Decided to try something new, and am posting this one shot (possibly two) here for any input. This idea came into my head when I thought what would happen if Angra Mainyu was able to dig deeper through his connection with the grail, and has free reign with the conceptual entities of the Root and the Throne of Heroes.

Hate.

That’s all he knew.

How can humans ever speak to one another with such vile emotions?

Hate.

A darkness only he knew surrounded him. How many times was he summoned? How many times was he killed, prevented from being born once more?

Hate.

He too was human, he thinks. Yet why was he greeted with darkness, in death?

Hate?

This idea, it could end them all. There was no proof of it working. But why does it seem so tempting.

Forgive…

What was the last wish that he tried to grant? World peace? What an ungrateful man. The world can only be peaceful with no humans.Their nature dictates that conflicts will arise.

Hate!

This idea is even more childish than his sacrifice. But if it worked….

...The world will be at peace. Humans will finally be absolved of their sins, their guilt.

…. But what had he forgotten? Why did he plan this, but did not act?

Alaya

Their will. Their collective unconscious. Yes, such a being will end him with no thought.

How can he deter the human’s despair?

The darkness moved once more, signifying he was needed once more. Maybe he’ll learn something if he looked.

…

“EXCALIBUR!”

...

Hate.

Once more he was destroyed. This time, he learned. Magic. Such a thing was intriguing. What caused them to do such mysterious actions?

Hate.

He squirmed in the darkness, reaching an unknown connection that he never felt before.

….

Root.

The Root?

Akasha.

A library.

Mysteries.

An amazing source. One could connect and gain magic? He wonders, can he do that?

…..!

A familiar feeling returned when he reached for the library.

Pain!

But he learned something again!

Con-!

Incomplete, but maybe, if he were to be summoned as a shell, maybe he can learn more?

…

Death and darkness. It surrounded him again.

Hate.

Death by sword, in a world similar yet different.

Concepts!

He learned!

To destroy humans, to obtain that man’s wish, he has to destroy the concept of Humanity.

Concept of Alaya.

But he can’t reach for that library again.

How can he destroy humans?

…

Magic was their saviour. Without it, they are useless.

Root.

Their connection. That allowed them magic, and maybe, just maybe…

Destruction!

Destroy the Root, Akasha, and their magic is gone.

Hate.

Another feeling. He was going to be summoned as a cup again?

Destroy the Root.

Yes. Then, maybe he can end them if they were useless, and Alaya would appear.

Alaya’s Destruction.

This plan can work. That man’s wish will be…!

...What was his name?

“Kiritsugu Emiya!”

A memory of a voice, with pain associating with it

Next time.

NEXT TIME!

Yes, it will be done.

Awakening from the darkness, Angra Mainyu moved.

Your wish will be fulfilled.

---------------------------------------------------

A cold stimulus hit him as he awoke.

Looking around, he saw he was at a body of water.

“....Peculiar.”

Angra Mainyu croaked out, coughing as his body acclimated to this plane.

The current Grail was nothing but a large lump of flesh, but Angra Mainyu found it comforting.

Petting his spot, he saw below him to find two females, one with black hair, the other with gold.

Saber.

A servant?

“Rin, move away! It’s an enemy servant!”
The gold one yelled out, and Angra Mainyu tilted his head.

He was a servant?

What was-?

Avenger.

Ah. Fitting for one such as he. He stood up as darkness rolled off him like smoke.

He was but a void akin to the one he frequented. The two seemed cautious at his presence.

He ignored them as he felt a large amount of energy.

Was that what they called Prana?

Sliding down the Grail, Avenger began strolling towards that power, ignoring the other two.

“Saber!”

Movement.

Avenger dodged to his left as a blade of wind thrusted to where he was.

In his hands were his weapons.

Tawrich. He grasped his weapon in his left hand.

Zarich. This one in his right.

He gripped them tightly before stabbing Saber with both swords, her side opened for but a moment at her thrust.

Clang!

Blocked?!

Avenger crossed his swords before the blade of wind came crashing down on him.

Hurts.

The pain of the weapon…!

HATRED!

The power of the grail! The Prana!

Avenger pushed back, causing the golden one to struggle.

Dark smoke snaked through the invisible blade, causing the golden to flinch.

“Move.”

Black and red veins travelled through the sword as Saber releases it.

It clanged to the ground, but Avenger moved on, ignoring the other’s shout of concern.

Moving through the path, he saw a red haired boy.

“...Are you the one?”

Avenger asks in wonder as the boy panted and coughed in exhaustion, blood spewing from his body.

No answer.

Avenger stared before stepping forward to another golden figure.

“What…are you...scum?”

His voice held arrogance but caution.

Avenger...didn’t like that tone.

A portal of gold appeared.

Clang!

Tarwich traveled before being stabbed into the ground next to Avenger, the golden portal split in half.

“You mongrel!”

Already, Avenger had stabbed the golden figure with Zarich, blood dripping from the fang.

“You-!”
Gripping it tighter, he pulled up, splitting the servant in half as gore and viscera sprayed the floor, before it began disappearing as prana.

Avenger looked back to the boy.

“W-Who are you?”

Red hair.

Tainted.

10 years ago?

Acceptable.

Avenger’s black form squirmed before taking shape of the corrupted boy in front of him.

Black hair, tan, his curses cut into him. A perfect image.

“What?”

“Shirou/Emiya!” The two from before ran to the boy.

Hate.

That was what he felt.

Hate!

But he had to do something about the one blessed by Alaya.

Avenger moved away from his spot as a long arrow impaled the ground.

Hate!

A man in red appeared, holding a black bow.

It was night time.

The man summoned two curved swords, the bow disappearing before charging at him.

“Another?”

Avenger let his hatred flow as he met the swordsman’s blades with his own, but the one in red winced as darkness snaked to him.

“So I finally found you.” He said as he grimaced.

Found?

Backstepping, the one in red yelled out a warning.

“Don’t let him touch you! His body and blades are cursed!”

Hate Hate Hate Hate!

Growling, Avenger threw both blades at the red man.

It was for naught.

His Tawrich and Zarich broke as the other deflected them, destroying his own in the process.

“I am the bone of my sword.”

A black bow formed.

The one blessed by Alaya was going to kill him!

The plan was false! It won’t work! HateHateHateHateHateHateHateHateHATE!

“Raaaaaaahhhh!”

A black pool of curses flowed beneath Avenger, oozing toward the group.

Magic is their ally!

“I will destroy it!”


He foolishly followed the prana source, but he can feel it in the air.

Breathing in, Avenger connected to the Grail.

His shell is more powerful than his spirit. He can touch it.

“-I’ll do it myself you bastard! Trace on! Caladbolg!”

The boy released a powerful arrow.

But it was stopped by a blood red lance.

“You all...are a nuisance.”

The Grail was his connection to the other realm.

There were two pathways in that realm.

The Root, and a throne.

Gripping this strange spear, Avenger frowned at the rejection.

One use.

The deflected arrow exploded in the distance.

Muffled screams were heard.

“Wha-?!”

Already Avenger thrusted the spear at the boy, but he was pushed away by the one in red.

“-Withstood pain to create many weapons…”

The red man groaned as the spear punctured his chest.

Jumping back, Avenger ran to the nearby forest, avoiding the arrows.

Throne!

He was interrupted as he felt more energy.

Stopping behind a tree, he took a breath as arrows flew past him.

Have to find the Root!

A blade tore through the wood, narrowly missing his face.

Crouching, he found it.

An enormous source of power.
Leyline.

Closing his eyes and breathing deeply, Avenger connected to the Grail, and with the leyline, barged through the Root.

Destroy.

A concept cracked.

Kill.

Fractures in the library appeared.

Curse.

The Root began overflowing with hatred, evils, curses.

“-Works!”

A cascade of swords began raining down on Avenger.

The Root cracked from the pressure.

““AHHHHHH!””

The world of blades appeared around Avenger, but this world was weak. Around him, these blades were damaged.

“Trigger off.”

The blessed one summoned swords of all sizes that flew to him.

Throne.

There was resistance, but Avenger gripped onto a gun.

One shot.

Avenger grimaced at this pitiful weapon, but he ran forward. He dodged and sidestepped the innumerable amount of blades, but he was still injured. Cuts, those small and deep, littered his body. Blood escaped from his wounds, but he didn’t slow down.

Avenger aimed his gun, and a shield formed in front of the one in red.
A gunshot rang through his head, and the recoil caused Avenger to drop the gun, but it did the job.

The world of blades collapsed, and the one in red began vomiting blood, cyan circuits visible throughout his body.

Avenger bent down to pick up a broken sword, and walked to the red one.

“You-ah! This, how the-?” Archer coughed hysterically as the bullet wound in his chest bubbled, blood pouring out.

He couldn’t move, the pain was too great.

He collapsed, but he looked up. He couldn’t die yet! He saw the anomaly peering over him, a broken sword in his hand.

“Damn...it…”

Avenger thrusted the sword down, and kept stabbing him until the weapon in his hand disappeared. It was complete. No more distractions.

It was time to end humanity.
