Chapter Text
Katsuki moved quietly towards the door as Izuku laid Hisashi’s body down.
“It could be our help...” Izuku said keeping his voice low so that whoever as on the other side of the door couldn’t hear.
Katsuki glared over at the green haired teen before he grabbed the door to yank it open. Bright red eyes glared at the person in the hallway a step or so back from the door with their leg raised like they were about to kick the door in. And upon looking at the persons face he was 100% sure that was the intention behind the action.
“You guys needed help with something?” Fucking Dabi said after an awkward moment as he lowered his leg back down looking at him with a questioning look.
“You called the Burnt Fucker?!” He yelled behind him glaring over at his boyfriend.
“Well, who else was I going to call Kacchan?” The other teen said back voiced raised slightly as he moved to be in view of their apparent help / guest in the hallway. “Shouto said to message Dabi if we needed any help like this. It’s not like I could call Sensei!”
“Considering it is Eraser Head I’m sure whatever this is he would help as well. He’s just as crazy as you lot.” Dabi said interrupting Katsuki’s next word throwing and getting both of the teen's attentions back to Class 1-A honorary Big Brother. “Now WHY was my date night interrupted? I don’t get much time with him you know so let's get this over with.” The probably still a villain sounded only slightly put out but even Katsuki was sure it was more of an act than actually being mad.
“Oh, ummmmm come in come in.... I... Well, we... uhhhh Kacchan?” Izuku floundered for an answer in the face of someone he himself had called for help from.
Katsuki rolled his eyes as he moved out of the way to let the villain into the apartment quickly getting the door shut as soon as Dabi was clear and moved past him to be next to the nerd. “Deku’s shitty sperm donor hit Auntie.” The blond spat angerly still pissed at how someone could ever think of doing such a thing to someone they were supposed to love. And if what icy-hot had told them before about his dad than he is sure the man behind them would understand their reasoning's for what they did. “And well... Noone. Noone hurts Auntie. He also tried to hurt Deku before choking me... So yeah, now we have to get rid of the thing.”
Dabi stops when he sees Izuku’s father on the floor of the living room by the couch. The villain didn’t even look at them as he moved around to look closer at the man. Katsuki watched as prodded his steel toed boot into the piece of shit’s side. The body shifted with the motion but nothing else which was good because Katsuki isn’t sure how he would react if the fucker was still alive somehow. “Well while I do think your teacher would have helped you with this it is better that you called me instead.” He looked at the Izuku as the teen moved beside him hands twisting together in a nervous gesture Katsuki knew was more out of fear for being in trouble. The probably not really a villain at this point gave a soft smile and reached to ruffle his green hair gently. “You did good kid.”
The blond watched how his boyfriend relaxed at the words and the gentle hand in his hair. “Right so let's get this into the bathroom. Most places nowadays are made of porcelain or treated with fire resistant materials so it can withstand the heat of my quirk long enough to take care of this and it will make for an easier clean up as well. Ash is not fun to get out of carpet nor is it easy to replace if I scorch it.”
Katsuki nodded as the instructions made sense to him about the bathroom being the best place to take care of the body. It wasn’t like they could drag it out of the apartment to the roof or alley. “Deku go disable the smoke alarms so that they don’t go off. I’ll help Asshole here.” He addresses the other teen before crouching down to get a good grip on the body to heft it up. “Alright Bacon Bits this way.” he said looking at Dabi before leading the way to the bathroom.
He heard Dabi give a soft laugh as he followed. “It’s funny you call me that because Crusty does as well when he’s annoyed with me which seems to be a lot of time now.” Katsuki only grunted in answer and stopped at the door to the bathroom waiting for Dabi to open the door before going in. He unceremoniously tossed the body of the asshole onto the floor as the other looked at the tiles all over the floor and walls rapping a knuckle of them quickly. “Yeah, this should be good enough. Right so get out. It is about to become a furnace in here and your quirk is not going to be a good mix.”
The frowned looking at Dabi half skeptically but still nodded. “I’m going to help the nerd clean up the mess this piece of shit made.” He said before turning sharply to leave the bathroom. Dabi only gave him a hum in acknowledgment as he shut the door. Deku was in the hallways trying to peer around Katsuki as he shut the door. “Come one Deku lets cleanup for Auntie.”
“R-Right!” Izuku stuttered and turned around quickly to go back to the living room to clean. “How long do you think it will take him?” He asked once they were away from the bathroom door and as Katsuki went to get the supplies from under the kitchen sink.
“His quirk literally is called Cremation so by my guess not long. His fire burns hotter than what they use to actually cremate bodies and normal time frame for someone of shit-stains size would be about hour and a half to two hours.” Katsuki said standing with the carry crate of supplies. He looked to the other teen and frowned at the look the other was giving him. “What’s that fucking look for Deku huh?!? You want to fight?!”
“What? No! No no no I’m just wondering how kacchan knows all of that.” Izuku quickly waved his hands in the air placatingly even if he had a smile at him knowing Katsuki was messing with him on the second comment.
Thew blond shrugged turning his back to his boyfriend as he tossed a small hand dust brush and pan to him. “I get bored sometimes and go one info dives. You do the same thing nerd so don’t think it is weird. Now go sweep up the glass from the picture frames and clean the living room I’m going to clean up the soot in the front hallway and around the door.”
“Right! And I don’t think it is weird by the way Kacchan. I just didn’t know. Call me when you do one and I'll learn with you.”
Katsuki kept his back turned away feeling his cheeks heat up but he let out a grunt in reply taking the carry crate towards the front door. “Whatever you damn nerd.”

Thirty minutes is how long it took for Dabi to walk out of the now boiling hot bathroom. His jacket taken off and slung over his shoulder as he strolled out taking a look at the mostly clean apartment, he was left in a short heathered grey shirt with red trims on the arms and him of the shirt. Katsuki was still scrubbing at the walls to get the marks off in the hallway but the front door was open so he could easily see down the hall to watch him for a moment. Blue eyes quickly went to where the other teen was fixing little things that were out of order a pile of ruined couch pillows and what looked like a singed shirt by the corner of the couch. “You have a broom I can barrow to sweep up in there? It’s too hot right now for you to go in there but I can do it really quick before I go. I opened the window in there as well as turned the vent on so hopefully that will help the heat get out quickly but it’s definitely not advised for you to go int there just yet.”
“Uh y-yeah I'll grab the big set really quick.”Izuku replied to him as he moved from what he was doing to grab the large broom and dust pan from the pantry
“Also send me a list of what needs to be replaced and your mom’s favorite flowers I’ll get the items replaced and flowers for the trouble. You and Grenade should probably try to take her out for dinner or something.” Dabi continued watching as the teen brought him the broom.
“No, no you’ve done more than enough Dabi! You don’t need to do that.” Izuku is shaking his head as Katsuki walks back onto the apparent allowing the door to shut behind him, “Kacchan tell him he doesn't have to replace what Hisashi ruined.”
The blond frowned at the two and looked to the pile of stuff before shrugging. “My parents are probably going to spoil Auntie for a good while because of this so there really isn’t a need to do that.”
“Flowers then at least?” Dabi asked looking between the two of them. He would feel odd to not at least get something for the person they both cared for so deeply to kill a man over. “At least let me get some flowers send to her.”
“Uhhh she loves orchids. Green ones I think the best but she loves all of them.” Izuku finally answered as Katsuki went to put the cleaning supplies back where they went. And he watched as the unofficial/official big brother of his whole class nod before going to clean up the bathroom of what he assumed would be ashes of what remained of his shit father.
“Nerd you good?”
Izuku jumped at the voice next to him and turned to see Katsuki, back from putting away the supplies, who was frowning at him red eyes showing his worry even if the rest of his demeanor shouted annoyance. “Yeah, I’m good.... really good actually. Are we staying here or going to your house tonight?”
“If you say so. Let’s go back to mine. Show Auntie we aren’t dead, tell her she doesn’t have to worry about Dickhead any longer, and then get our project done before bed. I’m sure my parents will insist on her staying with them for a few days at the very least so it’s the better option.” the blond replied after a moment to think the question over. He knew Auntie Inko would be worried about them she always was by how much she texted them each throughout their internships and work studies while they were at UA. And with it being Izuku’s own sperm donor that was the source of them being in ‘danger’ by her standards she definitely was going to be worried about them until they saw her again, so the sooner they saw her the better for her.
“I’ll walk you two there. Pidgeon can follow in the sky just to make sure you kids get there safe.”
Izuku jumped as Dabi reappeared near them and Katsuki glared at the older male a snarl pulling at his lip. “Jesus fuck Bacon Bits you need a bell!” He growled before rolling his eyes. “And we don’t need you’re or Feather Head’s escort to my place. We’ll be fine. Pretty sure we have proven that more than enough times.”
Dabi shrugged, he’s heard the bell comment more than a few times before from some of the League members. “Don’t care. You’re getting one whether you like it or not brat.”
Katsuki groaned loudly as he rolled his eyes knowing he wasn’t going to win that argument. “Let's get our shit and go Deku. Faster we get there the faster we get rid of this Ash-hole.”Izuku laughed at his wordplay and went to go fetch their backpacks from where they had put them. “Whatever you say Kacchan.”
---
Auntie rushed them as soon as they got to Katsuki's house hugging them both tightly and checking them over and fussed over the blonds burnt and blistered palm. “Auntie it’s fine I promise. I’m going to treat it as soon as I get up to my room.”
“Yeah mom, Kacchan will be fine he always is. When we get back to UA on Monday, I'll make sure he goes to see Recovery Girl to get it fully healed back for training.” Izuku said watching his mother fuss over them allowing her to squeeze him extra tight. “I promise mom we’re okay, and we don’t have worry about him anymore.”
“He won’t be back again. He’s gone. For Good.” they said together.
