Background story:

Y/n or we were an Orphan, our parents were eaten and killed by a strong Demon at the age of 8 and we were captured and made into a kettle or a blood ag

The demons don't instantly eat us instead the demons slowly eat us by cutting our skin off slowly and eating them whole drinking our parent's blood

They did this to us every day while when part of our skins was gone they also slowly cut the meat off us and what them

It was so painful that we decide to shut off our emotions, and senses

And try to detach ourselves from reality to block the pain of everything

The demons don't want us to die so they treat us with some light bandage and stuff, and also force us to eat raw animal meat or human meat and sometime they gave us rotten meat

Every day was always like that... We have given up on the hope that someone would save us, we don't even know how long has it been since we were captured and held in this cave... Two weeks? One month? Five years? We don't know cause we always see darkness and no light

Every day hoping that someone would save us... Every day hoping that we have the power to kill those demons!... But our fragile, starving, and untrained body is so damm weak

One day we see a light! That was lit like fireworks!

A man saved us and killed the demon

The man cut off the Chain that chains us to the ceilings and walls

The man told us that he was a friend of our parents and has been trying to find the Demon who kill our parents

He apologized to us that it took two years for him to find the demon and find us who was captured

We hated him because he was so late but we were also grateful that he saved us, we want to cry yet tears won't come out...

We start living with that Man

When we tried to eat food it's all tasted bland even though the man said it taste sweet or spicy, Hot or Cold temperature 

We also once taste some for from the restaurant and see others liking the food and say it's good but for us, the food taste bland...

We lose our sense of temperature and taste

We are also unable to feel pain, we even once try to stab ourselves in the stomach just to feel pain and it worked a bit but after a few seconds we can't feel any pain anymore

The man who save us scolded us for stabbing ourself

We also have a hard time showing our emotions after shutting them off for a long time

After so much torture we just lost our will to live... No family, no dream, no senses of taste & temperature & pain , nothing we had nothing

The Man then tries to give us a purpose by being his disciples, starts teaching us about how to slay Demon, and teaching us about breathing style and stuff

We participate on exam to be a Demon Slayer and pass

After that we receive our Nichirin blade which was customized for our breathing styles and also designed and ordered by our Master

Now we can eat some food and they have a taste but only food we have eaten before and know how they taste like, this idea was suggested by our teacher

So if we eat an apple because we usually eat sweet taste apple then the apple will always taste sweet for us even if other people say it's sour or bitter because we only know the taste as to how we used to remember it taste like

We liked Donuts cause our parents used to make them with different variations of flavor so when we eat donuts we can just choose what flavor we want from our memories

One day went a demon slayer boy who was with a Demon when we tried to slay the Demon the human boy protected her asking to not kill her sister

We don't care as Demon is still Demon so we still going to kill the Demon whether it looks docile or not because for us all demons are bad and sh*t sadistic hungry crazy thing

As we were one step away from killing the Demon girl that is claimed to be the Male little sister well we don't care cause Demon is Demon

But Oyakata-Sama ordered us to stop

And...

So our journey starts! Will we be able to open up the Emotion that has been shut and learn that not all Demon is bad or will we still follow our rules that all Demon is bad because of the Trauma we have about Demon

--------

Breathing style:

Breath of Combustion:

A style that is a combination of fire and wind breathing

This style is ussualy focused on the immense short burst of energy and fast movement after seething the Blade from it sheet

This style also able to make Explosion as we swing our Blade at the Demon
