____________________________________

Mitsuki and Masaru talked with you the whole ride to the house.

"I wonder how Katsuki will react, we didn't really tell him about this." Masaru said worryingly.

When you were at the door Mitsuki suddenly stopped.
"I must tell you, you have an older brother and he's... er... different... and he says his own words so uhh.... a ... If he says something mean, he doesn't mean it, but he'll warm up to you soon!..... I hope..." She muttered the last part. And with that.

"Katsuki get down here please!" Mitsuki said, loud enough for Katsuki to hear.

"WHAT!?!" Came a muffled voice from upstairs.
"Hold on a second sweetie, I'll be back." Mitsuki said in a sweet tone. Then walked up stares, entering a room she slammed the door.
You could hear shouts and explosions from the room, it made you tilt your head to the side, pure innocence in her eyes.
"What are they doing?" The girl asked.

'oh God, now I feel bad for bringing her home' Masaru thought.

"A-ah its ok, th-this happens Alot." He answered.

Then the door suddenly swung open.

"Come over here right now!"

"What the fuck-!" He cut himself off when you came in sight. "WHAT THE FUCK IS THAT" He screamed and pointed to you.

Mitsuki gasped at Katsuki's language.

"LANGUAGE, KATSUKI!" She shouted.

"Shishishi, my name is Y/N! You can call me N/N!" You said with a grin, Ignoring the insult.

"WHY IS THIS EXTRA IN MY HOUSE!?"

"WELL GET USE TO IT CAUSE FROM NOW ON, SHES YOUR LITTLE SISTER!"
....
...
..
.

"WHAT THE FUCK!?"

BONK!

"OW!"

"LANGUAGE, KATSUKI!"

Masaru tried to calm the argument between the son and mother.

You just stared at the scene before you, dumbfounded.

Mitsuki cleared her throat.
"Anyways, Y/N, this is your big brother Katsuki, he's fourteen.
Katsuki, this is your little sister
Y/N, she's 4." Mistuki introduced calmly.

"It's nice to meet you, Nii-chan!"

"OH HELL NO, DONT CALL ME THAT!" He yelled, then picked you up like a cat, put you in a random room and slammed the door shut.
"FUCK OFF BRAT!"

You could hear muffled shouts and screams, followed by a loud crash.

After a few minutes Masaru opened the door to the room, and picked me up gentlely and carried me to Katsuki.

"Katsuki me and your Mother are going to prepare her room, please watch her till we are finished." Masaru reluctantly put you in Katsuki's arms and went up the stairs with Mitsuki.

"OI! I DONT WANNA HOLD THIS FUCKING BRAT!"

"KATSUKI I TOLD YOU TO STOP FUCKING CUSSING YOUR BEING A BAD INFLUENCE ON YOUR LITTLE SISTER!" Mitsuki shouted.

"Whatever!" He grumbled.

"Oh and if I see one fucking scratch, bruise, burn, or broken bone, your fuckin dead you hear me!?" Mitsuki shouted again.

"Bad influence my ass." Katsuki said through gritted teeth.

He then carried you like a sack of potatoes, with you over his shoulder and his hand on your back.
When Katsuki reached the top of the stairs he violently opened the door and slammed it shut.

He threw you on the bed like it was nothing, then said, "stay."

You pouted, "I'm not a dog."
"Well I consider you one." He shot back annoyed.

"Well that means you like me! Nobody hates puppies their so cute!"

"Shut it, I'm trying to study!"

...

...
...

It was silent for a moment, all you could hear was him flipping through the pages and the pencil scratching on the paper, until he heard soft snores, he stopped for a moment and looked at the sleeping form of his new sister. A small smile appeared on his face and he thought.

'cute'
...
..
.
'wait .....'

"WHAT THE FUCK!?"
' She's only going to get in your way, no way am I going to let an extra block me from my goal,  she's just a random brat the old hag picked up because, I don't even know why. She is no use to me.' He thought as he went back to studying.

Surprisingly the young girl didn't wake up by the loud scream her older brother made.
He could hear a faint 'LANGUAGE!' from across the hall where his parents were.

After a while it was dinner time and you already woke up.
You and your new big brother were walking down the steps when you suddenly stopped.

"Nii-chan, carry me!"

His head snapped towards you with an angry face.
"FUCK NO!"

"Pweeeeaaaseeeee" you said with puppy dog eyes.
His angry look disapeared into a panicked look, ' damnit why does she do this!' he thought.
At this point he couldn't resist.
"FINE! Just this once!"

"YAY!" you shouted in victory, the big brother grumbled somthing under his breath and bent down.
You claimed on his back and he carried you to the kitchen, as soon as he entered, Mitsukis head snapped towards him.

Mitsuki, who was holding a glass of water, dropped the glass she was holding.
Katsuki was wondering why she was acting that way until he remembered that a certain little girl was on his back.

He quickly took you off his back and set you on a chair,

"Katsuki..." He heard a voice behind him.

He turned around to see his mother with her hand on her mouth, she suddenly burst out laughing. "Hahaha, Katsuki is a huge softie!"

"SHUT THE FUCK UP! OLD HAG!"

"LANGUAGE KATSUKI!"

"Whatever" he mumbled. Then walked to his seat.
Masaru walked in and took his seat, then the family started eating.

After they all are Katsuki was about to leave when Mitsuki spoke up.

"Oh and Katsuki!" Mitsuki pulled out a piece of paper. No not a piece of paper, a looooooong roll of paper.

"Here's your daily chores!"
