The librarian, who was the champion of the World Swordsmanship Championship, traveled to the world of Demon Slayer during the Warring States Period, awakened the Great Swordsman System, and became a disciple of the Jigoku brothers.

From then on, he created various legends of his own in this world!

Muzan Kibutsuji: Facing Yoriichi, I can still escape, facing the librarian, I have no choice but to die! Yoriichi Tsugikuni: Your strength has surpassed mine! Demon Slayer Corps: The librarian is the most powerful man!

My name is Yamabuki Huajin.

I’m done pretending—time to come clean. I’m a transmigrator, and yes, I have a system.

My ability? Every day I wake up randomly in someone else’s bed and transform into a different anime character.

Today, I opened my eyes to find myself in Academy City, with Misaka Mikoto pointing her Railgun straight at me.

Bros, what do I do? Waiting online, kinda urgent.

PS: Friendly reminder—please throw your brain away before reading this.

PPS: The lack of logic is the logic of this story.

PPPS: ...Brains all gone? Then come on in.

At the annual Tianming Annual Meeting, many Valkyries were discussing who would be the strongest Valkyrie of the year as voted by the bigwigs of Tianming.

"The probability of Lady Yulandel being the one is very high. After all, she is the strongest Valkyrie in the history of our destiny."

"It's not impossible, Lady Theresa, right?"

"Could it be Lady Rita?"

"Wow, who is Ye Chu?"

(Multiple female protagonists, no stallions, no ooc, slight secondary settings)

I thought it was the main god space, but it turned out to be the subspace.

I thought it was the main god light ball, but it turned out to be the emperor light ball.

Others rely on development for technology, but he relies on archaeology.

One day, while he was doing archaeology, he was suddenly invited to a "hyperdimensional channel".

Re:CREATORS:......

Traveling through Naruto and becoming a civilian orphan,

How can you survive in the war-torn ninja world?

No golden fingers, no bloodline limits, no family resources.

How can we dance in this chaotic world?

…

"Of all those who have fought me, you are undoubtedly the strongest, even stronger than Hashirama! Come on, young man! Dance to your heart's content!"

"Dancing? I'll blow your head off!"

In the Holy Grail War, who holds the artifact and beats everything?

Gilgamesh! It’s yellow hair! It’s yellow hair!

In the face of catastrophe, who can stand up and save the world?

Kurosaki Ichigo! Uzumaki Naruto! It’s yellow hair! It’s yellow hair! It’s yellow hair!

In front of the heroine, who can counterattack, the bull-headed protagonist?

It’s yellow hair! It’s yellow hair!

Who is Huangmao?

I am Huangmao!

He transformed into thousands of forms and reincarnated through countless worlds.

Every reincarnation is the implementation of one’s own path to enlightenment.

In a world of one person, one seeks the truth and the fusion of nature and destiny, opening up the path to immortality.

In the world of Naruto, trace the origin of your bloodline and create your own martial arts.

Ghosts destroy the world, evil ghosts eat people, the seven deadly sins, the suffering of all living beings...

All the heavens and worlds, infinite reincarnation.

I have a heart to prove my truth, for ghosts, immortals, humans, Asuras, demons... I will never give up.

This is a legend of the heavens.

Infinite competitive brawl, a clash of dimensions!

Minato Namikaze VS Borsalino - the clash of Flying Thunder God and the Pikachu Fruit.

Immortal Hulk vs. Saitama. —The thrill of fist-to-flesh combat. We are the nourishment for each other's progress!

Double Battle! The legends of Naruto and Pirates gather together!

Infinite brawl does not mean fighting all the time; there are many ways to decide the outcome.

Who will come out on top in the chef competition?

Is the champion of the Ten Thousand Worlds Beast Taming Tournament decided by the Pokémon world?

Will Tang Haishen feel embarrassed when the protagonists of all the fantasy stories meet?

This is the infinite arena!

(If you're going to watch it, you're here for the fun. If you're in the comments section, you're here for the fight. The comments section is so filled with smoke that even a powerful emperor like me wouldn't dare to set foot in it.)

In Zoroastrianism, the mother of evil is the source of all evil and darkness!

It is said that she created the six demons of "malice", "chaos", "aging", "betrayal", "weakness" and "destruction"!

Saigo, who obtained the spirit of the 'mother of evil' in the box garden, became the 'supreme master' in Overlord;

Looking at the 'ruler of death', 'witch of the gap', 'demon of Teyvat', 'big demon of Gensokyo', 'demon of dxd', 'creator of the demon pillar' and others around him;

Saigo is sure that he has established the name of 'evil god';

In this case, he wants to shout out at the top of his lungs - God is dead!

Luke is torn apart!

An Optimus Prime, which was rushing to achieve its performance at the end of the year, mercilessly crushed Luke into countless pieces.

The Lukes who gathered together began to try various ways to save themselves in order to survive in the other world.

However, they seemed a bit extreme.

Luke under One Person: "Looking for dragons and dividing gold, look at the mountains, and each layer of winding is a level of hurdle. Sister Baoer, there is a treasure here, get the shovel!"

Dragon Luke: "Eliminate human tyranny, the earth belongs to the Dragon King. Welcome the new emperor Jörmungandr to the throne!"

Pirate King Luke: "Although I deceive my superiors and subordinates, I am greedy for money and lustful, but I am really a good navy!"

Marvel Luke: "In this empty world without heroes and villains, from today on, I will stand in the sky!"

All Luke: "It's not me who is wrong, but this world. I must be a normal person!"

One Person, Conan, Harry Potter, Dead Fire Sea, Marvel, etc...

In short, a lunatic saves the world, you know.
