Wild girl

Kia is a girl who lived on the wild side of life(when she was away from her parents) she tried to run away several times to see the world, but was brought back every time. She is like a sister to Hisoka and he cares deeply for her, he isn't like this with anyone else. Is she like his sister, or is she really his sister? That is the question. She doesn't know why he avoids the question of why he treats her so well, and she wants to know. She meets this assassin boy who seems to know who she is, the only problem is she didn't think he would even remember she existed. Will she find love with him or a mysterious black haired bandit? That is my question. Hisoka is slightly ooc it goes with my idea. I don't own hunter x hunter. Only Kia and her family. Who she ends up with is undecided it is either killua or feitan search them if you don't know who they are I need help on deciding. Please vote and comment on my story.
