Shirou died protecting women and children in a war zone. He didn't know what to do when he woke up in a new world with a new family. He had been a hero once already. Perhaps he'd take it slow and protect his new sisters. Whatever the case, Remnant now has two heroes it can count on, both are Roses, but will the two of them be enough to succeed where so many others failed?

The Fourth Holy Grail has come, and Tohsaka Tokiomi was more than ready. With allies and skill by his side, Tokiomi was certain victory was at hand. But fate has changed when instead of the King of Heroes, Tokiomi and the other Masters attain different spirits all together. All starting with a Maiden with Eyes of Blue. Now begins the Fourth Holy Grail War. It's time to duel!

Waking up and discovering your now the Gamer is pretty awesome. Discovering your system is based off Fate? even better. Having to deal with Types, Cosmic Horrors, and Teenage Drama? not so Much.

For ever path traveled in one reality, another one is taken. In one version of the world, Loki's invasion failed and his allies fell. But in another, the invasion still failed but Loki's Servant attempted to spite the Avengers and as a result, two worlds have become one. How will our heroes fare in this new world of bloody evolution.

A Goblet of Flames bathed Gold in a relic of miracles. Seven Masters who shall battle for the greatest of magics. Seven Servants who shall fight in the name of the master's for this ancient relic.

Sent to another world with the love of your life, and your sister might seem like a dream come true for most people. But for this sword, it's just a new journey in his life that he knows will be filled with many problems.

Reincarnation was not exactly what he expected after death. Despite this, Accelerator exploits it as a second chance to start over. But fate is unpredictable. Will he fall back into darkness? Or will he be able to walk the path of light?

When these two meet, the world will never be the same. AU beginning with the summer before 3rd year. Timeline has been moved forward 10 years to better fit with Fate/Stay Night.

A powerful anomaly breaks the boundaries between two completely different realities, heroes old and new are brought to a world where science and magic clash starting with the meeting of an unlucky boy and a foxy caster, how will they fair in the coming insanity(no longer including Poltergeist Arc)

After dying in her fight with Darius, Chloe von Einzbern (Kuro) is reborn in the world of DxD as the sister of Issei Hyoudo. What is her role in this new world, why did Zelretch Schweinorg send her to this world, and how many girls will she kiss!

After fighting off Angelica and saving Miyu, Shirou was transported along with her to a new world where they could be happy. Three years later, a gate to a different world's Japan would open leading into their new world. Can Shirou help the princess achieve a happy ending for the Empire? Or will Shirou be the villain for those he loves once again? Alex Kellar contest entry.

Shirou was aware that as a magus he shouldn't be surprised when something strange happened to him. But even then, becoming an isekai protagonist seemed a bit out there. At least he'd be able to indulge in his heroic instincts here. What could possibly go wrong? (Multiple FF games involved, not just XII)

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.

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.

He was an anomaly not meant to be in this world. Using his newfound power he received in this world he seeks further strength to live his peaceful life. But fate is irrational and he is dragged into things that he doesn't want any part in. [Self-Insert, Human MC, and Xover] This is my first time writing a story so please bear with me. Thanks!

Out of all the heroic spirits in Chaldea, Hans Christian Anderson would be the least eager to do anything hero related. Now, the reincarnated children's book author must use his fairytales to take on a world filled to the brim with more competent heroes and villians. At least he could still roast people to his heart's content. But just where is Kiara...

With the last of the dragons dead, there was nothing that should stand in the way of the lions' rule. Wolves and deer were nothing to their roar. Too bad that that night many years ago a certain archer was born between blood and fire in the tower of joy. For the Counter Guardian Emiya this was just a holiday, compared to the war of the grail the game of thrones was almost boring.

When I killed myself, I didn't expect to wake up, alive again in a young body that's objectively superior than my old one in almost every way. I certainly didn't expect to wake up in the convoluted mess that was Nasuverse with the nerfed, but still legendary and well coveted Game... Wait, was that Gilgamesh!

Multi-crossover mishaps.
