Simple actions and choices from the past have the power to alter the future drastically. Shirou found himself discovering a small trinket of no value to many.

A twisted fate which coiled itself into another reality, one where Shirou would embark to find his answer.

Chaldea, the bastion of humanity's survival. After more than their fair share of world ending singularities. Peace times have finally come, only... not everyone is so keen on the boredom that follows. Three resident heroic gentlemen take it upon themselves to spice things up. How, with a react series starring the resident servants. So come on and enjoy... Chaldea Reacts!

After UBW good ending - Emiya Shirou realizes that he needs to get better...get stronger to better face his future challenges and not become a burden to others who chose to believe in him.

In the middle of a possible Stray hunt, Rias Gremory accidentally ended up with three marks on her hand due to activating an unknown spell. After researching them, she discovered their use of calling forth a possible familiar. But what came from the summoning was a familiar that not even a Devil could have ever imagined.

All it took was a single oversight, a single change in decision. Now the last of the Nanayas has fled Misaki after the death of his family and the boy blessed with avalon has been adopted instead. Shirou Tohno is now returning home after the death of his father, only to get dragged into the war being waged in the shadows of the city. His presence alters the course of history.

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.

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.

The Bible God didn't plan ahead for a development such as this. The last fight between the previous hosts of both heavenly dragons had drastic effects on not only Ddraig but his current host as well. Now that he was free from his prison, nothing would ever be the same. This is just the beginning of a new story for Ddraig and Issei.

A certain technician is invited as a member of Chaldea's staff until a chance discovery changes everything and lands him into an ordeal with the fate of Humanity itself at risk.

Issei Hyoudou is the Sekiryutei. Not many people knew how powerful he is, or what he's done. And he's perfectly fine with that. He's done with people. All he wants to do is sit back, relax, and watch porn without being bothered by school or homework or devils or fallen angels or annoying conspiracies and why the hell won't they just leave him alone already! Perv OP Issei Harem.

The three summoned their Servants for their Holy Grail War. Their Servants aided them till the very ends of their lives and forever changed the course of their war. However, the smallest and most insignificant details can lead to the most consequential and strangest changes. After all, there are other Servants similar to those three...

Shirou lands outside of an abbey, heavily injured and on deaths door. Luckily a holy maiden was nearby. After recovering, the pair end up saving a girl with cat ears from devils. It appears, that no matter where he is, Shirou is destined to get dragged into matters beyond his control. (Partial Rewrite to streamline and clean up the story.

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?

It was a simple proposal. Zelretch offered Shirou a role in Rin's education, and he accepted. What he didn't account for was the new job he was forced to take up. Now as a host for the Interspecies Homestay Program, Shirou must adapt and survive against an enemy he has never faced before. Monster girls. UBW!Shirou

What would happen when Ritsuka summons Emiya Shirou in Chaldea? The result: chaos. Crack fic.

Issei Hyoudou is a lot of things, his most notable trait being the fact that he's just about friendly with everyone; even otherworldly beings! So one can only imagine what his daily life is when he's frequently visited by mind-boggling entities, monsters capable of tearing the world asunder, and even gods. How does he keep doing that? (Crossover)

"With swords that aren't yours, with skills that aren't yours, for dreams that aren't yours. Your entire existence is a lie!" - "Then I'll show you that even fake dreams can become reality." A different choice, a different path, a different FATE. Shirou/Multi

But this time, he ended up summoning a certain nameless hero. Now, the King of Heroes and the King of Fakers will have to put aside their differences to defeat the Gods and save humanity.

First fanfic, sorry if some stuff is weird, or if the story itself is bad. Anyways, it's a react fic about Archer Emiya's backstory. Standard "characters in theater are watching the anime/story", you know? Pls tell me if it's good or not.

Shirou Emiya's life is cut short, but fate isn't done with him yet, and he meets the Goddess Aqua, who sends him to another world. Armed only with his razor wits, magecraft, and sheer will, Shirou must do the impossible and defeat the Devil King. Ft Abridged Shirou.

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!

Author Omakes related to the Swords and Sorcery series. Mostly joke chapters and "what-if" scenarios. With magic at hand, anything is possible. Well, maybe not "anything", but lots of things. Lots of wacky, weird, crazy things. WARNING: may contain spoilers or implied spoilers for the main story.

Book 3 of the Swords and Sorcery series. Shirou and Iris continue on to their third year at Hogwarts.

What can a Retired God, a Treacherous Knight and a Boastful King do to save the planet? [AU]

Honestly, Alaya wanted to screw another pair and cause more problems for a certain Counter Guardian. Enter— one Arthur Pendragon and Merlin!

Issei supposedly dies in the altered dimension after fighting Shalba Beelzebub, however, he is reborn and is stronger than ever? How does this event work out for him? Only time will tell I do not own any part of High school DXD. All the copyrights belong to the original Authors

A new Singularity has been detected, where it is possible to watch fragments of real or fictional events as long as a catalyst is used. Cú Chulainn gets excited, uses himself to watch the war where he and the others 6 servants fought (UBW route), but when the fragment starts they quickly realize that maybe is not the right route...

Miki, and Gorou Hyoudou have already lost 2 children due to miscarriages, but on the third child they were desperate to make this child survive. They did everything, even to pray to some god out there to deliver this child safely. Unknown to them a certain Dragon God was going to fulfill their Dream.

Kobeni Higashiyama signed up with Public Safety as a devil hunter to make money for her family and older brother, but she wasn't expecting it to be this chaotic, especially when she met Denji - a fellow rookie. (A slow-burn romance with gradual divergence and an excuse for Denji x Kobeni shipping)

Basically Miyuverse! Shirou died and was summoned by Aqua to be reincarnated into her world. Shirou got cheats, and go Isekai in the hope to kill Demon King and reunite with Miyu. Warning! I might drop this at any time without warning, I'm only writing this as a hobby. Also I'm terrible writer, better look for other works.

Counter Guardian EMIYA had no wish for the grail, he did however have a single desire. Kill his foolish younger self. He finally finds himself summoned in Fuyuki. Only there's one small problem. This isn't his Fuyuki and what's with these 'Magical Girls?

Shirou suffered from the Grail's fire greatly, but was saved by Irisviel instead of Kiritsugu, who escaped clutches of Grail. With her help and guidance, Shirou will discover his past and open a path forward for himself, as heir of Muramasa line, holding it's greatest treasures and secrets.

Due to some circumstances, Issei Hyoudou has to leave his peerage. Many years later, Rias's new peerage seemed to have a new mission in front of them. What will happen to them? Have they recovered? Does Issei come back? Only time will tell. I do not own known High School Dxd.

Rin might have convinced him to take the gig, but Shirou had a funny feeling that this wasn't what she had in mind at all. If being a master of Chaldea was dangerous before, then now it was an outright suicide mission. Investigating all of these singularities on his own won't be very fun.

Fate Grand Order based, Shiro joins Chaldea with everyone's favourite Saber. First chapter is a mess, but please bare with me as this is my first Fate Fic.

Book 2 of the Swords and Sorcery series. Shirou and Iris continue on to their second year at Hogwarts with new friends and potential enemies showing that perhaps Shirou is not as far from home as he thinks.

After getting tired with RWBY Cinema Action, an entity ditches them for a quick break for a fresh cast of characters (victims). The Fujimaru Twins, Mash, Da Vinci, Mordred, Billy, Illya, and so on are now confined in the same theater. Forced to watch the other realms of their heroics , bravery, or plain embarrassments. Maybe even see realms beyond them. Hope they enjoy the view.

An accident with the Second Magic sends Shirou to another dimension. Trapped in a different world and a younger body, how will he manage to get back home? Perhaps the Hogwarts library has an "Inter-dimensional Travel" section.

This New Singularity...it hurts...every time I think about it I can only think about how ashamed she would be. It's time to end this, once and for all. (Oneshot. Based off the comic with the same name. WARNING MILD SPOILERS FOR THE CAMELOT SINGULARITY OF FGO!)

Issei was celebrating at a festival when a certain stall called the 'Throne of Heroes' caught his attention.
