This is going to be for one shot side stories or Omake's of things that are not apart of the actual Princess of Knights story, may include crossovers with other series outside of fate:zero/stay night and harry potter.

The 1st one being Gilgamesh x Arturia Potter-Pendragon pairing.

Enjoy, oh and please note i'm not that good with battle scenes.

{Line Break}

Arturia glared at the Arrogant and smug smirk on Gilgamesh's face the 19 year old teen wondering how the heck he was still around after the 4th grail war.

"Well you act so much like Saber it's amusing that you fight me but you will become my queen" Gilgamesh says with his infuriating smirk in place as Arturia switches from her civilian clothes to her armour while summoning Excaliburn as she did not plan to submit to the arrogant king in front of her.

"So you with to fight me to the very end do you?" Gilgamesh states as he brings out one of his treasures to actually engage the princess in front of him in actual combat as she was worthy of that much at least.

"I don't know how you're still around but I am going to end you" Arturia says as she charges at Gilgamesh who parried her strike all the while smirking at her.

"Once I win you will become my queen and rule by my side" Gilgamesh says as he parries Arturia's strikes as despite being very good for a human Arturia didn't have the advantages or boosts that Gilgamesh had by being a Heroic Spirit and every now and then he would lash out and attack Arturia just to keep the fight interesting, Plus he did need to break her of her rebellious attitude towards him her future husband and king.

Arturia was getting tired she had been fighting the arrogant jerk for well over an hour while going all out and he was barely even showing any strain from the fight.

"That does it i'm going to end you right now!" Arturia shouts in anger and frustration as she starts charging her blade with mana from the world around her but instead of glowing light like Excalibur, Excaliburn gained a white flame like aura before she unleashed her attack at Gilgamesh "EXCALIBURN!" as sea of white flames could be seen as she unleashed her attack on Gilgamesh who was forced to use his strongest fortress class treasure to survive the attack, And when it was over Arturia leaned against her blade panting in exhaustion thinking she had wiped out the jerk only for Gilgamesh to appear in front of her singed but still okay although he was annoyed the attack got through his treasure enough to actually cause him damage.

"I win my future queen" Gilgamesh says as he picks the exhausted princess up he had his queen and now he had to rebuild his kingdom for after all the world was his garden and he would rule over it once again only this time it would be alongside his new queen, once he removed her rebellious attitude against him that is as it would do for his queen to not be loyal towards him.
