Just a little thing I thought up. no idea when I am going to upload.

Oc Gets reincarnated into Jack Horner from PIBTLW , Due to jump chain, and shenanigans the world is a crossover.

You've read the title, this is Caster route. What would have happened if that night the one to save Caster had not been Kuzuki, but Shirou Emiya? Just how would Shirou change at the discovery of the Holy Grail War? How would Shirou change Caster? And how much would someone like Caster change Shirou? (Good End- Finished. True End- Work in progress)

If Emiya summoned as a Berserker in the Fourth Holy Grail War by Kariya. Thing goes out of control pretty fast, well, not like he cared anyway.

Alaya is gone. The Counter Force is gone. Without them, the Throne of Heroes released all the Heroes on Earth against the planet's will. When Gaia sensed that the World is on the brink of collapse, she sent its First Hero to fix the mess. Now, Shirou Emiya has to save the day once again. What can a Retired God, a Treacherous Knight and a Boastful King do to save the planet? [AU]

Counter Guardian Emiya is a man of many regrets. Among them, the fact that he wasn't able to save his Saber when he was a boy continues to haunt him to the end of days. Now, however, a chance has mysteriously appeared to change that result. And being the practical man he is, he will not hesitate to seize it. But still... why in Alaya's name is Artoria his new Master in this world?

"People come and go, but magi are just fated to meet each other." - William Brown, a depressive prick of a human being who has lived his life without purpose, unwittingly gets embroiled into the Fifth Holy Grail War as the eighth Master. With unearthly and bizarre forces teetering at the edge, will he persevere and grow... or give in to his desire for power? (has X-Over elements)

[Rewritten] News flash! I'm a dude from the 21st century with amnesia, somehow reborn into some baby named Iphicles. Oh, my sister is named Alcides by the way. What can possibly go wrong?... I hate my life. (Reversed gender; Big sis Heracles, young brother MC, Not a Self Insert, pre-Celtic Myth Scathach, NO Harem)

In December 1999, a war is about to begin. Not a normal war, but a war between masters and servants. Saber. Archer. Lancer. Berserker. Rider. Caster. Assassin. This is the second Tokyo Holy Grail War. The main character is Ayaka Sajyou, a young magus fighting her way through the grail war with her servant, Saber. This is going to be based off of the Fate/Prototype short.

Minamoto no Raikou x Quetzalcoatl Yuri Lemon One-Shot: After hard work, comes a well-earned vacation for Raikou and Quetzalcoatl. That it involves shenanigans and passionate lovemaking is just a bonus. Read, Enjoy, Review!

Nosh, faithful guardian of Abigail Williams, is lured to Chaldea's basement by a presence even he doesn't understand. What mysteries will our feline hero uncover in The Great And Terrible But Beautiful Murasaki Shikibu Library? And how will he cope with the expectations of cats set by human films and literature?

A new set of servants in the original Fate Stay Night. The Holy Grail War has been altered from how it is supposed to go. Only one Servant realises this as things slighty, but rapidly change.

A different upbringing, one meant to prepare him for what was to come. With the sacred scabbard embedded in him, the young man summons the Once and Future Kings. Wait, kings? As in plural? Seven kings? How is this fair?

If EMIYA's future self told him Alaya ordered him to take a vacation with his fellow Counter Guardian—Okita Souji Alter, he wouldn't believe him and probably fire a Caladbolg II for that poor joke. Jokes on him, he'll be living in a house with Okita too!

As the hit new boardgame FGO Duel spreads throughout the populace, Ritsuka, Shirou, and Hakuno find themselves joining in with the craze. As Ritsuka comes across a figure that should never have existed, though, the dark truth behind FGO Duel's existence will draw all three into a game far more deadly than they expected. Heed the cry: "Duel, Go!"

A Nasuverse fanatic was born with a Gamer system in Ancient Babylonia...as none other than the gold demigod. His end-goal? Become the Greatest Hero, get summoned, and make Artoria his waifu. His inner-Gil definitely approves...Misunderstandings and Bullshiting are necessary sacrifices. (Semi-Gamer, eventual Fourth Grail War)

An adventurous idiot made a Blood Pact with the Beast of Calamity (Fou), Don Quixote style. GAIA developed conniptions. Fou! (400AC Britain, Proto Merlin and Lancer Artoria, Primate Murder!Fou elements)

Blood debt, paid in blades. Sins of murder, paid in blood. Impulsive abandonment breaks everyone. For her father who has forsaken her, for her mother who has cursed her into doom, when her own destiny fated her to fail... who will grant her redemption? Surely, not herself?

Ushiwakamaru was a sword with no sheath, too sharp to keep after the fighting was done. Still, she had been called, and she would do her best. She had never known how to do otherwise. Fujimaru Ritsuka put on a brave front, but he was a mortal caught in a war of demigods. Still, people were counting on him, and he would do his best. That would be better than giving up on them.

He decides on applying for a job in the security organization as a magi order to make an earning from an "actual" job and sticks to his codename Nexus. The least he can do is to get some job done rather than laze around. However, something his coming for him and his life might turn something more "unnatural" than usual. OCxHarem

Shirou Emiya, born to a Clan following the name they had not officially been called in centuries, chasing after a dream created by their ancestor as relentlessly as any other Magi family reaches for the Root.
