Prologue

"Kirei! We have won!"

Is that Tohsaka Tokiomi? What the fuck is going on? Where the fuck I am?

This looks like a basement of some sort, and the last thing I remember…

Was playing Fate Grand Order exchanging Mission awards in Saber Wars 2.

Then going to sleep…

Shit…then it's blank...

My gaze went slightly down, I realised that I was wearing golden armour of some sort.

And the emotions… the sheer emotions I was feeling was distaste.

Distaste towards the man who declared that he won...he won what? He thinks that he summoned me that he won…

Wait… a second! Summoned... me? Tohsaka Basement? Tokiomi Tohsaka saying that he won…

Right… my memories…

That moment I realised what was going on… time to act... accordingly.

"Servant… Archer has answered your summons magus. You have summoned King of Heroes, I will assist you in your war for the cup which rightfully belongs to me, since you summoned me you will be allowed to use it once."

So, this is my voice now. It's just like I remember from watching the Fate series, and words...they flow so easily.

Still, I had to control my tongue, I nearly called him mongrel at least three times.

"It is an honour to meet you in person King of Heroes Gilgamesh." Tohsaka Tokiomi slightly bowed towards me, it only made me more distasteful towards him.

Since I know the truth about the cup and its true purpose… that distaste only magnified several times.

Such blatant fake acting is… annoying...

"My name is Tohsaka Tokiomi, the head of the Tohsaka family." The man in a red suit introduced himself to me.

"Very well, then the contract is sealed, don't disappoint me, I hate...boredom…" I said that with a slightly annoyed tone.

This is going to… annoying to reel in the goldies tendencies.

"Of course. I promise this war to be a grand spectacle befitting of your standing, your Excellency." Tokiomi quickly said that.

That moment my memories went back to what I know of Fate Zero, and yes I know… the plot like the back of hand.

That moment I felt like smiling, my...Gilgamesh side or more like the Hedonist side… feels quite satisfied for now from knowing what is coming up in this war.

"That will be for me to decide Tokiomi." As I said that, I turned into golden particles and disappeared, something Gilgamesh added himself... the way he disappears, he is a King so it has to be fancy as possible.

~~~

The Head of the Tohsaka family sighed in relief after seeing the King of Heroes accept the contract, as he was expected from the legends he will be a handful to control.

"So, that is the King of Heroes… a colourful person." Risei Kotomine said.

"His parameters speaking for himself, his Noble Phantasm rating is at EX…" Tokiomi said as he remember the parameters he saw.

The Master of Archer looked at his command seals slightly grimacing he doesn't know if three will be enough for him to control the oldest hero.

~~~

My first thing of business is finding a room in Tokiomi empty manse.

Once I found one, I manifested once more, this time I was dressed like how Gilgamesh has dressed in Fate Zero.

Funny enough these clothes came to mind the very moment I wanted to get out of stuffy armour.

Using Gate of Babylon was nearly something I can do instinctually, it's an extremely fascinating piece of Noble Phantasm from Age of Gods.

Not only that, but I can 'see' what is in the vault.

Once I located a couch I dropped into one, a frustrating groan escaped from my lips.

'All of this… how on earth this happened!? How was I shoved into the body of the blonde!?' I frowned, not that I can panic, the guy's sheer amount of ego dwarfs any sort of panic…

Something akin… to 'so what? You are a King now, you been shoved into this body just get stronger and use EA to turn that individual into dust.'

'This is going to be annoying…annoying to reel in that ego and Hedonism tendencies, especially if they will come in the way of my goal to get a proper body!'

Changing my position back into sitting one I checked myself once again.

Gilgamesh is a perfect male specimen, from height to body constitution.

"The problem is… I want to drink wine and see people suffer… damn…"

Hearing myself like this is going to take time…

A sigh escaped from my lips before a pen and a piece of paper dropped from a golden portal.

"First… learn magic, second reincarnation there is no way in hell a… King like me will serve someone." My eyebrow twitched saying all that, guess calling myself a King is natural like breathing air…

Funny how there was no crowning ceremony, there was simply him...me the one and only King selected by Gods.

In the literal sense.

It is hard not to get carried away by such a thing.

"Third once I get a body I will continue with my magic training and possibly going to explore the whole multiverse since I know it does exist now that… I possess Gilgamesh body…"

Feeling how my…. The hedonist side agreed with this plan even got excited of idea getting more stuff… more treasures, more wine...

Once the bare bones of a plan came to be I can think of winning this fake grail war, since the cup is not real by any stretch.

I looked at my writing which is quite good for a body that never wrote in English before …

"Not bad… it would seem there is some natural talent for everything… I do wonder…"

For a second I closed my eyes and checked myself out, trying to look for the infamous Clairvoyance which was supposed to be sealed off at this moment.

A few moments later a frown appeared on my face… its not there…

No memories of this are present either… there are many memories of Gilgamesh hedonistic lifestyle… it's quite something else.

The guy was a man whore before he got bored of females, more specifically he got bored of their utterly submissive characters.

After women, it was alcohol and food…

Thankfully I only have around 25 years of his life, around 10 years of hedonistic lifestyle…

'Uh...need to fix that someway… I can't allow this ego to take over and die, that is something Gilgamesh is known for.

Dying for being not serious.

I could only smirk feeling how pissed off a portion of me is when I remembered his unsightly deaths in Fate Stay Night.

"Hmm? Ah yes, the so-called plan which only worked for Kayneth and Waver. That needs some ironic out." Once I said that I got up on my feet and disappeared.

~~~~~~Moments Later~~~~~~

"I do hope you are not planning without me...Tokiomi." Gilgamesh appeared on the sofa, he was sitting on it with a golden cup in his hand.

"No, of course not. Your Excellency, we just received notification that Rider, Berserker and Saber has been summoned, this only leaves Caster yet to be accounted for." Tokiomi respectfully said that as he got up from his chair.

The head of the Tohsaka family did not expect that Gilgamesh will care about planning like this, he didnt look like someone who would care.

"Ah, the Caster class. quite annoying bunch. So do tell me that we have some sort of intelligence working since you have one of Masters working for you." The blonde King said as he looked at Kirei.

"Indeed we have been gathering intel for the past seven years." Tokiomi took his seat and pulled out some files from one of his drawers and handed over to Kirei who gave it to Gilgamesh.

The Ancient King of Mesopotamia skimmed through the files, there were several different expressions on his face before it settled on a smirk.

"From this, I can already guess which Servants are going to be summoned and by who." The blonde king said with a grin.

"Do tell us your thoughts, your Excellency?" The Tohsaka magus asked with a curious tone, he was interested in how King of Heroes was thinking, it would help him to understand his Servant more and form some beneficial cooperation with him apart from the base of Servant-Master relationships.

This was of course that Tokiomi wouldn't need to waste his Command Seals.

"Very well… let's start from the top. The Magus by the name Kayneth got relics From Macedonia and Ireland." Gilgamesh pointed at a picture of another blonde.

"There is only one notable Hero from Macedonia, the upstart conqueror who even went to my lands. From the legend I know of him he should be a Rider, most notably because of the Chariot he received in his legend.

Then you have relics from Ireland, the land known for its spearmen, they are the only ones worthy of some renown and to be summoned to Grail war." Gilgamesh said all that from looking at the piece of paper.

Tokiomi sweatdropped hearing that, he was slightly nervous, the King of Heroes should not know much of modern times.

The grail only provided bare bones of information on historical things that should be included.

So why the Mesopotamian King knows things beyond what grail should have provided.

'The legend of the wise king… but, he doesn't have Clairvoyance!'

"You do have quite a bit of information on the other two houses which created the grail ritual… both of these houses acquired relics from England.

We can safely assume the Saber Servant is either with Matou or Einzbern families." Gilgamesh said as he looked at other papers, these were information on Einzberns and Matou.

"From this, I gather that Einzberns got tired of losing three previous wars and they decided to hire an infamous mercenary, but that's where the issue lies." The blond King showed a picture of Kiritsugu Emiya.

"Issue? Do explain to us."

Tokiomi and Kirei attentively listened to what the Ancient Hero is going to say, especially the priest he is very much interested in knowing about Emiya Kiritsugu.

The blonde slightly sighed.

"If they truly got relic from England, the land which birthed first knights, then he will have problem in working with that Servant, this man would have better time with a Caster or Assassin, unless he summons Knight of Treachery either as a Saber or Berserker then they could have some sort of teamwork."

"Make sense one is a cold-blooded killer and the other is someone who follows code of Chivalry." The Priest nodded seeing the point.

"Indeed, I do hope they summon the 'Legendary' King of Knights, there is such possibility either from the Matous or Einzbern," Gilgamesh said with an almost excited tone.

"Now on more important matter at hand, do tell me how we going to keep this cooperation working with an another Master under wraps. I am sure there are some rules for this battle royale."

"Of course, Your Excellency. The moment the ritual starts Kirei will 'betray' me and send one of his assassins to assassinate me, this is where I will require your assistance in dealing with this threat."

The blonde Hero slighly frowned for a moment hearing that.

"I see, and you believe it will work? Make other Masters believe that assassination attempt in your home was real deal?" The Mesopotamian King said that before taking a sip from a golden cup.

"Your Excellency, you have a better solution for this?" Tokiomi asked him, now being not that sure himself.

"...maybe two ideas, one is that you been attacked outside your home somewhere in the city, Or being attacked just outside your house. To make it more believable or even confusing make it so that Kirei was there too.

Once the assassination is failure Kirei would flee…" The blonde Hero said with an almost bored shrug.

"...Very well, we can arrange it this way then."
