2 Chapter 1: Brothers

Kibutsuji Muzan,

The main antagonist of Kimetsu No Yaiba,

He is a demon,

Not an evil human scum that got called a demon, a real demon, a demon in the literal sense of the word.

He is the first of his kind, the progenitor of many other demons...He is also the strongest of his kind, this is a fact considering he is the original demon.

The demon that slaughtered Kamado Tanjirou's family members and turned Kamado Nezuko into a demon.

The demon king, the OG..

Alright I'm rambling too much..

As I sit on top of the snowy ground, I tried organizing my thoughts of the myriads of memories that I've just assimilated with just now.

"This feels so weird, this process of receiving the former owner of this body's memories is surreal. It's like you're living through a movie scene where you know it's fake but you think it's as real as possible. It just doesn't make any sense!"

I held my hands again as a few groans escaped my mouth.

"This is frustrating! Why didn't those webnovels about reincarnation in another different body explain something like this? I'm so confused!"

I took a deep breath as I tried to calm down, in, out, in and out.

"*phew*, okay, let's see..The former owner is a young man who wants to become a swordsman and got his parents to pay instructors to teach him the way of the sword and martial arts, Ate nutritious foods and trained daily since I was 8 years old and died when he reached 15 years old."

Oh and also his name is Kibutsuji Yamato..the little brother of Kibutsuji Muzan, Go figure.

He was a child prodigy as they call it.

A natural in the art of swords, a calm and gentle personality

Loved by everyone in the family

His father wanted him to become the heir to the family, but the thing is he is the second child, the first child by birthright should be the heir to the family back in the olden days.

But because his talent shone brightly, father and the rest of the family made me the priority and ignored my-his elder brother, Kibutsuji Muzan..

This is because he was diagnosed with a disease that would kill him before he reached the age of 20, thus labeling him with a certain death stamp in front of everyone's eyes.

Now, it doesn't mean the family isolated him, they still love him but their priorities are just on him first, Muzan second.

That is before they found a doctor that managed to heal Muzan, after he was healed. He became stronger, healthier and better physically. He was growing stronger day by day and he also started joining me-him in martial arts training and not long after the instructors and the family found out that Muzan is also a prodigy, hell..he's even better than his brother!

He is also getting progressively handsome and he dabbled in the arts and academics, thus making the family prioritize him again and me second, as it should be.

Now I'm not saying that he hates Muzan, just frustrated at the family's fickle attention and the change of attitude towards him.

But he noticed that Muzan started to avoid the sunlight and won't go outside when ther's a sun except wearing umbrella and coverting every nook and cranny of his body the clothes to avoid being hit directly by the sunlight.

He also started becoming...abnormally strong, hell, he once cut a boulder apart with his training sword..

He got suspicious and and started to investigate about Muzan.

One day, when he went to the bathroom to pee, he caught a smell of blood in the air.

Due to his training, his 5 senses are honed, not to perfection but to quite the high level for his age. He went to investigate the source of the smell and reached the corner of the courtyard, near the storeroom. The door was slightly ajar and he peeked inside and there he saw muzan being illuminated by the moonlight from the window of the room.

Kneeling on the red floor..that's not right that's a puddle..a..a puddle..of..blood..

He then saw a body lying on the floor, her blood pooling beneath her and painting the floor crimson, like a cream of red velvet on a chocolate cake.

He nearly puked but manage to hold it back, sadly, Muzan with his superhearing senses noticed the slight gagging sound that he heard and turned his head around so fast and stared at his little brother's eyes, two plum red colored eyes with vertical pupils stared at two crimson red eyes with black round pupils that started to dilate, perhaps out of shock or fear or both.

As he scrambled backwards, he turned around and started running back to his quarters, sadly that will never happen.

He heard a slamming sound behind him, 'the door has been slammed opened' he thought, he then heard a sound of something cutting the air and felt movement behind him by the disturbance of air flow, he ducked and rolled to his right and barely managed to avoid Muzan's pounce.

He rolled a bit on the snow and quickly stood up from his position, 'gotta protect myself and stand up to ensure I don't get pounced on again'. Then he looked in front of him and saw his brother just standing there....menacingly and staring at him.

He started questioning his brother what happened to the lady in the storeroom, did he kill her and what was he doing near her body.

He heard an amused chuckle..

He lifted his head..

And saw Muzan looking at him playfully while smirking and playing with his long purple nails, he had fanglike teeths, but what caught his attention is Muzan's lips

…Get yer mind outta the gutter, he's not gay and he's not having sexual thought about Muzan either

No,no, what he saw was blood..crimson..blood on Muzan's lips and dripping down his chin, just like a dog's saliva after eating a hearty meal or just plain animal tearing through meat and bones..

"Why are your lips blood-"

He got struck by an ephiphany, middle of the night, dead body in the storeroom, red blood., kneeling near the body, muzan's lips..those teeeths….the…bLoOd…those TeeTHS….THE BLOODS!!!! THOSE TEETHS AND NAILS!!!

"AHhhhhHHHHHHHhhHHHhhHHHHHHH!!!!"

He screamed as he got struck by fear, rage and disgust as he realized what had occurred in the store room..his brother..Kibutsuji Muzan was a demon!

He then heard a mocking voice, "*chuckle* What's wrong little brother? You look like you've just saw a demon"

He then grit his teeth, swallow his disgust and started shouting at Muzan, no..at that..'thing'

"You damn demon, where is my brother? What have you done to him!?"

"*chuckle*I rejected my humanity, yamato!!"

"What? What are you saying?!...No…YOU'RE NOT MY BROTHER! YOU'RE AN ABOMINATION!! A MONSTER!!!"

Then he heard an imaginary snapping sound inside Muzan's head, before seeing a blurry shadow and getting hit by something.

He felt the air left his lungs as he got thrown back but befor he could fly away, he felt something grabbed his hair, killing his momentum.

"ARGH!!" He shouted in pained as he got lifted by his hair.

"What did you say?" He heard a voice teetering on the edge of wrath asking him.

He struggled to look at the face of the speaker and saw that their face are very close to each other.

"What did you just call me?" The speaker asked again.

"Ugh, I'll say it as many times as you like, YOU'RE AN ABOMINATION!! A MONSTER!!"

He then saw the eyes of the man were shaking as his face turned from calm to angry to vengeful then to angry and gradually calming down and finally becoming stoic again.

A few moments passed by with only silence before he heard Muzan speaking.

"If you hate being an abomination and blood that much..I'll give you what you despise then"

"Wait, what are y- *cough*" He was trying to speak but got cut of by the feeling of being hit by something, like being punch in the solar plexus by his martial arts instructors.

He slowly look to his abdomen and saw a hand piercing into his body, the hand didn't make a hole but instead stayed inside his body.

Before he could feel anything, he felt something entering his body and he started to spasm and making gargling noise in his head..

"I tried this once before, a way to torture someone before ultimately killing them, take it, the blood of an 'abomination´ and enjoy dying as an abomination, in forms of heap and flesh"

My spasm started to intensify as he saw the surroundings blur by before we reached the edge of cliff. Muzan kept helding his brother's head while he move around erratically. He heard Muzan's voice while his consciousness kept blacking out.

"Farewell brother, enjoy your final moments" before he heard a sound of cutting air and feeling the wind hit my body before being pulled down by gravity to the bottom of the valley, the last thing he saw was the gray sky and falling snow, as if the sky was crying for my death, he closed his eyes as he lose his consciousness and the last thing he felt was hitting the cold, snowy ground….

~A long time later

I woke up and slowly tried to stand up and look all around me..

"Snow..snow all over me.."
