There’s only one rule in this Holy Grail War: out of the 1.5 billion people in this world, the last one standing will win the Grail.

—This is the story of seven kings from different eras descending upon this world, bringing with them their kingdoms, subjects, armies—even their lands. They all converge on Jerusalem to conquer it, fighting for their respective ideals and nations, in a battle to seize the ultimate Holy Grail. In short, it’s the Kings’ Holy Grail War!

The Conquering King, the Heroic King, the Omnipotent King, the Sun King, the Thorn King, Charlemagne, the Holy Roman Emperor, the King of Magic…

Faced with such terrifyingly powerful opponents, Suya—who transmigrated into this world, was forcibly dragged into the war for the survival of Britain, and became the rightful King of the entire land—realizes:

No matter the reason—whether it’s to stay alive, to protect a fake crown, or for the sake of the false Knights of the Round Table who follow him—right now…

“I must draw my sword immediately!”

Morpheus, who had traveled to the world of "A Certain Magical Index," was still sorting out the mess left by an evil magic society when he was caught in a space-time turbulence and transported to the world of Type-Moon. He was reborn as a baby, adopted by the Macremis family, and Bazette's younger brother. As he prepared to fight the Fifth Holy Grail War, he discovered that this world was actually the FGO world, where the Fifth War had never existed. So, for the sake of world peace and to once again pursue the ultimate secrets of magic and become a demon god, Morpheus Fraga Macremis, a golden-type magician, embarked on a journey to save humanity.

"Servant Saber Akame, in response to our previous meeting, nice to meet again, Master."

"Archer Misaka Mikoto, eh, do we know each other? Hey, hey, hey! Master, your pick-up method is too old-fashioned."

"Servant Saber, I came here in response to the summons. Well, just call me Kirito."

"Servant Archer, my name is Tokisaki Kurumi. Ah, Koizumi-kun, we are also an accomplice who saved the world together. Why are you hiding from me like this?

This book is also known as "Type-Moon Pot King" and "Time is Saved"

In ancient mythology, there is a dark shadow that surrounds the world, looking up and waiting for the day to devour the gods.

It once deceived the hero king Gilgamesh to break with the gods and led to the return of the great disaster Tiamat;

it once collapsed the authority of Olympus and seduced the goddess of wisdom Athena to raise the banner of rebellion;

it once abducted the goddess of winter Skadi, humiliated Asgard, and set off the twilight of the Nordic gods;

it even personally promoted the war between Britain and the white dragon, and led Joan of Arc to fall.

Therefore, it has been given many extremely dark titles.

"[Shadow of Babylonian Terror], [Aegean Sea Disaster]!"

[Asgard Nightmare], [Seven-Headed, Ten-Horned World-Destroying Demon]!!" [Messiah's Enemy], [Original Sin of This World]!!!"

Obviously, we all did the bad things together, why am I the only one who suffers?

However, when a man named Toshiomi Toshiomi summoned him with a snake skin,

Lin Xian (Samael) looked at the magician's vigilant action of shielding his daughters behind him, and he understood... he would

definitely bear the blame!

"Because glory lies far away!"

On the Magic Eye Collection Train, the Rain Witch smiled with satisfaction as she watched El-Melloi II display the might of the king's army in front of Hephaestion.

"Broken down~"

In the world of Artificial Girl + Rozen Maiden, the fairy tale witch hugged the mercury lamp and hummed briskly with light steps.

"This is a friendly vampire."

In the world of Bloodthirsty Assault, looking at Nangong Nayue with a wary face, Elquet smiled and waved.

"Seven dragons, turn into my fingers!"

In the world of Problem Child, Draco (Beast Nero) rushed towards the high sun with a grin.

A simple life—legendary swordsman, Knight of the Round Table, Lord of Camelot, Davian Slyrik.

Morgan: If I can’t have it, no one can.

Artoria: When the road has reached its end, Davian… I will avenge you.

Mordred: If I can’t take Britain from your hands… then let it burn!

Davian: Tatakai! Ichimo tatakai! (Fight! Always fight!)

Kagerin, who traveled to Type-Moon, had a fantastic start with a 9.3 rating, but his fate was shattered when he encountered Kukulkan in Fuyuki City. "Is this still the Fifth War? We've already reached the Lostbelt." Fortunately, the cheat code arrived. [Travel to a certain era, and your actions will be settled based on your actions.] [Warm reminder: I don't have any talents.] "Without any talents, trying to build a good board just forces me to go the popular unofficial history route!" "Wait, I think I understand." [How did the spirited young Minamoto no Raikou become the shogunate's sole shogun?] [The millions of monsters led by Ibuki-douji and Shuten-douji were no match for you alone. You must have sold them out...] [The incarnation of Izanami walks the world, why does he have a special liking for you?] ... [King Arthur's secret as a woman is revealed.] [Morgan's confidence explodes, and Britain is divided.] [You prioritize the greater good and reconcile the sisters. [You saved Britain, but Morgan and Altria fell into civil strife because of your beauty and wisdom.] ...To prevent the world from being destroyed, to protect world peace, and for the greater good, Yinglin can only feed the demon with his body (don't worry about being tortured by a woman and turned into a ⭐⭐). "Don't be afraid, children, the male god is here."

Carl traveled through time and space and came to the capital of Camelot. He opened a small restaurant here and planned to live an honest life.

I don’t know if the people in this place like dark cuisine or don’t go out to eat. There are very few customers in his small restaurant. The only one who often comes is a young lady named Al and her companions.

"Do you think King Arthur really doesn’t understand people’s hearts?"

"Do you think King Arthur really deserves to be called the Chosen King?"

"Do you think Mordred can inherit the throne?"

Hearing that this young lady is so concerned about these messy things, Carl is helpless, but he still tells her about it because of the money she gave.

Finally one day, Altria, who used the alias Al, couldn’t help it.

"Boss, I’m going to show my cards. I am King Arthur!"

"What!? King Arthur can’t be a girl!"

An Zhiyu traveled to the Land of Shadows, training day after day, year after year, with his master Scathach. In the evenings, after martial arts training, he would receive instruction in magic from Morgan le Fay. Initially, he and Morgan le Fay got along well, and he formed a favorable impression of her.

Then, one day, Morgan le Fay suddenly said, "In a week, the King's Choice will begin. My sister Artoria will extract the Sword from the Stone and become king... I need your help with something."

"What?" An Zhiyu asked.

"Before her, extract the Sword from the Stone, and marry her."

"???"

"The curse has been activated. From today on, you must find a way to marry Artoria!"

This was a world where timelines intertwined. He had extracted the Sword from the Stone, resolved the conflict between Scathach and her sister, and aided Gilgamesh. An Zhiyu thought he would continue his adventures like this.

Until one day, he was summoned by the Holy Grail.

Looking at the group of old acquaintances in front of him, An Zhiyu waved his hands awkwardly: "Hello..."

Artoria smiled and raised the holy spear in her hand:

"Shine in the End of the World!
