Changing fate for humanity (two readers x aot)

Part 1. How we met...

Akuma's POV.
10 years old
I was sitting on a stool with my mother in a chair behind me brushing my long blond hair...
She was humming a song...
"Mummy? What's that song?" I ask her still facing forward...
"It's a song that your father used to sing to me before he left to fight" she said calmly...
My father would come visit this small town often and would spend a whole day with me and mum...
I felt the hairbrush pull on my hair as I looked out the open door...
There were multiple kids playing and running around outside...
One of them I recognised as my friend Connie...
He was laughing and running away from another kid...
My mother grabbed a hair tie and tied my hair up in a high ponytail...
Then we heard a few screams...
The kids ran back to their houses...
My mother stood up and walked up to the door...
Then she froze in fear...
The only times I had seen her scared were if I was in danger...
"Mummy?"  I ask getting out of my seat...
I walk up to her and tug on her dress...
She was as still as a statue face frozen in fear...
I looked outside...
There was a tall creature that looked like a man...
It was tall though...
And had no clothes...
I had heard of these creatures...
Titans...
I ran back to my room and slid under my bed...
Should I stay here?
No mummy is in danger...
I grabbed the heavy sword my dad gave me for protection...
Mother didn't know about it...
I heard her bloodcurdling shriek...
I dragged the sword behind me...
I saw the titan in our house...
He was on top of my mother...
I saw her horrified face...
"RUn..." she screamed at me as a pool of red liquid spilled out of her...
The titan had it all over his face and it looked at me with a malicious smile...
I stared at it blankly...
Sword held tightly in my hands...
Was she dead?
Am I too late?
I raised the sword up high as the titan tried to stand...
I dropped the sword then grabbed a chair and hit the titan on the back of the head knocking it over...
I then grabbed the sword and yelled just plain yelling as I hacked at the Titans neck...
My father had told me about a Titans only weakness...
The back of the neck...
It finally stopped moving and there were multiple deep cuts in the nape...
I gasped for air...
I was out of breath...
I felt tears falling down my cheek...
I looked down at my white dress now covered in blood splatters...
I hugged the blood soaked sword and cried...
Connie poked his head into the room...
He saw me crying and the dead titan...
"EVERYONE AKUMA KILLED IT" he yelled out then ran to my side...
He hugged me and started asking if I was ok...
I just stared at my dead mother...
I subconsciously lifted my hand and held my ponytail tightly...
I heard multiple shouts out side and then a familiar voice...
"AKUMA, AKUMA BABY PLEASE BE ALRIGHT" I heard my father shout...
I looked up and saw his horrified face...
His blond hair pulled back and his tall strong but slim figure was standing tall and proud...
But when he saw my mothers dead body...
He was over come by grief...
He picked me up...
And held me close...
We got on his horse...
I was still clutching the sword...
It wasn't a sword that my father would use fighting...
It was one he made on his own...
It was heavy but it felt right to hold... like it was apart of me...
I placed my free hand to my neck...
And that was the last time...
I ever saw that village...

Akira's pov.

I was sitting in the kitchen.
I was hacking away at a piece of wood.
I got up and walked over to one of the draws.
I grabbed a knife.
I went and sat back down.
I started carving the wood into something.
I was home alone for another hour before I heard the door open.
"LEVI SHES GOT A KNIFE" I heard my aunt Hange yell.
"Good on her" I heard him mumble.
"Aw hey Akira what are you making?" Petra asked.
I held up what I was carving out of the wood.
"I'm making a knife with a knife" I told her, smiling.
"You can tell she's your kid from a mile away Levi" Hange laughed.
Levi crouched in front of me.
He studied the knife I was making.
"Come here kiddo" he lifted me up and placed me on his lap.
He grabbed both knifes.
He carved at the wooden one until it looked as sharp as the knife he was using to carve it with.
"Here kiddo, now you can defend yourself" he placed the wooden knife gently in my hand.
I gazed at the knife as he stood up to put the other one away.
"Levi you're making her more scary" Petra chuckled.
"Scary means she can protect others, that's a good thing" he replied bluntly.
I stood up as there was a knock on the door.
I climbed up to look out the window.
There was a horse tied to the fence.
And there was uncle Erwin.
Holding a little girl around my age.
I jumped down off the window sill.
"ITS UNCLE ERWIN" I shouted and I ran to the door.
I had to jump to reach the handle.
But when I opened the door I saw the girl he was holding properly.
She looked terrified as she clutched a bloody sword close to her chest.
Awesome.
I stepped out of Erwins way as he ran inside.
"Erwin what happened?" Hange cried out.
"Wholly mother of titans is that blood on her?!" Petra shrieked.
Levi walked up to Erwin.
"Cute kid" was all he said.
He came over and picked me up.
I got a better look at the girl.
I smiled at her.
She looked at me with wide eyes.
And she smiled back.
As the adults talked I got down from Levi's arms and I pulled her out of Erwins grasp.
I took her hand and we went to the lounge room.
I turned to her.
"What happened? Did you stab someone?" I asked her with a twinkle in my eyes.
She chuckled.
"A titan" she croaked.
"WOW THATS AWESOME! Can I see the sword?"
She hesitated, then passed the sword to me.
I stared at it in awe.
I reached into my pocket and pulled out my knife.
I passed it to her and she stared at it.
I tilted my head.
I stood up onto my tip toes and patted her on the head.
I was never good and comforting.
She giggled.
We talked for hours as she warmed up to me.
After a while we sneaked past all the grownups.
We ran out onto the streets.
The sun was going down.
"Follow me" I told her.
I walked up to a wall with a pipe going up it.
I climbed up with ease.
She followed me up with more difficulty.
The roof we were on was flat.
I walked up to the nest of blankets and pillows I had set up.
"My dad and I always come out here to watch the new recruits train" I told her.
Almost instantly I looked up and saw multiple people dressed up in the same uniform I see everyday.
They flew around the city with amazing speed.
I noticed the girl was looking up aswell.
I giggled then spread my arms and pretended to fly.
"When I grow up I'm going to join the survey corps, how about you?" I asked her.
"Yeah... I will too" she smiled at me.
We both watched the survey corps fly through the sky as we pretended we could fly aswell.
We laughed the night away.
Me and my new best friend.
