and will, would continue to be an enemy of the Einzberns.

He then concealed his presence.

He then broke free from his shackles.

He then took advantage of Angelica's absence to break out of the dungeon and storm the inner sanctum.

Although he allowed the Einzbern patriarch, Darius, to escape in the chaos, Shirou Emiya, no, Sakutsuki, managed to seize the five completed Class Cards, as well as a blank card that had been imbued with power but had no Class set. He then departed triumphantly.

His scattered consciousness returned, and the white-haired youth let out a soft sigh:

"Speaking of which... it's already been seven days, hasn't it?"

The faint blue panel in his vision faded. The five cards, each imprinted with a different Class, bloomed and closed like flowers in the youth's palm. Sakutsuki then stood up and stretched languidly in the flowing moonlight.

"Why hasn't that fake priest Kirei Kotomine returned yet... I wonder if he's avoiding me?" the youth sighed helplessly. He took a step and instantly appeared outside the church. "Oh well, I'll spare him for now. I should leave quickly before the 'shining mother' arrives."

Diamond-shaped patterns seemed to appear beneath his feet. As the magic activated, space itself appeared to be swapped, distorting the original distance and carrying Sakutsuki away rapidly, disappearing from the vicinity of the church.

Displacement Magic—

As one of the introductory magecrafts, its principle was a lower-grade foundational magic of degraded exchange. Few people used it, but in the hands of the Einzbern family, who specialized in this path, the scale, precision, and application range of Displacement Magic transcended common sense, even touching upon ethereal concepts like space and the mind.

Indeed, this was the only magecraft mastered by the Einzberns, Sakutsuki's enemies. It was extremely powerful in actual combat and impossible to guard against. It was precisely with this magecraft that Angelica had managed to evade Emiya's fatal blow back then.
