All for One's daughter (MHA x Child!Reader)

♡✿ Chapter 52 She will destroy everything ✿♡

"Where are they?" Shigaraki used his new Search quirk as he searched for Izuku Midoriya, the One For All 9th user, as well as (Y/n) but right now... he's after Deku.

The small being in Aizawa's arms started to stir as her colorless (E/c) eyes slowly opened. Eraser Head looked down at the girl and felt his heart warm over with joy of having his unofficial adopted daughter in his arms again.

"Za...za?" He nodded and quickly gave her a kiss on the forehead, making the girl blush slightly.

Her lifeless eyes lit up as tears slipped passed her. She had forgotten how much this man meant to her but more importantly how much Eri meant to her. The (C/h) haired girl looked around and only saw the big blue sky surrounding them,"Where's... Eri?"

"She's safe. She's back home. She misses you, a lot. She can barely sleep at night knowing you're far away from her..." At that saying, (Y/n)'s heart broke. She began quietly sobbing in Aizawa's arms while he held her tight.

"I didn't mean to... i-I didn't... have a... choice." He kissed her forehead yet again,"I know. She knows. I promise you, I'll take you back home..."

The heroes landed onto the dusty and hard ground. Eraser Head leaned onto Rock Lock as his arms held tightly onto (Y/n) as her sobbing started to die down.

"But first... I need you to hold on tight, (Y/n). I promise I won't let you go. Ever. I'll protect you." Aizawa erasered Shigaraki's quirk before he could even disintegrate the dragon hero, Ryukyu, who then flew straight into the clear blue sky,"In order to take you down... Shigaraki. Don't lay a finger on my students! Or (Y/n)!"

The tiny girl looked up and saw Shigaraki, the man she had started to call Master, and felt her blood run ice-cold. Her hands tighten around Aizawa's hero clothing as she buried her head into his chest.

Aizawa kept his red glowing eyes onto Shigaraki while Endeavor began to fight him,"It wouldn't been better to look at him after hiding, but..."

"But if he were to touch the ground again during that time..." Water started to float into Aizawa's eyes to make it easier on his eyes to which he thanked Manual,"No problem. If I go overboard, it'll make your eyes sting, so we'll have to work together."

"Eraser, do you want me to take the child and run?" One of the heroes asked but was quickly shut down,"No, I need to keep her in my arms or else Shigaraki will come after her. And we can't have that..."

Meanwhile back to Present Mic who had stopped and saw the fight going on in the sky between Endeavor vs Shigaraki. He had started to regret leaving (Y/n) with Aizawa but tried to convince himself she's better off being protected by his husband.

"Even though he's got super power, he's not as strong as All Might. Over-engineering his body would have burdened his brain."

"What kind of monster did you create?"

"Would you like to learn a secret?" Mic looked over at the ugly doctor,"He's not the only one you should be scared of..."

• Flashback •

"Is it ready?" All For One asked waiting patiently for the syringe to be finished.

"Ready, just one last thing." Doctor Kyudai Garaki said while holding the syringe with purple lucid flowing inside.

"And that is?" The King of Evil asked once he saw the doc grab an egg. The Doctor smiled sinisterly,"Rather be born from a woman... or an egg."

"An egg? You're joking right?"

"Would you rather find a woman willing to die and wait 9 months or wait a few weeks? Your choice." AFO's smile widened,"Fine, an egg will do. Anything else I must know?"

"The child will have your blood and once it's born, be prepared to see it's quirks straight away."

"Why does it have my blood?"

"I thought it'd be more fun and interesting. For all we know the child could turn out just like you Maybe the same gender and interests. A copy if you will." AFO's smile widened even more,"Wonderful. I'll then raise the child as my own and make sure nothing and no one stands in our way."

~~~~~~21 days later~~~~~~

Crack...

"It's... It's... A female? That can't be right, I made sure about my calculations, it must be a boy. A male."

"Well it's a girl."

"I can see that." The doc said sarcastically while trying to examine the very small child but she wouldn't stop struggling,"Stay still."

((A/N) Quick Note: since she's born out of an egg, she's the size of your palm)

You could see that tears were building up on her eyelashes and that she didn't want to be touched. The doc ignored her whining and tried again. AFO grabbed the doc's arm,"Stop."

"Fine. Remember she's your responsibility. Girls are emotional and can never get the job done. Good lu-"

"Frankly, I don't need luck. She's going to be amazing. Strong and powerful. Make me proud, her father. My daughter... Is going to surpass me and all Heroes. If not then Shigaraki will make use of her. "

The doc chuckled, "If you're so sure. Just call me if you change your mind. Oh and..." The doc pulled out a small jar of purple liquid out of his pocket,"I call it " POWER UP ". It's her blood but mixed with Nomu blood and Special Chemicals of All the powerful Quirks I could find. Be careful and inject it into her every few years or months. I'm going to have to do it now so that her small body can take all the Quirks she has and will get. She'll be in extreme pain but it will pass after 24 hours."

All for One nodded but was worried and suspicious. He didn't like the idea of his precious daughter being in pain but if it was for power then may it so be. Power is all All For One really wanted, Especially if it'll bring down the Hero society. Bring destruction to every part of the world until nothing is left,"She will destroy everything. Even if I have to force her to submit to Me... her Otosa."
