Let's take a look at the Demon Slayer fanfiction

Ashina, the land of reeds, half-knelt on the ground, looking at Kuro who was unconscious in front of him.

......

"Please live on as a human being."

He swung the immortal sword "Bai Lei" on his neck, and the blood that should have splashed out turned into flying cherry blossoms floating on the reeds.

During the Taisho period, in the alleys of a remote town, a lifeless body glowed with a pink divine light.

"resurrection"

A lifeless, thin figure sat up from the rain.

"Where is this..."

At this point, the Son of God and his Ninja Wolf, although in two different worlds, are both reborn at this moment!

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!

Traveling through the world of Demon Slayer, Shigure opens the role-playing system of the universe.

The higher the missions completed and the degree of character restoration, the stronger the power gained.

The first task required at the beginning is Bai'e.

"? Bai'e beats Wuzhan? Doesn't having hands do that?"

"Nanook... uh no, Muzan Kibutsuji, I bring destruction upon you!"

Muzan Kibutsuji: "No red blade? No markings? Are you also a pillar?"

Shigure: "Pillar?... Pillars are considered pillars."...

Muzan Kibutsuji: "It's useless. Unless I wait until the sun rises, I can be resurrected even if only a piece of flesh is left..."

"I am"

"?"

"The blazing sun will eventually rise!"

Si Jinkun, who traveled to the Demon Slayer world, shouted at the beginning: I don’t want to be a human being anymore!

He went completely crazy after arriving in the world of Demon Slayer

That shadow that has lingered for a thousand years—Muzan Kibutsuji! That pitiful creature who cowers in fear because of the curse, that false king who vainly seeks immortality!

All his struggles and blood ghost arts became futile jokes in front of Si Jinkun's ultimate body that combined the curse of the stone ghost face and the essence of countless ghosts!

He treats Wuzan as a high-end bun

It also forced the demons and the Demon Slayer Corps to join forces for the only time in a hundred years.

Many years later, Si Jinkun, who had already become a JO-level creature, looked at the world he had ruined and fell into deep thought.

On the night of Kiritsugu's death, Shirou fell asleep and woke up to a new world.

There are ghosts here, and there are swordsmen who kill ghosts.

From now on, partners of justice are no longer a borrowed slogan!

But it is a creed that you carry out throughout your life!

Ghost King, give me your life!

Infinite Holy Grail War?

Run through every one of them!

Lin Guang travels through the world of Demon Slayer and awakens the Super Treasure Chest System! In Demon Slayer, slaying demons unlocks treasure chests; defeating the navy and celestial dragons unlocks treasure chests; and defeating enemies unlocks treasure chests in Naruto. Thus, Lin Guang continues to unlock treasure chests, conquering the world!

After traveling through Demon Slayer eighteen years ago, Kamishiro Mitsuteru thought this was just an ordinary ancient world.

Until the night of the blood moon, the evil spirits tore his warm home apart.

When you are on the verge of death, the sign-in system is activated!

[Congratulations to the host for receiving the Newbie Gift Pack: Nature-type Sparkling Fruit! ]

The body instinctively transforms into elements to avoid the fatal blow!

He raised his hand and pointed, and the holy light penetrated the evil ghost, evaporating it instantly!

The loud noise attracted the dying Kanae Butterfly, and the Second Upper Moon, Douma, who was standing in front of her.

Under Kanae's desperate gaze, Kamishiro Kouki transformed into a beam of light and kicked Douma half of his body away at the speed of light. He sneered and said, "Sorry to bother you. But you can die now."

If a time traveler wants to gain strength quickly, what's the best way? Rhodes thinks the easiest thing is to take refuge in the arms of the Burning Legion's CEO.

Lord Sargeras has always been very generous to those who voluntarily surrender, and does not hesitate to grant powerful evil powers.

Rhodes began to deceive the entire Burning Legion and Sargeras to work for him to conquer the world.

One Piece World: Rhodes "Drink, Kaido, this is your fate, the fate of all you pirates."

World of Naruto: Rhodes "The Legion is invincible, the sacred tree is ours, everything belongs to the Legion."

Monster World: Rhodes "The legion is unstoppable, use evil energy to transform these titan beasts."

Devil May Cry World: Rhodes "Slave the demons, Spartan Twins, you must fight for the Legion."

Bayonetta World: Rhodes "Beauty! Are you interested in joining the Burning Legion? The Legion offers generous benefits and benefits."

When you have enough strength, hum! How can a real man live under others for a long time?

In the Marvel world, Mr. Sha is tricked into grabbing the infinite stones.

Mr. Sa encountered a group of... Mr. Sa's pawns.

Rest in peace, Mr. Sa, I will inherit everything from you, and I will inherit the great cause of the legion.

Tianji transmigrated to the world of Bleach. Knowing Bleach well, he originally thought he could make a name for himself, but fate played a joke on him. Tianji transmigrated to 1,500 years before the main storyline. At this time, there was no Shinigami Academy, and even the Gotei 13 had not yet been formed. The only one protecting the Soul King was the Zero Division, which only had two members.

That's not all. I thought I could finally enjoy life after defeating the Grim Reaper, but then I was transported to another world.
