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!

Suibian! A young man with a very casual name, living a casual life. Then, he was casually killed by a flower pot, and thus entered the world of Demon Slayer! He became Tokito Muichiro's older brother, Tokito Ichiro! From then on, his life began to be more than casual...

When Tanjiro Kamado stepped into Nada Spider Mountain, a huge screen appeared in the sky.

The question-and-answer system has officially started. As long as you answer the questions, you can get various rewards, including but not limited to "resurrection", "turning back into a human", "blue red spider lily", etc., to solve your unsatisfactory wishes!

After resurrecting his wife, Akaza said: "I am Fist Pillar. Muzan, I will *your Sage!"

Shinobu Kocho: "I have a gentle personality? Wait until I get the reward and you will know what a killing angel is [sinister smile]."

Agatsuma Zenitsu: "Grandpa was forced to commit suicide? I'll show you what a fucking thunder pillar is! What a fucking thunder pillar is!"

Douma: "The punishment is to experience extreme pain? There's such a good thing?!"

Mitsuri Kanroji: "Eh?! Mr. Iguro likes me? Then I'll confess right now!!!"

Kokushibo: "I want to resurrect Yunichi. Even if Muzan comes, he can't stop me. I said it!"; Muzan: "You are really my living father."

Tomioka Giyu: "I want to be the most popular person [cold face]."

Muzan Kibutsuji: "The reward is a blue Higanbana?! As long as I can get it, I'll do anything~"

......

Is the plot difficult to accept?

Through questions and answers, all of them were changed to perfect endings!

(cp: After chapter 20, I will not promote the official version, only Komare and Snakereen)

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.

Travel through Demon Slayer and merge with Muzan Kibutsuji!

Reorganize the Twelve Demon Moons, run rampant in Tokyo Prefecture, and terrorize Japan!

End the Demon Slayer Corps, liquidate Ubuyashiki, and aim at Taisho Tenkō!

Strategy of thousands of ghosts, swallowing the world, only I am Yue Yan!
