Our protagonist was reading a Fate x DxD fic when he suddenly woke up inside the body of King Arthur from Fate in an abandoned church. He has a System and can collect Servant Cards from around the world. At first he was overjoyed to be living his dream, but he quickly finds out that this world isn’t as kind as he thinks it is. As mythological figures clash, he tries to survive.

A warrior that would go out of his way to save others... perished with a smile in his face, as he witnessed first hand, that his legacy will be carried on, 1000 years from then. Watch as our Protagonist and his servant of Arthurian Origin, traverse the world, and defeat foes that would bring harm to those around them, and hopefully, fix some unsolved "family issues".

In a world in which humanity never parted ways with the Gods and became the dominant species, an unexpected variable enters to disrupt its delicate order. After regaining his memories as the nameless hero King of Fakers, Emiya Shirou will have to teach this world why humans cannot be underestimated, and show them all what means to be a real hero.

As Devils one of the many sins that are most recorded amongst them their lust is one of the strongest cravings among the species. In this set of short stories these are the various tales of what-ifs that occurred to our hero and heroines. (All Events are AU from the HOC series)

Honestly, I should have expected it. After all, my line of work would always be screwing with me when I don't need to. What I did not expect was getting myself into a world where Gods are alive and around, Angels and Demons are real, and the residents are really weird. I blame Zelretch for this. Rated T for the time being. (Yes, the title has been changed / Sporadic Updates)

Depois quê fez o trabalho de Zelretch e as tarefas de Gaia e Alaya, ele voltou para o seu mundo juntou com a sua filha adotada e as suas companheiras para o mundo dele. O mundo de DXD não está preparado para o cavaleiro dragão.

I was just your average teenage boy bonded to a holy spirit and then one day…I wasn't. Overnight, my world had changed and if I didn't learn to swim, I was going to start sinking fast. Well, I've always been handy with swords. Hopefully, they'll be enough for whatever the Moonlit World has to throw at me. ShirouxHarem, IsseixHarem, Rated M for DxD

To be updated :). Rated M for language and violence.

Diversión y llanto, ambos juntos, una reía y el otro callaba. Una opera que ambos interpretaban ante un público inexistente, una vida que no se vivía y una vida que quería ser vivida. ¿Finalizar todo por una oportunidad? Un contrato y una promesa, una maldición como una bendición, dando paso a aquella risa unísona que resonó para el miedo del mundo. Emiya&ProtoMerlín.

While exploring a rogue Singularity everything goes wrong when Ritsuka falls prey to the schemes of a Foreigner Servant who uses a Holy Grail to transform the hapless Magus into one of the Outer God, Shub-Niggurath's, Dark Young. Now cast into a strange new world of angels and devils can the wayward Master find her way back to Chaldea?

With the discovery of a new world on Chaldea's part, one unlike anything they've seen before, an exploration team is set up to uncover the mystery of this world of Demons and Humans alike.

Un encuentro, una mirada y una palabra. ¿Quién era aquel que se paraba entre los caídos? Una mirada con pena y un ángel que obedece, la curiosidad no es algo con lo que se nazca, el pecado no es algo lo cual se obedezca. Solo existen caminos fragmentados que conectan a un rumbo sin destino fijo. Un destino que se tambalea como las decisiones de muchos.

After his sacrifice to destroy the Grail, Shirou is now reborn as Hyoudou Shirou by the power of an Old God. Rated M because it's Highschool DXD and things might become spicy later! FemIssei as Sei!

algunas veces el destino hace un giro de eventos inesperados, una persona puede cambiar todo

He knew he would be going to hell, despite the fact he saved the whole world from the 'Promised Time'. He didn't expect this particular 'hell', neither did he expect to find himself as a fucking dragon nor did he expect to be dropped in the middle of civil war between devils, at least Mercury-chan and Fou-kun's with him. "Always, Master." "Fou Kyu! "...ShirouxHarem

Shirou has lost everything in the fifth holy grail war and mysteriously got himself teleported to the world of Draconic Deuse after he got swallowed the greater grail's explosion. In this new world where the Age of Gods hasn't come to an end. His life begins anew.

The man once named "EMIYA" realises something in the ruins of Einzbern Castle. No matter the people they meet, the place they're born, or the shape of their body, Emiya Shirou will always arrive at the same answer, the same conclusion; at Unlimited Blade Works. It is a female Shirou who proves the worth of Kiritsugu's ideals to Archer, and is left to wander the Moonlit World.

The right man in the wrong place can make all the difference in the world. Where truth is stranger than fiction, mythology blends with reality, and supernatural factions lie in wait for the next full-scale conflict, what difference could one human at a high school in Japan make? "Heh, the answer depends on who you ask." (Slight AU) (Elements from other series included) (Now on AO3)

E-ranked luck is a funny thing. Dragged alongside Gilgamesh into the hole left by the grail, a desperate plea sends Shiro tumbling into a world vastly older, and much more active than his own.

Un personaje de Fate logra viajar al mundo de DxD, teniendo que enfrentar aventuras que realmente no pidió debido a que nunca fue un protagonista.

He was a boy and she was a girl. One is three meters tall, the other is shorter than usual for her age. Still, they're pretty close to each other despite it.

Tatsuka Rikka. That is my name. Some time ago, I landed in an alternate DxD world and found out I have a Mystic Eyes that lets me analyze every spell that I sees and a replenishable Command Spell that allows me to transform into Servants, to which they're the ones in control of. Oh, did I mention the transformations are based on a num gen? (No harem or pairing for MC) [Also on Ao3]

Sequel to "It's Always Sunny In Trifas", the Fate/Apocrypha Dual SI featuring myself and Lord Trent Blackmore. Read that first! That said, this will be a Highschool DxD/Fate crossover, with the bulk of the crossover being DxD. Be ready for big dumb shonen shit and big dumb anime tiddy, because that's this setting in a shellnut.

After his victory in the Holy Grail War, Yuto Emiya was gifted a second chance at life. Now, he is given the chance to make up for his decisions. Even in Victory, all he can see is defeat. (I'm bad at descriptions, but I hope you enjoy)

Jamais Rituska Fujimura n'aurait imaginé porter la responsabilité de toute l'Histoire Humaine sur ses épaules. Mais à la fin, malgré que sa mission ait été remplie, une défaite amère l'a accueilli. Ainsi, dans un autre monde, un autre jeune homme un parmi tant d'autres, reçoit son héritage. Comment évoluera-t-il, alors qu'autour de lui, l'Âge des Dieux ne s'est jamais terminé ?
