(Kingdom hearts) the heartless mortal

After kingdom hearts 2 a little girl was born in the realm of darkness with a little big error in her she had a body legs arms and basically your normal human girl but her body had a giant hollowed out heart shape on her body.
(she has a heart shaped hole going straight threw her body basically)

This means she has no heart and after wondering Around a bit she saw a heartless but it wasn't attacking her for some reason. but then a big adult wearing a dark hoodie came over and saw darkness in her and took her as his own then showing her too organisation IIIX then went somewhere unknown But the girl was adult age now so it was fine.

And now the girl named Jessica btw could now talk and understand her heartless brethren (Because she was like half human half heartless) and she even had her own guardsmen. she was going to have one heck of a time in this world.

I don't own kingdom hearts and I also and only know the 3ed game so if I miss any lore bits i apologies for that but anyway lets start this book up
