A hero of justice [My hero academia x Shirou Emiya]

With Midoriya and Tsu
Shoto lay on the floor unable to use his quirk, Midoriyas hand was being crushed by the aggressive grip of the Nomu. "It's over heroes!" Shigaraki jumps forward putting his hand on Tsu's face... "You are a truly amazing eraser head..." despite the incredible injuries he'd received Aisawa raised his head and activated his quirk saving her life. "Nomu." It beast instantly dropped Midoriya and moved to stop Aizawas head into the floor.

With a defining crack Aizawas head impacted into the floor, "now let's try that again." Once again Shigaraki reached for Tsu who was too afraid to stop him. "Trace on..." immediately two blades barely miss his head! "I won't let you!" Shirou arrives jumping forward swinging both his blades towards the villain forcing him to retreat.

CRASH the ridiculously loud noise echos through the USJ, villains are flung from the entrance. "The final boss has arrived." by now Shigaraki knew who this was.

"I AM HERE."
Allmight had arrived, he grabbed his tie and threw it. He wasn't smiling... in an instant, he was speeding around the USJ taking out villains. But Shirou had already traced a blade and jumped towards Shigaraki, it was Dyrnwyn! It burst into flames as he swung it down a Shigaraki barely missing his face. "NOMU!" Shigaraki screamed as the beast sped towards Shirou hitting him in the side and throwing him a good distance away.

But before he landed Mineta; who arrived with Shirou. threw a tiny purple ball out of his hair, that landed just beneath him.
It grew in size and saved Shirou from the damage. In an instant, All might have grabbed all the students nearby and moved them out the way. "Get back to the entrance now! Carry Aizawa!" Shirou without before the others had even reacted had grabbed Aizawa and moved, he knew he couldn't take on that beast. Every instinct in his body told him so. "You were wrong father, he's still strong... without me even realizing he hit me... truly, this is the power of the symbol of peace. Kurogiri you know what to do."

"Carolina Smash!" Allmight jumped forward with his hands in an X formation, swinging them he struck Nomu's body. But soon another portal opened, out this one came a more skinny, taller Nomu. "Project 2, kill the children." In an instant, it was gone. Running towards Shirou and the rest. It was about to hit them but a barrage of swords rained from above. "Hmm? You think this will be enough?" Momo had arrived, the 2 nomu had barely dodged the first barrage before the second came. "You take Aizawa, I'll take this thing with Momo." Shirou handed Aizawas's body to Mineta as he picked him up and ran with the rest of the group towards the front.

"I didn't think I'd be fighting alongside you, Momo." Trace on. A long Chinese guandao formed in his hands, Qièshí jī the stone crusher. "Neither, but at the very least you're capable. Unlike the others in this class." Momo looked down on most of this class. She wasn't sure about heroics. She did it out of self duty after all, but she couldn't even begin to comprehend why others would want to do this out of choice. The beast jumped forward, Creation! 6 large swords pierced her opponent. Qièshí jī swung and immediately severed its head from its body. Shirou was normally against killing, but it was obvious these things were no longer human. "Detonation!" Momo swung her hand and the swords exploded reducing the beast to ash.

But it didn't stay down for long. It only took a few seconds for the beast to be back in full condition and rushing towards them. "Regeneration? No multiplication." Turning around Shirou cut down the new beast that had snuck upon them. "Every time we defeat it, it duplicates?" Now they were in trouble, "this is bad! Momo we can only hold on for so long!" Shirou shouted to his sister whose swords swung around her impairing the Nomu. "Give me a minute! I can work this out soon!" Momo was confident that she could work out its weakness. After all, no quirk was completely invincible. "Hurry up!" But as Shirou shouted, one Nomu managed to break through his defence.
