Work Text:

Katsuki came home from UA for the weekend. When he walks in his mom is on the phone. The second Mitsuki turned to him saying one last thing on the phone before hanging up katsuki knew who she was on the phone with. Aizawa. Anger flashed in Mitsuki's eyes and katsuki took a step back. He couldn't go far as he felt the door press against his back. He tried to reach the door knob but it was to late, his mother was already standing infront of him.
"Katsuki. Why is your teacher calling me AGAIN about you lashing out and yelling! You know the consequences. Why can you just be like izuku!" Mitsuki yelled at katsuki raising her fist to hit him. Bakugou flinched bracing for the impact of her fist on his chest. The impact was hard, he found himself slightly gasping for air but Mitsuki didn't stop. She landed about ten more hits on him, and slap across the face and punches to the chest and stomach. "You little brat! You just have to make me look bad all the time don't you!" She yelled grabbing him by the ear.
"Im sorry mom just please stop!" Katsuki said still slightly gasping for air. Mitsuki let him go and turned her back to him.
"Your weak katsuki. Just like your father." She said before walking into the kitchen. Katsuki stood there for a moment before walking quietly to his room and gently shutting the door. He sat on his childhood bed, his mother never bothered to redecorate it so it was still a room belonging to a small boy. The bed was small, the covers had all might on them, a few all might posters on the walls. A shelf with stuffed animals above his bed. A newer addition to the room was a big circle rug covering most of the floor. Katsuki knew why it was there but he lifted it up anyways. Under where the rug sat was burned floor boards. Katsuki remembered the nights he woke up from nightmares as a child, not able to control his quirk, his mom not caring. The burns look worse then he remembered, thats when the memory of the last time he actually came home over the weekend and remembered that it looked worse then he thought because it was. Some of the burns were new from the last time he was here. He woke up from a nightmare he constantly got over and over from being kidnapped. He was having a panic attack accidentally burning the floor with explosions in the process. He tired to get out of his room that night, leave the house but his mother never stop the punishment she gave him as a kid to keep him from waking her up. He tried to leave but his bedroom door was locked just like it used to be every night. His mother used to lock him in his room at night because as a little kid he would wake her up when he got scared. He said it was to train him not to be weak.

--------------------------------
After about 45 minutes of looking under the new rug he finally came back from spacing out. He put the rug back down and ran his fingers through his hair. Suddenly his mom burst in the room. She looked at him angrily.
"I called you for dinner ten minutes ago! I don't know what you do at the dorms but here you should know to listen!" She yelled and katsuki realized he probably didnt hear her while spacing out.
"Im not hungry mom." He said quietly.
"I don't care if your not hungry! I made food for you so come eat it!" She shouted back. Katsuki nodded and matsuki turned to leave with katsuki following. He followed his mother into the kitchen to see his father sitting at the table. Masaru was quietly eating the food his wife served him. He had a small bruise above his eyebrow. Katsuki sat next to him and his mother handed him a plate as she sat down aswell. His father and him made small talk katsuki not touching his food. Matsuki noticed and smacked the boy on the back of the head.
"Eat your food brat! I went through all the trouble to make it so eat it." Matsuki said firmly. Katsuki did as told eating his food even though all he could think about we throwing up. He made it through dinner and went to his room again closing the door behind him. Luckily his room had a joining bathroom just to himself because katsuki felt sick. He rushed to the bathroom closing the door behind him. He hunched over the toilet feeling sick to his stomach. It's easy to get away with not eating at UA because he typically makes his own food, but here he can't. His body has started to feel sick after he eats any food because it just so used to throwing up. But katsuki didn't care, it was like he was addicted to seeing the numbers on the scale go down. As a child his mother always commented on his weight even going as far as starving him because she thought he was fat. He wasn't. But now that mindset is carved into him. He gags and throws up in the toilet. He still dosent feel empty enough. He sticks his fingers down his throat until he feels like he never ate. Of course his mother didn't pay any attention or didn't hear him.

--------------------------------
Katsuki spent his Saturday staying in his room. His mother burst in his room at dinner time glaring at him. His back was faced to her
"Katsuki! Come eat." She said firmly. When katsuki didn't answer she noticed his hearing aids on his nightstand. He grabbed his shoulder hard and turned him around harshly. He looked at her confused. She grabbed his hearing aids and threw them at him. He quickly put them in and matsuki stood him up.
"Just because you need hearing aids dosent mean you can disrespect me katsuki! Fine! No dinner for you." She yelled at a very confused katsuki. She slapped his across the face and landed a firm punch to his ribs. He fell to the ground clutching his ribs as she repeatedly kicked him in the stomach. She turned around and left slamming his door behind her. Katsuki eventually stood up and found his way to his bathroom. He closed the door and stood infront of the mirror. He lifted up his shirt, his stomach and chest covered in dark bruises, the worst ones across his ribs. He felt tears well up in his eyes as he slumped down against the counter. He sat on the floor pulling his knees to his chest trying to calm his quickening breathing. He felt fear and sadness fill his chest. He opened the top drawer under the sink and reached under the hand towels where he hid his pocket knife. He grabbed the knife and opened it. He slid his sweatpants down. His thighs were covered in scars from cutting himself. His slid the knife on a clear area of skin pushing down gently. Blood beaded up in the cut. Katsuki calmed a little at the sight of blood but he didn't cut deep enough. There wasn't enough blood. He started adding deep cuts, blood dripped down into the tile under him. He heard his mom come into his room and he quickly flushed to toilet to make it seem like he was just using the bathroom. He closed the knife and put it back in its hiding spot. He quickly grabbed medical tape and gauze and quickly patched himself up wiping the blood off the floor in the process. He stood up, pulling his sweatpants up in the process and washed his hand wiping his tears and taking a few deep breaths before opening the bathroom door and walking back into his bedroom where his mom stood, arms crossed. His mom glared.
"Katsuki. Go take out the trash then go back to U.A. you've been here long enough already." She said firmly. Katsuki nodded and went to take out the trash as instructed.

------------------------------
Katsuki grabbed his bag putting the few things that got taken out back in. He left his room and made his way to the door putting on his shoes when he heard footsteps behind him. His body involuntary tensed as he guess it was his mom to give him one last beating.
"Are you going back to U.A katsuki?" His father masaru said behind him. Katsuki relaxed and turn.
"Ya dad, I am" katsuki said calmly. "Sorry im leaving so soon, I would stay longer so you could have a break from new bruises..." He said softly. Masaru walked closer placing his hands on katuskis sholders,
"That's not your job katsuki. I much rather me then you. She really does love you...she just....has a bad temper..." masaru said trying to calm katsuki down.
"That dosent change anything." Katsuki protested "I-" he was cut off but masaru being pulled back and his mother standing infront of him.
"Listen here you little brat. Don't act like you don't have a temper too! Your father is fine! He dosent need someone who's weak like you to try and protect him!" She yells slapping him hard across that face, her ring cutting his cheek somewhat deep. Katsuki grabbed his cheek and backed up. Matsuki opened the front door shoving him hard out. He landed on his back on the doorstep looking at his mother still inside looking at him like he was trash. Matsuki threw his backpack at him and slammed the door locking it. His backpack landed with a thud on his stomach. He stood up putting his bag on his back. He walked to the train station like usual. When his train got there he sat quietly putting on headphones listening to music and leaning against the window.
-------------------------------
When katsuki arrived at the dorms he was lucky that because it was already mostly dark no one was in the common room. He quickly walked to his dorm closing the door behind him. He threw his bag on his desk chair and sat on his bed, his back against the wall, burying his head between his knees. He sat like that for a bit before he picked his head up to check his phone. No new messages. He felt tears well up in his eyes. He stood up and went to his bathroom. He look through his cabinet under the sink, he grabbed a bottle of pills and walked back to by his bed. He sat on the floor his back against his bed, he looked at the pills and decided he needed to cut more first. He grabbed his knife he kept in his nightstand and fully took off his sweatpants. He ripped off his make shift bandages and started cutting again. Blood pooled on the floor around him as he couldn't stop himself from cutting again and again, deeper each time. He eventually stopped himself finally feeling the pain. He dropped the knife and gripped his hair he let out a frustrated scream with he instantly regretted because he heard a knock on his bedroom door.
"Bakubro?" Katsuki heard kirishima say through the door. Katsuki didn't answer hoping he would just go away and after a few minutes he did. Katsuki knew it was now or never so he opened the pill bottle and swallowed about 7 or 8 pills. He started the feel like he was going to pass out and his breathing slowed. His arms dropping beside him as he closed his eyes. He could barely hear it but there was another knock on the door. This one more firm. This wasn't kirishima, katsuki knew that much but he still didn't know who it was. They knocked again before finally speaking.
"Bakugou? Are you alright?" Aizawa. It was aizawa. Katsuki knew if he didn't answer aizawa would come in but when he tried to speak nothing came out. His door gently opened. Next thing he knew aizawa as kneeling infront of him shaking him.
"Katsuki!" He said frantically. Katsuki opened his eyes and looked at aizawa, fear was in his eyes and he frantically tried to get him to stay awake. "Kid come on stay with me!" He said still shaking him.
"Mr. Aizawa?" Katsuki said weakly.
"Yes katsuki, its me. Come on stay awake. We're going to the hospital." Aizawa picked him up gently pulling katsukis arm so they weren't hanging down. Katsuki closed his eyes again.
--------------------------------
Katsuki woke in a hospital room. His eyes squinting to adjust to the light. He quickly realized he wasn't alone as he heard someone breathing next to him. He looked over at the chair next to his bed, aizawa was sitting there resting his arms on his knees his head dropped clearly not aware to katsuki being awake.
"M-mr. Aizawa...?" Bakugou said quiet enough that aizawa barely heard it but he looked up making eye contact with katsuki.
"Katsuki. Your awake.." aizawa said softly with worry in his voice. Katsuki nodded and looked around the room. "What the he'll were you thinking katsuki!" Aizawa said firmly but softer then usual.
"I-....i-i don't know..." katsuki cursed himself in his head for shuddering. He looked through the window looking into the hospital and saw his parents talking to a docter. Fear flashed in his eye and aizawa definitely saw it, following his line of sight and realized he was definitely missing something.
"Katsuki. What's wrong?" He questioned. Katsuki didn't answer, he just stared at his parents through the window. He made eye contact with his mom who just glared and turned away. Katsuki looked down.
-------------------------------
At some point katsuki must off fallen asleep because he awoke to the door to his room closing. He opened his eyes, aizawa was no longer next to him or in the room at all. Instead his mom was standing on the other side of his bed.
"What the fuck is wrong with you katsuki!" His mother whisper yelled at him. "You take every chance you can to make me look bad! You selfish brat!" Her voice raising slightly. Katsuki looked out the window again and saw aizawa approaching his room oblivious to what his mother was yelling at him. "Your so weak! Instead of being a man you just try to kill yourself!?" She says a little to loud as bakugou locks eyes with aizawa through the window who is now right outside the door and clearly heard what she said. Matsuki lands a slap on katsuki right as aizawa swings the door open roughly.
"What the fuck do you think your doing Ms. Bakugou!?" Aizawa yells roughly, the earlier softness in his voice replaced with pure rage. Mitsuki turns around planning to plead her case but aizawa dosent stop. "Do you really have an excuse for abusing you son!? Physically and mentally. Katsuki shouldn't have to apologize for what happened! And by the looks of it you don't even care about how he is even though he almost died! you just care about how your image is!" Aizawa yells at the woman. Mitsuki scoffs,
"You can't talk to me like that. I don't want you as his teacher, im going to take him out of your class you annoying old man!" She yells and katsuki looks at her shocked.
"No mom please don't!" He says pleading.
"Shut up you brat!" Mitsuki snaps back. Aizawa decided he's heard enough.
"That's enough. Get out Ms. Bakugou." Aizawa says annoyed but calmly. Misuki scoffs again,
"No. This is my child and I will not be leaving. You will." She says firmly.
"No. You will. When you signed the forms for katsuki to stay in the dorms you agreed that if the school felt a child was not safe at home then the school would take over custody of the child until a permanent place is found for them. So no. I will not leave as he is now in my custody. You will leave." Aizawa said calmly his voice raised by the end of the sentence. Mitsuki looks shocked before leaving quietly with a look at anger on her face. The door closes behind her and katsuki watches her walk to his father. After matsuki talked to him for a minute masaru makes eye contact with katsuki through the window a look of happiness but also dread on his face. Aizawa walks next to katsukis bed gently placing a hand on his shoulder.
"Katsuki, why didn't you tell me or anyone about her abuse?" Aizawa said calmly. Katsuki just shrugged
"I couldn't..." He said not looking at aizawa.
"Why not katsuki?" Aizawa said now crouching next to katsukis bed so he could see his face. Katsuki thought about saying to protect his father but he knew his dad wouldn't leave his mother even with the abuse so it was no use.
"I was scared..." He said quietly, it wasn't a lie but not fully the truth. Aizawa nodded and pulled the kid into a hug. Bakugou tensed but after a few seconds he relaxed and tightened his arms around his teacher. He felt tears welling up in his eyes and he tried to stop them but he couldn't. He broke down crying in his teacher's arms, trying to calm down he attempt to pull away but aizawa didn't let him.
"Your okay katsuki. Your safe. Just let it out." Aizawa said, his voice soothing. Katsuki relaxed again not able to stop his tears.
-----------------------------
Katsuki didn't know how much time had passed but it must off been a while because his eyes were dry, all out of tears. He was still clung to his teacher who was rubbing his back. Aizawa pushed away grabbing katsukis sholders and looking at his face.
"You feeling better?" Aizawa asked quietly. Katsuki just nodded not look at aizawa. "The doctors said you have to stay overnight but then you can be discharged." Aizawa explained getting only a nod in return from katsuki. "Okay kiddo, get some sleep." Aizawa said sitting back in his chair. Katsuki layed down and pulled the covers over himself.
-------------------------------
When katsuki awoke aizawa was putting the clothes he came in with in a bag. Aizawa turned to katsuki seeing he was awake and sat in the chair.
"How are you feeling kiddo?" He asked softly. Katsuki sat up before answering,
"I feel alright..." He said quietly. Aizawa nodded.
"The docter said your free to go so just get changed and we can go." Aizawa said holding out some clothes. Katsuki looked down at the clothes and took them hesitantly. "They might be a bit big. They are just some of my sweatpants and a long sleeve shirt. Yamada brought them for you from our home." Aizawa explained. Katsuki nodded and went into the bathroom getting changed. The sweatpants were a little to long and bunched up at his ankles but they fit around the waist fine. The shirt was quite big but that was due to how unhealthy thin katsuki was. He walked back to the hospital room where aizawa was standing waiting for him. Katsuki quietly follow aizawa out of the hospital and to his car. Aizawa opened the passenger door for katsuki and he climbed in sitting quietly. Aizawa got in the driver's seat and started driving. Bakugou looked over hesitantly wanting to ask a question but not sure if he should. Aizawa noticed and looked over,
"Ask me whatever is on your mind. Im sure you have some questions." Katsuki nodded hesitantly.
"Whats gonna happen to me? Where will I go?" He said softly quiet aizawa almost didn't hear. Aizawa smiled pulling up to a house.
"Your going to stay with me and hizashi. I talked to him last night and because eri and hitoshi share a room we have a spare. Your free to stay as long as you want." Aizawa said with a small smile. He got out of the car grabbing a bag from the back seat and opening the door for katsuki. Katsuki hesitantly got out of the car.
"Are you sure mr. Aizawa? I don't want to be trouble.." katsuki said quietly. Aizawa placed a hand on his shoulder.
"I am one hundred percent sure katsuki. It's not any trouble. I want you to be in a safe place and I promise our house is as safe as it can be. Also in my house you dont need to use formalities. Just call me and hizashi either our last or first names. No mr." Aizawa said calming katsuki down convincing him that it is ok. They walked together up to the house and aizawa opened the door stepping inside, setting the bag down and removing his shoes. Katsuki followed him removing his shoes aswell staying close to him and closing the door behind him.
"Dad!" Eri yelled running into aizawas arms hugging him. Aizawa chuckled picking her up.
"Hey eri, where's papa?" Aizawa said holding eri on his hip.
"He was helping hitoshi with something" eri said hugging her dad tighter. Eri the turned to katsuki and smiled. "Mister boom!" She said happily which made katsuki chuckle. Suddenly hizashi poked his head around the corner and smiled walk over. He hugged aizawa kissing his cheek gently before turning to katsuki.
"Hey little listener!" He said happily. Katsuki nodded in response.
-------------------------------
It was later that night, katsuki was sitting on the bed mic showed him to. He had 7 missed calls from his mother and 10 texts all basically just calling him weak and pathetic. His eyes welled up with tears. He pulled his knees up to his chest leaning against the wall behind his bed. He layed his head on his knees. As if on que aizawa gently knocked on the door that was already cracked open and slipped inside. He sat next to katsuki who was now crying into his knees. Aizawa looked at him with worry,
"Katsuki? What's wrong kiddo?" He said softly. Katsuki turn to him just sobbing and leaned his head on aizawas shoulder. Aizawa quickly wrapped his arms around katsuki pulling him closer, letting the kid just cry into his shoulder. Katsukis phone dinged and he turned to look at it. It was his mom calling him pathetic again. Aizawa was about to take his phone so he didn't have to look at it but katsuki picked his phone up and threw it across the room, it shattered as it hit the wall. He then clung back to aizawa who quickly realized thats why he was crying. Aizawa pulled katuski. Closer.
-------------------------------
Hizashi got home from patrol at about 1am. He took off his shoes and walked into his and shouta's room quickly realizing aizawa wasn't in their bed. Hizashi changed out of his hero costume and into black sweatpants and a white t-shirt. He walked out of his room trying to find aizawa. He checked the couch and the bathroom before finally checking the guest room. The door was slightly cracked open and there was a light from inside. He pushed the door open a little more and peaked his head in. The room was dimly lit by a lamp on the nightstand. Aizawa and katsuki were sitting on the bed, asleep, curled up together. Aizawas back was against the top headboard, katsuki curled up in his lap, his head on aizawas chest, aizawas arms wrapped around katsuki. Hizashi smiled softly and entered the room quietly. He turn off the lamp and layed on the other side of the bed making sure not to get to close to katsuki as he didn't have permission to touch him. He closed his eyes and fell asleep. All three slept peacefully without a care in the world.
