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!”

【Fate fanfiction, Charlemagne as male lead, includes original characters and settings—if that’s not your thing, please avoid reading】

The author is extremely amateur, the plot isn’t particularly tight, and the romance is kind of awkward.

If this causes you a bad reading experience, I can only apologize—

I’m truly sorry! bows repeatedly

———Now for the serious synopsis————

As an ordinary person, Fujika Tsukizuki suddenly found a Command Seal appearing on the back of her hand, marking her as a Master chosen by the Holy Grail.

With a “might as well try” attitude, she half-casually and half-seriously aimed to summon her all-time favorite Servant—

and somehow, she actually succeeded.

“Wait… could I actually be a genius at magecraft?”

“But hold on… who in the world summons a Servant using merchandise?!”

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 Lancer Remlia Scarlet... Queen of the Night, reigns here. From now on, I will be your master, servant, are you type B blood?"

"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.

Since you are here, come in and take a look

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!)

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!"
