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!”

My name is Shirou Emiya, and I've been away from Earth for who knows how many years. One winter, when I was seventeen, I woke up in a completely unfamiliar place, probably because I'd been sleeping in a warehouse. But with the help of a friendly wizard and the culprit who transported me to another world, I became a wizard myself. Now, I'm a chosen one of the Goddesses of Magic, with an average career of six hundred years, and I'm still seven or eight hundred years away from retirement. But one day, I found myself back in the mansion my father left me. —Humanity burned? Saving the world again, huh? It's a job I do all the time. My name is Shirou Emiya, and my life's dream is to be a righteous companion, to end the tears of the innocent. This book is also known as "Shirou Emiya, the Returning Max-Level Mage from D&D" and "The Protagonist's Dice Are So Powerful I Can't Continue This Book" (this book features the sole female protagonist, Altria Pendragon).

Lin En, seemingly an ordinary Chinese language teacher at Sobu High School, harbors a secret. He's the sole occupant of the "Ten Thousand Worlds Safe House"! His "classroom" connects the world's most elite "problematic beauties"! At the outset, the safe house "picks up" a young girl who's recently lost her sister and is filled with hatred. Faced with her murderous intent, Lin En gives her a single assignment: "Go back and face your anger!" As Shinobu Kocho unleashes bloodshed across the Demon Slayer world with this "assignment," Lin En uses his first reward, "Emotion Perception," to precisely tap into Yukino Yukinoshita's loneliness! → Homura Akemi: From "Desperate Girl of Reincarnation" to "Demon God Who Controls Time and Causation," rewriting fate and subverting the universe! → Misaka Mikoto: From "Sinful Princess of Electricity" to "Thunder Empress on the Path to Absolute Power," piercing the divine realm with lightning and reshaping the order of Academy City! Of course, there's also the occasional everyday pretty girl... This world is truly wonderful, but sometimes it's just too much...

Du Wei traveled to the world of Kamen Rider Saber and was chosen as the guardian by the Book

of Omniscience and Omnipotence! But the story has not yet begun.

Du Wei saw the mercury snake that repeats reincarnation.

"Can you bring me the unknown?"

Mercury, who seeks the unknown, grants the snake a favor.

Rebuilding the Saber Driver and the Domination Sword based on the eternal destruction opens a new chapter for the story!

Bawanxi: "Bring me more sorrow, dear~!" Morgan

: "It turns out that you are what I lack in my rule. In order to not fail again this time, I will make a law that has both ambition and you." Melusin:

"You are the star I look up to, and the meaning of my existence is to be used by you."

The world that he traveled to for the second time is the British Lostbelt of Type-Moon!

Du Wei is a Kamen Rider who carries the principle of eternal destruction.

Exercise the principle of hegemony and achieve the supreme position of God.

"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

[Day 1 of the time travel: Wearing Adi King's battle suit and dark red hair, is Emiya Shirou actually me?]

[Day 3: Confirmed, this isn't the UBW questline, no Red A experience packs, so I'll have to rely on myself to master Unlimited Bladework.]

[Day 20: Strengthened my magic proficiency and began practicing Projection. During this time, I met an alchemist who asked me where I got all these alchemical weapons made from recycled metal.]

What the hell is recycled metal?

[Day 90: Finally mastered my first Noble Phantasm, Projection. They exclaimed, "This is the Seven Kingdoms," an outstanding achievement in alchemy."]

Huh? I don't really understand you alchemists.

...

[Day xxx: Huh, I finally mastered Unlimited Bladework! Their expressions were fascinating, and they asked where the Nibelungen was.]

How come you don't even know about the inherent barrier? Isn't this... Type-Moon!?

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."

> "Rod, remember this: the prettier the woman, the better she is at lying."

"It's fine, Mom. That's exactly my type."

"???"

◇◇◇

After transmigrating into the Type-Moon universe, he became Beast VI — a Beast defined as the Revelation of the Power to Kill.

Rod once believed that as long as he avoided responsibility and indulged in wine and women, he could certainly escape the fate of the appearance of Human Evil.

But in the end, events spiraled far beyond his expectations.

One by one, the female heroic spirits around him were corrupted by him and turned into Alters...

I met the stupid golden-haired True Ancestor by chance, and I tried my best but couldn't defeat him.

It wasn't an accidental encounter;

it wasn't my best effort.

---------

"So, Mr. accomplice of the murderer, you have to take responsibility--"

the golden-haired True Ancestor said so.

In AD 2014, more than two thousand years after the birth of the first magician, the last princess of the True Ancestor met someone.

Xu Xiao found that he might not be a human. When he looked back, he had experienced many incredible adventures.

The crimson stains falling from the moon, the [Ancestor] that is incompatible with others, the mysterious war for the universal wishing machine, the [magic] that is beyond human understanding...

The immortal agent, the golden-haired True Ancestor, the princess of the origin, the fairy tale witch, the magician, etc., not only himself may...
