Chapter 1: As White As Snow

"Are you sure she's ready Katsuki? She's only 12" Yuki said. Worry clear in her voice.
"Don't worry Yuki. She's turning 13 soon so it's fine. She knows more then some 13 year olds! She'll be fine" Katsuki said in reassuring his wife.

Right now Y/n is going to be going on a business trip with her father. Y/n would feel excited, but she then started to worry.

Who will look after mom and Yuuken?
What if Yuuken starts to miss Y/n and give their mother a hard time?

What if someone brakes in and steels things while mom and Yuuken are in the house!

Now Y/n really didn't want to go now.
"Stop worrying" Y/n heard her fathers voice. She looked up to see him looking down at her with a confident smirk.

"How can I!? Pa, we'll be gone for nearly a whole week! What about Mom and Ken-ken?" Y/n asked with a worried look. Katsuki just pat Y/n's head
"They'll be fine. It's us you should worry about. We can't be late now, go say goodbye to your mother and brother"

Y/n nods and said goodbye to her mother and little brother. Before Yuki could say goodbye properly to her husband and daughter, they just hugged and left in a hurry.

They were very late for their train stop.

"Haha! Your getting old!" Y/n laughed as she was slowly passing by her father as the two ran to the train station.
"Oh shut it! I gave you those legs!"
He shouted back. Running faster.
The two were running at the same pace but were trying to out do the other.

"I won!" Katsuki shouted and laughed in victory. Y/n was trying to catch her breath. At first she was going at a fast pace, but she started to slow down the closer they got to the train station.

Y/n rolled her eyes
"Come on. Let's bord on the train"
Y/n huffed out. Her father laughed.

The two got on the train with no problem. They needed to head to the city for Katsuki to meet with a friend of his for business.

Y/n stared out of the window. A little bored from the long ride. Y/n then noticed her father was doing something.

She looked over to him and see him knitting?

"I didn't know you could knit" Y/n said, paying more attention to what her father was doing.

"Yes, I only do it when I'm bored and on my way to these trips. Wanna try?" He handed Y/n a f/c yarn ball. Y/n started to work on a little scarf. By the time she was done with it, she had forgotten how to tie the ends off to make it not undo itself

So she asked her father
"Hey Pa how do I- huh?"
Y/n turned to her father but when she saw what he was making she stopped herself.

It looked like a clothes for a baby.
"Uhh, I don't think that will be big enough for Yuuken Dad" Y/n pointed out

Katsuki chuckled
"Who said it was for Yuuken?"

Y/n frowns
". . . What?" She was confused. Her father sighed
"Never mind. I forget your slow"

5 minutes later

"OH! Oh my god! Mom's pregnant!"
Y/n said in realization. Katsuki rolled his eyes
"Yes. Slow poke" Katsuki said. causing Y/n to gasp from the insult.

When they arrived to the city. Y/n was in awe of how crazy and alive the place was. So much people were in one place and there was so much noise.
"Hold my hand" Katsuki demand.

Y/n took her fathers hand and the two walked through the crowd. She kept looking around with amazement as her father kept looking straight forward.

The deeper they got into town the less people were around. Soon they stopped at an inn and Y/n had straightened herself up and was also reminded by her father how she should act
"We are about to meet the winter Hashira. Be respectful to her, and if she may act a little too comfortable then just brush it off and answer politely to her questions. Alright?"

Y/n nods.

They both enter the room where the winter Hashira is temporarily staying.
"Ah! Mr. Kurosawa! I apologize for asking you on such short notice. And I also apologize for the sword"

A women with bright teal eyes and dark brown hair with tan skin was seen showing the older man a grin.
"It's alright, Kimi. At least you didn't burn along with that sword, let's just be happy your still alive" Katsuki said with a chuckle. Kimi laughed, she then noticed Y/n who was standing close to Katsuki.

Kimi's teal eyes met with Y/n's red ones.
"You must be Y/n. Hello I'm Sato Kimi, but please just address me as Kimi"
Kimi said with a smile.

Y/n bows slightly to show respect.

"Oh~ she's so cute! . . . . You know, Lord Tengen would love her" Kimi spoke the last part a little more quieter and more twords Katsuki.

Katsuki went silent. He looked over to his daughter who was staring at Kimi and admiring how buff she looks.

"Y/n. How about you go down stairs and get me and Kimi drinks" Katsuki said.
Y/n nods and left the room, her necklace jingling as she moved.

Katsuki sighed and looked back to Kimi
"You know, the first and last time Tengen saw and held my daughter was when she was 3. The same age Yuuken is right now"  Katsuki set a long wooden box on
"Then he offered to take care of my little princess whenever me and Yuki wanted to take time away."
Katsuki walked away from the box to look out the window as Kimi opened the box up

"So when me and Yuki left for a little date. We came back to find that Tengen was on a mission and he had accidentally dragged Y/n into it. Yes he saved Y/n with no injuries on her, but he was a mess and all bloody" Katsuki saw a little boy holding his mothers hand and walking happily.

"I then realized I couldn't let my daughter be caught up in the demon slayer corps. But I can't keep her away from that" Katsuki leand his head on the frame of the window.

"So you decide to just let her forge swords for Demon Slayers. Like you"
Kimi finished up his sentence.
The two heard Y/n's necklace jingling getting louder the closer she got.
Soon Y/n opened the door and had two drinks with her.

"Thanks for the drinks kiddo" Kimi thanked. Y/n gave her father a drink and stood by him as she watched Kimi grave her sword.

Y/n's eyes widen as she saw the blade turn into pure white. So white that it glowed. Like fresh snow.
"Pretty" Y/n whispers

-

For the first few days. Y/n was able to meet other people who were like her father, people who made swords for the demon slayers.

There was one man named Hatoru Haganezuka. He had a funny looking mask on him and scolded Katsuki for not having a mask and not having Y/n wear one as well.

"This is absolutely unacceptable! Luckily I have extras, take this little one and make sure to wear it at all times during business!" Hatoru gave Y/n the same mask he had on, but smaller.

Y/n nods with determination and put it on.
"Atta girl!" Hatoru praised Y/n.

Katsuki rolled his eyes
'Ridiculous'
