Katsuki POV

Who was Deku think that he was trying to save me like I needed him to save me in the first place? I scoffed when I made it to my house I sighed and pushed the gate open and walked into the driveway there was a red bike in the driveway who could that have belonged to. I sighed and walked into the house I snarled I was getting worse the more that I thought about it. "Whoever you come out now before I have to hurt you.I'm in no mood and I am feeling murderous" I looked at the hallways leading to the different parts of the house but the sound came from the stairs. When I turned to see that he was walking down this huge smile on his face. "I'm gone for a year and you think that you can take bother really did you forget who I am?" He chuckled and I smile wide "Aiden you back what the hell. Do mom and dad know that you are are the old hag and the old man" He laughed and walked over to me pulling me into a hug and I managed to get a good look at him. He seemed different somehow like something or someone changes him. He was tanner than he was before, he had bulging muscles like they were guns but not so much so that they seemed too large and he got taller. I smiled and looked at him his red eyes more alert than before. He was usually really lazy everything came so easy to him so he didn't even need to try. I smiled at him and he walked to the kitchen jumping up on the countertop looking at me as I walked into the kind and put my bag on the kitchen table and rested my head for a moment. I could feel his eyes staring daggers at me. "What?" I didn't look up but I could feel him staring. "Nothing" He sighed and look at me before clicking the button on the counter top and the tv turned on. "So you going to tell the rents about this when they get back." I looked at him and then a tv to where I was taken over by the sludge monster.I punched the table setting it on fire. He rolled his eyes at me and laughed. I smiled and shook my head. "I can't even think about it without wanting to kill someone.I mean that quirkless loser thought that he could save me you remember Deku" I watched him smile at me and nod his head before turning it off the tv and jumping off the counter before grabbing a bottle of soda out of the fridge and drinking it. He still drinks soda like its water"So when did you get in?" I could tell that my question caught him off guard. "We aren't talking about me we are talking about you. How have been little brother? You need to start training for those entrance exams right." I looked at him and nodded my head "Yup I got a couple of months until the entrance exams I got to hit the books and then hit the weights. But now back to my favorite big bother" He snarled at me and sighed "Uncle Shiro picked me up from the airport. I grabbed my bike and that was all she wrote.I saw the rent on their way to the airport and decided not to say anything we still aren't speaking terms and that is how I wanted to keep it."

I nodded my head my mother, and her brother came from a powerful quirk family but she didn't similar quirks thank god I did. I turned to look at my brother he had one of the craziest powerful quirks which are also a byproduct of our mother side of the family. "So you want to talk about it." I looked at him he was looking a the ground trying to ignore my gaze. "Since when did, you have such a level head." I looked at him and shrugged my shoulder he seemed a bit but sighed, however. "It was fine I guess I mean in reality it wasn't as bad as people thought it would be but I don't know I guess I'm going to miss it in a way." He smiles at him but sighed heavily "If I tell you something about what I was doing there I need you to keep it to yourself." I looked at him confused but I nodded my head "It's not a military school I mean it is but you are only in the school for 2 weeks. It's s quirk battle regiment. We were separated into units that they would think we were studied in. I have been fighting in wars toppling governments. Coming back here seems lame compared to that. Last year he got into a big blow out fight that destroyed half the city. The mayor gave our mother a choice send him to military school overseas or go to jail. That wouldn't even be possible if it wasn't for who our mother's side of the family. "What unit were you in?" My question caught him off guard again was he so deep in thought. "Assassination unit I was the captain I'm pretty awesome." My breath got caught in my throat and Aiden smiled. I shook my head staring at him shocked. "I met a girl there she was there for the same reason that I was there. Her city gave her a choice go to military and or jail. Though with her powers there really isn't a place that they could hold her." He smiled lightly I could tell that he was trying to change the subject. "So what are you going to do now." He shrugged his shoulder. "I miss the familiarity it even now it's hard to believe but I got to use my quirk as much as I like but here I'm a prisoner. Mom and uncle Shiro got the government to let me ino UA even without the entrance don't know about my quirks full power so it should be interesting that is for sure. I can't wait to see there face when they figure it being said I am going to my room before the rents come home and ruin my life even more than they already did."He ran his hand through his buzz cut, I cocked my head to the side. "What do you mean." He looked at me and smiled sadly "I wanted to stay in the military in Greece but they insisted that I come home and since they have rights over me till I'm 18 I don't really have a choice. See you in the morning."

He waved over his shoulder before waking up the stairs his posture was different he used to slouch but he carried himself differently. I shook my head and grabbed some pizza out of the fridge and microwave it.I watched the pizza turn in a circular motion when my parents came home. My mother was yelling about that stupid bike in the driveway. She walked into the kitchen and looks at me "What the hell was you doing trying to fight a villain." I rolled my eyes and glared at her the bitch did it look like I was having fun. "Watch it you old hag I didn't fight them, I was taken hostage by them." I looked at her and growled before grabbing my plate out of the microwave and sat at the table eating my pizza. Before looking at them and sighed. "Aiden's upstare. Uncle Shiro picked him up, the bike in the driveway is clue how he got it either so don't ask and he is not in a mood to talk. In fact, he is pretty pist." I looked at them and come to chew on my gooey pepperoni's pizza. I slurped up the cheese and licking my fingers before putting down the pizza and grabbing a bottle of water and sat back down I watched them watch me for a couple of minutes before folding my arms. "He talked to you." I growled at her and nodded my head "Did he not talk to the two of you.I know that he called the house plenty of times or at least called me." I looked at her and she stomped her foot into the ground. "That brat we had gone to the airport to get him and he had the nerve to get picked up and not tell us. I am going to give him and Shiro a piece of my mind." She snarled angrily and yelled the whole time she was giving me a headache. "Will you shut up you old hag." I snarled at her and she laughed at me her hands on the table and laughed at me. "You want to go sludge boy." I snarled at mother "Bring it." "Would the both of you calm down." I turn to look at my father my anger only rising "Shut up." I glared at him and turned back to yell at my mother. It went on like that for an hour before I heard movement on the steps.

When my mother turns around there he was his red eyes glaring at the out of us dangerously. "I'm trying to sleep this jet lag is kicking my ass so if the both of you could shut the hell up. Then that would be greatly apprenticed." He looked at me and I sighed and nodded my head sitting back down in my chair sighed rest my arm over my eyes for a moment. "You have gotten so tall in the past years and god you are so tan." I moved my arm off of my head in time to see him roll his eyes and looked at dad this anger flaring in his eyes especially when he looked at her. "I'm going back to bed if you would keep it down like I said it would be greatly appreciated." He was turning around about to walk to his when mom stopped him. "Wait why didn't you tell me your plane landed early." I watched him turn around this killer look in his eyes that lit up his face. "I didn't want to come home and I don't want to have to look at the two of you. Greece was where I belonged, there stupid deal with the quicker users from Greece worked out in my favor I found something I was good at and then I was forced to come back here. My life was there I had nothing for me here except Katsuki and he could always visit me." He snarled and walked back up to the stair and mom collapsed on the floor. She looked like she was going to cry. I sighed and walked up the stairs and was about to walk into my room when I decide to take a detour. I open the door to see that Aiden wasn't sleeping at all has talked to someone on the terrorist. I sighed and walked out and look at him. "What if you damage? You made the toughest women in the world cry." I looked at him and he sighed heavily. "I can't talk Akane my little brother wants something." I saw him smile to himself. "Yeah, I'll see you then."

I watched him hang up the phone before looking at me and sighed "If she cries that was because her resolve is weakening. She made a life-altering decision for me, one that I didn't want all because she thought that it was what a best. Only it turns out that she was wrong and I enjoyed my life there. She didn't cry because of me. She is crying because for once in her life she might have to admit that she was wrong." I looked at him and he is sighed "I love you which is why I'm not yelling at you for bringing any of this just know that I don't care maybe I will down the road when I get into the swing of civilian life but until then I am heading to bed. I will see you in the morning baby brother." He pushed me out of the room and into the hallway.I stood there stunned I don't really know what to say. This was all so weird. I walked into my room and close the door.
