Author's Note:

I came up with Gilgamesh joke this chapter (where he goes out to have fun.) And how he gets addicted to it while Kirei is addicted to his favorite food from Hollow Ataraxia. And Kirei is that guy's master, of course.

And the word "Heaven's Feel" shows up.

Chapter I: Saber from the Previous War

Kiritsugu standing parallel from Angra Mainyu. They were currently holding each other up at the front yard of the school.

Shiro, having made it outside saw Kiritsugu holding a black object, ready to attack.

Dad's… gun?

Shots rang, and they flew towards Avenger.

"….."

Avenger didn't feel a thing. In fact, the bullet burned on contact with his intense Prana aura.

Hmm, so only attacks made using Prana will work against him…

Although Kiritsugu was already preparing from the beginning, he didn't have enough time to solve his lack of firearms workable against Servants.

Shiro didn't realize Kiritsugu was actually going to fight, not having said it directly.

Shiro, although I won't be a Master, I will be by your side.

Shiro, remembering his time at the Emiya mansion, didn't know what he meant.

Realizing that now, he ran towards Kiritsugu, knowing that he was in grave danger.

The space around was slowly draining life's Prana.

It was like Avenger had a natural Bounded Field around him, absorbing soul energy from all life.

Tch, if he expands that… then the people will—

"Dad…!"

Shiro, running towards Avenger, swung his twin swords.

The swords repeatedly clashed, red and white, with Avenger's arms.

Sparks were flying around like a flint stone rubbing itself on steel, shredded in just a second—

Every time a spark flew, a new set of sparks would come in just one-tenth of a second.

And Shiro was beginning to break a sweat.

"Why can't I hit him!?"

Immediately, a huge aura of Prana burst from Avenger, finding him to be a nuisance.

"Guaaah!"

Shiro, suddenly repulsed by a huge influx of power, was blown away.

His back hit the wall, making him cough out blood.

An amount of Prana incalculable, even by a Magus and Servant's standards… This is troublesome.

Kiritsugu, with nowhere to go, shot his bullets one by one—

And they would burn upon contact.

There's no way I can defeat him… No, it will be impossible, even with a nuclear bomb…

One step.

The Prana Aura was gaining momentum.

Shiro eyes him, unable to do anything.

Two steps, Avenger smiles.

Shiro becomes anxious.

Three steps, Avenger stops.

And laughs.

"KeHaAhaHahA! KiRiTsUGu, lOnG TiMe nO SeE!"

"So you know Kirei… He was looking for you all this time…"

"Hahahaha! As a priest who has been looking after me, I'm glad he did! Because he took me in to his church to become the ultimate Servant! Angra Mainyu!"

"Takadana… you…"

Shiro, having had enough, was standing up, blood dripping from the corner of his mouth. He was slowly dragging himself to Avenger.

"The Heaven's Feel… do you know it?"

Kiritsugu, upon hearing those words, his eyes open in disbelief.

"No, it can't—"

"Yes, and it is all due to that Curse of yours, the curse given to you by me, Angra Mainyu, the vessel of the Tainted Grail when I touched you that day~"

"…!"

Stifled breath.

But not now, he can't die, even with this curse.

Because he wanted Shiro to become even greater than him, the greatest Heroic Spirit that ever lived. A true Hero of Justice that can save a world from disaster. Time and time again.

For that, he would do any—

"Now die and go to Hell, one who killed my parents!"

The Aura of Prana was consuming the very space in front of Kiritsugu, and just as he was about to—

"Damn it! I've had enough of this! Somebody, save him…!"

Having already drawn a Summoning Circle while rushing, he summoned his will to it—

"SABER!"

He screamed many times above his normal voice, even to the point of almost cracking his throat.

A Servant, in blue and silver armor, with the body of a princess, yet the majesty of a knight—

She came charging forth, galloping in her steel armor, ready to deliver the judgment of honor—

"Tch!"

Avenger, before his hand could grab Kiritsugu's face—

He was repelled easily away by Saber, making him stagger back a little more than a few feet.

So she pushed him back… Well done, Saber—

Kiritsugu fainted.

Saber eyes him, unable to hide the shock on her face.

"…!"

She stares at him for ten full seconds—

Then realizes that Avenger was looking.

"Hoooh~? Somebody here sure loves to whine~"

"Who are you!? And what are you doing here!? Somebody like you—"

"Heh heh heh, just go listen to that guy over there~ He knows~"

Suddenly, Avenger grabs his heart in pain.

"Tch, looks like I used too much…"

Then he suddenly looks back up at Saber.

"Ah~, but make no mistake~ I'll be back~"

And Avenger starts to disappear—

"Wait!"

Before Saber could tear apart his flesh—

It disappeared, and the evil Prana staining the air had vanished.

Saber, looking back, saw Kiritsugu, who looked frail and weak compared to those years ago.

What happened to you…?

Saber, looking at Kiritsugu, draws attention to her Master.

"Saber… I knew you would… come…"

Shiro staggers towards her, walking step by step. Before he could reach her, he fainted.

Just as he was about to fall, Saber caught him, letting him rest.

"Ah, so you're…"

She looked at him, staring for a long time.

The back of his head… That red auburn hair…

Even though it didn't match his black hair… It still felt like him…

You seem to be him, yet you aren't… Are you two… together?

She smiled when she realized this. But when she looked at Kiritsugu—

"…"

She didn't smile in the least bit.

What happened to him… That made him like this?

What happened before… was in the previous Holy Grail War.

And how it came to be… that Kiritsugu was a trigger for the early awakening of Angra Mainyu.

Avenger… and Kirei.

She picked up both Shiro and Kiritsugu, and fled off to somewhere it would be quiet…

The Church:

Meanwhile, at the church—

An organ was playing, yet though it sounded peaceful and quiet, there was a raw sense about it.

A priest, who was playing the organ, was doing it for someone to hear.

There was a golden armored Servant, listening to the chimes of the instrument while nodding his head.

Yet there was a hint of annoyance about it that made him angry.

"Hmph… mongrel, are you enjoying yourself?"

"Huhuhu, yes, I am. Are you enjoying this?"

An arrogant voice belonging to the golden Servant, and a deep voice to the priest of the Church—

"Hmph, there is no way a king such as I can enjoy something worthlessly peaceful like that, although it is to my liking…"

While talking, they suddenly look to the source of Prana flooding the Church.

"Ah, Avenger, are you back so soon?"

Tch! If only if I had enough Prana…!

The voice fills the whole choir of seats, and the back of the room vibrates.

"Hush hush, Evil One, you will have another chance later on. Right now, sit back and let Gilgamesh do the work while you gather energy."

Tch, resting for another Quarter Seven Days again, as you call it… I really hate this, I just want to kill that bastard right now!

"Ho? You mean Kiritsugu? Hmm, I have a surprise in store for him. Just wait, Avenger."

Tch, and to think you could actually handle the two of us at the same time… You are one hell of a clever bastard... Taking all these children and letting us eat them…

What they were talking about was all the dead, decaying bodies in a hidden room of the church. And they were all abandoned children who came to the Church to seek shelter while waiting for an adopter to come.

When actually, they were being consumed by Gilgamesh the whole time, to keep Gilgamesh alive after the previous Holy Grail War—

The one that set fire to Fuyuki. And would have killed Shiro were it not for Kiritsugu.

The final battle between Kirei and Kiritsugu… It was how they were both cursed by the Tainted Holy Grail.

Even now, Kirei still chuckles about it.

"Huhuhu, Kiritsugu, I will be waiting..."

"Hmph, talking about another mongrel again I see…"

Then the organ started playing higher notes, and Kirei was chuckling the whole time.

Kiritsugu, just you wait… I will show you… the true Heaven's Feel that will destroy everything you hold dear… and we will see if you can stop it. Including that boy...

Kiritsugu, sadistically smiling, was laughing the whole time—

"Huhauhahaha...! Hahahahahahaha—"

Gilgamesh's brow twitched looking at him smile like one of those people.

"Yet another mongrel that has went completely mad over something that pleasures him to no end…"

Gilgamesh, sighing, summons a bottle of wine and pours it into a cup, drinking while thinking.

I will watch the world until its end. I am curious as to how Kirei's adversary shall overcome this challenge.

Gilgamesh, after drinking the whole bottle of wine, summons fashionable clothes.

"Kirei, I will be going out a while to explore the world's fashionable designs… And I shall be out for dinner tonight."

Kirei stops smiling, noticing this sudden change of pace.

"Ho~? Are you interested in experiencing this world… before the end?"

Gilgamesh smiles arrogantly.

"Mongrel, you know me all too well. I will bring back that favorite food of yours… that… 'Mapo Tofu' as you call it."

"Huhuhu, bring it back to me. We shall enjoy a dinner of extravagance… Huhuhaha… Hahahahahaha—"

A golden brow twitches.

"Tch. I am getting fed up with a mongrel's want for such low quality food… I shall enjoy my time out there away from this madman tonight…"

Gilgamesh, with the church doors closing behind him—

"Before the world ends… I shall acquire all there is to know about man…"

And before he knew it, once he saw his first Anime—

He would stay stuck to experiencing Japanese culture past midnight into early morning. Addicted to the cartoons that children take so seriously.

"Hmm, now what should I see first…"

Gilgamesh, seemingly not knowing where to go, takes the route toward the most souls.

And smiles once he sees a billboard with an Anime girl on it.

En-route to the Emiya Mansion:

Somewhere along the way, Saber was flying with both troopers in arm:

One Kiritsugu and one Shiro.

Kiritsugu, unfortunately, was the first to wake up.

"Nnn…"

Kiritsugu, seeing that it was mid-afternoon already, looks up at the blue shadow covering his eyes.

Saber, however much she would have liked to let go of Kiritsugu right now and let him fall to his death, she couldn't.

Because she realized he was Shiro's father.

Kiritsugu… what happened to you?

Instead of holding on to her anger for now, she let it go and kept looking forward.

When they jumped near the Emiya Mansion—

"S… Saber… over there."

He let his hand fall, while he pointed towards a certain mansion.

"Okay…"

Saber, a quiet lion, descended down to the mansion.

A torrent of air fluttered her hair, while Kiritsugu fell asleep.

Tap.

However high she was, she landed down lightly, having descended from over a hundred feet in the sky.

She quickly searched for a room to put both victims in, and found Shiro's room.

Looking at the house, she seemed unfamiliar with it.

So it changed this much…

While looking around, she didn't notice any guns or Claymores like back when he would mercilessly shoot Magi to kill them.

Putting Kiritsugu down really quickly and not tucking him in the futon, she looked at Shiro.

"….."

She softly put him down and tucked him away in a futon.

It was one hell of a day today.

And they wouldn't wake up for a while…
