Please don't leave me (sanji x oc)

First Encounter

( I don't own any of the One Piece characters just Emi and Tsubaki)

As I was running through the middle of town, I disregarded everything around me and just focused on running, running, running from the sick and twisted man that is Tsubaki. If I hadn't been so breathless and tired I would be sobbing over my farther. I have no idea were I'm going but I soon got a reminder of the fact that I don't care were I'm going all I know is it just need's to be safe.He was the only family that I had left and now he's gone to, and it's all Tsubaki's fault he killed my farther, and now he's after me. 

As if on cue I hear his sickening voice causing me to trip and stumble as he say's

"Men get her, NOW I want her dead do you hear me!"

Before I could fully re jester what he said I was cornered by his men with him slowly advancing towards me.

I cried for help knowing full well no one would step in and help me, but I still tried with halfhearted cry's but as I said earlier no one did or said anything to stop them because they to were afraid of what Tsubaki could do. 

I took a deep calming breath and then slowly reached for my knife getting ready to through it at Tsubaki. I stopped reaching for my knife as I heard someone screaming about...

"MMEEAATT!!!! " 

Meat? What I saw next left me speechless a boy who looked to be about 18-19 just sent Tsubaki flying . wait is that... That's Monkey D. Luffy! captain of the straw hat pirates. 

"MMEEAATT!!! oh wait were am I???"

I mentally face palmed when he said that. All of Tsubaki's men where in utter shock that a boy like him could send there boss flying the way Luffy did.

" Hey you, you just sent our boss flying now your going to pay with your life".

One of Tusbaki's men went to shoot Luffy but once he did they soon found out that bullets don't affect him because they bounced off him and shot off into random  directions,

With all this going on I took this as an opportunity to make a quick getaway, but I didn't get to far when I bumped into someone and as I looked up my stomach dropped at the site of non other then Tsubaki himself. 

" So were do you think your going Emi".

I was so scared that I turned on my heels and went to run but I was picked up by Tsubaki. He put me in a choke hold and said to Luffy.

" If you want this girl to live you'll have to pay her farther's dept for her or she'll face the same fate that he did".

At the mention of my farther's death I broke out into muffled sobs as you let all the tears I held in fall to the ground. Then I heard Luffy say something that shoked you to the core.

"LET MY LITTLE SISTER GO RIGHT NOW!!!"

Wait what??? did he just say little sister but I don't have any siblings, well not that I know of I don't. This can't be but if it's true does that mean that I'm adopted???

Please let me know what you think seeing as It's my first book ever and I could really use the constructive criticism :)
