Into The One Piece World As Ace's Sister

The Beginning

I sighed when I woke up as a baby and I saw a kid with freckles holding me. I panicked in my head when I realized that the kid was the Portgas D. Ace. I began to cry when I realized that me and Ace were orphans and that I had to deal with Garp. Ace began to panic as he tried to get me to stop crying.
"Don't worry Anne, Nii-chan is here to protect you." Said Ace which made me stop crying.
I fell asleep to Ace humming a lullaby.
-four years later-
I walked around the forest only to trip over a fruit which looked blood red with black and white swirls. My stomach growled and I ate it only to gag from the taste of it. I felt something poke my arm and I looked to see a demon tail.
"Cool!! I have a tail!!" I said excitedly.
(I ate a devil fruit without thinking. I'm gonna call it the Akuma-Akuma no mi. Today's the day I'll meet Luffy and hopefully Shanks.) I thought with a sweat drop.
I ran back to the bandits hut and I ran to Ace as Ace's eyes widened in surprise from how I look.
"Nii-chan!! Nii-chan!! Look I have a tail!!" I said.
"I see that. You also have pointed ears. How?" Asked Ace.
"Well I ate this strange looking fruit." I said.
Ace sighed when he heard me and dragged me over to Dadan and Ace explained to Dadan about what happened to me.
"That sounds like a devil fruit. I thought that devil fruits were myths." Said Dadan.
