Chapter 8: Y/N's Family

(500 years ago)

Muzan: he's perfect
???: he is isn't he
My mother smiles at Muzan as smiles back
???: what should we name him?
Muzan: let's name him Morbius
???: Morbius? Seems a little Demonic don't you think?
Muzan: we'll what do you want to name him?
???: let's name him Y/N!
Muzan: are you sure about this name?
???: yes I'm sure honey
She smiles as Doma runs in looking at Muzan
Muzan: this better be good
Doma: I received reports that upper moon 6 is dead slain by the flame Hashira
Muzan: didn't the flame hashira die?
Doma: yes however a man under the name Rengoku Jigoku slain him
Muzan: I see, we must get the queen and my son out of here it's not safe anymore
Doma nods his head
Muzan: and come fworth
Doma steps forward and kneels in front of Muzan as he stabs his neck with his finger
Muzan: you are now upper moon 6, good luck
Doma gets up
Doma: thank you my lord, come on lady tamayo, we must go
Tamayo gets up holding baby Y/N until Tamayo runs the opposite direction holding you as Doma turns around confused.
Doma runs to the direction where Tamayo ran until he runs into a dead end Y/N at demon slayer headquarters crying. A hashira approaches the basket holding a note

Dear Demon Slayers,
I was married to Muzan Kibutsuji I now rebel and decide that this is time for me to strike back with his own blood, in this basket is his son, please take care of him and he'll help you serve your war to take Muzan down. Thank you, and I'll see you soon when I come with a cure.

Another hashira approaches behind him
Water Hashira: Jigoku, what is that?
Jigoku: get the master please.
(Present time)
I'm carrying Rengoku and Inosuke as Tanjiro is carrying Zenitsu, we arrive at the headquarters until master walks out.
Master: glad to see you are safe and alive!
He smiles as I hand Rengoku and Inosuke to the Kakushi
Y/N: why didn't you tell me?
Master: what?
Y/N: why didn't you tell me Tamayo is my mother?!
Tanjiro: whaaaaa?!
Y/N: I'm going to go visit her
Master: yeah about that. Come with me
I follow master until I stand in front of a grave stone marked with Lady Tamayo.
Master: Muzan used your abscess to kill your mother
I didn't know what to think or what to say I collapse to my Knees and just cry, it's all I can do
Nezuko comes out of the box and comes up to me and hugs me
Y/N: thank you Nezuko all of you, no matter what you guys are my family

(End of chapter 8, well 3 chapters to go, we went through so much but this story isn't over until we see Muzan' head on a pike. See you on the next chapter, chapter 9
