[Blood on the Rocks]

"As I have been summoned, Servant Assassin at your service, master."

As I kneel on the ground the words spill out of my mouth with no control on my part. I appear to be within a summoning circle in a classic Japanese room. Directly in front of my was my master, a purple clothed woman with purple hair and a hood.

As I rise from the ground and face my master she responds to my query.

"Yes... I am Servant Caster, and by the power of my command spell I order you to guard the gate to this temple and kill any servants or magi besides myself that attempt to enter."

I barely have time to widen my eyes at the surprise of being summoned by another servant when she begins speaking again and I can feel the chains of prana binding the command into my body and mind.

Letting out a soft grunt I manage an "Acknowledged." before having to move out of the room and to the gate that I have been tasked to defend.

-]l[-

I stood in the moonlight at the top of the stairs leading to Ryuudou Temple. My master had commanded me to guard the gate and even if I disagreed with the order, the command seal compelled me, and with how precise the command was, I was unable to disobey.

I turn to face down the mountain, and see a blue clothed servant running towards me. I watch her mouth move silently, before she moves into a ready stance before shouting up towards me.

"If I may ask, what class of servant are you?"

I let out a small smile before replying.

"Servant Assassin. I have been ordered to guard this gate and let no one pass. If you wish to pass through here you must force your way in (1)."

The girl stood for a moment. "Withdraw, I have business in the temple and none with you."

"I'm afraid I cannot do that. You may wish to make haste." I let out a smirk. "Your master's life may be at risk."

My opponent flinches at my words before readying herself for combat.

"One last time I ask of you. Withdraw and I shall let you live. Else I, Servant Saber shall be forced to kill you to save my master."

"Not a chance."

"Very well..."

And with that Saber kicked off of the steps beneath her and dashed upwards towards myself.

-]l[-

Artoria Pendragon, better known as Servant Saber was currently facing off with Servant Assassin as she fought for entry to the Ryuudou Temple, so she could rescue her idiotic master Emiya Shirou from being killed by his kidnapper Servant Caster.

"Very well..."

Saber spoke having just finished a conversation with her opponent, the Servant Assassin.

Launching herself towards Assassin, the clouds covering the moon finally moved allowing Saber to see what Assassin was wearing.

He was a slim tall man wearing a clean white suit with the arms rolled up, a white sleeved coat with the sleeves hanging out since Assassin didn't have his arms in them. The man himself had shoulder-length wavy black hair as well as a close shaved goatee. On his head sat a white top hat and on his shoulder was a pigeon that immediately took flight when Saber dashed at their perch (2).

Releasing a burst of prana from her body Saber launched herself towards Assassin as she readied her blade to attack.

Swinging the wind covered blade towards Assassin's neck Saber went to overpower the apparently weaponless servant and quickly move on to the temple.

Right after she swung her opponent crossed both arms in the path of the blow, and right before Saber's blade would connect a black coating slid up both arms protecting them from the invisible sword.

Rotating on one leg Assassin let out a vicious kick towards Saber and as she leaped out of its range a blast of compressed air sliced towards Saber who caught it on her blade and let her Noble Phantasm, Invisible Air take the brunt of the attack.

Recovering from the attack Saber lowered her blade to find Assassin disappearing in a blur of movement before reacting on instinct and turning to catch with her blade a black coated finger moving towards her body at high speeds.

Assassin leapt back away from Saber before kicking again midair and launching himself further into the air with just a small cloud of air indicating what had happened.

'... He just kicked off of midair...'

Activating Prana Burst once more Saber jumped towards Assassin who was currently keeping himself in the air via more kicks, and swung her blade towards his chest.

Expecting the block this time Saber attempted to kick Assassin in the chest, but right as she was going to hit him Assassin seemingly folded out of the way of her attack.

"Tch."

Saber continued her assault with precise jabs and swipes, but every attack missed Assassin as he folded his body and floated out of the way of her attacks.

A reprieve arrived for Assassin after ten seconds of Saber's assault, and Assassin was quick to take it as a chance to move a few meters away from Saber and prepare for his own engagement.

Crouching, Assassin let out a growl before his body morphed into a leopard that leaped at Saber jaws open.

Eyes widening in shock, Saber crossed her blade in front of her and caught the leopards jaws around her sword. Flicking the blade away from her Saber threw Assassin's leopard form away from herself and down the steps a few meters.

Just as Assassin was pulling himself up, an explosion was heard, and as both Servants turned they saw a white haired man land in a crouch near them holding a red haired teenager in a fireman carry on his shoulder.

Rising from the crouch, he spoke. "Saber, let's go."

Saber let out a tight nod before turning and backing down the steps alongside Archer as they moved away from Assassin who watched them leave before turning and moving back to sit by the gate to the temple and wait for the next intrusion attempt.

-]l[-

"What is your command, Caster?"

I speak from my position at the gate as my summoner steps towards me with her lover Souichirou Suzuki behind her.

"I shall be heading out with Souichirou-kun, don't let anyone in."

Letting out a grunt of irritation at her lack of trust in my abilities, which while understandable given my most recent encounter, was still irritating I nodded. "Of course."

I watched my summoner leave the area before moving over to my supplies.

"Hattori come," I spoke as I readied a cup of coffee to sip. "We have waiting to do."

-]l[-

"So how do you feel about guarding the temple, Assassin?"

I turn my head to view the man who addressed me, Souichirou Kuzuki before opening my mouth to respond.

"It is my job."

Straight and to the point is my response, and though most of the marines or pirates that I've given the response to were at least somewhat surprised, this man made no such indications, that he was at all surprised by my answer.

"I see, you remind me of myself if I had never stepped out."

Reviewing my knowledge of the man I nod once more. Kuzuki had been an assassin just like myself, however unlike myself he betrayed his organization and ran to Fuyuki where he became a teacher.

I found it reprehensible that he would betray his organization, though his skills were impressive for a human of this day and age. Nonetheless, he still disgusted me.

Souichirou made small talk with me for a few more minutes before moving on and leaving me to my post at the gate where I continued to wait.

-]l[-

It had been another few days before the next interruption to my routine came in the form of a golden armored figure advancing up the steps.

As he approached I could feel two things about him, the first being his power that indicated a servant, and the second his unmistakable aura of a noble.

Standing straight I shoo'd Hatorri away before brushing the dust off my suit and standing with my hands folded behind my back.

I had learned to be polite during the necessary interactions with the Celestial Dragons, but that didn't mean I had to like it, so it was with distaste that I greeted him.

"Good evening."

He turned to look at me before turning once more and continuing up the stairs to the temple.

When I made to step in front of him he simply pushed past me before speaking without looking.

"Do not push me, mongrel."

Letting out a growl at his condescending tone I once again moved in front of him before responding.

"I'm sorry to say that I must stop any servants from entering. It is an order from my master."

"... If death is your wish, then very well."

Instincts flaring I used Shave to dodge an attack that I sensed coming, and turning to view what happened I saw a Noble Phantasm embedded in the stone of the stairs. Right above the sword that I had dodged was a closing golden circle in the air.

"Enough mongrel, this is your last chance to leave before I kill you."

I'm silent for a moment before responding. "No thank you."

"... Very well then, Gate of Babylon!"

Immediately more portals formed behind him, and from them swords, spears, and other weapons slid out slightly before stopping.

"Die mongrel!"

The enemy servant, whom I was sure was Gilgamesh, swung his arm forwards before every one of the portals fire off their weapons at high speeds.

"Paper Arts!"

Using the 6th art of the Rokushiki, I slipped between each of the Phantasms as they flew into the ground behind me before dashing towards Gilgamesh with my arm outstretched.

As I prepared to use Finger Pistol, I was warded off by a series of smaller weapons flying towards me in succession. Daggers, rapiers, knives, all of them impacted either around me, or were bounced off by my usage of Iron Body.

Letting out a growl Gilgamesh proceeded to open up even more circles to the Gate, and began firing Noble Phantasms off at high speed towards me, even as they were firing, more gates continued opening up.

Slipping out of the way of the first wave of Phantasms I leapt into the air before using Airwalk to avoid the next few volleys of blades. I Shaved out of the way of one more blade before getting knocked back a few meters by the explosion, flipping in midair I landed against a tree before pushing off and launching myself in a parallel to Gilgamesh.

Dashing along the ground, I moved around my opponent before skidding to a halt and crouching, concentrating, I reach inside myself to the power as I access my Noble Phantasm.

"Neko Neko no Mi, Model: Leopard."

For the second time since my summoning my body shifted, but as opposed to my engagement against Servant Saber, this time I shifted into a half-man half-leopard form which granted me greater speed, strength, and endurance.

With my new form I once more moved towards Gilgamesh, this time in a low to the ground lope.

Sadly, even with my increased speed the closest I could get with within a few meters before more portals to the Gate of Babylon and thusly more projectile Noble Phantasms impeded my path.

As I moved to the side of this line I was stabbed in the arm by a spear that was fired from behind me. It seemed to Gilgamesh could form paths to his Gate at any position.

As I was preparing to attempt another engagement, both Gilgamesh and I stiffened at the feeling of blood lust in the air somewhere nearby us.

"GÁE BOLG!"

A red spear flew out of the surrounding forest towards Gilgamesh, and using knowledge from the Throne of Heroes I identified it as the Barbed Spear that Pierces with Death, one of the two Noble Phantasms for Cú Chulainn's spear Gáe Bolg.

Slightly panicking, Gilgamesh formed a line of portals between himself and the enemy Noble Phantasm in an attempt to block it, but as the weapons fired began to impact with the spear it didn't slow. Instead, if seeming sped up, freezing the mana in the air and arcing around everything in its way. (3)

The spear sank into Gilgamesh's chest, but I could tell from how it was positioned that the King of Heroes' great luck had saved him from a fatal wound. Despite this, taking such an attack would take great effort on the King's part and I took the opening this provided.

Using Shave to appear behind Gilgamesh I extended both my fists parallel to each other before coating them in my armament Haki.

"Six King Gun!"

Activating the final facet of my Six Techniques Noble Phantasm had all of my physical strength focused into my hands before being released into the King of Heroes' body destroying his already damaged internal organs such as the heart, as well as destroying a large portion of his armor. Slumping forwards, the King fell onto his chest dead before dissipating to the lesser grail. (4)

I turn towards where the spear came from to see blue clothed servant step out from the trees holding Gáe Bolg in one hand. Following Cú Chulainn were the other servants I had seen before as well as two people who I assumed to be their masters.

"You may have helped me deal with this irritating servant, but don't think that means I'll let you past me." I growl towards the group, still being in my man-leopard form. "If you want passed, you'll have to kill me."

Cú Chulainn stepped forwards with a savage grin on his face.

"Oh, I think I can arrange that."

Authors Notes.

(1) — A direct quote from the UBW fight between Sasaki and Saber.

(2) — A combination of the movie outfit and his normal one from the anime, designs take from wiki.

(3) — No, I don't believe that that is actually how Gae Bolg works, but it fit my purposes, so now it does.

(4) — Servant Death sends the servant to the lesser grail to provide prana to open the gate to Akasha, and thusly the body dissipates. To my knowledge.

I hadn't chosen who was gonna be Assassin till the fight with saber, so all I had to go on for those starting scenes was the thought. 'Huh, I imagine the wiki has information on what Assassin did during the war, and that would be easier to write then to brainstorm alternate paths to the three routes of a game that I have yet to play.' This OS thusly takes place in an AU to either Fate or Unlimited Blade Works.

And I mean, Gilgamesh is an easy guy to work into any story, plus he plays a pretty major role as an antagonist (tmk) in Fate and UBW. Since those are the ones that I know you'll probably see him a bit more until I either actually play F/sn, or learn more about Zero/Apocrypha/Extra/Kaleid/Ataraxia/Grand Order.

It's been a few years since I last watched or even read One Piece, so don't expect amazing characterization, but I did what I could remember (nothing) and took the rest from the wiki. Thusly I care immensely about whether or not I got his Lucci's characterization right /s.

This chapter was made to practice First Person, as well as fight scenes. Lemme know what you think about the chapter/character sheet. Please don't suggest people since I'll have no idea who you're talking about and will feel bad, and enjoy.
