The Force works in mysterious ways. It brought two boys together to become unlikely brothers. One strives to be a Hero of Justice, while the other comes from a galaxy far far away... The Fifth Holy Grail War is in store for a darker side of the Force.

He lost everything, being sent into a new world in a brutal clash. Years later, Fuyuki’s Grail War has gotten out of hand, and when there are those who would stand up to go after his loved ones, he would stop at nothing to keep them safe. After all… was there any man alive who needed a reason to protect his children?

An experiment gone wrong, or possibly right? A nascent Kaleidoscope opens his eyes. A Fate/DxD/Multicross story. Thanks to TheMadLad for the cover image.

In the broken world of Remnant, a shadow war that has lasted for thousands of years rages on. But when mysterious spirits begin arriving on the planet's surface, the world and it's people must confront the truth about their genesis and the plot of the forces who brought about it. Note: Siegfried tag is not for Siegfried, but Sigurd, because there isn't one for Sigurd.

Rin Tohsaka travels to Academy City to participate in the Fifth Holy Grail War, in order to win the Grail and fulfill her father's legacy. After meeting with a certain unlucky Level 0, she finds herself in an entirely unorthodox conflict, where the rules are utterly broken, and the world of Science and Magecraft collide. (Full Type-Moon/Index Crossover)

Shirou is sent to a new realm thanks to Zelretch armed with a Servants class card deck how will Shirou react knowing that his dad alive and a god.

Life was incredibly boring and repetitive, that's at least what Luka had been feeling for the longest time. Though when he went for a walk in the park and witnessed the supernatural for the first time, he was forced to awaken a power he didn't know he had to survive. Safe to say, for the first time since he was little, life was finally looking interesting. OC x Small harem.

Fate is a weird thing, you can try to escape it but it always catches up to you. So how does one decision change the fate of the world? what if one action was able to change the fates of two groups in their entirety? Let's see what happens when Hollows and Shinigami clash with servants and masters fighting alongside the reapers that protected them in their most dire hour.

It was supposed to be a simple experiment, one which Rin had done many times in the past. Yet here he was... What went wrong? Why was he faced with an endless horde of monsters? And was that a magical girl? Shirou hoped his day wouldn't get any worse.

In which Shirou and his ladies wind up at Chaldea as the facility's newest cooking staff on D-Day. WARNING: Mature Themes Abound!

Singularities. Points in Human History which have become corrupted with the presence of a Holy Grail with the end result being the incineration of Humanity. However, it is not the Grails alone which are divergent. The Incineration comes about as one world in particular comes to an end. The two become linked as figures from a different Throne reach across the barriers between worlds

Kamui, a fighter from the 6th Holy Grail War, wakes up in a park of Tokyo after an intense skirmish. How long will it take her to understand that she is not home? And how will she adapt without money and ID?

Guardian, Protector, Hero, and perhaps something more, that was what he had always meant to her, but to others he was simply known as the Huntsman of Red, Remnant's final hope.

How would the world of Fate and DXD change if the two worlds were the same? How would the story of Fate change if a certain Red head was related to a clan of red headed devils? What would change in the tragic and bittersweet world of fate and what tragedies would still occur?

In a world where all can be real, what does it mean to be human? What is the meaning of humanity? A meeting between a human and a devil will have them discovering the truth while chasing their dreams. My take on the combined worlds of Fate and DxD with characters from other franchises if they can be adapted to it. Harem.

Emiya Shirou pensó que había muerto después de haber matado a la muñeca de Sakura. Chloe von Einzbern pensó que una vez que Darius destruyera su carta desaparecería para siempre. El Counter Guardian EMIYA pensó que volvería con Alaya ahora que se despidió de Rin. Entonces solo tienen una pequeña, pequeñita preguntita. ¡¿Por qué carajos ahora son hermanos en un mundo de dioses!

A what-if story showing the inner workings of IF's guild, featuring characters from the Fate/stay night series! (Rated M for blood and adult themes.)

The Kaleidoscope: the essence of Second Magic, containing within it countless parallel worlds. A place where all possible realities exist, where fantasy meets reality. Worlds of Holy Grails, of Masters and Servants...and Riders.

Between the time when the oceans drank Atlantis, and the rise of the sons of Ayas, there was an age undreamed of. Hither came Shirou, red-haired, golden-brown eyed, sword in body and soul. A saviour, a slayer and a lover of witches most beautiful and dangerous. It is I, his chronicler who alone can tell you of his saga. Let me tell you of the days of High Adventure.

It is well-known throughout the Kaleidoscope that every version of Shirou Emiya in existence is lucky with women. Every version, that is, apart from Counter Guardian EMIYA. His history there is atrocious - but even he didn't expect one of his relationships to end the Age of Man. E Rank Luck really is a bitch, isn't it?

Ainz in the FGO! Will it be a challenge for him? (Spoiler: No). No roflstomp, no hate, no bashing. Just the pure Ainz magnificence in play. It's actually a FGO-fic, but since there are plenty of FGO-fics in the Fate-general category - it was made like this.

Ishtar and Ereshkigal want to save Shirou and Hakuno. For this, they are ready to break a taboo. To avoid punishment, the two goddesses just flee to another world where the Age of God continues. The plan was perfect, what could go wrong? Except gods are prey in this new world...

Shirou Emiya finds himself in another world after sacrificing himself to save Fujimaru, in a world of gods and monsters. On the verge of death, he saves a young girl, before succumbing to his wounds, thankfully, the young girl just may end up being Shirou's salvation, in more ways than one.

You all know the events that lead up to Sora's disappearance from his and his intense battle with Yozora. But what if instead of ending up in the city Quadratum, he ended up in the fabled Clock Tower, meeting the infamous Wizard Marshal. Guided by him, Sora ends up in a world where humanity is on the brink of destruction and must save it with Chaldea's Final Master

Alternative version. Yes, this is a story about an alternate version of Shirou Emiya who reincarnated into an alternate version of the world of Danmachi. This is a story about a young man who goes on an adventure in the depths of a dungeon full of mystery.
