(This is a novel written for my own reading, including some other people's works. I'm just sharing it here for everyone to see. If you see a part you don't like, just leave.)

A 21st-century college student named Xuanming was struck by lightning while passing by a large tree during a thunderstorm and was transported to the world of "Demon Slayer". In this world, he became a disciple of Kuwashima Jigoro and learned the Breath of Lightning. Due to his unparalleled talent, he became an undisputed strongman of the Demon Slayer Corps. Watch how he makes up for the regrets of reading the original work and leads the Demon Slayer Corps to kill Muzan!

The introduction is insufficient; please proceed to the main text.

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!

I'm willing to die for this natural long-haired, blue-eyed, white-haired beauty

Note: The title of the book is seriously inconsistent with the content!

It's normal to see some weird comments because I'm too lazy to delete them.

You can call me a piece of shit (although it is true) but please be lenient with me.

"My life was dark and I couldn't see the future until I met him."

A beautiful (should?) story of mutual redemption (maybe?)

It's quite plain, just a short story before bed, with some essays and prose occasionally

Natural markings + natural transparency + complete sun breathing = Muzan's new father

(Not a time travel story, the protagonist does not know the plot)

Chiba Yang, whose everything was taken away by the demons, joined the Demon Slayer Corps at the invitation of the Flame Pillar and became the stepson of the Flame Pillar. From then on, all the demons ushered in their nightmare.

The protagonist is a descendant of the Jigoku clan. He looks very similar to Yoriichi. He comprehended the Breathing of the Sun on his own and created his own sword skills.

To end the curse that had plagued his family for millennia, he chose the darkest path.

As the 97th Master of the Demon Slayer Corps, Kagaya Ubuyashiki has always been a gentle and revered leader in the hearts of all his members. However, as the curse increasingly erodes his life, and as he foresees that his daughters will repeat the same mistakes, on the verge of despair, he makes a choice that will shake the world—to make a deal with Muzan Kibutsuji and become the most hidden Upper Moon Zero.

By day, he remains the lord who guides everyone in the fight against demons; by night, however, he is loyal to his millennia-old nemesis. When the truth is revealed on the eve of the final battle, the Demon Slayer Corps' faith crumbles overnight. The former "father" becomes the most despicable traitor, and the Pillars who once swore their undying loyalty turn their blades against each other.

But at the end of this sin-soaked road, does Kagaya hold a trump card that can turn the tide for a thousand years? When wisteria blossoms alongside bloodshed, this game of chess that began with betrayal will finally reach a shocking conclusion.

[Orange + Slow Burn + Healing + Single Female Lead] Transmigrated into the body of Yoriichi Tsugikuni, the pinnacle of Demon Slayer, she joins the Demon Slayer Corps, creates her own Snow Breathing technique, and becomes the second swordsman after Yoriichi to master the Demon Slayer Mark. Yuuko originally wanted to change Iwakatsu's future as a demon, but unexpectedly… Iwakatsu: Yuuko, you should become a demon too. … Note before reading: This book is tentatively set to have a single female lead, Orange. The female lead is Shinobu Kocho. If you don't like this, please don't read.

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!

A boy named Uchiha Mei lost his parents to demons when he was ten years old. He met the Flame Pillar, Rengoku Makijuro, and became his disciple, possessing extraordinary talent. He formed a bond with the Flower Pillar, Kocho Kanae, becoming Tanjiro's teacher. He arrived in time to fight Child Demon when Kanae was attacked. He instinctively killed Child Demon, but Kanae was seriously injured. To ensure Kanae's safety, he inadvertently allowed Child Demon to escape. He later became the Fiend Pillar.

Ever since the Breathing of Fire was developed during the Warring States Period, more than 80% of the Flame Pillars have carried the name of Purgatory.

Even Rengoku Kyojuro, the last Flame Pillar of the Taisho period, gave up his own dawn for the dawn of others.

But if history diverges,

That one,

It keeps growing upwards,

The flower called "Purgatory"

Inadvertently, a fruit was born, but it was helplessly abandoned. Who can guarantee that it will sprout again as a seed in the shade and grow in a deformed form...

Or will it just be a fallen petal, transforming into nutrients to dedicate itself to the growth of future generations...

What if you encounter Muzan at the start and become a demon? Before you lies the demon who doesn't eat humans, the heir to the Forest Breathing, the Pillar who strikes fear in countless demons, the honorary founder of the Butterfly House, a staunch supporter of Dorayaki, the poop-scooper of Shiba Inu Enji, the idol of the male and female members of the Demon Slayer Corps, and the trusted senior of all the Pillars: the Forest Pillar - Moriki Shinichi! [Not a system! Not a cool story! Growth-oriented! Single female protagonist! Don't read if you mind, the author is sensitive, so please don't criticize if you don't like it.]
