Katsuki glared at your small feared form he almost could barely look at your doe eyes, they held so much innocence and life. He almost broke in your tear filled gaze. But he couldn't, he would never show weakness, the same one he saw in your eyes. There were secrets that were kept too deep memory can't bring them out.

He turned away and walked on. He will not look back. He shouldn't.... He couldn't.... The last year of middle school is drawing near and soon high school. He must be a hero that is what he oath that is what he tried to put in the minds of everyone who meet him. And he caught himself becoming something he never wanted to be...

WEAK

During the time you've been in the house, you were the stubborn one who always try to get under his skin and weaken him. On his view, he wanted nothing to do with you, but you still reached out, maybe if he actually stopped being so obsessed with being the No. 1 hero he would have....

"No...."

Katsuki glared at the pavement road with a dark look. You never were supposed to be there, your appearance was never part of the plan, HIS plan, and now you have to deal with it.

"I will be a hero, all unnecessary things will never get in my way..."

"I will never let them.."

[Later]

The sun settled down the horizon as Katsuki left his after of relieving stress and toning down to his normal level of anger, just like then before you entered his damn important life. He let out a stressed sigh before walking on.

'Wait.. what time is it!? Damn it I gotta pick up--'

He halted his trek to your school and clenched his with anger. "That damn brat is manipulating me... That little shit can get themselves home! I don't care about that little shit anymore!" he grumbled and started walking home.

Passing the gates he drag his shoes to clean the dirt off then opened the door. Everything seemed to be normal until he passed the entrance of the living.

"Welcome home Katsuki.." Your mom glared at the boy on her seat on the arm chair that was coincidentally facing the entrance. He was surprised that she suspected him to be there  but didn't show as his eyes trailed to the two individuals in the room, aside from you their was two other that weren't familiar to him. A boy with grey hair and a woman with dark brown hair, bangs covering her eyes and dressed in a maid outfit.

"Who the fuck are they?" He asked harshly. The maid eyelessly glared at the blonde boy, who felt the gaze while Tora boredly looked at him.

"Oh I don't know, the one who brought your sister home.."

Sensing the sass in Tora's voice Katsuki was just as quick to get agitated as he was. "What the fuck did you say to me punk!?" he yelled.

"Katsuki! These are our guest! Behave!" Barked Mitsuki, mad at him about leaving you at school.

"They are your guest! I gave a fuck!" he yelled about to leave if it wasn't for Mitsuki who stood up. "Hold it! Where were you this after noon, you practically left your sister to herself! She's still a child!"

"Well she should have grown up by now!"

"(Y/N) is your sister--"

"She is not!" he yelled with fury silencing the room. "I never wanted to have a shitty sibling, I never planned to have one, this was all you! Your fucking idea!" He clenched his teeth finally loosing it. He was quite before just so that he won't get in trouble but now...

"The brat is your choice, I am not included with you ass-hats! You may have given her the last name and called her as your child, but she is never a sibling to be or is a family to me! I wish you never fuckin existed then my life would have so much freaking easier!!!!!!!" There was no more room for his steams. Red as a boiling pot he stomped up the stairs and a loud bang was heard as he shut the door.

Once he was gone you broke down in your seat between your mom and Tora. Tora was just as furious as your mom if she didn't hide it as she was trying to ease you, hugging you close to her telling you everything is fine. How she wish it was, she hoped that Katsuki was not so stubborn and just accepted you.

But she knew that it would have never been Katsuki if he gave up.

'Big brother.... your are really.... uncool......... I hate you...but I can't because you are my brother.... I'll try...'

You tried to oath yourself into understanding him, but you are a child... and you have much to learn, and you need to know when to just... give up.

=========================================

Oh gosh I did terrible.... I'm sorry! This was better in my head,  but know I just got confused on where am I... This is not the next chapter. This is an attachment to the previous chapter I failed to post. Though I am to spoil it is almost the time for reader to slowly gain their quirk. I will post some side stories of either her times at her school or any of the scenarios you would request(though seriously guys request pls?) and whoever gets it right first would either get a free request of oneshot, whatever it would be, and the chapter where the reader's quirk will appear dedicated to them.

Come on! I challenge you guys to guess, except for you Emo, I know you may have*coughImayhavetoldyoucough* found out.. Anyway have a good day!

Peace! X3
