The Special Zoldyck Sister

This is 100 percent a Hunter X Hunter fanfic and I don't own any of the characters made up in this story. All those credits go to the creator of HxH, Yoshihiro Togashi.

Y/n is the youngest member of the Zoldyck family, one year younger then the former youngest sibling Kalluto. Just like Killua, she was born with white hair which meant she had just as much potential as he did to become the boss of the household. Since she was born like this, Illumi also became obsessed with her and decided that only he would train y/n and that if anybody touched her it would infuriate him; even if it was his younger brother Killua. After Killua finally gets Alluka from his family, he makes it a plan to take back now nine year old y/n back from the hands of his cold older sibling Illumi. Will Killua be able to do it? And if he does how will Illumi and the other members of the Zoldyck family react.
