One-shot idea for Supernatural x Fate based on season 5 episode 8. Exploring the possibility of an alternate reality.

Sam and Dean go to investigate strange happenings in Fuyuki, only to find that there is much more than just some witches or demons.

This is a crossover idea that I thought I would share to anyone who would like to write this story.

SN, Percy Jackson and Nasuverse crossover. The Mage Association is after a 10 year old Sam Winchester knowing about the demon blood in his veins, and they have hired the Magus Killer Kiritsugu Emiya to bring him to them. Dean, John, and Bobby refuse to let Him or those Monsters have him. Even if they die trying. MagusWinchesters! FemCas (no slash) future Destiel. Massively AU

A Fallen Angel, A Dark Magi, 8 Servants and Masters, One Holy Grail. Valerie is a fallen angel who becomes bored with the life of an angel. She wants adventure. To achieve this, she one day goes on an adventure to Egypt in the 15th century with her younger brother, Castiel. But then.. a dark Magi appears and tells her about a war that could give her what she's always wanted.

The 5th Holy Grail war has ended long ago and the remaining masters are living their lives peacefully. But an unexpected event is going to bring tragedy to their doorstep once again. A new Holy Grail War has begun without anyone noticing, new servants and masters are brought forth to fight in this war while old masters join the fight in order to discover what is going on.

Sam, desperate to either bring Dean back or save him from the pit, finds an unusual ritual. Except no one told him this ritual wasn't for normal people like himself. Oops. Now he's an outside observer to an ancient blood tournament that won't hesitate to kill him...with an unusual spirit from ancient times as Enkidu the only thing keeping him alive.

It's been nearly two years since the apocalypse that wasn't. Dean had more or less accepted that his hunter days were over… Until Bobby calls, with a case. Maybe one last job would help him settle for good… Wait, why's this witch using such a weird summoning circle? And what the hell is this mark on his hand?

Based off of the ideas of The Infamous Man and many other is a new Super crossover. The Holy Grail War has started in Fuyuki but this time the Kings of Hunters, Sam and Dean Winchester, have been summoned.
