As the apocalypse draws ever closer, a new power will be born. With the strength of over one hundred heroes, a failure of a master must overcome the world's strongest; the future of humanity lies in the hands of Kamen rider Diend, Gudako Fujimaru. The Grand Order has begun, a new history is born with one key word: "Henshin!"

In a world parallel to the normal realm of Gaim, Helheim has overrun Zawame City. This causes a divergence in the timeline, creating a new Lostbelt for the crew of Chaldea to deal with. With Kazuraba Kouta nowhere to be found, can Ritsuka and his assortment of servants deal with this new threat?

At the edge of despair, he grasps onto a spark of hope. When his old life ends, a new one opens its door. A new purpose drives him to become a beacon of final hope for those drowning in despair. Only now, he has been dragged into a war with seven others. Can he stop the enemy from taking the Grail or will all fall into despair? He is the Yubiwa Mahoutshukai...Kamen Rider Wizard.

"IWAE! He is the Master of countless Servants. The heir to the power of all Kamen Riders, and the rightful ruler of time and space! He is Kamen Rider ZI-O! Watch as he takes his first step towards king-hood!" "...but I don't want to be a king!" [Currently Revamping]

Hakuno Kishinami had made a wish. A wish to survive and live. The Moon Cell, in the process of deleting her, had ultimately chosen to grant her wish, as was her right as the victor of the Holy Grail War. Upon awakening, Hakuno finds herself in a peaceful world, and under the care of a kind man and his nephew. But trouble is brewing. And a new battle awaits on the horizon.

Sougo thought that when he defeated Swartz, the timeline is safe. But when Tsukasa warned him about another threat in the timeline. He and the Kamen Riders must team up with an Organization called Chaldea to fix seven Singularities.

Shirou Emiya thought that he lived in a normal world. Being stabbed and killed by a sludge wolf monster, only to be revived and turned into an armored superhero made him reevaluate that idea. At least now he can actually become a Hero of Justice. I mean it's not like he has to worry about his life anymore. After all, he's already a Ghost.

High school harem antics by day, saving Fuyuki by night (and sometimes day). Becoming a Kaleid Rider made Shirou Emiya's life interesting, that"s for sure. (Illyaverse!Shirou)

In Fuyuki City Japan, there are 2 wars to be fought. The Holy Grail War fought with Servants or Heroic Spirits and the War for Ventara fought with Kamen Riders and Mirror Monsters that emerge from them.

Hakuno, a high school student, must defend his school and his city while aiming to get into conflict with as few Riders as possible. With his companions; Rin, Kamen Rider Delta, Rani, Kamen Rider Ixa, Sakura, Kamen Rider Marika, and Shinji, Kamen Rider Snipe, they must fight to survive and to keep as many civilians as possible safe from the battles to come.

Humanity as we know it is gone - love and peace are things of the past. The self-proclaimed genius physicist answers the call of a desperate Ritsuka. (One-shot?)

The world has ended. The king of mages stood atop it's ruins, and ten people granted with the gift of Science stood against him. This is an accumulation of their paperwork. Because no matter when or where it is someone has to do it, but hey at least he's getting paid for this.

23 years after a Unlimited Blade Works route ended with Tohsaka's victory, another Grail War is taking place in the "adorably" named Seihai City. Why is another Grail War occurring? Who are the Masters participating? And why are...they the Servants being summoned?

Obtaining heaven. Chaldea battles an unknown force to reclaim humanities' future. However, neither side will be the ones to chose the fate of humanity. It shall determined by one who fate calls to. To dye the world in his image. A young man, called by fate, shall fight to determine humanities' fate. The ultimate battle has begun: Grand Order!

It's a trailer for the F/GO x KR Gaim story I'm going to make.

The Holy Grail War has begun again. One amnesic Master has lost the life that he once had and now struggles to protect what is left of the life that he has come to accept, but now faces the possibility of losing it all. With his Servants by his side he will protect what is left as he tries to figure out the secrets of his past as he unlocks the power of the forgotten hero... Agito.

After surviving the Fuyuki fire disaster, Shirou was taken by The Society of Shadows who transformed him into a superhuman through forbidden science and dark sorcery. Ten years later, he escaped the organization and returned to Fuyuki City, attempting to trace his true identity he had forgotten, just in time for the fifth Holy Grail War to be conducted in said city.

He remembered. He remembered it all. The power he once wielded, the war he went through, the death's he caused, the girl he protected, the child he saved, the monster that killed him, his last stand with his friend and his dying wish to him. Now with his power restored the legend of the rider war shall return to the battle field. (Chapter 2: Poll results.)

Following the events of the recent Holy Grail war, Taiki Kudo is about to resume his normal life and help his friends, but FATE has other plans when he is taken to another route where the Holy Grail war exists, and that even Armored Riders and Yggdrasil are involved in addition to the Masters and Servants, and now he is forced to fight again to survive. Feat. KAMEN RIDER GAIM.

In a war where the good must fight each other only the one who fights hardest will survive! Every Servant is a Kamen Rider, summoned from the throne to heed the call of the Holy Grail. Some fight for themselves, some fight for others and some don't need a reason at all. The Holy Grail is filled with many heroes, many of them are Riders.

Basically these are random Kamen Rider Idea's I have but are not likely to have anything done about them so they are all up for adoption next is Gaim Anime War
