In a forest on a stormy night ,a man holding a baby was running through the forest as fast as he could
*waaaaa* the baby cried
"Shhh please stop crying or he'll find us , he'll find you ,she is holding him off right now so *cries* we just have to survive till the sun rises , i feel ashamed of myself for running like this ,both as a husband and a demon slayer"

????:"Ouch th-that hurt" said a white haired 14 year old while clutching his stomach
"HAKU IF YOU FALL LIKE THAT DURING A BATTLE YOU'D DIE ON THE SPOT AND DON'T STOP THE TOTAL CONCENTRATION BREATHING ON PURPOSE ,HOW CAN YOU BECOME A DEMON SLAYER LIKE THAT!"
Haku:"I don't want to become a demon slayer! I've had it with this training ,ever since i was a child you put me through that hellish training ,breathing this and breathing that, I'm done!"
Haku says and runs into the woods
Haku's father walks out of the house and sighs
villager:"Fuma-san ,Haku ran away again huh ,don't worry he'll come back like always"
"*sigh* that rebellious child always does this"
villager:"Fuma-san i think you're just being a bit harsh on Haku, he's still a kid and kids need to be spoiled once in a while"
"Maybe you're right ,he is very different compared to normal children ,so much that even the village kids don't want to get close to him"
Villager:"Well I'm pretty jealous of him ,having a powerful body like his ,but his sun allergy makes you think he maybe a demon right hahaha"
"Hahahhaha" Haku's father laughs nervously
?????:"Excuse me is this mr.fuma's house"
"hmm yes who...RUN NOW!"
villager:"What do yo_"
then his head fell on the ground
"Never thought I'd see you again" Haku's father said while gripping his katana

Haku was running through the forest at night, then he stopped and climbed a tree
Haku:"I guess I'll sleep here"
*sigh*
"why does he want me to become a demon slayer that much,and also why did i have to be talented with the sword if i wasn't then maybe i wouldn't be here like this"
'the only time he ever praised me was when i made the *Breath of blood*'
then he went to sleep
hours later he's woken up by the feeling of pain and itching on his skin
Haku:"Damn it , stupid sun allergy *sigh* i guess I'll go back now ,but I'll refuse anymore training "
he then jumps of the tree and heads back home using his black kimono as an umbrella
when he gets back ,his arms go limp and he then falls to his knees from what he sees
corpses everywhere
Haku:"Father!"
he says running to his home as fast as he could
Haku:"Father!"
when he reached his house he found his father's body with it's head missing
and limbs cut off
Haku:"FATHER!" he yells while crying
"PLEASE GOD LET THIS BE A NIGHTMARE I'D DO ANYTHING PLEASE JUST BRING HIM BACK I'M SORRY I EVER SAID ANYTHING ,I DON'T CARE IF I HAVE TO SUFFER A HUNDRED TIMES THAT HELLISH TRAINING PLEASE!!! *Sob* please" he said with tears flowing out of his eyes
it took him hours of crying to finally accept the reality that his father isn't coming back
after burying his father and the rest of the village he entered his house and sat in front of a box
Haku:"I never thought I'd open it so soon"
it was a box his father told him to open once he dies
Opening the box he found inside it a nichirin blade and a letter
Haku opened the letter and began reading it
'Haku if you're reading this then i must've died , if i have been killed then it means that he found me Muzan Kibitsuji the leader of the demons ,he's also the one who killed your mother,he killed her because she betrayed him and he killed me because i was her husband, your mother was a demon, which means yes ,you aren't human nor are you a demon but something in the middle ,which is why your *breath of blood* is possible ,it was your unconscious usage of blood arts that you were able to do it
so my son i give the choice ,if you want to live a peaceful life then run away and don't let him know of your existence or you can hunt him down the choice is yours ,if you choose to fight Muzan then use this sword it's made specifically to help your *breath of blood* and go slay him as a demon slayer'
Haku Fuma then made his choice and held the sword as it's blade turned dark red
on that day swore to end Muzan.
