Katsuki's New Sibling Life (boku no hero academia x child reader)

Chapter 31: Mean Brother!

Once again silence has grace the Bakugo residence as the summer continnued to roll on like a peaceful wind.... It was completely boring.

And it seemed that right after your graduation, your friends somehow all had something to do during month long event but not your family. All because Katsuki is preparing for his entrance exam, but you couldn't blame him that much, he did tell you it was a really 'big deal school'. Though that was how many days ago and you are bored as hell.

There is nothing to do and the only thing she can do was train with Izuku but soon All Might told you he had to focus on Izuku because his exam was coming close, so that was also a bust.

Sitting upside down on the couch watching seemlessly any channel you are allowed to watch. The blank face on your face held a warning sign to anyone who dare to approach, your father was a victim to your newly developed creepy stare...

As if you were the only one in the room you groaned loudly shuffling constantly annoying the only other blonde you actually bothered staying near you.

"Stop moving you dumb brat!" He hissed pushing you off the couch to lay on it entirely. "Hey!" You whine lazily hitting him "Why aren't you training now!?"

"I am taking a break." Katsuki mumbled taking a sip of his water bottle.

"You are lying! You just don't wanna play with me!" You puff your cheeks stubbornly in which Katsuki gave a thoughtful hum.

"Yeah, you're right, I just don''t want to be bothered by you idiot."

You blinked at the male's straight forwardness but soon burst into tears. "WAAAAH!!!! BIG BROTHER IS SO MEAN!" You wailed causing  the male to groan loudly. Picking you up by the shirt Katsuki marched to your room and dumped you on your bed bfore leaving.

"You. Stay." He ordered.

You merely stuck your tongue out to him. "I am not a dog, you can't make me!"

"You will have steak tonight."

"I am a good girl!"

[--]

You yawned as you woke up from your light slumber, looking over to the clock you noticed it was pretty late.

You scratchhed your head when you saw it. 'I don't usually wake up this early...' You pondered to yourself.

Just as you decided to try and sleep you heard a soft sound downstairs which stole your curiosity entirely. 'Hmm...' Hopping off your bed you made your way to the stairs and took a peak around the corner.

But you couldn't see anyone downstairs which was odd since you were told, if there is a noise, there is a source. And so, you had heard a noise but there is no possible source of it in sight!

Now this was riling up your curiosity to the max and everybody knows not to get you too curious.

As your eyes scan around the dark room, you were only barely able to see the front door shift close. You felt a shiver down your spine as your remember one of Kōyō's haunted stories.

'Ghost are real!?' You gulped loudly before nervously making your way to the front door. With shakey hands you carefully reached for the knob but instead the door flew open.

Thunder clashed as a tall figure loomed over you it groaned lowly as it move towards you. Before you could process your actions your mouth opened and a scream erupted from your throat.

"Sssh! Goddammit!" Katsuki hissed covering your mouth dripping wet from the rain that has been falling since hours earlier.

"H-Huh? B-Big bro? W-Wha? But the monster and ..." You stuttered still in a daze of shock and confusion pointing in all sorts of direction.
