What about Aizawa becoming blind because he protected his class and the other Pro Heros didn't come fast enough?
//It’s nineteen minutes past two in the morning but it’s DONE. Enjoy, you sadistic buggers.
As Aizawa’s face was smashed into the hard ground a fifth time, he’d accepted the fact that no help was coming. Thirteen was injured – too injured to protect the children – so that left only him.
Noumu dragged him up once again by his tangled hair, and in the few seconds he had, he made eye contact with the horrified Deku (who was still recovering from the shock of him saving Tsuyu) and mouthed, Get them all to the gate. The boy didn’t receive the message clearly, however, and Aizawa managed, with the aid of sheer adrenaline, to fight against the force Noumu was applying to the back of his bleeding head. He braced himself on his one good forearm, minding the elbow, and pushed up, looking at Deku desperately.
“Gate! Go – everyone!” his voice was cracked and croaky, but the boy nodded in reluctant understanding before disappearing from Aizawa’s sight as his battle was lost and he was pushed to the ground once more.
“So noble,” the voice of Tomura pierced the heavy air. “Letting them leave while you stay here and die. However, you forget”-he pulled Aizawa’s face from the ground and closer to his own-“that Noumu is not the only villain here.”
Acting out of pure instinct, Aizawa used the support the two hands were giving him and arched his back to release his own. He then proceeded to take two lengths of his scarf and wrap them around Tomura’s neck, relishing in the surprise the one visible eye showed.
“Don’t…fucking touch my…students.” Each growled word was accentuated by a sharp tug of the scarf, and even as he was struggling to retain consciousness, his ragged breathing an indicator of this, he grinned. Tomura winced at the savage look, the bloodstained face and teeth a picture of pure malice, before fainting from lack of oxygen. Kurogiri soon removed him from the scene.
Even as he fell once more onto the concrete, Aizawa smiled.
Even as he was turned onto his back and punched repeatedly in the face, Aizawa smiled.
And he continued to smile as his he brought his legs up and kicked Noumu’s beak-like face. The damage he delivered was minimal – if existent – but the fact that the man could still move caught the creature off-guard. He rolled out from beneath it, noticing how the world had lost much of its colour, and used the arm that was not completely twisted and broken to bring himself to his feet. He collapsed as soon as he’d succeeded.
Noumu grinned as he made his way over to Aizawa’s motionless body. The Pro tried to move away, but found exhaustion had finally taken over him and his limbs were useless. His eyesight was dimming, a feeling of irritation at the back of his eyeballs and the surrounding area, but that wasn’t his main concern. No – his primary focus was the large foot approaching his mangled face at a rapid speed, but then it wasn’t a concern any more because it made contact and he was unconscious.
Mic had never activated his Quirk as quickly as he did when he saw his best friend’s lifeless body being shadowed by a giant, mutated villain. The noise threw it away from its target and he left it to be sorted out by the other Pros while he sprinted towards Aizawa, All Might a few paces in front. Lifting the bloody, broken body in a fireman’s lift upon reaching him, the latter carried him back to Mic, who was slightly behind due to his shorter legs.
“I-is he alive?” he peered at the mess of a face and almost burst into tears at the sight of it. “Shouta? Shouta, can you hear me?”
A brief moment passed before dried lips whispered, “Yamada? Are…they safe?”
“Yes,” tears were streaming down his face, a relieved smile gracing it. “Yes, all thanks to you. And you’re going to be fine. Everyone’s going to be fine.”
Dark eyelashes slowly fluttered open but there was no sign of recognition in the cracked, bloodshot eyes beneath.
“Yamada… Why can’t I see anything?”
“Thanks to your teacher, none of you were seriously injured. So make sure you all let him know how grateful you are when he recovers.”
Tsuyu approached the man desperately. “But is he okay? Aizawa-sensei – will he be okay?”
The man gave her a sympathetic smile and produced his phone from a pocket, informing them that the doctor had left a message.
“He suffers from several fractures to the face and arms, and while he – luckily – got away with no serious brain injuries, the damage to Eraserhead’s orbital floor was too great, so the floor and rim of the sockets are fractured. Unfortunately, he has permanently lost his sight. I’m sorry, there’s nothing we can do.”
The class of 1-A was silent; some were crying. It was Iida who finally spoke.
“He’s lost his Quirk, then? Since he needs to look at the person…”
“Yes, that is what we must assume.”
“But why?” Tsuyu cried. “He just wanted to protect us. He kept fighting, even through all that pain… He doesn’t deserve this.”
Bakugou narrowed his eyes. “There’s no point in being sad for him – I think Present Mic is taking care of that – so all we can do is help him and let him know he’s not alone.”
The steady, quiet beeping of the heart monitor was the only thing breaking the silence of the hospital room. Present Mic sat on the plastic chair, staring at his lifelong friend through sad, watery eyes.
“It’s my fault, Shouta,” he whispered. “I should have arrived sooner. If I had, you’d still be able to see; you wouldn’t be in this bed-”
“The first long sleep in ages and you yitter on through it.” A deep, slightly muffled voice muttered jokingly.
“Mm. What’s on my eyes? Move it; I can’t see anything.”
Taking the cast-wrapped hand in his own, Mic sighed. “That’s the difficult part. You- There was a lot of damage to your face and head. Your brain’s fine, but your eyes… You’re blind, Shouta.”
“'Oh’? That’s it?”
The hero did his best to shrug. “What’s done is done. No point in being upset over it. Are the children okay?”
“They’re fine.” He shook his head. “So you’re not the least bit upset? You’re absolutely fine with this?”
Aizawa frowned beneath the bandages, the small movement creating no small amount of pain. “I suppose I’ll be upset about not seeing them all grow into great heroes… But I’ll still be there; I’ll hear them and be with them.”
Mic scoffed. “What about your Quirk?”
“I can train myself to use the scarf and stuff again, and maybe there’s a way I can use it without seeing whoever I’m using it on. Who knows? I’ll find out.”
“Aizawa!” All Might appeared in the doorway, concerned expression being replaced by relief. “How are you? Feeling any better?”
“Yes, I’m fine.” The Pro Hero smiled, thinking of all the faces in his class, safe and well. All it took was a small sacrifice. “It’ll all be fine.”
//Part two here
