Not as Planned

Underground

After the light disappear, smokes appeared. However, it's not thick enough to block someone's view.

Tokiomi Tohsaka, who have just used the fossilized skin of the first snake as a catalyst to summon a Servant, is looking through the smoke to see his Servant. However, he sees nothing.

"There's...no one?" Said Kirei Kotomine as he also looks at where Tokiomi looked.

"There's someone."

Everyone in the room looks around, trying to find the person who spoke that. It's not Tokiomi, or Risei, or Kirei.

"Down here, mister."

The three of them look at where the summoning circle is. This time, they lower their vision. On the circle is a little boy with golden hair and crimson eyes. He wears what appears to be an open white overcoat with brown trims at the edge, revealing his bare chest, a necklace with one circle and four leaves, and a white shorts.

Tokiomi looks at the boy with shocked expression. From what he wears, Tokiomi knows that the boy in front of him is not from this age. Perhaps millennia ago.

"Are you...the King of Uruk, Gilgamesh?" Ask Tokiomi who is still shocked.

"Yes, I am. You're a smart man, Master." Said Gilgamesh with a smile.

Tokiomi is trying not to facepalm at what have happened. Apparently, he managed to summon the Servant he wanted, Gilgamesh. But he never anticipated that he's going to summon the King when he was a child!

Gilgamesh meanwhile, look around at the place he's summoned at see the skin of the first snake.

"Hee, so this is where it ended up." Said Gilgamesh as he approaches the skin.

"I guess it's yours?" Said Kirei as he's also shocked, though he's better at hiding it.

"Yes, this is one of my best treasure! However, I lost the skin when I had a journey. That's why after I grew up, I make sure to guard my treasures better!"

Tokiomi can't hold it anymore; he facepalms. No wonder he summoned Gilgamesh as a child. Though he wonders why a child. After all, Gilgamesh managed to reach adulthood, so he should be summoned as an adult.

Gilgamesh knows the reason for his Master's facepalm. However, he does nothing but smile at what Tokiomi did. Thanks for having the skin of the first snake when he was a child, Gilgamesh can somewhat choose how he's going to appear.

There's no way he's going to appear as his jerkass adult form. So he decided to take the form when he was a child.

The other reason must be because as a child, it's natural to think that he's weaker than when he was an adult. That's true, he lacks sufficient magical energy to summon a large amount of Noble Phantasms from the Gate of Babylon.

But he has something to compensate that.

But he's going to leave that for some other time.

Gilgamesh runs towards the stairs as others are just looking at him. Midway walking though, he trips himself and falls back to the bottom. As he rubs his head, he knows that he now looks quite weak.

Tokiomi is now trying to prevent himself from ramming his head to the wall. What he had done to deserve this?

Later...

"And when that happen...Your Highness, do you hear what I said?"

Tokiomi is currently explaining his plan to Gilgamesh. Although he's a child, he must have something during his childhood that makes it possible for him to be summoned as one.

Tokiomi begins to doubt that.

Gilgamesh is currently watching TV while eating some sweets; candy, chocolate, and so on. He's so focused at the TV that Tokiomi doubts that Gilgamesh heard what he said few minutes ago.

"So humans finally created a means to travel through air, eh? Impressive. Though I don't know does it makes today's humans better or not than during my time. They have good and bad." Said Gilgamesh as he eats a candy.

Tokiomi Tohsaka is a prideful magus. Maintaining dignity is a must for all magi. But this situation makes him wants to roll on the floor and cries.

Perhaps it's not too late to...

"Yes, I heard what you said, Master. Kill Assassin, Mr. Kirei will take sanctuary at the Church, and no one will target him. In reality, there are still many Assassins. Short version; we can spy on other Masters and Servants without being suspected." Said Gilgamesh.

...on second though, there's still a chance. He's going to take it.

"Master?"

"Yes, Your Highness?"

"Do we have any information about the other Masters?"

"So far, we currently have two – one for each – if we exclude Kirei."

"I see. After the first phase is done, order the Assassins to focused more on the Master of Saber and Lancer. Logically speaking, as Archer-class Servant, I can win against Saber but must be very careful with Lancer."

"Of course, my King. Fear not though, no matter what kind of heroes they are, they are no match for..."

Tokiomi stops his talk as Gilgamesh gives him a glare. The King of Uruk shows that he's quite displeased with what his Master said.

"Don't have that kind of confident, Tokiomi. That kind of confident will bring nothing but destruction to you." Said Gilgamesh with a cold tone.

Tokiomi feels a sweat is appearing at his forehead. He closes his eyes and bows.

"Forgive me, Your Highness. I assure you that I won't do that again."

"Nice to hear that." Replied Gilgamesh with a smile.

Few days later...

Tokiomi is walking around the living room. He had found out that Gilgamesh has disappeared. To make things complicated, he didn't tell him where he wanted to go. It's almost the time to execute the first phase of the plan.

A door suddenly open. When Tokiomi look there, Gilgamesh is entering the room and then close the door.

"Where have you been, Your Highness?" Ask Tokiomi as he tries to suppress his annoyance.

"Just taking a walk. During that, I found an orphanage that almost went bankrupt." Explain Gilgamesh.

"What happened then?"

"I decided to give them some donation. Should be enough for a decade. The children there then asked me to play with them, calling me 'Big Brother Gil'. There's no way I say no." Gilgamesh then has a little laugh and is now smiling.

Tokiomi can only sigh as he heard that. Of course Gilgamesh would do that, he's a child after all.

"It's almost the time for the plan." Remind Tokiomi.

"I know, Master." Replied Gilgamesh with serious expression.

At night...

Just as planned, Assassin managed to walk through the "security system". He's now approaching the pedestal where the gem is; the gem that powered the system.

Assassin puts his hand at the gem. Suddenly, a big explosion erupted at where he stand. It's obvious that he's killed.

Rooftop

Gilgamesh looks at the scene as he sigh. He sits with an over-sized crossbow – at least for him – at his side. Usually, he just send a weapon directly from Gate of Babylon. However, there's a chance that a Master is watching the mansion. There's more than one way to spy on something. So he decided to hide it as long as he can.

That, and he's in mood to use one of his treasure.

Tokiomi's Office

"Currently, we're spreading the words of the demise of Assassin. That means the first phase is over."

"I see. So now, we do nothing but wait until more information comes from other Assassins."

"Right, my King."

"Say, Master. Can I ask you a question?"

"You can, Your Highness."

"What is your with for the Grail? I am pretty sure it's pretty big that the Grail decided to choose you as one of the Masters."

"My wish? I want nothing more than being able to reach Akasha."

"Akasha, huh?"

Gilgamesh stands up from the sofa and walks outside. For now, the chances of him or Tokiomi do something big are quite low. Meaning that he has some spare times.

Perhaps he should visit the orphanage and play with the children there?

And it's done.

I got inspired when I read a fic about EMIYA being summoned as Archer of the Fourth Holy Grail War. So I think, "What if Child Gilgamesh being summoned as Archer of the Fourth War?"

So, what kind of changes do you think will happen that, instead of the usual Gilgamesh, this War has Child Gilgamesh as Archer?

If you have question or suggestion, feel free to tell me.

Review please.
