Hunter x Hunter ( New Character Added )

This fan fic is about a character named Takara Adachi who has a xxy chromosome. They were born half male and half female.
She doesn't care what she is called gender wise so I'm going to stick with she/her.
At a very young age her family decided to make her an assassin. They abused her and ripped her soul out of her body. At the age of five she had already killed 100 people. They weren't just pedestrians, they were trained assassins. She new everything. She could endure any kind of pain, no matter what it was. At 18 years of age she left wanting to do the hunter exam because she was bored. And that was when she ran into...Them.
