As Sieg flew to the Reverse World in order to bring the Greater Grail away from human hands he did not expect to arrive in a world constantly at war between devils, angels and fallen angels. It seems like he will have to face a lot of trouble protecting the wish granting device while waiting for Jeanne's arrival.

There were the original Demon Lords that fought in the Great War, and then their immedeate descendants. There are the Four Demon Lords that usurped the former from their positions after a painful Civil War, and the heirs of the deposed clans who seek their lost glory. And finally, there is the Tetrarchy, who would play their hand even beyond the Underworld.

The Holy Grail, an artifact of unimaginable power. It has been said to grant any wish. But we all know what the Holy Grail war is. So in a far different world from its own, let us join a normal high school girl who goes by the name of Isaiviel. Someone who was not only unwillingly dragged into a not so familiar War. But also the world of the Supernatural.

On the day before he was to die, Issei Hyoudou received a deck of cards, albeit very bizarre ones. The next day, just before Issei is about to be to killed by Raynare, an unknown power awakens within. Reviving lost souls? Cute monster girls? Angels and demons? Not quite what he pictured his life when dealing with insanely hot women. Non-SG Issei/Heaven's Feel Issei

He was sent by the Moon Cell to prevent the destruction of the entire human race of a certain world despite not being part of the Human Order himself. He will learn to live alongside with its denizens, human or not, all the while upholding his mission that was given to him as a Servant. Possible Harem. [WARNING: SHORT CHAPTERS].

Rewrite/Another Take of Red Dragon of Apocrypha. Hyoudou Naomi was chosen as the Seventh Master of the Red Fraction for the upcoming Holy Grail War. She already got her catalyst, a comrade, and set to go. The problem? She had two very much unexpected (and semi-unwanted) extra passenger.

The balance of power shifts as a oblivious faker simply tries to help others and go home.

It's a dark and stormy night and the team can't go anywhere, however Ace Gremory younger brother of Rias Gremory is down and lost in thought. He tells the team his story three years before the events of the anime and how he was forced to fight for his life until Rias saved him.

After winning the Grail war, Link asks the grail to be reborn in a different world without the war where he and others who'd fought beside him could live in a more peaceful way but have the powers of those they'd lost. What he got was definitely not what he was expecting.

Ishikawa never expected any of this to happen, that is until one day something happened in the park which escalated a non-stop chain of events which always seemed to involve her in them. Fem!Issei, !SlightAU.

After Dragon Knight Luna fell into his arms, Hyoudou Issei was forced into a world that he never knew existed. However, just because he lacked knowledge of it doesn't mean that he wasn't once apart of it. Find Alaya was going to be difficult, but discovering his true identity was even more challenging. The Counter-Guardian, Satan, walked among Man once again. [Issei/Multi] [AU]

After being defeated by that Faker and being sucked into the Holy Grail, the Grail decides to add insult to injury and reincarnates him into some world with the Age of the Gods still going. As a girl! No matter, he was the King of Heroes, the One True King of the World. This world will learn that lesson just like his last one.

War approaches! Kokabiel has stolen the Holy Weapons of Charlemagne's Paladins. The unsteady peace threatened. Tensions between factions shimmering, on the verge of exploding. Ally turns on ally, friend becomes foe. Suspicious eyes gazing at every dark corner for what could lie within. Exorcist Griselda is given the task that may turn the tide for the better or worse...

Contrary to what most believe, Zelretch DOES actually try to help out the world. Most of the time. But he can only be in so many places at once and there's no shortage of unpleasant things out there that can hop between worlds as easily as he can. Thus, he turns to his cosmic janitor friend Horatius and his Heroic Spirits to lend a helping hand. Until a joke goes awry, that is...

High school student? Check. Heir to a human organization that deals with the Supernatural: Also check. Young Castiel Emiya, son of Shirou Emiya, lives what some might consider a double life. Involved with the supernatural since birth, how would he affect the world of DxD? Let's find out! (DISCONTINUED, Rewrite up)

My name is Max, with the help of a ritual I find by accident I summoned 14 special helpers in my objective of survival, but why does it seem like the world REALLY wants me to die? Seriously, it is like there is the end of times coming or something. Well, I am the heir of Mammon, the Demon of Greed, so I will end up winning in the end, no matter what.

Following his death and resurrection, Issei Hyoudou had entered a world of angels, devils, and everything in between. However, through the intervention of a single drinking cup, things turned out rather differently. The Welsh Dragon Emperor would come face to face with a Holy Sword Wielder sooner than expected. (There will be some non-FSN elements beyond just the servants used.)

Ayala decides to Give Shiro a "gift" for this mission. This story is my first true fanfic so feel free to give creative advice.
