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).

After being blown away by a dump truck, Qian Yuan arrives at FGO's seventh singularity, the Absolute Demonic Front. What should he do if the world is about to end? Fortunately, his soul was replicated and scattered across the universe. Mei from Honkai Impact 3rd, Lei Yingying from Genshin Impact, Rin Tohsaka from Warcraft V, Shoko Toyokawa from MYGO, Ai Haibara from Detective Conan, W from Arknights, Illya from Makai, Athena from Godslayer... Qian Yuan can share power with his alternate selves and travel through the worlds, but why are all my other selves girls? My wife is actually me.

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...

Traveling through a parallel world, Luo Han became the boss of Mihoyo, a company on the verge of bankruptcy.

At this moment, he accidentally awakened the time-travel system, which allowed him to invite game characters from the original world to visit him.

He first tried to invite Nashida to Blue Star, and from then on he came up with the idea of making "Genshin Impact".

Let Nashida shoot the character PV "Happy Birthday" first, and make all the players on the Internet cry!

"Genshin Impact" has unsurprisingly become a hit on the entire Internet. At the same time, as more and more Genshin Impact characters have traveled through time and space, the company's painting style has gradually become strange.

"Lei Dianying: How dare you say I can't cook? Look, I'm going to chop this rice fool into pieces with my Wuxiang knife!"

"Kamisato Ayaka: I want to protest! Why do people laugh at me and call me 'Da Jia Gui Xiu'?"

“Ganyu: Stop talking about my dark history as a child! If you do, I’ll let you guys have a taste of how powerful Teyvat RPG is!”

"Hutao: The Blue Star branch of Wangshengtang officially opens today! Grand opening promotion, buy one get one free!"

"Dolly: Dolly's magical shop has everything. Don't miss it if you pass by!"

At the beginning, I encountered a star train that was as powerful as a monster that I couldn't defeat. I was reborn as a star core spirit and I must take everything back in this life.

But why is it not the sky but the stars? Well, there is always a trade-off. It is not impossible to become a star.

What does this mean? This is Fuyuki City.

Okay, okay, so this is how it’s connected.

Having traveled through time and space, I've gained the ultimate Heroic Spirit Avatar Legion System. The future of sweeping the world with an endless army of clones is just around the corner!

But... why are there only female Heroic Spirits?

...

"Can you tell me how you managed to find so many loyal and beautiful wives?" Fujimaru Ritsuka asked, stunned.

"It's mainly because... we're all connected."

Surrounded by beautiful women, Bree looked away awkwardly.

(Note to those in the audience: The male protagonist can transform into various female Heroic Spirits and use Heroic Spirits as clones.)

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.

Why is loving a single girl considered "pure love"...

But loving a married woman isn’t?

Is pure love really that limited and restrictive?

My love for these wives is genuine, beautiful, and untainted!

Their husbands? They’re the only obstacles standing in the way of my true love!

Besides...

There are tens of thousands of guys chasing after single girls,

But chasing a married woman? There’s only one man to beat!

I’m just too weak to fight the whole world—so I’ll choose to face only one rival at a time~~

Zhong Xuan transmigrated to the world of Type-Moon in the year 1994.

There, he awakened the "Cao Cao System" — the more famous characters he cucks, the stronger he becomes!

Thus, his performance began...

“Madam, you wouldn't want to...”

And in no time at all—

Tokiomi Tohsaka, Kiritsugu Emiya, Kayneth, and other legendary men…

Suddenly found a vast green meadow sprouting above their heads.
