The warrior turned hero (AOT x MHA various x Fem! reader)

CHAPTER 15: I'LL PROTECT YOU, JUST AS I KNOW YOU'D PROTECT ME

(3rd PERSON POV)

"Y/n!" A voice shouted as explosions began to sound in the back. "Katsuki and the others are here. Come on, get up! We have to go."

"Armin?" The soldier rolled over, landing harshly on her knees, steam coming off her. "You fuckers started without me."

"This is serious... I'm almost out of gas. Got any ideas?" Armin was covered in blood and a green goo-like substance. His hair was disheveled and so was his stained uniform; he had a few scratches that were slowly healing.

"No... but you can have mine. Besides you look like shit." She handed him the containers. Both of them were hiding behind some bushes.
He paused before answering.

"You'll die out here without it." He refused her offer. "I think it's better if-"

"Armin..." She sighed, her tone mocking the absurdity of his statement. "Unlike you, I know how to control my transformations without creating nuclear explosions and killing thousands. You don't. So unless you want to either die or kill us all, I suggest you take this and stop complaining." She handed Armin the bottles once again. This time, he took them.

The girl then took a look at the fight happening in the plaza. Katsuki, shoto, izuku and Ejiro had arrived and had now neutralized the portal villain which arrived promptly after Y/n flew out of nomu's arms. They still however, were facing the hand villain and the nomu.

"Armin." The girl called out, standing up. "They need cover." He stopped rambling having understood perfectly what she wanted him to do. Her voice and her presence had, at times, a narcotic effect.

"Let's go."

Bakugo katsuki had always flaunted his lighting speed reflexes. That's why, when the nomu was ordered to attack him so quickly... he was surprised. He just didn't have enough time to react. But he was even more surprised when nothing happened to him. Not one scratch.
Because instead of hitting him the nomu hit someone else, someone stronger than him. And katsuki would hate to admit it, but at that point he started to realize that maybe Y/n, the girl that took the hit for him, was probably a figure he would never reach; strength wise that is.

In a mater of seconds y/n leaped from her hiding spot and managed to create some body armor for herself. The hit she took for Bakugo sent her crashing onto the wall behind. And, although it was strong at times, her armor cracked just after the hit and promptly crumbled to the ground, exposing her now bleeding forearms.

"You protected the kid?" He approached the soldier who had was just barely recovering from the hit. "That's so interesting, right? How the world will see you as a hero for stopping us even after everything you've done, desertor." This last statement caught everyone's attention, not just Y/n.

"You don't know anything about me." Scoffing, she retrieved her swords, ready to fight him once again.

"Certainly, there are a few things I don't know... but i know enough." She laughed anger building up as she began to walk slowly towards him. "I know that sacrifice is one's greatest virtue, even greater than courage..."

She froze.

Those words... it had been too long...

"Don't worry Reiner! I'm sure everything is going to end up alright. We'll win the war against the islanders our loved ones will be waiting home for us!" The ten year old looked up at the crying boy and wiped off his tears.

"Thank you Y/n. You always know how to calm me down." The blonde boy smiled softly.

"It's nothing really. My cousin says that sacrifice is one's greatest virtue, even greater than courage." She smiled as they walked.

"Wow. Your cousin must be really awsome!"

"He is!!"
.
.
"Y/n!! I'm here!" His voice echoed through the house

"Zeke! Im so happy to see you! How was training? Any news?" The seven year old ran to tackle him into a hug.

"No..." he laughed, lifting the child in the air to hug her back. "But my mentor Mr. Xaver did tell me a very important phrase today and I think you should hear it too."

"Oh tell me! I wanna know!" She smiled, still in his arms.

"He told me that sacrifice is one's greatest virtue, even greater than courage. Fascinating, Right?"

The split second that y/n was out of it felt like an eternity for everyone else. But just as soon as she was distracted she came back, this time however, she was angrier.

"Nomu the kids... kill them-"

Shigaraki didn't have time to finish the sentence as the sound of an Odm gear cut him off. Armin swiftly zipped through the air cutting straight through the nape as if it were a titan who he was facing. This gave Todoroki enough time to react and freeze the beast in place. The blonde landed rather clumsily but immediately went into fighting stance, protecting the others as they too prepared their quirks for what could come next.

Shigaraki groaned at the inconvenience.
"I'll just kill them myself then... starting with you."

The fight between Y/n and shigaraki lasted a few minutes. Meanwhile the boys were busy sending attacks from every direction to try to distract the nomu, while also keeping an eye out in case that Y/n needed backup. Armin knew that if Y/n had to use her titan form he would have to clear up the area before she could. Otherwise she would essentially kill whoever what in her range of explosion. What he didn't expect what for Y/n to have to resort to it so quickly.

All it took was one wrong move for Y/n to loose the upper hand she had. After she lost her second place to the quirk of the villain she decides to just use her fists. What she wasn't expecting was for the crystals to decay so quickly. She didn't have time to react, as the hand of the villain made contact with her own flesh she started feeling a tingly sensation which quickly became a burning one. She was being skinned alive.
The boys looked back at her as they heard a small cry.

It was a quick decision and in a matter of seconds she withdrew her last sword and instinctively cut off her hand to avoid the decaying process from spreading further.

"You're crazy..." the villain laughed as he walked back a little bit.

"I..." she breathed heavily as blood oozed out of her arm. "Yes." She spat before turning on her heel and running straight for the boys.

Armin, seeing the blood and the sparks surrounding her grabbed the nearest person he had by the waist, and used the Odm gear to propel himself to the ceiling. Todoroki was not amused but instead opted to grab tighter on to Armin as to avoid slipping down and falling to his death.

Y/n ran towards Kirishima, Midoriya and Bakugo, yelling at them to sto where they were. As she reached them the sparks became more visible. She grabbed on to them and whispered an apology before setting her power loose.

The explosion that came afterwards and smoke that was produced was enough for everyone in the USJ to see. And as the air around them cleared up a big figure appeared on the plaza.

It had no lower body relying on its rib cage to stand upright. The flesh on it was almost completely gone leaving the skeleton almost entirely visible. Behind the ribs were the three heroes in training, shielded by one of the creature's bony hands. The thing began to move its other hand in an attempt to swat away the villains like pesky flies.
As the three guys attempted to make their way out of their living prison they noticed that it had picked the nomu, albeit with some struggle and was now aiming to throw it out. It succeeded, as right when the doors opened revealing All might the nomu was flung out the USJ and into the surrounding areas of it.
