Y/n Pov:

For once in a very long time in such a long time I wanted nothing more than to kill her. For believing in fathers lies, I pull my sword out and was about to attack and she got her ready. Both of our swords are close to each other's necks. 

Y/n: "HOW THE HELL ARE YOU STILL ALIVE?!?!"

I have never felt emotions of sheer rage and anger and hell even yelling is new to me. In a long time.

Artoria: "I was also cursed sister as well. The sword caliber was destroyed but thanks to Merlin, he gave me Excalibur do to him making it in Avalon. He used the magic there to stop my aging whereas you were cursed by gods themselves."

Y/n: "I hate you."

Artoria: "I know but sister you must know father lied to me for so long about you being evil. I'm sorry."

She puts her blade down I was about to cut her and when I did the blade could not get cut her or even bleed.

Y/n: "What?!"

She grabs a golden blue scabbard.

Artoria: "He used Avalon's magic into the sword and used the concept of never dying by any means in my scabbard. Meaning I can only die to age with my sword but no harm to me can do such a thing."

Making her like me bleed and it goes away arm cut off a new one would be made by the ether itself.

Y/n: "Why are you here to haunt me? scare me."

Artoria: "None of the above. I just wanted to see my little sister."

I stab her in the stomach I pulled it out and she was good like nothing ever happened.

Artoria: "Sister please."

Y/n: "You should have thought of that when father exiled me from the kingdom."

Artoria: "I know but I was learning I was training. He told everything about you, and sense he told me a lie about you. Running away after a failed assassination I just believed him."

Y/n: "Tell me then how did you know he was lying."

Artoria: "It was after right when I felt the world shake."

The world shake meaning when I pulled Rhongomyniad.

Artoria: "When I was taught by Merlin, he told me how to read the stars and I saw a future outcome were if I did not talk to father, he would have caught you and have you hanged. I questioned him non-stop. When he screwed up his words about you making a potion about ageing. You wanted to make a potion for father so he can live longer and praise you. When he slipped up, I looked in his study and found a death potion from him. A plan to have you exiled father wanted you out for so long so I can focus on being queen of Camelot. I'm sorry sister."

As a few tears came from her and she hugs me even though I hate her. Even though out of sheer instinct the blade goes through her stomach again. Not caring it was there she just hugs me out of sadness and happiness. Knowing this I hated it even more I hated this feeling of comfort from someone I have not seen in such a long time from my age and time. It was not my daughter not my knights. It was the one person I hate most who loved me most. Of all people of all times, it was my sister.

Natsu Pov:

I was at the guild with the rest of the gang. We were doing a celebration of our victory against the twin dragons. But Gajeel wanted to check something out and left us.

Gray: "Hey stick breath were is out other winner?"

Natsu: "What was that you Frozen woman."

Gray: "You want to go flame princess."

Erza: "Enough you two."

Gray&Natsu: "Yes sir."

Erza: "We all did a great job today we got tomorrow and if Y/n can beat the golden man we are sure to win."

Makarov: "I would not think so she will have to go all out to beat him."

This caught everyone's attention.

Makarov: "That man is not right something is wrong with him. He seems normal but his magic no his whole existence scares me. More than Acnologia I sense that man the golden man is more of a threat then Acnologia."

This caught everyone off guard to hear gramps fear someone like Acnologia is understandable, but he only saw that man once and was already scared of him what makes him such of a threat?

Natsu: "Nah don't worry gramps Y/n will take care of him and besides when I think of it I only spotted him once in that guild awhile back when I attacked that place. He did not move he must have been scared of me or something."

Makarov: "Natsu how do you kill a dragon without dragon slayer magic?"

Natsu: "I don't know?"

Erza: "He means by this Natsu we all know your strong here but. That man has something even I don't have, that man when I first saw him his magic was that of a god slayer magic or something."

Natsu: "Well gods can be surpassed sometimes."

Makarov: "No Natsu you are not wrong but that man, he does not only have god slayer magic, but he really has magic like Erza's."

Gray: "How can you tell gramps?"

Makarov: "I can't just more like a gut feeling. It's a run or flight type of thing and when I saw him, I wanted to leave that arena with you kids, but I did not won't us to lose. So I sucked it up and let it be."

Mavis: "You are not wrong that man he saw me."

Everyone: "WHAT?!"

Mavis: "That man is no normal person he's someone who can destroy us all. When I felt his gaze upon me. I felt like he could kill me in that moment. And I can tell he wanted too as well."

Lucy: "What the heck is wrong with that guy why would he want to kill you and how can he see you and hurt you though?"

Mavis: "Easy he is someone from the age of were dragons were commons as grass and gods can walk the earth whenever they wanted to."

Erza: "You mean he is from the era of mythic times?"

Mavis: "No the age of gods that man I've read about him when I was normal. That man has powers to attack even the spirts themselves and all sorts of weapons. Erza he is the one who founded your type of magic, his name is Gilgamesh."

Gray: "Gilgamesh never heard of him?"

Natsu: "Same."

Lucy: "I've heard of him he was told to be a monster back in his time. Women money anything was his, the land we step on was his. He even killed a powerful demon with his friend. Gilgamesh is told to have every treasure in the world."

Makarov: "You are right Gilgamesh owns the ideals of that very thinking, Erza the weapons you have is the weapons he has but more powerful sense they are the original."

Erza: "What how?"

Makarov: "Easy generations learn from the masters to make weapons that we see day to day. Meaning it all comes from him the golden king Gilgamesh himself."

Natsu: "Well I don't see any problems then we can beat him he has god slayer magic and such. But that does not mean he is able to be surpassed right."

Lucy: "I would not think like that Natsu he does have god slayer magic but his weapons are also dragon killers' demon killers and so on."

Natsu: "WHAT THATS A CHEAT CODE IF I'VE EVER HEARD ONE."

Mavis: "It is and it's beyond unfair he can see spirits and see past illusions. Gilgamesh might be the most powerful person on this planet."

As we were all shocked to hear this the doors opens to him.

Gilgamesh: "Hello mongrels."

As we all looked at this golden jerk.

Gilgamesh: "I'm here to see if any of you would like to have a drink with me before I defeat your ace in the hole Y/n."

As he sits down at a table and opens a golden portal with wine coming out of it and cups and he just sits there waiting. I was about to attack him until.

Makarov: "Hello Gilgamesh is it okay if I call you that."

Gilgamesh: "You may mongrel for I've been in a good mood lately."

Gramps sits across from him.

Gilgamesh: "You mongrel girl the little fairy girl I can see you sit with us."

As Mavis was scared out of her mind that someone out of the guild can see her like that. How is he doing this. Mavis slowly walks over towards them.

Gilgamesh: "Hurry up before I cut your eyes and pull your heart out."

She was scared about hear that and does so.

Gilgamesh: "Hehehehe now that's better tell me you two why were you talking about me."

I wanted nothing more than to kick his ass.

Makarov: "Well if it's okay with you can we speak?"

Why is gramps asking to speak this is making us look weak why gramps come on take charge of this.

Gilgamesh: "You may child."

Makarov: "I wanted to know what Y/n was facing before her big match."

Gilgamesh: "Ah I see then well you better be smart with your words before I cause this world to become nothing but ash. You may only speak of me in front of me not behind me like a shriving coward curled up from the cold. Wanting to know when this winter will end. Speak in front of me not behind me ever again."

I've had enough. I jump over about to land my iron fist but, in that moment, I was sent flying across the room. With a chain wrapped around my hand I broke out of it, but another comes, and I try to burn it, but nothing happens to it as it grabs me by my foot this time. Throwing me around the whole place nearly destroying where our guild was resting up. As I was being thrown around everyone tries to fight back now but were easily destroyed. Erza's armor was destroyed like it was paper Gray's magic destroyed like nothing I've ever seen before. Lucy's sprits were all beaten so badly she couldn't summon anymore.

Makarov: "STOP THIS AT ONCE EVERYONE!!!!"

I was badly hurt felt like my ribs were broken.

Makarov: "I'm sorry what they tried to do."

As gramps bows in front of this jerk.

Makarov: "Please forgive us."

He was getting on his hands and knees to just keep us safe.

Gilgamesh: "........Next time mongrel teach how not to brag in someone else's talks. I wanted to speak about Y/n right after I told you not speak about me behind my back. Seems it was a waste of time to speak such lowly cur."

As we were all down and looks at me and points.

Gilgamesh: "Be happy you have such a lovely master."

As he leaves us.

Y/n Pov:

I was with my sister, and we were looking at the moon together no words it's almost been a whole hour sense we last talked now and to be honest it was starting to feel even more stranger then usually.

Y/n: "I'm going back to my guild."

Artoria: "I-I see."

Y/n: "Well it was nice."

Artoria: "Yeah hey sis."

Y/n: "Ye-Yeah."

Artoria: "Is it okay if I can sleep were you and your guild is at."

Y/n: "You really want to spend more time with me."

Artoria: "Yeah."

.......

Y/n: "No it would be too strange to say hey guys this is my sister from such a long time ago. I don't won't them to ask about it how about this then we go to a hotel, and we can rent a room together and we just hang out there."

Artoria: "Sure I would not mind that."

The guild would be fine without me and besides I hurt some of them because I was pissed off. We made it to a hotel and we just did not say a word to each other just us quite to each other until I broke the ice.

Y/n: "What happened to Camelot."

Artoria: "Gone like your kingdom but I was betrayed by someone I trusted most."

Y/n: "I see....."

Artoria: "What of you."

Y/n: "Attacked lost because of a slip up on my part."

Artoria: "I see...."

Y/n: "You remember those times when you made the blue dye rocks."

Artoria: "Yeah I like the color of blue because it reminds me of us."

Y/n: "How so?"

Artoria: "Blue for you and golden for me. The blue to keep me happy and safe and knowing you were always by my side and the golden to keep me strong and powerful. And when you and I were always together we would be unstoppable."

Y/n: "I......I like that ideal."

Artoria: "So did I Merlin liked it as well sense it was a nice color to represent us both."

Y/n: "Thanks sis but you know I'm still mad at you."

Artoria: "I know I am as well for believing father's lies. Y/n I heard you've gotten better at magic can you show me some of yours's I wanted to see your magic for so long."

Y/n: "You know mine is dark magic and its ugly and taboo."

Artoria: "Matters not sister I always wanted to see it for so long please I bet it's pretty please."

I sigh to myself and start to make a blue and dark flame showing her it and she was in awed by it.

Artoria: "It really is pretty I knew it."

Y/n: "You're just trying to be nice."

Artoria: "No I mean it sis your magic is gorgeous I've only seen dark flames like the god slayer flames and I've seen all types of magic, but your dark magic is really pretty you know magic also reflects one's soul right. Meaning your dark magic is pretty making my little sister pretty as well not ugly."

I blushed from the ideal and look away.

Artoria: "Wait are you blushing."

Y/n: "................No"

Artoria: "You are awwwww my little sister is blushing."

As she hugs me and just snuggles into my face.

Artoria: "I miss this were you and I got scared by something and we will always come to each other's room. And sleep with each other until one of us wakes up."

Y/n: "I know I do sometimes as well, but sis can you sleep in your own bed please I'm-I'm trying to process all of this still."

Artoria: "I understand please have good dreams sis love you."

As she goes to her bed and started to fall asleep while I say nothing to her while I just think to myself wondering what am I going to do.

(Yeah, more story progress development with Y/n and Artoria Gilgamesh vs the guild more like a one-sided slaughter fest. I wanted to make this more of an emotion rollercoaster not like sappy stuff more like holy shit this is a mid-life crisis type of shit. Anyways tell me wat u think as always omage1 out peace.)
