Chapter Text
They had been back from the training camp for about a week, yet Lunch Rush had already begun conducting a cooking class, because apparently they didn't know how to cook themselves. Class 1-A were being their usual rowdy selves, only a portion of them stopping to listen to their teacher's next instructions. Everyone had been paired off and sent to their own benches, and so only some groups were getting along. Some weren't due to one person not wanting to follow the rules and the other wanting to get the dish perfect.
And some groups were super awkward. Case in point: Bakugou and Midoriya.
Bakugou kept adding in triple the amount of ingredients that made curry as spicy as it was, all while yelling at Midoriya to shut up whenever he tried to intervene.
It had been fifteen minutes of Bakugou yelling at Midoriya, and as each minute would go by, Midoriya would get quieter. So quiet to the point where he wasn't even talking. He did everything Bakugou told him to do without any objections, and even Bakugou was getting worried about it. He glanced at Midoriya chopping the onions and said quietly, "What the hell is up with you?"
Midoriya ignored him and continued to do his assigned task. Bakugou frowned before going back to seasoning the beef, occasionally glancing at Midoriya out of the corner of his eye, just to make sure he was alright. In the middle of one of these glances, Bakugou noticed that Midoriya was clutching onto his stomach, wincing in pain. Bakugou didn't say anything, thinking maybe the shorter boy just knocked his stomach or something.
"Alright," Bakugou said. "hand me the fucking onio–"
He was interrupted when there was loud clutter next to him. He whipped his head to look at Midoriya, his assumptions that there was something wrong with Midoriya being correct, but much worse than he thought.
Midoriya had fallen to the ground, laying on his side and curled up in a ball. He was clutching his stomach with both arms now, breathing heavily as sweat dripped off his forehead. The chopping board he was working on was next to him, along with the diced-up onion. The knife was dangerously close to his back, and Bakugou kicked it out of the way before kneeling next to Midoriya's shaking body.
"Oi," Bakugou shouted. "What the hell is wrong?!"
He didn't get a response, and more panic set in him when Midoriya coughed up a large amount of blood. The dark red substance splattered onto the white tiles, some getting onto Bakugou's apron.
"What the fuck. . ." Bakugou mumbled to himself before looking back at Midoriya, hesitantly placing his hand on his shoulder. "Deku, are you good?!"
Obviously he wasn't, but Bakugou didn't know what else to do. The class had begun to look now.
Bakugou noticed something out of the corner of his eye, so he looked at it. In front of his face was the knife Midoriya had been using, and he froze. It was floating by itself, along with the chopping board and onion. It reminded him of something, but he couldn't place his finger on it.
"Kacchan. . ." Midoriya choked out, and Bakugou hesitantly looked back at Midoriya, keeping the knife in his sight. "Ye-Yeah, what?"
"Move away, Kacchan." The smaller boy wheezed out, rolling onto his back as his breathing got heavier.
"Why the fuck should I–" Bakugou was interrupted when Midoriya shoved him out of the way, only just before flames erupted from the green-haired kid's mouth. The whole class screamed in fright, Bakugou staring up at the orange flames in shock.
What. . . the fuck. . .
The flames died down, and that's when Midoriya started almost convulsing in pain, yelling as tears streamed down his face.
It was all a blur: Bakugou swiping Midoriya up in his arms; bringing him to the front of the classroom where Lunch Rush had already taken the shaking boy; running through the halls to Recovery Girl; conversations that almost sounded like they were underwater to Bakugou; getting in the ambulance; Midoriya squeezing Bakugou's hand with a deathly grip; the sound of Bakugou's bones in his hands snapping and the sharp pain that ran through from the force of One For All; Midoriya being wheeled through the corridors of the hospital; the white hospital rooms; nurses; darkness.
Bakugou woke up two hours later on a hospital bed, the pillow crackling from underneath his head as he shifted underneath the heavy cotton blanket. The sound of beeping came from next to him, and he looked over to see Midoriya. Laid down in a similar bed, Midoriya's blanket was up to his chin, keeping him warm from the harsh air conditioning. He had an IV needle at his veins in the crevice of his left arm, the IV drip hanging up next to him. His breathing was heavy now, and fresh scratches were visible on his arms.
Bakugou got out of his bed, but as he did so, his hand throbbed in pain, and he winced, letting out a small 'shit'. He looked at his hand, a white cast around it. He sighed, remembering when Midoriya's quirk activated on its own, crushing Bakugou's hand in the process while he held his hand.
He ignored it and walked over to Midoriya, sitting down in the chair next to the bed. Not long after he did this, Inko and All Might walked into the room, conversing worriedly. They noticed him.
"Oh, Katsuki! How are you feeling?" Inko asked, trying her best to smile. Bakugou appreciated effort and replied with a small 'fine'.
"Thank you for being there for him, Young Bakugou." All Might said, and Bakugou nodded before looking away and back to Midoriya.
"What the hell do you think happened to him?" He asked, and Inko sat in the chair next to him while All Might stood at the foot of the bed.
"I think his quirks manifested." All Might spoke up immediately. Bakugou frowned at him. "What?"
But he then realised. That's what was so familiar about the knife and the chopping board floating. It reminded him of Midoriya's mother's quirk. And the fire breathing. . .
His father's. Midoriya's dad's quirk was fire breathing. He remembered hearing about this when they were kids.
Midoriya had three fucking quirks going at the same time and his body couldn't handle it.
Inko's phone began to ring, and so she excused herself and left the room to answer the call.
"So what you're saying is," Bakugou said, beginning to grow agitated. "Midoriya's quirk manifested ten years late, and because everyone gave up hope, you gave him a new ass quirk, completely disregarding the fact that maybe miracles might be a fucking thing?"
Bakugou tried being as quiet as possible, remembering that Inko doesn't know about One For All.
All Might sighed before saying, "As much as I'd love to take responsibility for this, Young Bakugou, I think this would have caused Young Midoriya the same amount of pain if he had just the two. His body is halfway through developing, and to have done that without a quirk, it would have adapted to that. So for his quirks to manifest out of nowhere would have come as a shock to his body, whether he had One For All or not."
"No," Bakugou said, glaring at the former number one hero. "Just like everyone else, including myself, you thought Midoriya had no chance at having a quirk. Midoriya would not have gone through as much pain as he did when inheriting two more quirks. If two more quirks are battling with one that already exists, I think that would tend to be more fucking painful. So don't play the innocent card where his pain comes partly from you."
"Kacchan. . ."
Bakugou looked at the boy, and his heart almost snapped in half. Midoriya looked too weak to even wake, and when he talked, Bakugou could just see the blood and bruising on his tongue, most likely from when he was biting down on it from the pain.
All Might left without a word, and Bakugou sat in silence, slouched in his chair, before saying, "They're saying you inherited two quirks."
Midoriya's eyes widened at the news, "Really?"
"Yeah. And on top of that, you broke my fucking hand using One For All. Thanks for that."
Midoriya looked down in shame, mumbling, "Sorry, Kacchan."
Bakugou knew it wasn't just him. The apology sounded less genuine than it usually was. However, he ignored it and sat with Midoriya as they waited for the doctors to come in.
