chapter 5

Katsuki woke up Y/n early and they went on a jog. Katsuki was surprised at how fast the kid ran. She was able to keep up with him all the way. He was proud of her.
"Onii-san?" She called him as they were walking to school.
"Hmmm" he's replied.
"W-what if m-mama and p-papa wanna t-take me b-back?"she stuttered close to tears.
"Hey ,you ain't going nowhere. We adopted you. It's their damn faults for leaving you in the first place"katsuki told the girl. Y/n smiled and continue to walk with her big brother. She smiled all the way to school. When they arrive Eri and her sat watching the students train. She saw katsuki's quirk and began jumping up and down.
"Boom! Boom! Boom!" She yelled excitedly. Katsuki smirked at his little sisters actions. She stopped when she saw mineta coming towards her. She didn't like him. She quickly ran toward katsuki and was almost hit by todoroki's ice. Y/n simply shot fire out her hand instantly stopping the ice then continued to run to katsuki. Class 1-A was shocked at the little girl.
"Boom!" She said as she hugged her brothers leg. He looked down at her then bent to her height.
"Don't ever do that again! That was dangerous!" He scolded her. She looked down at her feet
"I'm sorry i just wanted to get away from mineta" she apologized. Bakugo sighed but kept the angry look on his face as he picked his sister up and took her out of the training area and back to the classroom. Soon everyone came back and things went on like normal. Bakugo and y/n were about to go home but bakugo had to go back because he forgot something. Y/n waited by the gate of the UA building for bakugo.

Y/n pov

I was waiting for onii-san because he forgot something when i heard the voice of someone i never wanted to hear again.
"Well well well if it isn't the mistake." I heard them say. I slowly looked towards them.
"M-mama p-papa?" I said with fear in my voice.mama looked at me in disgust. Papa put a hand on her shoulder.
"We are not parents to a mistake like you." Papa told me. Tears fell down my face. Papa went up to me and grabbed my arm.
"Let's get this over and done with quickly" mama said. Papa dragged me as people stared.i didn't like this at all. They took me to a dark alley and they raised a knife. My eyes widened and my quirk activated. Plants grew and wrap themselves around them as i ran. They managed to break free and we chasing me. I turned back at them and prepared to fight just like onii-san had taught me. I wouldn't go down without a fight.

Katsuki pov

It's been hours the hag and the old man rushed back home when i couldn't find y/n. I acted like i didn't care but i did. I was so worried about the little squirt. We had been busy looking for her for hours until the hag got a call and we immediately got in the car. We arrived at a hospital and my fear shot up but i hid it. I saw a male and a female put into a police car. The man went quietly but the woman was screaming.
"You mistake!!!! You were never meant to be born!!!" The woman screamed. I noticed that both of them looked a bit beat up. As we entered the hospital i saw a another woman being arrested.
"That's the woman Ashley" the hag told me. As they walked past Ashley whispered a sorry to us. A doctor come out and went towards us.
"Mister and mrs bakugo?" The doctor asked us.
"Yes that's is" the hag said.
"Miss bakugo i am aware that you adopted a child by the name of y/n am i correct?" The doctor said. The hag nodded.
"Well today your daughter was forcefully taken by her blood parents and they attempted to kill her. She put up quite a fight but was badly injured" the doctor told us. The kid was hurt!! I was beyond furious. I wanted to kill her asshole parents. I heard the sound of feet dragging on the floor and saw y/n making her way towards us.
"Y/N" i shouted and ran towards the squirt. I bent down Infront of her and hugged her gently so i wouldn't hurt her. She hugged me back.
"D-did i do g-good boom?" She asked me.
"You did excellent squirt. You kicked their asses and now their going to jail for a very long time." I told her. She relaxed in my arms. I picked her up and took her to the hospital room she was in before.she fell asleep in my arms the fight must have been intense. I wish i had been there to protect her.
