Hakuno Kishinami sank deep into the depths of the Moon Cell Core, but as she wished to end the Holy Grail War, the Moon Cell sent her suddenly into a black room contained in a separate virtual world. Now, Hakuno battles against both the Cardinal System and Akihiko Kayaba in cyberwarfare for the fate of Sword Art Online's players. Unfortunately, they aren't the only concerns.

The Moon Cell was the most advanced AI ever developed. In the 4 billion years that it had been around, it had known that it was well and truly alone. The only one of its kind. At least, until it slid into one universe where that wasn't exactly the case. Sure, it might not have been as powerful as it was, but what sort of adult would it be if it didn't take care of a child?

Noble Phantasm, the crystallization of a hero's legend, and of their identity. As the servants of sword and magic clash, the Hero of Aincrad must reveal the true name of his Noble Phantasm. But it's more than a mere weapon, it's the purest reflection of a heroic spirit. So what will the Treasured Tool of Kirito will reveal?

The Holy Grail War. A terrible event that killed hundreds of people when the Holy Grail was unleashed 10 years ago. And now a new Holy Grail War is beginning and this time, Rin Tohsaka will be participating. However, the Servant she managed to summon is quite unusual. Just who is this Dark Swordsman and what effect will he have on the war?

While analyzing the beta testers during the last few days of the beta test, Akihiko Kayaba discovers something strange. He checked once and then twice. There was a total of a thousand beta testers selected from the hundred thousand. Then why? Why was there an extra person?

Kayato Mizukè has died after making the world filled with his light of entertainment, people cried for him. But to him he has to restart a game from the beginning. Au Earth, OC-Shiro Shirou!Harem OC is Shirou Emiya!

Summary [Slow updates] What if fate had changed and Shirou had a brother? But even the slightest ripple of the water could cause a wide one. As the grail wars began, Shirou slowly discovered the gruesome secrets Kiritsugu hid from him all along.

Emiya Shirou being a counter guardian is bad enough. Being stuck in a death game with a weird system is worse. That was when he encountered a certain boy, who was sinking in his past. [One shot, crappy writing expected] [M/M]

A new challenge has emerged in Alfheim Online, the Holy Grail Tournament. Whoever wins will obtain the ability to make any one change to the game they want. Who will emerge victorious?

Shirou Emiya después de derrotar a Gilgamesh es absorbido por un portal que lo lleva a un lugar desconocido. Allí conoce a una persona que lo reencarnara en un mundo diferente al suyo. Pero como la suerte de Shirou es E, tendrá que lidiar problemas y luchar por su vida en un juego de la muerte. Shirou UBW!. En el futuro OP.

just a plot bunny I had

A Simple Story where Shirou summon different Saber. Disclaimer: I do not own both of the franchises except OC. Intended to become a crack story with some seriousness.

The first VRMMORPG, Throne of Heroes Online, has been released worldwide and already has more than 10 million players! The players are already battling legendary monsters and deities as they try to be the first to claim the Holy Grail. But the danger of mythological earth becomes deadly real when the players are trapped in a death game, as great heroes and terrible villains arise.

Twenty years after the fifth grail war the grail activated again, marking the start of the sixth war. As the last Tohsaka, Rin was determined to once again prevent disaster with Shirou at her side, and a recently freed Kirito receives an interesting proposal from a friend.

Inspired by "The Hill of Swords" by gabriel blessing, this is a crossover between more than Fate/SN and SAO (but the tags, you know...), where seven "swords" go to another world after their death. Also, lots of memes and serious business, because I'm like that. Main characters are : Shirou, Kirito, Ulquiorra, Kaneki, Ascheriit, Alexander Anderson and Clare. And others.

A series of one-page omake snippets from my story "A Swordsman's Holiday" where Kirito gets thrown into the world of fate/stay Night as Servant Saber, and hijinks ensue. Pre-written omakes have all been posted; will now update sporadically whenever inspiration hits.

Takes place after the 5th holy grail war. Arturia gets the choice and stays forever with Shirou. After, that a few years later another Holy Grail war begins. Old friends and foes meet again. More servants appear other than 7 normal ones. An unknown servant and a new master. (ShirouxArturia, OC, and of course AU). M just to be safe though.

Post-SAO, Klein finds a new apartment. His new neighbor is good at cooking, and though Klein would happily try, he can't actually live on pizza indefinitely.

Au, three ways crossover with Sao Fate and Harry Potter. A grail war in Tokyo changes the lives of two children, truths will be revealed, dark secret exposed. Magi wizards and technology, the world will never be the same.

The regret is still there, countless times trying to undo what's already done, all end up in failure. Sometimes, heroes do need to be saved too. [Sorry for bad tittle and grammar, Beta is Welcomed] [Female Kirito]

Lisbeth hears an intriguing rumor about another high level player who's not only a good Blacksmith but seemingly possesses a unique skill. So of course she's going to go check it out. The player she meets is not what she is expecting though. Implied ShiRin. One-shot for now, but may become a multi-chapter in the future. SAOxFSN!

Don't worry the chapters are written in english. If you can read this summary without google translate, Congratulation you may be a billingual/multilingual 「聖杯」その言葉は珍しいがない。聖杯を獲得ってために、七人マスターがお互いにを戦う。その戦いは「聖杯戦争」と呼ぶ。各マスターは7つの異なるクラスを召喚される、そのクラスはアーチャー、ランサー、セイバー、ライダー、キャスター、アサシン、そしてバーサーカー。最後の聖杯戦争はセイバーの勝ち、だがその聖杯はもう破損した。セイバーと彼女のマスターが承知した。それはもう聖杯じゃない、令状を使ってでセイバーが聖杯を破壊した。今、もうはや聖杯は存在すべきではないはずだ

Ilya likes to play video games, and in the time she has remaining, Shirou is more than willing to play the new VR game with her. But when they are trapped inside the game, [Sword Art Online], they determine something even more distressing: Kayaba Akihiko is definitely a Magus.

Here's a little idea: Fate/Extra happening after Sword Art Online. Read to find out more.

It was supposed to be a simple trip to visit Sugu's dad's sister. What they didn't expect was for Kazuto to 'die' and for him to lose his memories and become Kazuto Emiya.(CHALLENGE)
