Apologies for the extremely late update. I was not able to finish anything. Hope you like this.

Being reborn as nice as you think it is, Finding yourself a fetus in a womb is definitely going to make you scream. This new life of mine is not exactly a privileged life. I live in what seems to be between feudal and modern Japan, because there are electricity poles and top hats.

My family belongs to a line of charcoal burners. For generations, our family's occupation is to manufacture charcoal and sell them. Not the best way to make a living, but it is an honest life. We don't earn much, but it is enough to keep us happy and that alone is enough for me. I think I'm blessed with this life. I have a pair of loving parents and soon-to-be siblings.

When I first came out of the womb, the first thing I saw was the loving gaze of a man whom I assumed was my father and an unconscious woman who was my mother. They were probably worrying about the fact that I wasn't crying, but they knew I was fine. All of them spoke in a strange language that I couldn't pinpoint. I sort of missed my old family and my old life but I quickly got over it.

I didn't like being a baby as I hardly had the strength to move myself and my height, or lack of it was also quite inconvenient. I tried to sit, and walk instead of waddling and crawling, I then would look at my my parents astonished faces. Needless to say, I was the talk of the town. I eventually got to accept my family. I was now Asahi Kamado, resident of this world. For some reason my mind tried to remember something, as if my surname was of incredible importance.

It was only when I was four when I realized.

My mother was currently pregnant with my brother.

"If it's a boy we'll name him Tanjiro, okay. Asahi take care of your younger brother okay"

Tanjiro. Tanjiro Kamado .

Demon Slayer.

I remembered all of it, I now understood. I then fell unconscious.

I always wanted to be a demon slayer after I watched the series, but now I really hated whatever higher being that placed me here and played such a cruel joke on me.

My parents were worried about what had happened to me. They wanted to get a doctor to take a look at me but I quickly dissuaded were sceptical at first but I soon convinced them.

Just when I truly accepted this as my new family and ready to start anew, I have to be saddled with the burden of foreknowledge. I still don't fully remember about the entire series but I could remember a few key points and events about the entire fandom. In a few years, my father would die. In a few more years, Muzan will arrive.

Everyone except for Tanjiro and the still unborn Nezuko will die.

I never felt more helpless. I don't want them to die, but what can I do? It's Muzan we are talking about. No one but Yoriichi can kill him alone.

What should I do? What can I do?

My answer soon came. There is still something that I can do.

As the oldest son to the family, I am required to learn the Dance of the Fire God, something passed on from father to son in every generation alongside the hanafuda earrings. I had seen my father using this to dance from sunset to sunrise every year, I had no idea why that didn't click within my mind until I found out just where I had been reincarnated to.

As of now, I'm the only one who knows the true identity of the Dance of the Fire God, The Breath of the Sun. In this world, I am four years older than Tanjiro. I don't know how or why I came into the Kamado family and how I ended up as the oldest son, but the mere thought of me being the oldest and what the future entails made me feel a strong sense of emotions I had never felt before.

I really want to protect them. Tanjiro, Nezuko, and my unborn siblings. I have no idea why I felt this way just by staring at my mother's pregnant belly but I just did.

I will protect this family no matter what it takes. I may fail. Muzan may still come and kill everyone I had come to love no matter how hard I tried but I will try.

And so, at the age of four when baby Tanjiro arrived into this world, I asked my father to teach me the Dance of the Fire God, saying that it looks really pretty and I want to learn how to do the dance with him someday.

For the first time, I never told a complete lie. It's true that a part of me wanted to dance with him in the ritual ceremony every new year. Looking at the sleeping Tanjiro in my arms further affirm this feeling in my heart.

I want to protect him.

Tanjiro, the protagonist of a fictional story or not, I don't care. My future siblings, side characters of a fictional story or not, I don't care.I want my family to live, no matter what it takes on my end. They may be fictional characters in another life but right now, they are my family. Muzan absolutely cannot be allowed to touch them.

It is with these thoughts that I started to learn the Dance of the Fire God from my father at the age of four. He looked proud of me when I said that I want to learn the dance from him and a part of me doesn't want to disappoint him.

And so, I learnt how to dance.

I began to dance the Dance of the Fire God.

I can see why nobody ever mastered the Breath of the Sun. It's not easy. Just going through the motions makes you breathless. I have no idea how father could easily dance from sunset to sunrise every year without feeling anything else other than a slight case of exhaustion.

It is then I began to realise why people always said that the devil's in the details. Physical requirements when it comes to the user's body aside, The Breath of the Sun could only truly be completed when you pay attention to the details. The angle at which you place your foot, every single breath you take in and release, how long and how short the breaths are, how high or low you raise your arms, how much strength you place in your arms. There are so many variables required to be done right in The Breath of the Sun to be able to truly call yourself a master of it. Just one single detail off and the dance cannot be possibly completed seamlessly.

But I have to do this. This is the only thing I have now that can possibly help me to protect my family from the danger that I'm sure will come someday. As of now, I don't have another option. The one fortunate thing that happened is that I ended up having a genuine love for The Breath of the Sun. In my spare time all I ever do is to practice Dance of the Fire God, to the point that my parents teased me for having an obsession with it. It's true, I had an obsession and motive for learning how to dance the Dance of the Fire God but thankfully, that obsession turned into genuine passion.

I still wondered how my frail, sick father managed to do this.

And so, I continue to dance. When Nezuko arrived, I continued to dance. Over the years, Takeo, Hanako, Shigeru, Rokuta, they were born into the family one after the other and seeing their smiling faces made me reaffirm my beliefs

I will protect them against any harm.

I'm old enough to help out by then and so without a word, things like chopping firewood, going to town to sell charcoal and buying things for the family, I did as much as I could.

One day, my father will die. I don't know when and I don't know how soon, but he will die. After that, after an undetermined period of time, Muzan will kill my family.

I knew this was coming. I know there's no way to stop this from happening.

But there is no harm in trying, right?

There, done. The rest will be coming as soon as I can write them. Please do not force me to update as more often than not it kills the mood . If you find any problems in my writing please tell me. And don't forget to review, fav and follow.
