Wisteria

Prologue

His name was Tanjiro Kamado.

Or at least, that's what it used to be.

Before the chaos of demons, he was Tanjiro. He used to sell coal to his village and keep company to his family. He used to play with his siblings in the snow and sit on the balcony as he watched his father perform a special ritual. He used to talk to the villages as he sold coal, happily knowing every person.

But that was in the past.

He was trapped now, in what used to be his body. He could barely recognise himself now. A jet-black colour replaced his flaming red hair and a pair of slit pupils. He was significantly taller with paler skin and a pair of fangs. His nails were long and sharp, just like his fingers. He was everything he hated to be.

He was the one person he desperately despised.

He no longer referred to himself as Tanjiro.

He was Muzan now.

He was no longer the master of his flesh. He was reduced to a spectator to what used to be his body. He was now watching Muzan control his former body.

Muzan quietly walked down the mountain, walking past Tanjiro's old home. The painful memories struck Tanjiro. He remembered the fateful day he saw his family lying in a pool of cold blood. He remembered Nezuko and the desperation to keep her alive. He remembered everything he lost.

Now's not the time. His mind snapped. Being tethered to the Demon King meant he felt what you felt and vice versa. But Tanjiro didn't listen. He did quite the opposite, remembering every detail of every bit of suffering in his life. Unluckily for him, Muzan struck his unrecognisable face which caused the two to snap back into reality.

As Muzan began to reach the bottom of the mountain, Tanjiro could only feel a sense of defeat. Even if he was a spectating soul, that didn't limit Muzan's powers or threats. The fact that Tanjiro was alive was out of pure obedience. Muzan could have crushed his soul to a million pieces, just to squeeze the damn brat out of his mind. However, Tanjiro had the information he needed.

He needed the blue spider lily, and that's why he was here.

As Muzan trudged through the mountainous terrain, Tanjiro felt his soul shake. This was the moment immortality was achieved or unsuccessful. The soft sound of a river flowing made Muzan stop in his tracks. He was close, he knew it.

Past the bushes and trees, only a few feet away, was a small river.

Muzan's eyes gleamed in interest as he took a step forward, taking a further inspection of the river. Lying on the riverbed was a crowd of flowers.

Blue Spider Lilies.

We've lost. Tanjiro thought, feeling all hope leave his body. The Demon King chuckled and quietly took a step forward, kneeling down to gingerly touch the flowers. The flower that cured and ruined his health condition. However, Tanjiro could only ponder. He doesn't need the flowers. He has my body. That's enough to stand the sunlight. So why, why on earth, does he need the flowers? Tanjiro thought.

With the snap of his fingers, a flame grew on his fingertips. What are you doing?! Tanjiro asked in a panicked tone. Muzan ignored the panicked soul, brushing his finger against the petals of the flowers. The curse. The very curse that caused him to be this way. Oh, how he wished he never met this cursed flower. How he wished he never knew this flower.

Yet, this flower gave him life. And here he was, burning the very flower that gave him what he so desperately wanted. As the bed of flowers erupted into flames, Tanjiro's confusion grew. Why burn the flowers-

Oh.

No life outside his legion would exist.

No cures for him or his subjects. No way to overpower his immortality. No way to make him the former filth known as a human.

No one to overpower him.

As Muzan watched the flowers burn, a sense of satisfaction grew over him. How he'd laugh at the face of those pitiful humans begging for their life, just like he did to the heavens.

Tanjiro's soul sank with despair. There was no way to salvage Muzan's morality. But then again, one thousand years of killing and eating humans isn't salvageable either. All Tanjiro knew was that humanity was screwed without this single flower.

Tanjiro's despair grew tighter, just like the pressure around his soul. He felt like his soul was getting crushed to insignificant pieces of dust. Oh, how this was all worthless...

He was getting crushed. Looking down at himself, he noticed his soul crumbling into dust. Why?! He exclaimed, trying to scoop the floating particles away. No, no, no! Not now! He wasn't supposed to die. His soul wasn't supposed to die. Yet, it was crumbling in front of his eyes...

"No... No, no, NO! WHAT ARE YOU DOING?!" Tanjiro shrieked to the Demon King. The Demon only smiled as the pressure grew.

"Goodbye, Tanjiro Kamado. I do wish you the best." Muzan replied in a sickly sarcastic tone. I mean, Muzan wasn't going to keep Tanjiro, God no. He knew where the blue spider lilies were now, so what use was Tanjiro? No, this was Muzan's body now.

He was no longer Tanjiro. Truly, no longer Tanjiro.

He was Muzan Kibutsuji, and forever Muzan Kibutsuji. He was the Demon King, the Savior to humanity, the powerful one.

The immortal one. 

The heavens would bow to a name so great he would become a God. He would have the whole world quake by screaming out his name.

The unstoppable one.

As Tanjiro's soul faded, so did the last of Muzan's humanity. No cure for demons, no humanity in the Demon King, and no Demon Slayers to oppose him...

No one to stop him.

And how he loved that. How he loved no one opposing him. How he loved to show he was the ruler. How he loved to show he was alive. Those thousands of years proved to be of use. From the very moment he was born to now, he was alive. How that was such a wonderful gift he was going to use.

And now he would give life to everyone. He would bless the whole world with his power and knowledge. He would be blessed with praise from everyone across the world.

He would bless the world with life.

A new life.

Hey Gang Gang. Yeah, here is a Demon Slayer fanfiction. I'm bored as shit and decided to rewrite it. So enjoy this shitfest of a fanfic.

BTW: Yes, this will have my own take/ideas/worldbuilding. I have a few problems with the original worldbuilding and I want to chuck it in here. Besides, this is like an offshoot of the original. You can kind of guess where this fanfic is taking place (which arc, basically), but I don't care.

Love yall.

Also, yes, like my MAO ZEDONG (GLORY TO THE CCP 🔥🔥🔥🧧🧧👲👲🥰🥰😍😍🍜🍜) book, writing is a hobby. I don't care if it's shit or not. I haven't written in a while, so yet, it will be unironically shit.

I literally wrote this out at like 10:30 at night, but who cares.

Love yall again <3

Enjoy the book :)
