Attack On Titan Oneshots [mostly au] {requests closed!}

We're not even related - Kid!Levi x Kid!Reader AU

I had a cute idea for this so yeah. You're sorta adopted. Levi's mom found you with a note while walking from the store and took you home.

In this, you are 4 years younger than Levi. At the beginning, Levi is 8 and you're 4.

NOT INCEST I SWEAR. Well you aren't really related so I can't really make it incest..

LEVI'S POV

"Levi, go play with (y/n) around town. Don't go too far." I nodded at my mom and went to go find my sister. Well, adopted sister. Mom even went through the trouble of dying her roots black every other month. Of course, (y/n) is too young to understand that that was what she was doing.

"(Y/n)!" I heard her giggling as I walked. I smiled a bit at how she always loved to play hide and go seek.

"(Y/n), lets go play outside!" She continued to laugh and I knew I would have to find her, although I already knew where she was. I pushed the door to her room open and the giggling got louder. I stepped into the middle and stood there, looking around as if I was having trouble finding her. Then I felt weight on my back.

"You're taking me outside onii-chan?" I looked over my shoulder at the sparkling (e/c) eyes and nodded. (Y/n) smiled brightly and she climbed on my back properly.

"Let's go!" She pointed forward and
we left the house.

"Where do you want to go?"

"Swing set!" She pointed to the swing set not five steps away from us. I stood her up on her feet and she ran over to a swing and sat down.

"Push me!" She flailed her arms around and I smiled at her, stepping behind the girl and lightly pushing her forward. (Y/n) kicked her feet merrily back and forth, propelling herself even higher. She was giggling and it brought an almost permanent smile to my face.

"Aren't you out late?" (Y/n) was oblivious to the boy standing a few feet behind the swing set. He couldn't be older than I was. Did he go to school with (y/n)?

"It kinda hurts you don't remember me. I'm in your class. " I still don't remember, but I'll pretend.

"What of it?" I snarled at him. (Y/n) was standing next to me and stared wide eyed at the blonde boy.

"Your sister is quite the troublemaker. She even had the guts to throw scissors at me. " I looked down at the (h/c) haired girl and she nodded her head.

"And?" Unconsciously, I had my hand out in front of (y/n), pushing her back behind me.

"I think I should repay her. "

"Try as you might, that's not gonna happen. She's a pain in the ass sometimes, but I'll do anything to keep her from getting hurt."

"That's pretty big talk for a 3rd grader," He said with a smirk.

"Well I mean it."

TIMESKIP

"Levi!" A now 11 year old (Y/n) jumped on my back and I shot forward, but luckily I didn't fall.

"Oi, get off of me. "

"Nope," she popped the 'p' before continuing to speak, "Are you ready to babysit today? It isn't the other kids you hate. " I sighed. Not that I hated babysitting, just some of those babies are so nasty. Throwing food, gagging. Ew.

"Yeah, yeah I know. Now get off. " This time she obliged and we walked home together.

"Welcome home (y/n) and Levi." Our mom greeted, standing next to Kalura, Eren's mother, with the aforementioned child in her arms. (Y/n) nodded towards both of them, immediately going towards Eren, playing with his very short brown hair and poking his face.
